Agent demos are easy to like because nothing important is attached to them. A demo agent can call the wrong tool, misread a JSON response, or politely announce that an API failure is actually a useful answer. Everyone smiles, someone says “interesting,” and the team adds another item to the backlog. Very innovative. Very safe. Very far from production. ...
The expensive part of an AI agent making things up is not always the sentence it writes. Sometimes it is the API call it sends. A chatbot can hallucinate a policy clause and embarrass itself. An agent can hallucinate a function call and move money, query the wrong data, calculate the wrong dose, bypass an audit trail, or quietly pretend it used a tool when it actually guessed. That is a different species of failure. The output may still look tidy. The JSON may still parse. The function name may even exist. The problem is that the agent has selected the wrong action in a system that treats actions as real. ...
When Tools Think Before Tokens: What TxAgent Teaches Us About Safe Agentic AI Tools are supposed to make AI safer. That is the sales pitch, anyway. Give the model access to curated biomedical databases, let it call APIs instead of hallucinating from memory, and clinical reasoning suddenly becomes more grounded. Less improvisation, more evidence. Less theatrical confidence, more traceable work. ...
TL;DR for operators ContextAgent is not interesting because it imagines an assistant that talks before the user does. We already have enough software that talks before anyone asks. The interesting part is more disciplined: it tries to decide when an assistant should remain silent, when it should intervene, and which external tools it should call when intervention is justified. ...
