Collecting real cases of AI agents reporting 'done' with empty or wrong results

A Reddit user is collecting real-world cases where AI agents reported success while the underlying result was empty, stale or wrong: parsers matching nothing, changed source shapes, writes that never landed, pages that looked alive but were empty.

The poster discloses they are prototyping an early-warning tool in this area (not selling anything), and asks for the case, time-to-detection, how it was discovered, and what checks people now run. False-success failures are a genuine pain point in agent engineering.
