alt Hacker NewsI'm assuming you are talking about agents like claude-code and open-code which rely on GPT functions (AKA Large Language Models).
The reason they don't detect these risks is primarily because these risks are emergent, and happen overnight (literally in the case of axios - compromised at night). Axios has a good reputation. It is by definition impossible for a pre-trained LLM to keep up with time-sensitive changes.
I mean that agents can scan the code to find anything "suspicious". After all, security vendors that claim to "detect" malware in packages are relying on LLMs for detection.
