Gmail

Interact with Gmail for email management, search, and organization.

Installation

Install Python dependencies:

bash

pip install --user google-auth google-auth-oauthlib google-api-python-client keyring pyyaml

Download the skill from Releases or use directly from this repository.

Setup Verification

After installation, verify the skill is properly configured:

bash

python scripts/gmail.py check

This will check:

Python dependencies (google-auth, google-auth-oauthlib, google-api-python-client, keyring, pyyaml)
Authentication configuration
Connectivity to Gmail API

If anything is missing, the check command will provide setup instructions.

Authentication

Gmail uses OAuth 2.0 for authentication. For complete setup instructions, see:

GCP Project Setup Guide - Create project, enable Gmail API
Google OAuth Setup Guide - Configure credentials

Quick Start

Create

~/.config/agent-skills/google.yaml

yaml

oauth_client:
  client_id: your-client-id.apps.googleusercontent.com
  client_secret: your-client-secret

Run
```
python scripts/gmail.py check
```
to trigger OAuth flow and verify setup.

OAuth Scopes

The skill requests granular scopes for different operations:

Scope	Permission	Used For
`gmail.readonly`	Read messages, labels, settings	Listing and reading messages
`gmail.send`	Send emails	Sending messages and drafts
`gmail.modify`	Modify labels and metadata	Managing labels on messages
`gmail.labels`	Manage labels	Creating and listing labels

Scope Errors

If you encounter "insufficient scope" errors, revoke your token and re-authenticate:

Revoke at https://myaccount.google.com/permissions

Clear token:

keyring del agent-skills gmail-token-json

Re-run:
```
python scripts/gmail.py check
```

Commands

bash

python scripts/gmail.py check

This validates:

Python dependencies are installed

Troubleshooting

Check command fails

Run

python scripts/gmail.py check

to diagnose issues. It will provide specific error messages and setup instructions.

Authentication failed

Verify your OAuth client ID and client secret are correct in
```
~/.config/agent-skills/google.yaml
```

Token expired or corrupted - clear and re-authenticate:

bash

keyring del agent-skills gmail-token-json
python scripts/gmail.py check

Permission denied

Your OAuth token may not have the necessary scopes. Revoke access at https://myaccount.google.com/permissions, clear your token, and re-authenticate.

Import errors

Ensure dependencies are installed:

bash

pip install --user google-auth google-auth-oauthlib google-api-python-client keyring pyyaml

Rate limiting

Gmail API has quota limits. If you hit rate limits, wait a few minutes before retrying. For high-volume usage, consider requesting quota increases in the Google Cloud Console.

API Scopes

This skill requests the following OAuth scopes:

https://www.googleapis.com/auth/gmail.readonly

- Read email messages and settings

https://www.googleapis.com/auth/gmail.send

- Send email messages

https://www.googleapis.com/auth/gmail.modify

- Modify labels and message metadata

https://www.googleapis.com/auth/gmail.labels

- Manage labels

These scopes provide full email management capabilities while following the principle of least privilege.

Security Notes

OAuth tokens are stored securely in your system keyring
Client secrets are stored in
```
~/.config/agent-skills/gmail.yaml
```
with file permissions 600
No passwords are stored - only OAuth tokens
Tokens refresh automatically when using the skill
Browser-based consent ensures you approve all requested permissions

Always review OAuth consent screens before granting access to your Gmail account.
