Setup Guide

Step 1: Create Google Cloud OAuth Credentials

1. Go to Google Cloud Console
2. Create a new project (or select existing)
3. Enable the Gmail API: APIs & Services > Library > search "Gmail API" > Enable
4. Create OAuth credentials: APIs & Services > Credentials > Create Credentials > OAuth client ID
5. Application type: Desktop app
6. Download the credentials.json file

Step 2: Configure the Skill

# Place credentials file
mkdir -p ~/.gmail-skill
cp credentials.json ~/.gmail-skill/credentials.json

# Run first-time setup
bash scripts/gmail-auth.sh setup

Step 3: Authorize

bash scripts/gmail-auth.sh login

This opens a browser window for Google OAuth consent. After authorization, tokens are stored locally at ~/.gmail-skill/token.json.

Configuration

Required binaries: python3, curl

Gmail Query Syntax

Use these operators with search and ai-summary:

• is:unread — Unread messages
• is:starred — Starred messages
• from:user@example.com — From specific sender
• to:user@example.com — To specific recipient
• subject:keyword — Subject contains keyword
• after:2026/01/01 — After date
• before:2026/12/31 — Before date
• has:attachment — Has attachments
• label:work — Has specific label
• in:inbox — In inbox

Security

Important: Data Consent for AI Features

AI commands (ai-summary, ai-reply, ai-prioritize) transmit email content (subject, sender, body) to api.evolink.ai for processing by Claude. By setting EVOLINK_API_KEY and using these commands, you explicitly consent to this transmission. Data is not stored after the response is returned. If you handle sensitive or confidential emails, review EvoLink's privacy policy before using AI features. Core Gmail operations (read, send, search, label) never transmit email content to any third party.

Credentials & Storage

Google OAuth credentials (credentials.json) and tokens (token.json) are stored locally at ~/.gmail-skill/. Tokens are never transmitted to any third party. The skill accesses Gmail only through Google's official OAuth 2.0 flow and Gmail API endpoints (gmail.googleapis.com).

AI Features (Optional)

When AI features are used (summarize, draft, prioritize), email content is sent to api.evolink.ai for processing by Claude. Data is discarded after the response is returned. No email data is stored by EvoLink. Review EvoLink's privacy policy before using AI features with sensitive emails.

EVOLINK_API_KEY is only required for AI features. Core Gmail operations (read, send, search, label) work without it.

File Access Controls

This skill only reads/writes within ~/.gmail-skill/ for credential and token storage. No other filesystem access is performed.

Required binaries: python3, curl

Network Access

• gmail.googleapis.com — Gmail API (core operations)
• oauth2.googleapis.com — OAuth token management
• accounts.google.com — OAuth consent flow
• api.evolink.ai — AI features only (optional)

Persistence & Privilege

This skill does not modify other skills or system settings. No elevated or persistent privileges are requested. OAuth tokens can be revoked at any time via bash scripts/gmail-auth.sh revoke or from Google Account Settings.
