Flow is an orchestration framework for designing and executing complex workflows using autonomous agents powered by large language models. It serves as a toolkit for constructing agentic pipelines and a runtime for managing agent lifecycles, session states, and tool execution.
The project is distinguished by its support for hierarchical swarm management, where director agents decompose large projects into smaller tasks for specialized worker agents. It enables multiple coordination patterns, including sequential linear pipelines and concurrent execution where agents analyze tasks from different perspectives simultaneously.
The framework covers a broad range of capabilities including custom tool definition and skill assignment, event-driven lifecycle interception, and tool execution restrictions to block unauthorized operations. It also includes infrastructure utilities for state-isolated session management, socket-activation port binding for privileged ports, and connection-pooled local traffic routing for HTTP and WebSocket requests.
A command-line interface is provided to execute and visualize the interactions of autonomous agent swarms.
