What commands can this skill use for verification?

It supports any CLI-based tool, including unit test runners (Jest, PyTest), linters (ESLint, Ruff), compilers, and custom verification scripts.

Does it support Test-Driven Development (TDD)?

Yes, it specifically enforces Red-Green patterns, requiring the AI to verify that a test fails before the fix is applied and passes afterward.

Why is this skill necessary for AI development?

It prevents the AI from prematurely claiming tasks are finished without proof, which reduces bugs, prevents broken builds, and saves developers from manual double-checking.

How does this prevent 'hallucinated' success reports?

The skill mandates a 'Gate Function' where Claude must identify a proof command, run it, and read the full output before it is allowed to use words like 'Done' or 'Fixed'.

安全与测试

Enforces a rigorous evidence-based workflow by requiring actual command output before any claims of success or task completion.

This skill implements a strict 'Iron Law' for Claude Code, preventing the AI from making premature or unverified claims about work status. It requires the execution of fresh verification commands—such as test suites, build processes, and linting checks—and mandates the analysis of exit codes and error logs before any task is marked as complete. By prioritizing evidence over assertions, it eliminates 'hallucinated' success, ensures code integrity, and builds trust between the AI and the developer during complex refactoring or feature implementation.
