Description

The max_retries parameter from the ToolOutput class is never used. Initialization happens via the OutputToolset.build class method that returns an OutputToolset object with max_retries set to the default value of 1.

Minimal, Reproducible Example

import os
os.environ["OPENAI_API_KEY"] = "XXXXX"

from pydantic import BaseModel
from pydantic_ai import Agent
from pydantic_ai.output import ToolOutput


class Foo(BaseModel):
    bar: str


agent = Agent(
    "openai:gpt-5.2",
    
    output_type=ToolOutput(Foo, max_retries=3)
)

print(agent.toolsets[0].output_schema.toolset.max_retries)
#> 1
