Find why your code fails and verify the fix.
Diagnoses software failures from evidence and verifies authorized fixes against the original failing scenario.
When to use it
Use to investigate a failure, including compilation and type errors, or to implement and verify an authorized fix.
Give it a failure in your project; it diagnoses the cause and, when a fix is requested, makes scoped changes with a regression check.
What you provide
Directs documentation work to /w-docs if behavior or commands changed; whether that skill must be installed to complete the workflow is unstated.
