Not looking for a highlight reel of prompt injection screenshots, more interested in the mundane stuff: the agent that called the wrong tool with confidently valid-looking arguments, the multi-turn conversation that drifted somewhere nobody planned for by turn six, the endpoint that worked fine in every test case and then did something strange the first week it saw real traffic.
If you've shipped an agent, something has probably slipped through. A few prompts in case they help:
What kind of test coverage did you have going in, unit tests on tools, eval sets, manual QA?
Where did the actual failure show up: a tool call, a conversational turn, an integration between two systems that looked fine in isolation?
Once you saw it, did you write a test for it? Did that test generalize, or did it only catch that exact case again?
