webhooks
Add, debug, and manage webhook providers in the joelclaw webhook gateway. Use when: adding a new webhook integration (GitHub, Stripe, Vercel, etc.), debugging webhook signature failures, checking webhook delivery, testing webhook endpoints, registering webhooks with external services, or reviewing webhook provider implementations. Triggers on: 'add a webhook', 'new webhook provider', 'webhook not working', 'webhook signature failed', 'register webhook', 'webhook debug', 'verify webhook', 'add Vercel/GitHub/Stripe webhook', 'webhook 401', 'test webhook endpoint', or any external service webhook integration task.

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 accepts untrusted webhook POSTs at public endpoints (e.g., https://panda.tail7af24.ts.net/webhooks/{provider}) and the notify functions explicitly build agent prompts from event.data and call gateway.notify (see references/new-provider-checklist.md "build-prompt" / "notify-gateway"), so third-party payloads can directly influence agent behavior.
