The Playbook Library
A playbook is a versioned process with approval gates — not a prompt. The library spans the whole arc: build something new, understand what you inherited, transform the legacy, lock it down, and govern it at org scale. Each one runs the same way — understand, propose, plan, approve, execute, prove — across every surface: the IDE, the CLI, CI, or an agent skill.
Two flows, every major runtime.
Scaffold a new production app with the architecture studio.
