test-plan

Use when user requests user-guided test plans, UAT validation, acceptance criteria definition, or user journey testing. Triggers on: "test plan", "user journey test", "UAT", "acceptance criteria", "manual test plan", "user-guided test", "validate from user perspective", "walk me through testing", "define what to test". Takes an implementation plan file as input and produces a test plan document with user personas, Given/When/Then scenarios, manual UAT steps, traceability matrix, and optional BDD .feature files. Annotates the input plan file so downstream skills (/swarm, /plan-review, /pr-review, /fix, /quality-gate) discover and consume the test plan automatically.
