Safety nets builders made after an agent deleted files, broke a deploy or looped on a failing test. 5 matching use cases below, each with a public source.
Steward saves checkpoints of long Claude Code runs so you can resume after your usage window resets. A portable preview also supports Codex and local models, and switching provider starts a fresh chat from the checkpoint.

Shipback deploys a folder to any SFTP host (cPanel, Plesk, DirectAdmin or a VPS) and backs up every file it overwrites first. One command restores the previous files, it refuses to undo over a live edit, and its MCP server has no switch to skip the backup, so Claude Code, Cursor or any MCP client can deploy safely.

SpendVeto adds a budget, a loop detector and a kill switch to Claude Code and Codex. When an agent kept rerunning a failing test, each retry being a paid model call, it stopped the loop at call 7.

Claude Code's rewind does not track shell commands, so if an agent deletes your src folder and .env file, nothing comes back. Oops records what the agent does so you can undo it, including deleted files.
