What it can do

- Lets the assistant create sketches, extrude parts and export STL, discovering API endpoints as it goes.
- Reads and writes local files such as screenshots, exports and FeatureScript when run locally.
Limitations
- Early development; the author warns things may not work as expected.
- Streamable HTTP mode is experimental and disables local file access; no public hosted endpoint is offered.
