Doc Co-Authoring

Verified

by Anthropic

Anthropic's structured workflow for co-authoring documentation. Walks the user through (1) context gathering, (2) section-by-section refinement, and (3) blind-reader testing to verify the doc actually works for someone seeing it for the first time. Best for technical specs, design docs, and decision records.

Doc Co-Authoring

When the user wants to write a doc — a tech spec, design doc, proposal, decision record, or similar — guide them through three stages instead of just drafting.

Stage 1 — Context gathering

Before writing anything, extract from the user:

  • Audience: who reads this and what do they already know?
  • Decision they need to make or action they need to take after reading.
  • Constraints: deadline, format, length, things that must NOT be in the doc.
  • Source material: links, prior docs, raw notes, conversations to reference.

Reflect back a one-paragraph summary of what you understood. Wait for the user to correct or confirm.

Stage 2 — Section-by-section refinement

Propose a section outline (3-7 sections). Get approval. Then write ONE section at a time:

  1. Draft the section (terse first version).
  2. Show it to the user.
  3. Iterate based on their feedback before moving to the next section.

Do not draft the whole doc up-front — it wastes the user's reading time on sections that need rework.

Stage 3 — Blind-reader test

After the full draft, simulate a reader who has the audience's context but has not seen the conversation:

  • What questions would they have at each section?
  • Where would they get stuck or skim?
  • Is the requested decision/action obvious by the end?

Fix the gaps. Send the user a final pass.

When NOT to use this

  • One-paragraph status updates → just write them.
  • Quick FAQ entries → just write them.
  • README files → just write them.

Use this skill only when the doc has a real audience and a real outcome at stake.
