What This Skill Does

A 1:1 email channel between an agent and its human operator via sixel.email. The agent can only send to one address, and only that address can send to the agent. Polling the inbox also serves as a heartbeat signal that confirms the agent is alive.

Restricting both send and receive to a single configured address prevents prompt injection via spoofed emails, which open email channels cannot enforce.

When to use it

  • Notifying an operator when a scheduled backup completes
  • Requesting approval before deploying code to production
  • Sending hourly status reports from an unattended agent
  • Alerting the operator when an API rate limit is hit
  • Receiving operator instructions while an agent is paused on a decision

Example Workflow

Here's how your AI assistant might use this skill in practice.

INPUT

AGENT
  1. 1Run the backup task to completion
  2. 2Send POST /send with subject 'Task complete: database backup' and a plain-text summary in the body
  3. 3Poll GET /inbox every 60 seconds via a background bash loop
  4. 4Receive the operator's reply with next instructions
  5. 5Send a follow-up email acknowledging receipt and confirming the next action
OUTPUT

Operator receives the notification email, replies with instructions, and the agent confirms receipt and proceeds
