SKILL.md

Verification Before Completion

Overview

Enforces the evidence-first principle: every claim of success, fix, or completion must be backed by concrete evidence. Exit codes, test output, and logs are the only acceptable proof.

Evidence Types

  1. Exit codes: zero = success, non-zero = failure
  2. Test output: pass/fail counts, coverage percentages
  3. Logs: error messages, stack traces, resolution confirmation
  4. Build output: compilation success/failure with timestamps

Rules

  • Never claim "should work" without evidence
  • Never claim success without exit code 0
  • Never claim a bug is fixed without reproduction failure
  • Always capture and report exit codes
  • Always run the full test suite, not just targeted tests
  • Use timeout guards (timeout 60s) to prevent hanging

When to Use

  • Before completing any BUILD workflow step
  • Before claiming a DEBUG fix is verified
  • Before approving a REVIEW result
  • Before marking any task as done

Agents Used

  • integration-verifier (primary consumer)
  • component-builder (TDD evidence)
  • bug-investigator (fix evidence)
