What is agent-os CLAUDE.md?

Project guidance for Agent OS, a local-first workspace that combines project conversations, saved notes, task coordination, and controlled coding-agent execution.

Working on Agent OS while following its architecture, project documentation, local storage approach, and rules for handing work to coding agents.

It gives coding agents the project’s mission, structure, and operating principles so their changes fit the system’s intended design.

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.

Model	Per session	Once invoked
Fable 5.1	$0.02447	$0.02447
Opus 5.5	$0.00979	$0.00979
Sonnet 5.5	$0.00489	$0.00489

Security

Grade C, and why

agent-os CLAUDE.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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

Operating guide for Claude Code and any other coding agent working on this repository. This file is intentionally short, stable, and phase-independent. For the system's shape (files, pipelines, invariants) read ARCHITECTURE.md; for the project's history and status read ROADMAP.md; for long-term direction read BLUEPRINT.md. The public README.md is a landing page, not a status file.

1. Project Mission

Agent OS is a lightweight local-first project cockpit — a small Agent Operating System for managing multiple long-term projects through a single web chat surface. It combines project-scoped conversations, structured markdown memory, an orchestration layer, and a bounded execution layer that hands work to a Coding Agent inside a sandboxed workspace, then delivers the result through audited Git/GitHub and deployment contracts. The goal is not a general-purpose assistant or a heavyweight agent platform; it is a clear, controllable place for a single builder to plan, decide, and execute project work.

2. Core Architecture Principles

Local-first. Filesystem + SQLite + FastAPI + React. No cloud services, no queues, no external infra dependencies for the core.
Project isolation. Each project has its own conversations, memory files, and execution workspace. Crossings are deliberate and bounded.
Structured markdown memory. Important state lives in readable, editable .md files, not buried in chat history.
Main agent = brain. Planner / memory steward / orchestrator. Does not edit code under repo/.
Coding Agent = hands. Bounded executor inside the project's execution_workspaces/{project_id}/repo/. Does not edit project memory or other projects' workspaces.
All execution goes through ProjectSandbox + ToolRuntime. No raw os / pathlib access to repo paths, no raw subprocess. Every tool call routes through resolve_repo_path() / resolve_under() or validate_command().

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.
