| 1. Look at the build errors from the modularpipeline check | |
| 2. Identify the root cause of the failure | |
| 3. Implement and commit a fix directly to the PR branch: ${pr.branch} | |
| 4. Ensure the fix follows the TUnit coding standards | |
| Focus on fixing only the build errors - do not make unrelated changes.`; | |
