Skill Router

Skill Router

Use this skill to organize many local skills without loading every leaf skill body into the model context. The script builds a compact inventory, marks ambiguous or duplicate-description skills for body review, and lets the agent author the final routing plan.

Check First

• Confirm the workspace has skill-router.config.json, or set SKILL_ROUTER_LEAF_ROOTS, SKILL_ROUTER_EXPOSED_ROOT, and SKILL_ROUTER_ROUTING_ROOT.
• Keep hidden leaf skills separate from exposed category router skills.
• Treat BM25 and token-overlap similarity as read-priority hints only.
• Read leaf SKILL.md bodies only when routing-review.md marks them under Needs Body Review, the compact metadata is ambiguous, or a category boundary would change.

Workflow

1. Run node scripts/skill-router.mjs scan.
2. Read routing-review.md, skill-inventory.json, and the current routing-index.json from the configured routing root.
3. Reuse existing categories when their use_when and avoid_when boundaries stay clear.
4. Create a new category only when existing categories would need mismatched special cases or vague avoidance rules.
5. Write routing-plan.json with all categories and routes.
6. Run node scripts/skill-router.mjs apply, then scan, then validate.

Stop When

• The same directory is both the hidden leaf root and exposed category root.
• A catch-all category such as misc, general, or other would be required.
• Classification would be based on keywords instead of workflow force and agent behavior.
