## What it does

skill-cleaner runs the `skill-cleaner.ts` analyzer and produces a report on loaded skills, descriptions, roots and usage evidence. It flags long descriptions that add prompt pressure, duplicate names or near-copy `SKILL.md` bodies, plus roots marked disabled by configuration.

By default, it gets the model-visible inventory from `codex debug prompt-input`; the filesystem scan is used for duplicate, disabled and archive-cache checks. The report accounts for a 2% context budget, alias-table line cost and description truncation. `--no-live` switches to a broader filesystem fallback, while `--root-only` scans only paths supplied with `--root`.

Log evidence is heuristic: the script checks `$skill`, `use skill`, and paths seen in tool-call arguments. That means deletion candidates need a manual check. The skill suggests cleanup first and only edits or deletes files after a direct request; ignored or untracked directories require a stated destination or confirmation.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add steipete/agent-scripts --skill skill-cleaner -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/skill-cleaner/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/skill-cleaner/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add steipete/agent-scripts --skill skill-cleaner -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/skill-cleaner/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add steipete/agent-scripts --skill skill-cleaner -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/skill-cleaner/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install steipete/agent-scripts skill-cleaner
```

2. **Manually: put the files in place**
- File: `.github/skills/skill-cleaner/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add steipete/agent-scripts --skill skill-cleaner -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/steipete/agent-scripts --path skills/skill-cleaner
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/skill-cleaner/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add steipete/agent-scripts --skill skill-cleaner -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/steipete/agent-scripts/tree/HEAD/skills/skill-cleaner/SKILL.md

## When to use it
- calculate prompt budget used by skill descriptions
- detect duplicate names and near-copy skill files
- flag skills with no recent usage evidence
- inspect disabled skill roots
- compare loaded inventory with filesystem copies

## Example prompts
- "Run skill-cleaner for `--months 3` and show the skill budget."
- "Find duplicate skills and list deletion candidates without changing files."
- "Scan only `~/.agents/skills` with `--root-only` and skip logs."

# Skill Cleaner

Use this when trimming skill prompt budget, finding duplicate skills, auditing enabled/disabled skill roots, or deciding which skills/plugins to remove.

## Workflow

1. Run the analyzer from this skill directory or repo root:

```bash
node --experimental-strip-types skills/skill-cleaner/scripts/skill-cleaner.ts --months 3
```

Useful variants:

```bash
node --experimental-strip-types skills/skill-cleaner/scripts/skill-cleaner.ts --no-logs
node --experimental-strip-types skills/skill-cleaner/scripts/skill-cleaner.ts --no-live --no-logs
node --experimental-strip-types skills/skill-cleaner/scripts/skill-cleaner.ts --months 6 --max-log-mb 800 --deep-logs
node --experimental-strip-types skills/skill-cleaner/scripts/skill-cleaner.ts --context-tokens 272000 --budget-percent 2 --no-logs
node --experimental-strip-types skills/skill-cleaner/scripts/skill-cleaner.ts --root ~/Dropbox/boxd/skills --no-logs
node --experimental-strip-types skills/skill-cleaner/scripts/skill-cleaner.ts --root ~/.agents/skills --root-only --no-logs
```

2. Read the report in this order:
- `Skill Budget`: live Codex inventory, 2% budget, budgeted usage, and full-description pressure.
- `Description candidates`: long descriptions where relaxed grammar saves prompt budget.
- `Duplicates`: same skill name or near-identical description/body across Codex, plugin cache, repo siblings, and personal skill roots.
- `Unused candidates`: no recent user mention or actual `SKILL.md` read in recent Codex/OpenClaw logs.
- `Root summary`: where skills came from and whether config marks them disabled.

3. Before deleting or editing:
- Verify the kept copy exists and is loaded.
- Prefer deleting repo-local or `agent-scripts` duplicates when Codex built-ins cover them.
- Keep repo-local OpenClaw maintainer skills when they encode repo policy or live operations.
- Preserve trigger nouns in descriptions: product, tool, action, object.

## Analyzer Notes

- By default, `codex debug prompt-input` supplies the exact model-visible skill list, order, names, and aliased paths. `--no-live` forces the broader filesystem fallback.
- The broad filesystem scan remains for duplicate, disabled, and archived-cache diagnostics; it is not treated as the loaded inventory.
- The script mirrors Codex's model-visible line shape: `- name: description (file: path)`.
- It applies Codex-like frontmatter rules: YAML frontmatter only, default name from parent dir, single-line sanitized `name` and `description`.
