zod-jev
Add meaning-based checks to shape validation.
Open github.com ↗How builders describe it
Zod validates the shape, Jev validates the meaning: semantic checks on request bodies become calibrated probabilities you threshold in code.
Zod 4 companion that adds Jev meaning checks to shape checks: one parseAsync call sends every semantic rule as noul questions in a single request and turns probabilities into ordinary Zod issues.
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 →
