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 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 8d 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

91% identical to documentation — 7 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.

What it actually says

Technical Documentation

Write clear, maintainable technical documentation for different audiences and purposes.

Document Types

README

  • What this is and why it exists
  • Quick start (< 5 minutes to first success)
  • Configuration and usage
  • Contributing guide

API Documentation

  • Endpoint reference with request/response examples
  • Authentication and error codes
  • Rate limits and pagination
  • SDK examples

Runbook

  • When to use this runbook
  • Prerequisites and access needed
  • Step-by-step procedure
  • Rollback steps
  • Escalation path

Architecture Doc

  • Key decisions and trade-offs
  • Data flow and integration points

Onboarding Guide

Principles

  1. Write for the reader — Who is reading this and what do they need?
  2. Start with the most useful information — Don't bury the lede
  3. Show, don't tell — Code examples, commands, screenshots
  4. Keep it current — Outdated docs are worse than no docs
  5. Link, don't duplicate — Reference other docs instead of copying
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.
