{% raw %} Configure CI workflows to intelligently manage system resources through conditional execution rather than duplicating steps. Use matrix variables or job conditions to determine when resource-intensive operations should run. For resource monitoring tasks (like disk usage checks), define a condition that prevents redundant execution: ```yaml - name: print disk usage # Only run this step if the free_disk operation isn't executed if: ${{ !matrix.free_disk }} run: | echo "disk usage:" df -h ``` When configuring runners, explicitly document resource constraints and set appropriate flags that control resource management steps: ```yaml runners: - &job-windows os: windows-2025 free_disk: true # Explicitly mark jobs that need disk space freed <<: *base-job ``` This approach keeps workflows maintainable by avoiding duplicative steps, makes resource constraints visible, and ensures consistent behavior across different execution environments. {% endraw %}
