Overview
What it does
Rather than writing a document in one go, this skill has Claude run a structured process. First it gathers context with targeted questions and lets you dump everything you know. Then it builds the document section by section: clarifying questions, brainstorming, curating what to keep, checking for gaps, drafting and refining.
The last stage is the unusual one. Claude predicts the questions a reader would ask and, where subagents are available, hands the draft to a fresh agent with no context to see whether the document answers them on its own. Gaps it finds go back into the draft.
Triggers
When Claude uses it
- Writing documentation, proposals, technical specs or decision documents.
- Any request to draft structured content that other people will read.
What it needs
- Nothing to install: a single SKILL.md with no scripts.
- The repository includes no licence file for it, so we link to it rather than republish it.

/plugin install example-skills@anthropic-agent-skillsThe example-skills plugin installs 12 skills from this repository, including this one. Its skills are then namespaced, such as /example-skills:doc-coauthoring.
Its licence doesn’t allow copies, so we don’t give a copy command. Install it with the plugin above.
claude.ai and the Claude API

Checks
SKILL.md validator results
Its SKILL.md (375 lines) run through our SKILL.md validator, with the folder’s file list, for both targets. These check the file’s format, not whether the skill works well.
