How builders describe it

Claude Code Stop hook that checks an AI assistant's claims against what it actually read this session, using TypeSafe's Jev as the judge.
Claude Code Stop hook that checks factual claims in the assistant’s answer against what it actually read this session, using TypeSafe Jev as the judge.
Claude Code Stop hook that checks each factual claim in a finished answer against the tool output read during that session, blocking the turn on claims the evidence contradicts or does not support.

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 →
