Skill Value Report
Show whether each installed skill is earning the context-window tokens it costs. Combines token cost and usage tracking into a single view, sorted with the heaviest unused skills at the top.
Replaces the v1.2 split between /janitor-tokens (cost only) and /janitor-usage (usage only).
How to Run
bash ~/.claude/skills/skills-janitor/scripts/value.sh [--weeks N] [--budget N] [--json]
--weeks N— usage lookback window (default: 4)--budget N— context window size for % calculations (default: 200000)--json— emit raw JSON
Output
A table of every installed skill with:
- Tokens — approximate token count of the skill's SKILL.md
- Budget — % of the configured context window
- Used? —
yesif invoked in the lookback window, elseNO - Last Used — date of most recent invocation
Followed by a summary:
- Total tokens loaded into context
- Active vs. unused split
- Top wasters: heavy skills with zero usage
Plugin-namespaced skills appear with their full invocation name (e.g., marketing-skills:image, figma:figma-use).
When to Suggest Action
If "unused skill cost" exceeds 20% of the budget, recommend the user run /janitor-report for a full health check or (in v1.4+) /janitor-swipe to triage interactively.
