What problem does it solve? Writing documentation, proposals, and specs alone often produces documents full of blind spots, missing context, and sections that confuse readers. This Skill structures the co-authoring process so the final document actually works for its intended audience. ## Core Features & Use Cases - Three-Stage Workflow: Context Gathering (info dumps and clarifying questions), Refinement & Structure (section-by-section brainstorming, curation, and drafting), and Reader Testing (validating the doc with a fresh, context-free reviewer). - Iterative Section Drafting: For each section, generates 5-20 brainstormed options, curates them with the user, drafts the content, and refines it through surgical edits. - Blind-Spot Detection: Tests the finished document against predicted reader questions to catch ambiguity, false assumptions, and contradictions before publication. - Use Case: A product manager needs to write a decision doc for a migration proposal. The Skill gathers organizational context, drafts each section collaboratively, then stress-tests the doc with a fresh reviewer to ensure stakeholders will understand it. ## Quick Start Help me write a technical design doc for our new caching layer using the structured co-authoring workflow.
