If doing it directly fails (not surprising) wouldn't the next thing (maybe the first thing) to do was to have AI write a codemod to do what needed to be done then apply the codemod? Then all you need to do is get the codemod right and apply it to as many files as you need. Seems much more predictable and context-efficient.

This should work really well, but you still need to first ensure the agent is able to test the code (both through automated tests and "manually" poking at it) so it can verify the changes made actually work.
