* catalog: add wireframe extension Adds https://github.com/TortoiseWolfe/spec-kit-extension-wireframe (v0.1.0) to the community catalog. Provides a visual feedback loop for spec-driven development: SVG wireframe generation, review, and sign-off. Approved wireframes become spec constraints honored by /plan, /tasks, and /implement. Supersedes #1410 — the old PR predated the extension system introduced in #2130 and proposed commands in templates/commands/, which is no longer the right home for third-party commands. * catalog: address review feedback (position + author) Two changes per Copilot review: - Move `wireframe` entry alphabetically between `whatif` and `worktree` (was appended after `worktrees`). - Simplify `author` from "TortoiseWolfe (turtlewolfe.com)" to just "TortoiseWolfe" so the exact-match author filter in `ExtensionCatalog.search` finds the entry. Portfolio URL remains accessible via `homepage`/`repository`. Thanks @Copilot, @mnriem for the review. * docs(readme): add Wireframe Visual Feedback Loop row Addresses @mnriem's follow-up: the README extension table also needs an entry, not just the catalog JSON. Slots in alphabetically between "What-if Analysis" and "Worktree Isolation" with category `visibility` and Read+Write effect (since sign-off writes the approved wireframe paths into spec.md). * catalog: use speckit-prefixed command names in wireframe description Address remaining Copilot review comment on PR #2262. The actual commands are /speckit.plan, /speckit.tasks, /speckit.implement; the unprefixed names would mislead catalog users. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * catalog: bump wireframe extension to v0.1.1 v0.1.1 of spec-kit-extension-wireframe ships the /speckit.-prefixed command references in extension.yml and README.md. This updates the catalog entry to point at the new release tag so `specify extension add wireframe` installs the corrected version. * catalog: set wireframe created_at to current timestamp Per EXTENSION-PUBLISHING-GUIDE.md: newly added entries should use the current timestamp for both created_at and updated_at. The 04-17 value reflected when I drafted the entry locally, not when the catalog submission landed. --------- Co-authored-by: TortoiseWolfe <jonpohlner@gmail.com> Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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
