- Added validation to ensure all parameters listed in `exclude_args` exist in the function.
- Ensured parameters in `exclude_args` have default values to avoid runtime errors.
- Added test.
This introduces an `exclude_args` parameter to omit specified arguments
(such as `state`, `memory`, etc.).
It will exclude the mentioned args from the schema sent to the LLM and still allow them
to be passed when the tool is called.
This doesn't come with the MCP protocol but can be useful in many use cases.
