documentation-rules

A documentation rule for software projects.

In plain words
What is it for?
Use it when updating READMEs, quickstarts, specifications, setup instructions, deployment steps, or command examples.
Why use it?
It requires project documentation to stay synchronized after changes and to include practical setup, deployment, and usage guidance.

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-rules scanned grade A with 1 finding 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.

What it actually says

Documentation and Tools

  • After making changes, synchronize the README, quickstart, and other specifications.
  • Add convenient examples using curl and shell scripts.
  • Use connected MCP servers (e.g., context7) to search for libraries and utilities.
  • Maintain up-to-date documentation for deploying the project from scratch (including container builds, migrations, launching required utilities, data generation, and similar processes).
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.
