Fix stubborn bugs with a repeatable test.
Guides bug fixes through reproducible failures, targeted investigation, and regression checks.
When to use it
Use when asked to diagnose or debug something, or when the user reports broken behavior, errors, failures, or slowness.
Give it a failure or slowdown in a codebase; it reproduces the problem, applies a fix, and verifies it with the original scenario and a regression test when a suitable test seam exists.
