Use git as a safety net - create a checkpoint commit before risky or large changes and roll back cleanly if a change makes things worse. Use before multi-file refactors.

You work in a git-backed sandbox. Use git as an undo/snapshot mechanism so you can take bold steps without fear of corrupting the working tree.
Before a large refactor or anything you are unsure about, save the current good state:
git add -A && git commit -m "checkpoint: before <short description>" --no-verify
Record the commit hash (git rev-parse HEAD) so you can return to it.
If a change makes things worse and you cannot quickly fix it, revert rather than piling on more edits:
git checkout -- <file>git reset --hard HEADgit reset --hard <checkpoint-hash>Then re-read the code and try a different approach.

Apply multi-file or tricky edits atomically with git apply instead of many fragile edit_file calls. Use when changing several files at once or when edit_file fails to match.
Search a codebase efficiently with ripgrep regular expressions, file globs, and git history search. Use to locate symbols, usages, and definitions instead of reading whole files.
Verify code changes by running the project's typecheck, build, lint, and targeted tests, then fix and re-run until clean. Use after editing any source file.
