Jev Permission Gate

A Claude Code plugin that replaces the built-in auto-mode permission classifier with Jev, deciding tool calls in about half the time while agreeing with the original on the calls it handles.

Highlights

  • Swaps Claude Code's auto-mode permission classifier for Jev to gate tool calls.
  • Reports a 329 ms to 164 ms median latency drop, roughly 2x faster, at equivalent decision quality.
  • The built-in classifier still runs in parallel, so handoffs stay fast when Jev is uncertain.
  • MIT-licensed TypeScript plugin, installed through the author's Claude plugin marketplace.

Watch out

It is a latency improvement inside auto mode, not a security boundary, and it needs its own TypeSafe key; thresholds and coverage should be reviewed before relying on it.

Chrome MV3 extension plus a local MCP server exposing 50 browser tools; its chrome_act_toward_goal micro-loop uses TypeSafe Jev System One or a local decider to pick the next action on an 85%+ pruned, Shadow-DOM-pierced DOM tree, dispatching trusted CDP events in logged-in Chrome without stealing focus.

MCP server that lets Claude Code, Cursor and other clients drive Chrome over the DevTools Protocol, exposing an accessibility-tree menu of stable refs. Its example Jev loop has Jev pick browser actions from that menu, and the README reports about a third fewer tokens and a quarter fewer tool calls in a blind benchmark.
