What problem does it solve? Writing documentation, proposals, and specs alone often produces documents that make sense to the author but confuse readers. This Skill structures the co-authoring process so context is fully transferred, each section is deliberately refined, and blind spots are caught before others read the doc. ## Core Features & Use Cases - Three-Stage Workflow: Context Gathering, Refinement & Structure, and Reader Testing guide the document from raw ideas to a reader-ready draft. - Section-by-Section Iteration: Brainstorming, curation, drafting, and surgical edits for each section of PRDs, design docs, decision docs, RFCs, and technical specs. - Reader Testing: Predicts reader questions and validates the document with a fresh, context-free reviewer to expose ambiguity and assumed knowledge. - Use Case: A product manager needs to write a decision doc for a migration plan. The Skill gathers organizational context, drafts each section through structured feedback, then tests the final doc against realistic reader questions before it is shared with the team. ## Quick Start Ask the assistant to help you write a design doc or proposal using the structured co-authoring workflow, starting with context gathering.
