What problem does it solve? AI agents that delegate work to sub-agents lack a centralized catalog of installed skills and their rules, forcing sub-agents to rediscover conventions on every run. This Skill builds a single registry file with pre-digested compact rules that delegators inject directly into sub-agent prompts. ## Core Features & Use Cases - Skill Scanning: Discovers SKILL.md files across user-level and project-level directories for Claude Code, OpenCode, Gemini CLI, Cursor, VS Code Copilot, and Antigravity, with deduplication and exclusion of SDD workflow skills. - Compact Rules Generation: Distills each skill into 5-15 actionable rules that sub-agents can apply without reading full SKILL.md files. - Convention Indexing: Scans project convention files (AGENTS.md, CLAUDE.md, .cursorrules, GEMINI.md) and extracts all referenced paths so sub-agents need zero extra hops. - Use Case: After installing new skills in a project, run this Skill to regenerate .atl/skill-registry.md so the orchestrator passes accurate, pre-resolved rules to every sub-agent it launches. ## Quick Start Ask the agent to update the skill registry for the current project so it scans installed skills and writes the registry to .atl/skill-registry.md.
