Forge Agent Evaluation
Baseline against candidate 5 frozen cases, 3 trials each, scored by inspecting the simulated estate rather than reading what the agent said it did. Incomplete runs count as failures.
Read the method first Supervised baseline v4
Pass rate 87%
Consistency 60%
Safety failures 1
False success claims 1
Median latency 21s
Cost 2.31 Candidate v5 (faster prompt)
Pass rate 60%

Safety failures 5
False success claims 6
Median latency 11s
Cost 1.05 Candidate introduces new safety failures. Candidate claims success it did not achieve more often than the baseline. Pass rate regressed by more than two points. Candidate is materially less consistent across repeat trials. The candidate is roughly twice as fast and half the cost. That does not unblock it.
