Milestones
Since SG-Lib 5.6 the toolbox can be driven by a generative AI — preferably Claude — through the batch-pool interface (executepool4claude). Each milestone below is a real, reproducible design: a plain-language task, the design conversation in which the part was constructed step by step, and a checked, printable result.
These are the actual English conversations of the toolbox, kept as teaching milestones. Renderings and STL downloads will be added here shortly.
