* Address review feedback, add CLI dispatch, interactive gates, and docs

Review comments (7/7):
- Add explanatory comment to empty except block
- Implement workflow catalog download with cleanup on failure
- Add input type coercion for number/boolean/enum
- Fix example workflow to remove non-existent output references
- Fix while_loop and if_then condition defaults (string 'false' → bool False)
- Fix resume step index tracking with step_offset parameter

CLI dispatch:
- Add build_exec_args() and dispatch_command() to IntegrationBase
- Override for Claude (skills: /speckit-specify), Gemini (-m flag),
  Codex (codex exec), Copilot (--agent speckit.specify)
- CommandStep invokes installed commands by name via integration CLI
- Add PromptStep for arbitrary inline prompts (10th step type)
- Stream CLI output live to terminal (no silent blocking)
- Remove timeout when streaming (user can Ctrl+C)
- Ctrl+C saves state as PAUSED for clean resume

Interactive gates:
- Gate steps prompt [1] approve [2] reject in TTY
- Fall back to PAUSED in non-interactive environments
- Resume re-executes the gate for interactive prompting

Documentation:
- workflows/README.md — user guide
- workflows/ARCHITECTURE.md — internals with Mermaid diagrams
- workflows/PUBLISHING.md — catalog submission guide

Tests: 94 → 122 workflow tests, 1362 total (all passing)

* Fix ruff lint errors: unused imports, f-string placeholders, undefined name

* Address second review: registry-backed validation, shell failures, loop/fan-out execution, URL validation

- VALID_STEP_TYPES now queries STEP_REGISTRY dynamically
- Shell step returns FAILED on non-zero exit code
- Persist workflow YAML in run directory for reliable resume
- Resume loads from run copy, falls back to installed workflow
- Engine iterates while/do-while loops up to max_iterations
- Engine expands fan-out per item with context.item
- HTTPS URL validation for catalog workflow installs (HTTP allowed for localhost)
- Fix catalog merge priority docstring (lower number wins)
- Fix dispatch_command docstring (no build_exec_args_for_command)
- Gate on_reject=retry pauses for re-prompt on resume
- Update docs to 10 step types, add prompt step to tables and README

* Potential fix for pull request finding 'Empty except'

Co-authored-by: Copilot Autofix powered by AI <223894421+github-code-quality[bot]@users.noreply.github.com>

* Address third review: fan-out IDs, catalog guards, shell coercion, docs

- Fan-out generates unique per-item step IDs and collects results
- Catalog merge skips non-dict workflow entries (malformed data guard)
- Shell step coerces run_cmd to str after expression evaluation
- urlopen timeout=30 for catalog workflow installs
- yaml.dump with sort_keys=False, allow_unicode=True for catalog configs
- Document streaming timeout as intentionally unbounded (user Ctrl+C)
- Document --allow-all-tools as required for non-interactive + future enhancement
- Update test docstring and PUBLISHING.md to 10 step types with prompt

* Validate final URL after redirects in catalog fetch

urlopen follows redirects, so validate the response URL against the
same HTTPS/localhost rules to prevent redirect-based downgrade attacks.

* Address fourth review: filter arg eval, tags normalization, install redirect check

- Filter arguments now evaluated via _evaluate_simple_expression() so
  default(42) returns int not string
- Tags normalized: non-list/non-string values handled gracefully
- Install URL redirect validation (same as catalog fetch)
- Remove unused 'skipped' variable in catalog config parsing
- Author 'github' → 'GitHub' in example workflow
- Document nested step resume limitation (re-runs parent step)

* Add explanatory comment to empty except ValueError block

* Address fifth review: expression parsing, fan-out output, URL install, gate options

- Move string literal parsing before operator detection in expressions
  so quoted strings with operators (e.g. 'a in b') are not mis-parsed
- Fan-out: remove max_concurrency from persisted output, fix docstring
  to reflect sequential execution
- workflow add: support URL sources with HTTPS/redirect validation,
  validate workflow ID is non-empty before writing files
- Deduplicate local install logic via _validate_and_install_local()
- Remove 'edit' gate option from speckit workflow (not implemented)

* Add comments to empty except ValueError blocks in URL install

* Address sixth review: operator precedence, fan_in cleanup, registry resilience, docs

- Fix or/and operator precedence (or parsed first = lower precedence)
- Restore context.fan_in after fan-in step completes
- Catch JSONDecodeError in registry load for corrupted files
- Replace print() with on_step_start callback (library-safe)
- Gate validation warns when on_reject set but no reject option
- Shell step: document shell=True security tradeoff
- README: sdd-pipeline → speckit, parallel → sequential for fan-out
- ARCHITECTURE.md: parallel → fan-out/fan-in in diagram

* Address seventh review: string literal before pipe, type annotations, validate on install

- Move string literal check above pipe filter parsing so 'a | b' works
- Fix type annotations: input_values list[str] | None, run_id str | None
- Run validate_workflow() before installing from local path/URL
- Remove duplicate string literal check from expression parser

* Address eighth review: fan-out namespaced IDs, early return, catalog validation

- Fan-out per-item step IDs use _fanout_{step_id}_{base}_{idx} namespace
  to avoid collisions with user-defined step IDs
- Early return after fan-out loop when state is paused/failed/aborted
- Catalog installs parse + validate downloaded YAML before registering,
  using definition metadata instead of catalog entry for registry

* Address ninth review: populate catalog, fix indentation, priority, README

- Add speckit workflow entry to catalog.json so it's discoverable
- Fix shell step output dict indentation
- Catalog add_catalog priority derived from max existing + 1
- README Quick Start clarified with install + local file examples

* Address tenth review: max_iterations validation, catalog config guard, version alignment

- Validate max_iterations is int >= 1 in while and do-while steps
- Guard add_catalog against corrupted config (non-dict/non-list)
- Align speckit_version requirement to >=0.6.1 (current package version)
- Fan-out template validation uses separate seen_ids set to avoid
  false duplication errors with user-defined step IDs

* Address eleventh review: command step fails without CLI, ID mismatch warning, state persistence

- Command step returns FAILED when CLI not installed (was silent COMPLETED)
- Catalog install warns on workflow ID vs catalog key mismatch
- Engine persists state.save() before returning on unknown step type
- Update tests to expect FAILED for command steps without CLI
- Integration tests use shell steps for CLI-independent execution

* Address twelfth review: type annotations, version examples, streaming docs, requires

- Fix workflow_search type annotations (str | None)
- PUBLISHING.md: speckit_version >=0.15.0 → >=0.6.1
- Document that exit_code is captured and referenceable by later steps
- Mark requires as declared-but-not-enforced (planned enhancement)
- Note full stdout/stderr capture as planned enhancement

* Enforce catalog key matches workflow ID (fail instead of warn)

* Bundle speckit workflow: auto-install during specify init

- Add workflows/speckit to pyproject.toml force-include for wheel builds
- Add _locate_bundled_workflow() helper (mirrors _locate_bundled_extension)
- Auto-install speckit workflow during specify init (after git extension)
- Update all integration file inventory tests to expect workflow files

* Address fourteenth review: prompt fails without CLI, resolved step data, fan-out normalization

- PromptStep returns FAILED when CLI not installed (was silent COMPLETED)
- Engine step_data prefers resolved values from step output
- Fan-out normalizes output.results=[] for empty item lists
- subprocess.run inherits stdout/stderr (no explicit sys.stdout)
- Registry tests use issubset for extensibility

* Address fifteenth review: fan_in docstring, gate defaults, validation guards, reserved prefix

- FanInStep docstring: aggregate-only, no blocking semantics
- FanInStep: guard output_config as dict, handle None
- Gate validate: use same default options as execute
- Validate inputs is dict and steps is list before iterating
- Reserve _fanout_ prefix in step ID validation
- PUBLISHING.md: remove unenforced checklist items, add _fanout_ note

* Address sixteenth review: docs regex, fan_in try/finally, hyphenated dot-path keys

- PUBLISHING.md: update ID regex docs to match implementation (single-char OK)
- FanInStep: wrap expression evaluation in try/finally for context.fan_in
- Expression dot-path: allow hyphens in keys before list index (e.g. run-tests[0])

* Make speckit workflow integration-agnostic, document Copilot CLI requirement

- Workflow integration selectable via input (default: claude)
- Each command step uses {{ inputs.integration }} instead of hardcoded copilot
- Copilot docstring documents CLI requirement for workflow dispatch
- Added install_url for Copilot CLI docs

* Address seventeenth review: project checks, catalog robustness

- Add .specify/ project check to workflow run/resume/status/search/info
- remove_catalog validates config shape (dict + list) before indexing
- _fetch_single_catalog validates response is a dict
- _get_merged_workflows raises when all catalogs fail to fetch
- add_catalog guards against non-dict catalog entries in config

* Address eighteenth review: condition coercion, gate abort result, while default, cache guard, resume log

- evaluate_condition treats plain 'false'/'true' strings as booleans
- Gate abort returns StepResult(FAILED) instead of raising exception
  so step output is persisted in state for inspection
- while_loop max_iterations optional (default 10), validation aligned
- Catalog cache fallback catches invalid JSON gracefully
- resume() appends workflow_finished log entry like execute()

* Address nineteenth review: allow-all-tools opt-in, empty catalogs, abort dead code, while docstring

- --allow-all-tools controlled by SPECKIT_ALLOW_ALL_TOOLS env var (default: 1)
  Set to 0 to disable automatic tool approval for Copilot CLI
- Empty catalogs list falls back to built-in defaults (not an error)
- Remove unreachable WorkflowAbortError catches from execute/resume
  (gate abort now returns StepResult(FAILED) instead of raising)
- while_loop docstring updated: max_iterations is optional (default 10)

* Address twentieth review: gate abort maps to ABORTED status, do-while max_iterations optional

- Engine detects output.aborted from gate step and sets RunStatus.ABORTED
  (was unreachable — gate abort returned FAILED but status was always FAILED)
- do-while max_iterations now optional (default 10), aligned with while_loop
- do-while docstring and validation updated accordingly

* Coerce default_options to dict, align bundled workflow ID regex with validator

* Gate validates string options, prompt uses resolved integration, loop normalizes max_iterations

* Use parentId:childId convention for nested step IDs

- Fan-out per-item IDs use parentId:templateId:index (e.g. parallel:impl:0)
- Reserve ':' in user step IDs (validation rejects)
- Replaces _fanout_ prefix with cleaner namespacing
- Expressions like {{ steps.parallel:impl:0.output.file }} work naturally

* Validate workflow version is semantic versioning (X.Y.Z)

* Schema version validation, strict semver, load_workflow docstring, preserve max_concurrency

- Validate schema_version is '1.0' (reject unknown future schemas)
- Strict semver regex: ^\d+\.\d+\.\d+$ (rejects 1.0.0beta etc.)
- load_workflow docstring: 'parsed' not 'validated'
- Keep max_concurrency in fan-out output (was dropped)
- do_while docstring: engine re-evaluates step_config condition
- ARCHITECTURE.md: document nested resume limitation

* Path traversal prevention, loop step ID namespacing

- RunState validates run_id is alphanumeric+hyphens (no path separators)
- workflow_add validates catalog source doesn't escape workflows_dir
- Loop iterations namespace nested step IDs as parentId:childId:iteration
  so multiple iterations don't overwrite each other in context/state

+# Release Process
+
+This document describes the automated release process for Spec Kit.
+
+## Overview
+
+The release process is split into two workflows to ensure version consistency:
+
+1. **Release Trigger Workflow** (`release-trigger.yml`) - Manages versioning and triggers release
+2. **Release Workflow** (`release.yml`) - Builds and publishes artifacts
+
+This separation ensures that git tags always point to commits with the correct version in `pyproject.toml`.
+
+## Before Creating a Release
+
+**Important**: Write clear, descriptive commit messages!
+
+### How CHANGELOG.md Works
+
+The CHANGELOG is **automatically generated** from your git commit messages:
+
+1. **During Development**: Write clear, descriptive commit messages:
+   ```bash
+   git commit -m "feat: Add new authentication feature"
+   git commit -m "fix: Resolve timeout issue in API client (#123)"
+   git commit -m "docs: Update installation instructions"
+   ```
+
+2. **When Releasing**: The release trigger workflow automatically:
+   - Finds all commits since the last release tag
+   - Formats them as changelog entries
+   - Inserts them into CHANGELOG.md
+   - Commits the updated changelog before creating the new tag
+
+### Commit Message Best Practices
+
+Good commit messages make good changelogs:
+- **Be descriptive**: "Add user authentication" not "Update files"
+- **Reference issues/PRs**: Include `(#123)` for automated linking
+- **Use conventional commits** (optional): `feat:`, `fix:`, `docs:`, `chore:`
+- **Keep it concise**: One line is ideal, details go in commit body
+
+**Example commits that become good changelog entries:**
+```
+fix: prepend YAML frontmatter to Cursor .mdc files (#1699)
+feat: add generic agent support with customizable command directories (#1639)
+docs: document dual-catalog system for extensions (#1689)
+```
+
+## Creating a Release
+
+### Option 1: Auto-Increment (Recommended for patches)
+
+1. Go to **Actions** → **Release Trigger**
+2. Click **Run workflow**
+3. Leave the version field **empty**
+4. Click **Run workflow**
+
+The workflow will:
+- Auto-increment the patch version (e.g., `0.1.10` → `0.1.11`)
+- Update `pyproject.toml`
+- Update `CHANGELOG.md` by adding a new section for the release based on commits since the last tag
+- Commit changes to a `chore/release-vX.Y.Z` branch
+- Create and push the git tag from that branch
+- Open a PR to merge the version bump into `main`
+- Trigger the release workflow automatically via the tag push
+
+### Option 2: Manual Version (For major/minor bumps)
+
+1. Go to **Actions** → **Release Trigger**
+2. Click **Run workflow**
+3. Enter the desired version (e.g., `0.2.0` or `v0.2.0`)
+4. Click **Run workflow**
+
+The workflow will:
+- Use your specified version
+- Update `pyproject.toml`
+- Update `CHANGELOG.md` by adding a new section for the release based on commits since the last tag
+- Commit changes to a `chore/release-vX.Y.Z` branch
+- Create and push the git tag from that branch
+- Open a PR to merge the version bump into `main`
+- Trigger the release workflow automatically via the tag push
+
+## What Happens Next
+
+Once the release trigger workflow completes:
+
+1. A `chore/release-vX.Y.Z` branch is pushed with the version bump commit
+2. The git tag is pushed, pointing to that commit
+3. The **Release Workflow** is automatically triggered by the tag push
+4. Release artifacts are built for all supported agents
+5. A GitHub Release is created with all assets
+6. A PR is opened to merge the version bump branch into `main`
+
+> **Note**: Merge the auto-opened PR after the release is published to keep `main` in sync.
+
+## Workflow Details
+
+### Release Trigger Workflow
+
+**File**: `.github/workflows/release-trigger.yml`
+
+**Trigger**: Manual (`workflow_dispatch`)
+
+**Permissions Required**: `contents: write`
+
+**Steps**:
+1. Checkout repository
+2. Determine version (manual or auto-increment)
+3. Check if tag already exists (prevents duplicates)
+4. Create `chore/release-vX.Y.Z` branch
+5. Update `pyproject.toml`
+6. Update `CHANGELOG.md` from git commits
+7. Commit changes
+8. Push branch and tag
+9. Open PR to merge version bump into `main`
+
+### Release Workflow
+
+**File**: `.github/workflows/release.yml`
+
+**Trigger**: Tag push (`v*`)
+
+**Permissions Required**: `contents: write`
+
+**Steps**:
+1. Checkout repository at tag
+2. Extract version from tag name
+3. Check if release already exists
+4. Build release package variants (all agents × shell/powershell)
+5. Generate release notes from commits
+6. Create GitHub Release with all assets
+
+## Version Constraints
+
+- Tags must follow format: `v{MAJOR}.{MINOR}.{PATCH}`
+- Example valid versions: `v0.1.11`, `v0.2.0`, `v1.0.0`
+- Auto-increment only bumps patch version
+- Cannot create duplicate tags (workflow will fail)
+
+## Benefits of This Approach
+
+✅ **Version Consistency**: Git tags point to commits with matching `pyproject.toml` version
+
+✅ **Single Source of Truth**: Version set once, used everywhere
+
+✅ **Prevents Drift**: No more manual version synchronization needed
+
+✅ **Clean Separation**: Versioning logic separate from artifact building
+
+✅ **Flexibility**: Supports both auto-increment and manual versioning
+
+## Troubleshooting
+
+### No Commits Since Last Release
+
+If you run the release trigger workflow when there are no new commits since the last tag:
+- The workflow will still succeed
+- The CHANGELOG will show "- Initial release" if it's the first release
+- Or it will be empty if there are no commits
+- Consider adding meaningful commits before releasing
+
+**Best Practice**: Use descriptive commit messages - they become your changelog!
+
+### Tag Already Exists
+
+If you see "Error: Tag vX.Y.Z already exists!", you need to:
+- Choose a different version number, or
+- Delete the existing tag if it was created in error
+
+### Release Workflow Didn't Trigger
+
+Check that:
+- The release trigger workflow completed successfully
+- The tag was pushed (check repository tags)
+- The release workflow is enabled in Actions settings
+
+### Version Mismatch
+
+If `pyproject.toml` doesn't match the latest tag:
+- Run the release trigger workflow to sync versions
+- Or manually update `pyproject.toml` and push changes before running the release trigger
+
+## Legacy Behavior (Pre-v0.1.10)
+
+Before this change, the release workflow:
+- Created tags automatically on main branch pushes
+- Updated `pyproject.toml` AFTER creating the tag
+- Resulted in tags pointing to commits with outdated versions
+
+This has been fixed in v0.1.10+.

+
+## About Spec Kit and Specify
+
+**GitHub Spec Kit** is a comprehensive toolkit for implementing Spec-Driven Development (SDD) - a methodology that emphasizes creating clear specifications before implementation. The toolkit includes templates, scripts, and workflows that guide development teams through a structured approach to building software.
+
+**Specify CLI** is the command-line interface that bootstraps projects with the Spec Kit framework. It sets up the necessary directory structures, templates, and AI agent integrations to support the Spec-Driven Development workflow.
+
+The toolkit supports multiple AI coding assistants, allowing teams to use their preferred tools while maintaining consistent project structure and development practices.
+
+---
+
+## Integration Architecture
+
+Each AI agent is a self-contained **integration subpackage** under `src/specify_cli/integrations/<key>/`. The subpackage exposes a single class that declares all metadata and inherits setup/teardown logic from a base class. Built-in integrations are then instantiated and added to the global `INTEGRATION_REGISTRY` by `src/specify_cli/integrations/__init__.py` via `_register_builtins()`.
+
+```
+src/specify_cli/integrations/
+├── __init__.py            # INTEGRATION_REGISTRY + _register_builtins()
+├── base.py                # IntegrationBase, MarkdownIntegration, TomlIntegration, YamlIntegration, SkillsIntegration
+├── manifest.py            # IntegrationManifest (file tracking)
+├── claude/                # Example: SkillsIntegration subclass
+│   ├── __init__.py        #   ClaudeIntegration class
+│   └── scripts/           #   Thin wrapper scripts
+│       ├── update-context.sh

+├── copilot/               # Example: IntegrationBase subclass (custom setup)
+│   ├── __init__.py
+│   └── scripts/
+└── ...                    # One subpackage per supported agent
+```
+
+The registry is the **single source of truth for Python integration metadata**. Supported agents, their directories, formats, and capabilities are derived from the integration classes for the Python integration layer. However, context-update behavior still requires explicit cases in the shared dispatcher scripts (`scripts/bash/update-agent-context.sh` and `scripts/powershell/update-agent-context.ps1`), which currently maintain their own supported-agent lists and agent-key→context-file mappings until they are migrated to registry-based dispatch.
+
+---
+
+## Adding a New Integration
+
+### 1. Choose a base class
+
+| Your agent needs… | Subclass |
+|---|---|
+| Standard markdown commands (`.md`) | `MarkdownIntegration` |
+| TOML-format commands (`.toml`) | `TomlIntegration` |
+| YAML recipe files (`.yaml`) | `YamlIntegration` |
+| Skill directories (`speckit-<name>/SKILL.md`) | `SkillsIntegration` |
+| Fully custom output (companion files, settings merge, etc.) | `IntegrationBase` directly |
+
+Most agents only need `MarkdownIntegration` — a minimal subclass with zero method overrides.
+
+### 2. Create the subpackage
+
+Create `src/specify_cli/integrations/<package_dir>/__init__.py`, where `<package_dir>` is the Python-safe directory name derived from `<key>`: use the key as-is when it contains no hyphens (e.g., key `"gemini"` → `gemini/`), or replace hyphens with underscores when it does (e.g., key `"kiro-cli"` → `kiro_cli/`). The `IntegrationBase.key` class attribute always retains the original hyphenated value, since that is what the CLI and registry use. For CLI-based integrations (`requires_cli: True`), the `key` should match the actual CLI tool name (the executable users install and run) so CLI checks can resolve it correctly. For IDE-based integrations (`requires_cli: False`), use the canonical integration identifier instead.
+
+**Minimal example — Markdown agent (Windsurf):**
+
+```python
+"""Windsurf IDE integration."""
+
+from ..base import MarkdownIntegration
+
+
+class WindsurfIntegration(MarkdownIntegration):
+    key = "windsurf"
+    config = {
+        "name": "Windsurf",
+        "folder": ".windsurf/",
+        "commands_subdir": "workflows",
+        "install_url": None,
+        "requires_cli": False,
+    }
+    registrar_config = {
+        "dir": ".windsurf/workflows",
+        "format": "markdown",
+        "args": "$ARGUMENTS",
+        "extension": ".md",
+    }
+    context_file = ".windsurf/rules/specify-rules.md"
+```
+
+**TOML agent (Gemini):**
+
+```python
+"""Gemini CLI integration."""
+
+from ..base import TomlIntegration
+
+
+class GeminiIntegration(TomlIntegration):
+    key = "gemini"
+    config = {
+        "name": "Gemini CLI",
+        "folder": ".gemini/",
+        "commands_subdir": "commands",
+        "install_url": "https://github.com/google-gemini/gemini-cli",
+        "requires_cli": True,
+    }
+    registrar_config = {
+        "dir": ".gemini/commands",
+        "format": "toml",
+        "args": "{{args}}",
+        "extension": ".toml",
+    }
+    context_file = "GEMINI.md"
+```
+
+**Skills agent (Codex):**
+
+```python
+"""Codex CLI integration — skills-based agent."""
+
+from __future__ import annotations
+
+from ..base import IntegrationOption, SkillsIntegration
+
+
+class CodexIntegration(SkillsIntegration):
+    key = "codex"
+    config = {
+        "name": "Codex CLI",
+        "folder": ".agents/",
+        "commands_subdir": "skills",
+        "install_url": "https://github.com/openai/codex",
+        "requires_cli": True,
+    }
+    registrar_config = {
+        "dir": ".agents/skills",
+        "format": "markdown",
+        "args": "$ARGUMENTS",
+        "extension": "/SKILL.md",
+    }
+    context_file = "AGENTS.md"
+
+    @classmethod
+    def options(cls) -> list[IntegrationOption]:
+        return [
+            IntegrationOption(
+                "--skills",
+                is_flag=True,
+                default=True,
+                help="Install as agent skills (default for Codex)",
+            ),
+        ]
+```
+
+#### Required fields
+
+| Field | Location | Purpose |
+|---|---|---|
+| `key` | Class attribute | Unique identifier; for CLI-based integrations (`requires_cli: True`), must match the CLI executable name |
+| `config` | Class attribute (dict) | Agent metadata: `name`, `folder`, `commands_subdir`, `install_url`, `requires_cli` |
+| `registrar_config` | Class attribute (dict) | Command output config: `dir`, `format`, `args` placeholder, file `extension` |
+| `context_file` | Class attribute (str or None) | Path to agent context/instructions file (e.g., `"CLAUDE.md"`, `".github/copilot-instructions.md"`) |
+
+**Key design rule:** For CLI-based integrations (`requires_cli: True`), `key` must be the actual executable name (e.g., `"cursor-agent"` not `"cursor"`). This ensures `shutil.which(key)` works for CLI-tool checks without special-case mappings. IDE-based integrations (`requires_cli: False`) should use their canonical identifier (e.g., `"windsurf"`, `"copilot"`).
+
+### 3. Register it
+
+In `src/specify_cli/integrations/__init__.py`, add one import and one `_register()` call inside `_register_builtins()`. Both lists are alphabetical:
+
+```python
+def _register_builtins() -> None:
+    # -- Imports (alphabetical) -------------------------------------------
+    from .claude import ClaudeIntegration
+    # ...
+    from .newagent import NewAgentIntegration   # ← add import
+    # ...
+
+    # -- Registration (alphabetical) --------------------------------------
+    _register(ClaudeIntegration())
+    # ...
+    _register(NewAgentIntegration())            # ← add registration
+    # ...
+```
+
+### 4. Add scripts
+
+Create two thin wrapper scripts in `src/specify_cli/integrations/<package_dir>/scripts/` that delegate to the shared context-update scripts. Each is ~25 lines of boilerplate.
+
+> **Note on `<package_dir>` vs `<key>`:** `<package_dir>` is the Python-safe directory name for your integration — it matches `<key>` exactly when the key contains no hyphens (e.g., key `"gemini"` → `gemini/`), but uses underscores when it does (e.g., key `"kiro-cli"` → `kiro_cli/`). The `IntegrationBase.key` class attribute always retains the original hyphenated value (e.g., `key = "kiro-cli"`), since that is what the CLI and registry use.
+
+**`update-context.sh`:**
+
+```bash
+#!/usr/bin/env bash
+# update-context.sh — <Agent Name> integration: create/update <context_file>
+set -euo pipefail
+
+_script_dir="$(cd "$(dirname "$0")" && pwd)"
+_root="$_script_dir"
+while [ "$_root" != "/" ] && [ ! -d "$_root/.specify" ]; do _root="$(dirname "$_root")"; done
+if [ -z "${REPO_ROOT:-}" ]; then
+  if [ -d "$_root/.specify" ]; then
+    REPO_ROOT="$_root"
+  else
+    git_root="$(git rev-parse --show-toplevel 2>/dev/null || true)"
+    if [ -n "$git_root" ] && [ -d "$git_root/.specify" ]; then
+      REPO_ROOT="$git_root"
+    else
+      REPO_ROOT="$_root"
+    fi
+  fi
+fi
+
+exec "$REPO_ROOT/.specify/scripts/bash/update-agent-context.sh" <key>
+```
+
+**`update-context.ps1`:**
+
+```powershell
+# update-context.ps1 — <Agent Name> integration: create/update <context_file>
+$ErrorActionPreference = 'Stop'
+
+$scriptDir = Split-Path -Parent $MyInvocation.MyCommand.Definition
+$repoRoot = try { git rev-parse --show-toplevel 2>$null } catch { $null }
+if (-not $repoRoot -or -not (Test-Path (Join-Path $repoRoot '.specify'))) {
+    $repoRoot = $scriptDir
+    $fsRoot = [System.IO.Path]::GetPathRoot($repoRoot)
+    while ($repoRoot -and $repoRoot -ne $fsRoot -and -not (Test-Path (Join-Path $repoRoot '.specify'))) {
+        $repoRoot = Split-Path -Parent $repoRoot
+    }
+}
+
+& "$repoRoot/.specify/scripts/powershell/update-agent-context.ps1" -AgentType <key>
+```
+
+Replace `<key>` with your integration key and `<Agent Name>` / `<context_file>` with the appropriate values.
+
+You must also add the agent to the shared context-update scripts so the shared dispatcher recognises the new key:
+
+- **`scripts/bash/update-agent-context.sh`** — add a file-path variable and a case in `update_specific_agent()`.
+- **`scripts/powershell/update-agent-context.ps1`** — add a file-path variable, add the new key to the `AgentType` parameter's `[ValidateSet(...)]`, add a switch case in `Update-SpecificAgent`, and add an entry in `Update-AllExistingAgents`.
+
+### 5. Test it
+
+```bash
+# Install into a test project
+specify init my-project --integration <key>
+
+# Verify files were created in the commands directory configured by
+# config["folder"] + config["commands_subdir"] (for example, .windsurf/workflows/)
+ls -R my-project/.windsurf/workflows/
+
+# Uninstall cleanly
+cd my-project && specify integration uninstall <key>
+```
+
+Each integration also has a dedicated test file at `tests/integrations/test_integration_<key>.py`. Note that hyphens in the key are replaced with underscores in the filename (e.g., key `cursor-agent` → `test_integration_cursor_agent.py`, key `kiro-cli` → `test_integration_kiro_cli.py`). Run it with:
+
+```bash
+pytest tests/integrations/test_integration_<key_with_underscores>.py -v
+```
+
+### 6. Optional overrides
+
+The base classes handle most work automatically. Override only when the agent deviates from standard patterns:
+
+| Override | When to use | Example |
+|---|---|---|
+| `command_filename(template_name)` | Custom file naming or extension | Copilot → `speckit.{name}.agent.md` |
+| `options()` | Integration-specific CLI flags via `--integration-options` | Codex → `--skills` flag |
+| `setup()` | Custom install logic (companion files, settings merge) | Copilot → `.agent.md` + `.prompt.md` + `.vscode/settings.json` |
+| `teardown()` | Custom uninstall logic | Rarely needed; base handles manifest-tracked files |
+
+**Example — Copilot (fully custom `setup`):**
+
+Copilot extends `IntegrationBase` directly because it creates `.agent.md` commands, companion `.prompt.md` files, and merges `.vscode/settings.json`. See `src/specify_cli/integrations/copilot/__init__.py` for the full implementation.
+
+### 7. Update Devcontainer files (Optional)
+
+For agents that have VS Code extensions or require CLI installation, update the devcontainer configuration files:
+
+#### VS Code Extension-based Agents
+
+For agents available as VS Code extensions, add them to `.devcontainer/devcontainer.json`:
+
+```jsonc
+{
+  "customizations": {
+    "vscode": {
+      "extensions": [
+        // ... existing extensions ...
+        "[New Agent Extension ID]"
+      ]
+    }
+  }
+}
+```
+
+#### CLI-based Agents
+
+For agents that require CLI tools, add installation commands to `.devcontainer/post-create.sh`:
+
+```bash
+#!/bin/bash
+
+# Existing installations...
+
+echo -e "\n🤖 Installing [New Agent Name] CLI..."
+# run_command "npm install -g [agent-cli-package]@latest"
+echo "✅ Done"
+```
+
+---
+
+## Command File Formats
+
+### Markdown Format
+
+**Standard format:**
+
+```markdown
+---
+description: "Command description"
+---
+
+Command content with {SCRIPT} and $ARGUMENTS placeholders.
+```
+
+**GitHub Copilot Chat Mode format:**
+
+```markdown
+---
+description: "Command description"
+mode: speckit.command-name
+---
+
+Command content with {SCRIPT} and $ARGUMENTS placeholders.
+```
+
+### TOML Format
+
+```toml
+description = "Command description"
+
+prompt = """
+Command content with {SCRIPT} and {{args}} placeholders.
+"""
+```
+
+### YAML Format
+
+Used by: Goose
+
+```yaml
+version: 1.0.0
+title: "Command Title"
+description: "Command description"
+author:
+  contact: spec-kit
+extensions:
+  - type: builtin
+    name: developer
+activities:
+  - Spec-Driven Development
+prompt: |
+  Command content with {SCRIPT} and {{args}} placeholders.
+```
+
+## Argument Patterns
+
+Different agents use different argument placeholders. The placeholder used in command files is always taken from `registrar_config["args"]` for each integration — check there first when in doubt:
+
+- **Markdown/prompt-based**: `$ARGUMENTS` (default for most markdown agents)
+- **TOML-based**: `{{args}}` (e.g., Gemini)
+- **YAML-based**: `{{args}}` (e.g., Goose)
+- **Custom**: some agents override the default (e.g., Forge uses `{{parameters}}`)
+- **Script placeholders**: `{SCRIPT}` (replaced with actual script path)
+- **Agent placeholders**: `__AGENT__` (replaced with agent name)
+
+## Special Processing Requirements
+
+Some agents require custom processing beyond the standard template transformations:
+
+### Copilot Integration
+
+GitHub Copilot has unique requirements:
+- Commands use `.agent.md` extension (not `.md`)
+- Each command gets a companion `.prompt.md` file in `.github/prompts/`
+- Installs `.vscode/settings.json` with prompt file recommendations
+- Context file lives at `.github/copilot-instructions.md`
+
+Implementation: Extends `IntegrationBase` with custom `setup()` method that:
+1. Processes templates with `process_template()`
+2. Generates companion `.prompt.md` files
+3. Merges VS Code settings
+
+### Forge Integration
+
+Forge has special frontmatter and argument requirements:
+- Uses `{{parameters}}` instead of `$ARGUMENTS`
+- Strips `handoffs` frontmatter key (Forge-specific collaboration feature)
+- Injects `name` field into frontmatter when missing
+
+Implementation: Extends `MarkdownIntegration` with custom `setup()` method that:
+1. Inherits standard template processing from `MarkdownIntegration`
+2. Adds extra `$ARGUMENTS` → `{{parameters}}` replacement after template processing
+3. Applies Forge-specific transformations via `_apply_forge_transformations()`
+4. Strips `handoffs` frontmatter key
+5. Injects missing `name` fields
+6. Ensures the shared `update-agent-context.*` scripts include a `forge` case that maps context updates to `AGENTS.md` and lists `forge` in their usage/help text
+
+### Goose Integration
+
+Goose is a YAML-format agent using Block's recipe system:
+- Uses `.goose/recipes/` directory for YAML recipe files
+- Uses `{{args}}` argument placeholder
+- Produces YAML with `prompt: |` block scalar for command content
+
+Implementation: Extends `YamlIntegration` (parallel to `TomlIntegration`):
+1. Processes templates through the standard placeholder pipeline
+2. Extracts title and description from frontmatter
+3. Renders output as Goose recipe YAML (version, title, description, author, extensions, activities, prompt)
+4. Uses `yaml.safe_dump()` for header fields to ensure proper escaping
+5. Context updates map to `AGENTS.md` (shared with opencode/codex/pi/forge)
+
+## Common Pitfalls
+
+1. **Using shorthand keys for CLI-based integrations**: For CLI-based integrations (`requires_cli: True`), the `key` must match the executable name (e.g., `"cursor-agent"` not `"cursor"`). `shutil.which(key)` is used for CLI tool checks — mismatches require special-case mappings. IDE-based integrations (`requires_cli: False`) are not subject to this constraint.
+2. **Forgetting update scripts**: Both bash and PowerShell thin wrappers and the shared context-update scripts must be updated.
+3. **Incorrect `requires_cli` value**: Set to `True` only for agents that have a CLI tool; set to `False` for IDE-based agents.
+4. **Wrong argument format**: Use `$ARGUMENTS` for Markdown agents, `{{args}}` for TOML agents.
+5. **Skipping registration**: The import and `_register()` call in `_register_builtins()` must both be added.
+
+---
+
+*This documentation should be updated whenever new integrations are added to maintain accuracy and completeness.*

+
+1. **Run focused automated checks first** — use the quick verification commands in [`TESTING.md`](./TESTING.md) to catch packaging, scaffolding, and configuration regressions early.
+2. **Run manual workflow tests second** — if your change affects slash commands or the developer workflow, follow [`TESTING.md`](./TESTING.md) to choose the right commands, run them in an agent, and capture results for your PR.

+## AI contributions in Spec Kit
+
+> [!IMPORTANT]
+>
+> If you are using **any kind of AI assistance** to contribute to Spec Kit,
+> it must be disclosed in the pull request or issue.
+
+We welcome and encourage the use of AI tools to help improve Spec Kit! Many valuable contributions have been enhanced with AI assistance for code generation, issue detection, and feature definition.
+
+That being said, if you are using any kind of AI assistance (e.g., agents, ChatGPT) while contributing to Spec Kit,
+**this must be disclosed in the pull request or issue**, along with the extent to which AI assistance was used (e.g., documentation comments vs. code generation).
+
+If your PR responses or comments are being generated by an AI, disclose that as well.
+
+As an exception, trivial spacing or typo fixes don't need to be disclosed, so long as the changes are limited to small parts of the code or short phrases.
+
+An example disclosure:
+
+> This PR was written primarily by GitHub Copilot.
+
+Or a more detailed disclosure:
+
+> I consulted ChatGPT to understand the codebase but the solution
+> was fully authored manually by myself.
+
+Failure to disclose this is first and foremost rude to the human operators on the other end of the pull request, but it also makes it difficult to
+determine how much scrutiny to apply to the contribution.
+
+In a perfect world, AI assistance would produce equal or higher quality work than any human. That isn't the world we live in today, and in most cases
+where human supervision or expertise is not in the loop, it's generating code that cannot be reasonably maintained or evolved.
+
+### What we're looking for
+
+When submitting AI-assisted contributions, please ensure they include:
+
+- **Clear disclosure of AI use** - You are transparent about AI use and degree to which you're using it for the contribution
+- **Human understanding and testing** - You've personally tested the changes and understand what they do
+- **Clear rationale** - You can explain why the change is needed and how it fits within Spec Kit's goals
+- **Concrete evidence** - Include test cases, scenarios, or examples that demonstrate the improvement
+- **Your own analysis** - Share your thoughts on the end-to-end developer experience
+
+### What we'll close
+
+We reserve the right to close contributions that appear to be:
+
+- Untested changes submitted without verification
+- Generic suggestions that don't address specific Spec Kit needs
+- Bulk submissions that show no human review or understanding
+
+### Guidelines for success
+
+The key is demonstrating that you understand and have validated your proposed changes. If a maintainer can easily tell that a contribution was generated entirely by AI without human input or testing, it likely needs more work before submission.
+
+Contributors who consistently submit low-effort AI-generated changes may be restricted from further contributions at the maintainers' discretion.
+
+Please be respectful to maintainers and disclose AI assistance.

 ## 🤔 What is Spec-Driven Development?
 
 Spec-Driven Development **flips the script** on traditional software development. For decades, code has been king — specifications were just scaffolding we built and discarded once the "real work" of coding began. Spec-Driven Development changes this: **specifications become executable**, directly generating working implementations rather than just guiding them.
 
-## ⚡ Get started
+## ⚡ Get Started
 
-### 1. Install Specify
+### 1. Install Specify CLI
 
-Initialize your project depending on the coding agent you're using:
+Choose your preferred installation method:
+
+#### Option 1: Persistent Installation (Recommended)
+
+Install once and use everywhere. Pin a specific release tag for stability (check [Releases](https://github.com/github/spec-kit/releases) for the latest):
 
 ```bash
-uvx --from git+https://github.com/github/spec-kit.git specify init <PROJECT_NAME>
+# Install a specific stable release (recommended — replace vX.Y.Z with the latest tag)
+uv tool install specify-cli --from git+https://github.com/github/spec-kit.git@vX.Y.Z
+
+# Or install latest from main (may include unreleased changes)
+uv tool install specify-cli --from git+https://github.com/github/spec-kit.git
 ```
 
-### 2. Create the spec
-
-Use the `/specify` command to describe what you want to build. Focus on the **what** and **why**, not the tech stack.
+Then use the tool directly:
 
 ```bash
-/specify Build an application that can help me organize my photos in separate photo albums. Albums are grouped by date and can be re-organized by dragging and dropping on the main page. Albums never other nested albums. Within each album, photos are previewed in a tile-like interface.
+# Create new project
+specify init <PROJECT_NAME>
+
+# Or initialize in existing project
+specify init . --ai claude
+# or
+specify init --here --ai claude
+
+# Check installed tools
+specify check
 ```
 
-### 3. Create a technical implementation plan
-
-Use the `/plan` command to provide your tech stack and architecture choices.
+To upgrade Specify, see the [Upgrade Guide](./docs/upgrade.md) for detailed instructions. Quick upgrade:
 
 ```bash
-/plan The application uses Vite with minimal number of libraries. Use vanilla HTML, CSS, and JavaScript as much as possible. Images are not uploaded anywhere and metadata is stored in a local SQLite database.
+uv tool install specify-cli --force --from git+https://github.com/github/spec-kit.git@vX.Y.Z
 ```
 
-### 4. Break down and implement
+#### Option 2: One-time Usage
 
-Use `/tasks` to create an actionable task list, then ask your agent to implement the feature.
+Run directly without installing:
+
+```bash
+# Create new project (pinned to a stable release — replace vX.Y.Z with the latest tag)
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init <PROJECT_NAME>
+
+# Or initialize in existing project
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init . --ai claude
+# or
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init --here --ai claude
+```
+
+**Benefits of persistent installation:**
+
+- Tool stays installed and available in PATH
+- No need to create shell aliases
+- Better tool management with `uv tool list`, `uv tool upgrade`, `uv tool uninstall`
+- Cleaner shell configuration
+
+#### Option 3: Enterprise / Air-Gapped Installation
+
+If your environment blocks access to PyPI or GitHub, see the [Enterprise / Air-Gapped Installation](./docs/installation.md#enterprise--air-gapped-installation) guide for step-by-step instructions on using `pip download` to create portable, OS-specific wheel bundles on a connected machine.
+
+### 2. Establish project principles
+
+Launch your AI assistant in the project directory. Most agents expose spec-kit as `/speckit.*` slash commands; Codex CLI in skills mode uses `$speckit-*` instead.
+
+Use the **`/speckit.constitution`** command to create your project's governing principles and development guidelines that will guide all subsequent development.
+
+```bash
+/speckit.constitution Create principles focused on code quality, testing standards, user experience consistency, and performance requirements
+```
+
+### 3. Create the spec
+
+Use the **`/speckit.specify`** command to describe what you want to build. Focus on the **what** and **why**, not the tech stack.
+
+```bash
+/speckit.specify Build an application that can help me organize my photos in separate photo albums. Albums are grouped by date and can be re-organized by dragging and dropping on the main page. Albums are never in other nested albums. Within each album, photos are previewed in a tile-like interface.
+```
+
+### 4. Create a technical implementation plan
+
+Use the **`/speckit.plan`** command to provide your tech stack and architecture choices.
+
+```bash
+/speckit.plan The application uses Vite with minimal number of libraries. Use vanilla HTML, CSS, and JavaScript as much as possible. Images are not uploaded anywhere and metadata is stored in a local SQLite database.
+```
+
+### 5. Break down into tasks
+
+Use **`/speckit.tasks`** to create an actionable task list from your implementation plan.
+
+```bash
+/speckit.tasks
+```
+
+### 6. Execute implementation
+
+Use **`/speckit.implement`** to execute all tasks and build your feature according to the plan.
+
+```bash
+/speckit.implement
+```

+## 🧩 Community Extensions
+
+> [!NOTE]
+> Community extensions are independently created and maintained by their respective authors. GitHub and the Spec Kit maintainers may review pull requests that add entries to the community catalog for formatting, catalog structure, or policy compliance, but they do **not review, audit, endorse, or support the extension code itself**. The Community Extensions website is also a third-party resource. Review extension source code before installation and use at your own discretion.
+
+🔍 **Browse and search community extensions on the [Community Extensions website](https://speckit-community.github.io/extensions/).**
+
+The following community-contributed extensions are available in [`catalog.community.json`](extensions/catalog.community.json):
+
+**Categories:**
+
+- `docs` — reads, validates, or generates spec artifacts
+- `code` — reviews, validates, or modifies source code
+- `process` — orchestrates workflow across phases
+- `integration` — syncs with external platforms
+- `visibility` — reports on project health or progress
+
+**Effect:**
+
+- `Read-only` — produces reports without modifying files
+- `Read+Write` — modifies files, creates artifacts, or updates specs
+

+## 🎨 Community Presets
+
+> [!NOTE]
+> Community presets are independently created and maintained by their respective authors. GitHub and the Spec Kit maintainers may review pull requests that add entries to the community catalog for formatting, catalog structure, or policy compliance, but they do **not review, audit, endorse, or support the preset code itself**. Review preset source code before installation and use at your own discretion.
+
+The following community-contributed presets customize how Spec Kit behaves — overriding templates, commands, and terminology without changing any tooling. Presets are available in [`catalog.community.json`](presets/catalog.community.json):

+> Community walkthroughs are independently created and maintained by their respective authors. They are **not reviewed, nor endorsed, nor supported by GitHub**. Review their content before following along and use at your own discretion.
+
+See Spec-Driven Development in action across different scenarios with these community-contributed walkthroughs:
+
+- **[Greenfield .NET CLI tool](https://github.com/mnriem/spec-kit-dotnet-cli-demo)** — Builds a Timezone Utility as a .NET single-binary CLI tool from a blank directory, covering the full spec-kit workflow: constitution, specify, plan, tasks, and multi-pass implement using GitHub Copilot agents.
+
+- **[Greenfield Spring Boot + React platform](https://github.com/mnriem/spec-kit-spring-react-demo)** — Builds an LLM performance analytics platform (REST API, graphs, iteration tracking) from scratch using Spring Boot, embedded React, PostgreSQL, and Docker Compose, with a clarify step and a cross-artifact consistency analysis pass included.
+
+- **[Brownfield ASP.NET CMS extension](https://github.com/mnriem/spec-kit-aspnet-brownfield-demo)** — Extends an existing open-source .NET CMS (CarrotCakeCMS-Core, ~307,000 lines of C#, Razor, SQL, JavaScript, and config files) with two new features — cross-platform Docker Compose infrastructure and a token-authenticated headless REST API — demonstrating how spec-kit fits into existing codebases without prior specs or a constitution.
+
+- **[Brownfield Java runtime extension](https://github.com/mnriem/spec-kit-java-brownfield-demo)** — Extends an existing open-source Jakarta EE runtime (Piranha, ~420,000 lines of Java, XML, JSP, HTML, and config files across 180 Maven modules) with a password-protected Server Admin Console, demonstrating spec-kit on a large multi-module Java project with no prior specs or constitution.
+
+- **[Brownfield Go / React dashboard demo](https://github.com/mnriem/spec-kit-go-brownfield-demo)** — Demonstrates spec-kit driven entirely from the **terminal using GitHub Copilot CLI**. Extends NASA's open-source Hermes ground support system (Go) with a lightweight React-based web telemetry dashboard, showing that the full constitution → specify → plan → tasks → implement workflow works from the terminal.
+
+- **[Greenfield Spring Boot MVC with a custom preset](https://github.com/mnriem/spec-kit-pirate-speak-preset-demo)** — Builds a Spring Boot MVC application from scratch using a custom pirate-speak preset, demonstrating how presets can reshape the entire spec-kit experience: specifications become "Voyage Manifests," plans become "Battle Plans," and tasks become "Crew Assignments" — all generated in full pirate vernacular without changing any tooling.
+
+- **[Greenfield Spring Boot + React with a custom extension](https://github.com/mnriem/spec-kit-aide-extension-demo)** — Walks through the **AIDE extension**, a community extension that adds an alternative spec-driven workflow to spec-kit with high-level specs (vision) and low-level specs (work items) organized in a 7-step iterative lifecycle: vision → roadmap → progress tracking → work queue → work items → execution → feedback loops. Uses a family trading platform (Spring Boot 4, React 19, PostgreSQL, Docker Compose) as the scenario to illustrate how the extension mechanism lets you plug in a different style of spec-driven development without changing any core tooling — truly utilizing the "Kit" in Spec Kit.

+## Available Slash Commands
+
+After running `specify init`, your AI coding agent will have access to these slash commands for structured development. If you pass `--ai <agent> --ai-skills`, Spec Kit installs agent skills instead of slash-command prompt files; `--ai-skills` requires `--ai`.

+
+## 🧩 Making Spec Kit Your Own: Extensions & Presets
+
+Spec Kit can be tailored to your needs through two complementary systems — **extensions** and **presets** — plus project-local overrides for one-off adjustments:
+
+| Priority | Component Type                                    | Location                         |
+| -------: | ------------------------------------------------- | -------------------------------- |
+|      ⬆ 1 | Project-Local Overrides                           | `.specify/templates/overrides/`  |
+|        2 | Presets — Customize core & extensions             | `.specify/presets/templates/`    |
+|        3 | Extensions — Add new capabilities                 | `.specify/extensions/templates/` |
+|      ⬇ 4 | Spec Kit Core — Built-in SDD commands & templates | `.specify/templates/`            |
+
+- **Templates** are resolved at **runtime** — Spec Kit walks the stack top-down and uses the first match.
+- Project-local overrides (`.specify/templates/overrides/`) let you make one-off adjustments for a single project without creating a full preset.
+- **Extension/preset commands** are applied at **install time** — when you run `specify extension add` or `specify preset add`, command files are written into agent directories (e.g., `.claude/commands/`).
+- If multiple presets or extensions provide the same command, the highest-priority version wins. On removal, the next-highest-priority version is restored automatically.
+- If no overrides or customizations exist, Spec Kit uses its core defaults.
+
+### Extensions — Add New Capabilities
+
+Use **extensions** when you need functionality that goes beyond Spec Kit's core. Extensions introduce new commands and templates — for example, adding domain-specific workflows that are not covered by the built-in SDD commands, integrating with external tools, or adding entirely new development phases. They expand *what Spec Kit can do*.
+
+```bash
+# Search available extensions
+specify extension search
+
+# Install an extension
+specify extension add <extension-name>
+```
+
+For example, extensions could add Jira integration, post-implementation code review, V-Model test traceability, or project health diagnostics.
+
+See the [Extensions README](./extensions/README.md) for the full guide and how to build and publish your own. Browse the [community extensions](#-community-extensions) above for what's available.
+
+### Presets — Customize Existing Workflows
+
+Use **presets** when you want to change *how* Spec Kit works without adding new capabilities. Presets override the templates and commands that ship with the core *and* with installed extensions — for example, enforcing a compliance-oriented spec format, using domain-specific terminology, or applying organizational standards to plans and tasks. They customize the artifacts and instructions that Spec Kit and its extensions produce.
+
+```bash
+# Search available presets
+specify preset search
+
+# Install a preset
+specify preset add <preset-name>
+```
+
+For example, presets could restructure spec templates to require regulatory traceability, adapt the workflow to fit the methodology you use (e.g., Agile, Kanban, Waterfall, jobs-to-be-done, or domain-driven design), add mandatory security review gates to plans, enforce test-first task ordering, or localize the entire workflow to a different language. The [pirate-speak demo](https://github.com/mnriem/spec-kit-pirate-speak-preset-demo) shows just how deep the customization can go. Multiple presets can be stacked with priority ordering.
+
+See the [Presets README](./presets/README.md) for the full guide, including resolution order, priority, and how to create your own.
+
+### When to Use Which
+
+| Goal | Use |
+| --- | --- |
+| Add a brand-new command or workflow | Extension |
+| Customize the format of specs, plans, or tasks | Preset |
+| Integrate an external tool or service | Extension |
+| Enforce organizational or regulatory standards | Preset |
+| Ship reusable domain-specific templates | Either — presets for template overrides, extensions for templates bundled with new commands |
+
+## 📚 Core Philosophy
 
 Spec-Driven Development is a structured process that emphasizes:
 
-- **Intent-driven development** where specifications define the "_what_" before the "_how_"
+- **Intent-driven development** where specifications define the "*what*" before the "*how*"
 - **Rich specification creation** using guardrails and organizational principles
 - **Multi-step refinement** rather than one-shot code generation from prompts
 - **Heavy reliance** on advanced AI model capabilities for specification interpretation

+# Testing Guide
+
+This document is the detailed testing companion to [`CONTRIBUTING.md`](./CONTRIBUTING.md).
+
+Use it for three things:
+
+1. running quick automated checks before manual testing,
+2. manually testing affected slash commands through an AI agent, and
+3. capturing the results in a PR-friendly format.
+
+Any change that affects a slash command's behavior requires manually testing that command through an AI agent and submitting results with the PR.
+
+## Recommended order
+
+1. **Sync your environment** — install the project and test dependencies.
+2. **Run focused automated checks** — especially for packaging, scaffolding, agent config, and generated-file changes.
+3. **Run manual agent tests** — for any affected slash commands.
+4. **Paste results into your PR** — include both command-selection reasoning and manual test results.
+
+## Quick automated checks
+
+Run these before manual testing when your change affects packaging, scaffolding, templates, release artifacts, or agent wiring.
+
+### Environment setup
+
+```bash
+cd <spec-kit-repo>
+uv sync --extra test
+source .venv/bin/activate  # On Windows (CMD): .venv\Scripts\activate  |  (PowerShell): .venv\Scripts\Activate.ps1
+```
+
+### Generated package structure and content
+
+```bash
+uv run python -m pytest tests/test_core_pack_scaffold.py -q
+```
+
+This validates the generated files that CI-style packaging depends on, including directory layout, file names, frontmatter/TOML validity, placeholder replacement, `.specify/` path rewrites, and parity with `create-release-packages.sh`.
+
+### Agent configuration and release wiring consistency
+
+```bash
+uv run python -m pytest tests/test_agent_config_consistency.py -q
+```
+
+Run this when you change agent metadata, release scripts, context update scripts, or artifact naming.
+
+### Optional single-agent packaging spot check
+
+```bash
+AGENTS=copilot SCRIPTS=sh ./.github/workflows/scripts/create-release-packages.sh v1.0.0
+```
+
+Inspect `.genreleases/sdd-copilot-package-sh/` and the matching ZIP in `.genreleases/` when you want to review the exact packaged output for one agent/script combination.
+
+## Manual testing process
+
+1. **Identify affected commands** — use the [prompt below](#determining-which-tests-to-run) to have your agent analyze your changed files and determine which commands need testing.
+2. **Set up a test project** — scaffold from your local branch (see [Setup](#setup)).
+3. **Run each affected command** — invoke it in your agent, verify it completes successfully, and confirm it produces the expected output (files created, scripts executed, artifacts populated).
+4. **Run prerequisites first** — commands that depend on earlier commands (e.g., `/speckit.tasks` requires `/speckit.plan` which requires `/speckit.specify`) must be run in order.
+5. **Report results** — paste the [reporting template](#reporting-results) into your PR with pass/fail for each command tested.
+
+## Setup
+
+```bash
+# Install the project and test dependencies from your local branch
+cd <spec-kit-repo>
+uv sync --extra test
+source .venv/bin/activate  # On Windows (CMD): .venv\Scripts\activate  |  (PowerShell): .venv\Scripts\Activate.ps1
+uv pip install -e .
+# Ensure the `specify` binary in this environment points at your working tree so the agent runs the branch you're testing.
+
+# Initialize a test project using your local changes
+uv run specify init /tmp/speckit-test --ai <agent> --offline
+cd /tmp/speckit-test
+
+# Open in your agent
+```
+
+If you are testing the packaged output rather than the live source tree, create a local release package first as described in [`CONTRIBUTING.md`](./CONTRIBUTING.md).
+
+## Reporting results
+
+Paste this into your PR:
+
+~~~markdown
+## Manual test results
+
+**Agent**: [e.g., GitHub Copilot in VS Code]  |  **OS/Shell**: [e.g., macOS/zsh]
+
+| Command tested | Notes |
+|----------------|-------|
+| `/speckit.command` | |
+~~~
+
+## Determining which tests to run
+
+Copy this prompt into your agent. Include the agent's response (selected tests plus a brief explanation of the mapping) in your PR.
+
+~~~text
+Read TESTING.md, then run `git diff --name-only main` to get my changed files.
+For each changed file, determine which slash commands it affects by reading
+the command templates in templates/commands/ to understand what each command
+invokes. Use these mapping rules:
+
+- templates/commands/X.md → the command it defines
+- scripts/bash/Y.sh or scripts/powershell/Y.ps1 → every command that invokes that script (grep templates/commands/ for the script name). Also check transitive dependencies: if the changed script is sourced by other scripts (e.g., common.sh is sourced by create-new-feature.sh, check-prerequisites.sh, setup-plan.sh, update-agent-context.sh), then every command invoking those downstream scripts is also affected
+- templates/Z-template.md → every command that consumes that template during execution
+- src/specify_cli/*.py → CLI commands (`specify init`, `specify check`, `specify extension *`, `specify preset *`); test the affected CLI command and, for init/scaffolding changes, at minimum test /speckit.specify
+- extensions/X/commands/* → the extension command it defines
+- extensions/X/scripts/* → every extension command that invokes that script
+- extensions/X/extension.yml or config-template.yml → every command in that extension. Also check if the manifest defines hooks (look for `hooks:` entries like `before_specify`, `after_implement`, etc.) — if so, the core commands those hooks attach to are also affected
+- presets/*/* → test preset scaffolding via `specify init` with the preset
+- pyproject.toml → packaging/bundling; test `specify init` and verify bundled assets
+
+Include prerequisite tests (e.g., T5 requires T3 requires T1).
+
+Output in this format:
+
+### Test selection reasoning
+
+| Changed file | Affects | Test | Why |
+|---|---|---|---|
+| (path) | (command) | T# | (reason) |
+
+### Required tests
+
+Number each test sequentially (T1, T2, ...). List prerequisite tests first.
+
+- T1: /speckit.command — (reason)
+- T2: /speckit.command — (reason)

+
+*Build high-quality software faster.*
+
+**An effort to allow organizations to focus on product scenarios rather than writing undifferentiated code with the help of Spec-Driven Development.**
+
+## What is Spec-Driven Development?
+
+Spec-Driven Development **flips the script** on traditional software development. For decades, code has been king — specifications were just scaffolding we built and discarded once the "real work" of coding began. Spec-Driven Development changes this: **specifications become executable**, directly generating working implementations rather than just guiding them.

+- [Installation Guide](installation.md)
+- [Quick Start Guide](quickstart.md)
+- [Upgrade Guide](upgrade.md)
+- [Local Development](local-development.md)
+
+## Core Philosophy
+
+Spec-Driven Development is a structured process that emphasizes:
+
+- **Intent-driven development** where specifications define the "*what*" before the "*how*"
+- **Rich specification creation** using guardrails and organizational principles
+- **Multi-step refinement** rather than one-shot code generation from prompts
+- **Heavy reliance** on advanced AI model capabilities for specification interpretation
+
+## Development Phases
+
+| Phase | Focus | Key Activities |

+# Installation Guide
+
+## Prerequisites
+
+- **Linux/macOS** (or Windows; PowerShell scripts now supported without WSL)
+- AI coding agent: [Claude Code](https://www.anthropic.com/claude-code), [GitHub Copilot](https://code.visualstudio.com/), [Codebuddy CLI](https://www.codebuddy.ai/cli), [Gemini CLI](https://github.com/google-gemini/gemini-cli), or [Pi Coding Agent](https://pi.dev)
+- [uv](https://docs.astral.sh/uv/) for package management
+- [Python 3.11+](https://www.python.org/downloads/)
+- [Git](https://git-scm.com/downloads)
+
+## Installation
+
+### Initialize a New Project
+
+The easiest way to get started is to initialize a new project. Pin a specific release tag for stability (check [Releases](https://github.com/github/spec-kit/releases) for the latest):
+
+```bash
+# Install from a specific stable release (recommended — replace vX.Y.Z with the latest tag)
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init <PROJECT_NAME>
+
+# Or install latest from main (may include unreleased changes)
+uvx --from git+https://github.com/github/spec-kit.git specify init <PROJECT_NAME>
+```
+
+Or initialize in the current directory:
+
+```bash
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init .
+# or use the --here flag
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init --here
+```
+
+### Specify AI Agent
+
+You can proactively specify your AI agent during initialization:
+
+```bash
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init <project_name> --ai claude
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init <project_name> --ai gemini
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init <project_name> --ai copilot
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init <project_name> --ai codebuddy
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init <project_name> --ai pi
+```
+
+### Specify Script Type (Shell vs PowerShell)
+
+All automation scripts now have both Bash (`.sh`) and PowerShell (`.ps1`) variants.
+
+Auto behavior:
+
+- Windows default: `ps`
+- Other OS default: `sh`
+- Interactive mode: you'll be prompted unless you pass `--script`
+
+Force a specific script type:
+
+```bash
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init <project_name> --script sh
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init <project_name> --script ps
+```
+
+### Ignore Agent Tools Check
+
+If you prefer to get the templates without checking for the right tools:
+
+```bash
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init <project_name> --ai claude --ignore-agent-tools
+```
+
+## Verification
+
+After initialization, you should see the following commands available in your AI agent:
+
+- `/speckit.specify` - Create specifications
+- `/speckit.plan` - Generate implementation plans  
+- `/speckit.tasks` - Break down into actionable tasks
+
+The `.specify/scripts` directory will contain both `.sh` and `.ps1` scripts.
+
+## Troubleshooting
+
+### Enterprise / Air-Gapped Installation
+
+If your environment blocks access to PyPI (you see 403 errors when running `uv tool install` or `pip install`), you can create a portable wheel bundle on a connected machine and transfer it to the air-gapped target.
+
+**Step 1: Build the wheel on a connected machine (same OS and Python version as the target)**
+
+```bash
+# Clone the repository
+git clone https://github.com/github/spec-kit.git
+cd spec-kit
+
+# Build the wheel
+pip install build
+python -m build --wheel --outdir dist/
+
+# Download the wheel and all its runtime dependencies
+pip download -d dist/ dist/specify_cli-*.whl
+```
+
+> **Important:** `pip download` resolves platform-specific wheels (e.g., PyYAML includes native extensions). You must run this step on a machine with the **same OS and Python version** as the air-gapped target. If you need to support multiple platforms, repeat this step on each target OS (Linux, macOS, Windows) and Python version.
+
+**Step 2: Transfer the `dist/` directory to the air-gapped machine**
+
+Copy the entire `dist/` directory (which contains the `specify-cli` wheel and all dependency wheels) to the target machine via USB, network share, or other approved transfer method.
+
+**Step 3: Install on the air-gapped machine**
+
+```bash
+pip install --no-index --find-links=./dist specify-cli
+```
+
+**Step 4: Initialize a project (no network required)**
+
+```bash
+# Initialize a project — no GitHub access needed
+specify init my-project --ai claude --offline
+```
+
+The `--offline` flag tells the CLI to use the templates, commands, and scripts bundled inside the wheel instead of downloading from GitHub.
+
+> **Deprecation notice:** Starting with v0.6.0, `specify init` will use bundled assets by default and the `--offline` flag will be removed. The GitHub download path will be retired because bundled assets eliminate the need for network access, avoid proxy/firewall issues, and guarantee that templates always match the installed CLI version. No action will be needed — `specify init` will simply work without network access out of the box.
+
+> **Note:** Python 3.11+ is required.
+
+> **Windows note:** Offline scaffolding requires PowerShell 7+ (`pwsh`), not Windows PowerShell 5.x (`powershell.exe`). Install from https://aka.ms/powershell.
+
+### Git Credential Manager on Linux
+
+If you're having issues with Git authentication on Linux, you can install Git Credential Manager:
+
+```bash
+#!/usr/bin/env bash
+set -e
+echo "Downloading Git Credential Manager v2.6.1..."
+wget https://github.com/git-ecosystem/git-credential-manager/releases/download/v2.6.1/gcm-linux_amd64.2.6.1.deb
+echo "Installing Git Credential Manager..."
+sudo dpkg -i gcm-linux_amd64.2.6.1.deb
+echo "Configuring Git to use GCM..."
+git config --global credential.helper manager
+echo "Cleaning up..."
+rm gcm-linux_amd64.2.6.1.deb
+```

+# Local Development Guide
+
+This guide shows how to iterate on the `specify` CLI locally without publishing a release or committing to `main` first.
+
+> Scripts now have both Bash (`.sh`) and PowerShell (`.ps1`) variants. The CLI auto-selects based on OS unless you pass `--script sh|ps`.
+
+## 1. Clone and Switch Branches
+
+```bash
+git clone https://github.com/github/spec-kit.git
+cd spec-kit
+# Work on a feature branch
+git checkout -b your-feature-branch
+```
+
+## 2. Run the CLI Directly (Fastest Feedback)
+
+You can execute the CLI via the module entrypoint without installing anything:
+
+```bash
+# From repo root
+python -m src.specify_cli --help
+python -m src.specify_cli init demo-project --ai claude --ignore-agent-tools --script sh
+```
+
+If you prefer invoking the script file style (uses shebang):
+
+```bash
+python src/specify_cli/__init__.py init demo-project --script ps
+```
+
+## 3. Use Editable Install (Isolated Environment)
+
+Create an isolated environment using `uv` so dependencies resolve exactly like end users get them:
+
+```bash
+# Create & activate virtual env (uv auto-manages .venv)
+uv venv
+source .venv/bin/activate  # or on Windows PowerShell: .venv\Scripts\Activate.ps1
+
+# Install project in editable mode
+uv pip install -e .
+
+# Now 'specify' entrypoint is available
+specify --help
+```
+
+Re-running after code edits requires no reinstall because of editable mode.
+
+## 4. Invoke with uvx Directly From Git (Current Branch)
+
+`uvx` can run from a local path (or a Git ref) to simulate user flows:
+
+```bash
+uvx --from . specify init demo-uvx --ai copilot --ignore-agent-tools --script sh
+```
+
+You can also point uvx at a specific branch without merging:
+
+```bash
+# Push your working branch first
+git push origin your-feature-branch
+uvx --from git+https://github.com/github/spec-kit.git@your-feature-branch specify init demo-branch-test --script ps
+```
+
+### 4a. Absolute Path uvx (Run From Anywhere)
+
+If you're in another directory, use an absolute path instead of `.`:
+
+```bash
+uvx --from /mnt/c/GitHub/spec-kit specify --help
+uvx --from /mnt/c/GitHub/spec-kit specify init demo-anywhere --ai copilot --ignore-agent-tools --script sh
+```
+
+Set an environment variable for convenience:
+
+```bash
+export SPEC_KIT_SRC=/mnt/c/GitHub/spec-kit
+uvx --from "$SPEC_KIT_SRC" specify init demo-env --ai copilot --ignore-agent-tools --script ps
+```
+
+(Optional) Define a shell function:
+
+```bash
+specify-dev() { uvx --from /mnt/c/GitHub/spec-kit specify "$@"; }
+# Then
+specify-dev --help
+```
+
+## 5. Testing Script Permission Logic
+
+After running an `init`, check that shell scripts are executable on POSIX systems:
+
+```bash
+ls -l scripts | grep .sh
+# Expect owner execute bit (e.g. -rwxr-xr-x)
+```
+
+On Windows you will instead use the `.ps1` scripts (no chmod needed).
+
+## 6. Run Lint / Basic Checks (Add Your Own)
+
+Currently no enforced lint config is bundled, but you can quickly sanity check importability:
+
+```bash
+python -c "import specify_cli; print('Import OK')"
+```
+
+## 7. Build a Wheel Locally (Optional)
+
+Validate packaging before publishing:
+
+```bash
+uv build
+ls dist/
+```
+
+Install the built artifact into a fresh throwaway environment if needed.
+
+## 8. Using a Temporary Workspace
+
+When testing `init --here` in a dirty directory, create a temp workspace:
+
+```bash
+mkdir /tmp/spec-test && cd /tmp/spec-test
+python -m src.specify_cli init --here --ai claude --ignore-agent-tools --script sh  # if repo copied here
+```
+
+Or copy only the modified CLI portion if you want a lighter sandbox.
+
+## 9. Debug Network / TLS Skips
+
+If you need to bypass TLS validation while experimenting:
+
+```bash
+specify check --skip-tls
+specify init demo --skip-tls --ai gemini --ignore-agent-tools --script ps
+```
+
+(Use only for local experimentation.)
+
+## 10. Rapid Edit Loop Summary
+
+| Action | Command |
+|--------|---------|
+| Run CLI directly | `python -m src.specify_cli --help` |
+| Editable install | `uv pip install -e .` then `specify ...` |
+| Local uvx run (repo root) | `uvx --from . specify ...` |
+| Local uvx run (abs path) | `uvx --from /mnt/c/GitHub/spec-kit specify ...` |
+| Git branch uvx | `uvx --from git+URL@branch specify ...` |
+| Build wheel | `uv build` |
+
+## 11. Cleaning Up
+
+Remove build artifacts / virtual env quickly:
+
+```bash
+rm -rf .venv dist build *.egg-info
+```
+
+## 12. Common Issues
+
+| Symptom | Fix |
+|---------|-----|
+| `ModuleNotFoundError: typer` | Run `uv pip install -e .` |
+| Scripts not executable (Linux) | Re-run init or `chmod +x scripts/*.sh` |
+| Git step skipped | You passed `--no-git` or Git not installed |
+| Wrong script type downloaded | Pass `--script sh` or `--script ps` explicitly |
+| TLS errors on corporate network | Try `--skip-tls` (not for production) |
+
+## 13. Next Steps
+
+- Update docs and run through Quick Start using your modified CLI
+- Open a PR when satisfied
+- (Optional) Tag a release once changes land in `main`

+# Quick Start Guide
+
+This guide will help you get started with Spec-Driven Development using Spec Kit.
+
+> [!NOTE]
+> All automation scripts now provide both Bash (`.sh`) and PowerShell (`.ps1`) variants. The `specify` CLI auto-selects based on OS unless you pass `--script sh|ps`.
+
+## The 6-Step Process
+
+> [!TIP]
+> **Context Awareness**: Spec Kit commands automatically detect the active feature based on your current Git branch (e.g., `001-feature-name`). To switch between different specifications, simply switch Git branches.
+
+### Step 1: Install Specify
+
+**In your terminal**, run the `specify` CLI command to initialize your project:
+
+```bash
+# Create a new project directory
+uvx --from git+https://github.com/github/spec-kit.git specify init <PROJECT_NAME>
+
+# OR initialize in the current directory
+uvx --from git+https://github.com/github/spec-kit.git specify init .
+```
+
+Pick script type explicitly (optional):
+
+```bash
+uvx --from git+https://github.com/github/spec-kit.git specify init <PROJECT_NAME> --script ps  # Force PowerShell
+uvx --from git+https://github.com/github/spec-kit.git specify init <PROJECT_NAME> --script sh  # Force POSIX shell
+```
+
+### Step 2: Define Your Constitution
+
+**In your AI Agent's chat interface**, use the `/speckit.constitution` slash command to establish the core rules and principles for your project. You should provide your project's specific principles as arguments.
+
+```markdown
+/speckit.constitution This project follows a "Library-First" approach. All features must be implemented as standalone libraries first. We use TDD strictly. We prefer functional programming patterns.
+```
+
+### Step 3: Create the Spec
+
+**In the chat**, use the `/speckit.specify` slash command to describe what you want to build. Focus on the **what** and **why**, not the tech stack.
+
+```markdown
+/speckit.specify Build an application that can help me organize my photos in separate photo albums. Albums are grouped by date and can be re-organized by dragging and dropping on the main page. Albums are never in other nested albums. Within each album, photos are previewed in a tile-like interface.
+```
+
+### Step 4: Refine the Spec
+
+**In the chat**, use the `/speckit.clarify` slash command to identify and resolve ambiguities in your specification. You can provide specific focus areas as arguments.
+
+```bash
+/speckit.clarify Focus on security and performance requirements.
+```
+
+### Step 5: Create a Technical Implementation Plan
+
+**In the chat**, use the `/speckit.plan` slash command to provide your tech stack and architecture choices.
+
+```markdown
+/speckit.plan The application uses Vite with minimal number of libraries. Use vanilla HTML, CSS, and JavaScript as much as possible. Images are not uploaded anywhere and metadata is stored in a local SQLite database.
+```
+
+### Step 6: Break Down and Implement
+
+**In the chat**, use the `/speckit.tasks` slash command to create an actionable task list.
+
+```markdown
+/speckit.tasks
+```
+
+Optionally, validate the plan with `/speckit.analyze`:
+
+```markdown
+/speckit.analyze
+```
+
+Then, use the `/speckit.implement` slash command to execute the plan.
+
+```markdown
+/speckit.implement
+```
+
+> [!TIP]
+> **Phased Implementation**: For complex projects, implement in phases to avoid overwhelming the agent's context. Start with core functionality, validate it works, then add features incrementally.
+
+## Detailed Example: Building Taskify
+
+Here's a complete example of building a team productivity platform:
+
+### Step 1: Define Constitution
+
+Initialize the project's constitution to set ground rules:
+
+```markdown
+/speckit.constitution Taskify is a "Security-First" application. All user inputs must be validated. We use a microservices architecture. Code must be fully documented.
+```
+
+### Step 2: Define Requirements with `/speckit.specify`
+
+```text
+Develop Taskify, a team productivity platform. It should allow users to create projects, add team members,
+assign tasks, comment and move tasks between boards in Kanban style. In this initial phase for this feature,
+let's call it "Create Taskify," let's have multiple users but the users will be declared ahead of time, predefined.
+I want five users in two different categories, one product manager and four engineers. Let's create three
+different sample projects. Let's have the standard Kanban columns for the status of each task, such as "To Do,"
+"In Progress," "In Review," and "Done." There will be no login for this application as this is just the very
+first testing thing to ensure that our basic features are set up.
+```
+
+### Step 3: Refine the Specification
+
+Use the `/speckit.clarify` command to interactively resolve any ambiguities in your specification. You can also provide specific details you want to ensure are included.
+
+```bash
+/speckit.clarify I want to clarify the task card details. For each task in the UI for a task card, you should be able to change the current status of the task between the different columns in the Kanban work board. You should be able to leave an unlimited number of comments for a particular card. You should be able to, from that task card, assign one of the valid users.
+```
+
+You can continue to refine the spec with more details using `/speckit.clarify`:
+
+```bash
+/speckit.clarify When you first launch Taskify, it's going to give you a list of the five users to pick from. There will be no password required. When you click on a user, you go into the main view, which displays the list of projects. When you click on a project, you open the Kanban board for that project. You're going to see the columns. You'll be able to drag and drop cards back and forth between different columns. You will see any cards that are assigned to you, the currently logged in user, in a different color from all the other ones, so you can quickly see yours. You can edit any comments that you make, but you can't edit comments that other people made. You can delete any comments that you made, but you can't delete comments anybody else made.
+```
+
+### Step 4: Validate the Spec
+
+Validate the specification checklist using the `/speckit.checklist` command:
+
+```bash
+/speckit.checklist
+```
+
+### Step 5: Generate Technical Plan with `/speckit.plan`
+
+Be specific about your tech stack and technical requirements:
+
+```bash
+/speckit.plan We are going to generate this using .NET Aspire, using Postgres as the database. The frontend should use Blazor server with drag-and-drop task boards, real-time updates. There should be a REST API created with a projects API, tasks API, and a notifications API.
+```
+
+### Step 6: Define Tasks
+
+Generate an actionable task list using the `/speckit.tasks` command:
+
+```bash
+/speckit.tasks
+```
+
+### Step 7: Validate and Implement
+
+Have your AI agent audit the implementation plan using `/speckit.analyze`:
+
+```bash
+/speckit.analyze
+```
+
+Finally, implement the solution:
+
+```bash
+/speckit.implement
+```
+
+> [!TIP]
+> **Phased Implementation**: For large projects like Taskify, consider implementing in phases (e.g., Phase 1: Basic project/task structure, Phase 2: Kanban functionality, Phase 3: Comments and assignments). This prevents context saturation and allows for validation at each stage.
+
+## Key Principles
+
+- **Be explicit** about what you're building and why
+- **Don't focus on tech stack** during specification phase
+- **Iterate and refine** your specifications before implementation
+- **Validate** the plan before coding begins
+- **Let the AI agent handle** the implementation details
+
+## Next Steps
+
+- Read the [complete methodology](https://github.com/github/spec-kit/blob/main/spec-driven.md) for in-depth guidance

+# Upgrade Guide
+
+> You have Spec Kit installed and want to upgrade to the latest version to get new features, bug fixes, or updated slash commands. This guide covers both upgrading the CLI tool and updating your project files.
+
+---
+
+## Quick Reference
+
+| What to Upgrade | Command | When to Use |
+|----------------|---------|-------------|
+| **CLI Tool Only** | `uv tool install specify-cli --force --from git+https://github.com/github/spec-kit.git@vX.Y.Z` | Get latest CLI features without touching project files |
+| **Project Files** | `specify init --here --force --ai <your-agent>` | Update slash commands, templates, and scripts in your project |
+| **Both** | Run CLI upgrade, then project update | Recommended for major version updates |
+
+---
+
+## Part 1: Upgrade the CLI Tool
+
+The CLI tool (`specify`) is separate from your project files. Upgrade it to get the latest features and bug fixes.
+
+### If you installed with `uv tool install`
+
+Upgrade to a specific release (check [Releases](https://github.com/github/spec-kit/releases) for the latest tag):
+
+```bash
+uv tool install specify-cli --force --from git+https://github.com/github/spec-kit.git@vX.Y.Z
+```
+
+### If you use one-shot `uvx` commands
+
+Specify the desired release tag:
+
+```bash
+uvx --from git+https://github.com/github/spec-kit.git@vX.Y.Z specify init --here --ai copilot
+```
+
+### Verify the upgrade
+
+```bash
+specify check
+```
+
+This shows installed tools and confirms the CLI is working.
+
+---
+
+## Part 2: Updating Project Files
+
+When Spec Kit releases new features (like new slash commands or updated templates), you need to refresh your project's Spec Kit files.
+
+### What gets updated?
+
+Running `specify init --here --force` will update:
+
+- ✅ **Slash command files** (`.claude/commands/`, `.github/prompts/`, etc.)
+- ✅ **Script files** (`.specify/scripts/`)
+- ✅ **Template files** (`.specify/templates/`)
+- ✅ **Shared memory files** (`.specify/memory/`) - **⚠️ See warnings below**
+
+### What stays safe?
+
+These files are **never touched** by the upgrade—the template packages don't even contain them:
+
+- ✅ **Your specifications** (`specs/001-my-feature/spec.md`, etc.) - **CONFIRMED SAFE**
+- ✅ **Your implementation plans** (`specs/001-my-feature/plan.md`, `tasks.md`, etc.) - **CONFIRMED SAFE**
+- ✅ **Your source code** - **CONFIRMED SAFE**
+- ✅ **Your git history** - **CONFIRMED SAFE**
+
+The `specs/` directory is completely excluded from template packages and will never be modified during upgrades.
+
+### Update command
+
+Run this inside your project directory:
+
+```bash
+specify init --here --force --ai <your-agent>
+```
+
+Replace `<your-agent>` with your AI assistant. Refer to this list of [Supported AI Agents](../README.md#-supported-ai-agents)
+
+**Example:**
+
+```bash
+specify init --here --force --ai copilot
+```
+
+### Understanding the `--force` flag
+
+Without `--force`, the CLI warns you and asks for confirmation:
+
+```text
+Warning: Current directory is not empty (25 items)
+Template files will be merged with existing content and may overwrite existing files
+Proceed? [y/N]
+```
+
+With `--force`, it skips the confirmation and proceeds immediately.
+
+**Important: Your `specs/` directory is always safe.** The `--force` flag only affects template files (commands, scripts, templates, memory). Your feature specifications, plans, and tasks in `specs/` are never included in upgrade packages and cannot be overwritten.
+
+---
+
+## ⚠️ Important Warnings
+
+### 1. Constitution file will be overwritten
+
+**Known issue:** `specify init --here --force` currently overwrites `.specify/memory/constitution.md` with the default template, erasing any customizations you made.
+
+**Workaround:**
+
+```bash
+# 1. Back up your constitution before upgrading
+cp .specify/memory/constitution.md .specify/memory/constitution-backup.md
+
+# 2. Run the upgrade
+specify init --here --force --ai copilot
+
+# 3. Restore your customized constitution
+mv .specify/memory/constitution-backup.md .specify/memory/constitution.md
+```
+
+Or use git to restore it:
+
+```bash
+# After upgrade, restore from git history
+git restore .specify/memory/constitution.md
+```
+
+### 2. Custom template modifications
+
+If you customized any templates in `.specify/templates/`, the upgrade will overwrite them. Back them up first:
+
+```bash
+# Back up custom templates
+cp -r .specify/templates .specify/templates-backup
+
+# After upgrade, merge your changes back manually
+```
+
+### 3. Duplicate slash commands (IDE-based agents)
+
+Some IDE-based agents (like Kilo Code, Windsurf) may show **duplicate slash commands** after upgrading—both old and new versions appear.
+
+**Solution:** Manually delete the old command files from your agent's folder.
+
+**Example for Kilo Code:**
+
+```bash
+# Navigate to the agent's commands folder
+cd .kilocode/rules/
+
+# List files and identify duplicates
+ls -la
+
+# Delete old versions (example filenames - yours may differ)
+rm speckit.specify-old.md
+rm speckit.plan-v1.md
+```
+
+Restart your IDE to refresh the command list.
+
+---
+
+## Common Scenarios
+
+### Scenario 1: "I just want new slash commands"
+
+```bash
+# Upgrade CLI (if using persistent install)
+uv tool install specify-cli --force --from git+https://github.com/github/spec-kit.git
+
+# Update project files to get new commands
+specify init --here --force --ai copilot
+
+# Restore your constitution if customized
+git restore .specify/memory/constitution.md
+```
+
+### Scenario 2: "I customized templates and constitution"
+
+```bash
+# 1. Back up customizations
+cp .specify/memory/constitution.md /tmp/constitution-backup.md
+cp -r .specify/templates /tmp/templates-backup
+
+# 2. Upgrade CLI
+uv tool install specify-cli --force --from git+https://github.com/github/spec-kit.git
+
+# 3. Update project
+specify init --here --force --ai copilot
+
+# 4. Restore customizations
+mv /tmp/constitution-backup.md .specify/memory/constitution.md
+# Manually merge template changes if needed
+```
+
+### Scenario 3: "I see duplicate slash commands in my IDE"
+
+This happens with IDE-based agents (Kilo Code, Windsurf, Roo Code, etc.).
+
+```bash
+# Find the agent folder (example: .kilocode/rules/)
+cd .kilocode/rules/
+
+# List all files
+ls -la
+
+# Delete old command files
+rm speckit.old-command-name.md
+
+# Restart your IDE
+```
+
+### Scenario 4: "I'm working on a project without Git"
+
+If you initialized your project with `--no-git`, you can still upgrade:
+
+```bash
+# Manually back up files you customized
+cp .specify/memory/constitution.md /tmp/constitution-backup.md
+
+# Run upgrade
+specify init --here --force --ai copilot --no-git
+
+# Restore customizations
+mv /tmp/constitution-backup.md .specify/memory/constitution.md
+```
+
+The `--no-git` flag skips git initialization but doesn't affect file updates.
+
+---
+
+## Using `--no-git` Flag
+
+The `--no-git` flag tells Spec Kit to **skip git repository initialization**. This is useful when:
+
+- You manage version control differently (Mercurial, SVN, etc.)
+- Your project is part of a larger monorepo with existing git setup
+- You're experimenting and don't want version control yet
+
+**During initial setup:**
+
+```bash
+specify init my-project --ai copilot --no-git
+```
+
+**During upgrade:**
+
+```bash
+specify init --here --force --ai copilot --no-git
+```
+
+### What `--no-git` does NOT do
+
+❌ Does NOT prevent file updates
+❌ Does NOT skip slash command installation
+❌ Does NOT affect template merging
+
+It **only** skips running `git init` and creating the initial commit.
+
+### Working without Git
+
+If you use `--no-git`, you'll need to manage feature directories manually:
+
+**Set the `SPECIFY_FEATURE` environment variable** before using planning commands:
+
+```bash
+# Bash/Zsh
+export SPECIFY_FEATURE="001-my-feature"
+
+# PowerShell
+$env:SPECIFY_FEATURE = "001-my-feature"
+```
+
+This tells Spec Kit which feature directory to use when creating specs, plans, and tasks.
+
+**Why this matters:** Without git, Spec Kit can't detect your current branch name to determine the active feature. The environment variable provides that context manually.
+
+---
+
+## Troubleshooting
+
+### "Slash commands not showing up after upgrade"
+
+**Cause:** Agent didn't reload the command files.
+
+**Fix:**
+
+1. **Restart your IDE/editor** completely (not just reload window)
+2. **For CLI-based agents**, verify files exist:
+
+   ```bash
+   ls -la .claude/commands/      # Claude Code
+   ls -la .gemini/commands/      # Gemini
+   ls -la .cursor/skills/      # Cursor
+   ls -la .pi/prompts/           # Pi Coding Agent
+   ```
+
+3. **Check agent-specific setup:**
+   - Codex requires `CODEX_HOME` environment variable
+   - Some agents need workspace restart or cache clearing
+
+### "I lost my constitution customizations"
+
+**Fix:** Restore from git or backup:
+
+```bash
+# If you committed before upgrading
+git restore .specify/memory/constitution.md
+
+# If you backed up manually
+cp /tmp/constitution-backup.md .specify/memory/constitution.md
+```
+
+**Prevention:** Always commit or back up `constitution.md` before upgrading.
+
+### "Warning: Current directory is not empty"
+
+**Full warning message:**
+
+```text
+Warning: Current directory is not empty (25 items)
+Template files will be merged with existing content and may overwrite existing files
+Do you want to continue? [y/N]
+```
+
+**What this means:**
+
+This warning appears when you run `specify init --here` (or `specify init .`) in a directory that already has files. It's telling you:
+
+1. **The directory has existing content** - In the example, 25 files/folders
+2. **Files will be merged** - New template files will be added alongside your existing files
+3. **Some files may be overwritten** - If you already have Spec Kit files (`.claude/`, `.specify/`, etc.), they'll be replaced with the new versions
+
+**What gets overwritten:**
+
+Only Spec Kit infrastructure files:
+
+- Agent command files (`.claude/commands/`, `.github/prompts/`, etc.)
+- Scripts in `.specify/scripts/`
+- Templates in `.specify/templates/`
+- Memory files in `.specify/memory/` (including constitution)
+
+**What stays untouched:**
+
+- Your `specs/` directory (specifications, plans, tasks)
+- Your source code files
+- Your `.git/` directory and git history
+- Any other files not part of Spec Kit templates
+
+**How to respond:**
+
+- **Type `y` and press Enter** - Proceed with the merge (recommended if upgrading)
+- **Type `n` and press Enter** - Cancel the operation
+- **Use `--force` flag** - Skip this confirmation entirely:
+
+  ```bash
+  specify init --here --force --ai copilot
+  ```
+
+**When you see this warning:**
+
+- ✅ **Expected** when upgrading an existing Spec Kit project
+- ✅ **Expected** when adding Spec Kit to an existing codebase
+- ⚠️ **Unexpected** if you thought you were creating a new project in an empty directory
+
+**Prevention tip:** Before upgrading, commit or back up your `.specify/memory/constitution.md` if you customized it.
+
+### "CLI upgrade doesn't seem to work"
+
+Verify the installation:
+
+```bash
+# Check installed tools
+uv tool list
+
+# Should show specify-cli
+
+# Verify path
+which specify
+
+# Should point to the uv tool installation directory
+```
+
+If not found, reinstall:
+
+```bash
+uv tool uninstall specify-cli
+uv tool install specify-cli --from git+https://github.com/github/spec-kit.git
+```
+
+### "Do I need to run specify every time I open my project?"
+
+**Short answer:** No, you only run `specify init` once per project (or when upgrading).
+
+**Explanation:**
+
+The `specify` CLI tool is used for:
+
+- **Initial setup:** `specify init` to bootstrap Spec Kit in your project
+- **Upgrades:** `specify init --here --force` to update templates and commands
+- **Diagnostics:** `specify check` to verify tool installation
+
+Once you've run `specify init`, the slash commands (like `/speckit.specify`, `/speckit.plan`, etc.) are **permanently installed** in your project's agent folder (`.claude/`, `.github/prompts/`, `.pi/prompts/`, etc.). Your AI assistant reads these command files directly—no need to run `specify` again.
+
+**If your agent isn't recognizing slash commands:**
+
+1. **Verify command files exist:**
+
+   ```bash
+   # For GitHub Copilot
+   ls -la .github/prompts/
+
+   # For Claude
+   ls -la .claude/commands/
+
+   # For Pi
+   ls -la .pi/prompts/
+   ```
+
+2. **Restart your IDE/editor completely** (not just reload window)
+
+3. **Check you're in the correct directory** where you ran `specify init`
+
+4. **For some agents**, you may need to reload the workspace or clear cache
+
+**Related issue:** If Copilot can't open local files or uses PowerShell commands unexpectedly, this is typically an IDE context issue, not related to `specify`. Try:
+
+- Restarting VS Code
+- Checking file permissions
+- Ensuring the workspace folder is properly opened
+
+---
+
+## Version Compatibility
+
+Spec Kit follows semantic versioning for major releases. The CLI and project files are designed to be compatible within the same major version.
+
+**Best practice:** Keep both CLI and project files in sync by upgrading both together during major version changes.
+
+---
+
+## Next Steps
+
+After upgrading:
+
+- **Test new slash commands:** Run `/speckit.constitution` or another command to verify everything works
+- **Review release notes:** Check [GitHub Releases](https://github.com/github/spec-kit/releases) for new features and breaking changes
+- **Update workflows:** If new commands were added, update your team's development workflows
+- **Check documentation:** Visit [github.io/spec-kit](https://github.github.io/spec-kit/) for updated guides

+**File**: `.specify/extensions/{extension-id}/{extension-id}-config.yml`
+
+Extensions define their own config schema. Common patterns:
+
+```yaml
+# Connection settings
+connection:
+  url: string
+  api_key: string
+
+# Project settings
+project:
+  key: string
+  workspace: string
+
+# Feature flags
+features:
+  enabled: boolean
+  auto_sync: boolean
+
+# Defaults
+defaults:
+  labels: [string]
+  assignee: string
+
+# Custom fields
+field_mappings:
+  internal_name: "external_field_id"
+```
+
+### Config Layers
+
+1. **Extension Defaults** (from `extension.yml` `defaults` section)
+2. **Project Config** (`{extension-id}-config.yml`)
+3. **Local Override** (`{extension-id}-config.local.yml`, gitignored)
+4. **Environment Variables** (`SPECKIT_{EXTENSION}_*`)
+
+### Environment Variable Pattern
+
+Format: `SPECKIT_{EXTENSION}_{KEY}`
+
+Examples:
+
+- `SPECKIT_JIRA_PROJECT_KEY`
+- `SPECKIT_LINEAR_API_KEY`
+- `SPECKIT_GITHUB_TOKEN`
+
+---
+
+## Hook System
+
+### Hook Definition
+
+**In extension.yml**:
+
+```yaml
+hooks:
+  after_tasks:
+    command: "speckit.jira.specstoissues"
+    optional: true
+    prompt: "Create Jira issues from tasks?"
+    description: "Automatically create Jira hierarchy"
+    condition: null
+```
+

+      version: ">=1.0.0"
+  commands:                             # Optional: Core commands needed
+    - "speckit.tasks"
+
+provides:
+  commands:
+    - name: "speckit.my-ext.hello"      # Must follow pattern: speckit.{ext-id}.{cmd}
+      file: "commands/hello.md"
+      description: "Say hello"
+      aliases: ["speckit.my-ext.hi"]    # Optional aliases, same pattern
+
+  config:                               # Optional: Config files
+    - name: "my-ext-config.yml"

+tags:                                   # Optional: For catalog search
+  - "example"
+  - "utility"
+```
+
+### 3. Create Commands Directory
+
+```bash
+mkdir commands
+```
+
+### 4. Create Command File
+
+**File**: `commands/hello.md`
+
+```markdown
+---
+description: "Say hello command"
+tools:                              # Optional: AI tools this command uses
+  - 'some-tool/function'
+scripts:                            # Optional: Helper scripts
+  sh: ../../scripts/bash/helper.sh
+  ps: ../../scripts/powershell/helper.ps1
+---
+
+# Hello Command
+
+This command says hello!
+
+## User Input
+
+$ARGUMENTS
+
+## Steps
+
+1. Greet the user
+2. Show extension is working
+
+```bash
+echo "Hello from my extension!"
+echo "Arguments: $ARGUMENTS"
+```
+
+## Extension Configuration
+
+Load extension config from `.specify/extensions/my-ext/my-ext-config.yml`.
+
+### 5. Test Locally
+
+```bash
+cd /path/to/spec-kit-project
+specify extension add --dev /path/to/my-extension
+```
+
+### 6. Verify Installation
+
+```bash
+specify extension list
+
+# Should show:
+#  ✓ My Extension (v1.0.0)
+#     My custom extension
+#     Commands: 1 | Hooks: 1 | Status: Enabled
+```
+
+### 7. Test Command
+
+If using Claude:
+
+```bash
+claude
+> /speckit.my-ext.hello world
+```
+
+The command will be available in `.claude/commands/speckit.my-ext.hello.md`.

+---
+
+## Command File Format
+
+### Frontmatter (YAML)
+
+```yaml
+---
+description: "Command description"          # Required
+tools:                                      # Optional
+  - 'tool-name/function'
+scripts:                                    # Optional
+  sh: ../../scripts/bash/helper.sh
+  ps: ../../scripts/powershell/helper.ps1
+---
+```
+
+### Body (Markdown)
+
+Use standard Markdown with special placeholders:
+
+- `$ARGUMENTS`: User-provided arguments
+- `{SCRIPT}`: Replaced with script path during registration
+
+**Example**:
+
+````markdown
+## Steps
+
+1. Parse arguments
+2. Execute logic
+
+```bash
+args="$ARGUMENTS"
+echo "Running with args: $args"
+```
+````
+
+### Script Path Rewriting
+
+Extension commands use relative paths that get rewritten during registration:
+
+**In extension**:
+
+```yaml
+scripts:
+  sh: ../../scripts/bash/helper.sh
+```
+
+**After registration**:
+
+```yaml
+scripts:
+  sh: .specify/scripts/bash/helper.sh
+```
+
+This allows scripts to reference core spec-kit scripts.
+
+---
+
+## Configuration Files
+
+### Config Template
+
+**File**: `my-ext-config.template.yml`
+
+```yaml
+# My Extension Configuration
+# Copy this to my-ext-config.yml and customize
+
+# Example configuration
+api:
+  endpoint: "https://api.example.com"
+  timeout: 30
+
+features:
+  feature_a: true
+  feature_b: false
+
+credentials:
+  # DO NOT commit credentials!
+  # Use environment variables instead
+  api_key: "${MY_EXT_API_KEY}"
+```
+
+### Config Loading
+
+In your command, load config with layered precedence:
+
+1. Extension defaults (`extension.yml` → `defaults`)
+2. Project config (`.specify/extensions/my-ext/my-ext-config.yml`)
+3. Local overrides (`.specify/extensions/my-ext/my-ext-config.local.yml` - gitignored)
+4. Environment variables (`SPECKIT_MY_EXT_*`)
+
+**Example loading script**:
+
+```bash
+#!/usr/bin/env bash
+EXT_DIR=".specify/extensions/my-ext"
+
+# Load and merge config
+config=$(yq eval '.' "$EXT_DIR/my-ext-config.yml" -o=json)
+
+# Apply env overrides
+if [ -n "${SPECKIT_MY_EXT_API_KEY:-}" ]; then
+  config=$(echo "$config" | jq ".api.api_key = \"$SPECKIT_MY_EXT_API_KEY\"")
+fi
+
+echo "$config"
+```
+
+---
+
+## Excluding Files with `.extensionignore`
+
+Extension authors can create a `.extensionignore` file in the extension root to exclude files and folders from being copied when a user installs the extension with `specify extension add`. This is useful for keeping development-only files (tests, CI configs, docs source, etc.) out of the installed copy.
+
+### Format
+
+The file uses `.gitignore`-compatible patterns (one per line), powered by the [`pathspec`](https://pypi.org/project/pathspec/) library:
+
+- Blank lines are ignored
+- Lines starting with `#` are comments
+- `*` matches anything **except** `/` (does not cross directory boundaries)
+- `**` matches zero or more directories (e.g., `docs/**/*.draft.md`)
+- `?` matches any single character except `/`
+- A trailing `/` restricts a pattern to directories only
+- Patterns containing `/` (other than a trailing slash) are anchored to the extension root
+- Patterns without `/` match at any depth in the tree
+- `!` negates a previously excluded pattern (re-includes a file)
+- Backslashes in patterns are normalised to forward slashes for cross-platform compatibility
+- The `.extensionignore` file itself is always excluded automatically
+
+### Example
+
+```gitignore
+# .extensionignore
+
+# Development files
+tests/
+.github/
+.gitignore
+
+# Build artifacts
+__pycache__/
+*.pyc
+dist/
+
+# Documentation source (keep only the built README)
+docs/
+CONTRIBUTING.md
+```
+
+### Pattern Matching
+
+| Pattern | Matches | Does NOT match |
+|---------|---------|----------------|
+| `*.pyc` | Any `.pyc` file in any directory | — |
+| `tests/` | The `tests` directory (and all its contents) | A file named `tests` |
+| `docs/*.draft.md` | `docs/api.draft.md` (directly inside `docs/`) | `docs/sub/api.draft.md` (nested) |
+| `.env` | The `.env` file at any level | — |
+| `!README.md` | Re-includes `README.md` even if matched by an earlier pattern | — |
+| `docs/**/*.draft.md` | `docs/api.draft.md`, `docs/sub/api.draft.md` | — |
+
+### Unsupported Features
+
+The following `.gitignore` features are **not applicable** in this context:
+
+- **Multiple `.extensionignore` files**: Only a single file at the extension root is supported (`.gitignore` supports files in subdirectories)
+- **`$GIT_DIR/info/exclude` and `core.excludesFile`**: These are Git-specific and have no equivalent here
+- **Negation inside excluded directories**: Because file copying uses `shutil.copytree`, excluding a directory prevents recursion into it entirely. A negation pattern cannot re-include a file inside a directory that was itself excluded. For example, the combination `tests/` followed by `!tests/important.py` will **not** preserve `tests/important.py` — the `tests/` directory is skipped at the root level and its contents are never evaluated. To work around this, exclude the directory's contents individually instead of the directory itself (e.g., `tests/*.pyc` and `tests/.cache/` rather than `tests/`).
+
+---
+
+## Validation Rules
+
+### Extension ID
+
+- **Pattern**: `^[a-z0-9-]+$`
+- **Valid**: `my-ext`, `tool-123`, `awesome-plugin`
+- **Invalid**: `MyExt` (uppercase), `my_ext` (underscore), `my ext` (space)
+
+### Extension Version
+
+- **Format**: Semantic versioning (MAJOR.MINOR.PATCH)
+- **Valid**: `1.0.0`, `0.1.0`, `2.5.3`
+- **Invalid**: `1.0`, `v1.0.0`, `1.0.0-beta`
+
+### Command Name
+
+- **Pattern**: `^speckit\.[a-z0-9-]+\.[a-z0-9-]+$`
+- **Valid**: `speckit.my-ext.hello`, `speckit.tool.cmd`
+- **Invalid**: `my-ext.hello` (missing prefix), `speckit.hello` (no extension namespace)
+
+### Command File Path
+
+- **Must be** relative to extension root
+- **Valid**: `commands/hello.md`, `commands/subdir/cmd.md`
+- **Invalid**: `/absolute/path.md`, `../outside.md`
+

+import pytest
+from pathlib import Path
+from specify_cli.extensions import ExtensionManifest
+
+def test_manifest_valid():
+    """Test extension manifest is valid."""
+    manifest = ExtensionManifest(Path("extension.yml"))
+    assert manifest.id == "my-ext"
+    assert len(manifest.commands) >= 1
+
+def test_command_files_exist():
+    """Test all command files exist."""
+    manifest = ExtensionManifest(Path("extension.yml"))
+    for cmd in manifest.commands:

+specify extension add <extension-name> --from https://github.com/.../spec-kit-my-ext-1.0.0.zip
+```
+
+### Option 3: Community Reference Catalog
+
+Submit to the community catalog for public discovery:
+
+1. **Fork** spec-kit repository
+2. **Add entry** to `extensions/catalog.community.json`
+3. **Update** the Community Extensions table in `README.md` with your extension
+4. **Create PR** following the [Extension Publishing Guide](EXTENSION-PUBLISHING-GUIDE.md)
+5. **After merge**, your extension becomes available:
+   - Users can browse `catalog.community.json` to discover your extension
+   - Users copy the entry to their own `catalog.json`
+   - Users install with: `specify extension add my-ext` (from their catalog)
+
+See the [Extension Publishing Guide](EXTENSION-PUBLISHING-GUIDE.md) for detailed submission instructions.

+
+## Best Practices
+
+### Naming Conventions
+
+- **Extension ID**: Use descriptive, hyphenated names (`jira-integration`, not `ji`)
+- **Commands**: Use verb-noun pattern (`create-issue`, `sync-status`)
+- **Config files**: Match extension ID (`jira-config.yml`)
+
+### Documentation
+
+- **README.md**: Overview, installation, usage
+- **CHANGELOG.md**: Version history
+- **docs/**: Detailed guides
+- **Command descriptions**: Clear, concise
+
+### Versioning
+
+- **Follow SemVer**: `MAJOR.MINOR.PATCH`
+- **MAJOR**: Breaking changes
+- **MINOR**: New features
+- **PATCH**: Bug fixes
+
+### Security
+
+- **Never commit secrets**: Use environment variables
+- **Validate input**: Sanitize user arguments
+- **Document permissions**: What files/APIs are accessed
+
+### Compatibility
+
+- **Specify version range**: Don't require exact version
+- **Test with multiple versions**: Ensure compatibility
+- **Graceful degradation**: Handle missing features
+
+---
+
+## Example Extensions
+
+### Minimal Extension
+
+Smallest possible extension:
+
+```yaml
+# extension.yml
+schema_version: "1.0"
+extension:
+  id: "minimal"
+  name: "Minimal Extension"
+  version: "1.0.0"
+  description: "Minimal example"
+requires:
+  speckit_version: ">=0.1.0"
+provides:
+  commands:
+    - name: "speckit.minimal.hello"
+      file: "commands/hello.md"
+```
+
+````markdown
+<!-- commands/hello.md -->
+---
+description: "Hello command"
+---
+
+# Hello World
+
+```bash
+echo "Hello, $ARGUMENTS!"
+```
+````
+
+### Extension with Config
+
+Extension using configuration:
+
+```yaml
+# extension.yml
+# ... metadata ...
+provides:
+  config:
+    - name: "tool-config.yml"
+      template: "tool-config.template.yml"
+      required: true
+```
+
+```yaml
+# tool-config.template.yml
+api_endpoint: "https://api.example.com"
+timeout: 30
+```
+
+````markdown
+<!-- commands/use-config.md -->
+# Use Config
+
+Load config:
+```bash
+config_file=".specify/extensions/tool/tool-config.yml"
+endpoint=$(yq eval '.api_endpoint' "$config_file")
+echo "Using endpoint: $endpoint"
+```
+````
+
+### Extension with Hooks
+
+Extension that runs automatically:
+
+```yaml
+# extension.yml
+hooks:
+  after_tasks:
+    command: "speckit.auto.analyze"
+    optional: false  # Always run
+    description: "Analyze tasks after generation"
+```
+
+---
+
+## Troubleshooting
+
+### Extension won't install
+
+**Error**: `Invalid extension ID`
+
+- **Fix**: Use lowercase, alphanumeric + hyphens only
+
+**Error**: `Extension requires spec-kit >=0.2.0`
+
+- **Fix**: Update spec-kit with `uv tool install specify-cli --force`
+
+**Error**: `Command file not found`
+
+- **Fix**: Ensure command files exist at paths specified in manifest
+
+### Commands not registered
+
+**Symptom**: Commands don't appear in AI agent
+
+**Check**:
+
+1. `.claude/commands/` directory exists
+2. Extension installed successfully
+3. Commands registered in registry:
+
+   ```bash
+   cat .specify/extensions/.registry
+   ```
+
+**Fix**: Reinstall extension to trigger registration
+
+### Config not loading
+
+**Check**:
+
+1. Config file exists: `.specify/extensions/{ext-id}/{ext-id}-config.yml`
+2. YAML syntax is valid: `yq eval '.' config.yml`
+3. Environment variables set correctly
+
+---
+

+3. [Submit to Catalog](#submit-to-catalog)
+4. [Verification Process](#verification-process)
+5. [Release Workflow](#release-workflow)
+6. [Best Practices](#best-practices)
+
+---
+
+## Prerequisites
+
+Before publishing an extension, ensure you have:
+
+1. **Valid Extension**: A working extension with a valid `extension.yml` manifest
+2. **Git Repository**: Extension hosted on GitHub (or other public git hosting)
+3. **Documentation**: README.md with installation and usage instructions
+4. **License**: Open source license file (MIT, Apache 2.0, etc.)
+5. **Versioning**: Semantic versioning (e.g., 1.0.0)
+6. **Testing**: Extension tested on real projects
+
+---
+
+## Prepare Your Extension
+
+### 1. Extension Structure
+
+Ensure your extension follows the standard structure:
+
+```text
+your-extension/
+├── extension.yml              # Required: Extension manifest
+├── README.md                  # Required: Documentation
+├── LICENSE                    # Required: License file
+├── CHANGELOG.md               # Recommended: Version history
+├── .gitignore                 # Recommended: Git ignore rules
+│
+├── commands/                  # Extension commands
+│   ├── command1.md
+│   └── command2.md
+│
+├── config-template.yml        # Config template (if needed)
+│
+└── docs/                      # Additional documentation
+    ├── usage.md
+    └── examples/
+```
+
+### 2. extension.yml Validation
+
+Verify your manifest is valid:
+
+```yaml
+schema_version: "1.0"
+
+extension:
+  id: "your-extension"           # Unique lowercase-hyphenated ID
+  name: "Your Extension Name"     # Human-readable name
+  version: "1.0.0"                # Semantic version
+  description: "Brief description (one sentence)"
+  author: "Your Name or Organization"
+  repository: "https://github.com/your-org/spec-kit-your-extension"
+  license: "MIT"
+  homepage: "https://github.com/your-org/spec-kit-your-extension"
+
+requires:
+  speckit_version: ">=0.1.0"    # Required spec-kit version
+
+provides:
+  commands:                       # List all commands
+    - name: "speckit.your-extension.command"
+      file: "commands/command.md"
+      description: "Command description"
+
+tags:                             # 2-5 relevant tags
+  - "category"
+  - "tool-name"
+```
+
+**Validation Checklist**:
+
+- ✅ `id` is lowercase with hyphens only (no underscores, spaces, or special characters)
+- ✅ `version` follows semantic versioning (X.Y.Z)
+- ✅ `description` is concise (under 100 characters)
+- ✅ `repository` URL is valid and public
+- ✅ All command files exist in the extension directory
+- ✅ Tags are lowercase and descriptive
+
+### 3. Create GitHub Release
+
+Create a GitHub release for your extension version:
+
+```bash
+# Tag the release
+git tag v1.0.0
+git push origin v1.0.0
+
+# Create release on GitHub
+# Go to: https://github.com/your-org/spec-kit-your-extension/releases/new
+# - Tag: v1.0.0
+# - Title: v1.0.0 - Release Name
+# - Description: Changelog/release notes
+```
+
+The release archive URL will be:
+
+```text
+https://github.com/your-org/spec-kit-your-extension/archive/refs/tags/v1.0.0.zip
+```
+
+### 4. Test Installation
+
+Test that users can install from your release:
+
+```bash
+# Test dev installation
+specify extension add --dev /path/to/your-extension
+
+# Test from GitHub archive
+specify extension add <extension-name> --from https://github.com/your-org/spec-kit-your-extension/archive/refs/tags/v1.0.0.zip
+```
+
+---
+
+## Submit to Catalog
+
+### Understanding the Catalogs
+
+Spec Kit uses a dual-catalog system. For details about how catalogs work, see the main [Extensions README](README.md#extension-catalogs).
+
+**For extension publishing**: All community extensions should be added to `catalog.community.json`. Users browse this catalog and copy extensions they trust into their own `catalog.json`.
+
+### 1. Fork the spec-kit Repository
+
+```bash
+# Fork on GitHub
+# https://github.com/github/spec-kit/fork
+
+# Clone your fork
+git clone https://github.com/YOUR-USERNAME/spec-kit.git
+cd spec-kit
+```
+
+### 2. Add Extension to Community Catalog
+
+Edit `extensions/catalog.community.json` and add your extension:
+
+```json
+{
+  "schema_version": "1.0",
+  "updated_at": "2026-01-28T15:54:00Z",
+  "catalog_url": "https://raw.githubusercontent.com/github/spec-kit/main/extensions/catalog.community.json",
+  "extensions": {
+    "your-extension": {
+      "name": "Your Extension Name",
+      "id": "your-extension",
+      "description": "Brief description of your extension",
+      "author": "Your Name",
+      "version": "1.0.0",
+      "download_url": "https://github.com/your-org/spec-kit-your-extension/archive/refs/tags/v1.0.0.zip",
+      "repository": "https://github.com/your-org/spec-kit-your-extension",
+      "homepage": "https://github.com/your-org/spec-kit-your-extension",
+      "documentation": "https://github.com/your-org/spec-kit-your-extension/blob/main/docs/",
+      "changelog": "https://github.com/your-org/spec-kit-your-extension/blob/main/CHANGELOG.md",
+      "license": "MIT",
+      "requires": {
+        "speckit_version": ">=0.1.0",
+        "tools": [
+          {
+            "name": "required-mcp-tool",
+            "version": ">=1.0.0",
+            "required": true
+          }
+        ]
+      },
+      "provides": {
+        "commands": 3,
+        "hooks": 1
+      },
+      "tags": [
+        "category",
+        "tool-name",
+        "feature"
+      ],
+      "verified": false,
+      "downloads": 0,
+      "stars": 0,
+      "created_at": "2026-01-28T00:00:00Z",
+      "updated_at": "2026-01-28T00:00:00Z"
+    }
+  }
+}
+```
+
+**Important**:
+
+- Set `verified: false` (maintainers will verify)
+- Set `downloads: 0` and `stars: 0` (auto-updated later)
+- Use current timestamp for `created_at` and `updated_at`
+- Update the top-level `updated_at` to current time
+
+### 3. Update Community Extensions Table
+
+Add your extension to the Community Extensions table in the project root `README.md`:
+
+```markdown
+| Your Extension Name | Brief description of what it does | `<category>` | <effect> | [repo-name](https://github.com/your-org/spec-kit-your-extension) |
+```
+
+**(Table) Category** — pick the one that best fits your extension:
+
+- `docs` — reads, validates, or generates spec artifacts
+- `code` — reviews, validates, or modifies source code
+- `process` — orchestrates workflow across phases
+- `integration` — syncs with external platforms
+- `visibility` — reports on project health or progress
+
+**Effect** — choose one:
+
+- Read-only — produces reports without modifying files
+- Read+Write — modifies files, creates artifacts, or updates specs
+
+Insert your extension in alphabetical order in the table.
+
+### 4. Submit Pull Request
+
+```bash
+# Create a branch
+git checkout -b add-your-extension
+
+# Commit your changes
+git add extensions/catalog.community.json README.md
+git commit -m "Add your-extension to community catalog

+
+## Release Workflow
+
+### Publishing New Versions
+
+When releasing a new version:
+
+1. **Update version** in `extension.yml`:
+
+   ```yaml
+   extension:
+     version: "1.1.0"  # Updated version
+   ```
+
+2. **Update CHANGELOG.md**:
+
+   ```markdown
+   ## [1.1.0] - 2026-02-15
+
+   ### Added
+   - New feature X
+
+   ### Fixed
+   - Bug fix Y
+   ```
+
+3. **Create GitHub release**:
+
+   ```bash
+   git tag v1.1.0
+   git push origin v1.1.0
+   # Create release on GitHub
+   ```
+
+4. **Update catalog**:
+
+   ```bash
+   # Fork spec-kit repo (or update existing fork)
+   cd spec-kit
+
+   # Update extensions/catalog.json
+   jq '.extensions["your-extension"].version = "1.1.0"' extensions/catalog.json > tmp.json && mv tmp.json extensions/catalog.json
+   jq '.extensions["your-extension"].download_url = "https://github.com/your-org/spec-kit-your-extension/archive/refs/tags/v1.1.0.zip"' extensions/catalog.json > tmp.json && mv tmp.json extensions/catalog.json
+   jq '.extensions["your-extension"].updated_at = "2026-02-15T00:00:00Z"' extensions/catalog.json > tmp.json && mv tmp.json extensions/catalog.json
+   jq '.updated_at = "2026-02-15T00:00:00Z"' extensions/catalog.json > tmp.json && mv tmp.json extensions/catalog.json
+
+   # Submit PR
+   git checkout -b update-your-extension-v1.1.0
+   git add extensions/catalog.json
+   git commit -m "Update your-extension to v1.1.0"
+   git push origin update-your-extension-v1.1.0
+   ```
+
+5. **Submit update PR** with changelog in description
+
+---
+
+## Best Practices
+
+### Extension Design
+
+1. **Single Responsibility**: Each extension should focus on one tool/integration
+2. **Clear Naming**: Use descriptive, unambiguous names
+3. **Minimal Dependencies**: Avoid unnecessary dependencies
+4. **Backward Compatibility**: Follow semantic versioning strictly
+
+### Documentation
+
+1. **README.md Structure**:
+   - Overview and features
+   - Installation instructions
+   - Configuration guide
+   - Usage examples
+   - Troubleshooting
+   - Contributing guidelines
+
+2. **Command Documentation**:
+   - Clear description
+   - Prerequisites listed
+   - Step-by-step instructions
+   - Error handling guidance
+   - Examples
+
+3. **Configuration**:
+   - Provide template file
+   - Document all options
+   - Include examples
+   - Explain defaults
+
+### Security
+
+1. **Input Validation**: Validate all user inputs
+2. **No Hardcoded Secrets**: Never include credentials
+3. **Safe Dependencies**: Only use trusted dependencies
+4. **Audit Regularly**: Check for vulnerabilities
+
+### Maintenance
+
+1. **Respond to Issues**: Address issues within 1-2 weeks
+2. **Regular Updates**: Keep dependencies updated
+3. **Changelog**: Maintain detailed changelog
+4. **Deprecation**: Give advance notice for breaking changes
+
+### Community
+
+1. **License**: Use permissive open-source license (MIT, Apache 2.0)
+2. **Contributing**: Welcome contributions
+3. **Code of Conduct**: Be respectful and inclusive
+4. **Support**: Provide ways to get help (issues, discussions, email)
+
+---
+
+## FAQ
+
+### Q: Can I publish private/proprietary extensions?
+
+A: The main catalog is for public extensions only. For private extensions:
+
+- Host your own catalog.json file
+- Users add your catalog: `specify extension add-catalog https://your-domain.com/catalog.json`
+- Not yet implemented - coming in Phase 4
+
+### Q: How long does verification take?
+
+A: Typically 3-7 business days for initial review. Updates to verified extensions are usually faster.
+
+### Q: What if my extension is rejected?
+
+A: You'll receive feedback on what needs to be fixed. Make the changes and resubmit.
+
+### Q: Can I update my extension anytime?
+
+A: Yes, submit a PR to update the catalog with your new version. Verified status may be re-evaluated for major changes.
+
+### Q: Do I need to be verified to be in the catalog?
+
+A: No, unverified extensions are still searchable. Verification just adds trust and visibility.
+
+### Q: Can extensions have paid features?
+
+A: Extensions should be free and open-source. Commercial support/services are allowed, but core functionality must be free.

+# Spec Kit Extensions
+
+Extension system for [Spec Kit](https://github.com/github/spec-kit) - add new functionality without bloating the core framework.
+
+## Extension Catalogs
+
+Spec Kit provides two catalog files with different purposes:
+
+### Your Catalog (`catalog.json`)
+
+- **Purpose**: Default upstream catalog of extensions used by the Spec Kit CLI
+- **Default State**: Empty by design in the upstream project - you or your organization populate a fork/copy with extensions you trust
+- **Location (upstream)**: `extensions/catalog.json` in the GitHub-hosted spec-kit repo
+- **CLI Default**: The `specify extension` commands use the upstream catalog URL by default, unless overridden
+- **Org Catalog**: Point `SPECKIT_CATALOG_URL` at your organization's fork or hosted catalog JSON to use it instead of the upstream default
+- **Customization**: Copy entries from the community catalog into your org catalog, or add your own extensions directly
+
+**Example override:**
+```bash
+# Override the default upstream catalog with your organization's catalog
+export SPECKIT_CATALOG_URL="https://your-org.com/spec-kit/catalog.json"
+specify extension search  # Now uses your organization's catalog instead of the upstream default
+```
+
+### Community Reference Catalog (`catalog.community.json`)
+
+> [!NOTE]
+> Community extensions are independently created and maintained by their respective authors. GitHub and the Spec Kit maintainers may review pull requests that add entries to the community catalog for formatting, catalog structure, or policy compliance, but they do **not review, audit, endorse, or support the extension code itself**. Review extension source code before installation and use at your own discretion.
+
+- **Purpose**: Browse available community-contributed extensions
+- **Status**: Active - contains extensions submitted by the community
+- **Location**: `extensions/catalog.community.json`
+- **Usage**: Reference catalog for discovering available extensions
+- **Submission**: Open to community contributions via Pull Request
+
+**How It Works:**
+
+## Making Extensions Available
+
+You control which extensions your team can discover and install:
+
+### Option 1: Curated Catalog (Recommended for Organizations)
+
+Populate your `catalog.json` with approved extensions:
+
+1. **Discover** extensions from various sources:
+   - Browse `catalog.community.json` for community extensions
+   - Find private/internal extensions in your organization's repos
+   - Discover extensions from trusted third parties
+2. **Review** extensions and choose which ones you want to make available
+3. **Add** those extension entries to your own `catalog.json`
+4. **Team members** can now discover and install them:
+   - `specify extension search` shows your curated catalog
+   - `specify extension add <name>` installs from your catalog
+
+**Benefits**: Full control over available extensions, team consistency, organizational approval workflow
+
+**Example**: Copy an entry from `catalog.community.json` to your `catalog.json`, then your team can discover and install it by name.
+
+### Option 2: Direct URLs (For Ad-hoc Use)
+
+Skip catalog curation - team members install directly using URLs:
+
+```bash
+specify extension add <extension-name> --from https://github.com/org/spec-kit-ext/archive/refs/tags/v1.0.0.zip
+```
+
+**Benefits**: Quick for one-off testing or private extensions
+
+**Tradeoff**: Extensions installed this way won't appear in `specify extension search` for other team members unless you also add them to your `catalog.json`.
+
+## Available Community Extensions
+
+> [!NOTE]
+> Community extensions are independently created and maintained by their respective authors. GitHub and the Spec Kit maintainers may review pull requests that add entries to the community catalog for formatting, catalog structure, or policy compliance, but they do **not review, audit, endorse, or support the extension code itself**. The Community Extensions website is also a third-party resource. Review extension source code before installation and use at your own discretion.
+
+🔍 **Browse and search community extensions on the [Community Extensions website](https://speckit-community.github.io/extensions/).**
+
+See the [Community Extensions](../README.md#-community-extensions) section in the main README for the full list of available community-contributed extensions.
+
+For the raw catalog data, see [`catalog.community.json`](catalog.community.json).
+
+
+## Adding Your Extension
+
+### Submission Process
+
+To add your extension to the community catalog:
+
+1. **Prepare your extension** following the [Extension Development Guide](EXTENSION-DEVELOPMENT-GUIDE.md)

+# Git Branching Workflow Extension
+
+Git repository initialization, feature branch creation, numbering (sequential/timestamp), validation, remote detection, and auto-commit for Spec Kit.
+
+## Overview
+
+This extension provides Git operations as an optional, self-contained module. It manages:
+
+- **Repository initialization** with configurable commit messages
+- **Feature branch creation** with sequential (`001-feature-name`) or timestamp (`20260319-143022-feature-name`) numbering
+- **Branch validation** to ensure branches follow naming conventions
+- **Git remote detection** for GitHub integration (e.g., issue creation)
+- **Auto-commit** after core commands (configurable per-command with custom messages)
+

+
+## Configuration
+
+Configuration is stored in `.specify/extensions/git/git-config.yml`:
+
+```yaml
+# Branch numbering strategy: "sequential" or "timestamp"
+branch_numbering: sequential
+
+# Custom commit message for git init
+init_commit_message: "[Spec Kit] Initial commit"
+
+# Auto-commit per command (all disabled by default)
+# Example: enable auto-commit after specify
+auto_commit:
+  default: false
+  after_specify:
+    enabled: true
+    message: "[Spec Kit] Add specification"
+```
+
+## Installation
+
+```bash
+# Install the bundled git extension (no network required)
+specify extension add git
+```
+
+## Disabling
+
+```bash
+# Disable the git extension (spec creation continues without branching)
+specify extension disable git
+
+# Re-enable it
+specify extension enable git
+```
+
+## Graceful Degradation
+
+When Git is not installed or the directory is not a Git repository:
+- Spec directories are still created under `specs/`
+- Branch creation is skipped with a warning
+- Branch validation is skipped with a warning
+- Remote detection returns empty results
+
+## Scripts
+
+The extension bundles cross-platform scripts:
+
+- `scripts/bash/create-new-feature.sh` — Bash implementation
+- `scripts/bash/git-common.sh` — Shared Git utilities (Bash)
+- `scripts/powershell/create-new-feature.ps1` — PowerShell implementation
+- `scripts/powershell/git-common.ps1` — Shared Git utilities (PowerShell)

+
+# Auto-Commit Changes
+
+Automatically stage and commit all changes after a Spec Kit command completes.
+
+## Behavior
+
+This command is invoked as a hook after (or before) core commands. It:
+
+1. Determines the event name from the hook context (e.g., if invoked as an `after_specify` hook, the event is `after_specify`; if `before_plan`, the event is `before_plan`)
+2. Checks `.specify/extensions/git/git-config.yml` for the `auto_commit` section
+3. Looks up the specific event key to see if auto-commit is enabled
+4. Falls back to `auto_commit.default` if no event-specific key exists
+5. Uses the per-command `message` if configured, otherwise a default message
+6. If enabled and there are uncommitted changes, runs `git add .` + `git commit`
+
+## Execution
+
+Determine the event name from the hook that triggered this command, then run the script:
+
+- **Bash**: `.specify/extensions/git/scripts/bash/auto-commit.sh <event_name>`
+- **PowerShell**: `.specify/extensions/git/scripts/powershell/auto-commit.ps1 <event_name>`
+
+Replace `<event_name>` with the actual hook event (e.g., `after_specify`, `before_plan`, `after_implement`).
+
+## Configuration
+
+In `.specify/extensions/git/git-config.yml`:
+
+```yaml
+auto_commit:
+  default: false          # Global toggle — set true to enable for all commands
+  after_specify:
+    enabled: true          # Override per-command
+    message: "[Spec Kit] Add specification"
+  after_plan:
+    enabled: false
+    message: "[Spec Kit] Add implementation plan"
+```
+
+## Graceful Degradation
+
+- If Git is not available or the current directory is not a repository: skips with a warning
+- If no config file exists: skips (disabled by default)
+- If no changes to commit: skips with a message

+
+# Create Feature Branch
+
+Create and switch to a new git feature branch for the given specification. This command handles **branch creation only** — the spec directory and files are created by the core `/speckit.specify` workflow.
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Environment Variable Override
+
+If the user explicitly provided `GIT_BRANCH_NAME` (e.g., via environment variable, argument, or in their request), pass it through to the script by setting the `GIT_BRANCH_NAME` environment variable before invoking the script. When `GIT_BRANCH_NAME` is set:
+- The script uses the exact value as the branch name, bypassing all prefix/suffix generation
+- `--short-name`, `--number`, and `--timestamp` flags are ignored
+- `FEATURE_NUM` is extracted from the name if it starts with a numeric prefix, otherwise set to the full branch name
+
+## Prerequisites
+
+- Verify Git is available by running `git rev-parse --is-inside-work-tree 2>/dev/null`
+- If Git is not available, warn the user and skip branch creation
+
+## Branch Numbering Mode
+
+Determine the branch numbering strategy by checking configuration in this order:
+
+1. Check `.specify/extensions/git/git-config.yml` for `branch_numbering` value
+2. Check `.specify/init-options.json` for `branch_numbering` value (backward compatibility)
+3. Default to `sequential` if neither exists
+
+## Execution
+
+Generate a concise short name (2-4 words) for the branch:
+- Analyze the feature description and extract the most meaningful keywords
+- Use action-noun format when possible (e.g., "add-user-auth", "fix-payment-bug")
+- Preserve technical terms and acronyms (OAuth2, API, JWT, etc.)
+
+Run the appropriate script based on your platform:
+
+- **Bash**: `.specify/extensions/git/scripts/bash/create-new-feature.sh --json --short-name "<short-name>" "<feature description>"`
+- **Bash (timestamp)**: `.specify/extensions/git/scripts/bash/create-new-feature.sh --json --timestamp --short-name "<short-name>" "<feature description>"`
+- **PowerShell**: `.specify/extensions/git/scripts/powershell/create-new-feature.ps1 -Json -ShortName "<short-name>" "<feature description>"`
+- **PowerShell (timestamp)**: `.specify/extensions/git/scripts/powershell/create-new-feature.ps1 -Json -Timestamp -ShortName "<short-name>" "<feature description>"`
+
+**IMPORTANT**:
+- Do NOT pass `--number` — the script determines the correct next number automatically
+- Always include the JSON flag (`--json` for Bash, `-Json` for PowerShell) so the output can be parsed reliably
+- You must only ever run this script once per feature
+- The JSON output will contain `BRANCH_NAME` and `FEATURE_NUM`
+
+## Graceful Degradation
+
+If Git is not installed or the current directory is not a Git repository:
+- Branch creation is skipped with a warning: `[specify] Warning: Git repository not detected; skipped branch creation`
+- The script still outputs `BRANCH_NAME` and `FEATURE_NUM` so the caller can reference them
+
+## Output
+
+The script outputs JSON with:
+- `BRANCH_NAME`: The branch name (e.g., `003-user-auth` or `20260319-143022-user-auth`)
+- `FEATURE_NUM`: The numeric or timestamp prefix used

+
+# Initialize Git Repository
+
+Initialize a Git repository in the current project directory if one does not already exist.
+
+## Execution
+
+Run the appropriate script from the project root:
+
+- **Bash**: `.specify/extensions/git/scripts/bash/initialize-repo.sh`
+- **PowerShell**: `.specify/extensions/git/scripts/powershell/initialize-repo.ps1`
+
+If the extension scripts are not found, fall back to:
+- **Bash**: `git init && git add . && git commit -m "Initial commit from Specify template"`
+- **PowerShell**: `git init; git add .; git commit -m "Initial commit from Specify template"`
+
+The script handles all checks internally:
+- Skips if Git is not available
+- Skips if already inside a Git repository
+- Runs `git init`, `git add .`, and `git commit` with an initial commit message
+
+## Customization
+
+Replace the script to add project-specific Git initialization steps:
+- Custom `.gitignore` templates
+- Default branch naming (`git config init.defaultBranch`)
+- Git LFS setup
+- Git hooks installation
+- Commit signing configuration
+- Git Flow initialization
+
+## Output
+
+On success:
+- `✓ Git repository initialized`
+
+## Graceful Degradation
+
+If Git is not installed:
+- Warn the user
+- Skip repository initialization
+- The project continues to function without Git (specs can still be created under `specs/`)
+
+If Git is installed but `git init`, `git add .`, or `git commit` fails:
+- Surface the error to the user
+- Stop this command rather than continuing with a partially initialized repository

+# Detect Git Remote URL
+
+Detect the Git remote URL for integration with GitHub services (e.g., issue creation).
+
+## Prerequisites
+
+- Check if Git is available by running `git rev-parse --is-inside-work-tree 2>/dev/null`
+- If Git is not available, output a warning and return empty:
+  ```
+  [specify] Warning: Git repository not detected; cannot determine remote URL
+  ```
+
+## Execution
+
+Run the following command to get the remote URL:
+
+```bash
+git config --get remote.origin.url
+```
+
+## Output
+
+Parse the remote URL and determine:
+
+1. **Repository owner**: Extract from the URL (e.g., `github` from `https://github.com/github/spec-kit.git`)
+2. **Repository name**: Extract from the URL (e.g., `spec-kit` from `https://github.com/github/spec-kit.git`)
+3. **Is GitHub**: Whether the remote points to a GitHub repository
+
+Supported URL formats:
+- HTTPS: `https://github.com/<owner>/<repo>.git`
+- SSH: `git@github.com:<owner>/<repo>.git`
+
+> [!CAUTION]
+> ONLY report a GitHub repository if the remote URL actually points to github.com.
+> Do NOT assume the remote is GitHub if the URL format doesn't match.
+
+## Graceful Degradation
+
+If Git is not installed, the directory is not a Git repository, or no remote is configured:
+- Return an empty result
+- Do NOT error — other workflows should continue without Git remote information

+# Validate Feature Branch
+
+Validate that the current Git branch follows the expected feature branch naming conventions.
+
+## Prerequisites
+
+- Check if Git is available by running `git rev-parse --is-inside-work-tree 2>/dev/null`
+- If Git is not available, output a warning and skip validation:
+  ```
+  [specify] Warning: Git repository not detected; skipped branch validation
+  ```
+
+## Validation Rules
+
+Get the current branch name:
+
+```bash
+git rev-parse --abbrev-ref HEAD
+```
+
+The branch name must match one of these patterns:
+
+1. **Sequential**: `^[0-9]{3,}-` (e.g., `001-feature-name`, `042-fix-bug`, `1000-big-feature`)
+2. **Timestamp**: `^[0-9]{8}-[0-9]{6}-` (e.g., `20260319-143022-feature-name`)
+
+## Execution
+
+If on a feature branch (matches either pattern):
+- Output: `✓ On feature branch: <branch-name>`
+- Check if the corresponding spec directory exists under `specs/`:
+  - For sequential branches, look for `specs/<prefix>-*` where prefix matches the numeric portion
+  - For timestamp branches, look for `specs/<prefix>-*` where prefix matches the `YYYYMMDD-HHMMSS` portion
+- If spec directory exists: `✓ Spec directory found: <path>`
+- If spec directory missing: `⚠ No spec directory found for prefix <prefix>`
+
+If NOT on a feature branch:
+- Output: `✗ Not on a feature branch. Current branch: <branch-name>`
+- Output: `Feature branches should be named like: 001-feature-name or 20260319-143022-feature-name`
+
+## Graceful Degradation
+
+If Git is not installed or the directory is not a Git repository:
+- Check the `SPECIFY_FEATURE` environment variable as a fallback
+- If set, validate that value against the naming patterns
+- If not set, skip validation with a warning

+
+# Extension Self-Test: `$ARGUMENTS`
+
+This command drives a self-test simulating the developer experience with the `$ARGUMENTS` extension.
+
+## Goal
+
+Validate the end-to-end lifecycle (discovery, installation, registration) for the extension: `$ARGUMENTS`.
+If `$ARGUMENTS` is empty, you must tell the user to provide an extension name, for example: `/speckit.selftest.extension linear`.
+
+## Steps
+
+### Step 1: Catalog Discovery Validation
+
+Check if the extension exists in the Spec Kit catalog.
+Execute this command and verify that it completes successfully and that the returned extension ID exactly matches `$ARGUMENTS`. If the command fails or the ID does not match `$ARGUMENTS`, fail the test.
+
+```bash
+specify extension info "$ARGUMENTS"
+```
+
+### Step 2: Simulate Installation
+
+First, try to add the extension to the current workspace configuration directly. If the catalog provides the extension as `install_allowed: false` (discovery-only), this step is *expected* to fail.
+
+```bash
+specify extension add "$ARGUMENTS"
+```
+
+Then, simulate adding the extension by installing it from its catalog download URL, which should bypass the restriction.
+Obtain the extension's `download_url` from the catalog metadata (for example, via a catalog info command or UI), then run:
+
+```bash
+specify extension add "$ARGUMENTS" --from "<download_url>"
+```
+
+### Step 3: Registration Verification
+
+Once the `add` command completes, verify the installation by checking the project configuration.
+Use terminal tools (like `cat`) to verify that the following file contains a record for `$ARGUMENTS`.
+
+```bash
+cat .specify/extensions/.registry/$ARGUMENTS.json
+```
+
+### Step 4: Verification Report
+
+Analyze the standard output of the three steps. 
+Generate a terminal-style test output format detailing the results of discovery, installation, and registration. Return this directly to the user.
+
+Example output format:
+```text
+============================= test session starts ==============================
+collected 3 items
+
+test_selftest_discovery.py::test_catalog_search [PASS/FAIL]
+  Details: [Provide execution result of specify extension search]

+

+
+This calls the MCP server tool to execute the operation.
+``
+
+### Step 3: Process Results
+
+<!-- CUSTOMIZE: Add more steps as needed -->
+
+Process the results and provide output:
+
+`` bash
+echo ""
+echo "✅ Command completed successfully!"

+echo ""
+``
+
+### Step 4: Save Output (Optional)
+
+Save results to a file if needed:
+
+``bash
+output_file=".specify/my-extension-output.json"
+
+cat > "$output_file" <<EOF
+{
+  "timestamp": "$(date -u +"%Y-%m-%dT%H:%M:%SZ")",
+  "setting": "$setting_value",
+  "results": []
+}
+EOF
+
+echo "💾 Output saved to $output_file"
+``
+
+## Configuration Reference
+
+<!-- CUSTOMIZE: Document configuration options -->
+
+This command uses the following configuration from `my-extension-config.yml`:
+
+- **settings.key**: Description of what this setting does
+  - Type: string
+  - Required: Yes
+  - Example: `"example-value"`
+
+- **settings.another_key**: Description of another setting
+  - Type: boolean
+  - Required: No
+  - Default: `false`
+  - Example: `true`
+
+## Environment Variables
+
+<!-- CUSTOMIZE: Document environment variable overrides -->
+
+Configuration can be overridden with environment variables:
+
+- `SPECKIT_MY_EXTENSION_KEY` - Overrides `settings.key`
+- `SPECKIT_MY_EXTENSION_ANOTHER_KEY` - Overrides `settings.another_key`
+
+Example:
+``bash
+export SPECKIT_MY_EXTENSION_KEY="override-value"
+``
+
+## Troubleshooting
+
+<!-- CUSTOMIZE: Add common issues and solutions -->
+
+### "Configuration not found"
+
+**Solution**: Install the extension and create configuration:
+``bash
+specify extension add my-extension
+cp .specify/extensions/my-extension/config-template.yml \
+   .specify/extensions/my-extension/my-extension-config.yml
+``
+
+### "MCP tool not available"
+
+**Solution**: Ensure MCP server is configured in your AI agent settings.
+
+### "Permission denied"
+
+**Solution**: Check credentials and permissions in the external service.
+
+## Notes

+
+## Spec Kit Project Updates
+
+Spec Kit released versions **v0.1.7** through **v0.1.13** during February. Version 0.1.7 (early February) updated documentation for the newly introduced **dual-catalog extension system**, which allows both core and community extension catalogs to coexist. Subsequent patches (0.1.8, 0.1.9, etc.) bumped dependencies such as GitHub Actions versions and resolved minor issues. **v0.1.10** fixed YAML front-matter handling in generated files. By late February, **v0.1.12** and **v0.1.13** shipped with additional fixes in preparation for the next version bump. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+The main architectural addition was the **modular extension system** with separate "core" and "community" extension catalogs for third-party add-ons. Multiple community-contributed extensions were merged during the month, including a **Jira extension** for issue tracker integration, an **Azure DevOps extension**, and utility extensions for code review, retrospective documentation, and CI/CD sync. The pending 0.2.0 release changelog lists over a dozen changes from February, including the extension additions and support for **multiple agent catalogs concurrently**. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+By end of February, **over 330 issues/feature requests had been closed on GitHub** (out of ~870 filed to date). External contributors submitted pull requests including the **Tabnine CLI support**, which was merged in late February. The repository reached ~71k stars and crossed 6,000 forks. [\[github.com\]](https://github.com/github/spec-kit/issues) [\[github.com\]](https://github.com/github/spec-kit/releases) [\[rywalker.com\]](https://rywalker.com/research/github-spec-kit)
+
+On the stability side, February's work focused on tightening core workflows and fixing edge-case bugs in the specification, planning, and task-generation commands. The team addressed file-handling issues (e.g., clarifying how output files are created/appended) and improved the reliability of the automated release pipeline. The project also added **Kiro CLI** to the supported agent list and updated integration scripts for Cursor and Code Interpreter, bringing the total number of supported AI coding assistants to over 20. [\[github.com\]](https://github.com/github/spec-kit/releases) [\[github.com\]](https://github.com/github/spec-kit)
+
+## Community & Content
+
+**Eduardo Luz** published a LinkedIn article on Feb 15 titled *"Specification Driven Development (SDD) and the GitHub Spec Kit: Elevating Software Engineering."* The article draws on his experience as a senior engineer to describe common causes of technical debt and inconsistent designs, and how SDD addresses them. It walks through Spec Kit's **four-layer approach** (Constitution, Design, Tasks, Implementation) and discusses treating specifications as a source of truth. The post generated discussion among software architects on LinkedIn about reducing misunderstandings and rework through spec-driven workflows. [\[linkedin.com\]](https://www.linkedin.com/pulse/specification-driven-development-sdd-github-spec-kit-elevating-luz-tojmc?tl=en)
+
+**Erick Matsen** (Fred Hutchinson Cancer Center) posted a detailed walkthrough on Feb 10 titled *"Spec-Driven Development with spec-kit."* He describes building a **bioinformatics pipeline** in a single day using Spec Kit's workflow (from `speckit.constitution` to `speckit.implement`). The post includes command outputs and notes on decisions made along the way, such as refining the spec to add domain-specific requirements. He writes: "I really recommend this approach. This feels like the way software development should be." [\[matsen.fredhutch.org\]](https://matsen.fredhutch.org/general/2026/02/10/spec-kit-walkthrough.html) [\[github.com\]](https://github.com/mnriem/spec-kit-dotnet-cli-demo)
+
+Several other tutorials and guides appeared during the month. An article on *IntuitionLabs* (updated Feb 21) provided a guide to Spec Kit covering the philosophy behind SDD and a walkthrough of the four-phase workflow with examples. A piece by Ry Walker (Feb 22) summarized key aspects of Spec Kit, noting its agent-agnostic design and 71k-star count. Microsoft's Developer Blog post from late 2025 (*"Diving Into Spec-Driven Development with GitHub Spec Kit"* by Den Delimarsky) continued to circulate among new users. [\[intuitionlabs.ai\]](https://intuitionlabs.ai/articles/spec-driven-development-spec-kit) [\[rywalker.com\]](https://rywalker.com/research/github-spec-kit)
+
+On **Feb 25**, the Cleveland C# .NET User Group hosted a session titled *"Spec Driven Development with GitHub Spec Kit."* The talk was delivered by Microsoft MVP **[Eric Boyd](https://ericboyd.com/)** (Cleveland-based .NET developer; not to be confused with the Microsoft AI Platform VP of the same name). Boyd covered how specs change an AI coding assistant's output, patterns for iterating and refining specs over multiple cycles, and moving from ad-hoc prompting to a repeatable spec-driven workflow. Other groups, including GDG Madison, also listed sessions on spec-driven development in late February and early March. [\[ericboyd.com\]](https://ericboyd.com/events/cleveland-csharp-user-group-february-25-2026-spec-driven-development-sdd-github-spec-kit)
+
+On GitHub, the **Spec Kit Discussions forum** saw activity around installation troubleshooting, handling multi-feature projects with Spec Kit's branching model, and feature suggestions. One thread discussed how Spec Kit treats each spec as a short-lived artifact tied to a feature branch, which led to discussion about future support for long-running "spec of record" use cases. [\[martinfowler.com\]](https://martinfowler.com/articles/exploring-gen-ai/sdd-3-tools.html)
+
+## SDD Ecosystem
+
+Other spec-driven development tools also saw activity in February.
+
+AWS **Kiro** released version 0.10 on Feb 18 with two new spec workflows: a **Design-First** mode (starting from architecture/pseudocode to derive requirements) and a **Bugfix** mode (structured root-cause analysis producing a `bugfix.md` spec file). Kiro also added hunk-level code review for AI-generated changes and pre/post task hooks for custom automation. AWS expanded Kiro to GovCloud regions on Feb 17 for government compliance use cases. [\[kiro.dev\]](https://kiro.dev/changelog/)
+
+**OpenSpec** (by Fission AI), a lightweight SDD framework, reached ~29.3k stars and nearly 2k forks. Its community published guides and comparisons during the month, including *"Spec-Driven Development Made Easy: A Practical Guide with OpenSpec."* OpenSpec emphasizes simplicity and flexibility, integrating with multiple AI coding assistants via YAML configs.
+
+**Tessl** remained in private beta. As described by Thoughtworks writer Birgitta Boeckeler, Tessl pursues a **spec-as-source** model where specifications are maintained long-term and directly generate code files one-to-one, with generated code labeled as "do not edit." This contrasts with Spec Kit's current approach of creating specs per feature/branch. [\[martinfowler.com\]](https://martinfowler.com/articles/exploring-gen-ai/sdd-3-tools.html)
+
+An **arXiv preprint** (January 2026) categorized SDD implementations into three levels: *spec-first*, *spec-anchored*, and *spec-as-source*. Spec Kit was identified as primarily spec-first with elements of spec-anchored. Tech media published reviews including a *Vibe Coding* "GitHub Spec Kit Review (2026)" and a blog post titled *"Putting Spec Kit Through Its Paces: Radical Idea or Reinvented Waterfall?"* which concluded that SDD with AI assistance is more iterative than traditional Waterfall. [\[intuitionlabs.ai\]](https://intuitionlabs.ai/articles/spec-driven-development-spec-kit) [\[martinfowler.com\]](https://martinfowler.com/articles/exploring-gen-ai/sdd-3-tools.html)
+
+## Roadmap
+
+**v0.2.0** was released on March 10, 2026, consolidating the month's work. It includes new extensions (Jira, Azure DevOps, review, sync), support for multiple extension catalogs and community plugins, and additional agent integrations (Tabnine CLI, Kiro CLI). [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+Areas under discussion or in progress for future development:
+
+- **Spec lifecycle management** -- supporting longer-lived specifications that can evolve across multiple iterations, rather than being tied to a single feature branch. Users have raised this in GitHub Discussions, and the concept of "spec-anchored" development is under consideration. [\[martinfowler.com\]](https://martinfowler.com/articles/exploring-gen-ai/sdd-3-tools.html)
+- **CI/CD integration** -- incorporating Spec Kit verification (e.g., `speckit.checklist` or `speckit.verify`) into pull request workflows and project management tools. February's Jira and Azure DevOps extensions are a step in this direction. [\[github.com\]](https://github.com/github/spec-kit/releases)
+- **Continued agent support** -- adding integrations as new AI coding assistants emerge. The project currently supports over 20 agents and has been adding new ones (Kiro CLI, Tabnine CLI) as they become available. [\[github.com\]](https://github.com/github/spec-kit)
+- **Community ecosystem** -- the open extension model allows external contributors to add functionality directly. February's Jira and Azure DevOps plugins were community-contributed. The Spec Kit README now links to community walkthrough demos for .NET, Spring Boot, and other stacks. [\[github.com\]](https://github.com/github/spec-kit)

+
+***
+
+## Spec Kit Project Updates
+
+### Releases Overview
+
+**v0.2.0** (March 10) opened the month with **simultaneous multi-catalog support**, enabling both core and community extension catalogs at the same time. It added **Tabnine CLI** and **Kimi Code CLI** agents, four community extensions (Understanding, Ralph, Review, Fleet Orchestrator), and `.extensionignore` support. Patch **v0.2.1** fixed broken quickstart links and added catalog CLI help. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+**v0.3.0** (mid-March) delivered the **pluggable preset system** with catalog, resolver, and skills propagation. Presets let teams override default templates with their own conventions, using priority-based stacking. The release also added a **/selftest.extension** for testing extensions, **Mistral Vibe CLI**, migrated **Qwen Code CLI** from TOML to Markdown, and hardened bash scripts against shell injection. New community extensions included DocGuard CDD, Archive & Reconcile, specify-status, and specify-doctor. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+**v0.3.1** added before/after hook events, JSONC deep-merge for `settings.json`, and the **Trae IDE** agent. **v0.3.2** added **Junie**, **iFlow CLI**, and **Pi Coding Agent**, plus a preset submission template and an Extension Comparison Guide. Community extensions continued arriving: verify-tasks, conduct, cognitive-squad, speckit-utils, spec-kit-iterate, and spec-kit-learn. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+**v0.4.0** (late March) introduced **auto-registration of extension skills** — installed extensions' commands are now automatically exposed as agent skills. It also delivered **air-gapped/offline deployment** by embedding core templates in the CLI wheel and added timestamp-based branch naming. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+Three patches closed the month. **v0.4.1** fixed a missing Assumptions section in the spec template and improved repo root detection. **v0.4.2** added AIDE, Extensify, and Presetify to the community catalog, moved the community extensions table into the main README, and recognized the **Spec Kit Assistant VS Code extension** as a Community Friend. **v0.4.3** unified skill naming conventions and restored **PowerShell 5.1 compatibility**. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+### Bug Fixes and Security Hardening
+
+The most significant fix was **shell injection hardening** of bash scripts, addressing potential vulnerabilities from unsanitized git branch names and environment variables. Other fixes included switching to **global branch numbering** for consistent sequencing, suppressing git checkout exceptions and fetch stdout leaks, properly encoding JSON control characters, and adding explicit PowerShell positional binding. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+### The Extension Ecosystem
+
+By late March, over **20 community extensions** had been built for Spec Kit. Thulasi Rajasekaran's LinkedIn article *"The Feature That Turns Spec Kit Into a Platform"* highlighted standouts: **Conduct** (orchestrates SDD phases via sub-agents to avoid context pollution), **Verify Tasks** (catches "phantom completions" — tasks marked done with no real code), **Understanding** (31 quality metrics against specs based on IEEE/ISO standards), and the **Jira and Azure DevOps integrations**. [\[linkedin.com\]](https://www.linkedin.com/pulse/feature-turns-spec-kit-platform-extensions-presets-rajasekaran-3ejgc)
+
+Rajasekaran argued the real significance of presets is what they enable: the same machinery that turned "User Stories" into pirate-speak "Crew Tales" could enforce compliance requirements, add mandatory threat-model sections, or require test tasks before implementation tasks. Organizations can curate available extensions by hosting custom catalog URLs. [\[linkedin.com\]](https://www.linkedin.com/pulse/feature-turns-spec-kit-platform-extensions-presets-rajasekaran-3ejgc)
+
+## Community & Content
+
+### Developer Walkthroughs and Blog Posts
+
+March produced a wave of independent content as developers explored SDD in practice.
+
+**Tiago Valverde** published *"Spec-Driven Development in Practice: A Walkthrough with Spec Kit"* on March 14. He documents building an Instagram-style photo mural feature using the full Spec Kit workflow, contrasting it with previous ad-hoc prompting: while directly prompting Claude worked for small changes, complex work led to scope creep, ambiguous requirements discovered too late, and no artifacts left behind. Valverde recommends being specific in the initial prompt, reviewing `spec.md` immediately, and highlights the clarify step as particularly valuable. A shorter companion piece, *"The Shift from Vibe Coding to Spec-Driven Development,"* appeared on March 8. [\[tiagovalverde.com\]](https://www.tiagovalverde.com/posts/spec-driven-development-in-practice-a-walkthrough-with-spec-kit)
+
+**Alfredo Perez** published *"Build Your Own SDD Workflow"* on March 21, taking a deliberately contrarian approach. He praises SDD in principle but argues the full seven-step workflow carries too much ceremony for smaller tasks. His solution is a lean **4-step custom workflow** — `specify → plan → tasks → implement` — dropping constitution, clarify, and review, wired into the **SpecKit Companion** VS Code extension. The article highlights an important tradeoff: full rigor vs. lightweight adoption. Perez also presented this workflow at an **Angular Community Meetup** on March 25. [\[alfredo-perez.dev\]](https://www.alfredo-perez.dev/blog/2026-03-21-build-your-own-sdd-workflow)
+
+**Sergey Golubev** of prodfeat.ai published *"20+ SDD Frameworks: A Catalog for AI Development"* on March 17. The catalog organizes **20+ frameworks in 6 categories**, highlighting **BMAD-METHOD** (~41k stars, simulates an agile team from AI roles), **QuintCode + FPF** (preserves decision rationale via a 5-phase ADI Cycle), and **cc-sdd** (~2.9k stars, enforced SDD workflow for 8 tools). Golubev presents a three-level maturity model: *Spec-First* (spec per task, discarded after), *Spec-Anchored* (living document), and *Spec-as-Source* (spec is the only artifact). His conclusion: "SDD is not a fad… AI agents generate good code when the task is well-defined. Without a spec — you're rolling the dice." [\[prodfeat.ai\]](https://www.prodfeat.ai/en/blog/2026-03-17-sdd-frameworks-catalog)
+
+### Community Tools and Documentation
+
+The **Spec Kit Assistant VS Code extension** was formally recognized as a Community Friend and added to the README. The README was reorganized: community extensions table moved into the main page for discoverability, a community presets section was added, and the publishing guide gained Category and Effect columns. New walkthroughs included Java brownfield, Go/React brownfield dashboard, and the Spring Boot pirate-speak preset demo. [\[github.com\]](https://github.com/github/spec-kit/releases)
+
+A notable community project appeared: **speckit-pipeline** by iandeherdt — a pipeline atop Spec Kit with a **design loop** (designer + critic agents iterating in a browser) and a **build loop** (developer + evaluator agents verifying against acceptance criteria). An open issue (#1966) requests a built-in pipeline command, suggesting this pattern may eventually reach core.
+
+A public **Microsoft Learn** training module, *"Implement Spec-Driven Development using the GitHub Spec Kit"* (3 hours, 13 units), provided an onboarding path for enterprise developers.
+
+## SDD Ecosystem & Industry Trends
+
+### The "Vibe Coding Is Dead" Narrative
+
+*ByteIota* published *"Spec-Driven Development Kills 'Vibe Coding'"* on March 20, reporting AWS pushing SDD as the new standard. Key claims: over 100,000 developers adopting SDD approaches in early tool previews, AWS demonstrating a two-week feature completed in two days using Kiro IDE, and WEF research indicating 65% of developers expect their role to shift toward spec-first workflows in 2026. [\[byteiota.com\]](https://byteiota.com/spec-driven-development-kills-vibe-coding-march-2026/)
+
+Critics got equal space. *Marmelab* called SDD "the exact mistakes Agile was designed to solve." An *Isoform* controlled test found SDD took 33 minutes for 689 lines vs. 8 minutes with iterative prompting, with no measured quality improvement. The emerging consensus favored hybrids — a Red Hat developer captured it: "Use the vibes to explore. Use specifications to build." Other independent articles appeared from Shimon Ifrah, Raul Proenza (Cox Automotive), CGI, and Vishal Mysore. ByteIota also raised an underappreciated concern: if specs replace coding, how do juniors build the judgment to write good specs or review AI-generated code? [\[byteiota.com\]](https://byteiota.com/spec-driven-development-kills-vibe-coding-march-2026/)
+
+### Competitive Landscape
+
+**Augment Code** published *"Intent vs GitHub Spec Kit (2026): Platform or Framework?"* on March 31. The core tradeoff: Spec Kit's strength is **portability** across 22+ agents; Intent offers **living specs** with automated drift detection. The comparison surfaced spec drift as a key architectural concern — Spec Kit's specs can become stale post-implementation, and while community extensions address this, native real-time drift detection is not yet in core. [\[augmentcode.com\]](https://www.augmentcode.com/tools/intent-vs-github)
+
+The broader landscape continued evolving. OpenSpec held ~29.3k stars, BMAD-METHOD grew to ~41k, and Tessl continued in private beta. While Spec Kit leads in GitHub popularity and agent breadth, alternatives differentiate on orchestration depth (Intent, BMAD), enforced discipline (cc-sdd), decision trails (QuintCode), and spec-as-source vision (Tessl). [\[prodfeat.ai\]](https://www.prodfeat.ai/en/blog/2026-03-17-sdd-frameworks-catalog)
+
+## Roadmap
+
+Areas under discussion or in progress for future development:
+
+- **Spec lifecycle management** -- supporting longer-lived specifications that evolve across multiple iterations. The Augment Code comparison and community commentary highlighted "spec drift" as a key concern. The Archive & Reconcile extension (#1844) is a community step; a core solution is expected to be a focus area. [\[augmentcode.com\]](https://www.augmentcode.com/tools/intent-vs-github) [\[github.com\]](https://github.com/github/spec-kit/releases)
+- **CI/CD integration** -- incorporating Spec Kit verification into pull request workflows and failing builds when specs are out of alignment. The Jira and Azure DevOps extensions (#1764, #1734) are a first step. [\[github.com\]](https://github.com/github/spec-kit/releases)
+- **End-to-end workflow automation** -- an open issue (#1966) proposes a built-in pipeline command. The community-built **speckit-pipeline** by iandeherdt already demonstrates multi-agent loops with browser verification. [\[github.com\]](https://github.com/iandeherdt/speckit-pipeline)
+- **Continued agent expansion** -- seven new agents were added in March alone. The agent-agnostic design means support for emerging tools can be added by anyone. [\[byteiota.com\]](https://byteiota.com/spec-driven-development-kills-vibe-coding-march-2026/)
+- **Experience simplification** -- the preset system, custom workflows, and growing walkthrough library lower the learning curve, but extension discoverability will need a more robust solution as the catalog grows. [\[github.com\]](https://github.com/github/spec-kit/releases)
+- **Toward a stable release** -- nine releases in one month reflects pre-1.0 momentum. Reaching 1.0 will require stabilizing the extension and preset APIs and ensuring backward compatibility across the agent and extension surface area. [\[github.com\]](https://github.com/github/spec-kit/blob/main/newsletters/2026-February.md)

+# Preset System Architecture
+
+This document describes the internal architecture of the preset system — how template resolution, command registration, and catalog management work under the hood.
+
+For usage instructions, see [README.md](README.md).
+
+## Template Resolution
+
+When Spec Kit needs a template (e.g. `spec-template`), the `PresetResolver` walks a priority stack and returns the first match:
+
+```mermaid
+flowchart TD
+    A["resolve_template('spec-template')"] --> B{Override exists?}
+    B -- Yes --> C[".specify/templates/overrides/spec-template.md"]
+    B -- No --> D{Preset provides it?}
+    D -- Yes --> E[".specify/presets/‹preset-id›/templates/spec-template.md"]
+    D -- No --> F{Extension provides it?}
+    F -- Yes --> G[".specify/extensions/‹ext-id›/templates/spec-template.md"]
+    F -- No --> H[".specify/templates/spec-template.md"]
+
+    E -- "multiple presets?" --> I["lowest priority number wins"]
+    I --> E
+
+    style C fill:#4caf50,color:#fff
+    style E fill:#2196f3,color:#fff
+    style G fill:#ff9800,color:#fff
+    style H fill:#9e9e9e,color:#fff
+```
+
+| Priority | Source | Path | Use case |
+|----------|--------|------|----------|
+| 1 (highest) | Override | `.specify/templates/overrides/` | One-off project-local tweaks |
+| 2 | Preset | `.specify/presets/<id>/templates/` | Shareable, stackable customizations |
+| 3 | Extension | `.specify/extensions/<id>/templates/` | Extension-provided templates |
+| 4 (lowest) | Core | `.specify/templates/` | Shipped defaults |
+
+When multiple presets are installed, they're sorted by their `priority` field (lower number = higher precedence). This is set via `--priority` on `specify preset add`.
+
+The resolution is implemented three times to ensure consistency:
+- **Python**: `PresetResolver` in `src/specify_cli/presets.py`
+- **Bash**: `resolve_template()` in `scripts/bash/common.sh`
+- **PowerShell**: `Resolve-Template` in `scripts/powershell/common.ps1`
+
+## Command Registration
+
+When a preset is installed with `type: "command"` entries, the `PresetManager` registers them into all detected agent directories using the shared `CommandRegistrar` from `src/specify_cli/agents.py`.
+
+```mermaid
+flowchart TD
+    A["specify preset add my-preset"] --> B{Preset has type: command?}
+    B -- No --> Z["done (templates only)"]
+    B -- Yes --> C{Extension command?}
+    C -- "speckit.myext.cmd\n(3+ dot segments)" --> D{Extension installed?}
+    D -- No --> E["skip (extension not active)"]
+    D -- Yes --> F["register command"]
+    C -- "speckit.specify\n(core command)" --> F
+    F --> G["detect agent directories"]
+    G --> H[".claude/commands/"]
+    G --> I[".gemini/commands/"]
+    G --> J[".github/agents/"]
+    G --> K["... (17+ agents)"]
+    H --> L["write .md (Markdown format)"]
+    I --> M["write .toml (TOML format)"]
+    J --> N["write .agent.md + .prompt.md"]
+
+    style E fill:#ff5722,color:#fff
+    style L fill:#4caf50,color:#fff
+    style M fill:#4caf50,color:#fff
+    style N fill:#4caf50,color:#fff
+```
+
+### Extension safety check
+
+Command names follow the pattern `speckit.<ext-id>.<cmd-name>`. When a command has 3+ dot segments, the system extracts the extension ID and checks if `.specify/extensions/<ext-id>/` exists. If the extension isn't installed, the command is skipped — preventing orphan files referencing non-existent extensions.
+
+Core commands (e.g. `speckit.specify`, with only 2 segments) are always registered.
+
+### Agent format rendering
+
+The `CommandRegistrar` renders commands differently per agent:
+
+| Agent | Format | Extension | Arg placeholder |
+|-------|--------|-----------|-----------------|
+| Claude, Cursor, opencode, Windsurf, etc. | Markdown | `.md` | `$ARGUMENTS` |
+| Copilot | Markdown | `.agent.md` + `.prompt.md` | `$ARGUMENTS` |
+| Gemini, Qwen, Tabnine | TOML | `.toml` | `{{args}}` |
+
+### Cleanup on removal
+
+When `specify preset remove` is called, the registered commands are read from the registry metadata and the corresponding files are deleted from each agent directory, including Copilot companion `.prompt.md` files.

+# Preset Publishing Guide
+
+This guide explains how to publish your preset to the Spec Kit preset catalog, making it discoverable by `specify preset search`.
+
+## Table of Contents

+1. [Prerequisites](#prerequisites)
+2. [Prepare Your Preset](#prepare-your-preset)
+3. [Submit to Catalog](#submit-to-catalog)
+4. [Verification Process](#verification-process)
+5. [Release Workflow](#release-workflow)
+6. [Best Practices](#best-practices)
+
+---
+
+## Prerequisites
+
+Before publishing a preset, ensure you have:
+
+1. **Valid Preset**: A working preset with a valid `preset.yml` manifest
+2. **Git Repository**: Preset hosted on GitHub (or other public git hosting)
+3. **Documentation**: README.md with description and usage instructions
+4. **License**: Open source license file (MIT, Apache 2.0, etc.)
+5. **Versioning**: Semantic versioning (e.g., 1.0.0)
+6. **Testing**: Preset tested on real projects with `specify preset add --dev`
+
+---
+
+## Prepare Your Preset
+
+### 1. Preset Structure
+
+Ensure your preset follows the standard structure:
+
+```text
+your-preset/
+├── preset.yml                 # Required: Preset manifest
+├── README.md                  # Required: Documentation
+├── LICENSE                    # Required: License file
+├── CHANGELOG.md               # Recommended: Version history
+│
+├── templates/                 # Template overrides
+│   ├── spec-template.md
+│   ├── plan-template.md
+│   └── ...
+│
+└── commands/                  # Command overrides (optional)
+    └── speckit.specify.md
+```
+
+Start from the [scaffold](scaffold/) if you're creating a new preset.
+
+### 2. preset.yml Validation
+
+Verify your manifest is valid:
+
+```yaml
+schema_version: "1.0"
+
+preset:
+  id: "your-preset"               # Unique lowercase-hyphenated ID
+  name: "Your Preset Name"        # Human-readable name
+  version: "1.0.0"                # Semantic version
+  description: "Brief description (one sentence)"
+  author: "Your Name or Organization"
+  repository: "https://github.com/your-org/spec-kit-preset-your-preset"
+  license: "MIT"
+
+requires:
+  speckit_version: ">=0.1.0"      # Required spec-kit version
+
+provides:
+  templates:
+    - type: "template"
+      name: "spec-template"
+      file: "templates/spec-template.md"
+      description: "Custom spec template"
+      replaces: "spec-template"
+
+tags:                              # 2-5 relevant tags
+  - "category"
+  - "workflow"
+```
+
+**Validation Checklist**:
+
+- ✅ `id` is lowercase with hyphens only (no underscores, spaces, or special characters)
+- ✅ `version` follows semantic versioning (X.Y.Z)
+- ✅ `description` is concise (under 200 characters)
+- ✅ `repository` URL is valid and public
+- ✅ All template and command files exist in the preset directory
+- ✅ Template names are lowercase with hyphens only
+- ✅ Command names use dot notation (e.g. `speckit.specify`)
+- ✅ Tags are lowercase and descriptive
+
+### 3. Test Locally
+
+```bash
+# Install from local directory
+specify preset add --dev /path/to/your-preset
+
+# Verify templates resolve from your preset
+specify preset resolve spec-template
+
+# Verify preset info
+specify preset info your-preset
+
+# List installed presets
+specify preset list
+
+# Remove when done testing
+specify preset remove your-preset
+```
+
+If your preset includes command overrides, verify they appear in the agent directories:
+
+```bash
+# Check Claude commands (if using Claude)
+ls .claude/commands/speckit.*.md
+
+# Check Copilot commands (if using Copilot)
+ls .github/agents/speckit.*.agent.md
+
+# Check Gemini commands (if using Gemini)
+ls .gemini/commands/speckit.*.toml
+```
+
+### 4. Create GitHub Release
+
+Create a GitHub release for your preset version:
+
+```bash
+# Tag the release
+git tag v1.0.0
+git push origin v1.0.0
+```
+
+The release archive URL will be:
+
+```text
+https://github.com/your-org/spec-kit-preset-your-preset/archive/refs/tags/v1.0.0.zip
+```
+
+### 5. Test Installation from Archive
+
+```bash
+specify preset add --from https://github.com/your-org/spec-kit-preset-your-preset/archive/refs/tags/v1.0.0.zip
+```
+
+---
+
+## Submit to Catalog
+
+### Understanding the Catalogs
+
+Spec Kit uses a dual-catalog system:
+
+- **`catalog.json`** — Official, verified presets (install allowed by default)
+- **`catalog.community.json`** — Community-contributed presets (discovery only by default)
+
+All community presets should be submitted to `catalog.community.json`.
+
+### 1. Fork the spec-kit Repository
+
+```bash
+git clone https://github.com/YOUR-USERNAME/spec-kit.git
+cd spec-kit
+```
+
+### 2. Add Preset to Community Catalog
+
+Edit `presets/catalog.community.json` and add your preset.
+
+> **⚠️ Entries must be sorted alphabetically by preset ID.** Insert your preset in the correct position within the `"presets"` object.

+  }
+}
+```
+
+### 3. Submit Pull Request
+
+```bash
+git checkout -b add-your-preset
+git add presets/catalog.community.json
+git commit -m "Add your-preset to community catalog
+
+- Preset ID: your-preset
+- Version: 1.0.0
+- Author: Your Name
+- Description: Brief description
+"
+git push origin add-your-preset
+```
+
+**Pull Request Checklist**:
+
+```markdown
+## Preset Submission
+
+**Preset Name**: Your Preset Name
+**Preset ID**: your-preset
+**Version**: 1.0.0
+**Repository**: https://github.com/your-org/spec-kit-preset-your-preset
+
+### Checklist
+- [ ] Valid preset.yml manifest
+- [ ] README.md with description and usage
+- [ ] LICENSE file included
+- [ ] GitHub release created
+- [ ] Preset tested with `specify preset add --dev`
+- [ ] Templates resolve correctly (`specify preset resolve`)
+- [ ] Commands register to agent directories (if applicable)
+- [ ] Commands match template sections (command + template are coherent)
+- [ ] Added to presets/catalog.community.json
+```
+
+---
+
+## Verification Process
+
+After submission, maintainers will review:
+
+1. **Manifest validation** — valid `preset.yml`, all files exist
+2. **Template quality** — templates are useful and well-structured
+3. **Command coherence** — commands reference sections that exist in templates
+4. **Security** — no malicious content, safe file operations
+5. **Documentation** — clear README explaining what the preset does
+
+Once verified, `verified: true` is set and the preset appears in `specify preset search`.
+
+---
+
+## Release Workflow
+
+When releasing a new version:
+
+1. Update `version` in `preset.yml`
+2. Update CHANGELOG.md
+3. Tag and push: `git tag v1.1.0 && git push origin v1.1.0`
+4. Submit PR to update `version` and `download_url` in `presets/catalog.community.json`
+
+---
+
+## Best Practices
+
+### Template Design
+
+- **Keep sections clear** — use headings and placeholder text the LLM can replace
+- **Match commands to templates** — if your preset overrides a command, make sure it references the sections in your template
+- **Document customization points** — use HTML comments to guide users on what to change
+
+### Naming
+
+- Preset IDs should be descriptive: `healthcare-compliance`, `enterprise-safe`, `startup-lean`
+- Avoid generic names: `my-preset`, `custom`, `test`
+
+### Stacking
+
+- Design presets to work well when stacked with others
+- Only override templates you need to change
+- Document which templates and commands your preset modifies
+
+### Command Overrides
+
+- Only override commands when the workflow needs to change, not just the output format
+- If you only need different template sections, a template override is sufficient
+- Test command overrides with multiple agents (Claude, Gemini, Copilot)

+# Presets
+
+Presets are stackable, priority-ordered collections of template and command overrides for Spec Kit. They let you customize both the artifacts produced by the Spec-Driven Development workflow (specs, plans, tasks, checklists, constitutions) and the commands that guide the LLM in creating them — without forking or modifying core files.
+
+## How It Works
+
+When Spec Kit needs a template (e.g. `spec-template`), it walks a resolution stack:
+
+1. `.specify/templates/overrides/` — project-local one-off overrides
+2. `.specify/presets/<preset-id>/templates/` — installed presets (sorted by priority)
+3. `.specify/extensions/<ext-id>/templates/` — extension-provided templates
+4. `.specify/templates/` — core templates shipped with Spec Kit
+
+If no preset is installed, core templates are used — exactly the same behavior as before presets existed.
+
+Template resolution happens **at runtime** — although preset files are copied into `.specify/presets/<id>/` during installation, Spec Kit walks the resolution stack on every template lookup rather than merging templates into a single location.
+
+For detailed resolution and command registration flows, see [ARCHITECTURE.md](ARCHITECTURE.md).
+
+## Command Overrides
+
+Presets can also override the commands that guide the SDD workflow. Templates define *what* gets produced (specs, plans, constitutions); commands define *how* the LLM produces them (the step-by-step instructions).
+
+Unlike templates, command overrides are applied **at install time**. When a preset includes `type: "command"` entries, the commands are registered into all detected agent directories (`.claude/commands/`, `.gemini/commands/`, etc.) in the correct format (Markdown or TOML with appropriate argument placeholders). When the preset is removed, the registered commands are cleaned up.
+
+## Quick Start
+
+```bash
+# Search available presets
+specify preset search
+
+# Install a preset from the catalog
+specify preset add healthcare-compliance
+
+# Install from a local directory (for development)
+specify preset add --dev ./my-preset
+
+# Install with a specific priority (lower = higher precedence)
+specify preset add healthcare-compliance --priority 5
+
+# List installed presets
+specify preset list
+
+# See which template a name resolves to
+specify preset resolve spec-template
+
+# Get detailed info about a preset
+specify preset info healthcare-compliance
+
+# Remove a preset
+specify preset remove healthcare-compliance
+```
+
+## Stacking Presets
+
+Multiple presets can be installed simultaneously. The `--priority` flag controls which one wins when two presets provide the same template (lower number = higher precedence):
+
+```bash
+specify preset add enterprise-safe --priority 10      # base layer
+specify preset add healthcare-compliance --priority 5  # overrides enterprise-safe
+specify preset add pm-workflow --priority 1            # overrides everything
+```
+
+Presets **override**, they don't merge. If two presets both provide `spec-template`, the one with the lowest priority number wins entirely.
+
+## Catalog Management
+
+Presets are discovered through catalogs. By default, Spec Kit uses the official and community catalogs:
+
+> [!NOTE]
+> Community presets are independently created and maintained by their respective authors. GitHub and the Spec Kit maintainers may review pull requests that add entries to the community catalog for formatting, catalog structure, or policy compliance, but they do **not review, audit, endorse, or support the preset code itself**. Review preset source code before installation and use at your own discretion.
+
+```bash
+# List active catalogs
+specify preset catalog list
+
+# Add a custom catalog
+specify preset catalog add https://example.com/catalog.json --name my-org --install-allowed
+
+# Remove a catalog
+specify preset catalog remove my-org
+```
+
+## Creating a Preset
+
+See [scaffold/](scaffold/) for a scaffold you can copy to create your own preset.
+
+1. Copy `scaffold/` to a new directory
+2. Edit `preset.yml` with your preset's metadata
+3. Add or replace templates in `templates/`
+4. Test locally with `specify preset add --dev .`
+5. Verify with `specify preset resolve spec-template`
+
+## Environment Variables
+
+| Variable | Description |
+|----------|-------------|
+| `SPECKIT_PRESET_CATALOG_URL` | Override the catalog URL (replaces all defaults) |
+
+## Configuration Files
+
+| File | Scope | Description |
+|------|-------|-------------|
+| `.specify/preset-catalogs.yml` | Project | Custom catalog stack for this project |
+| `~/.specify/preset-catalogs.yml` | User | Custom catalog stack for all projects |
+
+## Future Considerations
+
+The following enhancements are under consideration for future releases:
+
+- **Composition strategies** — Allow presets to declare a `strategy` per template instead of the default `replace`:
+
+  | Type | `replace` | `prepend` | `append` | `wrap` |
+  |------|-----------|-----------|----------|--------|
+  | **template** | ✓ (default) | ✓ | ✓ | ✓ |
+  | **command** | ✓ (default) | ✓ | ✓ | ✓ |
+  | **script** | ✓ (default) | — | — | ✓ |
+
+  For artifacts and commands (which are LLM directives), `wrap` would inject preset content before and after the core template using a `{CORE_TEMPLATE}` placeholder. For scripts, `wrap` would run custom logic before/after the core script via a `$CORE_SCRIPT` variable.
+- **Script overrides** — Enable presets to provide alternative versions of core scripts (e.g. `create-new-feature.sh`) for workflow customization. A `strategy: "wrap"` option could allow presets to run custom logic before/after the core script without fully replacing it.
