* feat(extensions): per-event hook lists with priority ordering The manifest validator restricted each hook event to a single mapping, even though HookExecutor stores entries as a list per event. This blocked an extension from running multiple commands on one event (e.g. a verification step plus a doc-generation step after speckit.plan), and get_hooks_for_event returned entries in raw insertion order with no way to influence execution order across or within extensions. This change: 1. Validator: accept hooks.<event> as either a single mapping or a list of mappings. Each entry is validated individually and may carry an optional integer `priority` (>= 1, default 10; bool rejected). 2. Command-ref normalization: apply rename / alias->canonical rewriting to every entry in the list, not just the head. 3. register_hooks: expand list entries, persist `priority`, and purge-and-replace all entries owned by the extension on each event so a reinstall whose shape changed (single<->list, or a shorter list) leaves no orphaned entries behind. 4. get_hooks_for_event: sort enabled entries by `priority` ascending with a stable sort (ties keep insertion order). The existing normalize_priority helper is reused as the sort key so corrupted on-disk values fall back to the default instead of raising. Backward compatible: existing single-mapping manifests parse and register unchanged with priority defaulting to 10. The extension-level `priority` used by preset/template resolution is independent of the new hook-entry `priority`. Implements #2378 * fix(extensions): harden register_hooks per PR review - Skip non-dict hook entries before .get() so a manifest that bypasses validation can't crash register_hooks with AttributeError. - Normalize `priority` on save via normalize_priority so the on-disk config stays clean, mirroring the read-side defense in get_hooks_for_event. - Tests: cover the non-dict-entry skip and add encoding="utf-8" to the new tests' manifest writes. * fix(extensions): purge dropped-event hook orphans on reinstall register_hooks only purged events the new manifest still declared, so an extension that dropped an event on reinstall left stale entries for it in the project config. Purge this extension's entries from undeclared events (and prune emptied events) before registering; scoped to this extension, and a no-op for the install/update flow where unregister_hooks runs first. * fix(extensions): reject boolean priority and complete orphan purge - normalize_priority falls back to default for bool values - dedup deletes duplicate commands before re-insert for last-wins ties - register_hooks purges orphans even when all hooks are dropped * docs(extensions): document per-event hook lists and priority - EXTENSION-API-REFERENCE: hook event accepts a mapping or list; add priority field reference and last-wins dedup note - EXTENSION-DEVELOPMENT-GUIDE: add list-form example with priority * docs(extensions): show both single and list hook forms in schema snippet * docs(extensions): reference DEFAULT_HOOK_PRIORITY in normalize_priority normalize_priority hard-coded the default as the literal 10 in both its signature and docstring, duplicating DEFAULT_HOOK_PRIORITY. Reference the constant in the signature and drop the literal from the docstring so the default has a single source of truth.
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. Maintainers only verify that catalog entries are complete and correctly formatted — 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 issue template
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. Maintainers only verify that catalog entries are complete and correctly formatted — 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 page 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
- File an issue using the Extension Submission template with all required metadata
- Wait for review — a maintainer will review the submission, update the catalog, and close the issue
See the Extension Publishing Guide for detailed step-by-step instructions.
Submission Checklist
Before submitting, ensure:
- ✅ Valid
extension.ymlmanifest - ✅ 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:
# 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 <extension-name> --from https://github.com/<org>/<repo>/archive/refs/tags/<version>.zip
# List installed extensions
specify extension list
