QwenLM/Qwen3-Coder — reverse-engineered prompt

Build me an open source Python repo for Qwen3 Coder, a coding focused language model release that developers can quickly try, evaluate, and adapt.

I want the project to feel polished for people landing from GitHub. Include a clear README that explains what Qwen3 Coder is, where to find the model checkpoints on Hugging Face and ModelScope, what it is good at, and how to start chatting with it for coding tasks. Show that it supports very long context, many programming languages, coding agent workflows, browser use style tasks, and function calling.

Please include simple demos and examples that show practical use cases like generating a website, cleaning up a desktop folder, making a small game, creating ASCII art from sound, and using it as a vibe coding assistant. Also add space for fine tuning and evaluation scripts so more advanced users can test or adapt the model later.

Look up current docs online if you need to.
