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.\n\nIn 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.\n\nThe file is wide so I’ve moved it to an attachment rather than inline.\n\n[plan.txt](/uploads/short-url/mvRYAi50CPaIjGs5DvgPNxmh8TR.txt) (23.9 KB)", "url": "https://wpnews.pro/news/example-of-using-claude-fable", "canonical_source": "https://fortran-lang.discourse.group/t/example-of-using-claude-fable/11018#post_1", "published_at": "2026-07-25 08:27:51+00:00", "updated_at": "2026-07-25 08:36:38.841001+00:00", "lang": "en", "topics": ["ai-tools", "developer-tools"], "entities": ["simong", "Fortran", "Tcl", "Claude", "Fortran Discourse"], "alternates": {"html": "https://wpnews.pro/news/example-of-using-claude-fable", "markdown": "https://wpnews.pro/news/example-of-using-claude-fable.md", "text": "https://wpnews.pro/news/example-of-using-claude-fable.txt", "jsonld": "https://wpnews.pro/news/example-of-using-claude-fable.jsonld"}}
