Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install webhook-reliability-subagent

First time: connect the CLI with

npx --yes palatekit@latest login

This subagent checks signatures against the raw body, makes handlers idempotent, plans retries with backoff and a dead-letter queue for failed events. It also designs outbound webhooks for your own API. The main agent hands it work when a third-party service sends events or when you emit them.
