Quratulain-bilal 4a465431b8 fix: use missing_ok for temp file cleanup to avoid masking errors (#3803)
* fix(agent-context): recurse for nested plans in Python mtime fallback

The Python port's mtime fallback discovered plans with a one-level
specs/*/plan.md glob, so a scoped layout created via
SPECIFY_FEATURE_DIRECTORY (specs/<scope>/<feature>/plan.md) was missed when
feature.json is absent — the fallback returned no plan and the managed
context section omitted the 'at <plan>' line. The bash and PowerShell twins
were already fixed to recurse (#3024); the Python twin was left behind.

Switch to specs.rglob('plan.md') with the same symlink-safe containment check
the bash twin uses (resolve each candidate and confirm it stays within the
project root before ranking by mtime), so a plan reached through a specs/
symlink pointing outside the project is not selected.

Adds parity regression tests (vs bash and vs PowerShell) covering a nested
specs/<scope>/<feature>/plan.md; both fail on the pre-fix one-level glob.

Fixes #3733

* test(agent-context): cover symlink containment in the mtime fallback

The recursive fallback resolves each candidate before the relative_to()
containment check, but nothing exercised that path. Add a parity test for a
plan reachable only through a specs/ symlink pointing outside the project:
relative_to() is lexical and would accept it, emitting an in-project-looking
path for an out-of-project file. Both the bash twin and the Python port skip
it, so the "at <plan>" line is omitted.

Also correct the module docstring, which still described the fallback as
scanning specs/*/plan.md one level deep.

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.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:

# 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:

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:

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:

  1. Prepare your extension following the Extension Development Guide
  2. Create a GitHub release for your extension
  3. File an issue using the Extension Submission template with all required metadata
  4. 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.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:

# 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
