What Code Verification does

Code Verification runs a post-change checklist to catch structural bugs like TDZ errors, import mismatches, dead code, and React effect issues. Use it after code changes, test edits, or before marking work complete.

Code Verification is cataloged under Quality on DirSkills. Code Verification comes from a repository tagged agent-skills, agents-md, ai, ai-agents and claude-code.

Documentation

README

Code Verification Skill

A systematic post-implementation verification workflow that catches the bugs AI coding assistants most commonly introduce. This is NOT a code review for style or architecture — it is a mechanical correctness checklist that catches structural errors (TDZ, imports, dead code, mock leakage, CSS orphans, React anti-patterns) that humans and AI both miss during implementation.

When to Use

This is the opening of the README. Read the full README on GitHub.
