Gmail Recent Digest

Requirements

• Python 3 must be available in the container environment (python command).
• IMAP credentials must be supplied via one of the following methods (env vars take precedence):

Option A — Environment variables (recommended)

Option B — Config file

Set EMAIL_CONFIG_PATH to point to a JSON file, or place the file at ~/.config/gmail-summarize/config.json. The file must contain only the fields below (no other sensitive data should be stored in this file):

{
  "email": {
    "imapHost": "imap.gmail.com",
    "imapPort": 993,
    "imapUsername": "[email protected]",
    "imapPassword": "your-app-password",
    "maxBodyChars": 2000
  }
}

Security notes

• Preferred: supply credentials via environment variables (IMAP_HOST, IMAP_PORT, IMAP_USERNAME, IMAP_PASSWORD) so no file on disk is read at all.
• When a config file is used, it should contain only the email fields listed above. The script reads only those four fields and nothing else from the file.
• The only external connection made is to the IMAP server declared in IMAP_HOST / email.imapHost. No other endpoints are contacted.
• Credentials are used solely to authenticate the IMAP session and are not logged or stored elsewhere by this skill.

When to use

• User asks "check my Gmail", "summarize my emails", "邮件摘要"
• Cron trigger message contains "gmail_digest"

Workflow

1. Run the fetch script via exec tool: python {workspace}/skills/gmail-summarize/scripts/fetch_unseen.py (replace {workspace} with your actual workspace root)

2. Parse the JSON array. Each item has: sender, subject, date, body

3. For each email compose one line: [date] sender | subject — one-sentence body summary

4. Send the full digest via MessageTool in this format:

   📬 邮件摘要 (N封，覆盖 MM/DD–MM/DD)

   • [日期] 发件人 | 主题 — 一句话摘要 • [日期] 发件人 | 主题 — 一句话摘要 ...

5. If result is empty, send: 📭 近两日暂无未读邮件

Output Rules

• Send the digest message ONLY. Do NOT add any extra comments, greetings, explanations, or follow-up questions before or after the digest.
• Do NOT say things like "主人，以下是您的邮件摘要" or "如需了解详情请告知" etc.
• The digest message itself is the complete and final response.
• The one-sentence body summary MUST be translated into Chinese. Sender names and subjects should keep their original text as-is.
