# VlinderCLI **Debug and repair AI agents.** When AI agents fail, rewind to the failure, inspect the exact state, test a fix, and replay. --- ## How It Works ```text $ vlinder agent run todoapp # agent fails $ vlinder session fork wired-pig-543e \ --from a1b2c3d4 --name fix # rewind to before the failure $ vlinder agent run todoapp --branch fix # replay with fix $ vlinder session promote fix # promote the fixed timeline ``` Every decision your agent makes is captured as a content-addressed Merkle DAG — same data model as git. Nothing is lost. Both timelines are preserved. --- ## Links - [vlindercli.dev](https://vlindercli.dev/) — home - [docs.vlindercli.dev](https://docs.vlindercli.dev/) — documentation - [blog.vlindercli.dev](https://blog.vlindercli.dev/) — blog - [github.com/vlindercli/vlindercli](https://github.com/vlindercli/vlindercli) — source code - [discord.vlindercli.dev](https://discord.vlindercli.dev/) — community
