Gmail Skill

Gmail Skill - Email & Contacts Access

Read, search, and send Gmail emails. Access Google contacts.

CRITICAL: Email Sending Confirmation Required

Before sending ANY email, you MUST get explicit user confirmation.

When the user asks to send an email:

1. First, show them the complete email details:
   • From (which account)
   • To
   • CC/BCC (if any)
   • Subject
   • Full body text
2. Ask: "Do you want me to send this email?"
3. ONLY run the send command AFTER the user explicitly confirms (e.g., "yes", "send it", "go ahead")
4. NEVER send an email without this confirmation, even if the user asked you to send it initially

This applies even when:

• The user says "send an email to X"
• You are in "dangerously skip permissions" mode
• The user seems to be in a hurry

Always confirm first. No exceptions.

First-Time Setup (One-Time, ~2 minutes)

On first run, the script will guide you through setup. You need to create a Google Cloud OAuth client once:

1. Go to Google Cloud Console
2. Create a project (or select existing)
3. Enable Gmail API and People API (APIs & Services → Library)
4. Configure OAuth consent screen:
   • User Type: External
   • App name: Gmail Skill
   • Add yourself as test user
   • Add scopes: gmail.readonly, gmail.send, gmail.modify, contacts.readonly
5. Create OAuth client ID:
   • Application type: Desktop app
   • Download JSON → save as ~/.claude/skills/gmail-skill/credentials.json

Then just run any command - browser opens, you approve, done. Works for all your accounts.

Note: If you previously used gmail-reader, you'll need to re-authenticate to grant the new gmail.send scope.

python3 ~/.claude/skills/gmail-skill/gmail_skill.py mark-read "id1,id2,id3" --account user@gmail.com

Mark Done (Archive)

python3 ~/.claude/skills/gmail-skill/gmail_skill.py star "id1,id2,id3" --account user@gmail.com

Message format (Superhuman-compatible)

send and draft build multipart/alternative messages (plain text + simple HTML paragraphs, no hard line wraps, proper-case headers). Drafts created this way appear and edit cleanly in Superhuman, including threaded replies and attachments (tested 2026-10-08 with three canary drafts).

Extra options for both send and draft:

• --body-file PATH: read the body from a file (avoids shell quoting for long emails)
• --attach PATH: attach a file (repeatable)
• --reply-to-id MESSAGE_ID: thread the message as a reply (sets In-Reply-To/References and threadId). Available on send as well as draft.

Recommended outreach flow: create drafts in the right account and thread, the user reviews and sends from Superhuman, and only use send after explicit per-email confirmation.

Create Draft

Creates a draft email. Use --reply-to-id when replying to an existing email to ensure proper threading in email clients like Superhuman.

python3 ~/.claude/skills/gmail-skill/gmail_skill.py draft --to EMAIL --subject "Subject" --body "Body text" [--reply-to-id EMAIL_ID] [--cc EMAIL] [--bcc EMAIL] [--account EMAIL]

Required arguments:

• --to / -t - Recipient email address
• --subject / -s - Email subject line
• --body / -b - Email body text

Optional arguments:

• --reply-to-id / -r - Message ID to reply to (adds proper In-Reply-To and References headers for threading)
• --cc - CC recipients (comma-separated)
• --bcc - BCC recipients (comma-separated)
• --account / -a - Create draft in specific account

Example (new email):

python3 ~/.claude/skills/gmail-skill/gmail_skill.py draft \
  --to "recipient@example.com" \
  --subject "Draft for Review" \
  --body "Here's my draft message."

Example (reply to existing email):

python3 ~/.claude/skills/gmail-skill/gmail_skill.py draft \
  --to "sender@example.com" \
  --subject "Re: Original Subject" \
  --body "Thanks for your email..." \
  --reply-to-id 19b99b3127793843 \
  --account work@company.com
