README

henyo-pi-qwen3

A pi extension that prepends the Qwen system identity (You are Qwen, created by Alibaba Cloud. You are a helpful assistant.) to the system prompt whenever a Qwen3 model is selected.

Installation

pi install npm:henyo-pi-qwen3

How it works

  1. session_start — Notifies if the current model is Qwen3.
  2. model_select — Notifies when switching to a Qwen3 model.
  3. before_agent_start — If the active model ID matches /^qwen3/i, prepends the Qwen identity text to the system prompt before the agent loop begins.

Customization

To change the model regex or prepend text, fork this repo and edit the constants in index.ts:

Constant Default Description
MODEL_PREFIX_REGEX /^qwen3/i Regex to match model IDs that trigger the prompt prepend
PREPEND_TEXT You are Qwen... Text prepended to the system prompt
