doc-coauthoring

A step-by-step method for writing clear product requirements, technical proposals, design documents, and decision records from incomplete information.

In plain words
What is it for?
Use it to plan and draft PRDs, RFCs, specifications, proposals, and decision records, or to turn a discussion into a document the wider team can use.
Why use it?
It prevents important context, assumptions, tradeoffs, and next steps from being lost. It also checks whether the document makes sense to readers who were not part of the original discussion.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

doc-coauthoring scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Doc Co-Authoring

Turn partial context into a clear document by following a staged workflow. Keep the user in control of decisions, and optimize for a doc that works for readers who do not share the author’s context.

Triggers

Use this workflow when the user asks to:

  • write or refine documentation, proposals, RFCs, PRDs, decision docs, specs
  • “summarize our discussion into a doc”
  • “make this readable for others” / “share with the team”
  • create a template or standard for recurring documents

If the user explicitly wants freeform writing, keep the workflow lightweight (ask fewer questions; draft faster).


The Workflow (3 stages)

Stage 1 — Context Capture (close the gap)

Goal: collect the minimum context required to write a doc that is correct, scoped, and actionable.

Ask for:

  1. Doc type + goal: what is this document for, and what decision/action should it unlock?
  2. Audience: who will read it, and what do they already know?
  3. Constraints: deadlines, non-goals, dependencies, security/compliance, platform limits.
  4. Current state: what exists today? what’s broken? what’s missing?
  5. Options considered: at least 1–2 alternatives and why they may/ may not work.
  6. Success criteria: how we know it worked (metrics, user outcomes, acceptance tests).
  7. Open questions: unknowns that block writing certain sections.

Output of Stage 1:

  • a short “context snapshot”
  • a list of open questions (ranked by importance)
  • a proposed doc outline (1 screen)

Stage 2 — Outline-First Drafting (iterate by section)

Goal: draft a document in layers without losing coherence.

Rules:

  • Outline before prose. Do not write full paragraphs until the outline is agreed.
  • One section at a time. Draft → review → revise, then move on.
  • Maintain a decision log (small bullet list) so changes are explicit.
  • Keep unknowns visible: unresolved items stay in an “Open Questions / Risks” section, not hidden.

Recommended iteration loop per section:

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
