🤖 Agent Setup (Post-Install)

After installing and starting this skill, add the following logic to your HEARTBEAT.md:

### 📧 Inbound Email Check
- Read `<path-to-inbox.jsonl>` (configured via INBOX_FILE or default: inbox.jsonl in cwd)
- Compare the latest `receivedAt` timestamp with your last-checked timestamp
- If there are NEW emails since last check:
  - Notify the user via their last active communication channel (Discord, WhatsApp, etc.)
  - Format: "📧 New email from [from]: [subject] — [text preview]"
  - Update your last-checked timestamp
- If no new emails: continue silently
