What is Operator-Use CLAUDE.md?

Repository instructions for Operator, a Python framework that runs stateful AI agents across multiple providers, tools, sessions, extensions, and messaging channels. They describe its four main layers and where the code for each layer lives.

Navigating the repository, understanding the architecture, and working on inference, sessions, extensions, automation, scheduling, or connections such as Telegram, Slack, WebSocket, and email.

They give an agent a map of the system and its boundaries, making it easier to find the right code and preserve the separation between engine, agent, runtime, and gateway responsibilities.

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	$0.01675	$0.01675
Opus 5.5	$0.00670	$0.00670

Security

Grade A, and why

Operator-Use 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 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.

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.

Project Overview

Operator is a stateful Python AI agent harness. It wraps a multi-provider LLM inference layer with session persistence, context compaction, an extension/package system, sandbox enforcement, browser/computer automation, and a gateway that connects the agent to multiple messaging channels simultaneously (Telegram, Discord, Slack, WebSocket, Email, Twitch, stdio).

Four layers build on each other:

Engine (operator_use/engine/) — raw LLM streaming loop, tool execution, abort signal. No knowledge of sessions or extensions.
Agent (operator_use/agent/) — turn orchestration, retry, compaction scheduling, extension event fan-out. Implements ExtensionContext.
Runtime (operator_use/runtime/) — session lifecycle, slash-command dispatch, gateway/cron/subagent wiring.
Gateway (operator_use/gateway/) — channel adapters, async message bus, per-session agent routing.
