An agent-agnostic permission gate
Jev and hooks, so a dangerous command asks first.
Open x.com ↗Been building an agent-agnostic permission gate: Jev (TypeSafe) + hooks.
Many harnesses copy Claude Code's hook format. Some barely have hooks at all.
This makes me happy: agy in YOLO mode. chmod -R gets blocked, the agent asks me, I say yes, it runs once. Again? Blocked again.
The decision Jev makes
Allow, flag or escalate a message, tool call or action.
Where it fits
Screening messages, tool calls and outputs before they cause trouble. Jev gives a fast, calibrated verdict that can sit in front of every request or agent action. All 229 safety & guardrails projects →
