// FIELD NOTES · PRO TIPS
- ◆Run it inside your actual git repo — Aider commits its own changes, so work in a branch you can easily diff and revert.
- ◆Add files to context explicitly (/add) rather than letting it guess; precise context gives much better edits.
- ◆Use /diff and /undo liberally — reviewing every change before moving on keeps quality high.
- ◆Pick a strong underlying model (Claude/GPT-4-class) in settings; Aider's quality depends heavily on the model behind it.
