doc-coauthoring

Three-stage workflow for co-authoring a substantive document with a user: (1) Context Gathering with meta-questions + info dump + clarifying questions; (2) Refinement section-by-section with clarify → brainstorm → curate → draft → surgical edits; (3) Reader Testing where a fresh assistant or subagent reads the doc cold and answers predicted reader questions to surface blind spots. Pairs with technical-writer, legal-researcher, and tax-researcher agents. USE FOR: co-author a document, write a spec, write a design doc, write a PRD, write an RFC, write a decision doc, write a proposal, draft a post-mortem, draft a Schriftsatz, section-by-section drafting, reader test a document, doc blind spot check, refine doc iteratively, info-dump workflow, brainstorm section options, surgical edit, fresh-eyes review. DO NOT USE FOR: short emails, code review, README authoring, pure copy editing (use grammar-check).
