What problem does it solve? When planning or validating a code change, teams often lack a structured way to decide which areas need automated tests, which need hybrid environment-dependent tests, and which gaps must be explicitly documented. This Skill produces a TDD-first test coverage plan that assigns every blast radius area to one of four tiers with exact commands and explicit gap resolution options. ## Core Features & Use Cases - Four-Tier Assignment Waterfall: Classifies each blast radius area as fully-automated, hybrid, agent-probe, or known-gap based on deterministic criteria. - High-Risk Class Enforcement: Forces a minimum hybrid tier for auth, billing, migrations, public APIs, deploy behavior, and trust-boundary logic. - Gap Resolution Tables: Documents every uncovered gap with four resolution options (write test, set up infra, accept as known-gap, backlog artifact) plus TDD failing stubs for fully-automated rows. - Use Case: During a VALIDATE phase of a feature plan touching an API route and a UI component, invoke this Skill to produce per-area test tables with exact commands, what each test proves, and backlog artifacts for untestable areas. ## Quick Start Ask the agent to generate a test coverage plan for the blast radius described in your current plan file, loading the test context chain first.
