Could you build this?
Partial A macOS app with an embedded terminal is buildable with Swift and libghostty, but the signature feature of rewinding a specific Claude Code prompt depends on how Claude Code stores session state, which requires reverse-engineering and careful native work.
What it would actually take: Use Swift/AppKit with a libghostty-based terminal surface, plus a sidebar that tracks agent process state. The hard part is safely integrating with Claude Code's internal session and checkpoint files to roll back to a prior prompt, which requires deep knowledge of macOS process handling and the tool's internals.
