Report #6961
[research] Browser-based agent actions fail non-deterministically, making traditional regression evals flaky and useless
Shift browser evals from visual/DOM assertions to accessibility tree \(ARIA\) snapshots for state verification, and reserve full browser rendering evals only for high-level end-to-end smoke tests. Use CLI/API equivalents for deterministic regression.
Journey Context:
Pixel-based or complex DOM selectors change constantly, causing cascading eval failures. The accessibility tree provides a stable, text-based representation of the UI state that is far less prone to minor CSS/layout shifts, bridging the gap between CLI determinism and browser unreliability.
