Done-Means-Verified Checklist as an AI skill. It asks for What was changed, Claims to verify, Commands available and 2 more, then does the rest. Free to…

When it is used

Use when work is about to be called finished and every claim of success needs proof from commands actually run. Do not use for planning the work or reviewing code style. Related topics: coding, productivity.

What it will ask you for

• What was changed (longer free text)
• Claims to verify (longer free text)
• Commands available (longer free text)
• Done criteria (longer free text)
• Evidence depth (choose one: Quick, Standard, Exhaustive)

How it works

1. List every claim the finished work implies, from passing tests to a bug no longer reproducing.
2. Run a fresh command for each claim and read its real output instead of reusing earlier results.
3. Mark each claim verified, failed or unverified with the quoted evidence or reason.
4. Compare the verified results against the requester's done criteria one by one.
5. Report what is proven, what is not, and what remains, leading with any failure.

What you get

A claim table with columns claim, command, result and status, followed by a short plain statement of what is proven and what is outstanding.

What it watches out for

• Quoting a test result from before the last edit, which can be stale by the time of the claim.
• Treating a command that exited quietly as a pass when it never ran the relevant tests.
• Burying a failed check under a long list of passes.
