Writing Specs Agents Can Execute

Obvious's three-phase framework for specs an AI coding agent can actually execute: a product spec (outcomes, success criteria), a UX spec (the experience, before code), and a technical spec (implementation in the real codebase) — each phase feeding the next. Skip a phase and the agent has to guess, and the mismatches show up in code review.
