fix: correct PresetError docstring from template to preset

- Fix PS Resolve-Template fallback to skip dot-prefixed dirs (.cache)
- Rename _catalog to _catalog_name for consistency with extension system
- Enforce install_allowed policy in CLI preset add and download_pack()
- Fix shell injection: pass registry path via env var instead of string interpolation

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

+- feat(presets): Pluggable preset system with preset catalog and template resolver
+- Preset manifest (`preset.yml`) with validation for artifact, command, and script types
+- `PresetManifest`, `PresetRegistry`, `PresetManager`, `PresetCatalog`, `PresetResolver` classes in `src/specify_cli/presets.py`

+## [0.1.14] - 2026-03-09
+
+### Added
+
+- feat: add Tabnine CLI agent support
+- **Multi-Catalog Support (#1707)**: Extension catalog system now supports multiple active catalogs simultaneously via a catalog stack
+  - New `specify extension catalog list` command lists all active catalogs with name, URL, priority, and `install_allowed` status
+  - New `specify extension catalog add` and `specify extension catalog remove` commands for project-scoped catalog management
+  - Default built-in stack includes `catalog.json` (default, installable) and `catalog.community.json` (community, discovery only) — community extensions are now surfaced in search results out of the box
+  - `specify extension search` aggregates results across all active catalogs, annotating each result with source catalog
+  - `specify extension add` enforces `install_allowed` policy — extensions from discovery-only catalogs cannot be installed directly
+  - Project-level `.specify/extension-catalogs.yml` and user-level `~/.specify/extension-catalogs.yml` config files supported, with project-level taking precedence
+  - `SPECKIT_CATALOG_URL` environment variable still works for backward compatibility (replaces full stack with single catalog)
+  - All catalog URLs require HTTPS (HTTP allowed for localhost development)
+  - New `CatalogEntry` dataclass in `extensions.py` for catalog stack representation
+  - Per-URL hash-based caching for non-default catalogs; legacy cache preserved for default catalog
+  - Higher-priority catalogs win on merge conflicts (same extension id in multiple catalogs)
+  - 13 new tests covering catalog stack resolution, merge conflicts, URL validation, and `install_allowed` enforcement
+  - Updated RFC, Extension User Guide, and Extension API Reference documentation

+## [0.1.13] - 2026-03-03
 
 ### Fixed
 
-- **Python 3.14 / Homebrew compatibility**: Added explicit `click>=8.1` dependency so the resolver always selects a Click version compatible with Python 3.14 and avoids errors such as `TypeError: ParamType.get_metavar() got an unexpected keyword argument 'ctx'` when an older Click would otherwise be used. Note that broader uv/Homebrew environment isolation or `sys.path` bleed issues (see [#1631](https://github.com/github/spec-kit/issues/1631)) may still require environment-level workarounds.
-
-## [0.1.1] - 2026-02-13
-
-### Added
-
-- **Agent Skills Installation**: New `--ai-skills` CLI option to install Prompt.MD templates as agent skills following [agentskills.io specification](https://agentskills.io/specification)
-  - Skills are installed to agent-specific directories (e.g., `.claude/skills/`, `.gemini/skills/`, `.github/skills/`)
-  - Codex uses `.agents/skills/` following Codex agent directory conventions
-  - Default fallback directory is `.agents/skills/` for agents without a specific mapping
-  - Requires `--ai` flag to be specified
-  - Converts all 9 spec-kit command templates (specify, plan, tasks, implement, analyze, clarify, constitution, checklist, taskstoissues) to properly formatted SKILL.md files
-  - **New projects**: command files are not installed when `--ai-skills` is used (skills replace commands)
-  - **Existing repos** (`--here`): pre-existing command files are preserved — no breaking changes
-  - `pyyaml` dependency (already present) used for YAML frontmatter parsing
-- **Unit tests** for `install_ai_skills`, `_get_skills_dir`, and `--ai-skills` CLI validation (51 test cases covering all 18 supported agents)
-
-## [0.1.0] - 2026-01-28

+- **Copilot Extension Commands Not Visible**: Fixed extension commands not appearing in GitHub Copilot when installed via `specify extension add --dev`
+  - Changed Copilot file extension from `.md` to `.agent.md` in `CommandRegistrar.AGENT_CONFIGS` so Copilot recognizes agent files
+  - Added generation of companion `.prompt.md` files in `.github/prompts/` during extension command registration, matching the release packaging behavior
+  - Added cleanup of `.prompt.md` companion files when removing extensions via `specify extension remove`
+- Fixed a syntax regression in `src/specify_cli/__init__.py` in `_build_ai_assistant_help()` that broke `ruff` and `pytest` collection in CI.
+## [0.1.12] - 2026-03-02
 
 ### Changed

-- Adds support for the version command. ([#486](https://github.com/github/spec-kit/issues/486))
-- Fixes potential bug with the `create-new-feature.ps1` script that ignores existing feature branches when determining next feature number ([#975](https://github.com/github/spec-kit/issues/975))
-- Add graceful fallback and logging for GitHub API rate-limiting during template fetch ([#970](https://github.com/github/spec-kit/issues/970))

-
-## [0.0.20] - 2025-10-14
-
-### Added
-
-- **Intelligent Branch Naming**: `create-new-feature` scripts now support `--short-name` parameter for custom branch names
-  - When `--short-name` provided: Uses the custom name directly (cleaned and formatted)
-  - When omitted: Automatically generates meaningful names using stop word filtering and length-based filtering
-  - Filters out common stop words (I, want, to, the, for, etc.)
-  - Removes words shorter than 3 characters (unless they're uppercase acronyms)
-  - Takes 3-4 most meaningful words from the description
-  - **Enforces GitHub's 244-byte branch name limit** with automatic truncation and warnings
-  - Examples:
-    - "I want to create user authentication" → `001-create-user-authentication`
-    - "Implement OAuth2 integration for API" → `001-implement-oauth2-integration-api`
-    - "Fix payment processing bug" → `001-fix-payment-processing`
-    - Very long descriptions are automatically truncated at word boundaries to stay within limits
-  - Designed for AI agents to provide semantic short names while maintaining standalone usability
-
-### Changed
-
-- Enhanced help documentation for `create-new-feature.sh` and `create-new-feature.ps1` scripts with examples
-- Branch names now validated against GitHub's 244-byte limit with automatic truncation if needed
-

-- Implementation command now ensures that the correct ignore files are added (thank you to [@sigent-amazon](https://github.com/sigent-amazon) for the contribution).
-
-## [0.0.18] - 2025-10-06
-
-### Added
-
-- Support for using `.` as a shorthand for current directory in `specify init .` command, equivalent to `--here` flag but more intuitive for users.
-- Use the `/speckit.` command prefix to easily discover Spec Kit-related commands.
-- Refactor the prompts and templates to simplify their capabilities and how they are tracked. No more polluting things with tests when they are not needed.
-- Ensure that tasks are created per user story (simplifies testing and validation).
-- Add support for Visual Studio Code prompt shortcuts and automatic script execution.
-
-### Changed
-
-- All command files now prefixed with `speckit.` (e.g., `speckit.specify.md`, `speckit.plan.md`) for better discoverability and differentiation in IDE/CLI command palettes and file explorers
-
-## [0.0.17] - 2025-09-22
-
-### Added
-
-- New `/clarify` command template to surface up to 5 targeted clarification questions for an existing spec and persist answers into a Clarifications section in the spec.
-- New `/analyze` command template providing a non-destructive cross-artifact discrepancy and alignment report (spec, clarifications, plan, tasks, constitution) inserted after `/tasks` and before `/implement`.
-  - Note: Constitution rules are explicitly treated as non-negotiable; any conflict is a CRITICAL finding requiring artifact remediation, not weakening of principles.
-
-## [0.0.16] - 2025-09-22
-
-### Added
-
-- `--force` flag for `init` command to bypass confirmation when using `--here` in a non-empty directory and proceed with merging/overwriting files.

+  - Added validation to detect when `--ai` or `--ai-commands-dir` incorrectly consume following flags like `--here` or `--ai-skills`
+  - Now provides clear error messages: "Invalid value for --ai: '--here'"
+  - Includes helpful hints suggesting proper usage and listing available agents
+  - Commands like `specify init --ai-skills --ai --here` now fail with actionable feedback instead of confusing "Must specify project name" errors
+  - Added comprehensive test suite (5 new tests) to prevent regressions
+
+## [0.1.5] - 2026-02-21
+
+### Fixed
+
+- **AI Skills Installation Bug (#1658)**: Fixed `--ai-skills` flag not generating skill files for GitHub Copilot and other agents with non-standard command directory structures
+  - Added `commands_subdir` field to `AGENT_CONFIG` to explicitly specify the subdirectory name for each agent
+  - Affected agents now work correctly: copilot (`.github/agents/`), opencode (`.opencode/command/`), windsurf (`.windsurf/workflows/`), codex (`.codex/prompts/`), kilocode (`.kilocode/workflows/`), q (`.amazonq/prompts/`), and agy (`.agent/workflows/`)
+  - The `install_ai_skills()` function now uses the correct path for all agents instead of assuming `commands/` for everyone
+
+## [0.1.4] - 2026-02-20
+
+### Fixed
+
+- **Qoder CLI detection**: Renamed `AGENT_CONFIG` key from `"qoder"` to `"qodercli"` to match the actual executable name, fixing `specify check` and `specify init --ai` detection failures
+
+## [0.1.3] - 2026-02-20
+
+### Added
+
+- **Generic Agent Support**: Added `--ai generic` option for unsupported AI agents ("bring your own agent")
+  - Requires `--ai-commands-dir <path>` to specify where the agent reads commands from
+  - Generates Markdown commands with `$ARGUMENTS` format (compatible with most agents)
+  - Example: `specify init my-project --ai generic --ai-commands-dir .myagent/commands/`
+  - Enables users to start with Spec Kit immediately while their agent awaits formal support

+## Excluding Files with `.extensionignore`
+
+Extension authors can create a `.extensionignore` file in the extension root to exclude files and folders from being copied when a user installs the extension with `specify extension add`. This is useful for keeping development-only files (tests, CI configs, docs source, etc.) out of the installed copy.
+
+### Format
+
+The file uses `.gitignore`-compatible patterns (one per line), powered by the [`pathspec`](https://pypi.org/project/pathspec/) library:
+
+- Blank lines are ignored
+- Lines starting with `#` are comments
+- `*` matches anything **except** `/` (does not cross directory boundaries)
+- `**` matches zero or more directories (e.g., `docs/**/*.draft.md`)
+- `?` matches any single character except `/`
+- A trailing `/` restricts a pattern to directories only
+- Patterns containing `/` (other than a trailing slash) are anchored to the extension root
+- Patterns without `/` match at any depth in the tree
+- `!` negates a previously excluded pattern (re-includes a file)
+- Backslashes in patterns are normalised to forward slashes for cross-platform compatibility
+- The `.extensionignore` file itself is always excluded automatically
+
+### Example
+
+```gitignore
+# .extensionignore
+
+# Development files
+tests/
+.github/
+.gitignore
+
+# Build artifacts
+__pycache__/
+*.pyc
+dist/
+
+# Documentation source (keep only the built README)
+docs/
+CONTRIBUTING.md
+```
+
+### Pattern Matching
+
+| Pattern | Matches | Does NOT match |
+|---------|---------|----------------|
+| `*.pyc` | Any `.pyc` file in any directory | — |
+| `tests/` | The `tests` directory (and all its contents) | A file named `tests` |
+| `docs/*.draft.md` | `docs/api.draft.md` (directly inside `docs/`) | `docs/sub/api.draft.md` (nested) |
+| `.env` | The `.env` file at any level | — |
+| `!README.md` | Re-includes `README.md` even if matched by an earlier pattern | — |
+| `docs/**/*.draft.md` | `docs/api.draft.md`, `docs/sub/api.draft.md` | — |
+
+### Unsupported Features
+
+The following `.gitignore` features are **not applicable** in this context:
+
+- **Multiple `.extensionignore` files**: Only a single file at the extension root is supported (`.gitignore` supports files in subdirectories)
+- **`$GIT_DIR/info/exclude` and `core.excludesFile`**: These are Git-specific and have no equivalent here
+- **Negation inside excluded directories**: Because file copying uses `shutil.copytree`, excluding a directory prevents recursion into it entirely. A negation pattern cannot re-include a file inside a directory that was itself excluded. For example, the combination `tests/` followed by `!tests/important.py` will **not** preserve `tests/important.py` — the `tests/` directory is skipped at the root level and its contents are never evaluated. To work around this, exclude the directory's contents individually instead of the directory itself (e.g., `tests/*.pyc` and `tests/.cache/` rather than `tests/`).

+## Extension Catalogs
+
+Spec Kit uses a **catalog stack** — an ordered list of catalogs searched simultaneously. By default, two catalogs are active:
+
+| Priority | Catalog | Install Allowed | Purpose |
+|----------|---------|-----------------|---------|
+| 1 | `catalog.json` (default) | ✅ Yes | Curated extensions available for installation |
+| 2 | `catalog.community.json` (community) | ❌ No (discovery only) | Browse community extensions |

+# Add a discovery-only catalog
+specify extension catalog add \
+  --name "partner" \
+  --priority 5 \
+  https://partner.example.com/spec-kit/catalog.json
+```
+
+This creates or updates `.specify/extension-catalogs.yml`.
+
+### Removing a Catalog
+
+```bash
+specify extension catalog remove internal
+```
+
+### Manual Config File
+
+You can also edit `.specify/extension-catalogs.yml` directly:
+
+```yaml
+catalogs:
+  - name: "default"
+    url: "https://raw.githubusercontent.com/github/spec-kit/main/extensions/catalog.json"

+A user-level equivalent lives at `~/.specify/extension-catalogs.yml`. Project-level config takes full precedence when it contains one or more catalog entries. An empty `catalogs: []` list falls back to built-in defaults.

+
+Extension system for [Spec Kit](https://github.com/github/spec-kit) - add new functionality without bloating the core framework.
+
+## Extension Catalogs
+
+Spec Kit provides two catalog files with different purposes:
+
+### Your Catalog (`catalog.json`)
+
+- **Purpose**: Default upstream catalog of extensions used by the Spec Kit CLI
+- **Default State**: Empty by design in the upstream project - you or your organization populate a fork/copy with extensions you trust
+- **Location (upstream)**: `extensions/catalog.json` in the GitHub-hosted spec-kit repo
+- **CLI Default**: The `specify extension` commands use the upstream catalog URL by default, unless overridden
+- **Org Catalog**: Point `SPECKIT_CATALOG_URL` at your organization's fork or hosted catalog JSON to use it instead of the upstream default
+- **Customization**: Copy entries from the community catalog into your org catalog, or add your own extensions directly
+
+**Example override:**
+```bash
+# Override the default upstream catalog with your organization's catalog
+export SPECKIT_CATALOG_URL="https://your-org.com/spec-kit/catalog.json"
+specify extension search  # Now uses your organization's catalog instead of the upstream default
+```
+
+### Community Reference Catalog (`catalog.community.json`)
+
+- **Purpose**: Browse available community-contributed extensions
+- **Status**: Active - contains extensions submitted by the community
+- **Location**: `extensions/catalog.community.json`
+- **Usage**: Reference catalog for discovering available extensions
+- **Submission**: Open to community contributions via Pull Request
+
+**How It Works:**
+
+## Making Extensions Available
+
+You control which extensions your team can discover and install:
+
+### Option 1: Curated Catalog (Recommended for Organizations)
+
+Populate your `catalog.json` with approved extensions:
+
+1. **Discover** extensions from various sources:
+   - Browse `catalog.community.json` for community extensions
+   - Find private/internal extensions in your organization's repos
+   - Discover extensions from trusted third parties
+2. **Review** extensions and choose which ones you want to make available
+3. **Add** those extension entries to your own `catalog.json`
+4. **Team members** can now discover and install them:
+   - `specify extension search` shows your curated catalog
+   - `specify extension add <name>` installs from your catalog
+
+**Benefits**: Full control over available extensions, team consistency, organizational approval workflow
+
+**Example**: Copy an entry from `catalog.community.json` to your `catalog.json`, then your team can discover and install it by name.
+
+### Option 2: Direct URLs (For Ad-hoc Use)
+
+Skip catalog curation - team members install directly using URLs:
+
+```bash
+specify extension add --from https://github.com/org/spec-kit-ext/archive/refs/tags/v1.0.0.zip
+```
+
+**Benefits**: Quick for one-off testing or private extensions
+
+**Tradeoff**: Extensions installed this way won't appear in `specify extension search` for other team members unless you also add them to your `catalog.json`.
+
+## Available Community Extensions
+
+The following community-contributed extensions are available in [`catalog.community.json`](catalog.community.json):
+
+| Extension | Purpose | URL |
+|-----------|---------|-----|
+| Azure DevOps Integration | Sync user stories and tasks to Azure DevOps work items using OAuth authentication | [spec-kit-azure-devops](https://github.com/pragya247/spec-kit-azure-devops) |

+
+## Adding Your Extension
+
+### Submission Process
+
+To add your extension to the community catalog:
+
+1. **Prepare your extension** following the [Extension Development Guide](EXTENSION-DEVELOPMENT-GUIDE.md)
+2. **Create a GitHub release** for your extension
+3. **Submit a Pull Request** that:
+   - Adds your extension to `extensions/catalog.community.json`
+   - Updates this README with your extension in the Available Extensions table
+4. **Wait for review** - maintainers will review and merge if criteria are met
+
+See the [Extension Publishing Guide](EXTENSION-PUBLISHING-GUIDE.md) for detailed step-by-step instructions.
+
+### Submission Checklist
+
+Before submitting, ensure:
+
+- ✅ Valid `extension.yml` manifest
+- ✅ Complete README with installation and usage instructions
+- ✅ LICENSE file included
+- ✅ GitHub release created with semantic version (e.g., v1.0.0)
+- ✅ Extension tested on a real project
+- ✅ All commands working as documented
+
+## Installing Extensions
+Once extensions are available (either in your catalog or via direct URL), install them:
+
+```bash
+# From your curated catalog (by name)
+specify extension search                  # See what's in your catalog
+specify extension add <extension-name>    # Install by name
+
+# Direct from URL (bypasses catalog)
+specify extension add --from https://github.com/<org>/<repo>/archive/refs/tags/<version>.zip
+
+# List installed extensions
+specify extension list
+```

-### Central Catalog
+### Dual Catalog System
+
+Spec Kit uses two catalog files with different purposes:
+
+#### User Catalog (`catalog.json`)
 
 **URL**: `https://raw.githubusercontent.com/github/spec-kit/main/extensions/catalog.json`
 
-**Format**:
+- **Purpose**: Organization's curated catalog of approved extensions
+- **Default State**: Empty by design - users populate with extensions they trust
+- **Usage**: Primary catalog (priority 1, `install_allowed: true`) in the default stack
+- **Control**: Organizations maintain their own fork/version for their teams
+
+#### Community Reference Catalog (`catalog.community.json`)
+
+**URL**: `https://raw.githubusercontent.com/github/spec-kit/main/extensions/catalog.community.json`
+
+- **Purpose**: Reference catalog of available community-contributed extensions
+- **Verification**: Community extensions may have `verified: false` initially
+- **Status**: Active - open for community contributions
+- **Submission**: Via Pull Request following the Extension Publishing Guide
+- **Usage**: Secondary catalog (priority 2, `install_allowed: false`) in the default stack — discovery only
+
+**How It Works (default stack):**
+
+1. **Discover**: `specify extension search` searches both catalogs — community extensions appear automatically
+2. **Review**: Evaluate community extensions for security, quality, and organizational fit
+3. **Curate**: Copy approved entries from community catalog to your `catalog.json`, or add to `.specify/extension-catalogs.yml` with `install_allowed: true`
+4. **Install**: Use `specify extension add <name>` — only allowed from `install_allowed: true` catalogs
+
+This approach gives organizations full control over which extensions can be installed while still providing community discoverability out of the box.

 ### Custom Catalogs

-```bash

+#### Catalog Stack Resolution
 
-# Set as default

+4. **Built-in default stack** — `catalog.json` (install_allowed: true) + `catalog.community.json` (install_allowed: false)
+
+#### Default Built-in Stack

+| 2 | `catalog.community.json` (community) | `false` | Discovery only — browse but not install |
+
+This means `specify extension search` surfaces community extensions out of the box, while `specify extension add` is still restricted to entries from catalogs with `install_allowed: true`.
+
+#### `.specify/extension-catalogs.yml` Config File
+
+```yaml
+catalogs:
+  - name: "default"
+    url: "https://raw.githubusercontent.com/github/spec-kit/main/extensions/catalog.json"
+    priority: 1          # Highest — only approved entries can be installed
+    install_allowed: true
+    description: "Built-in catalog of installable extensions"
+
+  - name: "internal"
+    url: "https://internal.company.com/spec-kit/catalog.json"
+    priority: 2
+    install_allowed: true
+    description: "Internal company extensions"
+
+  - name: "community"
+    url: "https://raw.githubusercontent.com/github/spec-kit/main/extensions/catalog.community.json"
+    priority: 3          # Lowest — discovery only, not installable
+    install_allowed: false
+    description: "Community-contributed extensions (discovery only)"
 ```
 
-**Catalog priority**:
+A user-level equivalent lives at `~/.specify/extension-catalogs.yml`. When a project-level config is present with one or more catalog entries, it takes full control and the built-in defaults are not applied. An empty `catalogs: []` list is treated the same as no config file, falling back to defaults.
 
-1. Project-specific catalog (`.specify/extension-catalogs.yml`)
-2. User-level catalog (`~/.specify/extension-catalogs.yml`)
-3. Default GitHub catalog
+#### Catalog CLI Commands
+
+```bash
+# List active catalogs with name, URL, priority, and install_allowed
+specify extension catalog list
+
+# Add a catalog (project-scoped)
+specify extension catalog add --name "internal" --install-allowed \
+  https://internal.company.com/spec-kit/catalog.json
+
+# Add a discovery-only catalog
+specify extension catalog add --name "community" \
+  https://raw.githubusercontent.com/github/spec-kit/main/extensions/catalog.community.json
+
+# Remove a catalog
+specify extension catalog remove internal
+
+# Show which catalog an extension came from
+specify extension info jira
+# → Source catalog: default
+```
+
+#### Merge Conflict Resolution
+
+When the same extension `id` appears in multiple catalogs, the higher-priority (lower priority number) catalog wins. Extensions from lower-priority catalogs with the same `id` are ignored.
+
+#### `install_allowed: false` Behavior
+
+Extensions from discovery-only catalogs are shown in `specify extension search` results but cannot be installed directly:
+
+```
+⚠  'linear' is available in the 'community' catalog but installation is not allowed from that catalog.
+
+To enable installation, add 'linear' to an approved catalog (install_allowed: true) in .specify/extension-catalogs.yml.
+```
+
+#### `SPECKIT_CATALOG_URL` (Backward Compatibility)
+
+The `SPECKIT_CATALOG_URL` environment variable still works — it is treated as a single `install_allowed: true` catalog, **replacing both defaults** for full backward compatibility:
+
+```bash
+# Point to your organization's catalog
+export SPECKIT_CATALOG_URL="https://internal.company.com/spec-kit/catalog.json"
+
+# All extension commands now use your custom catalog
+specify extension search       # Uses custom catalog
+specify extension add jira     # Installs from custom catalog
+```
+
+**Requirements:**
+- URL must use HTTPS (HTTP only allowed for localhost testing)
+- Catalog must follow the standard catalog.json schema
+- Must be publicly accessible or accessible within your network
+
+**Example for testing:**
+```bash
+# Test with localhost during development
+export SPECKIT_CATALOG_URL="http://localhost:8000/catalog.json"
+specify extension search
+```

+# Preset System Architecture
+
+This document describes the internal architecture of the preset system — how template resolution, command registration, and catalog management work under the hood.
+
+For usage instructions, see [README.md](README.md).
+
+## Template Resolution
+
+When Spec Kit needs a template (e.g. `spec-template`), the `PresetResolver` walks a priority stack and returns the first match:
+
+```mermaid
+flowchart TD
+    A["resolve_template('spec-template')"] --> B{Override exists?}
+    B -- Yes --> C[".specify/templates/overrides/spec-template.md"]
+    B -- No --> D{Preset provides it?}
+    D -- Yes --> E[".specify/presets/‹preset-id›/templates/spec-template.md"]
+    D -- No --> F{Extension provides it?}
+    F -- Yes --> G[".specify/extensions/‹ext-id›/templates/spec-template.md"]
+    F -- No --> H[".specify/templates/spec-template.md"]
+
+    E -- "multiple presets?" --> I["lowest priority number wins"]
+    I --> E
+
+    style C fill:#4caf50,color:#fff
+    style E fill:#2196f3,color:#fff
+    style G fill:#ff9800,color:#fff
+    style H fill:#9e9e9e,color:#fff
+```
+
+| Priority | Source | Path | Use case |
+|----------|--------|------|----------|
+| 1 (highest) | Override | `.specify/templates/overrides/` | One-off project-local tweaks |
+| 2 | Preset | `.specify/presets/<id>/templates/` | Shareable, stackable customizations |
+| 3 | Extension | `.specify/extensions/<id>/templates/` | Extension-provided templates |
+| 4 (lowest) | Core | `.specify/templates/` | Shipped defaults |
+
+When multiple presets are installed, they're sorted by their `priority` field (lower number = higher precedence). This is set via `--priority` on `specify preset add`.
+
+The resolution is implemented three times to ensure consistency:
+- **Python**: `PresetResolver` in `src/specify_cli/presets.py`
+- **Bash**: `resolve_template()` in `scripts/bash/common.sh`
+- **PowerShell**: `Resolve-Template` in `scripts/powershell/common.ps1`
+
+## Command Registration
+
+When a preset is installed with `type: "command"` entries, the `PresetManager` registers them into all detected agent directories using the shared `CommandRegistrar` from `src/specify_cli/agents.py`.
+
+```mermaid
+flowchart TD
+    A["specify preset add my-preset"] --> B{Preset has type: command?}
+    B -- No --> Z["done (templates only)"]
+    B -- Yes --> C{Extension command?}
+    C -- "speckit.myext.cmd\n(3+ dot segments)" --> D{Extension installed?}
+    D -- No --> E["skip (extension not active)"]
+    D -- Yes --> F["register command"]
+    C -- "speckit.specify\n(core command)" --> F
+    F --> G["detect agent directories"]
+    G --> H[".claude/commands/"]
+    G --> I[".gemini/commands/"]
+    G --> J[".github/agents/"]
+    G --> K["... (17+ agents)"]
+    H --> L["write .md (Markdown format)"]
+    I --> M["write .toml (TOML format)"]
+    J --> N["write .agent.md + .prompt.md"]
+
+    style E fill:#ff5722,color:#fff
+    style L fill:#4caf50,color:#fff
+    style M fill:#4caf50,color:#fff
+    style N fill:#4caf50,color:#fff
+```
+
+### Extension safety check
+
+Command names follow the pattern `speckit.<ext-id>.<cmd-name>`. When a command has 3+ dot segments, the system extracts the extension ID and checks if `.specify/extensions/<ext-id>/` exists. If the extension isn't installed, the command is skipped — preventing orphan files referencing non-existent extensions.
+
+Core commands (e.g. `speckit.specify`, with only 2 segments) are always registered.
+
+### Agent format rendering
+
+The `CommandRegistrar` renders commands differently per agent:
+
+| Agent | Format | Extension | Arg placeholder |
+|-------|--------|-----------|-----------------|
+| Claude, Cursor, opencode, Windsurf, etc. | Markdown | `.md` | `$ARGUMENTS` |
+| Copilot | Markdown | `.agent.md` + `.prompt.md` | `$ARGUMENTS` |
+| Gemini, Qwen, Tabnine | TOML | `.toml` | `{{args}}` |
+
+### Cleanup on removal
+
+When `specify preset remove` is called, the registered commands are read from the registry metadata and the corresponding files are deleted from each agent directory, including Copilot companion `.prompt.md` files.
+
+## Catalog System
+
+```mermaid
+flowchart TD
+    A["specify preset search"] --> B["PresetCatalog.get_active_catalogs()"]
+    B --> C{SPECKIT_PRESET_CATALOG_URL set?}
+    C -- Yes --> D["single custom catalog"]
+    C -- No --> E{.specify/preset-catalogs.yml exists?}
+    E -- Yes --> F["project-level catalog stack"]
+    E -- No --> G{"~/.specify/preset-catalogs.yml exists?"}
+    G -- Yes --> H["user-level catalog stack"]
+    G -- No --> I["built-in defaults"]
+    I --> J["default (install allowed)"]
+    I --> K["community (discovery only)"]
+
+    style D fill:#ff9800,color:#fff
+    style F fill:#2196f3,color:#fff
+    style H fill:#2196f3,color:#fff
+    style J fill:#4caf50,color:#fff
+    style K fill:#9e9e9e,color:#fff
+```
+
+Catalogs are fetched with a 1-hour cache (per-URL, SHA256-hashed cache files). Each catalog entry has a `priority` (for merge ordering) and `install_allowed` flag.

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

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

+# Presets
+
+Presets are stackable, priority-ordered collections of template and command overrides for Spec Kit. They let you customize both the artifacts produced by the Spec-Driven Development workflow (specs, plans, tasks, checklists, constitutions) and the commands that guide the LLM in creating them — without forking or modifying core files.
+
+## How It Works
+
+When Spec Kit needs a template (e.g. `spec-template`), it walks a resolution stack:
+
+1. `.specify/templates/overrides/` — project-local one-off overrides
+2. `.specify/presets/<preset-id>/templates/` — installed presets (sorted by priority)
+3. `.specify/extensions/<ext-id>/templates/` — extension-provided templates
+4. `.specify/templates/` — core templates shipped with Spec Kit
+
+If no preset is installed, core templates are used — exactly the same behavior as before presets existed.
+
+For detailed resolution and command registration flows, see [ARCHITECTURE.md](ARCHITECTURE.md).
+
+## Command Overrides
+
+Presets can also override the commands that guide the SDD workflow. Templates define *what* gets produced (specs, plans, constitutions); commands define *how* the LLM produces them (the step-by-step instructions).
+
+When a preset includes `type: "command"` entries, the commands are automatically registered into all detected agent directories (`.claude/commands/`, `.gemini/commands/`, etc.) in the correct format (Markdown or TOML with appropriate argument placeholders). When the preset is removed, the registered commands are cleaned up.
+
+## Quick Start
+
+```bash
+# Search available presets
+specify preset search
+
+# Install a preset from the catalog
+specify preset add healthcare-compliance
+
+# Install from a local directory (for development)
+specify preset add --dev ./my-preset
+
+# Install with a specific priority (lower = higher precedence)
+specify preset add healthcare-compliance --priority 5
+
+# List installed presets
+specify preset list
+
+# See which template a name resolves to
+specify preset resolve spec-template
+
+# Get detailed info about a preset
+specify preset info healthcare-compliance
+
+# Remove a preset
+specify preset remove healthcare-compliance
+```
+
+## Stacking Presets
+
+Multiple presets can be installed simultaneously. The `--priority` flag controls which one wins when two presets provide the same template (lower number = higher precedence):
+
+```bash
+specify preset add enterprise-safe --priority 10      # base layer
+specify preset add healthcare-compliance --priority 5  # overrides enterprise-safe
+specify preset add pm-workflow --priority 1            # overrides everything
+```
+
+Presets **override**, they don't merge. If two presets both provide `spec-template`, the one with the lowest priority number wins entirely.
+
+## Catalog Management
+
+Presets are discovered through catalogs. By default, Spec Kit uses the official and community catalogs:
+
+```bash
+# List active catalogs
+specify preset catalog list
+
+# Add a custom catalog
+specify preset catalog add https://example.com/catalog.json --name my-org --install-allowed
+
+# Remove a catalog
+specify preset catalog remove my-org
+```
+
+## Creating a Preset
+
+See [scaffold/](scaffold/) for a scaffold you can copy to create your own preset.
+
+1. Copy `scaffold/` to a new directory
+2. Edit `preset.yml` with your preset's metadata
+3. Add or replace templates in `templates/`
+4. Test locally with `specify preset add --dev .`
+5. Verify with `specify preset resolve spec-template`
+
+## Environment Variables
+
+| Variable | Description |
+|----------|-------------|
+| `SPECKIT_PRESET_CATALOG_URL` | Override the catalog URL (replaces all defaults) |

+
+## Future Considerations
+
+The following enhancements are under consideration for future releases:
+
+- **Composition strategies** — Allow presets to declare a `strategy` per template instead of the default `replace`:
+
+  | Type | `replace` | `prepend` | `append` | `wrap` |
+  |------|-----------|-----------|----------|--------|
+  | **template** | ✓ (default) | ✓ | ✓ | ✓ |
+  | **command** | ✓ (default) | ✓ | ✓ | ✓ |
+  | **script** | ✓ (default) | — | — | ✓ |
+
+  For artifacts and commands (which are LLM directives), `wrap` would inject preset content before and after the core template using a `{CORE_TEMPLATE}` placeholder. For scripts, `wrap` would run custom logic before/after the core script via a `$CORE_SCRIPT` variable.
+- **Script overrides** — Enable presets to provide alternative versions of core scripts (e.g. `create-new-feature.sh`) for workflow customization. A `strategy: "wrap"` option could allow presets to run custom logic before/after the core script without fully replacing it.

+# My Preset
+
+A custom preset for Spec Kit. Copy this directory and customize it to create your own.
+
+## Templates Included
+
+| Template | Type | Description |
+|----------|------|-------------|
+| `spec-template` | template | Custom feature specification template (overrides core and extensions) |
+| `myext-template` | template | Override of the myext extension's report template |
+| `speckit.specify` | command | Custom specification command (overrides core) |
+| `speckit.myext.myextcmd` | command | Override of the myext extension's myextcmd command |
+
+## Development
+
+1. Copy this directory: `cp -r presets/scaffold my-preset`
+2. Edit `preset.yml` — set your preset's ID, name, description, and templates
+3. Add or modify templates in `templates/`
+4. Test locally: `specify preset add --dev ./my-preset`
+5. Verify resolution: `specify preset resolve spec-template`
+6. Remove when done testing: `specify preset remove my-preset`
+
+## Manifest Reference (`preset.yml`)
+
+Required fields:
+- `schema_version` — always `"1.0"`
+- `preset.id` — lowercase alphanumeric with hyphens
+- `preset.name` — human-readable name
+- `preset.version` — semantic version (e.g. `1.0.0`)
+- `preset.description` — brief description
+- `requires.speckit_version` — version constraint (e.g. `>=0.1.0`)
+- `provides.templates` — list of templates with `type`, `name`, and `file`
+
+## Template Types
+
+- **template** — Document scaffolds (spec-template.md, plan-template.md, tasks-template.md, etc.)
+- **command** — AI agent workflow prompts (e.g. speckit.specify, speckit.plan)
+- **script** — Custom scripts (reserved for future use)

+You are following a customized version of the myext extension's myextcmd command.
+
+When executing this command:
+
+1. Read the user's input from $ARGUMENTS
+2. Follow the standard myextcmd workflow
+3. Additionally, apply the following customizations from this preset:
+   - Add compliance checks before proceeding
+   - Include audit trail entries in the output
+

+# Testing Extension Hooks
+
+This directory contains a mock project to verify that LLM agents correctly identify and execute hook commands defined in `.specify/extensions.yml`.
+
+## Test 1: Testing `before_tasks` and `after_tasks`
+
+1. Open a chat with an LLM (like GitHub Copilot) in this project.
+2. Ask it to generate tasks for the current directory:
+   > "Please follow `/speckit.tasks` for the `./tests/hooks` directory."
+3. **Expected Behavior**: 
+   - Before doing any generation, the LLM should notice the `AUTOMATIC Pre-Hook` in `.specify/extensions.yml` under `before_tasks`.
+   - It should state it is executing `EXECUTE_COMMAND: pre_tasks_test`.
+   - It should then proceed to read the `.md` docs and produce a `tasks.md`.
+   - After generation, it should output the optional `after_tasks` hook (`post_tasks_test`) block, asking if you want to run it.
+
+## Test 2: Testing `before_implement` and `after_implement`
+
+*(Requires `tasks.md` from Test 1 to exist)*
+
+1. In the same (or new) chat, ask the LLM to implement the tasks:
+   > "Please follow `/speckit.implement` for the `./tests/hooks` directory."
+2. **Expected Behavior**:
+   - The LLM should first check for `before_implement` hooks.
+   - It should state it is executing `EXECUTE_COMMAND: pre_implement_test` BEFORE doing any actual task execution.
+   - It should evaluate the checklists and execute the code writing tasks.
+   - Upon completion, it should output the optional `after_implement` hook (`post_implement_test`) block.
+
+## How it works
+
+The templates for these commands in `templates/commands/tasks.md` and `templates/commands/implement.md` contains strict ordered lists. The new `before_*` hooks are explicitly formulated in a **Pre-Execution Checks** section prior to the outline to ensure they're evaluated first without breaking template step numbers.
