jes
jes is an open-source guardrails library for checking agent inputs, retrieved content, tool calls, tool results, and responses for prompt injection, jailbreaks, and sensitive-data leaks.
Where it fits
jes is listed in Safety Guardrails (Safeguarding). Use its original project documentation to confirm the features and setup for your intended workflow.
Compare tools for constraining inputs, outputs and agent behavior. A guardrail needs a defined failure case and an observable response; a reassuring label alone cannot establish that a workflow is safe.
