What problem does it solve? Teams often ship code without systematic test planning or independent verification, leading to missed edge cases, scope drift, and regressions. This Skill provides a Quality Guardian role that plans testing upfront and rigorously validates implementations against requirements before merge. ## Core Features & Use Cases - Test Planning Mode: Generates structured test plans mapping requirements to unit, integration, and edge-case test scenarios with acceptance criteria tables. - Verification Mode: Runs existing test suites, checks acceptance criteria, enforces TDD commit patterns (red/green/refactor), and detects scope drift and coherence issues against the PRD and architecture. - Plugin Lint Mode: Validates the Circle plugin's internal consistency across 8 checks including skill registry sync, frontmatter validity, workflow gate integrity, and version alignment. - Use Case: After an implementation is complete, invoke the skill to produce a test report with a PASS/CONDITIONAL PASS/REJECT verdict, P0-P3 issue severity ratings, and a traceability table linking code back to PRD work items. ## Quick Start Ask the assistant to verify the current implementation against the requirements and produce a test report with a quality gate verdict.
