2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 10 stars10 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Use when organizing a large local skill library into category router skills, refreshing a compact skill inventory, or deciding which leaf skill bodies need to be read before agent classification.

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.
