agent-email-inbox

Use when building any system where email content triggers actions — AI agent inboxes, automated support handlers, email-to-task pipelines, or any workflow processing untrusted inbound email. Always use this skill when the user wants to receive emails and act on them programmatically, even if they don't mention "agent" — the skill contains critical security patterns (sender allowlists, content filtering, sandboxed processing) that prevent untrusted email from controlling your system. Real-time responsiveness — React to emails within seconds, not minutes No polling overhead — No cron jobs checking "any new mail?" repeatedly

1. Ask the user for their email address — You need a real email address to send test emails to. Ask the user and wait for their response before proceeding. Before You Start: Account & API Key Setup If your human has an existing Resend account with other projects, create a domain-scoped API key: 2. Create a scoped API key: Dashboard → API Keys → Create API Key → "Sending access" → select only the agent's domain | 5 | Human-in-the-Loop | Require human approval for untrusted actions | Maximum security, adds latency |
