When someone says "did that fix it" or "prove it works," this skill forces you to capture baseline and treatment evidence from the actual system, compare them, and return one of three verdicts: VERIFIED, NOT VERIFIED, or INCONCLUSIVE. It walks you through restating vague claims as falsifiable tests, picking a minimal local surface like a CLI command or screenshot, and diffing raw artifacts with the same environment and warmup. The workflow is opinionated about structure and honest about negative results. If you've ever merged a PR based on "trust me, it's faster now" and later regretted it, this gives you the repeatable evidence habit you were missing.
