Add this skill

Claude

Claude Code loads skills from ~/.claude/skills/ (all projects) or .claude/skills/ (one project):

git clone --depth 1 https://github.com/amElnagdy/guard-skills.git
cp -r guard-skills/skills/clean-code-guard ~/.claude/skills/clean-code-guard   # personal, or .claude/skills in a project

In the Claude apps, zip the clean-code-guard folder and upload it under Customize > Skills > + > Upload a skill (code execution must be on).

ChatGPT / Codex

Codex reads skills from .agents/skills/ in a repo or ~/.agents/skills/ for every project:

git clone --depth 1 https://github.com/amElnagdy/guard-skills.git
cp -r guard-skills/skills/clean-code-guard .agents/skills/clean-code-guard   # repo; ~/.agents/skills for all projects

Standalone skills also load in the ChatGPT desktop app.

Cursor

Cursor loads skills from .cursor/skills/ (or ~/.cursor/skills/) and also reads .claude/skills/:

git clone --depth 1 https://github.com/amElnagdy/guard-skills.git
cp -r guard-skills/skills/clean-code-guard .cursor/skills/clean-code-guard   # project; ~/.cursor/skills for all projects

What this skill does

Review generated or changed production code before it ships, using Clean Code, SOLID, DRY, KISS, YAGNI, and LLM-specific failure-mode checks in any programming language. Best used reactively after an agent writes, edits, refactors, or fixes code, before presenting, committing, or merging the result. Use when the user asks "review this PR", "is this safe to merge?", "make this cleaner", "audit this code", "refactor this", "fix this bug", or after a coding agent produced implementation code.

When it triggers

  • Use when the user asks "review this PR", "is this safe to merge?", "make this cleaner", "audit this code", "refactor this", "fix this bug", or after a coding agent produced implementation code.
  • Invoke it on your own initiative the moment you finish writing, editing, or refactoring non-trivial production code, before presenting or committing — don't wait to be asked.
  • USE for factual/conceptual questions, CI/tooling config, git workflow, running/debugging tests, pure architecture discussion, prose writing, data analysis, or test-code review (use test-guard).
  • "review this PR"
  • "is this safe to merge?"
  • "make this cleaner"
  • "audit this code"
  • "refactor this"
