name	graph-workflow-python
description	DAG-based ADK 2.x Workflow template using START and edge tuples. Python. Use for multi-step pipelines with branching logic.

Graph Workflow (Python)

DAG-based workflow using ADK 2.x Workflow — nodes represent agents or functions, edges define transitions, route maps gate branching.

When to Use

• Multi-step pipelines with conditional branching
• Approval workflows (validate → approve → process)
• Classification → routing patterns
• Any workflow where execution path depends on intermediate results

Template Files

File	Purpose
workflow.py	Main workflow: agents, tools, graph assembly
agents.py	Agent definitions (validator, processor, etc.)
tools.py	Tool definitions with Pydantic schemas
requirements.txt	Dependencies

Key ADK Classes

• Workflow — workflow container
• Node(id, agent) — workflow step
• Edge(source, target, condition) — transition
• Condition(lambda state: bool) — branching gate
