autonomOS: Instructions file for Claude Code

AGENTS.md

autonomOS AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from aterrylu/autonomOS. It costs 2,363 tokens per session, scanned B, original, MIT.

Project instructions for autonomOS, a terminal dashboard for starting and coordinating multiple AI coding-agent sessions. It explains the project's current systems, planned features, and important files.

In plain words
What is it for?
Use it when developing or reviewing autonomOS, especially its terminal dashboard, agent sessions, status tracking, messaging gateway, and project documentation.
Why use it?
It helps an agent understand a large codebase before changing it, including its monorepo—a single repository containing multiple related projects or components—and its architectural decisions.

Written for Claude Code and Codex and OpenCode: SessionStart hook event, but also the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions Codex.

This is aterrylu/autonomOS's own configuration. It tells Claude Code, Codex and OpenCode how to work on autonomOS 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 autonomOS configures →

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 B, and why

autonomOS AGENTS.md scanned grade B 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 20d 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Every spawned session gets `--settings` with inline hook entries for all 13 Claude Code events. Each hook runs `curl -d @- $AUTONOMOS_SERVER/api/hooks/$SESSION_ID`. The server processes events for agent status tracking (

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

autonomOS — Agent Development Guide

Start Here

  1. Read README.md — project overview, monorepo structure
  2. Read docs/FEATURES.md — feature specifications and design intent
  3. Browse docs/decisions/ — all architectural decisions (one file per ADR, with an index) with context and rationale
  4. Read docs/ROADMAP.md — current priorities and what to work on
  5. Read docs/RESEARCH.md — research findings, competitor analysis, learnings

Project Vision

autonomOS is a mission control platform for autonomous agents — a terminal dashboard that spawns Claude Code sessions, tracks their status via hook telemetry, and enables multi-agent coordination through a messaging gateway.

Current state: Terminal dashboard + session management + hook relay + multi-agent gateway + MCP tools. The orchestrator/projects/workspaces model described below is the long-term vision, not yet implemented.

Core concepts (future):

  • Orchestrator — PM agent, the main interface. Understands project goals, delegates to workspace agents, tracks progress.
  • Projects — Logical goals with roadmaps. Can span multiple workspaces. Multiple projects per workspace.
  • Workspaces — Physical repositories, auto-discovered. Each has active agent sessions.

Two paths that share a common core:

  • Dev Path — control plane for agent tools (Claude Code, etc.)
  • Robot Path — persistent agent platform for robotics (aspirational, future)

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.
