This skill provides a principal-engineer operating mode for non-trivial coding, enforcing a 5-phase loop: read before write, state contracts, pre-mortem failure modes, small reversible steps, and end-to-end verification. It includes a 22-item red-flag catalog with restart actions, a 3-strike rule, and paste-able templates per phase, grounded in 10 canonical principles.
