Operate as an agentic engineer using eval-first execution, decomposition, and cost-aware model routing.
Use this skill for engineering workflows where AI agents perform most implementation work and humans enforce quality and risk controls.
Apply the 15-minute unit rule:
Prioritize:
Do not waste review cycles on style-only disagreements when automated format/lint already enforce style.
Track per task:
Escalate model tier only when lower tier fails with a clear reasoning gap.
