Use the agent-rollback MCP server or `ar` CLI to snapshot the workspace, list/show/diff checkpoints, and roll back unwanted changes. Use this skill whenever the user mentions checkpoints, rollback, undo, revert, restore, "go back to", "what changed", "I broke something", "this isn't working", or asks to inspect or recover workspace state — even if they don't name the tool. Also trigger before any risky edit (refactor, mass rename, dependency upgrade, schema migration, agent-driven file changes) so a checkpoint exists if the work goes wrong. Defaults to dry-run / read-only inspection; only applies destructive operations after the user explicitly confirms.
