What problem does it solve? Teams building Claude Code skills have no visibility into which skills are actually used, how often they succeed, or which ones fail. This Skill installs tracking hooks that automatically measure skill usage so you can make data-driven decisions about your skill library. ## Core Features & Use Cases - Automatic Hook Installation: Writes bash hook scripts for UserPromptSubmit, PreToolUse, and PostToolUse events and registers them in .claude/settings.json. - Usage Logging: Captures prompt submissions, skill activations (via SKILL.md reads), and verification results into JSONL activity logs. - Usage Analysis: Generates reports showing invocations, success/failure rates per skill, unused skills, and high-failure-rate skills. - Use Case: After rolling out a set of custom skills to your team, run the analysis script to discover that one procedural skill has a 60% failure rate and three skills are never invoked, then prioritize fixes accordingly. ## Quick Start Set up skill usage tracking in this project by running the setup script and then verifying the installation.
