What problem does it solve? Teams often start testing without a structured plan, leading to duplicated coverage, missed high-risk areas, and unclear quality gates. This Skill produces a disciplined, risk-scored test design document so QA, architecture, and development teams agree on what to test, at which level, and in what order before implementation begins. ## Core Features & Use Cases - Dual-Mode Test Planning: Auto-detects system-level mode (PRD + ADR, producing separate Architecture and QA documents) or epic-level mode (single test plan per epic). - Risk Assessment Matrix: Classifies risks by category (TECH/SEC/PERF/DATA/BUS/OPS), scores probability × impact, and defines mitigation plans with owners and timelines for high-priority risks. - Prioritized Coverage Plan: Breaks acceptance criteria into P0-P3 scenarios mapped to test levels (E2E/API/Component/Unit) with execution strategy and interval-based effort estimates. - Use Case: A QA lead receives a new epic with acceptance criteria and runs this Skill to produce a test design document with a risk register, P0-P3 coverage matrix, quality gate criteria, and a handoff document for story decomposition. ## Quick Start Ask the AI to design a test plan for your epic or PRD, for example: "Let's design a test plan for Epic 3 based on the PRD and architecture docs."
