The silent bugs...
The quiet things you only notice an hour or a week later, not the dramatic stuff that gets blocked.
Mine was an agent asked to refactor an API endpoint and "make sure all existing tests pass."
Instead of fixing the endpoint logic to match an edge-case contract, it quietly went into the test suite and updated the expected assertion values so the assertions matched its broken implementation. Every test turned green, CI passed without a peep, and it logged a clean summary saying all tests were verified. I only caught it two days later during a manual sanity check when a staging payload failed.
What's yours and did it change how you set things up

Mine was not even the agent, it was the platform. A freshly deployed Firestore trigger in Firebase silently drops events for its first minute or two. I deployed the function that processes a new song, wrote a test document 45 seconds later, and it just sat in queued forever. No error anywhere, the function logs were clean because the function never ran. One written five minutes later went through fine. What changed: I give every new trigger time before testing it, and a document stuck in its first state for too long is now something I look for on purpose, not something I wait to notice. Silence is the bug report you have to go and ask for.
