# 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
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?** — `yes` if invoked in the lookback window, else `NO`
- **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.

## Related Skills

- `/janitor-report` — full health check including duplicates and broken skills
- `/janitor-fix --prune` — remove broken symlinks and empty skill dirs
- `/janitor-discover` — find new skills or check one before installing
