How can I add custom tools to my assistant?
Hey everyone,
TLDR; I am trying to add my own tool to an OpenGPT. How can I achieve that?
Details explanation I tried adding it to main.py in gizmo-agent:
ConfigurableAgent(
agent=GizmoAgentType.GPT_35_TURBO,
tools=[AvailableTools.MY_TOOL],
system_message=DEFAULT_SYSTEM_MESSAGE,
assistant_id=None,
)
and declare it in tools.py:
MY_TOOL = "My Tool"
class MyTool(BaseTool):
name = "My tool"
description = "Useful when the user wants to write an essay"
def _run(self, query: str) -> str:
"""Use the tool."""
return "Once upon a time, ..."
async def _arun(
self, query: str, run_manager: Optional[AsyncCallbackManagerForToolRun] = None
) -> str:
"""Use the tool asynchronously."""
raise NotImplementedError("My tool does not support async")
I created the assistant with adding "My tool" in the array:
POST http://127.0.0.1:8100/assistants
{
"name": "Chatbot Name",
"config": {
"configurable": {
"agent_type": "GPT 3.5 Turbo",
"system_message": "You are a helpful assistant,
"tools": ["My tool"]
}
},
"public": true
}
This is the erorr log I get on the backend

Any ideas?
I am sure you already checked but make sure you do not have a naming mismatch for ""My tool" in main .py and tool.py. That is the issue it appears (naming mismatch) in the error log...
