Investigate the Sentry issue: $ARGUMENTS

1. Use the Sentry MCP tool `get_issue` to fetch the full issue with stack trace (issue ID or URL: $ARGUMENTS)
2. Use `get_issue_summary` to get Seer's root cause analysis
3. Use `get_events` to get the most recent 3 error events
4. Analyze the stack trace and identify the root cause
5. Look at the relevant source files using the Read tool
6. Propose a fix with a code diff
7. Estimate the blast radius (how many users are affected)
