The tool acts as a continuous safety net, letting developers revert to a known good state at any time. Inspired by a senior developer's advice to commit at each passing state, the tool is modeled as a simple two-state machine. The Nushell prototype and Rust implementation are both discussed, highlighting how the logic simplifies to a single meaningful state transition. Users are advised to squash the resulting commits before pushing. ## Full article daily.dev links to this article rather than hosting it.
