What problem does it solve? Work declared done without direct verification has unknown correctness. Indirect signals like file timestamps, cached output, successful compilation, or an agent's own summary can all be wrong, and acting on a wrong inference costs far more than checking the source. ## Core Features & Use Cases - Direct Verification Discipline: After any task, check the real thing: run the feature, read the actual value, inspect the git diff, and confirm data flows from input to output. - Delegation Auditing: When verifying delegated or agent-produced work, inspect the actual output artifact (diff, file contents, runtime behavior) rather than trusting the delegate's summary. - Scripted Proof: Write a deterministic script that re-runs the same comparison so a reviewer can re-run it instead of trusting a one-time eyeball, keeping the artifact visible for the human. - Use Case: After an agent claims it fixed a data pipeline bug, run the pipeline end-to-end and diff the old and new compiled output with a script rather than accepting the agent's report. ## Quick Start After finishing a task, ask how to prove it actually works, then run the feature or inspect the real artifact directly before declaring it done.
