Ai Second Brain - Gmail Digest

Managing a high-volume Gmail inbox manually leads to missed deadlines and decision fatigue. This skill triages your messages, drafting context-aware replies in your specific writing style and extracting deadlines directly into your Google Calendar.

What it does

• Automated Triage identifies urgent threads, summarizes conversations, and categorizes low-priority mail into a compact digest.
• Style Learning analyzes your sent folder to build a voice profile, ensuring drafts use your specific greetings, tone, and sign-offs.
• Safe Drafting creates Gmail drafts for your review rather than sending emails directly, preventing accidental or incorrect replies.
• Calendar Integration detects deadlines or meeting requests and creates calendar events with deep links back to the original email thread.
• Local Logging maintains a daily markdown record of all processed emails, summaries, and actions taken in a local directory.

How it works

1. Run voice to let the agent analyze your sent messages and establish your unique email writing style.
2. Execute preview to see a read-only summary of your recent inbox, including proposed drafts and calendar events without making changes.
3. Run the standard digest command to process the last 24 hours of mail, creating drafts and marking threads as processed in Gmail.
4. Use setup to verify your Gmail and Google Calendar connector permissions and initialize the local data folder.

Frameworks & tools

Built for Claude Code using the claude.ai Gmail and Google Calendar MCP connectors. It uses local file system storage for voice profiles and digest logs.

Why this beats prompting it yourself

Standard prompting often struggles with maintaining a consistent personal voice and correctly identifying relative dates like "next Friday." This skill implements a dedicated voice-learning loop and a systematic duplicate-check for calendar events to ensure high-fidelity automation.

Use cases

• Catch up on a weekend's worth of email in minutes with a prioritized summary.
• Automatically draft standard responses to routine inquiries using your personal tone.
• Ensure project deadlines mentioned in threads are never missed by syncing them to your schedule.
• Filter out bulk notifications and newsletters into a single readable table.

Known limitations

Requires the claude.ai Gmail connector. It cannot send emails, delete threads, or manage attachments. Calendar events are created without attendees to prevent accidental invites.
