Most of them are but when I need it to learn something from one already done I just point it to that workspace, like "For the invoices app take a look at inventory workspace and learn about X and Y" or "For Prince of Persia find all available code and references online and propose architecture changes to adapt to Swift on MacOS" so yes, it learns from both local or online sources
Yes that solve the knowledge part but there are also steps I need to repeat. Example: how to run a code based on risk level. That requires a tool, not just text.
