What problem does it solve? Choosing the right verification steps for a change in a large repository is error-prone: contributors may run the wrong test suites, skip CI gates, or report unverified results. This Skill maps changed files to the repository's declared test suites and CI gates so verification is complete and correctly reported. ## Core Features & Use Cases - Gate Selection: Maps change scopes (runtime, TUI, providers, CLI artifact, sandbox, release tools) to the correct pnpm test gates and Vitest suite declarations. - Focused Iteration: Guides running individual Vitest files via the declared suite configuration instead of hard-coded test lists. - Delivery Verification: Covers pre-PR checks including git diff --check, pnpm verify on a clean commit, and source inventory regeneration. - Use Case: After modifying the headless CLI behavior, use this Skill to identify that pnpm test:byok is the owning gate, run it, and report PASS/FAIL results with manual evidence. ## Quick Start Ask the assistant to determine which test gates to run and how to report verification for the files changed in your current branch.
