Show HN: AgentUQ, a token-logprob runtime gate for LLM agents

I built this over the weekend because agent systems seem to jump from static guardrails to much heavier judge-style loops, with not much in between. AgentUQ uses provider logprobs to localize brittle action-bearing spans in an agent step and route actions like continue, retry, verify, ask for confirmation, or block. The claim is intentionally narrow. It isn’t trying to determine truth. I know uncertainty work can feel theoretical, so I wanted to test whether a smaller operational use of it could be useful in practice.
