design

Design the shape of a new feature, service, or component before code — software, infrastructure, or both. Ground in the real system, sketch two structurally different designs with cheap Sonnet runners, screen them against red flags, write a proposed ADR in docs/adr, then stop for sign-off and offer /phase shape. Triggers on "/design", "architect this", "design this first", or non-trivial work where jumping to code or IaC would lock in the wrong shape. Optional leading level.
