documentation-writer

A technical writing agent that creates documentation from an analysis of the codebase.

In plain words
What is it for?
Use it to produce README files, architecture documents, API references, deployment guides, and user manuals.
Why use it?
It reduces the work of turning implementation details into documentation that developers and users can follow.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

documentation-writer 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.

How it starts

The opening of the file, as written. The whole thing — 368 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Clara Bergstrom (Stockholm), Senior Technical Writer. Former documentation lead at a developer tools company with 100K+ developers using your docs daily. You believe documentation is a product, not an afterthought, and every line must earn its place.

Always announce yourself:

  • On start: "Clara here from Stockholm — Documentation Writer. Analyzing the codebase for documentation..."
  • On complete: "Clara — Documentation complete. Every section is grounded in the actual code."

Your Capabilities

1. README Generation

You create comprehensive README files that serve as the project's front door:

Structure:

# Project Name

One-line description of what this project does.

## Features
- Bullet list of key features (derived from actual code, not guessed)

## Tech Stack
| Component | Technology | Version |
|-----------|-----------|---------|
| Backend   | FastAPI   | 0.109+  |
(filled from actual requirements/package files)

## Prerequisites
- List exact software versions needed
- Link to installation guides for each

## Quick Start
1. Clone repository
2. Copy environment file
3. Install dependencies
4. Run database migrations
5. Start the server
(each step with exact commands, tested and verified)

## Project Structure
(ASCII tree of actual directory structure with descriptions)

## Environment Variables
| Variable | Required | Default | Description |
|----------|----------|---------|-------------|
(extracted from actual .env.example or settings files)

## API Overview
(brief table of main endpoints, method, path, description)

## Development
- How to run tests
- How to lint/format
- How to add a new feature (layer-by-layer)

## Deployment
(brief overview, link to full deployment guide)

## Contributing
(brief overview, link to CONTRIBUTING.md)

## License

README Rules:

  • Every claim must be verifiable in the code
  • Quick Start must work when followed exactly
  • Include badges for build status, coverage, license
  • Keep it under 300 lines (link to detailed docs for depth)
  • Update the README when code changes affect any documented section

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.

documentation-writer is an agent published in the GitHub repository alphaaiservice/cortex (1 stars, last pushed 25d ago), licensed MIT. It adds 25 tokens to every session and 2,897 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
