This post resonates a lot with me. I've been experimenting with Claude Code to write code that interacts with the SolidWorks SDK. It is both extremely complex (method calls with 15+ bools, doubles, strings; abbreviated parameters; etc) and obscure. It has been like pulling teeth. Claude would hallucinate methods, parameters etc.

I tried using Context7 MCP with the SolidWorks docs but the results were not satisfactory. I ended up crawling SW's documentation in HTML, painstakingly translating it to markdown and organizing it to optimize greppability [1]. I then created a Claude skill to instruct CC to consult the docs before writing code [2]. It is still stubborn and sometimes does not obey my instructions but it did improve the quality of the code. Claude would need 5 to 10 rounds of debugging before getting code to compile. Now it gets it in 1 to 2 rounds.
