README

pi-extension-reverse-last

Session-local undo for Pi write and edit file changes.

What it does

  • Captures pre-change file snapshots for successful write/edit tool calls.
  • Maintains a per-session undo stack.
  • Restores one or multiple recent changes with a command.

Install

pi install npm:@firstpick/pi-extension-reverse-last

Configuration

  • PI_REVERSE_LAST_STATE_DIR (optional)
    • Override undo state storage directory.
    • Accepts absolute paths or home-relative paths.
    • Default: ~/.pi/agent/state/reverse-last

Commands

  • /reverse-last [count] — undo last successful file changes in current session.

Tools

  • reverse_last — undo the most recent write/edit file changes captured in this session.

Example view

/reverse-last
Restored 1 file from the session undo stack:
- src/config.ts

/reverse-last 2
Restored 2 recent file changes.

This is a quick escape hatch for recent Pi write/edit changes in the current session.
