skill-registry

name: skill-registry description: "Trigger: update skills, skill registry, actualizar skills, after skill changes. Index available skills by trigger and path." license: MIT metadata: author: gentleman-programming version: "1.0"

Activation Contract

Use this skill after installing, removing, creating, moving, or renaming skills, or when a delegator needs a fresh skill index.

Hard Rules

• The registry is an index, not a compiler or summary. SKILL.md remains the source of truth.
• Do not generate or inject compact rules by default; preserve author intent by passing exact skill paths to subagents.
• Always write .atl/skill-registry.md regardless of SDD persistence mode.
• Save the registry to Engram as topic_key: skill-registry when available, with capture_prompt: false.
• Skip sdd-*, _shared, and skill-registry; deduplicate by skill name, preferring project-level skills over user-level skills.
• Add .atl/ to .gitignore when possible unless explicitly disabled.

Decision Gates

| Situation | Action | | --- | --- | | Same skill exists globally and in project | Keep the project-level skill | | Same skill exists in multiple global locations | Keep the first source in scan order | | No skills found | Write an empty registry so agents stop searching blindly | | Agent will delegate work | Select matching registry rows and pass their SKILL.md paths |

Execution Steps

1. Scan all known user and project skill directories for */SKILL.md.
2. Read frontmatter only as needed to extract name and description trigger text.
3. Render .atl/skill-registry.md with scanned sources, registry contract, skill name, trigger/description, scope, and exact path.
4. Persist to Engram when available using title: skill-registry, topic_key: skill-registry, type: config, and capture_prompt: false.
5. Return the registry path, skill count, cache status, and whether Engram was updated.

Output Contract

Return:

• Project name and .atl/skill-registry.md path.
• Number of indexed skills.
• Whether the cache was hit or regenerated.
• Any skipped or duplicate skills when relevant.
