> I found 67 call sites. This is a pretty substantial change. Maybe we should just commit the signature change with a TODO to update all the call sites, what do you think?

I think some of this is a problem in the agent's design. I've got a custom harness around GPT5.4 and I don't let my agent do any tool calling on the user's conversation. The root conversation acts as a gatekeeper and fairly reliably pushes crap responses like this back down into the stack with "Ok great! Start working on items 1-20", etc.

Ehhhhh, "problem" is a strong word. Sometimes you're throwing out a lot of signal if you don't let the coding agent tell you it thinks your task is a bad idea. I got a PR once attempting to copy half of our production interface because the author successfully convinced Claude his ill-formed requirements had to be achieved no matter what.
