Claude Official Skill: doc-coauthoring

What it is

Doc-coauthoring is an official Claude Code skill from Anthropic that provides a structured three-stage workflow for collaborative document creation. It guides users through Context Gathering, Refinement and Structure, and Reader Testing to produce high-quality documentation, proposals, technical specs, and decision documents.

The skill activates when a user mentions writing documentation ('write a doc', 'draft a proposal', 'create a spec', 'PRD', 'design doc', 'RFC'). It transforms the typically unstructured writing process into a repeatable, quality-assured workflow.

How it saves time or tokens

Without this skill, writing technical documents with an AI assistant often results in incomplete first drafts that require extensive revision. The three-stage workflow front-loads context gathering so the AI produces better first drafts. The Reader Testing stage catches blind spots by testing the document with a fresh context (no prior conversation knowledge), which simulates how a real reader would experience the document. This reduces revision cycles and produces clearer, more complete documents.

How to use

1. Install the skill via Claude Code:

claude skill install anthropics/skills/doc-coauthoring

1. Or manually copy the SKILL.md content to your skills directory:

mkdir -p .claude/skills/doc-coauthoring
# Copy SKILL.md content to .claude/skills/doc-coauthoring/SKILL.md

1. Start writing by telling Claude what document you need: 'Write a technical spec for the authentication module' or 'Draft a PRD for the new search feature'.

Example

The three-stage workflow in practice:

# Stage 1: Context Gathering
Claude asks clarifying questions:
- Who is the audience for this document?
- What decision does this document support?
- What prior art or existing docs should I reference?
- What constraints or non-negotiables exist?

# Stage 2: Refinement and Structure
Claude builds each section iteratively:
- Brainstorm section content together
- Draft the section
- Review and refine with feedback
- Move to next section

# Stage 3: Reader Testing
Claude reads the doc with fresh context:
- Does the introduction explain the problem clearly?
- Are there gaps in the argument or logic?
- Would a reader new to this topic understand the proposal?
- What questions would a reviewer ask?

Common pitfalls

• Skipping the Context Gathering stage to save time results in weaker documents. The upfront questions prevent major rewrites later.
• Not providing enough context about the audience leads to documents pitched at the wrong technical level. Be explicit about who will read the document.
• Skipping Reader Testing removes the most valuable quality check. The fresh-context test catches assumptions and jargon that the author takes for granted.
