Stop That Shit gives Codex a small task boundary: finish the requested work, and stop before inventing a second project.

This technical preview includes:

  • a Codex Skill with review, change, answer, and monitor task modes;
  • a two-event Guard for UserPromptSubmit and PreToolUse;
  • default stops for review-to-edit drift and recognized unrequested hashing;
  • explicit authority for dependencies, subagents, hashing, and optional file locks;
  • paired Bad Case / Good Case fixtures and a reproducible evaluation harness;
  • English and Chinese setup and contribution paths;
  • an optional Skill-only install with no Hook trust.

Verified on Windows and Linux with Node.js 18 and 22. An isolated Codex CLI 0.147.0 smoke test covered Guard review, Guard change, and the no-Hook Skill path.

This is a mitigation, not a guarantee. Hooks cover only supported events and tool paths, and LLM runs vary. The project does not claim a general improvement percentage from the current evidence.

The most useful contribution is a paired case: where Codex should have stopped, and the nearest situation where the same action was necessary.
