Doc Co-Authoring

Guides you through a structured workflow of co-authoring complex documents: outline → drafts → revision → final.

When to use

  • You're writing a long document (technical proposal, business plan, RFC, contract draft).
  • You want to collaborate with the AI in real iteration rounds without losing the thread.
  • You need a more structured process than "write whatever you can".

What it does

  • Asks the goal, target audience, ideal length.
  • Builds the outline together and validates it before writing.
  • Drafts section by section; pauses for feedback before each segment.
  • Final revision pass: consistency, coherence, hidden assumptions.

How to use

  1. Tell your AI: "I want to write [type of document] using doc-coauthoring".
  2. Answer the structured questions about goal and audience.
  3. Approve the outline.
  4. Iterate section by section.

Best for

Writing where structure matters as much as content: technical proposals, business plans, multi-part articles, mid-length books. Anyone who tends to "rewrite from scratch" because they lost the thread.

How does the install work? The button above opens TerminalSync (the desktop app) and downloads SKILL.md into ~/.claude/skills/doc-coauthoring/. If you have Codex, it also writes to ~/.codex/skills/doc-coauthoring/. Skills Sync replicates it across every machine automatically.
