Best Practices (2025)
Do:
- Use Workspace for Issues: Start a task from a GitHub Issue -> "Open in Workspace".
- Comment Driven Dev: Write a comment
// Calculate fibonacci, wait for completion. - Context: Keep relevant files open. Copilot looks at open tabs for context.
Don't:
- Don't blindly accept: Verify security and logic.
