Check my Jira board and create a Monday morning briefing document.

For each issue assigned to me or updated since last Friday:
1. List the issue key, summary, status, and priority
2. Flag any issues that are BLOCKED (include what's blocking them)
3. Flag any issues with HIGH or CRITICAL priority
4. Note issues that changed status over the weekend

Group the output into:
- URGENT: Blocked or Critical priority issues needing action today
- IN PROGRESS: Issues I'm actively working on
- UPCOMING: Issues in To Do that I should plan for this week
- COMPLETED: Issues resolved since last Friday (for standup update)

Save the output as "monday-briefing-[today's date].md" in my workspace folder.

Keep the format clean and scannable. No fluff — just the facts I need for standup.
