pi-rewind-chat

Per-message rewind extension for the Pi coding agent.

Features

• /rewind — Pick any user message, rollback code, chat, or both to that point
• /rewind-undo — Reverse the last rewind (repeatable — walks back through multiple rewinds)
• Code checkpoints work like Claude Code's: snapshot the pre-edit content of files touched by tool calls each turn, no git required
• Chat rewind is non-destructive: it moves the conversation branch pointer (via Pi's native tree navigation), it doesn't delete history
• Preview affected files and scope (code/chat/both) before confirming

Note: Checkpoints are stored in-memory per session. They won't persist if you restart Pi. This prevents feedback loops that could cause infinite message cycles.
