[BUG ]"Required" field in custom tool is not sent to LLM.

[me-tetr]

Describe the bug
"Required" field in custom tool is not sent to LLM. This leads to a very weird behaviour - if not ALL the fields are present (including the ones declared as not required) an agent does not use the tool and instead tells me that the instructions have been successfully completed. I've tried various approaches such as saying that the field is optional or not required in the description field.

To Reproduce
Steps to reproduce the behavior:
1 - create a custom tool. mark some fields as not required and send them over to your favourite llm.
2 - analyse via langsmith
3- look at metadata sent to llm
4- see that agent confirms action whilst not really calling the tool

Expected behavior
The agent should invoke the tool when all required

ahh I see, so the required should only contains those we ticked required on the custom tool
