Agent Skills: test-runner

Run a project's tests at the right scope — changed-only, focused, full, type-check, or e2e — then report failures with evidence. Repair and rerun only when fixing failures is explicitly authorized. Detects the test runner in a Bun-managed repo. Use when the user asks to run tests, run the suite, run smoke/e2e tests, type-check, check the build compiles, fix failing tests, or runs /test run.
