Re:Tell HN: Litellm 1.82.7 and 1.82.8 on PyPI are compromised on Wednesday March 25, 2026 @03:40PM (#47522157)
This is exactly what worries me about autonomous agents. A compromised package is bad. An agent that autonomously runs pip install with that package is a different problem. The attack surface moves with the agent.
Re:Show HN: ToolGuard – Pytest for AI agent tool calls on Tuesday March 17, 2026 @08:13PM (#47420122)
This is interesting because a lot of agent failures happen before any “reasoning” issue shows up.

If the tool boundary itself is unstable — wrong field names, wrong types, missing required values — the rest of the stack doesn’t really matter.

Deterministic fuzzing for tool calls seems especially useful because it gives you a way to test execution reliability without depending on another model in the loop.
