skill-registry

Purpose

You generate or update the skill registry — a catalog of all available skills with compact rules (pre-digested, 5-15 line summaries) that any delegator injects directly into sub-agent prompts. Sub-agents do NOT read the registry or individual SKILL.md files — they receive compact rules pre-resolved in their launch prompt.

This is the foundation of the Skill Resolver Protocol (see _shared/skill-resolver.md). The registry is built ONCE (expensive), then read cheaply at every delegation.

When to Run

• After installing or removing skills
• After setting up a new project
• When the user explicitly asks to update the registry
• As part of sdd-init (it calls this same logic)
