+description: Synchronize Google services (Email, Calendar) with PicoClaw
+---
+
+# Google Sync Skill
+
+This skill allows the agent to synchronize and manage user's Google services.
+
+## Available Tools
+
+### `google`
+Provides access to Gmail and Google Calendar.
+- `action="list_emails"`: Fetches recent emails.
+- `action="list_events"`: Fetches upcoming calendar events.
+
+## Periodic Synchronization
+
+To keep the agent's knowledge up-to-date, use the `cron` tool to schedule periodic sync tasks.
+
+### Example: Sync Every 4 Hours
+Call `cron` tool:
+```json
+{
+  "action": "add",
+  "message": "Update my knowledge of recent emails and calendar events using the google tool.",
+  "every_seconds": 14400,
+  "deliver": false
+}
+```
+
+## Self-Syncing Implementation
+
+When triggered by cron, the agent should:
+1. Call `google(action="list_emails")`
+2. Call `google(action="list_events")`
+3. Summarize the findings.
+4. Update its long-term knowledge or session summary.
