documentation

A guide for writing and maintaining technical documents such as READMEs, API references, architecture notes, runbooks, and onboarding guides.

In plain words
What is it for?
Use it to document setup, configuration, APIs, system design, operating procedures, contribution steps, and onboarding tasks.
Why use it?
It helps turn system knowledge into documents that different readers can follow and keep current.

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 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.

Origin

This is a copy

97% identical to documentation — 1 line 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

  • Context and goals
  • High-level design with diagrams
  • Key decisions and trade-offs
  • Data flow and integration points

Onboarding Guide

  • Environment setup
  • Key systems and how they connect
  • Common tasks with walkthroughs
  • Who to ask for what

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
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
