Overview
This skill front-loads a written specification — objectives, structure, and explicit boundaries — before implementation begins. It reduces rework by making intent and scope concrete up front, part of Addy Osmani's define-plan-build lifecycle.
What it is good for
- Writing a PRD before coding
- Clarifying scope and boundaries
- Aligning an agent on objectives
- Reducing mid-build rework
