- ◆Use Copilot Chat to explain unfamiliar code or errors instead of tab-completions only; it's the more powerful half of the product.
- ◆Review every suggestion like a code review — Copilot confidently produces plausible-looking bugs, especially around edge cases.
- ◆Open related files in your editor; Copilot reads open tabs for context and suggestions improve noticeably.
