# CAD Viewer Development

Use this reference only when the user asks to modify, debug, or iterate on CAD
Viewer source.

CAD Viewer source development happens in the root
source workspace, not inside this generated skill runtime.

If you are not currently working directly in the editable source workspace, ask
the user for the correct checkout and run the agent from that repository.

Once inside the repository, read root `AGENTS.md` for guidance on modifying and running the Viewer.
