verification-before-completion
Verify work actually meets its brief BEFORE declaring it done — a structured self-review pass that catches the gaps, unmet requirements, and untested claims that 'looks finished' hides. Use when about to hand over any deliverable (document, code, analysis, plan), when past work kept coming back with 'you missed…', or as the standing final step of any multi-step task. Produces the verified deliverable plus a short verification record: what was checked, what was found and fixed, what remains open.

# Verification Before Completion Skill
"Done" is a claim, and most agents (and humans) declare it by *feeling* — the output looks complete, reads well, compiles. This skill replaces the feeling with a check: re-derive what was actually asked, audit the work against it, try to break it, and only then hand it over. The gap between looks-done and is-done is where rework lives.
## What This Skill Produces
- The deliverable, **after** fixes the verification pass surfaced
- A **verification record** (3-8 lines): checked against what, found and fixed what, still open what
- Honest **residuals**: anything not verified, stated rather than implied
## The Verification Pass
1. **Re-read the ORIGINAL ask — not your memory of it.** Requirements decay in working memory over a long task; the third instruction in the user's message is the classic casualty. List every explicit requirement and every implicit one (format, tone, length, audience) as a checklist. *Then* audit the work against the list, item by item.
2. **Check the claims, not just the presence.** A section existing isn't the section being right. For each substantive claim/number/behaviour in the deliverable: is it grounded (traceable to input, source, or test) or asserted? Every ungrounded assertion either gets grounded, gets labelled as an assumption, or gets cut.
