I've done some similar stuff. I wanted to reference some TLA+ community stuff. I was initially just copy-pasting the specs into mine, and that worked well enough, but it was a little tedious and I was kind of afraid I might accidentally forget to give attribution to someone if I used their spec. So I got Claude to build a TLA+ package manager for me. It's just a basic thing in Rust that allows me to plop a deps.json file into my TLA+ folder, and put a git repo url and commit hash, and then I use tree-sitter-tlaplus [1] to rename the modules to have a basic namespace to avoid collisions. It took about 30 minutes of fighting with Claude, but then it worked fine. As AI gets better and better and cheaper and cheaper, I suspect it will be easy to have tons of custom apps for everything. It's a brave new world. [1] https://github.com/tlaplus-c

Not an emacs person myself (yet!) - Carl Thuringer created tla-mode that apparently uses the grammar: https://github.com/carlthuringer/tla-mode Haven't tested it out myself. Happy to take any PRs if emacs needs its own set of query files; they would live in https://github.com/tlaplus-community/tree-sitter-tlaplus/tre... and they can be added to CI runs to ensure they stay in sync with changes to the parser.
