vc-test-coverage-plan

Output style: Follow process/development-protocols/communication-standards.md — answer-first, plain language, no unexplained jargon, TL;DR on long responses.

Generate a TDD-first full test plan per blast radius area. Assigns all 4 test tiers with exact commands, what each proves, what it does NOT prove, and explicit resolution options for every gap.

Boundary vs vc-feasibility-test

This skill is POST-decision: the design is already chosen and you are assigning coverage tiers across a known blast radius. If instead an approach cannot be decided because a runtime/library/external mechanism is unverified — that is a PRE-decision question and belongs to vc-feasibility-test (a one-shot empirical probe producing a VIABLE/NOT-VIABLE/INCONCLUSIVE VERDICT), run before SPEC/INNOVATE locks. Do not use test tiers to answer "does this mechanism work at all?".

When To Invoke

• PLAN phase — populate the Verification Evidence section of a new plan
• VALIDATE Section III — generate the full test plan after V2 fan-out, before writing the validate-contract
• EXECUTE phase — as test gates at the end of each plan section and as a regression suite after all sections complete

Context Discovery (MANDATORY FIRST — do this before anything else)

This skill MUST NOT infer tiers, commands, or runners from training data. Before reading the plan or naming a single area:

1. Invoke vc-context-discovery to load the relevant context group files.
2. Read process/context/tests/all-tests.md and follow its downstream routing chain to the relevant deeper test docs (tests/container-e2e.md, tests/browser-automation.md, tests/live-e2e.md, etc.). The entry point is a router, not full knowledge — reading only the router and skipping the chain is insufficient.
3. Discover the existing test files inside the blast radius (real runners + real commands + real fixtures — not guesses).

Hard stop (mirrors vc-plan-agent TIER_ASSIGNMENTS_BLOCKED): if the all-tests.md routing chain was not loaded, or existing blast-radius test files were not discovered, STOP and emit TIER_ASSIGNMENTS_BLOCKED — report BLOCKED with "Test context chain not loaded; returning to RESEARCH to load all-tests.md and discover existing test files. Do not generate tier assignments from training data." Do NOT proceed to the waterfall. Every Command / Steps cell below must be an exact command sourced from the loaded test context, never an inferred placeholder.
