* docs: Document dual-catalog system for extensions

- Clarify distinction between catalog.json (curated) and catalog.community.json (reference)
- Update EXTENSION-DEVELOPMENT-GUIDE.md to explain community catalog submission
- Update EXTENSION-PUBLISHING-GUIDE.md with dual-catalog workflow
- Update EXTENSION-USER-GUIDE.md with catalog selection guidance
- Expand README.md with comprehensive catalog explanation
- Update RFC-EXTENSION-SYSTEM.md with dual-catalog design and current implementation
- Change GitHub references from statsperform to github
- Add SPECKIT_CATALOG_URL environment variable documentation

This clarifies how organizations can curate their own catalog while
browsing community-contributed extensions for discovery.

# Spec Kit Community Extensions
# Spec Kit Extensions
Community-contributed extensions for [Spec Kit](https://github.com/github/spec-kit).
Extension system for [Spec Kit](https://github.com/github/spec-kit) - add new functionality without bloating the core framework.
## 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):

## Adding Your Extension
See the [Extension Publishing Guide](EXTENSION-PUBLISHING-GUIDE.md) for instructions on how to submit your extension to the community catalog.
### 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
```
