Test cmux changes with evidence that counts.
Guides scoped verification and behavioral regression testing for cmux changes, including validation of Swift test targets and wiring.
When to use it
Use when adding tests or deciding which local and CI checks a change needs.
It changes how the agent verifies project changes, adds behavioral tests, and demonstrates that regression fixes work.
What you provide
The initial scoped verification command runs with Python 3.
Swift syntax verification uses an installed compiler to parse selected Swift files; it does not typecheck or execute tests.
