The Calls are Coming from Inside the Model: Investigating Probe-based Detection of Tool-Calling Errors in LLMs
A new arXiv preprint (2608.27750v1) finds that linear probes on hidden states can effectively detect incorrect tool-calling errors in large language models, tested across 18 tool-calling LLMs on the B…
