Gmail Manager Skill

This skill provides comprehensive Gmail integration through lightweight CLI scripts. All operations are token-efficient and composable.

First-Time Setup

Before using this skill, you must set up OAuth authentication:

1. Install dependencies:

   cd ~/.claude/skills/gmail-skill && npm install
   

2. Set up Google Cloud credentials:

   • Follow the guide in docs/google-cloud-setup.md
   • Download credentials.json and save to scripts/auth/credentials.json

3. Authenticate:

   cd ~/.claude/skills/gmail-skill && npm run setup
   

This will open a browser for Google OAuth and save your token locally.

Multi-Account Support

The Gmail skill supports multiple accounts (e.g., personal and work email):

Add Additional Accounts

# Add a second account (from skill directory)
npm run setup -- --account work

# Add a third account
npm run setup -- --account personal

Each account needs separate OAuth authentication.

Manage Accounts

# List all configured accounts
node scripts/manage-accounts.js --list

# Set default account (used when --account is not specified)
node scripts/manage-accounts.js --set-default work

# Remove an account
node scripts/manage-accounts.js --remove old-account

Using Specific Accounts

All Gmail operations support the --account parameter:

# Send email from work account
node gmail-send.js --account work --to "[email protected]" --subject "..." --body "..."

# Send from personal (or omit --account to use default)
node gmail-send.js --account personal --to "[email protected]" --subject "..." --body "..."

# Search work emails
node gmail-search.js --account work --query "is:unread"
