Prefer executing the real path — the one-shot command, the actual agent loop, the failing test now passing, the app in front of you — over inspecting the code that would run. "Looks right" and "the code clearly does X" are smells to verify, not conclusions. Use whenever you're about to conclude from reading rather than from running, especially when execution is cheap and available.

Reading code tells you what should happen. Running it tells you what does. When both are available, running wins — and it's usually cheaper than the paragraph you'd write justifying the inspection.
These thoughts mean stop and run it:
Your 100% certainty in unfamiliar territory is a cue to check, not a green light. The "looks right" signal is exactly where inspection fails and execution catches it.
vanta run "audit stripe.com" runs the real persona + tools + provider in one shot — that's the Done test, so run that, not the direct tool call.A mock that returns success, a test that asserts nothing, a happy-path stub — these look like execution and prove less than honest inspection. If you stub it, the claim is ○ assumed, not ✅.
