Red-green-refactor as a repeatable move, not a suggestion.
Production-grade engineering skills for AI coding agents. Drop-in, reviewed capabilities that turn a general model into a disciplined engineer — testing, refactoring, review, and release, done the way a senior would.
Red-green-refactor as a repeatable move, not a suggestion.
Change the smallest surface; keep the diff reviewable.

Map the blast radius before touching a line.
Reproduce first, fix the root, confirm with a test.
Let the checker be the fast feedback loop.
Explain the why the code can't say on its own.
