What it does
A skill for co-writing a document: it walks you through a structured co-authoring workflow — from key points and outline to draft and revisions, with explicit iterations, instead of dumping everything in one block. It helps keep the logic and tone of a long document consistent.
How to set it up
Ships as part of the example-skills bundle:
/plugin marketplace add anthropics/skills
/plugin install example-skills@anthropic-agent-skills
Or copy the doc-coauthoring/ folder into ~/.claude/skills/.
When to reach for it
- A long document (strategy, PRD, article) that should be assembled step by step with the model.
- You want a controlled "outline to draft to revision" process rather than one big generation.
Example
"Let's write the PRD for the new module together" — the skill first agrees on the structure and key points, then fills in the sections and revises them piece by piece.
