Gmail

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

Installation

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

Setup Verification

After installation, verify the skill is properly configured:

$SKILL_DIR/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:

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

Quick Start

1. Create ~/.config/agent-skills/google.yaml:

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

2. Run $SKILL_DIR/scripts/gmail.py check to trigger OAuth flow and verify setup.

On scope or authentication errors, see the OAuth troubleshooting guide.

Commands

See permissions.md for read/write classification of each command.

check

Verify configuration and connectivity.

$SKILL_DIR/scripts/gmail.py check

This validates:

• Python dependencies are installed
• Authentication is configured
• Can connect to Gmail API
• Displays your email address and mailbox statistics

auth setup

Store OAuth 2.0 client credentials for custom OAuth flow.

$SKILL_DIR/scripts/gmail.py auth setup \
  --client-id YOUR_CLIENT_ID \
  --client-secret YOUR_CLIENT_SECRET

Credentials are saved to ~/.config/agent-skills/gmail.yaml.

auth reset

Clear stored OAuth token. The next command that needs authentication will trigger re-authentication automatically.

$SKILL_DIR/scripts/gmail.py auth reset

Use this when you encounter scope or authentication errors.

auth status

Show current OAuth token information without making API calls.

$SKILL_DIR/scripts/gmail.py auth status

Displays: whether a token is stored, granted scopes, refresh token presence, token expiry, and client ID.

Gmail Search Query Syntax

Common search operators:

Operator	Description	Example
from:	Sender email	from:[e-mail]
to:	Recipient email	to:[e-mail]
subject:	Subject contains	subject:meeting
label:	Has label	label:important
has:attachment	Has attachment	has:attachment
is:unread	Unread messages	is:unread
is:starred	Starred messages	is:starred
after:	After date	after:2024/01/01
before:	Before date	before:2024/12/31
newer_than:	Newer than period	newer_than:7d
older_than:	Older than period	older_than:30d

Combine operators with spaces (implicit AND) or OR:

# AND (implicit)
from:[e-mail] subject:meeting

# OR
from:[e-mail] OR from:[e-mail]

# Grouping with parentheses
(from:[e-mail] OR from:[e-mail]) subject:meeting

Error Handling

Authentication and scope errors are not retryable. If a command fails with an authentication error, insufficient scope error, or permission denied error (exit code 1), stop and inform the user. Do not retry or attempt to fix the issue autonomously — these errors require user interaction (browser-based OAuth consent). Point the user to the OAuth troubleshooting guide.

Retryable errors: Rate limiting (HTTP 429) and temporary server errors (HTTP 5xx) may succeed on retry after a brief wait. All other errors should be reported to the user.

Model Guidance

This skill makes API calls requiring structured input/output. A standard-capability model is recommended.
