skills/ROUTER.md is the master entry point. Read it first — it maps any user prompt to the right skill(s) via a decision tree, quick routing table, and power combos for multi-skill tasks.

Each skill lives in its own SKILL.md. Read the router → identify the relevant skill(s) → load those files before responding. Skills are composable — the router lists common multi-skill combinations for complex tasks.

Each category folder contains a README.md summarising the skills inside, when to use each, and useful combos. Skim these for orientation before diving into individual skills.
