概要
The Document Co-Authoring skill transforms Claude into an active writing partner for technical specifications, PRDs, and proposals. It follows a rigorous methodology that begins with deep context gathering to bridge information gaps, moves into iterative section-by-section drafting with brainstorming options, and concludes with an automated 'Reader Test.' This final stage uses a fresh Claude instance to simulate an uninformed reader, identifying blind spots and ensuring the document is high-quality and self-explanatory before it reaches human reviewers.
