* feat(presets): pluggable preset system with template/command overrides, catalog, and resolver

- Rename 'template packs' to 'presets' to avoid naming collision with core templates
- PresetManifest, PresetRegistry, PresetManager, PresetCatalog, PresetResolver in presets.py
- Extract CommandRegistrar to agents.py as shared infrastructure
- CLI: specify preset list/add/remove/search/resolve/info
- CLI: specify preset catalog list/add/remove
- --preset option on specify init
- Priority-based preset stacking (--priority, lower = higher precedence)
- Command overrides registered into all detected agent directories (17+ agents)
- Extension command safety: skip registration if target extension not installed
- Multi-catalog support: env var, project config, user config, built-in defaults
- resolve_template() / Resolve-Template in bash/PowerShell scripts
- Self-test preset: overrides all 6 core templates + 1 command
- Scaffold with 4 examples: core/extension template and command overrides
- Preset catalog (catalog.json, catalog.community.json)
- Documentation: README.md, ARCHITECTURE.md, PUBLISHING.md
- 110 preset tests, 253 total tests passing

* feat(presets): propagate command overrides to skills via init-options

- Add save_init_options() / load_init_options() helpers that persist
  CLI flags from 'specify init' to .specify/init-options.json
- PresetManager._register_skills() overwrites SKILL.md files when
  --ai-skills was used during init and corresponding skill dirs exist
- PresetManager._unregister_skills() restores core template content
  on preset removal
- registered_skills stored in preset registry metadata
- 8 new tests covering skill override, skip conditions, and restore

* fix: address PR check failures (ruff F541, CodeQL URL substring)

- Remove extraneous f-prefix from two f-strings without placeholders
- Replace substring URL check in test with startswith/endswith assertions
  to satisfy CodeQL incomplete URL substring sanitization rule

* fix: address Copilot PR review comments

- Move save_init_options() before preset install so skills propagation
  works during 'specify init --preset --ai-skills'
- Clean up downloaded ZIP after successful preset install during init
- Validate --from URL scheme (require HTTPS, HTTP only for localhost)
- Expose unregister_commands() on extensions.py CommandRegistrar wrapper
  instead of reaching into private _registrar field
- Use _get_merged_packs() for search() and get_pack_info() so all
  active catalogs are searched, not just the highest-priority one
- Fix fetch_catalog() cache to verify cached URL matches current URL
- Fix PresetResolver: script resolution uses .sh extension, consistent
  file extensions throughout resolve(), and resolve_with_source()
  delegates to resolve() to honor template_type parameter
- Fix bash common.sh: fall through to directory scan when python3
  returns empty preset list
- Fix PowerShell Resolve-Template: filter out dot-folders and sort
  extensions deterministically

* fix: narrow empty except blocks and add explanatory comments

* fix: address Copilot PR review comments (round 2)

- Fix init --preset error masking: distinguish "not found" from real errors
- Fix bash resolve_template: skip hidden dirs in extensions (match Python/PS)
- Fix temp dir leaks in tests: use temp_dir fixture instead of mkdtemp
- Fix self-test catalog entry: add note that it's local-only (no download_url)
- Fix Windows path issue in resolve_with_source: use Path.relative_to()
- Fix skill restore path: use project's .specify/templates/commands/ not source tree
- Add encoding="utf-8" to all file read/write in agents.py
- Update test to set up core command templates for skill restoration

* fix: remove self-test from catalog.json (local-only preset)

* fix: address Copilot PR review comments (round 3)

- 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

* fix: correct PresetError docstring from template to preset

* Removed CHANGELOG requirement

* Applying review recommendations

* Applying review recommendations

+# 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+.

+## [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
+
+- **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.

+
+
+## [0.1.10] - 2026-03-02
+
+### Fixed
+
+- **Version Sync Issue (#1721)**: Fixed version mismatch between `pyproject.toml` and git release tags
+  - Split release process into two workflows: `release-trigger.yml` for version management and `release.yml` for artifact building
+  - Version bump now happens BEFORE tag creation, ensuring tags point to commits with correct version
+  - Supports both manual version specification and auto-increment (patch version)
+  - Git tags now accurately reflect the version in `pyproject.toml` at that commit
+  - Prevents confusion when installing from source
+
+## [0.1.9] - 2026-02-28

+- **[Greenfield .NET CLI tool](https://github.com/mnriem/spec-kit-dotnet-cli-demo)** — Builds a Timezone Utility as a .NET single-binary CLI tool from a blank directory, covering the full spec-kit workflow: constitution, specify, plan, tasks, and multi-pass implement using GitHub Copilot agents.
+
+- **[Greenfield Spring Boot + React platform](https://github.com/mnriem/spec-kit-spring-react-demo)** — Builds an LLM performance analytics platform (REST API, graphs, iteration tracking) from scratch using Spring Boot, embedded React, PostgreSQL, and Docker Compose, with a clarify step and a cross-artifact consistency analysis pass included.
+
+- **[Brownfield ASP.NET CMS extension](https://github.com/mnriem/spec-kit-aspnet-brownfield-demo)** — Extends an existing open-source .NET CMS (CarrotCakeCMS-Core, ~307,000 lines of C#, Razor, SQL, JavaScript, and config files) with two new features — cross-platform Docker Compose infrastructure and a token-authenticated headless REST API — demonstrating how spec-kit fits into existing codebases without prior specs or a constitution.
+
+- **[Brownfield Java runtime extension](https://github.com/mnriem/spec-kit-java-brownfield-demo)** — Extends an existing open-source Jakarta EE runtime (Piranha, ~420,000 lines of Java, XML, JSP, HTML, and config files across 180 Maven modules) with a password-protected Server Admin Console, demonstrating spec-kit on a large multi-module Java project with no prior specs or constitution.

+- 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/`).

-## Available Extensions
+## 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 Discovery & Catalog
 
-### 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
 
-Organizations can host private catalogs:
+Spec Kit supports a **catalog stack** — an ordered list of catalogs that the CLI merges and searches across. This allows organizations to maintain their own org-approved extensions alongside an internal catalog and community discovery, all at once.
 
-```bash
-# Add custom catalog
-specify extension add-catalog https://internal.company.com/spec-kit/catalog.json
+#### Catalog Stack Resolution
 
-# Set as default
-specify extension set-catalog --default https://internal.company.com/spec-kit/catalog.json
+The active catalog stack is resolved in this order (first match wins):
 
-# List catalogs
-specify extension catalogs
+1. **`SPECKIT_CATALOG_URL` environment variable** — single catalog replacing all defaults (backward compat)
+2. **Project-level `.specify/extension-catalogs.yml`** — full control for the project
+3. **User-level `~/.specify/extension-catalogs.yml`** — personal defaults
+4. **Built-in default stack** — `catalog.json` (install_allowed: true) + `catalog.community.json` (install_allowed: false)
+
+#### Default Built-in Stack
+
+When no config file exists, the CLI uses:
+
+| Priority | Catalog | install_allowed | Purpose |
+|----------|---------|-----------------|---------|
+| 1 | `catalog.json` (default) | `true` | Curated extensions available for installation |
+| 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

+  - name: "community"

+    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
+```

-## Open Questions
+## Resolved Questions
 
-### 1. Extension Namespace
+The following questions from the original RFC have been resolved during implementation:
+
+### 1. Extension Namespace ✅ RESOLVED
 
 **Question**: Should extension commands use namespace prefix?
 
-**Options**:
+**Decision**: **Option C** - Both prefixed and aliases are supported. Commands use `speckit.{extension}.{command}` as canonical name, with optional aliases defined in manifest.
 
-- A) Prefixed: `/speckit.jira.specstoissues` (explicit, avoids conflicts)
-- B) Short alias: `/jira.specstoissues` (shorter, less verbose)
-- C) Both: Register both names, prefer prefixed in docs
-
-**Recommendation**: C (both), prefixed is canonical
+**Implementation**: The `aliases` field in `extension.yml` allows extensions to register additional command names.
 
 ---
 
-### 2. Config File Location
+### 2. Config File Location ✅ RESOLVED
 
 **Question**: Where should extension configs live?
 
-**Options**:
+**Decision**: **Option A** - Extension directory (`.specify/extensions/{ext-id}/{ext-id}-config.yml`). This keeps extensions self-contained and easier to manage.
 
-- A) Extension directory: `.specify/extensions/jira/jira-config.yml` (encapsulated)
-- B) Root level: `.specify/jira-config.yml` (more visible)
-- C) Unified: `.specify/extensions.yml` (all extension configs in one file)
-
-**Recommendation**: A (extension directory), cleaner separation
+**Implementation**: Each extension has its own config file within its directory, with layered resolution (defaults → project → local → env vars).
 
 ---
 
-### 3. Command File Format
+### 3. Command File Format ✅ RESOLVED
 
 **Question**: Should extensions use universal format or agent-specific?
 
-**Options**:
+**Decision**: **Option A** - Universal Markdown format. Extensions write commands once, CLI converts to agent-specific format during registration.
 
-- A) Universal Markdown: Extensions write once, CLI converts per-agent
-- B) Agent-specific: Extensions provide separate files for each agent
-- C) Hybrid: Universal default, agent-specific overrides
-
-**Recommendation**: A (universal), reduces duplication
+**Implementation**: `CommandRegistrar` class handles conversion to 15+ agent formats (Claude, Copilot, Gemini, Cursor, etc.).
 
 ---
 
-### 4. Hook Execution Model
+### 4. Hook Execution Model ✅ RESOLVED
 
 **Question**: How should hooks execute?
 
-**Options**:
+**Decision**: **Option A** - Hooks are registered in `.specify/extensions.yml` and executed by the AI agent when it sees the hook trigger. Hook state (enabled/disabled) is managed per-extension.
 
-- A) AI agent interprets: Core commands output `EXECUTE_COMMAND: name`
-- B) CLI executes: Core commands call `specify extension hook after_tasks`
-- C) Agent built-in: Extension system built into AI agent (Claude SDK)
-
-**Recommendation**: A initially (simpler), move to C long-term
+**Implementation**: `HookExecutor` class manages hook registration and state in `extensions.yml`.
 
 ---
 
-### 5. Extension Distribution
+### 5. Extension Distribution ✅ RESOLVED
 
 **Question**: How should extensions be packaged?
 
-**Options**:
+**Decision**: **Option A** - ZIP archives downloaded from GitHub releases (via catalog `download_url`). Local development uses `--dev` flag with directory path.
 
-- A) ZIP archives: Downloaded from GitHub releases
-- B) Git repos: Cloned directly (`git clone`)
-- C) Python packages: Installable via `uv tool install`
-
-**Recommendation**: A (ZIP), simpler for non-Python extensions in future
+**Implementation**: `ExtensionManager.install_from_zip()` handles ZIP extraction and validation.
 
 ---
 
-### 6. Multi-Version Support
+### 6. Multi-Version Support ✅ RESOLVED
 
 **Question**: Can multiple versions of same extension coexist?
 
+**Decision**: **Option A** - Single version only. Updates replace the existing version with atomic rollback on failure.
+
+**Implementation**: `extension update` performs atomic backup/restore to ensure safe updates.
+
+---
+
+## Open Questions (Remaining)
+
+### 1. Sandboxing / Permissions (Future)
+
+**Question**: Should extensions declare required permissions?
+
 **Options**:
 
-- A) Single version: Only one version installed at a time
-- B) Multi-version: Side-by-side versions (`.specify/extensions/jira@1.0/`, `.specify/extensions/jira@2.0/`)
-- C) Per-branch: Different branches use different versions
+- A) No sandboxing (current): Extensions run with same privileges as AI agent
+- B) Permission declarations: Extensions declare `filesystem:read`, `network:external`, etc.
+- C) Opt-in sandboxing: Organizations can enable permission enforcement
 
-**Recommendation**: A initially (simpler), consider B in future if needed
+**Status**: Deferred to future version. Currently using trust-based model where users trust extension authors.
+
+---
+
+### 2. Package Signatures (Future)
+
+**Question**: Should extensions be cryptographically signed?
+
+**Options**:
+
+- A) No signatures (current): Trust based on catalog source
+- B) GPG/Sigstore signatures: Verify package integrity
+- C) Catalog-level verification: Catalog maintainers verify packages
+
+**Status**: Deferred to future version. `checksum` field is available in catalog schema but not enforced.

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

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

+# 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?}

+
+### 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.

+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.
+

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

+2. **Create the feature branch** by running the script with `--short-name` (and `--json`), and do NOT pass `--number` (the script auto-detects the next globally available number across all branches and spec directories):
 
-   a. First, fetch all remote branches to ensure we have the latest information:
-
-      ```bash
-      git fetch --all --prune
-      ```
-
-   b. Find the highest feature number across all sources for the short-name:
-      - Remote branches: `git ls-remote --heads origin | grep -E 'refs/heads/[0-9]+-<short-name>$'`
-      - Local branches: `git branch | grep -E '^[* ]*[0-9]+-<short-name>$'`
-      - Specs directories: Check for directories matching `specs/[0-9]+-<short-name>`
-
-   c. Determine the next available number:
-      - Extract all numbers from all three sources
-      - Find the highest number N
-      - Use N+1 for the new branch number
-
-   d. Run the script `{SCRIPT}` with the calculated number and short-name:
-      - Pass `--number N+1` and `--short-name "your-short-name"` along with the feature description
-      - Bash example: `{SCRIPT} --json --number 5 --short-name "user-auth" "Add user authentication"`

+   - PowerShell example: `{SCRIPT} -Json -ShortName "user-auth" "Add user authentication"`
 
    **IMPORTANT**:
-   - Check all three sources (remote branches, local branches, specs directories) to find the highest number
-   - Only match branches/directories with the exact short-name pattern
-   - If no existing branches/directories found with this short-name, start with number 1
+   - 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 is provided in the terminal as output - always refer to it to get the actual content you're looking for

+# 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.
