A prompt meant to sharpen the assistant's judgment actually made it worse
We tried giving Righthand explicit instructions on how to weigh the stakes of a decision before acting, expecting better judgment when situations were unclear. It backfired. The version with the new instructions made worse decisions than the version without them, even though the idea had looked promising in early spot checks.

Experimental design
The treatment prompt gave the agent a framework for distinguishing lower-stakes tasks from higher-stakes tasks.
The intended behavior was faster action in safe situations and more clarification in risky situations.
Observed result
The treatment performed ten percentage points worse than the control condition.
The failure was concentrated in transfer cases where the agent needed to generalize from examples of risky behavior.
Interpretive limits
This is a product experiment rather than a leaderboard benchmark.
The result is useful as evidence against a plausible prompt change, not as a general claim about model capability.
