LangGraph provides a flexible multi-agent system built on directed graphs, where each node represents an AI agent specialized in tasks like code synthesis, review, debugging, or chat. Users define workflows in JSON or YAML, specifying agent roles and communication paths. LangGraph manages task distribution, message routing, and error handling across agents. It supports plugging into various LLM APIs, extensible custom agents, and visualization of execution flows. With CLI and API access, LangGraph simplifies building complex automated pipelines for software development, from initial code generation to continuous testing and interactive developer assistance.

Multi-Agent Coordination provides a lightweight API to define AI agents, register them with a central coordinator, and dispatch tasks for collaborative problem solving. It handles message routing, concurrency control, and result aggregation. Developers can plug in custom agent behaviors, extend communication channels, and monitor interactions through built-in logging and hooks. This framework simplifies the development of distributed AI workflows, where each agent specializes in a subtask and the coordinator ensures smooth collaboration.
