Every tool call your agent makes, checked before it runs.
Open github.com ↗How builders describe it
Every tool call your agent makes, checked before it runs. A Claude Code plugin that uses TypeSafe AI's Jev to verify each pending tool call against the session plan, then allows it, asks you, or blocks it. Proof of concept.
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 131 safety & guardrails projects →
