This is your final quality pass before shipping a working workflow. It runs through a comprehensive checklist covering prompts, tool descriptions, error messages, logging, and configuration, then tells you exactly what's broken, where it is, and how to fix it with a priority rating. The checklist is opinionated but practical: four-zone prompt patterns, explicit output schemas, specific error messages with corrective actions, PII redaction in logs, no magic numbers. It explicitly won't change behavior or suggest redesigns, just polish what already works. Best used after your workflow functions correctly but before you'd feel comfortable handing it to someone else. The mandatory context gathering step means it needs existing workflow state to audit against.
