Report #56093

[research] Agent evals are flaky because browser-based or UI-based task verification is inherently unreliable

Shift tasks along the verifiability spectrum. For evals, prefer CLI/API verifiable endpoints \(exit codes, stdout, JSON responses\) over DOM/UI state. If browser interaction is required, inject test hooks or use deterministic accessibility tree snapshots instead of visual assertions.

Journey Context:
Evaluating agents that interact with browsers often relies on screenshot comparison or flaky DOM selectors, leading to high false-positive rates in eval suites. CLI and API tasks have deterministic ground truths. By designing eval tasks to use CLI equivalents or injecting test IDs, you drastically reduce eval flakiness and get true signal on agent logic.
