Create Plan.md with Claude Code Opus, Execute Plan.md locally in Open Code using Qwen 3.6 27B Q8

Does anyone do this? Any tips? I've been experimenting with plan creation in Claude Code Opus and telling Claude it will be execute by a local model so be very specific. Then I write this to disk. Then I load up Claude again but setting the API url to local host and local model. Then execute using Qwen 3.6 27B Q8 in Claude Code in VS Code. But, I thought I could save setting the API base URL and reloading Claude again by just using Open Code purely local and execute the plan.md. So Claude is always Cloud, Open Code is always Local.
