Lesson

Review starts before the agent does anything. Commit the folder, so git has a clean point to compare against, then let the agent work, then look at exactly what changed with git status and git diff, or with /diff inside either agent, which also shows new files git is not tracking yet. OpenAI's Codex page gives the same advice in one line, to make git checkpoints before and after a task so you can revert. Read every changed line of anything that can spend money. For other files, the list of what changed is often enough to catch the edit that should not be there.

Before, after, and what rewind cannot reach: commit before the agent, run the session, read the diff, commit when it works; checkpoints undo file edits only, not files a script made, renders, or money spent.
