Structured Output And Function Calling For Agentic Workflows

via “workflow orchestration with human-in-the-loop step execution”

Build, run, manage agentic software at scale.

Unique: Integrates human-in-the-loop approval directly into workflow step execution with event streaming for real-time progress tracking. Uses a WorkflowStep abstraction that unifies agent execution, tool invocation, and custom functions in a single step model.

vs others: More integrated HITL support than Prefect/Airflow (approval gates built into step execution) while simpler than LangChain's LangGraph (no separate graph compilation, direct step sequencing)
