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:

First, show them the complete email details:

From (which account)

To

CC/BCC (if any)

Subject

Full body text

Ask: "Do you want me to send this email?"

ONLY run the send command AFTER the user explicitly confirms (e.g., "yes", "send it", "go ahead")

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:

Go to Google Cloud Console

Create a project (or select existing)

Enable Gmail API and People API (APIs & Services → Library)

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

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.
