Gmail Checker 📧#

Fetch unread Gmail messages, filter out noise, deliver a prioritized digest.

Why#

Your inbox is full of automated emails, promotions, and updates. This skill surfaces what actually matters — security alerts, personal messages, and anything you've flagged as important.

When to Use#

• "Check my emails"
• "Any new mail?"
• "Give me an email digest"
• "What's in my inbox?"
• "Email summary"

Setup#

First-time users need Google OAuth credentials. If the script exits with a "missing file" error, read references/setup.md and walk the user through the setup flow.

bash

pip install google-api-python-client google-auth-oauthlib

How to Run#

bash

python3 scripts/check_gmail.py [hours]          # default: last 24h
python3 scripts/check_gmail.py --json [hours]   # structured JSON output

Config: Copy config.example.json to <DATA_DIR>/gmail-config.json and customize. The script prints the resolved <DATA_DIR> path if credentials are missing.

Data Directory#

Credentials and config resolve to:

text

1. $SKILL_DATA_DIR (set by agent platform)
2. ~/.config/gmail-checker/  (default fallback)

Any platform can set $SKILL_DATA_DIR to their preferred credential store. If unset, ~/.config/gmail-checker/ is used automatically. Works with OpenClaw, Claude Code, Codex, and any agent that can run Python scripts.

Priority Rules#

text

🔴 HIGH   → Sender domain or subject matches your config
🟡 MEDIUM → Gmail-labeled personal messages
🟢 LOW    → Everything else (still inbox, still unread)

text

Filtered out entirely:
• CATEGORY_PROMOTIONS
• CATEGORY_UPDATES
• CATEGORY_FORUMS
• CATEGORY_SOCIAL

Customize priorities in gmail-config.json:

text

high_priority_domains:   ["stripe.com", "github.com"]
high_priority_keywords:  ["security", "urgent", "billing"]

Output Example#

text

Unread Inbox (last 24h)

🔴 HIGH
  Security alert: new sign-in from unknown device
  from: Google <no-reply@google.com>

🟡 MED
  Re: dinner friday?
  from: Sarah <sarah@gmail.com>

🟢 LOW
