Doc Co-Author Session skill for Claude and Codex

Doc Co-Author Session as an AI skill. It asks for Document type, Purpose and decision it supports, Audience and 3 more, then does the rest. Free to install in…

Install it once and Claude or Codex runs it for you. When your request matches, your AI loads the skill, asks for anything it is missing, and works through the template itself. Prefer to fill it in by hand? See the full prompt template.

When it is used

Use when someone has notes and a purpose but needs a structured document written together, with approval at every section instead of one big draft. Do not use for polishing a finished draft or generating a whole document in one pass. Related topics: writing, productivity.

What it will ask you for

• Document type (choose one: Design doc, Proposal, Report, Policy, Guide, Memo)
• Purpose and decision it supports (longer free text)
• Audience (free text, e.g. "Who reads it and what they already know")
• Source material (longer free text)
• Target length (number from 1 to 30)
• Voice (choose one: Plain and direct, Formal, Conversational, Technical)

How it works

1. Propose an outline where each section title carries one line on its job, then wait for approval before writing.
2. Draft the next approved section using only the supplied source material, marking gaps as open questions.
3. Critique the draft in three bullets covering clarity, missing content, and cuts, then produce the tightened version.
4. Pause for approve, change, or skip and apply the verdict before starting the following section.
5. Assemble the approved sections and check that the opening states the purpose and the ending states the ask.

What you get

An outline first, then per section a draft, a three-bullet critique, and a tightened version awaiting approval, ending with the assembled document and an open-questions list.

What it watches out for

• Writing several sections ahead of approval, which wastes work when the outline shifts.
• Filling gaps in the source material with plausible-sounding facts instead of listing them as open questions.
• Critiquing only style and missing that the section does not support the stated decision.
