SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Managing inbound emails for AI agents securely is complex and risky; this skill provides a structured approach to receiving, validating, and routing emails to an agent while preventing prompt injection and data leakage.

Core Features & Use Cases

  • Inbound email integration: configure a dedicated inbox using Resend or your own domain and set up webhook delivery to your agent.
  • Real-time processing with webhooks: verify signatures and route email data to the agent instantly.
  • Development-friendly tunneling: expose local webhook endpoints via ngrok or Cloudflare tunnels for testing and debugging.
  • Security-first routing: implement prompt-injection protections, sender allowlists, and capability restrictions for external emails.

Quick Start

  • Set up an inbound address with Resend or your own domain to receive emails for your AI agent.
  • Implement a webhook endpoint to process inbound emails and verify webhook signatures.
  • Use ngrok or Cloudflare to expose your local server for webhook delivery during development.
  • Configure basic security measures (allowlists, rate limits, and content sanitization) before connecting to your agent.
