gentle-ai-skill-registry

## 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. ## References - `docs/skill-style-guide.md` — how skills should be authored before indexing. - `skills/_shared/skill-resolver.md` — how delegators use the index.
