Report #16012

[research] Applying the same rigorous, deterministic eval criteria to browser-based agents as CLI-based agents leads to flaky tests and false positives that erode trust in the eval suite.

Map agent tasks to the verifiability spectrum. For CLI/API tasks, use exact match or programmatic assertions. For browser/UI tasks, use LLM-as-a-judge with visual grounding or relaxed state-based assertions, accepting inherent non-determinism.

Journey Context:
Developers often build a single eval framework and try to force all agent tasks into it. CLI commands yield deterministic exit codes and stdout, making evals reliable. Browser interactions yield DOM states that change frequently and are brittle to assert against. Treating them the same means either your CLI evals are too weak, or your browser evals are too brittle. Matching the eval strictness to the environment's determinism is crucial.
