Introduced 2026-09-16 · score 0.98
HOW TO USE IT
When inspecting a page across browser interactions, run `agent-browser snapshot --delta` for an initial full snapshot and subsequent unchanged revisions or structural changes. Reuse refs for surviving DOM elements across same-document updates; run `agent-browser snapshot --delta --full` to refresh the baseline and take a fresh snapshot after navigation or to observe page changes.
