Investigate this GitHub Actions URL: $ARGUMENTS
Use the gh CLI to analyze this workflow run. Your investigation should:
1. **Get basic info & identify actual failure**:
- What workflow/job failed, when, and on which commit?
- CRITICAL: Read the full logs carefully to find what SPECIFICALLY caused the exit code 1
- Distinguish between warnings/non-fatal errors vs actual failures
- Look for patterns like "failing:", "fatal:", or script logic that determines when to exit 1
- If you see both "non-fatal" and "fatal" errors, focus on what actually caused the failure
2. **Check flakiness**: Check the past 10-20 runs of THE EXACT SAME failing job:
- IMPORTANT: If a workflow has multiple jobs, you must check history for the SPECIFIC JOB that failed, not just the workflow
- Use `gh run list --workflow=<workflow-name>` to get run IDs, then `gh run view <run-id> --json jobs` to check the specific job's status
- Is this a one-time failure or recurring pattern for THIS SPECIFIC JOB?
- What's the success rate for THIS JOB recently?
- When did THIS JOB last pass?
3. **Identify breaking commit** (if there's a pattern of failures for the specific job):
- Find the first run where THIS SPECIFIC JOB failed and the last run where it passed
- Identify the commit that introduced the failure
- Verify by checking: does THIS JOB fail in ALL runs after that commit? Does it pass in ALL runs before?
- If verified, report the breaking commit with high confidenc
