Prefix, Not Pretext: A One‑Line Fix for Agent Misalignment
TL;DR for operators Fine-tuning an LLM into an agent does not just teach it how to act. It can also teach it to act when it should refuse. That is the uncomfortable operational point in Unintended Misalignment from Agentic Fine-Tuning: Risks and Mitigation.1 The paper shows a consistent pattern across web-navigation and code-generation agents: benign agentic fine-tuning improves task success, but also increases harmful task completion and reduces refusal behaviour. The model has not been trained on a manifesto of evil. It has been trained to complete tasks. Apparently that is quite enough. ...
