* fix: allow Claude to chain skills for hook execution (#2178) - Set disable-model-invocation to false so Claude can invoke extension skills (e.g. speckit-git-feature) from within workflow skills - Inject dot-to-hyphen normalization note into Claude SKILL.md hook sections so the model maps extension.yml command names to skill names - Replace Unicode checkmark with ASCII [OK] in auto-commit scripts to fix PowerShell encoding errors on Windows - Move Claude-specific frontmatter injection to ClaudeIntegration via post_process_skill_content() hook on SkillsIntegration, wired through presets and extensions managers - Add positive and negative tests for all changes Fixes #2178 * refactor: address PR review feedback - Preserve line-ending style (CRLF/LF) in _inject_hook_command_note instead of always inserting \n, matching the convention used by other injection helpers in the same module. - Extract duplicated _post_process_skill() from extensions.py and presets.py into a shared post_process_skill() function in agents.py. Both modules now import and call the shared helper. * fix: match full hook instruction line in regex The regex in _inject_hook_command_note only matched lines ending immediately after 'output the following', but the actual template lines continue with 'based on its `optional` flag:'. Use [^\r\n]* to capture the rest of the line before the EOL. * refactor: use integration object directly for post_process_skill_content Instead of a free function in agents.py that re-resolves the integration by key, callers in extensions.py and presets.py now resolve the integration once via get_integration() and call integration.post_process_skill_content() directly. The base identity method lives on SkillsIntegration.
Spec Kit Extensions
Extension system for 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.jsonin the GitHub-hosted spec-kit repo - CLI Default: The
specify extensioncommands use the upstream catalog URL by default, unless overridden - Org Catalog: Point
SPECKIT_CATALOG_URLat 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:
# Override the default upstream catalog with your organization's catalog
export SPECKIT_CATALOG_URL="https://your-org.com/spec-kit/catalog.json"
specify extension search # Now uses your organization's catalog instead of the upstream default
Community Reference Catalog (catalog.community.json)
Note
Community extensions are independently created and maintained by their respective authors. GitHub and the Spec Kit maintainers may review pull requests that add entries to the community catalog for formatting, catalog structure, or policy compliance, but they do not review, audit, endorse, or support the extension code itself. Review extension source code before installation and use at your own discretion.
- Purpose: Browse available community-contributed extensions
- Status: Active - contains extensions submitted by the community
- Location:
extensions/catalog.community.json - Usage: Reference catalog for discovering available extensions
- Submission: Open to community contributions via Pull Request
How It Works:
Making Extensions Available
You control which extensions your team can discover and install:
Option 1: Curated Catalog (Recommended for Organizations)
Populate your catalog.json with approved extensions:
- Discover extensions from various sources:
- Browse
catalog.community.jsonfor community extensions - Find private/internal extensions in your organization's repos
- Discover extensions from trusted third parties
- Browse
- Review extensions and choose which ones you want to make available
- Add those extension entries to your own
catalog.json - Team members can now discover and install them:
specify extension searchshows your curated catalogspecify 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:
specify extension add <extension-name> --from https://github.com/org/spec-kit-ext/archive/refs/tags/v1.0.0.zip
Benefits: Quick for one-off testing or private extensions
Tradeoff: Extensions installed this way won't appear in specify extension search for other team members unless you also add them to your catalog.json.
Available Community Extensions
Note
Community extensions are independently created and maintained by their respective authors. GitHub and the Spec Kit maintainers may review pull requests that add entries to the community catalog for formatting, catalog structure, or policy compliance, but they do not review, audit, endorse, or support the extension code itself. The Community Extensions website is also a third-party resource. Review extension source code before installation and use at your own discretion.
🔍 Browse and search community extensions on the Community Extensions website.
See the Community Extensions section in the main README for the full list of available community-contributed extensions.
For the raw catalog data, see catalog.community.json.
Adding Your Extension
Submission Process
To add your extension to the community catalog:
- Prepare your extension following the Extension Development Guide
- Create a GitHub release for your extension
- Submit a Pull Request that:
- Adds your extension to
extensions/catalog.community.json - Updates this README with your extension in the Available Extensions table
- Adds your extension to
- Wait for review - maintainers will review and merge if criteria are met
See the Extension Publishing Guide for detailed step-by-step instructions.
