What problem does it solve? Passing automated tests and code review do not prove a feature actually works for real users. This Skill closes that gap by running the product end to end, exercising edge cases and failure states, and producing an evidence-backed release verdict. ## Core Features & Use Cases - End-to-end verification: Exercise the feature as a real supported user, then probe boundaries, state, permissions, failure recovery, and lifecycle paths with time-boxed exploratory charters. - Structured verdicts and reporting: Report PASS, PASS WITH KNOWN ISSUES, FAIL, BLOCKED, or INCONCLUSIVE alongside a separate ship/hold recommendation, with reproduction steps and evidence for every finding. - Disciplined intermittency handling: Preserve first failures, forbid retry-until-green, and require a stated diagnostic protocol for flaky results. - Use Case: Before shipping a new checkout flow, use this Skill to run the flow on staging with synthetic data, test double-submit and payment-timeout behavior, inspect logs and database state, and deliver a release verdict with documented residual risk. ## Quick Start Use the qa skill to verify the new checkout flow on staging and report a release verdict with reproduction steps for any issues found.
