🔒 Is jev-browser safe to install? View the security audit →
jev-browser Browser automation where an LLM plans and Jev decides. Unofficial project, not affiliated with TypeSafe. It calls the TypeSafe System One API with your own API key. The calling LLM (Claude, via MCP) says what outcome it wants, one step at a time, and hands over any text to type. For each round of a step, code describes the page. Then one 300 ms Typesafe System One request asks Jev several questions at once: which element, which action, which value, and is the step done / blocked / showing an error / about to do something irreversible. Playwright performs the action. The LLM never reads page snapshots unless it chooses to take over. https://github.com/user-attachments/assets/2e688df9-4985-4854-8ebe-ba97c9d13d68 Jev only answers with probability distributions: yes/no (noul

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.
