event-gateway
Comprehensive guide to the Hookdeck Event Gateway for receiving, routing, and delivering webhooks and events. Covers setup, connections, authentication, local development, monitoring, and API automation. Use when receiving webhooks, setting up webhook endpoints, testing webhooks locally, configuring webhook relay or event queue, event routing, webhook retry, webhook monitoring, third-party routing, asynchronous APIs, or local webhook development. For provider webhooks (Stripe, Shopify, Chargebee, GitHub, etc.), use together with the matching skill from hookdeck/webhook-skills; do not only parse JSON — use provider SDK verification and event construction (e.g. Stripe constructEvent).

2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.90). The skill explicitly ingests and expects the agent to read and act on inbound webhooks from external providers (e.g., "Receive webhooks" / Source URL https://hkdk.events/... and provider examples like Stripe, Shopify, GitHub) and instructs agents to inspect those requests/events via CLI/API (see references/03-listen.md and references/04-iterate.md with `hookdeck gateway request list/get`, CLI TUI, and replay flows), so untrusted, user-generated third‑party content is consumed and can materially influence subsequent actions.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 1.00). The skill explicitly instructs agents to run "npx skills add hookdeck/webhook-skills --skill …" and to use the provider skill from https://github.com/hookdeck/webhook-skills at runtime, which fetches and installs remote code that the skill requires and will be executed for provider verification, so this is a runtime external dependency that executes remote code.
