A ratchet is a pre-commit check that counts deprecated patterns in your codebase against a hard-coded expected count. It fails in two cases: - Too many instances: Prevents proliferation via copy-paste - Too few instances: Congratulates you and prompts lowering the expected count
Code Ratchets is a community-contributed Claude Code skill in the content-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/code-ratchets/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when (1) migrating away from legacy code patterns, (2) enforcing gradual codebase improvements, (3) preventing copy-paste proliferation of deprecated practices, or (4) setting up pre-commit hooks to count and limit specific code patterns. A ratchet fails if pattern count exceeds OR falls below expected—ensuring patterns never increase and prompting updates when they decrease.
