Because none of that requires "AI". You can use a script to clone GitHub top NPM repos (by whatever measure), and then 'simply' try to migrate them to Deno and log all the errors and warnings. Maybe you compile those errors in a neat list with an LLM, and ask it to emphasize things it considers important. But even that can be done inside the script with loglevels and maybe some regex.

Parent is getting downvoted because they're suggesting something that is akin to "why are you running this simple, reliable, efficient Python script instead of feeding inputs to an LLM and praying you get the outputs you want".

Respect yourself by respecting your craft.
