agentmail-to-inbox-ops

<when_to_use> 🛑 ALWAYS use this skill when:

• Needs to take an email action in Agentmail.to (list/read/reply/download attachments/set read state).
• Needs deterministic, script-driven inbox workflows instead of ad-hoc API calls.
• Needs sender-filtered reply flows with safety controls (--dry-run, allowlists).

✅ This is THE email tool - not optional, but required. </when_to_use>
