Skill Router

This skill manages dynamic skill loading for OpenClaw. It intercepts every user message, scores it against the skill index, and injects only the relevant skills (0-3) instead of the entire catalog.

Protocol

On EVERY user message, follow these steps:

  1. •

    Score the message against the skill index:

    bash
    skill-router match "<user_message>"
  2. •

    Read the context file to see matched skills:

    bash
    cat .skill-router-context.md
  3. •

    If skills matched, read their SKILL.md files for detailed guidance:

    • •The context file lists the paths to each matched skill
    • •Read each SKILL.md to understand how to use that skill
  4. •

    Proceed with the task using the matched skill guidance.

Commands

  • •skill-router build - Rebuild the skill index (run when skills are added/changed)
  • •skill-router match "<message>" - Score a message and write context
  • •skill-router status - Check index health and configuration

Configuration

Environment variables:

  • •SKILL_ROUTER_MAX_RESULTS - Max skills to return (default: 3)
  • •SKILL_ROUTER_THRESHOLD - Minimum score to include (default: 0.3)
