I’m currently developing a 2d-drafting package in Fortran & Tcl. The design is the result of 40 years in CAD. I don’t think I’m halfway through yet but when I am I’ll publish it to _gh_ and notify you all here; some components have already been published.  
In the meantime I thought you might be interested to see the plan for the current task that Claude is now implementing (a small scripting language). Other AI’s may give more or less detail, I just thought some people might be interested in this information.  
The file is wide so I’ve moved it to an attachment rather than inline.

Is there anything special about this plan or something of interest? I looked at it, but it seems just like a regular plan from an AI agent.

No, nothing special at all - just thought some people might be interested in seeing a bit of how the process works.
