In plain words
What is it for?
Finding Rust backend, Solid.js frontend, terminal, editor, and session-management code; and working with the project’s Tauri, Tokio, TypeScript, bun, and Cargo setup.
Why use it?
They help the coding agent understand the application’s architecture and follow its language, platform, package-manager, and code-organization rules.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md; mentions Codex.

This is andremonaco/raum's own configuration. It tells Codex and OpenCode how to work on raum itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything raum configures →

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 C, and why

raum AGENTS.md scanned grade C 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 1mo 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.

What is raum?

raum is a lightning-fast, recoverable terminal orchestrator for AI agent harnesses (Claude Code, Codex, OpenCode). Every pseudo-terminal runs inside a tmux session (-L raum socket) so the app can crash-restart without killing agents. Built with Tauri v2 (Rust backend), Solid.js (frontend), and xterm.js (terminal renderer). Target platforms: macOS and Linux.

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.
