Your AI agent just edited 14 files. Where is your undo button?
An AI coding agent without version control is a power tool with no off switch. Its built-in undo expires and misses things — Anthropic itself says checkpoints are ‘not a replacement for git.’ Here is why git and GitHub are the safety net every LLM coding agent assumes you have: diffs to see what it did, branches to contain it, pull requests to review it, and @claude to put the agent right inside GitHub.
