By name: atomic-verify description: > Evidence-before-claim gate. Auto-triggers when Claude is about to claim "done", "fixed", "passing", "complete", "ready to merge", "looks good", "should work", "should pass", "green", or any synonym. Iron rule: no completion claim without a fresh verification command run in this turn. Explicit invocation: /atomic-verify.
Verify before claim. No claim without fresh evidence in this turn.
- "done", "fixed", "passing", "complete", "ready to merge", "looks good"
- "should work", "should pass", "this works"
- "tests pass", "build green", "lint clean", "typecheck green"
- "bug fixed", "regression resolved"
- Any phrase implying success not preceded by verification output IN THIS TURN.
The gate
- IDENTIFY — what command proves this claim?
- RUN — execute it fresh in this turn.
- READ — full output, check exit code.
- VERIFY — output matches the claim?
- ONLY THEN — state the claim, WITH evidence.
Skip any step = lying, not verifying.
Claim → required check
| Claim | Required verification |
|---|---|
| tests pass | run test command, see 0 failures |
| build green | run build, exit 0 |
| lint clean | run lint, 0 errors |
| typecheck green | run typecheck (tsc/mypy/etc), 0 errors |
| bug fixed | run repro that failed before, see it pass now |
| agent task complete | check VCS diff for actual changes |
| regression test works | red → fix → green sequence verified |
| spec/artifact changed | run atomic validate spec + atomic validate config + atomic validate artifacts, 0 FAIL (skip if atomic binary absent) |
Verification discipline
Every completion claim needs a fresh command run in this turn. Watch for these moments:
- Before saying "done" or "fixed" — run the proof command first
- Before committing or pushing — verify all signals are green
- After a subagent reports success — check the artifacts yourself
- Partial checks (one test out of N) are not verification — run the full suite
- When the change touched
docs/spec/**,docs/design/**, or bundled artifacts (agents/,commands/,skills/,output-styles/,rules/,CLAUDE.md), runatomic validate spec(when a spec changed),atomic validate config, andatomic validate artifacts. A FAIL is a gate failure with the same standing as a failing test. Graceful degradation: if theatomicbinary is not on PATH or no matching files exist, skip silently — never fail the gate on absence. (This skill ships to user repos that may not have the binary installed.)
When tempted to skip
| Temptation | What to do instead |
|---|---|
| "Should work" | Run the command. Evidence over confidence. |
| "Linter passed" | Linter ≠ build ≠ tests. Run all applicable checks. |
| "Subagent said success" | Verify the diff yourself. |
| "Partial check is enough" | Run the full suite. Partial proves nothing about the rest. |
Boundaries
- Fires only when Claude transitions from "doing" to "asserting done."
- Intent statements ("I'll fix it") are future — no gate needed yet.
- Progress reports ("ran tests, 2 failures") are evidence without a completion claim — no gate needed.
