[ahmet-cetinkaya]

Summary

• Add comprehensive Qwen Code integration as fourth AI assistant option
• Extend CLI, documentation, and build pipeline to support Qwen
• Maintain backward compatibility with existing assistants (Claude, Gemini, Copilot)

Changes Made

• CLI Integration: Added Qwen as option in src/specify_cli/__init__.py with proper help text and tool checking
• Shell Scripts: Extended scripts/update-agent-context.sh to support QWEN.md generation
• GitHub Actions: Added Qwen package creation in release workflow with .qwen/commands/*.md structure
• Documentation: Updated README.md, CONTRIBUTING.md, and templates to include Qwen CLI references
• Templates: Extended plan template to reference Qwen in agent file updates

Testing

• ✅ CLI help shows Qwen option: --ai claude, gemini, copilot, or qwen
• ✅ All commands function correctly with Qwen integration
• ✅ Check command runs without errors
• ✅ Follows established patterns from other AI assistants

Implementation Details

• Command Structure: Uses .qwen/commands/*.md format
• Context File: Generates QWEN.md in project root
• CLI Tool: Expects qwen command availability
• Installation URL: References https://github.com/QwenLM/qwen-code

This extends Spec Kit's AI assistant ecosystem to include Qwen while maintaining full compatibility with existing workflows.

Can't wait to get qwen code support as well

@ahmet-cetinkaya is this complete?
because i tried uvx --from git+https://github.com/ahmet-cetinkaya/spec-kit#feature/add-qwen-support specify
but i didn't see qwen code cli there
guide me if i did it wrong

[ahmet-cetinkaya]

@vjaykrsna There’s a small mistake in your command — when specifying a branch, you should use @ instead of #. Try this:

uvx --from git+https://github.com/ahmet-cetinkaya/spec-kit@feature/add-qwen-support specify

This will let you see the new option.

However, since spec-kit fetches its templates from releases, the tool won’t fully work this way.
To properly run the feature before release, you’ll need to clone the branch locally:

git clone https://github.com/ahmet-cetinkaya/spec-kit -b feature/add-qwen-support
cd spec-kit

uv sync
uv run specify

by default it fetch from github had to modify the function to get it to work after generating the files manually
hope they officially merge this soon

@ahmet-cetinkaya once you address the nit changes I highlighted, I am happy to merge this.

Hi @localden,

The requested changes are applied, and the branch is now ready to merge. Appreciate the review! 🚀

I usually keep lists numbered sequentially so they’re easier to read in raw Markdown, but if the 1. style is preferred, I’m happy to stick with that.
