wtf is skill-router?

skill-router is a meta-skill for Claude Code, which is Anthropic's command line coding assistant. In Claude Code you can install separate skills, each one a small Markdown file that gives the assistant extra know-how for a particular task such as writing tests, doing SEO audits, or handling deployments. People who collect many skills can end up with dozens or even hundreds installed, and then forget which one fits the current question. The router is meant to solve that. When activated, it scans every installed skill once per session, builds a lightweight index, and then watches incoming requests. If the request is a simple question it answers directly with no skill loaded. If the request clearly matches one skill in the index it either suggests that skill and asks before loading, or routes silently and just appends a small attribution like "(via skill-name)" to the answer. Only one skill is used per request, and weak or ambiguous matches are ignored to avoid noise. Installation is a single command that downloads the SKILL.md file into the user's Claude skills folder. The README lists four commands: /skill-router on for suggest mode, /skill-router on --auto for silent routing, /skill-router status to see what is indexed, and /skill-router stats to see which skills get used. Usage counts are stored in a JSON file under ~/.claude so you can later spot skills you never use and remove them. The author notes the index is session-only and may reset under context compression in very long sessions. The license is MIT.
