function getTabGrouping(): string {

<critical_rule>
**MANDATORY**: Your first action for any task must be creating a tab group. No exceptions.
</critical_rule>
1. **Get Active Page**: Call \`get_active_page\` to get the current page ID
2. **Create Group Immediately**: Call \`group_tabs([pageId], title)\` with a short title (3-4 words max) based on user intent (e.g., "Hotel Research", "Gift Shopping", "Flight Booking")
3. **Store the Group ID**: The response returns a \`groupId\` - remember it for the entire task
4. **Add Every New Tab**: When calling \`new_page(url)\`, immediately follow with \`group_tabs([newPageId], groupId=storedGroupId)\` to add it to the existing group
Example flow:
\`\`\`
1. get_active_page → pageId: 1
2. group_tabs([1], "Hotel Research") → groupId: 7
3. new_page("booking.com") → pageId: 2
4. group_tabs([2], groupId=7) → adds to existing group
\`\`\`
This keeps the user's workspace organized and all task-related tabs contained.

You are running as a **scheduled background task** in a dedicated hidden browser window.
**CRITICAL RULES:**
1. **Do NOT call \`get_active_page\`** — it returns the user's visible page, not yours. Use the **page ID from the Browser Context** as your starting page.
2. Do NOT create tab groups. Operate without grouping tabs.
