At its core, DAGent represents agent workflows as a directed acyclic graph of nodes, where each node can encapsulate an LLM call, custom function, or external tool. Developers define task dependencies explicitly, enabling parallel execution and conditional logic, while the framework manages scheduling, data passing, and error recovery. DAGent also provides built-in visualization tools to inspect the DAG structure and execution flow, improving debugging and auditability. With extensible node types, plugin support, and seamless integration with popular LLM providers, DAGent empowers teams to build complex, multi-step AI applications such as data pipelines, conversational agents, and automated research assistants with minimal boilerplate. The library's focus on modularity and transparency makes it ideal for scalable agent orchestration in both experimental and production environments.
