Been working for several days trying to figure out a solution. I'm building a plugin to bring in OpenRouter into Xcode so you can choose pretty much whatever cloud LLM you want easily. One thing I'm having trouble with is artifacts in the right hand pane. Specifically in /plan mode. Currently, it will write the plan in the transcript, it will even create a markdown card, but it will not put it in the artifact pane for preview and inline comment annotation for the next prompt. I can't seem to find the answer. Any help would be appreciated.
