# Active plans and design briefs Keep accepted Designer handoff briefs and future implementation plans in this directory. Name phase briefs `phase__.md` and title them `Phase — `. Designer briefs capture the product goal, user experience, scope, success criteria, and questions for the spec-pipeline. They are planning inputs, not final architecture specifications; the architect writes those in `../specs/`. Move completed or superseded plan drafts to `../archive/plans/`.
