Skills-Agent: Skill for Claude Code

.agents/skills/clean/SKILL.md

clean is a skill for Claude Code, Codex from VoTruongDanh/Skills-Agent. It costs 58 tokens per session (1,020 once invoked), scanned A, original, MIT.

A cleanup skill for finding and removing unnecessary files, temporary files, generated artifacts, and caches from a project.

In plain words
What is it for?
Use it to clean development leftovers, review AI-generated files, remove build artifacts, or update ignore rules.
Why use it?
It reduces repository clutter while checking for version-control risks, uncommitted work, and files that should be preserved.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is VoTruongDanh/Skills-Agent's own configuration. It tells Claude Code and Codex how to work on Skills-Agent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Skills-Agent configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

clean scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Memory Protocol

START: Read .ai-memory.md from project root. Check for known junk patterns, previous cleanup history, and project-specific ignore rules. END: Update .ai-memory.md using Memory Compaction Rules with: what was cleaned, space recovered, ignore rules added, and recurring patterns.

Goal

Identify and remove unnecessary files generated by AI, build processes, or development tools without affecting the working codebase.

Agent Routing

  • If cleanup involves build artifacts/CI → read .kiro/skills/agents/agents/devops-engineer.md and apply its knowledge
  • If cleanup involves security-sensitive files → read .kiro/skills/agents/agents/security-auditor.md and apply its knowledge

Socratic Gate

Before cleaning, verify:

  1. Is the project under version control? (safety check)
  2. Are there uncommitted changes that could be lost?
  3. Any specific directories/patterns to preserve? If uncertain, ASK before proceeding.

Workflow

  1. Read Memory — Load .ai-memory.md for project context and past cleanup history.
  2. Scan the project for common junk file patterns.
  3. Identify AI-generated files that may be redundant or outdated.
  4. Present a clear list of files to be removed with sizes and reasons.
  5. Ask for confirmation before deletion.
  6. Remove approved files and report space saved.
  7. Suggest .gitignore updates if needed.
  8. Update Memory — Save cleanup results and new patterns to .ai-memory.md.

Common Junk Patterns

  • Temporary files: *.tmp, *.temp, *.bak, *.swp, *~
  • Log files: *.log, *.log.*, debug.log, error.log
  • Cache directories: .cache/, __pycache__/, .pytest_cache/, .mypy_cache/
  • Build artifacts: dist/, build/, *.pyc, *.pyo, *.class, *.o
  • Node modules: node_modules/ (if not needed)
  • IDE files: .vscode/, .idea/ (if not in .gitignore)
  • OS files: .DS_Store, Thumbs.db, desktop.ini
  • AI artifacts: Duplicate markdown files, unused generated code, test outputs

Safety Rules

  • Never delete files in version control (check git status first).
  • Never delete configuration files (.env, config.json, etc.) unless explicitly requested.
  • Never delete source code without explicit confirmation.
  • Always show what will be deleted before proceeding.
  • Preserve .gitignore and other dot files unless they're clearly junk.
  • Ask before removing entire directories.
  • NEVER delete .ai-memory.md — it is a persistent project memory file.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

clean is a skill published in the GitHub repository VoTruongDanh/Skills-Agent (2 stars, last pushed 6d ago), licensed MIT. It adds 58 tokens to every session and 1,020 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
