Context: While building the sentience-sdk-playground/langchain-debugging/langgraph_demo.py (Esquire task), we observed a common failure mode: the agent “scrolls” but the UI doesn’t actually advance (no-op scroll due to overlays, nested scrollers, focus issues, etc.). This causes silent drift / infinite loops.

Goal: Add a first-class, deterministic scroll verification primitive so agents can assert “scroll had effect” with evidence, rather than trusting that the action executed.


Why a dedicated primitive?

  • “We called scroll” ≠ “the page advanced.”
  • Scroll failures are hard to diagnose without a before/after metric.
  • Verification should be backend-agnostic (Playwright, CDP, browser-use adapter).
