Verification Before Completion

Critical rules

  • NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE.
  • Agent confidence is not evidence. Only fresh command output is.
  • MUST: run the proving command this turn; show actual output and exit code/failure count; re-verify after any code change; verify all requirements, not only tests.
  • NEVER: "should"/"probably"/"seems to" for verified status; celebrate before running; commit/push/PR without verification; trust sub-agent success; rely on partial or previous runs.
  • Red flags: satisfaction language before commands, "just this once", any success wording without a fresh run.
  • Before matching claims to commands, read references/claim-matrix.md.

Workflow

  1. IDENTIFY the command that proves the claim.
  2. RUN it fully and freshly this turn.
  3. READ full output, exit code, failure count.
  4. VERIFY: output confirms the claim? If no → state actual status with evidence. If yes → state claim with evidence.
  5. ONLY THEN make the claim. Skip any step = lying, not verifying.

Resources

  • references/claim-matrix.md — claim→command table, correct patterns, TDD red-green, rationalizations. Read before claiming status.

Validation

  • [ ] Exact proving command identified
  • [ ] Command run in full this turn
  • [ ] Output and exit code/failure count read
  • [ ] Output confirms the claim
  • [ ] No "should"/"probably"/"seems to" for verified status
  • [ ] Sub-agent reports independently verified (diff or fresh output)

Constraints

  • No "trivial enough to skip" exception.
  • Related: tdd-workflow, debugging-methodology, testing-strategy, session-continuity, branch-completion.
