Summary

In the Agents SDK Documentation for using dynamic_instructions while discussing the Agent, the following line is used:

def dynamic_instructions(
    context: RunContextWrapper[UserContext], agent: Agent[UserContext]
) -> str:
    return f"The user's name is {context.context.name}. Help them with their questions."

The line {context.context.name} is used, however, the UserContext dataclass shown does not contain a name attribute:

@dataclass
class UserContext:
    uid: str
    is_pro_user: bool

This leads to a runtime error:
AttributeError: 'UserContext' object has no attribute 'name'

Suggested Fixes

You can resolve this by either:
Adding name: str to the UserContext model, OR
Changing the instruction function to use one of the fields that do exist, like uid or is_pro_user.

Example fix:

def dynamic_instructions(context: RunContextWrapper[UserContext], agent: Agent[UserContext]) -> str:
    return f"User ID is {context.context.uid}. Help them accordingly."
