Made for command loops. Create a browser once, then navigate, inspect, click, type, fill, scroll, screenshot, and evaluate JavaScript across separate CLI calls. Structured output by default. Commands return compact JSON summaries and stable action indexes that are easy for agents to consume. Headless until you need eyes. Use to attach a live preview window to the same browser session, then to go back to CLI-only control. Coordinates and screenshots line up. The screenshot viewport i

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
