Report #61107

[research] Agent evals are flaky because they rely on asserting exact states in non-deterministic environments like web browsers

Map your agent's tasks to the verifiability spectrum and design evals accordingly. For CLI/DB tasks, use exact state assertions \(exit codes, DB queries\). For browser tasks, use LLM-as-a-judge or accessibility-tree assertions, and accept probabilistic pass rates.

Journey Context:
Treating all evals the same leads to either false negatives \(browser evals failing on minor DOM changes\) or false positives \(CLI evals not checking exact outputs\). CLI actions are deterministic and cheap to verify; browser actions are inherently noisy. You must decouple the verifiability strategy from the agent's execution environment.
