## When it is useful

Writing any webhook handler — verify first, parse second, handle idempotently; retries and Express/Next.js/FastAPI raw-body gotchas.

## The Catch

Skills MIT; patterns are vendor-neutral and work without a Hookdeck account — but the skill nudges toward Hookdeck Event Gateway, whose Developer plan is capped at 10k events/mo, 3-day retention, 1 user (Team $39/mo+). Upstream skill id is `webhook-handler-patterns`.
