I think this article demonstrates a broader problem with constraint following in LLMs. Agents often satisfy the most obvious and easily verifiable part of a task, but lose track of the constraint that actually determines success.

Testing makes this especially clear: “use fuzzing” turns into generating random bytes, and “use formal verification” into proving a property that isn’t particularly useful. Formally, the technique is applied, but its actual purpose is lost.

This may also explain why different testing techniques produce similar results: the problem may be less about knowing a particular technique and more about the agent’s ability to keep its actual goal as the primary constraint.
