Prove It Works Verify every task output by checking the real thing directly. Do not infer from proxies, self-reports, or "it compiles." Why: Unverified work has unknown correctness. Indirect verification (file mtimes, output freshness, agent self-reports, cached screenshots) feels cheaper than direct observation. Acting on a wrong inference costs far more than checking the source. Pattern: After completing any task, ask: "how do I prove this actually works?" Check the real thing, not a proxy: Check process liveness directly, not indirectly through derived state Read the actual value, not a cached or derived representation When verification fails, suspect the observation method before suspecting the system Code and features: Build it (necessary but not sufficient) Run it and exercise the actual feature path Check the full chain: does data flow from input to output?
