SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents false claims of completion, incomplete work, and broken trust by mandating rigorous verification before any success assertion. It enforces an "evidence before claims" principle, ensuring all work is thoroughly checked.

Core Features & Use Cases

  • Mandatory Verification Gate: Requires identifying, running, reading, and confirming output of verification commands before making any claims.
  • Anti-Rationalization: Explicitly counters excuses for skipping verification, such as "should work now" or "I'm confident."
  • Comprehensive Checklist: Provides a table of common claims and the specific evidence required for each (e.g., test output for "tests pass").
  • Use Case: Before committing a bug fix, use this skill to run the relevant test command, confirm "0 failures" in the output, and then confidently claim the bug is fixed.
