Does it prevent committing broken code?

Yes, by making verification a prerequisite for task completion, it ensures that only code that has passed fresh local checks is ready for staging or PRs.

What counts as valid verification evidence?

Evidence includes terminal output showing zero test failures, exit code 0 for builds, clean linter reports, and confirmed line-by-line requirement checklists.

Why is this skill necessary for Claude Code?

It prevents the AI from making premature success claims by mandating the execution and analysis of actual verification commands before reporting completion.

How does this help with bug fixing?

It enforces a Red-Green cycle where the AI must prove the bug existed, apply the fix, and then provide fresh evidence that the specific symptom is gone.

Security & Testing

Enforces rigorous evidence-based reporting and mandatory verification commands before any task is marked as complete.

This skill implements a strict 'Iron Law' for AI-assisted development, preventing premature completion claims by requiring fresh, documented verification evidence. It introduces a gate function that forces the AI to identify specific verification commands, execute them in real-time, and interpret the full output before declaring success. By eliminating guesswork and speculative language like 'should work,' it ensures that tests pass, builds succeed, and requirements are genuinely met through actual terminal confirmation rather than assumptions.
