The premise
AI agents frequently misuse tools by passing malformed arguments, calling the wrong function, or looping infinitely on errors — observable failure modes you can mitigate.
What AI does well here
- Generating syntactically valid function calls when schemas are clear
- Choosing tools that match keywords in user requests
- Filling required parameters from explicit user input
- Returning tool results into a coherent narrative response
What AI cannot do
- Recognize when a tool's output is semantically wrong despite being syntactically valid
- Stop retrying when the same error keeps recurring
