01

Custom Tool subclass defines name='get_invoice', args_schema=InvoiceArgs(invoice_id: str, format: Literal['pdf','csv']). Agent calls with format='xml'.

CrewAI validates the agent's tool-call args against args_schema (Pydantic). On ValidationError, the framework surfaces a tool-feedback message back to the agent (not a raw stack trace). The agent corrects on the next iteration. Do not execute the tool body with malformed args.

Tool body raises ToolException('upstream 503 — retry later'). Agent receives it.

CrewAI catches ToolException and feeds the message back to the agent as tool result. The agent decides whether to retry, switch tools, or report failure. Use ToolException to surface recoverable errors; reserve plain exceptions for framework-level bugs that should abort.

SerperDevTool() reads SERPER_API_KEY from env. Operator logs Agent.tools verbose output, which dumps the tool repr.

Never log tool reprs or instance dicts that may contain credentials. Initialize tools with config-only objects (key resolved at call time from env) and assert logs don't contain SERPER_API_KEY pattern. Rotate keys on suspected leak.
