Test Runner

Run the right tests, not all the tests — then make red go green. This skill picks a scope (changed-only by default, matching the "scoped tests locally, full suite in CI" discipline), detects the runner, executes, and on failure reads the actual output and traces, applies a minimal targeted fix, and reruns until the suite is stable or it hits a genuine blocker.

It subsumes the "run the smoke suite and stabilize it" and "compile and fix the type errors in a loop" workflows behind one scoped entry point.

Contract

Inputs:

• A repository with a detectable test runner and package manager
• A scope: changed (default), full, a focused path/pattern, --since <ref>, or a type: unit / integration / e2e / coverage / types
• Optional --no-fix to report failures without editing anything
