# What does this PR do?
This PR adds a `max_tokens` slider to playground tools page. I have
found that in some instances the llama stack server throws a 500 error
if the max_tokens value is not explicitly set in the agent's
`sampling_params`. This PR, uses the same implementation of the
`max_tokens` slider from the chat page, and includes it on the tools
page.
## Test Plan
1. Attempting to call a tool without these changes results in a `500:
Internal server error: An unexpected error occurred`.
2. Attempting to call a tool with these changes results in the expected
output.
