# Verification Before Completion

Before claiming any status (tests pass, build succeeds, bug fixed, requirement met): run the command that proves it in this message, read the full output, and make the claim together with that evidence. Fresh evidence only — a previous run, a partial check, or an agent's own success report does not count; verify agent results against the VCS diff.

Inside the superharness workflow, `superharness:finishing-a-development-branch` owns the single fresh full verification gate, the `verification.md` evidence schema, and the RevisionSet rules; this skill governs the evidence-before-claims discipline everywhere else.
