NewChecks now run on every tool call
Relay runs your AI agents in production. It plans, calls your tools, checks its own work, and shows you every step it took.
Tools with types
Describe a tool once in TypeScript. Relay checks every call against it before anything touches your systems, and refuses calls that do not fit.
export const refund = tool({
input: z.object({
order: z.string(),
amount: z.number().max(500),
}),
needsApproval: amount => amount > 100,
})
Checks before it replies
Write checks in plain words or code. Relay runs them on every answer and on every deploy, so a prompt change that breaks refunds never ships.
