## What it does

The skill inspects `SKILL.md` files across user, project, and codex scopes to fix common formatting defects. It restores missing `---` delimiters and inserts a fallback version tag of `1.0.0`. Missing descriptions are filled using folder names. Every check starts in dry-run mode, printing `[DRY RUN]` action lines until approved.

Adding `--prune` reveals broken symlinks pointing to deleted targets and empty directories without `SKILL.md`. Files change only under `--apply`. Every applied change gets recorded with timestamps inside `data/changelog.log`.

Plugin and marketplace skills are skipped entirely because local edits would get overwritten on the next update. Running the tool requires `bash 3.2+` and write permissions to skill directories like `~/.claude/skills`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add khendzel/skills-janitor --skill janitor-fix -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add khendzel/skills-janitor --skill janitor-fix -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add khendzel/skills-janitor --skill janitor-fix -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install khendzel/skills-janitor janitor-fix
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add khendzel/skills-janitor --skill janitor-fix -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/khendzel/skills-janitor --path skills/janitor-fix
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add khendzel/skills-janitor --skill janitor-fix -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/khendzel/skills-janitor/tree/HEAD/skills/janitor-fix/SKILL.md

## When to use it
- restore missing `---` delimiters in frontmatter headers
- populate blank description fields using folder names
- delete broken symlinks pointing to deleted targets
- prune empty skill folders lacking `SKILL.md`

## Example prompts
- /janitor-fix
- /janitor-fix --prune
- Clean up broken skill directories with /janitor-fix --prune --apply

# Auto-Fix

Automatically fix common skill issues. Dry-run by default — shows what would change without modifying files.

## Overview

Repairs frontmatter problems (missing delimiters, empty descriptions, missing version fields) across user, project, and codex-scope skills, and — in `--prune` mode — removes broken symlinks and empty skill directories. Plugin/marketplace skills are never modified (changes would be overwritten on update).

## Prerequisites

- Claude Code with the skills-janitor plugin installed (provides `scripts/fix.sh`)
- bash 3.2+ (the stock macOS bash works; no external dependencies)
- Write access to the user's own skill directories (`~/.claude/skills`, `./.claude/skills`, `~/.agents/skills`)

## Instructions

### Step 1: Preview first (always)

```bash
bash ~/.claude/skills/skills-janitor/scripts/fix.sh            # preview fixes
bash ~/.claude/skills/skills-janitor/scripts/fix.sh --prune    # preview broken/orphaned removals
```

### Step 2: Show the user the preview and confirm

Never jump straight to `--apply`. Present the `[DRY RUN]` lines and ask before writing.

### Step 3: Apply

```bash
bash ~/.claude/skills/skills-janitor/scripts/fix.sh --apply           # apply fixes
bash ~/.claude/skills/skills-janitor/scripts/fix.sh --prune --apply   # remove broken skills
```

What it fixes:

- Adds missing frontmatter delimiters (`---`)
- Fills empty `description` fields with a template
- Adds missing `version` field (defaults to "1.0.0")
- Generates template descriptions using the skill folder name

Prune mode finds and removes:

- **Broken symlinks** — skill folder points to deleted source
- **Empty directories** — skill folder with no SKILL.md
- **Orphaned skills** — user-scope copies of plugin skills

Safety model: dry-run by default (must pass `--apply` to write), skips plugin/marketplace skills, logs ALL changes with timestamps to `data/changelog.log`, always asks for confirmation before removing.

## Output

Per-skill action lines (`[DRY RUN]` / `[FIXED]` / `[PRUNED]` / `[SKIP]`) followed by a summary of fixable issues, skipped items, and prunable entries. In dry-run mode the summary ends with "Run with --apply to make these changes."

## Error Handling

1. **Error**: A fix produced an unexpected result in a SKILL.md
   **Solution**: Every applied change is logged in `data/changelog.log` with a timestamp — show the log entry and restore the affected field manually; template descriptions are meant to be replaced by the author.

2. **Error**: `[SKIP] Plugin/marketplace skill - don't modify`
