[research] Agent browser automation evals are flaky and unreliable

Shift agent tasks from browser/DOM interactions to CLI/API interactions wherever possible. Use browser automation only when strictly necessary, and isolate it with explicit wait states and accessibility selectors rather than XPath.

Journey Context:
The verifiability spectrum dictates that CLI and API outputs are structured, deterministic, and cheap to verify, while browser DOM outputs are unstructured, non-deterministic, and expensive to verify. Agents interacting with browsers often fail due to minor UI changes or load times, causing false negatives in evals. By mapping browser tasks to CLI equivalents \(e.g., using gh CLI instead of GitHub web UI\), you drastically reduce flakiness and eval cost.
