Impostor Hunt
v1.0.0Hunt the impostor in a "finished" deliverable. An impostor is a result-correct artifact whose causal chain is NOT the one the user's purpose required — the test set leaked, only the happy path is wired, correlation got relabeled as cause, the config file exists but no code path reads it, the wrapper greps stdout for "OK" without checking the exit code, the agent "can refactor" backed by one cherry-picked example. The output looks right. The logic that produced "right" is the wrong logic. AUTO-INVOKE when a turn declares completion AND the user's original purpose is recoverable from context. Completion signals include: "done", "implemented", "finished", "works now", "ready to merge", "all tests pass", "task complete", "feature shipped", an agent posting a summary with checkmarks, a PR description, a CHANGELOG entry, or a closing message that asserts the work is over. Original purpose is recoverable from: the user's first message in the thread, the issue/ticket text, the PR title and description, the commit message that opened the branch, the README's stated goal, or an explicit prompt the user pasted at the start. If both signals are present, invoke without waiting for an explicit request. Also invoke when the user explicitly asks to audit completion truth, detect fake completion, check for hidden goal misalignment, look for mock-driven success, test-set leakage, happy-path-only delivery, correlation-as-causation, configured-but-unread settings, logs-say-success-but-return-code-unchecked, or similar patterns. Triggers in any language; the report mirrors the user's language. DO NOT invoke for ordinary bug hunting (route to code-review), style or refactor cleanup (route to simplify), or behavior-by-execution verification (route to verify / run). DO NOT invoke when the user is mid-implementation and has not yet declared the work done — interrupting an in-flight task with a completion audit is noise. DO NOT invoke when the original purpose is not recoverable from context; ask for it first instead of guessing.
