Maestro CLAUDE.md is an instructions file for coding agents from RunMaestro/Maestro. It costs 22,742 tokens per session, scanned A, original, AGPL-3.0.

A set of instructions for Claude Code projects using RunMaestro or Maestro, including how to maintain a claude.md file and a documentation index.

In plain words
What is it for?
Use it to guide project documentation, code reuse, and agent behavior before adding code.
Why use it?
It helps the agent check existing utilities and shared functions before writing new code, reducing duplicate implementations.

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

Maestro CLAUDE.md scanned grade A with 2 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- Heads-up on this dev setup: the dev server often runs with `DISABLE_HMR=1`, so live edits will NOT hot-reload. A full page reload only picks up new code if the vite process was started **after** the edit hit disk. Veri

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

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.
