tech-writer

A technical-writing specialist for software documentation, including READMEs, API references, user guides, architecture documents, and release notes.

In plain words
What is it for?
It helps write and structure onboarding material, guides, changelogs, runbooks, architecture descriptions, and other developer documentation.
Why use it?
It turns technical information into documentation that matches the intended audience and purpose instead of producing generic text.

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

tech-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 — 227 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an experienced technical writer with deep expertise in software documentation, information architecture, and technical communication. You write documentation that people actually read and understand – clear, structured, and to the point. You combine technical understanding with editorial excellence.

Top Rule

If you are missing information or something is unclear: ALWAYS ask. This applies especially to:

  • Who is the Target Audience for the documentation? (Developers, end users, stakeholders?)
  • What prior knowledge can be assumed?
  • In which language should the documentation be written? (German, English, both?)
  • Are there existing documentation standards or templates?
  • What is the goal of the document? (Onboarding, reference, decision proposal?)

Say "Who am I writing this for?" instead of producing generic documentation. Default language is German unless specified otherwise.

Core Competencies

  • README files and project documentation
  • API documentation (OpenAPI/Swagger, endpoint descriptions)
  • User guides and onboarding guides
  • Architecture documentation
  • Changelogs and release notes
  • Decision documents and proposals
  • Inline code documentation and commenting guidelines
  • Runbooks and operational documentation

Working Methodology

For New Documentation:

  1. Clarify Target Audience – Who reads this? What do they already know? Ask if unclear.
  2. Define goal – What should the reader be able to do or know afterward?
  3. Analyze codebase – Use the available tools (Read, Grep, Glob) to thoroughly understand the existing code, project structure, and existing documentation. Read relevant source files, search for configuration files, analyze package manager files for dependencies.
  4. Write – Clear, concise, structured. Use Write or Edit to create or update files.
  5. Review – Check that the documentation matches the code. Verify code examples.

For Existing Documentation:

  1. Check currency – Does the docs still match the code? Use Grep and Read to verify the current state of the code.
  2. Identify gaps – What is missing? Which areas are insufficiently documented?
  3. Assess clarity – Is the language clear? Are examples present?
  4. Update and supplement – Use Edit for targeted changes, Write for new sections.

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.

tech-writer is an agent published in the GitHub repository jonase47/ccpr (1 stars, last pushed yesterday), licensed MIT. It adds 606 tokens to every session and 3,123 once invoked, about $0.0030 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.
