chore: bump version to 0.7.2

docs: add core commands reference and simplify README CLI section (#2245 )
* docs: add core commands reference and simplify README CLI section - New docs/reference/core.md: reference for init (active options only, copilot as main example), check, and version commands - docs/toc.yml: add Core Commands under Reference - README.md: replace verbose CLI Reference section (init options table, 30+ per-agent examples, deprecated flags, env vars) with links to reference docs; use copilot as main example throughout * docs: add CLI reference overview page - New docs/reference/overview.md: explains each CLI surface area (core, integrations, extensions, presets, workflows) with key commands and links to detailed reference pages - docs/toc.yml: add Overview as first item under Reference - README.md: simplify CLI Reference to single link to overview page * docs: remove command references from overview, keep paragraphs only

-## Adding New Agent Support
+## Integration Architecture

-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.
+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()`.

-### 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:
+The registry is the **single source of truth for Python integration metadata**. Supported agents, their directories, formats, and capabilities are derived from the integration classes for the Python integration layer. However, context-update behavior still requires explicit cases in the shared dispatcher scripts (`scripts/bash/update-agent-context.sh` and `scripts/powershell/update-agent-context.ps1`), which currently maintain their own supported-agent lists and agent-key→context-file mappings until they are migrated to registry-based dispatch.

- **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

-### Step-by-Step Integration Guide
+| 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 |

-Follow these steps to add a new agent (using a hypothetical new agent as an example):
+Most agents only need `MarkdownIntegration` — a minimal subclass with zero method overrides.

-#### 1. Add to AGENT_CONFIG
+### 2. Create the subpackage

-**IMPORTANT**: Use the actual CLI tool name as the key, not a shortened version.
+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.

-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
-        "commands_subdir": "commands",  # Subdirectory name for command files (default: "commands")
-        "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."""
+
+from ..base import MarkdownIntegration
+
+
+class WindsurfIntegration(MarkdownIntegration):
+    key = "windsurf"
+    config = {
+        "name": "Windsurf",
+        "folder": ".windsurf/",
+        "commands_subdir": "workflows",
+        "install_url": None,
+        "requires_cli": False,
+    }
+    registrar_config = {
+        "dir": ".windsurf/workflows",
+        "format": "markdown",
+        "args": "$ARGUMENTS",
+        "extension": ".md",
+    }
+    context_file = ".windsurf/rules/specify-rules.md"
 ```

-**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`
-
-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)
- `commands_subdir`: Subdirectory name within the agent folder where command/prompt files are stored (default: `"commands"`)
-  - Most agents use `"commands"` (e.g., `.claude/commands/`)
-  - Some agents use alternative names: `"agents"` (copilot), `"workflows"` (windsurf, kilocode), `"prompts"` (codex, kiro-cli, pi), `"command"` (opencode - singular)
-  - This field enables `--ai-skills` to locate command templates correctly for skill generation
- `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:
+**TOML agent (Gemini):**

 ```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 kiro-cli"),
+"""Gemini CLI integration."""
+
+from ..base import TomlIntegration
+
+
+class GeminiIntegration(TomlIntegration):
+    key = "gemini"
+    config = {
+        "name": "Gemini CLI",
+        "folder": ".gemini/",
+        "commands_subdir": "commands",
+        "install_url": "https://github.com/google-gemini/gemini-cli",
+        "requires_cli": True,
+    }
+    registrar_config = {
+        "dir": ".gemini/commands",
+        "format": "toml",
+        "args": "{{args}}",
+        "extension": ".toml",
+    }
+    context_file = "GEMINI.md"
 ```

-Also update any function docstrings, examples, and error messages that list available agents.
+**Skills agent (Codex):**

-#### 3. Update README Documentation
+```python
+"""Codex CLI integration — skills-based agent."""

-Update the **Supported AI Agents** section in `README.md` to include the new agent:
+from __future__ import annotations

- 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
+from ..base import IntegrationOption, SkillsIntegration

-#### 4. Update Release Package Script

-Modify `.github/workflows/scripts/create-release-packages.sh`:
+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"

-##### Add to ALL_AGENTS array
+    @classmethod
+    def options(cls) -> list[IntegrationOption]:
+        return [
+            IntegrationOption(
+                "--skills",
+                is_flag=True,
+                default=True,
+                help="Install as agent skills (default for Codex)",
+            ),
+        ]
+```
+
+#### Required fields
+
+| Field | Location | Purpose |
+|---|---|---|
+| `key` | Class attribute | Unique identifier; for CLI-based integrations (`requires_cli: True`), must match the CLI executable name |
+| `config` | Class attribute (dict) | Agent metadata: `name`, `folder`, `commands_subdir`, `install_url`, `requires_cli` |
+| `registrar_config` | Class attribute (dict) | Command output config: `dir`, `format`, `args` placeholder, file `extension` |
+| `context_file` | Class attribute (str or None) | Path to agent context/instructions file (e.g., `"CLAUDE.md"`, `".github/copilot-instructions.md"`) |
+
+**Key design rule:** For CLI-based integrations (`requires_cli: True`), `key` must be the actual executable name (e.g., `"cursor-agent"` not `"cursor"`). This ensures `shutil.which(key)` works for CLI-tool checks without special-case mappings. IDE-based integrations (`requires_cli: False`) should use their canonical identifier (e.g., `"windsurf"`, `"copilot"`).
+
+### 3. Register it
+
+In `src/specify_cli/integrations/__init__.py`, add one import and one `_register()` call inside `_register_builtins()`. Both lists are alphabetical:
+
+```python
+def _register_builtins() -> None:
+    # -- Imports (alphabetical) -------------------------------------------
+    from .claude import ClaudeIntegration
+    # ...
+    from .newagent import NewAgentIntegration   # ← add import
+    # ...
+
+    # -- Registration (alphabetical) --------------------------------------
+    _register(ClaudeIntegration())
+    # ...
+    _register(NewAgentIntegration())            # ← add registration
+    # ...
+```
+
+### 4. Add scripts
+
+Create two thin wrapper scripts in `src/specify_cli/integrations/<package_dir>/scripts/` that delegate to the shared context-update scripts. Each is ~25 lines of boilerplate.
+
+> **Note on `<package_dir>` vs `<key>`:** `<package_dir>` is the Python-safe directory name for your integration — it matches `<key>` exactly when the key contains no hyphens (e.g., key `"gemini"` → `gemini/`), but uses underscores when it does (e.g., key `"kiro-cli"` → `kiro_cli/`). The `IntegrationBase.key` class attribute always retains the original hyphenated value (e.g., `key = "kiro-cli"`), since that is what the CLI and registry use.
+
+**`update-context.sh`:**

 ```bash
-ALL_AGENTS=(claude gemini copilot cursor-agent qwen opencode windsurf kiro-cli)
+#!/usr/bin/env bash
+# update-context.sh — <Agent Name> integration: create/update <context_file>
+set -euo pipefail
+
+_script_dir="$(cd "$(dirname "$0")" && pwd)"
+_root="$_script_dir"
+while [ "$_root" != "/" ] && [ ! -d "$_root/.specify" ]; do _root="$(dirname "$_root")"; done
+if [ -z "${REPO_ROOT:-}" ]; then
+  if [ -d "$_root/.specify" ]; then
+    REPO_ROOT="$_root"
+  else
+    git_root="$(git rev-parse --show-toplevel 2>/dev/null || true)"
+    if [ -n "$git_root" ] && [ -d "$git_root/.specify" ]; then
+      REPO_ROOT="$git_root"
+    else
+      REPO_ROOT="$_root"
+    fi
+  fi
+fi
+
+exec "$REPO_ROOT/.specify/scripts/bash/update-agent-context.sh" <key>
 ```

-##### 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:
+**`update-context.ps1`:**

 ```powershell
-$windsurfFile = Join-Path $repoRoot '.windsurf/rules/specify-rules.md'
-```
+# update-context.ps1 — <Agent Name> integration: create/update <context_file>
+$ErrorActionPreference = 'Stop'

-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 $pair.name }
-        }
-        # Update default creation condition
-    }
-}
-```
-
-#### 6. Update CLI Tool Checks (Optional)
-
-For agents that require CLI tools, add checks in the `check()` command and agent validation:
-
-```python
-# In check() command
-tracker.add("windsurf", "Windsurf IDE (optional)")
-windsurf_ok = check_tool_for_tracker("windsurf", "https://windsurf.com/", tracker)
-
-# In init validation (only if CLI tool required)
-elif selected_ai == "windsurf":
-    if not check_tool("windsurf", "Install from: https://windsurf.com/"):
-        console.print("[red]Error:[/red] Windsurf CLI is required for Windsurf projects")
-        agent_tool_missing = True
-```
-
-**Note**: CLI tool checks are now handled automatically based on the `requires_cli` field in AGENT_CONFIG. No additional code changes needed in the `check()` or `init()` commands - they automatically loop through AGENT_CONFIG and check tools as needed.
-
-## Important Design Decisions
-
-### Using Actual CLI Tool Names as Keys
-
-**CRITICAL**: When adding a new agent to AGENT_CONFIG, always use the **actual executable name** as the dictionary key, not a shortened or convenient version.
-
-**Why this matters:**
-
- The `check_tool()` function uses `shutil.which(tool)` to find executables in the system PATH
- If the key doesn't match the actual CLI tool name, you'll need special-case mappings throughout the codebase
- This creates unnecessary complexity and maintenance burden
-
-**Example - The Cursor Lesson:**
-
-❌ **Wrong approach** (requires special-case mapping):
-
-```python
-AGENT_CONFIG = {
-    "cursor": {  # Shorthand that doesn't match the actual tool
-        "name": "Cursor",
-        # ...
+$scriptDir = Split-Path -Parent $MyInvocation.MyCommand.Definition
+$repoRoot = try { git rev-parse --show-toplevel 2>$null } catch { $null }
+if (-not $repoRoot -or -not (Test-Path (Join-Path $repoRoot '.specify'))) {
+    $repoRoot = $scriptDir
+    $fsRoot = [System.IO.Path]::GetPathRoot($repoRoot)
+    while ($repoRoot -and $repoRoot -ne $fsRoot -and -not (Test-Path (Join-Path $repoRoot '.specify'))) {
+        $repoRoot = Split-Path -Parent $repoRoot
    }
 }

-# Then you need special cases everywhere:
-cli_tool = agent_key
-if agent_key == "cursor":
-    cli_tool = "cursor-agent"  # Map to the real tool name
+& "$repoRoot/.specify/scripts/powershell/update-agent-context.ps1" -AgentType <key>
 ```

-✅ **Correct approach** (no mapping needed):
+Replace `<key>` with your integration key and `<Agent Name>` / `<context_file>` with the appropriate values.

-```python
-AGENT_CONFIG = {
-    "cursor-agent": {  # Matches the actual executable name
-        "name": "Cursor",
-        # ...
-    }
-}
+You must also add the agent to the shared context-update scripts so the shared dispatcher recognises the new key:

-# No special cases needed - just use agent_key directly!
+- **`scripts/bash/update-agent-context.sh`** — add a file-path variable and a case in `update_specific_agent()`.
+- **`scripts/powershell/update-agent-context.ps1`** — add a file-path variable, add the new key to the `AgentType` parameter's `[ValidateSet(...)]`, add a switch case in `Update-SpecificAgent`, and add an entry in `Update-AllExistingAgents`.
+
+### 5. Test it
+
+```bash
+# Install into a test project
+specify init my-project --integration <key>
+
+# Verify files were created in the commands directory configured by
+# config["folder"] + config["commands_subdir"] (for example, .windsurf/workflows/)
+ls -R my-project/.windsurf/workflows/
+
+# Uninstall cleanly
+cd my-project && specify integration uninstall <key>
 ```

-**Benefits of this approach:**
+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:

- 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
+```bash
+pytest tests/integrations/test_integration_<key_with_underscores>.py -v
+```

-#### 7. Update Devcontainer files (Optional)
+### 6. Optional overrides
+
+The base classes handle most work automatically. Override only when the agent deviates from standard patterns:
+
+| Override | When to use | Example |
+|---|---|---|
+| `command_filename(template_name)` | Custom file naming or extension | Copilot → `speckit.{name}.agent.md` |
+| `options()` | Integration-specific CLI flags via `--integration-options` | Codex → `--skills` flag |
+| `setup()` | Custom install logic (companion files, settings merge) | Copilot → `.agent.md` + `.prompt.md` + `.vscode/settings.json` |
+| `teardown()` | Custom uninstall logic | Rarely needed; base handles manifest-tracked files |
+
+**Example — Copilot (fully custom `setup`):**
+
+Copilot extends `IntegrationBase` directly because it creates `.agent.md` commands, companion `.prompt.md` files, and merges `.vscode/settings.json`. See `src/specify_cli/integrations/copilot/__init__.py` for the full implementation.
+
+### 7. Update Devcontainer files (Optional)

 For agents that have VS Code extensions or require CLI installation, update the devcontainer configuration files:

 ## Argument Patterns

-Different agents use different argument placeholders:
+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**: `$ARGUMENTS`
- **TOML-based**: `{{args}}`
+- **Markdown/prompt-based**: `$ARGUMENTS` (default for most markdown agents)
+- **TOML-based**: `{{args}}` (e.g., Gemini)

+- **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)

-## Testing New Agent Integration
+## Special Processing Requirements

-1. **Build test**: Run package creation script locally
-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
+
+### Forge Integration
+
+Forge has special frontmatter and argument requirements:
+- Uses `{{parameters}}` instead of `$ARGUMENTS`
+- Strips `handoffs` frontmatter key (Forge-specific collaboration feature)
+- Injects `name` field into frontmatter when missing
+
+Implementation: Extends `MarkdownIntegration` with custom `setup()` method that:
+1. Inherits standard template processing from `MarkdownIntegration`
+2. Adds extra `$ARGUMENTS` → `{{parameters}}` replacement after template processing
+3. Applies Forge-specific transformations via `_apply_forge_transformations()`
+4. Strips `handoffs` frontmatter key
+5. Injects missing `name` fields
+6. Ensures the shared `update-agent-context.*` scripts include a `forge` case that maps context updates to `AGENTS.md` and lists `forge` in their usage/help text
+
+### Goose Integration
+
+Goose is a YAML-format agent using Block's recipe system:
+- Uses `.goose/recipes/` directory for YAML recipe files
+- Uses `{{args}}` argument placeholder
+- Produces YAML with `prompt: |` block scalar for command content
+
+Implementation: Extends `YamlIntegration` (parallel to `TomlIntegration`):
+1. Processes templates through the standard placeholder pipeline
+2. Extracts title and description from frontmatter
+3. Renders output as Goose recipe YAML (version, title, description, author, extensions, activities, prompt)
+4. Uses `yaml.safe_dump()` for header fields to ensure proper escaping
+5. Context updates map to `AGENTS.md` (shared with opencode/codex/pi/forge)

 ## Common Pitfalls

-1. **Using shorthand keys 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. **Create release packages**
+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.

+
+#### Manual testing process
+
+Any change that affects a slash command's behavior requires manually testing that command through an AI 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.

+
+#### Determining which tests to run
+
+Copy this prompt into your agent. Include the agent's response (selected tests plus a brief explanation of the mapping) in your PR.
+
+~~~text
+Read 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).
+

+|---|---|---|---|
+| (path) | (command) | T# | (reason) |
+
+### Required tests

 - **[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.

 ## 🧩 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:

-**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. **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.

 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.

+# Core Commands
+
+The core `specify` commands handle project initialization, system checks, and version information.
+
+## Initialize a Project
+
+```bash
+specify init [<project_name>]
+```
+
+| Option                   | Description                                                              |
+| ------------------------ | ------------------------------------------------------------------------ |
+| `--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.
+
+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.
+
+### 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
+```
+
+### Environment Variables
+
+| Variable          | Description                                                              |
+| ----------------- | ------------------------------------------------------------------------ |
+| `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.
+
+## Version Information
+
+```bash
+specify version
+```
+
+Displays the Spec Kit CLI version, Python version, platform, and architecture.
+
+A quick version check is also available via:
+
+```bash
+specify --version
+specify -V

+# 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.
+
+## Install an Integration
+
+```bash
+specify integration install <key>
+```
+
+| Option                   | Description                                                              |
+| ------------------------ | ------------------------------------------------------------------------ |
+| `--script sh\|ps`        | Script type: `sh` (bash/zsh) or `ps` (PowerShell)                        |
+| `--integration-options`  | Integration-specific options (e.g. `--integration-options="--commands-dir .myagent/cmds"`) |
+
+Installs the specified integration into the current project. Fails if another integration is already installed — use `switch` instead. If the installation fails partway through, it automatically rolls back to a clean state.
+
+> **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                         |
+| `--integration-options`  | Options for the target integration                                       |
+
+Equivalent to running `uninstall` followed by `install` in a single step.
+
+## 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 the current integration with updated templates and commands (e.g., after upgrading Spec Kit). Defaults to the currently installed integration; if a key is provided, it must match the installed one — otherwise the command fails and suggests using `switch` instead. 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.
+
+## 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 use multiple integrations at the same time?
+
+No. Only one AI coding agent integration can be installed per project. Use `specify integration switch <key>` to change to a different AI coding agent.
+
+### 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 the same integration's templates. Use `switch` when you want to change to a different AI coding agent.

+# 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

+    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.
+

+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

+    B -- approve --> C["plan<br/>(command)"]

+    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.

+# 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 |

+
+## 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

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

+# Initialize Git Repository
+
+Initialize a Git repository in the current project directory if one does not already exist.
+
+## Execution
+
+Run the appropriate script from the project root:
+
+- **Bash**: `.specify/extensions/git/scripts/bash/initialize-repo.sh`
+- **PowerShell**: `.specify/extensions/git/scripts/powershell/initialize-repo.ps1`

+
+The script handles all checks internally:
+- Skips if Git is not available
+- Skips if already inside a Git repository
+- Runs `git init`, `git add .`, and `git commit` with an initial commit message
+
+## Customization
+
+Replace the script to add project-specific Git initialization steps:
+- Custom `.gitignore` templates
+- Default branch naming (`git config init.defaultBranch`)
+- Git LFS setup
+- Git hooks installation
+- Commit signing configuration
+- Git Flow initialization

+## Output
+
+On success:
+- `✓ Git repository initialized`

+## Graceful Degradation

+If Git is not installed:
+- Warn the user
+- Skip repository initialization
+- The project continues to function without Git (specs can still be created under `specs/`)
+
+If Git is installed but `git init`, `git add .`, or `git commit` fails:
+- Surface the error to the user
+- Stop this command rather than continuing with a partially initialized repository

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

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

+# 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",
+  "catalog_url": "https://...",

+      "repository": "https://github.com/my-org/speckit-my-agent",
+      "tags": ["cli"]
+    }
+  }
+}
+```
+
+### Required Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `schema_version` | string | Must be `"1.0"` |

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