Eric Rodriguez Suazo 793632089a fix(forge): use hyphen notation for command refs in Forge integration (#2462)
* fix(forge): use hyphen notation for command refs in Forge integration

- Add invoke_separator = "-" class attribute to ForgeIntegration so
  effective_invoke_separator() returns "-" for shared-template installs
- Add "invoke_separator": "-" to ForgeIntegration.registrar_config so
  agents.py CommandRegistrar can resolve refs with the correct separator
- Pass invoke_separator to process_template() in ForgeIntegration.setup()
  so all .forge/commands/*.md bodies use /speckit-foo notation
- Replace literal /speckit.specify with __SPECKIT_COMMAND_SPECIFY__ in
  extensions/git/commands/speckit.git.feature.md so every agent resolves
  the reference through its own separator
- Apply resolve_command_refs re.sub in agents.py register_commands() after
  argument-placeholder substitution so extension commands registered for
  Forge get /speckit-foo refs; all other agents continue to get /speckit.foo

Fixes ZSH compatibility: dot-notation command invocations (/speckit.specify)
are misinterpreted by ZSH as file-path operations; hyphen notation
(/speckit-specify) works correctly in all shells.

* fix(agents): propagate invoke_separator from integration class into AGENT_CONFIGS

Skills-based agents (claude, codex, kimi, …) inherit invoke_separator="-"
from SkillsIntegration but do not repeat it in their registrar_config dicts.
_build_agent_configs() was copying registrar_config verbatim, so
register_commands() fell back to "." when resolving __SPECKIT_COMMAND_*__
tokens for those agents — emitting /speckit.specify instead of the correct
/speckit-specify for extension commands like speckit.git.feature.

Fix: after copying registrar_config, inject invoke_separator from the
integration's class attribute when it is not already declared explicitly.
This makes the integration class the single source of truth for all agents,
without requiring each SkillsIntegration subclass to duplicate the field.

Also replace the inline re.sub in register_commands() with a call to
IntegrationBase.resolve_command_refs() (deferred import to avoid the
existing circular dependency) so token-resolution logic is not duplicated.

Adds two tests in test_agent_config_consistency.py:
- test_skills_agents_have_hyphen_invoke_separator_in_agent_configs: asserts
  every /SKILL.md agent has invoke_separator="-" in AGENT_CONFIGS.
- test_skills_agent_command_token_resolves_with_hyphen: end-to-end check via
  CommandRegistrar that the git extension's speckit.git.feature command is
  installed for Claude with /speckit-specify (not /speckit.specify).

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 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:

  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
