+# 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+.

-## General practices
+## Integration Architecture
 
-- Any changes to `__init__.py` for the Specify CLI require a version rev in `pyproject.toml` and addition of entries to `CHANGELOG.md`.
+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()`.

-This section explains how to add support for new AI agents/assistants to the Specify CLI. Use this guide as a reference when integrating new AI tools into the Spec-Driven Development workflow.
+The registry is the **single source of truth for Python integration metadata**. Supported agents, their directories, formats, capabilities, and context files are derived from the integration classes for the Python integration layer.
 
-### Overview
+---
 
-Specify supports multiple AI agents by generating agent-specific command files and directory structures when initializing projects. Each agent has its own conventions for:
+## Adding a New Integration
 
-- **Command file formats** (Markdown, TOML, etc.)
-- **Directory structures** (`.claude/commands/`, `.windsurf/workflows/`, etc.)
-- **Command invocation patterns** (slash commands, CLI tools, etc.)
-- **Argument passing conventions** (`$ARGUMENTS`, `{{args}}`, etc.)
+### 1. Choose a base class
 
-### Current Supported Agents
+| 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 |
 
-| Agent | Directory | Format | CLI Tool | Description |
-|-------|-----------|---------|----------|-------------|
-| **Claude Code** | `.claude/commands/` | Markdown | `claude` | Anthropic's Claude Code CLI |
-| **Gemini CLI** | `.gemini/commands/` | TOML | `gemini` | Google's Gemini CLI |
-| **GitHub Copilot** | `.github/prompts/` | Markdown | N/A (IDE-based) | GitHub Copilot in VS Code |
-| **Cursor** | `.cursor/commands/` | Markdown | `cursor-agent` | Cursor CLI |
-| **Qwen Code** | `.qwen/commands/` | TOML | `qwen` | Alibaba's Qwen Code CLI |
-| **opencode** | `.opencode/command/` | Markdown | `opencode` | opencode CLI |
-| **Codex CLI** | `.codex/commands/` | Markdown | `codex` | Codex CLI |
-| **Windsurf** | `.windsurf/workflows/` | Markdown | N/A (IDE-based) | Windsurf IDE workflows |
-| **Kilo Code** | `.kilocode/rules/` | Markdown | N/A (IDE-based) | Kilo Code IDE |
-| **Auggie CLI** | `.augment/rules/` | Markdown | `auggie` | Auggie CLI |
-| **Roo Code** | `.roo/rules/` | Markdown | N/A (IDE-based) | Roo Code IDE |
-| **CodeBuddy CLI** | `.codebuddy/commands/` | Markdown | `codebuddy` | CodeBuddy CLI |
-| **Amazon Q Developer CLI** | `.amazonq/prompts/` | Markdown | `q` | Amazon Q Developer CLI |
+Most agents only need `MarkdownIntegration` — a minimal subclass with zero method overrides.
 
-### Step-by-Step Integration Guide
+### 2. Create the subpackage
 
-Follow these steps to add a new agent (using a hypothetical new agent as an example):
+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.
 
-#### 1. Add to AGENT_CONFIG
-
-**IMPORTANT**: Use the actual CLI tool name as the key, not a shortened version.
-
-Add the new agent to the `AGENT_CONFIG` dictionary in `src/specify_cli/__init__.py`. This is the **single source of truth** for all agent metadata:
+**Minimal example — Markdown agent (Windsurf):**
 
 ```python
-AGENT_CONFIG = {
-    # ... existing agents ...
-    "new-agent-cli": {  # Use the ACTUAL CLI tool name (what users type in terminal)
-        "name": "New Agent Display Name",
-        "folder": ".newagent/",  # Directory for agent files
-        "install_url": "https://example.com/install",  # URL for installation docs (or None if IDE-based)
-        "requires_cli": True,  # True if CLI tool required, False for IDE-based agents
-    },
-}
-```
+"""Windsurf IDE integration."""
 
-**Key Design Principle**: The dictionary key should match the actual executable name that users install. For example:
-- ✅ Use `"cursor-agent"` because the CLI tool is literally called `cursor-agent`
-- ❌ Don't use `"cursor"` as a shortcut if the tool is `cursor-agent`
+from ..base import MarkdownIntegration
 
-This eliminates the need for special-case mappings throughout the codebase.
 
-**Field Explanations**:
-- `name`: Human-readable display name shown to users
-- `folder`: Directory where agent-specific files are stored (relative to project root)
-- `install_url`: Installation documentation URL (set to `None` for IDE-based agents)
-- `requires_cli`: Whether the agent requires a CLI tool check during initialization
-
-#### 2. Update CLI Help Text
-
-Update the `--ai` parameter help text in the `init()` command to include the new agent:
-
-```python
-ai_assistant: str = typer.Option(None, "--ai", help="AI assistant to use: claude, gemini, copilot, cursor-agent, qwen, opencode, codex, windsurf, kilocode, auggie, codebuddy, new-agent-cli, or q"),
-```
-
-Also update any function docstrings, examples, and error messages that list available agents.
-
-#### 3. Update README Documentation
-
-Update the **Supported AI Agents** section in `README.md` to include the new agent:
-
-- Add the new agent to the table with appropriate support level (Full/Partial)
-- Include the agent's official website link
-- Add any relevant notes about the agent's implementation
-- Ensure the table formatting remains aligned and consistent
-
-#### 4. Update Release Package Script
-
-Modify `.github/workflows/scripts/create-release-packages.sh`:
-
-##### Add to ALL_AGENTS array:
-```bash
-ALL_AGENTS=(claude gemini copilot cursor-agent qwen opencode windsurf q)
-```
-
-##### Add case statement for directory structure:
-```bash
-case $agent in
-  # ... existing cases ...
-  windsurf)
-    mkdir -p "$base_dir/.windsurf/workflows"
-    generate_commands windsurf md "\$ARGUMENTS" "$base_dir/.windsurf/workflows" "$script" ;;
-esac
-```
-
-#### 4. Update GitHub Release Script
-
-Modify `.github/workflows/scripts/create-github-release.sh` to include the new agent's packages:
-
-```bash
-gh release create "$VERSION" \
-  # ... existing packages ...
-  .genreleases/spec-kit-template-windsurf-sh-"$VERSION".zip \
-  .genreleases/spec-kit-template-windsurf-ps-"$VERSION".zip \
-  # Add new agent packages here
-```
-
-#### 5. Update Agent Context Scripts
-
-##### Bash script (`scripts/bash/update-agent-context.sh`):
-
-Add file variable:
-```bash
-WINDSURF_FILE="$REPO_ROOT/.windsurf/rules/specify-rules.md"
-```
-
-Add to case statement:
-```bash
-case "$AGENT_TYPE" in
-  # ... existing cases ...
-  windsurf) update_agent_file "$WINDSURF_FILE" "Windsurf" ;;
-  "") 
-    # ... existing checks ...
-    [ -f "$WINDSURF_FILE" ] && update_agent_file "$WINDSURF_FILE" "Windsurf";
-    # Update default creation condition
-    ;;
-esac
-```
-
-##### PowerShell script (`scripts/powershell/update-agent-context.ps1`):
-
-Add file variable:
-```powershell
-$windsurfFile = Join-Path $repoRoot '.windsurf/rules/specify-rules.md'
-```
-
-Add to switch statement:
-```powershell
-switch ($AgentType) {
-    # ... existing cases ...
-    'windsurf' { Update-AgentFile $windsurfFile 'Windsurf' }
-    '' {
-        foreach ($pair in @(
-            # ... existing pairs ...
-            @{file=$windsurfFile; name='Windsurf'}
-        )) {
-            if (Test-Path $pair.file) { Update-AgentFile $pair.file $pair.name }
-        }
-        # Update default creation condition
+class WindsurfIntegration(MarkdownIntegration):
+    key = "windsurf"
+    config = {
+        "name": "Windsurf",
+        "folder": ".windsurf/",
+        "commands_subdir": "workflows",
+        "install_url": None,
+        "requires_cli": False,
     }
-}
-```
-
-#### 6. Update CLI Tool Checks (Optional)
-
-For agents that require CLI tools, add checks in the `check()` command and agent validation:
-
-```python
-# In check() command
-tracker.add("windsurf", "Windsurf IDE (optional)")
-windsurf_ok = check_tool_for_tracker("windsurf", "https://windsurf.com/", tracker)
-
-# In init validation (only if CLI tool required)
-elif selected_ai == "windsurf":
-    if not check_tool("windsurf", "Install from: https://windsurf.com/"):
-        console.print("[red]Error:[/red] Windsurf CLI is required for Windsurf projects")
-        agent_tool_missing = True
-```
-
-**Note**: CLI tool checks are now handled automatically based on the `requires_cli` field in AGENT_CONFIG. No additional code changes needed in the `check()` or `init()` commands - they automatically loop through AGENT_CONFIG and check tools as needed.
-
-## Important Design Decisions
-
-### Using Actual CLI Tool Names as Keys
-
-**CRITICAL**: When adding a new agent to AGENT_CONFIG, always use the **actual executable name** as the dictionary key, not a shortened or convenient version.
-
-**Why this matters:**
-- The `check_tool()` function uses `shutil.which(tool)` to find executables in the system PATH
-- If the key doesn't match the actual CLI tool name, you'll need special-case mappings throughout the codebase
-- This creates unnecessary complexity and maintenance burden
-
-**Example - The Cursor Lesson:**
-
-❌ **Wrong approach** (requires special-case mapping):
-```python
-AGENT_CONFIG = {
-    "cursor": {  # Shorthand that doesn't match the actual tool
-        "name": "Cursor",
-        # ...
+    registrar_config = {
+        "dir": ".windsurf/workflows",
+        "format": "markdown",
+        "args": "$ARGUMENTS",
+        "extension": ".md",
     }
-}
-
-# Then you need special cases everywhere:
-cli_tool = agent_key
-if agent_key == "cursor":
-    cli_tool = "cursor-agent"  # Map to the real tool name
+    context_file = ".windsurf/rules/specify-rules.md"
 ```
 
-✅ **Correct approach** (no mapping needed):
+**TOML agent (Gemini):**
+
 ```python
-AGENT_CONFIG = {
-    "cursor-agent": {  # Matches the actual executable name
-        "name": "Cursor",
-        # ...
-    }
-}
+"""Gemini CLI integration."""
 
-# No special cases needed - just use agent_key directly!
+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"
 ```
 
-**Benefits of this approach:**
-- Eliminates special-case logic scattered throughout the codebase
-- Makes the code more maintainable and easier to understand
-- Reduces the chance of bugs when adding new agents
-- Tool checking "just works" without additional mappings
+**Skills agent (Codex):**

-### IDE-Based Agents

+
+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. Context file behavior
+
+Set `context_file` on the integration class. The base integration setup creates or updates the managed Spec Kit section in that file, and uninstall removes the managed section when appropriate.
+
+Only add custom setup logic when the agent needs non-standard behavior. Most integrations do not need wrapper scripts or separate context-update dispatch code.
+
+### 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, Copilot → `--skills` flag |
+| `setup()` | Custom install logic (companion files, settings merge) | Copilot → `.agent.md` + `.prompt.md` + `.vscode/settings.json` (default) or `speckit-<name>/SKILL.md` (skills mode) |
+| `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`. It also supports a `--skills` mode that scaffolds `speckit-<name>/SKILL.md` under `.github/skills/` using composition with an internal `_CopilotSkillsHelper`. 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"
+```

 ## Argument Patterns
 
-Different agents use different argument placeholders:
-- **Markdown/prompt-based**: `$ARGUMENTS`
-- **TOML-based**: `{{args}}`
+Different agents use different argument placeholders. The placeholder used in command files is always taken from `registrar_config["args"]` for each integration — check there first when in doubt:
+
+- **Markdown/prompt-based**: `$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)

-2. **CLI test**: Test `specify init --ai <agent>` command
-3. **File generation**: Verify correct directory structure and files
-4. **Command validation**: Ensure generated commands work with the agent
-5. **Context update**: Test agent context update scripts
+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
+
+**Skills mode (`--skills`):** Copilot also supports an alternative skills-based layout
+via `--integration-options="--skills"`. When enabled:
+- Commands are scaffolded as `speckit-<name>/SKILL.md` under `.github/skills/`
+- No companion `.prompt.md` files are generated
+- No `.vscode/settings.json` merge
+- `post_process_skill_content()` injects a `mode: speckit.<stem>` frontmatter field
+- `build_command_invocation()` returns `/speckit-<stem>` instead of bare args
+
+The two modes are mutually exclusive — a project uses one or the other:
+
+```bash
+# Default mode: .agent.md agents + .prompt.md companions + settings merge
+specify init my-project --integration copilot
+
+# Skills mode: speckit-<name>/SKILL.md under .github/skills/
+specify init my-project --integration copilot --integration-options="--skills"
+```
+
+### 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
+
+### 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. Sets `context_file = "AGENTS.md"` so the base setup manages the Spec Kit context section there
 
 ## Common Pitfalls
 
-1. **Using shorthand keys instead of actual CLI tool names**: Always use the actual executable name as the AGENT_CONFIG key (e.g., `"cursor-agent"` not `"cursor"`). This prevents the need for special-case mappings throughout the codebase.
-2. **Forgetting update scripts**: Both bash and PowerShell scripts must be updated when adding new agents.
-3. **Incorrect `requires_cli` value**: Set to `True` only for agents that actually have CLI tools to check; set to `False` for IDE-based agents.
-4. **Wrong argument format**: Use correct placeholder format for each agent type (`$ARGUMENTS` for Markdown, `{{args}}` for TOML).
-5. **Directory naming**: Follow agent-specific conventions exactly (check existing agents for patterns).
-6. **Help text inconsistency**: Update all user-facing text consistently (help strings, docstrings, README, error messages).
-
-## Future Considerations
-
-When adding new agents:
-
-- Consider the agent's native command/workflow patterns
-- Ensure compatibility with the Spec-Driven Development process
-- Document any special requirements or limitations
-- Update this guide with lessons learned
-- Verify the actual CLI tool name before adding to AGENT_CONFIG
+1. **Using shorthand keys for CLI-based integrations**: For CLI-based integrations (`requires_cli: True`), the `key` must match the executable name (e.g., `"cursor-agent"` not `"cursor"`). `shutil.which(key)` is used for CLI tool checks — mismatches require special-case mappings. IDE-based integrations (`requires_cli: False`) are not subject to this constraint.
+2. **Forgetting update scripts**: Both bash and PowerShell thin wrappers and the shared context-update scripts must be updated.
+3. **Incorrect `requires_cli` value**: Set to `True` only for agents that have a CLI tool; set to `False` for IDE-based agents.
+4. **Wrong argument format**: Use `$ARGUMENTS` for Markdown agents, `{{args}}` for TOML agents.
+5. **Skipping registration**: The import and `_register()` call in `_register_builtins()` must both be added.

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

+#### Agent configuration and wiring consistency
+
+```bash
+uv run python -m pytest tests/test_agent_config_consistency.py -q

+#### Manual testing process
+
+Any change that affects a slash command's behavior requires manually testing that command through a coding agent and submitting results with the PR.
+
+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 [Testing setup](#testing-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.

+
+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 CONTRIBUTING.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).

+
+## 🧩 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 reference](https://github.github.io/spec-kit/reference/extensions.html) for the full command guide. 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 reference](https://github.github.io/spec-kit/reference/presets.html) for the full command guide, including resolution order and priority stacking.
+
+### 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

+
+- **[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 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.

+# Installing uv
+
+[uv](https://docs.astral.sh/uv/) is a fast Python package manager by [Astral](https://astral.sh/). Spec Kit uses `uv` (via `uvx` or `uv tool install`) to run the `specify` CLI without polluting your global Python environment.
+
+> [!NOTE]
+> **Already have uv?** Run `uv --version` to confirm it is installed, then head back to the [Installation Guide](../installation.md).
+
+## Installation
+
+### macOS and Linux — Standalone Installer
+
+The quickest way to install uv on macOS or Linux is the official shell script:
+
+```bash
+curl -LsSf https://astral.sh/uv/install.sh | sh
+```
+
+After the script finishes, follow any instructions printed by the installer to add uv to your `PATH`, then open a new terminal.
+
+### Windows — Standalone Installer
+
+Run the following in **Command Prompt or PowerShell**:
+
+```powershell
+powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
+```
+
+After the script finishes, open a new terminal so the `uv` binary is on your `PATH`.
+
+### macOS — Homebrew
+
+```bash
+brew install uv
+```
+
+### Windows — WinGet
+
+```powershell
+winget install --id=astral-sh.uv -e
+```
+
+### Windows — Scoop
+
+```powershell
+scoop install uv
+```
+
+## Verification
+
+Confirm that uv is installed and on your `PATH`:
+
+```bash
+uv --version
+```
+
+You should see output similar to `uv 0.x.y (...)`.
+
+## Further Reading
+
+For advanced options (self-update, proxy settings, uninstall, etc.) see the official [uv installation docs](https://docs.astral.sh/uv/getting-started/installation/).

 ## 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

-## The 4-Step Process
+## The 6-Step Process
 
-### 1. Install Specify
+> [!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.
 
-Initialize your project depending on the coding agent you're using:
+### 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 .
 ```
 
+> [!NOTE]
+> You can also install the CLI persistently with `pipx`:
+> ```bash
+> pipx install git+https://github.com/github/spec-kit.git
+> ```
+> After installing with `pipx`, run `specify` directly instead of `uvx --from ... specify`, for example:
+> ```bash
+> specify init <PROJECT_NAME>
+> 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
 ```
 
-### 2. Create the Spec
+### Step 2: Define Your Constitution
 
-Use the `/speckit.specify` command to describe what you want to build. Focus on the **what** and **why**, not the tech stack.
+**In your coding 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.
 
-```bash
+```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.
 ```
 
-### 3. Create a Technical Implementation Plan
+### Step 4: Refine the Spec
 
-Use the `/speckit.plan` command to provide your tech stack and architecture choices.
+**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.
 ```
 
-### 4. Break Down and Implement
+### Step 6: Break Down and Implement
 
-Use `/speckit.tasks` to create an actionable task list, then ask your agent to implement the feature.
+**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.

+# Authentication
+
+Specify CLI uses **opt-in authentication** for HTTP requests to catalog
+sources, extension downloads, and release checks.  No credentials are
+sent unless you explicitly configure them.
+
+## Configuration
+
+Create `~/.specify/auth.json` to enable authentication:
+
+```json
+{
+  "providers": [
+    {
+      "hosts": ["github.com", "api.github.com", "raw.githubusercontent.com", "codeload.github.com"],
+      "provider": "github",
+      "auth": "bearer",
+      "token_env": "GH_TOKEN"
+    }
+  ]
+}
+```
+
+> **Security:** Restrict the file to owner-only access:
+> ```bash
+> chmod 600 ~/.specify/auth.json
+> ```
+
+Without this file, all HTTP requests are unauthenticated.
+
+## Fields
+
+Each entry in the `providers` array has the following fields:
+
+| Field | Required | Description |
+|---|---|---|
+| `hosts` | Yes | Array of hostnames this entry applies to. Supports exact hostnames, or a leading `*.` wildcard for subdomains only (for example, `*.visualstudio.com`). `*.visualstudio.com` matches `foo.visualstudio.com`, but not `visualstudio.com`. Other glob patterns such as `*github.com` or `gith?b.com` are not supported. |
+| `provider` | Yes | Built-in provider key: `github` or `azure-devops`. |
+| `auth` | Yes | Auth scheme (see below). |
+| `token` | No | Token value (inline). Use `token_env` instead when possible. |
+| `token_env` | No | Environment variable name to read the token from. |
+
+For `azure-ad` auth, additional fields are required:
+
+| Field | Required | Description |
+|---|---|---|
+| `tenant_id` | Yes | Azure AD tenant ID. |
+| `client_id` | Yes | Service principal client ID. |
+| `client_secret_env` | Yes | Environment variable containing the client secret. |
+
+Either `token` or `token_env` must be set for `bearer` and `basic-pat` schemes.
+
+## Providers and auth schemes
+
+### GitHub (`github`)
+
+| Scheme | Header | Use for |
+|---|---|---|
+| `bearer` | `Authorization: Bearer <token>` | PATs, fine-grained PATs, OAuth tokens, GitHub App tokens |
+
+**Example — PAT via environment variable:**
+
+```json
+{
+  "hosts": ["github.com", "api.github.com", "raw.githubusercontent.com", "codeload.github.com"],
+  "provider": "github",
+  "auth": "bearer",
+  "token_env": "GH_TOKEN"
+}
+```
+
+### Azure DevOps (`azure-devops`)
+
+| Scheme | Header | Use for |
+|---|---|---|
+| `basic-pat` | `Authorization: Basic base64(:<PAT>)` | Personal Access Tokens |
+| `bearer` | `Authorization: Bearer <token>` | Pre-acquired OAuth / Azure AD tokens |
+| `azure-cli` | `Authorization: Bearer <token>` | Token acquired via `az account get-access-token` |
+| `azure-ad` | `Authorization: Bearer <token>` | Token acquired via OAuth2 client credentials flow |
+
+**Example — PAT via environment variable:**
+
+```json
+{
+  "hosts": ["dev.azure.com"],
+  "provider": "azure-devops",
+  "auth": "basic-pat",
+  "token_env": "AZURE_DEVOPS_PAT"
+}
+```
+
+**Example — Azure CLI (interactive login):**
+
+```json
+{
+  "hosts": ["dev.azure.com"],
+  "provider": "azure-devops",
+  "auth": "azure-cli"
+}
+```
+
+Requires `az login` to have been run beforehand.
+
+**Example — Azure AD service principal (CI/automation):**
+
+```json
+{
+  "hosts": ["dev.azure.com"],
+  "provider": "azure-devops",
+  "auth": "azure-ad",
+  "tenant_id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
+  "client_id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
+  "client_secret_env": "AZURE_CLIENT_SECRET"
+}
+```
+
+## Multiple entries
+
+You can configure multiple entries for different hosts or organizations:
+
+```json
+{
+  "providers": [
+    {
+      "hosts": ["github.com", "api.github.com", "raw.githubusercontent.com", "codeload.github.com"],
+      "provider": "github",
+      "auth": "bearer",
+      "token_env": "GH_TOKEN"
+    },
+    {
+      "hosts": ["dev.azure.com"],
+      "provider": "azure-devops",
+      "auth": "basic-pat",
+      "token_env": "AZURE_DEVOPS_PAT"
+    }
+  ]
+}
+```
+
+## How it works
+
+1. For each outbound HTTP request, the URL hostname is matched against
+   the `hosts` patterns in `auth.json`.
+2. If a match is found, the corresponding provider resolves the token
+   and attaches the appropriate `Authorization` header.
+3. If the request receives a 401 or 403, the next matching entry is tried.
+4. After all matching entries are exhausted, an unauthenticated request
+   is attempted as a final fallback.
+5. On redirects, the `Authorization` header is stripped if the redirect
+   target leaves the entry's declared hosts — preventing credential
+   leakage to CDNs or third-party services.
+
+## Template
+
+A reference `auth.json` with GitHub pre-configured:
+
+```json
+{
+  "providers": [
+    {
+      "hosts": [

+      "provider": "github",
+      "auth": "bearer",
+      "token_env": "GH_TOKEN"

+| ------------------------ | ------------------------------------------------------------------------ |
+| `--integration <key>`    | AI coding agent integration to use (e.g. `copilot`, `claude`, `gemini`). See the [Integrations reference](integrations.md) for all available keys |
+| `--integration-options`  | Options for the integration (e.g. `--integration-options="--commands-dir .myagent/cmds"`) |
+| `--script sh\|ps`        | Script type: `sh` (bash/zsh) or `ps` (PowerShell)                       |
+| `--here`                 | Initialize in the current directory instead of creating a new one        |
+| `--force`                | Force merge/overwrite when initializing in an existing directory         |
+| `--no-git`               | Skip git repository initialization                                       |
+| `--ignore-agent-tools`   | Skip checks for AI coding agent CLI tools                                |
+| `--preset <id>`          | Install a preset during initialization                                   |
+| `--branch-numbering`     | Branch numbering strategy: `sequential` (default) or `timestamp`         |
+
+Creates a new Spec Kit project with the necessary directory structure, templates, scripts, and AI coding agent integration files.
+
+> [!NOTE]
+> The git extension is currently enabled by default during `specify init`.
+> Starting in `v0.10.0`, it will require explicit opt-in. To add it after init, run `specify extension add git`.
+
+Use `<project_name>` to create a new directory, or `--here` (or `.`) to initialize in the current directory. If the directory already has files, use `--force` to merge without confirmation.
+
+When `--integration` is omitted, interactive terminals prompt you to choose an integration. Non-interactive sessions, such as CI or piped runs, default to GitHub Copilot; pass `--integration <key>` to choose a different integration explicitly.
+
+### Examples
+
+```bash
+# Create a new project with an integration
+specify init my-project --integration copilot
+
+# Initialize in the current directory
+specify init --here --integration copilot
+
+# Force merge into a non-empty directory
+specify init --here --force --integration copilot
+
+# Use PowerShell scripts (Windows/cross-platform)
+specify init my-project --integration copilot --script ps
+
+# Skip git initialization
+specify init my-project --integration copilot --no-git
+
+# Install a preset during initialization
+specify init my-project --integration copilot --preset compliance
+
+# Use timestamp-based branch numbering (useful for distributed teams)
+specify init my-project --integration copilot --branch-numbering timestamp

+| `SPECIFY_FEATURE` | Override feature detection for non-Git repositories. Set to the feature directory name (e.g., `001-photo-albums`) to work on a specific feature when not using Git branches. Must be set in the context of the agent prior to using `/speckit.plan` or follow-up commands. |
+
+## Check Installed Tools
+
+```bash
+specify check
+```
+
+Checks that required tools are available on your system: `git` and any CLI-based AI coding agents. IDE-based agents are skipped since they don't require a CLI tool.

+# Extensions
+
+Extensions add new capabilities to Spec Kit — domain-specific commands, external tool integrations, quality gates, and more. They introduce new commands and templates that go beyond the built-in Spec-Driven Development workflow.
+
+## Search Available Extensions
+
+```bash
+specify extension search [query]
+```
+
+| Option       | Description                          |
+| ------------ | ------------------------------------ |
+| `--tag`      | Filter by tag                        |
+| `--author`   | Filter by author                     |
+| `--verified` | Show only verified extensions        |
+
+Searches all active catalogs for extensions matching the query. Without a query, lists all available extensions.
+
+## Install an Extension
+
+```bash
+specify extension add <name>
+```
+
+| Option          | Description                                              |
+| --------------- | -------------------------------------------------------- |
+| `--dev`         | Install from a local directory (for development)         |
+| `--from <url>`  | Install from a custom URL instead of the catalog         |
+| `--priority <N>`| Resolution priority (default: 10; lower = higher precedence) |
+
+Installs an extension from the catalog, a URL, or a local directory. Extension commands are automatically registered with the currently installed AI coding agent integration.
+
+> **Note:** All extension commands require a project already initialized with `specify init`.
+
+## Remove an Extension
+
+```bash
+specify extension remove <name>
+```
+
+| Option          | Description                                    |
+| --------------- | ---------------------------------------------- |
+| `--keep-config` | Preserve configuration files during removal    |
+| `--force`       | Skip confirmation prompt                       |
+
+Removes an installed extension. Configuration files are backed up by default; use `--keep-config` to leave them in place or `--force` to skip the confirmation.
+
+## List Installed Extensions
+
+```bash
+specify extension list
+```
+
+| Option        | Description                                        |
+| ------------- | -------------------------------------------------- |
+| `--available` | Show available (uninstalled) extensions            |
+| `--all`       | Show both installed and available extensions       |
+
+Lists installed extensions with their status, version, and command counts.
+
+## Extension Info
+
+```bash
+specify extension info <name>
+```
+
+Shows detailed information about an installed or available extension, including its description, version, commands, and configuration.
+
+## Update Extensions
+
+```bash
+specify extension update [<name>]
+```
+
+Updates a specific extension, or all installed extensions if no name is given.
+
+## Enable / Disable an Extension
+
+```bash
+specify extension enable <name>
+specify extension disable <name>
+```
+
+Disable an extension without removing it. Disabled extensions are not loaded and their commands are not available. Re-enable with `enable`.
+
+## Set Extension Priority
+
+```bash
+specify extension set-priority <name> <priority>
+```
+
+Changes the resolution priority of an extension. When multiple extensions provide a command with the same name, the extension with the lowest priority number takes precedence.
+
+## Catalog Management
+
+Extension catalogs control where `search` and `add` look for extensions. Catalogs are checked in priority order (lower number = higher precedence).
+
+### List Catalogs
+
+```bash
+specify extension catalog list
+```
+
+Shows all active catalogs in the stack with their priorities and install permissions.
+
+### Add a Catalog
+
+```bash
+specify extension catalog add <url>
+```
+
+| Option                               | Description                                        |
+| ------------------------------------ | -------------------------------------------------- |
+| `--name <name>`                      | Required. Unique name for the catalog              |
+| `--priority <N>`                     | Priority (default: 10; lower = higher precedence)  |
+| `--install-allowed / --no-install-allowed` | Whether extensions can be installed from this catalog |
+| `--description <text>`               | Optional description                               |
+
+Adds a catalog to the project's `.specify/extension-catalogs.yml`.
+
+### Remove a Catalog
+
+```bash
+specify extension catalog remove <name>
+```
+
+Removes a catalog from the project configuration.
+
+### Catalog Resolution Order
+
+Catalogs are resolved in this order (first match wins):
+
+1. **Environment variable** — `SPECKIT_CATALOG_URL` overrides all catalogs
+2. **Project config** — `.specify/extension-catalogs.yml`
+3. **User config** — `~/.specify/extension-catalogs.yml`
+4. **Built-in defaults** — official catalog + community catalog
+
+Example `.specify/extension-catalogs.yml`:
+
+```yaml
+catalogs:
+  - name: "my-org-catalog"
+    url: "https://example.com/catalog.json"
+    priority: 5
+    install_allowed: true
+    description: "Our approved extensions"
+```
+
+## Extension Configuration
+
+Most extensions include configuration files in their install directory:
+
+```text
+.specify/extensions/<ext>/
+├── <ext>-config.yml           # Project config (version controlled)
+├── <ext>-config.local.yml     # Local overrides (gitignored)
+└── <ext>-config.template.yml  # Template reference
+```
+
+Configuration is merged in this order (highest priority last):
+
+1. **Extension defaults** (from `extension.yml`)
+2. **Project config** (`<ext>-config.yml`)
+3. **Local overrides** (`<ext>-config.local.yml`)
+4. **Environment variables** (`SPECKIT_<EXT>_*`)
+
+To set up configuration for a newly installed extension, copy the template:
+
+```bash
+cp .specify/extensions/<ext>/<ext>-config.template.yml \
+   .specify/extensions/<ext>/<ext>-config.yml
+```
+
+## FAQ
+
+### Why can't I find an extension with `search`?
+
+Check the spelling of the extension name. The extension may not be published yet, or it may be in a catalog you haven't added. Use `specify extension catalog list` to see which catalogs are active.
+
+### Why doesn't the extension command appear in my AI coding agent?
+
+Verify the extension is installed and enabled with `specify extension list`. If it shows as installed, restart your AI coding agent — it may need to reload for it to take effect.
+
+### How do I set up extension configuration?
+
+Copy the config template that ships with the extension:
+
+```bash
+cp .specify/extensions/<ext>/<ext>-config.template.yml \
+   .specify/extensions/<ext>/<ext>-config.yml
+```
+
+See [Extension Configuration](#extension-configuration) for details on config layers and overrides.
+
+### How do I resolve an incompatible version error?
+
+Update Spec Kit to the version required by the extension.
+
+### Who maintains extensions?
+
+Most extensions are independently created and maintained by their respective authors. The Spec Kit maintainers do not review, audit, endorse, or support extension code. Review an extension's source code before installing and use at your own discretion. For issues with a specific extension, contact its author or file an issue on the extension's repository.

+# Supported AI Coding Agent Integrations
+
+The Specify CLI supports a wide range of AI coding agents. When you run `specify init`, the CLI sets up the appropriate command files, context rules, and directory structures for your chosen AI coding agent — so you can start using Spec-Driven Development immediately, regardless of which tool you prefer.

+
+## List Available Integrations
+
+```bash
+specify integration list
+```
+
+Shows all available integrations, which one is currently installed, and whether each requires a CLI tool or is IDE-based.
+When multiple integrations are installed, the list marks the default integration separately from the other installed integrations.
+The list also shows whether each built-in integration is declared multi-install safe.
+
+## Install an Integration
+
+```bash
+specify integration install <key>
+```
+
+| Option                   | Description                                                              |
+| ------------------------ | ------------------------------------------------------------------------ |
+| `--script sh\|ps`        | Script type: `sh` (bash/zsh) or `ps` (PowerShell)                        |
+| `--force`                | Opt in to installing alongside integrations that are not declared multi-install safe |
+| `--integration-options`  | Integration-specific options (e.g. `--integration-options="--commands-dir .myagent/cmds"`) |
+
+Installs the specified integration into the current project. If another integration is already installed, the command only proceeds automatically when all involved integrations are declared multi-install safe. Otherwise, use `switch` to replace the default integration or pass `--force` to explicitly opt in to multi-install. If the installation fails partway through, it automatically rolls back to a clean state.
+
+Installing an additional integration does not change the default integration. Use `specify integration use <key>` to change the default.
+
+> **Note:** All integration management commands require a project already initialized with `specify init`. To start a new project with a specific agent, use `specify init <project> --integration <key>` instead.
+
+## Uninstall an Integration
+
+```bash
+specify integration uninstall [<key>]
+```
+
+| Option    | Description                                         |
+| --------- | --------------------------------------------------- |
+| `--force` | Remove files even if they have been modified         |
+
+Uninstalls the current integration (or the specified one). Spec Kit tracks every file created during install along with a SHA-256 hash of the original content:
+
+- **Unmodified files** are removed automatically.
+- **Modified files** (where you've made manual edits) are preserved so your customizations are not lost.
+- Use `--force` to remove all integration files regardless of modifications.
+
+## Switch to a Different Integration
+
+```bash
+specify integration switch <key>
+```
+
+| Option                   | Description                                                              |
+| ------------------------ | ------------------------------------------------------------------------ |
+| `--script sh\|ps`        | Script type: `sh` (bash/zsh) or `ps` (PowerShell)                        |
+| `--force`                | Force removal of modified files during uninstall; when the target is already installed, overwrite managed shared templates while changing the default |
+| `--integration-options`  | Options for the target integration when it is not already installed      |
+
+If the target integration is not already installed, equivalent to running `uninstall` followed by `install` in a single step. In this mode, `--force` controls whether modified files from the removed integration are deleted. If the target integration is already installed, `switch` only changes the default integration, like `use`; in this mode, `--force` controls whether managed shared templates are overwritten while the default changes. `--integration-options` is rejected for already-installed targets because changing integration options requires reinstalling managed files; run `upgrade <key> --integration-options ...` first, then `use <key>`.
+
+## Use an Installed Integration
+
+```bash
+specify integration use <key>
+```
+
+| Option    | Description                                         |
+| --------- | --------------------------------------------------- |
+| `--force` | Overwrite managed shared templates while changing the default |
+
+Sets the default integration without uninstalling any other installed integrations. This also refreshes managed shared templates so command references match the new default integration's invocation style. Modified or untracked shared templates are preserved unless `--force` is used.
+
+## Upgrade an Integration
+
+```bash
+specify integration upgrade [<key>]
+```
+
+| Option                   | Description                                                              |
+| ------------------------ | ------------------------------------------------------------------------ |
+| `--force`                | Overwrite files even if they have been modified                          |
+| `--script sh\|ps`        | Script type: `sh` (bash/zsh) or `ps` (PowerShell)                        |
+| `--integration-options`  | Options for the integration                                              |
+
+Reinstalls an installed integration with updated templates and commands (e.g., after upgrading Spec Kit). Defaults to the default integration; if a key is provided, it must be one of the installed integrations. Detects locally modified files and blocks the upgrade unless `--force` is used. Stale files from the previous install that are no longer needed are removed automatically. Shared templates stay aligned with the default integration even when upgrading a non-default integration.
+
+## Integration-Specific Options
+
+Some integrations accept additional options via `--integration-options`:
+
+| Integration | Option              | Description                                                    |
+| ----------- | ------------------- | -------------------------------------------------------------- |
+| `generic`   | `--commands-dir`    | Required. Directory for command files                          |
+| `kimi`      | `--migrate-legacy`  | Migrate legacy dotted skill directories to hyphenated format   |
+
+Example:
+
+```bash
+specify integration install generic --integration-options="--commands-dir .myagent/cmds"
+```
+
+## FAQ
+
+### Can I install multiple integrations in the same project?
+
+Yes, but it is intended for team portability rather than the default workflow. Multiple integrations are allowed automatically only when the installed integration and the new integration are declared multi-install safe by Spec Kit. For other combinations, pass `--force` to acknowledge that multiple agents may see unrelated agent-specific instructions or commands.
+
+Spec Kit tracks one default integration in `.specify/integration.json` with `default_integration`, all installed integrations with `installed_integrations`, per-integration runtime settings with `integration_settings`, and a dedicated `integration_state_schema` for future state migrations. The legacy `integration` field remains as an alias for the default integration.
+
+### Which integrations are multi-install safe?
+
+An integration is multi-install safe when it uses isolated agent directories, a dedicated context file that does not collide with another safe integration, stable command invocation settings, and a separate install manifest. Shared Spec Kit templates remain aligned to the single default integration.
+
+The currently declared multi-install safe integrations are:
+
+| Key | Isolation |
+| --- | --------- |
+| `auggie` | `.augment/commands`, `.augment/rules/specify-rules.md` |
+| `claude` | `.claude/skills`, `CLAUDE.md` |
+| `codebuddy` | `.codebuddy/commands`, `CODEBUDDY.md` |
+| `codex` | `.agents/skills`, `AGENTS.md` |
+| `cursor-agent` | `.cursor/skills`, `.cursor/rules/specify-rules.mdc` |
+| `gemini` | `.gemini/commands`, `GEMINI.md` |
+| `iflow` | `.iflow/commands`, `IFLOW.md` |
+| `junie` | `.junie/commands`, `.junie/AGENTS.md` |
+| `kilocode` | `.kilocode/workflows`, `.kilocode/rules/specify-rules.md` |
+| `kimi` | `.kimi/skills`, `KIMI.md` |
+| `qodercli` | `.qoder/commands`, `QODER.md` |
+| `qwen` | `.qwen/commands`, `QWEN.md` |
+| `roo` | `.roo/commands`, `.roo/rules/specify-rules.md` |
+| `shai` | `.shai/commands`, `SHAI.md` |
+| `tabnine` | `.tabnine/agent/commands`, `TABNINE.md` |
+| `trae` | `.trae/skills`, `.trae/rules/project_rules.md` |
+| `windsurf` | `.windsurf/workflows`, `.windsurf/rules/specify-rules.md` |
+
+Integrations that share a context file or command directory with another integration, require dynamic install paths such as `--commands-dir`, or merge shared tool settings are not declared safe by default. They can still be installed alongside another integration with `--force`.
+
+### What happens to my changes when I uninstall or switch?
+
+Files you've modified are preserved automatically. Only unmodified files (matching their original SHA-256 hash) are removed. Use `--force` to override this.
+
+### How do I know which key to use?
+
+Run `specify integration list` to see all available integrations with their keys, or check the [Supported AI Coding Agents](#supported-ai-coding-agents) table above.
+
+### Do I need the AI coding agent installed to use an integration?
+
+CLI-based integrations (like Claude Code, Gemini CLI) require the tool to be installed. IDE-based integrations (like Windsurf, Cursor) work through the IDE itself. Some agents like GitHub Copilot support both IDE and CLI usage. `specify integration list` shows which type each integration is.
+
+### When should I use `upgrade` vs `switch`?
+
+Use `upgrade` when you've upgraded Spec Kit and want to refresh an installed integration's managed files. Use `switch` when you want to replace the current default with another integration; if the target is already installed, `switch` behaves like `use`.

+# CLI Reference
+
+The Specify CLI (`specify`) manages the full lifecycle of Spec-Driven Development — from project initialization to workflow automation.
+
+## Core Commands
+
+The foundational commands for creating and managing Spec Kit projects. Initialize a new project with the necessary directory structure, templates, and scripts. Verify that your system has the required tools installed. Check version and system information.
+
+[Core Commands reference →](core.md)
+
+## Integrations
+
+Integrations connect Spec Kit to your AI coding agent. Each integration sets up the appropriate command files, context rules, and directory structures for a specific agent. Only one integration is active per project at a time, and you can switch between them at any point.
+
+[Integrations reference →](integrations.md)
+
+## Extensions
+
+Extensions add new capabilities to Spec Kit — domain-specific commands, external tool integrations, quality gates, and more. They are discovered through catalogs and can be installed, updated, enabled, disabled, or removed independently. Multiple extensions can coexist in a single project.
+
+[Extensions reference →](extensions.md)
+
+## Presets
+
+Presets customize how Spec Kit works — overriding command files, template files, and script files without changing any tooling. They let you enforce organizational standards, adapt the workflow to your methodology, or localize the entire experience. Multiple presets can be stacked with priority ordering to layer customizations.
+
+[Presets reference →](presets.md)
+
+## Workflows
+
+Workflows automate multi-step Spec-Driven Development processes into repeatable sequences. They chain commands, prompts, shell steps, and human checkpoints together, with support for conditional logic, loops, fan-out/fan-in, and the ability to pause and resume from the exact point of interruption.

+# Presets
+
+Presets customize how Spec Kit works — overriding templates, commands, and terminology without changing any tooling. They let you enforce organizational standards, adapt the workflow to your methodology, or localize the entire experience. Multiple presets can be stacked with priority ordering.
+
+## Search Available Presets
+
+```bash
+specify preset search [query]
+```
+
+| Option     | Description          |
+| ---------- | -------------------- |
+| `--tag`    | Filter by tag        |
+| `--author` | Filter by author     |
+
+Searches all active catalogs for presets matching the query. Without a query, lists all available presets.
+
+## Install a Preset
+
+```bash
+specify preset add [<preset_id>]
+```
+
+| Option           | Description                                              |
+| ---------------- | -------------------------------------------------------- |
+| `--dev <path>`   | Install from a local directory (for development)         |
+| `--from <url>`   | Install from a custom URL instead of the catalog         |
+| `--priority <N>` | Resolution priority (default: 10; lower = higher precedence) |
+
+Installs a preset from the catalog, a URL, or a local directory. Preset commands are automatically registered with the currently installed AI coding agent integration.
+
+> **Note:** All preset commands require a project already initialized with `specify init`.
+
+## Remove a Preset
+
+```bash
+specify preset remove <preset_id>
+```
+
+Removes an installed preset and cleans up its registered commands.
+
+## List Installed Presets
+
+```bash
+specify preset list
+```
+
+Lists installed presets with their versions, descriptions, template counts, and current status.
+
+## Preset Info
+
+```bash
+specify preset info <preset_id>
+```
+
+Shows detailed information about an installed or available preset, including its templates, metadata, and tags.
+
+## Resolve a File
+
+```bash
+specify preset resolve <name>
+```
+
+Shows which file will be used for a given name by tracing the full resolution stack. Useful for debugging when multiple presets provide the same file.
+
+## Enable / Disable a Preset
+
+```bash
+specify preset enable <preset_id>
+specify preset disable <preset_id>
+```
+
+Disable a preset without removing it. Disabled presets are skipped during file resolution but their commands remain registered. Re-enable with `enable`.
+
+## Set Preset Priority
+
+```bash
+specify preset set-priority <preset_id> <priority>
+```
+
+Changes the resolution priority of an installed preset. Lower numbers take precedence. When multiple presets provide the same file, the one with the lowest priority number wins.
+
+## Catalog Management
+
+Preset catalogs control where `search` and `add` look for presets. Catalogs are checked in priority order (lower number = higher precedence).
+
+### List Catalogs
+
+```bash
+specify preset catalog list
+```
+
+Shows all active catalogs with their priorities and install permissions.
+
+### Add a Catalog
+
+```bash
+specify preset catalog add <url>
+```
+
+| Option                                       | Description                                        |
+| -------------------------------------------- | -------------------------------------------------- |
+| `--name <name>`                              | Required. Unique name for the catalog              |
+| `--priority <N>`                             | Priority (default: 10; lower = higher precedence)  |
+| `--install-allowed / --no-install-allowed`   | Whether presets can be installed from this catalog (default: discovery only) |
+| `--description <text>`                       | Optional description                               |
+
+Adds a catalog to the project's `.specify/preset-catalogs.yml`.
+
+### Remove a Catalog
+
+```bash
+specify preset catalog remove <name>
+```
+
+Removes a catalog from the project configuration.
+
+### Catalog Resolution Order
+
+Catalogs are resolved in this order (first match wins):
+
+1. **Environment variable** — `SPECKIT_PRESET_CATALOG_URL` overrides all catalogs
+2. **Project config** — `.specify/preset-catalogs.yml`
+3. **User config** — `~/.specify/preset-catalogs.yml`
+4. **Built-in defaults** — official catalog + community catalog
+
+Example `.specify/preset-catalogs.yml`:
+
+```yaml
+catalogs:
+  - name: "my-org-presets"
+    url: "https://example.com/preset-catalog.json"
+    priority: 5
+    install_allowed: true
+    description: "Our approved presets"
+```
+
+## File Resolution
+
+Presets can provide command files, template files (like `plan-template.md`), and script files. These are resolved at runtime using a **replace** strategy — the first match in the priority stack wins and is used entirely. Each file is looked up independently, so different files can come from different layers.
+
+> **Note:** Additional composition strategies (`append`, `prepend`, `wrap`) are planned for a future release.
+
+The resolution stack, from highest to lowest precedence:
+
+1. **Project-local overrides** — `.specify/templates/overrides/`
+2. **Installed presets** — sorted by priority (lower = checked first)
+3. **Installed extensions** — sorted by priority
+4. **Spec Kit core** — `.specify/templates/`
+
+Commands are registered at install time (not resolved through the stack at runtime).
+
+### Resolution Stack
+
+```mermaid
+flowchart TB
+    subgraph stack [" "]
+        direction TB
+        A["⬆ Highest precedence<br/><br/>1. Project-local overrides<br/>.specify/templates/overrides/"]
+        B["2. Presets — by priority<br/>.specify/presets/‹id›/"]
+        C["3. Extensions — by priority<br/>.specify/extensions/‹id›/"]
+        D["4. Spec Kit core<br/>.specify/templates/<br/><br/>⬇ Lowest precedence"]
+    end
+
+    A --> B --> C --> D
+
+    style A fill:#4a9,color:#fff
+    style B fill:#49a,color:#fff
+    style C fill:#a94,color:#fff
+    style D fill:#999,color:#fff
+```
+
+Within each layer, files are organized by type:
+
+| Type      | Subdirectory   | Override path                              |
+| --------- | -------------- | ------------------------------------------ |
+| Templates | `templates/`   | `.specify/templates/overrides/`            |
+| Commands  | `commands/`    | `.specify/templates/overrides/`            |
+| Scripts   | `scripts/`     | `.specify/templates/overrides/scripts/`    |
+
+### Resolution in Action
+
+```mermaid
+flowchart TB
+    A["File requested:<br/>plan-template.md"] --> B{"Project-local override?"}
+    B -- Found --> Z["✓ Use this file"]
+    B -- Not found --> C{"Preset: compliance<br/>(priority 5)"}
+    C -- Found --> Z
+    C -- Not found --> D{"Preset: team-workflow<br/>(priority 10)"}
+    D -- Found --> Z
+    D -- Not found --> E{"Extension files?"}
+    E -- Found --> Z
+    E -- Not found --> F["Spec Kit core"]
+    F --> Z
+```
+
+### Example
+
+```bash
+specify preset add compliance --priority 5
+specify preset add team-workflow --priority 10
+```
+
+For any file that both provide, `compliance` wins (priority 5 < 10). For files only one provides, that one is used. For files neither provides, the core default is used.
+
+## FAQ
+
+### Can I use multiple presets at the same time?
+
+Yes. Presets stack by priority — each file is resolved independently from the highest-priority source that provides it. Use `specify preset set-priority` to control the order.
+
+### How do I see which file is actually being used?
+
+Run `specify preset resolve <name>` to trace the resolution stack and see which file wins.
+
+### What's the difference between disabling and removing a preset?
+
+**Disabling** (`specify preset disable`) keeps the preset installed but excludes its files from the resolution stack. Commands the preset registered remain available in your AI coding agent. This is useful for temporarily testing behavior without a preset, or comparing output with and without it. Re-enable anytime with `specify preset enable`.
+
+**Removing** (`specify preset remove`) fully uninstalls the preset — deletes its files, unregisters its commands from your AI coding agent, and removes it from the registry.
+
+### Who maintains presets?
+
+Most presets are independently created and maintained by their respective authors. The Spec Kit maintainers do not review, audit, endorse, or support preset code. Review a preset's source code before installing and use at your own discretion. For issues with a specific preset, contact its author or file an issue on the preset's repository.

+# Workflows
+
+Workflows automate multi-step Spec-Driven Development processes — chaining commands, prompts, shell steps, and human checkpoints into repeatable sequences. They support conditional logic, loops, fan-out/fan-in, and can be paused and resumed from the exact point of interruption.
+
+## Run a Workflow
+
+```bash
+specify workflow run <source>
+```
+
+| Option              | Description                                              |
+| ------------------- | -------------------------------------------------------- |
+| `-i` / `--input`    | Pass input values as `key=value` (repeatable)            |
+
+Runs a workflow from a catalog ID, URL, or local file path. Inputs declared by the workflow can be provided via `--input` or will be prompted interactively.
+
+Example:
+
+```bash
+specify workflow run speckit -i spec="Build a kanban board with drag-and-drop task management" -i scope=full
+```
+
+> **Note:** All workflow commands require a project already initialized with `specify init`.
+
+## Resume a Workflow
+
+```bash
+specify workflow resume <run_id>
+```
+
+Resumes a paused or failed workflow run from the exact step where it stopped. Useful after responding to a gate step or fixing an issue that caused a failure.
+
+## Workflow Status
+
+```bash
+specify workflow status [<run_id>]
+```
+
+Shows the status of a specific run, or lists all runs if no ID is given. Run states: `created`, `running`, `completed`, `paused`, `failed`, `aborted`.
+
+## List Installed Workflows
+
+```bash
+specify workflow list
+```
+
+Lists workflows installed in the current project.
+
+## Install a Workflow
+
+```bash
+specify workflow add <source>
+```
+
+Installs a workflow from the catalog, a URL (HTTPS required), or a local file path.
+
+## Remove a Workflow
+
+```bash
+specify workflow remove <workflow_id>
+```
+
+Removes an installed workflow from the project.
+
+## Search Available Workflows
+
+```bash
+specify workflow search [query]
+```
+
+| Option  | Description     |
+| ------- | --------------- |
+| `--tag` | Filter by tag   |
+
+Searches all active catalogs for workflows matching the query.
+
+## Workflow Info
+
+```bash
+specify workflow info <workflow_id>
+```
+
+Shows detailed information about a workflow, including its steps, inputs, and requirements.
+
+## Catalog Management
+
+Workflow catalogs control where `search` and `add` look for workflows. Catalogs are checked in priority order.
+
+### List Catalogs
+
+```bash
+specify workflow catalog list
+```
+
+Shows all active catalog sources.
+
+### Add a Catalog
+
+```bash
+specify workflow catalog add <url>
+```
+
+| Option          | Description                      |
+| --------------- | -------------------------------- |
+| `--name <name>` | Optional name for the catalog    |
+
+Adds a custom catalog URL to the project's `.specify/workflow-catalogs.yml`.
+
+### Remove a Catalog
+
+```bash
+specify workflow catalog remove <index>
+```
+
+Removes a catalog by its index in the catalog list.
+
+### Catalog Resolution Order
+
+Catalogs are resolved in this order (first match wins):
+
+1. **Environment variable** — `SPECKIT_WORKFLOW_CATALOG_URL` overrides all catalogs
+2. **Project config** — `.specify/workflow-catalogs.yml`
+3. **User config** — `~/.specify/workflow-catalogs.yml`
+4. **Built-in defaults** — official catalog + community catalog
+
+## Workflow Definition
+
+Workflows are defined in YAML files. Here is the built-in **Full SDD Cycle** workflow that ships with Spec Kit:
+
+```yaml
+schema_version: "1.0"
+workflow:
+  id: "speckit"
+  name: "Full SDD Cycle"
+  version: "1.0.0"
+  author: "GitHub"
+  description: "Runs specify → plan → tasks → implement with review gates"
+
+requires:
+  speckit_version: ">=0.7.2"
+  integrations:
+    any: ["copilot", "claude", "gemini"]
+
+inputs:
+  spec:
+    type: string
+    required: true
+    prompt: "Describe what you want to build"
+  integration:
+    type: string
+    default: "copilot"
+    prompt: "Integration to use (e.g. claude, copilot, gemini)"
+  scope:
+    type: string
+    default: "full"
+    enum: ["full", "backend-only", "frontend-only"]
+
+steps:
+  - id: specify
+    command: speckit.specify
+    integration: "{{ inputs.integration }}"
+    input:
+      args: "{{ inputs.spec }}"
+
+  - id: review-spec
+    type: gate
+    message: "Review the generated spec before planning."
+    options: [approve, reject]
+    on_reject: abort
+
+  - id: plan
+    command: speckit.plan
+    integration: "{{ inputs.integration }}"
+    input:
+      args: "{{ inputs.spec }}"
+
+  - id: review-plan
+    type: gate
+    message: "Review the plan before generating tasks."
+    options: [approve, reject]
+    on_reject: abort
+
+  - id: tasks
+    command: speckit.tasks
+    integration: "{{ inputs.integration }}"
+    input:
+      args: "{{ inputs.spec }}"
+
+  - id: implement
+    command: speckit.implement
+    integration: "{{ inputs.integration }}"
+    input:
+      args: "{{ inputs.spec }}"
+```
+
+This produces the following execution flow:
+
+```mermaid
+flowchart TB
+    A["specify<br/>(command)"] --> B{"review-spec<br/>(gate)"}
+    B -- approve --> C["plan<br/>(command)"]

+    C --> D{"review-plan<br/>(gate)"}
+    D -- approve --> E["tasks<br/>(command)"]
+    D -- reject --> X2["⏹ Abort"]

+    style F fill:#49a,color:#fff
+    style X1 fill:#999,color:#fff
+    style X2 fill:#999,color:#fff
+```
+
+Run it with:
+
+```bash
+specify workflow run speckit -i spec="Build a kanban board with drag-and-drop task management"
+```
+
+## Step Types
+
+| Type         | Purpose                                          |
+| ------------ | ------------------------------------------------ |
+| `command`    | Invoke a Spec Kit command (e.g., `speckit.plan`) |
+| `prompt`     | Send an arbitrary prompt to the AI coding agent  |
+| `shell`      | Execute a shell command and capture output       |
+| `gate`       | Pause for human approval before continuing       |
+| `if`         | Conditional branching (then/else)                |
+| `switch`     | Multi-branch dispatch on an expression           |
+| `while`      | Loop while a condition is true                   |
+| `do-while`   | Execute at least once, then loop on condition    |
+| `fan-out`    | Dispatch a step for each item in a list          |
+| `fan-in`     | Aggregate results from a fan-out step            |
+
+## Expressions
+
+Steps can reference inputs and previous step outputs using `{{ expression }}` syntax:
+
+| Namespace                      | Description                          |
+| ------------------------------ | ------------------------------------ |
+| `inputs.spec`                  | Workflow input values                |
+| `steps.specify.output.file`    | Output from a previous step          |
+| `item`                         | Current item in a fan-out iteration  |
+
+Available filters: `default`, `join`, `contains`, `map`.
+
+Example:
+
+```yaml
+condition: "{{ steps.test.output.exit_code == 0 }}"
+args: "{{ inputs.spec }}"
+message: "{{ status | default('pending') }}"
+```
+
+## Input Types
+
+| Type      | Coercion                                          |
+| --------- | ------------------------------------------------- |
+| `string`  | Pass-through                                      |
+| `number`  | `"42"` → `42`, `"3.14"` → `3.14`                 |
+| `boolean` | `"true"` / `"1"` / `"yes"` → `True`              |
+
+## State and Resume
+
+Each workflow run persists its state at `.specify/workflows/runs/<run_id>/`:
+
+- `state.json` — current run state and step progress
+- `inputs.json` — resolved input values
+- `log.jsonl` — step-by-step execution log
+
+This enables `specify workflow resume` to continue from the exact step where a run was paused (e.g., at a gate) or failed.
+
+## FAQ
+
+### What happens when a workflow hits a gate step?
+
+The workflow pauses and waits for human input. Run `specify workflow resume <run_id>` after reviewing to continue.
+
+### Can I run the same workflow multiple times?
+
+Yes. Each run gets a unique ID and its own state directory. Use `specify workflow status` to see all runs.
+
+### Who maintains workflows?
+
+Most workflows are independently created and maintained by their respective authors. The Spec Kit maintainers do not review, audit, endorse, or support workflow code. Review a workflow's source before installing and use at your own discretion.

+# 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 |
+| **CLI Tool Only (pipx)** | `pipx install --force git+https://github.com/github/spec-kit.git@vX.Y.Z` | Reinstall/upgrade a pipx-installed CLI to a specific release |
+| **Project Files** | `specify init --here --force --integration <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 --integration copilot
+```
+
+### If you installed with `pipx`
+
+Upgrade to a specific release:
+
+```bash
+pipx install --force git+https://github.com/github/spec-kit.git@vX.Y.Z
+```
+
+### 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/`) — **only with `--force`**; without it, only missing files are added
+- ✅ **Template files** (`.specify/templates/`) — **only with `--force`**; without it, only missing files are added
+- ✅ **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 --integration <your-agent>
+```
+
+Replace `<your-agent>` with your AI coding agent. Refer to this list of [Supported AI Coding Agent Integrations](reference/integrations.md)
+
+**Example:**
+
+```bash
+specify init --here --force --integration 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. It also **overwrites shared infrastructure files** (`.specify/scripts/` and `.specify/templates/`) with the latest versions from the installed Spec Kit release.
+
+Without `--force`, shared infrastructure files that already exist are skipped — the CLI will print a warning listing the skipped files so you know which ones were not updated.
+
+**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 --integration 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 script or template modifications
+
+If you customized files in `.specify/scripts/` or `.specify/templates/`, the `--force` flag will overwrite them. Back them up first:
+
+```bash
+# Back up custom templates and scripts
+cp -r .specify/templates .specify/templates-backup
+cp -r .specify/scripts .specify/scripts-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 --integration 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 --integration 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 --integration 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 --integration copilot --no-git
+```
+
+**During upgrade:**
+
+```bash
+specify init --here --force --integration 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 --integration 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 coding agent 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

+```
+
+### Special Variables
+
+- `$ARGUMENTS` - Placeholder for user-provided arguments
+- Extension context automatically injected:
+
+  ```markdown
+  <!-- Extension: {extension-id} -->
+  <!-- Config: .specify/extensions/{extension-id}/ -->
+  ```
+
+---
+
+## Configuration Schema
+
+### Extension Config File
+
+**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
+```
+
+### Hook Events
+
+Standard events (defined by core):
+
+- `before_specify` - Before specification generation
+- `after_specify` - After specification generation
+- `before_plan` - Before implementation planning
+- `after_plan` - After implementation planning
+- `before_tasks` - Before task generation
+- `after_tasks` - After task generation
+- `before_implement` - Before implementation
+- `after_implement` - After implementation
+- `before_analyze` - Before cross-artifact analysis
+- `after_analyze` - After cross-artifact analysis
+- `before_checklist` - Before checklist generation
+- `after_checklist` - After checklist generation
+- `before_clarify` - Before spec clarification
+- `after_clarify` - After spec clarification
+- `before_constitution` - Before constitution update
+- `after_constitution` - After constitution update
+- `before_taskstoissues` - Before tasks-to-issues conversion
+- `after_taskstoissues` - After tasks-to-issues conversion
+
+### Hook Configuration
+
+**In `.specify/extensions.yml`**:
+
+```yaml
+hooks:
+  after_tasks:
+    - extension: jira
+      command: speckit.jira.specstoissues
+      enabled: true
+      optional: true
+      prompt: "Create Jira issues from tasks?"
+      description: "..."
+      condition: null
+```
+
+### Hook Message Format
+
+```markdown
+## Extension Hooks
+
+**Optional Hook**: {extension}
+Command: `/{command}`
+Description: {description}
+
+Prompt: {prompt}
+To execute: `/{command}`
+```
+
+Or for mandatory hooks:

+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`
+
+---
+
+## Testing Extensions
+
+### Manual Testing
+
+1. **Create test extension**
+2. **Install locally**:
+
+   ```bash
+   specify extension add --dev /path/to/extension
+   ```
+
+3. **Verify installation**:
+
+   ```bash
+   specify extension list
+   ```
+
+4. **Test commands** with your AI agent
+5. **Check command registration**:
+
+   ```bash
+   ls .claude/commands/speckit.my-ext.*
+   ```
+
+6. **Remove extension**:
+
+   ```bash
+   specify extension remove my-ext
+   ```
+
+### Automated Testing
+
+Create tests for your extension:
+
+```python
+# tests/test_my_extension.py
+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:
+        cmd_file = Path(cmd["file"])
+        assert cmd_file.exists(), f"Command file not found: {cmd_file}"
+```
+
+---
+
+## Distribution
+
+### Option 1: GitHub Repository
+
+1. **Create repository**: `spec-kit-my-ext`
+2. **Add files**:
+
+   ```text
+   spec-kit-my-ext/
+   ├── extension.yml
+   ├── commands/
+   ├── scripts/
+   ├── docs/
+   ├── README.md
+   ├── LICENSE
+   └── CHANGELOG.md
+   ```
+
+3. **Create release**: Tag with version (e.g., `v1.0.0`)
+4. **Install from repo**:
+
+   ```bash
+   git clone https://github.com/you/spec-kit-my-ext
+   specify extension add --dev spec-kit-my-ext/
+   ```
+
+### Option 2: ZIP Archive (Future)
+
+Create ZIP archive and host on GitHub Releases:
+
+```bash
+zip -r spec-kit-my-ext-1.0.0.zip extension.yml commands/ scripts/ docs/
+```
+
+Users install with:
+
+```bash
+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. **Create a GitHub release** for your extension
+2. **File an issue** using the [Extension Submission](https://github.com/github/spec-kit/issues/new?template=extension_submission.yml) template
+3. **After review**, a maintainer updates the catalog and 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 --from git+https://github.com/github/spec-kit.git`. The bare `specify-cli` package on PyPI is a different, unrelated project — installing it without `--from git+...` will give you a stub CLI that does not include `extension`, `preset`, or other spec-kit commands.
+
+**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
+

+# Extension Publishing Guide
+
+This guide explains how to publish your extension to the Spec Kit extension catalog, making it discoverable by `specify extension search`.
+

+2. [Prepare Your Extension](#prepare-your-extension)
+3. [Submit to Catalog](#submit-to-catalog)
+4. [Release Workflow](#release-workflow)
+5. [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 are listed in `extensions/catalog.community.json`. Users browse this catalog and copy extensions they trust into their own `catalog.json`.
+
+### How to Submit
+
+To submit your extension to the community catalog, file a new issue using the **[Extension Submission](https://github.com/github/spec-kit/issues/new?template=extension_submission.yml)** template. The template collects all required metadata, including:
+
+- Extension ID, name, and version
+- Description, author, and license
+- Repository, download URL, and documentation links
+- Required Spec Kit version and any tool dependencies
+- Number of commands and hooks
+- Tags and key features
+- Testing confirmation
+
+> [!IMPORTANT]
+> Do **not** open a pull request directly to edit `extensions/catalog.community.json`. All community extension submissions must go through the issue template so a maintainer can review the entry and update the catalog.
+
+### What Happens After You Submit
+
+1. Your issue is automatically labeled and assigned to a maintainer for review
+2. A maintainer verifies that the catalog entry is complete and correctly formatted
+3. Once approved, the maintainer adds your extension to `extensions/catalog.community.json` and the Community Extensions table in the README
+4. Your extension becomes discoverable via `specify extension search`
+
+### What Maintainers Check
+
+- The catalog entry fields are complete and correctly formatted
+- The download URL is accessible
+- The repository exists and contains an `extension.yml` manifest
+
+> [!NOTE]
+> Maintainers do **not** review, audit, or test the extension code itself.
+
+### Typical Review Timeline
+
+- **Review**: 3-7 business days
+
+### Updating an Existing Extension
+
+To update an extension that is already in the catalog (e.g., for a new version), file a new **[Extension Submission](https://github.com/github/spec-kit/issues/new?template=extension_submission.yml)** issue with the updated version, download URL, and any other changed fields. Mention in the issue that this is an update to an existing entry.
+

+
+## 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. **File an update submission** using the [Extension Submission](https://github.com/github/spec-kit/issues/new?template=extension_submission.yml) template with the new version and download URL. Mention in the issue that this is an update to an existing entry.
+
+---
+
+## 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 review take?
+
+A: Typically 3-7 business days. Updates to existing 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, file a new [Extension Submission](https://github.com/github/spec-kit/issues/new?template=extension_submission.yml) issue with the updated version and download URL. Mention that it is an update to an existing entry.
+
+### Q: Do I need to be verified to be in the catalog?
+
+A: No. All community extensions are listed in the catalog once their submission is reviewed and accepted.
+
+### 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. Maintainers only verify that catalog entries are complete and correctly formatted — 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 [issue template](https://github.com/github/spec-kit/issues/new?template=extension_submission.yml)
+
+**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. Maintainers only verify that catalog entries are complete and correctly formatted — 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)
+2. **Create a GitHub release** for your extension
+3. **File an issue** using the [Extension Submission](https://github.com/github/spec-kit/issues/new?template=extension_submission.yml) template with all required metadata
+4. **Wait for review** — a maintainer will review the submission, update the catalog, and close the issue
+
+See the [Extension Publishing Guide](EXTENSION-PUBLISHING-GUIDE.md) for detailed step-by-step instructions.
+
+### Submission Checklist
+
+Before submitting, ensure:
+
+- ✅ Valid `extension.yml` manifest
+- ✅ Complete README with installation and usage instructions
+- ✅ LICENSE file included
+- ✅ GitHub release created with semantic version (e.g., v1.0.0)
+- ✅ Extension tested on a real project
+- ✅ All commands working as documented
+
+## Installing Extensions
+Once extensions are available (either in your catalog or via direct URL), install them:
+
+```bash
+# From your curated catalog (by name)
+specify extension search                  # See what's in your catalog
+specify extension add <extension-name>    # Install by name
+
+# Direct from URL (bypasses catalog)
+specify extension add <extension-name> --from https://github.com/<org>/<repo>/archive/refs/tags/<version>.zip
+
+# List installed extensions
+specify extension list
+```
+
+For more information, see the [Extension User Guide](EXTENSION-USER-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)
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `speckit.git.initialize` | Initialize a Git repository with a configurable commit message |
+| `speckit.git.feature` | Create a feature branch with sequential or timestamp numbering |
+| `speckit.git.validate` | Validate current branch follows feature branch naming conventions |
+| `speckit.git.remote` | Detect Git remote URL for GitHub integration |
+| `speckit.git.commit` | Auto-commit changes (configurable per-command enable/disable and 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_COMMAND_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`

+
+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

+- 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:

+```
+
+## 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]

+

+3. Prerequisite 3 (e.g., "Valid API credentials")
+
+## User Input
+
+$ARGUMENTS
+
+## Steps
+
+### Step 1: Load Configuration
+
+<!-- CUSTOMIZE: Replace with your actual steps -->
+
+Load extension configuration from the project:
+
+``bash
+config_file=".specify/extensions/my-extension/my-extension-config.yml"
+
+if [ ! -f "$config_file" ]; then
+  echo "❌ Error: Configuration not found at $config_file"
+  echo "Run 'specify extension add my-extension' to install and configure"
+  exit 1
+fi
+
+# Read configuration values
+
+setting_value=$(yq eval '.settings.key' "$config_file")
+
+# Apply environment variable overrides
+
+setting_value="${SPECKIT_MY_EXTENSION_KEY:-$setting_value}"
+
+# Validate configuration
+
+if [ -z "$setting_value" ]; then
+  echo "❌ Error: Configuration value not set"
+  echo "Edit $config_file and set 'settings.key'"
+  exit 1
+fi
+
+echo "📋 Configuration loaded: $setting_value"
+``
+
+### Step 2: Perform Main Action
+
+<!-- CUSTOMIZE: Replace with your command logic -->
+
+Describe what this step does:
+
+``markdown
+Use MCP tools to perform the main action:
+
+- Tool: example-mcp-server example_tool
+- Parameters: { "key": "$setting_value" }
+
+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 ""
+echo "Results:"
+echo "  • Item 1: Value"
+echo "  • Item 2: Value"
+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:

+# Contributing to the Integration Catalog
+
+This guide covers adding integrations to both the **built-in** and **community** catalogs.
+
+## Adding a Built-In Integration
+
+Built-in integrations are maintained by the Spec Kit core team and ship with the CLI.
+
+### Checklist
+
+1. **Create the integration subpackage** under `src/specify_cli/integrations/<package_dir>/`
+   — `<package_dir>` matches the integration key when it contains no hyphens (e.g., `gemini`), or replaces hyphens with underscores when it does (e.g., key `cursor-agent` → directory `cursor_agent/`, key `kiro-cli` → directory `kiro_cli/`). Python package names cannot use hyphens.
+2. **Implement the integration class** extending `MarkdownIntegration`, `TomlIntegration`, or `SkillsIntegration`
+3. **Register the integration** in `src/specify_cli/integrations/__init__.py`
+4. **Add tests** under `tests/integrations/test_integration_<package_dir>.py`
+5. **Add a catalog entry** in `integrations/catalog.json`
+6. **Update documentation** in `AGENTS.md` and `README.md`
+
+### Catalog Entry Format
+
+Add your integration under the top-level `integrations` key in `integrations/catalog.json`:
+
+```json
+{
+  "schema_version": "1.0",
+  "integrations": {
+    "my-agent": {
+      "id": "my-agent",
+      "name": "My Agent",
+      "version": "1.0.0",
+      "description": "Integration for My Agent",
+      "author": "spec-kit-core",
+      "repository": "https://github.com/github/spec-kit",
+      "tags": ["cli"]
+    }
+  }
+}
+```
+
+## Adding a Community Integration
+
+Community integrations are contributed by external developers and listed in `integrations/catalog.community.json` for discovery.
+
+### Prerequisites
+
+1. **Working integration** — tested with `specify integration install`
+2. **Public repository** — hosted on GitHub or similar
+3. **`integration.yml` descriptor** — valid descriptor file (see below)
+4. **Documentation** — README with usage instructions
+5. **License** — open source license file
+
+### `integration.yml` Descriptor
+
+Every community integration must include an `integration.yml`:
+
+```yaml
+schema_version: "1.0"
+integration:
+  id: "my-agent"
+  name: "My Agent"
+  version: "1.0.0"
+  description: "Integration for My Agent"
+  author: "your-name"
+  repository: "https://github.com/your-name/speckit-my-agent"
+  license: "MIT"
+requires:
+  speckit_version: ">=0.6.0"
+  tools:
+    - name: "my-agent"
+      version: ">=1.0.0"
+      required: true
+provides:
+  commands:
+    - name: "speckit.specify"
+      file: "templates/speckit.specify.md"
+  scripts:
+    - update-context.sh
+```
+
+### Descriptor Validation Rules
+
+| Field | Rule |
+|-------|------|
+| `schema_version` | Must be `"1.0"` |
+| `integration.id` | Lowercase alphanumeric + hyphens (`^[a-z0-9-]+$`) |
+| `integration.version` | Valid PEP 440 version (parsed with `packaging.version.Version()`) |
+| `requires.speckit_version` | Required field; specify a version constraint such as `>=0.6.0` (current validation checks presence only) |
+| `provides` | Must include at least one command or script |
+| `provides.commands[].name` | String identifier |
+| `provides.commands[].file` | Relative path to template file |
+
+### Submitting to the Community Catalog
+
+1. **Fork** the [spec-kit repository](https://github.com/github/spec-kit)
+2. **Add your entry** under the `integrations` key in `integrations/catalog.community.json`:
+
+```json
+{
+  "schema_version": "1.0",
+  "integrations": {
+    "my-agent": {
+      "id": "my-agent",
+      "name": "My Agent",
+      "version": "1.0.0",
+      "description": "Integration for My Agent",
+      "author": "your-name",
+      "repository": "https://github.com/your-name/speckit-my-agent",
+      "tags": ["cli"]
+    }
+  }
+}
+```
+
+3. **Open a pull request** with:
+   - Your catalog entry
+   - Link to your integration repository
+   - Confirmation that `integration.yml` is valid
+
+### Version Updates
+
+To update your integration version in the catalog:
+
+1. Release a new version of your integration
+2. Open a PR updating the `version` field in `catalog.community.json`
+3. Ensure backward compatibility or document breaking changes
+
+## Upgrade Workflow
+
+The `specify integration upgrade` command supports diff-aware upgrades:
+
+1. **Hash comparison** — the manifest records SHA-256 hashes of all installed files
+2. **Modified file detection** — files changed since installation are flagged
+3. **Safe default** — the upgrade blocks if any installed files were modified since installation
+4. **Forced reinstall** — passing `--force` overwrites modified files with the latest version
+
+```bash
+# Upgrade current integration (blocks if files are modified)
+specify integration upgrade
+
+# Force upgrade (overwrites modified files)
+specify integration upgrade --force
+```

+# Spec Kit Integration Catalog
+
+The integration catalog enables discovery, versioning, and distribution of AI agent integrations for Spec Kit.
+
+## Catalog Files
+
+### Built-In Catalog (`catalog.json`)
+
+Contains integrations that ship with Spec Kit. These are maintained by the core team and always installable.
+
+### Community Catalog (`catalog.community.json`)
+
+Community-contributed integrations. Listed for discovery only — users install from the source repositories.
+
+## Catalog Configuration
+
+The catalog stack is resolved in this order (first match wins):
+
+1. **Environment variable** — `SPECKIT_INTEGRATION_CATALOG_URL` overrides all catalogs with a single URL
+2. **Project config** — `.specify/integration-catalogs.yml` in the project root
+3. **User config** — `~/.specify/integration-catalogs.yml` in the user home directory
+4. **Built-in defaults** — `catalog.json` + `catalog.community.json`
+
+Example `integration-catalogs.yml`:
+
+```yaml
+catalogs:
+  - url: "https://example.com/my-catalog.json"
+    name: "my-catalog"
+    priority: 1
+    install_allowed: true
+```
+
+## CLI Commands
+
+```bash
+# List built-in integrations (default)
+specify integration list
+
+# Browse full catalog (built-in + community)
+specify integration list --catalog
+
+# Install an integration
+specify integration install copilot
+
+# Upgrade the current integration (diff-aware)
+specify integration upgrade
+
+# Upgrade with force (overwrite modified files)
+specify integration upgrade --force
+```
+
+## Integration Descriptor (`integration.yml`)
+
+Each integration can include an `integration.yml` descriptor that documents its metadata, requirements, and provided commands/scripts:
+
+```yaml
+schema_version: "1.0"
+integration:
+  id: "my-agent"
+  name: "My Agent"
+  version: "1.0.0"
+  description: "Integration for My Agent"
+  author: "my-org"
+  repository: "https://github.com/my-org/speckit-my-agent"
+  license: "MIT"
+requires:
+  speckit_version: ">=0.6.0"
+  tools:
+    - name: "my-agent"
+      version: ">=1.0.0"
+      required: true
+provides:
+  commands:
+    - name: "speckit.specify"
+      file: "templates/speckit.specify.md"
+    - name: "speckit.plan"
+      file: "templates/speckit.plan.md"
+  scripts:
+    - update-context.sh
+    - update-context.ps1
+```
+
+## Catalog Schema
+
+Both catalog files follow the same JSON schema:
+
+```json
+{
+  "schema_version": "1.0",
+  "updated_at": "2026-04-08T00:00:00Z",

+      "repository": "https://github.com/my-org/speckit-my-agent",
+      "tags": ["cli"]
+    }
+  }
+}
+```
+
