Description

Currently, when HandoffBuilder._apply_auto_tools creates handoff tools for specialist agents, it doesn't use the agent's description. This means the auto-generated handoff tools have generic descriptions like "Handoff to the refund_agent agent" instead of more informative descriptions based on the actual agent's purpose.

Current Behavior

In _handoff.py:1160, the code calls:

tool = _create_handoff_tool(alias)

This creates a handoff tool with a generic description.

Expected Behavior

When the target Executor is an AgentExecutor, the code should extract the agent's description from AgentExecutor._agent.description and pass it to _create_handoff_tool:

description = None
executor = specialists.get(exec_id)
if isinstance(executor, AgentExecutor):
    agent = getattr(executor, '_agent', None)
    description = getattr(agent, 'description', None)

tool = _create_handoff_tool(alias, description)

Benefits

• More informative handoff tool descriptions for LLMs
• Better alignment with agent's actual purpose
• Improved tool selection by the coordinator agent

Files to Modify

• python/packages/core/agent_framework/_workflows/_handoff.py: Update _apply_auto_tools method (around line 1149-1172)

Related Code

• _create_handoff_tool already accepts an optional description parameter (line 69)
• AgentExecutor._agent provides access to the wrapped agent (line 94 in _agent_executor.py)
