authoring-test-plan
authoring-test-plan
bm629 / agent-skills

Use when authoring or amending a test plan / QA verification plan — what to test, at what level, to what done-criteria, and the cases to run. Guides the METHOD, not the outline: deriving every case from a feature-spec behavior/AC or api-spec operation/error (never inventing one); the functional levels the project warrants; RISK-WEIGHTED catalog sizing (BVA/equivalence/decision-table/state-transition/pairwise, not the cross-product); a non-functional taxonomy (perf/security/accessibility WCAG 2.2 AA/compat/i18n) each with a numeric target where warranted; metric-threshold-on-a-named-dataset cases for ML/probabilistic behavior; and amending as a versioned delta with impact+risk regression selection — to a bar where a tester executes it with no questions, every behavior traced. Composes with a template tool + deep-research; consumes handed-in upstreams (feature-spec/api-spec/PRD/NFRs), never a blank page. Specs the cases, not the scripts; not the runbook, not the behavior contract, not reviewing one.
