What problem does it solve? After installing, removing, or renaming skills, AI agents and delegators 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 delegation decisions always use current information. ## Core Features & Use Cases - Skill Scanning: Scans all known user-level and project-level skill directories for SKILL.md files and extracts name and trigger descriptions from frontmatter. - Registry Generation: Writes a deduplicated registry to .atl/skill-registry.md, preferring project-level skills over global ones and skipping internal skills like sdd-* and _shared. - Persistence & Caching: Saves the registry to Engram with topic_key skill-registry when available, and reports cache hit or regeneration status. - Use Case: After adding a new code-review skill to your project, run this Skill so delegating agents immediately see the new skill's trigger and exact SKILL.md path. ## Quick Start Update the skill registry to index all current skills after my recent skill changes.
