### Summary
This pull request fixes [issue
#892](https://github.com/openai/openai-agents-python/issues/892) by
adding a missing docstring to the `fetch_user_age` tool function in
`docs/context.md`.
### Problem
Many non-OpenAI LLMs (such as Claude, Gemini, Mistral, etc.) are unable
to use the `fetch_user_age` function because it lacks a docstring. As a
result, they return responses like:
> "I cannot determine the user's age because the available tools lack
the ability to fetch user-specific information."
### Changes Made
- Added a one-line docstring to the `fetch_user_age` function
- Improved return statement to match expected tool output
```python
@function_tool
async def fetch_user_age(wrapper: RunContextWrapper[UserInfo]) -> str:
"""Fetch the age of the user. Call this function to get user's age information."""
return f"The user {wrapper.context.name} is 47 years old"
