Tips & Best Practices

1. Use Copilot Workspace for greenfield features — create the issue, let Workspace plan and scaffold, then refine locally
2. Enable Copilot Reviews on all PRs to catch common bugs and style issues before human reviewers
3. In Agent Mode, always review the proposed plan before confirming execution — it is not reversible mid-task
4. Use Copilot for CLI to translate complex awk/sed/jq commands from natural language rather than memorizing syntax
