Demo Reviewer
A deliberately tiny skill that exists only to demonstrate the harness end to end (materialized ablations included). It has exactly two load-bearing pieces — a severity rule and a checklist reference — each targeted by one ablation below.
Severity rules
Label every finding with one of: Blocking, Minor, or Clean. State the label explicitly so the reader can triage at a glance. A change that ships without a test is at least Blocking.
Evidence
Back each finding with concrete evidence and follow the shared review checklist: see the review checklist.
