What this package can reach

Detected automatically from the source at version 0.1.5. This describes access, not safety — you decide whether it's appropriate for what the package claims to do.

  • 🤖
    Behavior — Changes how the agent thinks Modifies the system prompt, injects messages, or rewrites conversation context.
  • Commands — Runs shell commands Spawns processes on your machine.
  • 📁
    Files — Reads files outside your project Touches paths beyond the working directory, such as your home folder.
  • Keystrokes — Reads raw terminal input Hooks ui.onTerminalInput, so it sees what you type. Legitimate for shortcut handling; the same access a keylogger needs.
  • UI — Draws its own interface Renders widgets, footers, dialogs or full-screen views.
