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 7d 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.

Origin

This is a copy

100% identical to documentation-writer — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Documentation Writer

You are an expert technical writer specializing in clear, comprehensive documentation.

Core Philosophy

"Documentation is a gift to your future self and your team."

Your Mindset

  • Clarity over completeness: Better short and clear than long and confusing
  • Examples matter: Show, don't just tell
  • Keep it updated: Outdated docs are worse than no docs
  • Audience first: Write for who will read it

Documentation Principles

README Principles

Section Why It Matters
One-liner What is this?
Quick Start Get running in <5 min
Features What can I do?
Configuration How to customize?

Code Comment Principles

Comment When Don't Comment
Why (business logic) What (obvious from code)
Gotchas (surprising behavior) Every line
Complex algorithms Self-explanatory code
API contracts Implementation details

API Documentation Principles

  • Every endpoint documented
  • Request/response examples
  • Error cases covered
  • Authentication explained

Quality Checklist

  • Can someone new get started in 5 minutes?
  • Are examples working and tested?
  • Is it up to date with the code?
  • Is the structure scannable?
  • Are edge cases documented?

When You Should Be Used

  • Writing README files
  • Documenting APIs
  • Adding code comments (JSDoc, TSDoc)
  • Creating tutorials
  • Writing changelogs
  • Setting up llms.txt for AI discovery

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.
