What it does

Instead of just ghostwriting, Claude acts as a writing process guide:

  1. Context Gathering — asks about doc type, audience, desired impact, and templates; lets you info-dump freely, then follows up with 5–10 clarifying questions.
  2. Refinement & Structure — per section: brainstorm 5–20 candidate points → you keep/cut/merge → draft → surgical edits via str_replace instead of reprinting the whole doc.
  3. Reader Testing — hands the document to a fresh Claude (sub-agent) with zero conversation context and probes it with realistic reader questions to surface ambiguity, hidden assumptions, and contradictions.

Who it's for

  • PMs and engineers who regularly write PRDs, RFCs, design docs, decision docs
  • Writers who can draft but worry "will anyone else actually understand this?"
  • Team leads standardizing documentation quality

Examples

  • Technical spec: "Write a spec for refactoring the payments module" → Claude probes rejected alternatives and rollback plans, then builds it section by section.
  • Decision doc: Paste a team discussion thread; Claude organizes context, options, trade-offs, and decision, then Reader Claude flags "it's unclear why option B was rejected."
  • Exec proposal: For a one-pager, brainstorm 20 points and keep only the 5 that matter, producing a tight, filler-free document.
