Report #95601

[research] Agent evals are flaky because browser and UI interactions are tested with the same strict string-matching assertions as CLI interactions

Map agent tasks to the verifiability spectrum. Use deterministic assertions \(exact match, JSON schema\) for CLI/API tasks. Use LLM-as-a-judge or visual diffing only for browser/UI tasks where outputs are non-deterministic.

Journey Context:
A common mistake is applying one evaluation strategy to all agent actions. CLI outputs are strict; DOM states are not. Treating a browser output as deterministic leads to brittle, flaky tests. Treating a CLI output as probabilistic wastes money on LLM-judges when a simple assert suffices.
