How It Works

1. Thread Retrieval: Fetches the entire email thread using the Gmail API
2. Text Processing: Extracts and combines all message bodies
3. Sentence Scoring: Scores sentences based on:
   • Email-specific keywords (action, deadline, decided, etc.)
   • Position in message (first/last sentences weighted higher)
   • Presence of dates, times, numbers
4. Summary Generation: Selects top-scoring sentences and formats them
5. Action Item Detection: Uses pattern matching to find tasks and deadlines
6. Storage: Saves summaries to SQLite for future reference

Action Item Patterns

The skill detects action items using patterns like:

• "Need to...", "Should...", "Must..."
• "Please...", "Action item:..."
• "Follow up on..."
• "Deadline is...", "By [date]..."

Action items include:

• Priority level (high/medium/low)
• Assignee (when detectable)
• Deadline (when specified)

Data Storage

Summaries are stored in SQLite at ~/.openclaw/skills/email-summarizer/summaries.db:

• thread_summaries: Thread summaries with metadata
  • Thread ID, subject, participants
  • Summary text, key points, action items
  • Length, format, creation date

Dependencies

• @openclaw/email: For Gmail API access
• sqlite3: For local data storage

Requirements

• Gmail account connected via email skill
• OAuth credentials with Gmail scope

Error Handling

The skill handles common errors:

• Thread not found
• Empty threads
• Email skill connection issues
• Invalid thread IDs
