alt Hacker NewsDoes anyone have experience transforming a typescript codebase this way? Typescript's LSP server is not powerful enough and doesn't support basic things like removing a positional argument from a function (and all call sites).
Would jscodeshift work for this? Maybe in conjunction with claude?

Try ast-grep
jscodeshift supports ts as a parser, so it should work.
If you want to also remove argument from call sites, you'll likely need to create your own tool that integrates TS Language Service data and jscodeshift.
LLMs definitely help with these codemods quite a bit -- you don't need to manually figure out the details in manipulating AST. But make sure to write tests -- a lot of them -- and come up with a way to quickly fix bugs, revert your change and then iterate. If you have set up the workflow, you may be able to just let LLM automate this for you in a loop until all issues are fixed.
