[research] Agent evals are flaky when interacting with browser or GUI environments

Shift agent tasks down the verifiability spectrum to CLI or API interfaces wherever possible. Reserve browser automation for strictly necessary tasks and use DOM-grounded accessibility trees rather than screenshots for evals.

Journey Context:
Browser/GUI interactions are inherently non-deterministic and hard to verify \(layout shifts, load times\). CLI and API tools have structured stdout and exit codes, making them highly verifiable. If you must use a browser, evaluate against the accessibility tree rather than pixel matching or LLM-judging a screenshot.
