doc-coauthoring

doc-coauthoring is a skill for Claude Code, Codex from joaquimscosta/arkhe-claude-plugins. It costs 49 tokens per session (833 once invoked), scanned A, original, MIT.

A guided workflow for creating technical documents with another person. It covers gathering context, refining drafts, and sometimes testing whether the document is clear to its intended readers.

In plain words
What is it for?
Use it for READMEs, API documentation, architecture guides, proposals, technical specifications, RFCs, and decision documents.
Why use it?
It reduces the risk of writing a document that misses important context or is hard for its audience to use. It also gives longer writing tasks a repeatable process.

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 yesterday.

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.

Doc Co-Authoring Workflow

Collaborative workflow for creating documentation that works for readers.

When to Offer This Workflow

Trigger conditions:

  • Writing documentation: "write a doc", "draft a proposal", "create a spec", "write up"
  • Code documentation: "write README", "create API docs", "document this code", "architecture docs"
  • Specific doc types: "PRD", "design doc", "decision doc", "RFC", "technical spec"
  • User starting any substantial writing task

Workflow Variants

Variant Stages Use For
Full Collaborative Context Gathering → Refinement → Reader Testing Proposals, specs, decisions, RFCs
Streamlined Collaborative Context Gathering → Refinement READMEs, API docs, architecture guides

Both variants use collaborative principles (clarifying questions, iterative refinement). Streamlined skips Reader Testing since code docs have different validation (working examples, API accuracy).

Three Stages Overview

Stage 1: Context Gathering

Close the gap between what the user knows and what Claude knows. Ask about doc type, audience, desired impact, and template. Encourage info dumping. Ask clarifying questions until understanding is sufficient.

Stage 2: Refinement & Structure

Build the document section by section. For each section: ask clarifying questions, brainstorm options, let user curate, draft, and refine through surgical edits. Use code documentation patterns as scaffolds for READMEs, APIs, etc.

Stage 3: Reader Testing (Full Collaborative only)

Test the document with a fresh Claude (no context bleed) to verify it works for readers. If sub-agents available, test directly. Otherwise, guide user through manual testing.

Initial Offer Template

When triggered, offer the workflow:

I can help you write that [doc type]. I use a structured workflow that helps
ensure the doc works well when others read it:

1. **Context Gathering**: You share relevant context while I ask clarifying questions
2. **Refinement & Structure**: We build each section through brainstorming and iteration
3. **Reader Testing**: We test the doc with a fresh Claude to catch blind spots
   (or skip for code docs like READMEs)

Would you like to try this workflow, or prefer to work freeform?

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.
