pi-system-prompt-switcher

Switch Pi's active system prompt from files in ~/.pi/agent/systems/.

This package does one thing: /system-prompt picks a prompt file, persists that choice, then reloads Pi so the next turn uses it. There is no file watcher. Editing a prompt file takes effect after a reload or after selecting it again.

Install

pi install npm:pi-system-prompt-switcher

Prompt files

Put prompt files directly in:

~/.pi/agent/systems/

Example:

~/.pi/agent/systems/default.md
~/.pi/agent/systems/reviewer.md
~/.pi/agent/systems/prototype.md

Hidden files and subdirectories are ignored. Symlinks are ignored so selections cannot escape the systems directory.

Usage

Interactive picker:

/system-prompt

Direct switch:

/system-prompt reviewer.md

Selection is stored in:

~/.pi/agent/system-prompt-switcher.json

On interactive startup, Pi lists the active prompt filename in a [System Prompt] section.

After a successful switch, the extension calls Pi's reload flow. The selected prompt is appended to Pi's effective system prompt under an Active system prompt heading, preserving Pi's generated tool guidance, skills, project context, date, and cwd.
