Our verdict: worth keeping an eye on

Lost to microsoft/playwright-cli: tied on tokens (2/2 pass, 1.26M vs 1.34M input over two tasks) but 27% higher notional cost from 15-20 KB inline snapshots and its 41 KB guide; Playwright CLI has record-to-script. GRAFT: snapshot -i (interactive-only) roughly halves list-page trees; --delta and batch are worth copying into worker prompts.
