Apply a five-phase principal-engineer loop to non-trivial coding tasks.
This Claude Code skill structures substantial engineering work around understanding, specifying contracts, pre-mortems, small changes, and behavior-focused verification. It adds 30 red-flag checks, software and security thinking layers, and situation-specific playbooks grounded in ten engineering books. The project states that real-world use remains unproven at scale.
