What problem does it solve? After installing, removing, or renaming skills, agents lose track of what skills exist and where they live, causing blind searches and stale references. This Skill rebuilds a fresh index of all available skills so delegators always have an accurate map. ## Core Features & Use Cases - Skill Indexing: Scans user and project skill directories for SKILL.md files and records each skill's name, trigger description, scope, and exact path. - Deduplication Rules: Prefers project-level skills over global ones and skips internal entries like sdd-*, _shared, and itself. - Persistent Registry: Always writes .atl/skill-registry.md and optionally persists the index to Engram under the topic key skill-registry. - Use Case: After adding a new skill to your project, run this Skill so delegating agents receive exact SKILL.md paths instead of guessing which skills exist. ## Quick Start Update the skill registry to reindex all available skills after my recent skill changes.
