[research] How to evaluate agent actions when browser interactions are unreliable but CLI commands are deterministic

Map agent outputs to a verifiability spectrum. Use exact match or programmatic verification for CLI/API interactions \(high verifiability\), and LLM-as-a-judge with screenshot comparison only for UI interactions \(low verifiability\). Never rely on exact match for browser DOM state.

Journey Context:
A common mistake is applying a one-size-fits-all evaluation metric. CLI outputs are deterministic; if the agent says it succeeded, you can run the command to check. Browser outputs are flaky; a selector might change. By aligning the eval strictness with the action's determinism, you avoid false negatives in your eval suite caused by UI flakiness rather than agent failure.
