blueprint

Turns a one-line goal into a step-by-step build plan for multi-session, multi-agent engineering projects. Each step includes a standalone context brief so a new agent can execute it directly. Includes adversarial review gates, dependency graphs, parallel step detection, an anti-pattern catalog, and a plan mutation protocol. Triggers when the user requests a plan, blueprint, or roadmap for a complex multi-PR task, or describes work requiring multiple sessions. Does not trigger when the task can be completed in a single PR or fewer than 3 tool calls, or when the user says "just do it."
