Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install webhook-receiver-hardening

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent adds HMAC signature verification before any processing, stores already-seen event IDs to deduplicate, makes processing idempotent and handles provider retries. You get a duplicate storage strategy and a runbook for common incidents.
