Skill Usage Stats

Analyze Claude Code session history to show skill usage statistics and help clean up unused skills.

Step 1: Run the analyzer

python3 ~/.claude/skills/skill-usage-stats/analyze.py

Print the output as-is.

Step 2: Suggest deletion candidates

From the "never used" list, identify candidates using these criteria:

• Unrelated to the user's current work environment
• Duplicates — multiple skills with overlapping functionality
• Names that clearly suggest no practical use case

For each candidate, show the skill name and a short one-line reason for deletion.

Step 3: Delete confirmed skills

Once the user confirms which skills to delete, run:

python3 ~/.claude/skills/skill-usage-stats/analyze.py --delete skill1 skill2 ...

This handles everything automatically — both local skills (~/.claude/skills/) and plugins (installed_plugins.json entry removal + cache directory deletion). Print the output as-is.
