maat CLAUDE.md

maat CLAUDE.md is an instructions file for coding agents from getmaat/maat. It costs 168 tokens per session, scanned A, a copy of maat copilot-instructions.md, Apache-2.0.

Project instructions for the Ma'at codebase when using Claude Code, Anthropic's command-line coding assistant. They require reading the documentation index before changing code.

In plain words
What is it for?
Use them when modifying Ma'at: start with docs/llms.txt, read relevant documentation, and update matching documents in the same change.
Why use it?
They help keep code changes aligned with the repository's documented rules and ensure affected documentation is updated with the code.

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

maat CLAUDE.md 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 4d 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

89% identical to maat copilot-instructions.md — 8 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

Claude Code — project instructions

This project uses Ma'at. The single source of truth for agent instructions is AGENTS.md at the repository root. Read it first.

Before changing code, read the relevant documentation in docs/ — start from docs/llms.txt, which indexes every doc.

After changing code, update the matching doc(s) in the same change, as described in AGENTS.md under "Documentation update protocol". Treat docs as part of the diff, not an afterthought.

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.
