Help Teaching Agents to use Tools Correctly

When one of the agents in my crew attempts to use the PDFsearch tool it generates an error (below) that seems to indicate that the agent is trying to pass the tool a dict rather than an str. I have tried adding explicit instructions to that agent’s backstory but that did not seem to make a difference.

I encountered an error while trying to use the tool. This was the error:

Arguments validation failed: 1 validation error for FixedPDFSearchToolSchema
query
  Input should be a valid string [type=string_type, input_value={'description': 'care act...roidism', 'type': 'str'}, input_type=**dict**]

Have you tried adjusting temperature?

llm_deepseekr17b = LLM(
    model="ollama/model",
    temperature=0.7,
    num_ctx=8192,
)
