Планирование покрытия тестами по уровням TDD

testing

vc-test-coverage-plan is a Claude Code skill that produces a TDD-first test plan for a given blast radius, assigning every covered area to one of four tiers: fully-automated, hybrid, agent-probe, or known-gap. Before any tier assignments are made, the skill must invoke vc-context-discovery and follow the full routing chain starting from all-tests.md — inferring commands from training data is explicitly prohibited, and missing context triggers a TIER_ASSIGNMENTS_BLOCKED hard stop. Each area gets a structured table with exact commands or steps, what the test proves, what it does not prove, and explicit gap resolution options. High-risk classes — auth, billing, schema migrations, public API changes, deploy and proxy behaviour, permission boundaries — require at minimum a hybrid gate, with a documented rationale if that tier is bypassed. The skill is designed for use in PLAN (Verification Evidence section), VALIDATE (after V2 fan-out), and EXECUTE phases (as section gates and a final regression suite).
