janitor-value

Original：🇺🇸 English

Translated

Show whether each skill is earning its context-window cost — combined tokens-used view sorted by waste. Use when the user asks 'are my skills worth it', 'what's my context budget', 'which skills are dead weight', or wants to audit skill value, token cost, or usage. Trigger with '/janitor-value'.

Skill Value Report

Show whether each installed skill is earning the context-window tokens it costs.

Overview

Combine token cost and usage tracking into a single view of every installed skill, sorted with the heaviest unused skills at the top. The report splits each skill's cost into what is permanently loaded (the description) and what only loads on demand (the body), then cross-references recent invocations so the user can see which skills are dead weight.

Replaces the v1.2 split between

/janitor-tokens

(cost only) and

/janitor-usage

(usage only).

Prerequisites

Claude Code with the skills-janitor plugin installed (provides
```
scripts/value.sh
```
)
bash 3.2+ (the stock macOS bash works; no external dependencies)
Read access to
```
~/.claude/skills
```
,
```
~/.claude/agents
```
, and local Claude Code session history
No authentication or API keys required — the script reads local files only

Instructions

Step 1: Run the value script

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

Step 2: Present the results

Show the table and summary to the user. When explaining results, do NOT describe body tokens as permanent context cost — only descriptions are always loaded. Plugin-namespaced skills appear with their full invocation name (e.g.,

marketing-skills:image

,

figma:figma-use

).

Step 3: Suggest action when waste is high

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.

Output

A table of every installed skill with:

Always — description tokens, permanently in the system prompt (the real context rent)
Body — the rest of SKILL.md, loaded only when the skill triggers (progressive disclosure)
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 (the always-loaded TOTAL includes skills plus subagent descriptions from
```
~/.claude/agents
```
, reported as % of budget)
Active vs. unused split
Top wasters: heavy skills with zero usage

Error Handling

Error:
```
value.sh: No such file or directory
```
Solution: The plugin is installed under a different root. Locate it with
```
ls ~/.claude/skills
```
or check the plugin cache, then run the script from its actual location.
Error: Every skill shows
```
NO
```
in the Used? column Solution: The lookback window may be too short or session history is empty. Re-run with a longer window, e.g.
```
--weeks 12
```
.
Error: A skill shows 0 tokens Solution: Its SKILL.md is missing or unreadable. Run
```
/janitor-report
```
to surface broken skills, then
```
/janitor-fix --prune
```
to clean them up.
Error: Percentages look wrong for a non-default model Solution: Pass the correct context size explicitly, e.g.
```
--budget 500000
```
.

Examples

Example 1: Standard value check

Input: "Are my skills worth their token cost?"

Output: Run

bash ~/.claude/skills/skills-janitor/scripts/value.sh

, then present the table sorted by waste and the summary line, e.g. "Always-loaded total: 8,420 tokens (4.2% of 200k budget). 6 of 31 skills unused in 4 weeks; top waster:

heavy-skill

(1,900 tokens, never used)."

Example 2: Longer lookback, custom budget

Input: "Check skill usage over the last quarter against a 500k window."
