Un seul agent, un playbook par métier : la délégation en trois pièces
Method told by [Cooper Simson](https://www.instagram.com/reel/Dec_uC2tRTg/): instead of building one agent per task and wiring them together, you keep a single agent and give it three pieces for each role. A playbook drawn from an interview about your job, a toolbox where everything it produces is stored and linked back to the playbook, and a proof: the list of what "done" means. A practitioner's field report, not a measured method.
