Skill Usage Statistics

View QE skill usage patterns to identify popular skills, undertriggering skills, and optimization opportunities.

Activation

/skill-stats

What It Reports

  1. Most Used Skills — Top 10 skills by invocation count
  2. Undertriggering Skills — Skills with good descriptions but low usage
  3. Never Used Skills — Skills that have never been triggered
  4. Trigger Method — How skills are activated (explicit /command vs auto-selected)
  5. Recommendations — Skills to improve, merge, or deprecate

Usage Log Format

Skill invocations are logged to ${CLAUDE_PLUGIN_DATA}/skill-usage.log:

Gotchas

  • Log file grows unbounded — rotate periodically with tail -n 1000 $LOG > $LOG.tmp && mv $LOG.tmp $LOG
  • Auto-selected skills may not always be the best match — review undertriggering skills for description improvements
  • Usage count alone doesn't indicate quality — a skill used 100x but failing 50% needs fixing, not celebrating
