And then it always has the fucking gall to say “sorry, here’s the *actual* solution” as though that won’t also be incorrect somehow

GPT-5.2 has been hallucinating like a mf. Giving me libraries that don’t exist, CLI flags that don’t exist, and Homebrew packages that don’t exist 😭

I’ve been trying different models that it offers. The most recent one I used that made me so fucking angry is Claude Sonnet 4.5. Just now I asked it “where is the JSON output being created in this codebase” and it told me a file that DOESN’T FUCKING EXIST even though I gave it all the necessary context

Honestly if it’s a big enough codebase, I don’t blame it for not being able to figure that out. You’re much better off using an IDE and going through the references of the method you’re calling to figure out which line is writing the JSON

I didn’t know what method it was or what it would have been called and searching for relevant search terms returned like 200 results. I am aware of all the tools available to find what I was looking for. Anyway I found it by setting Copilot to Agent mode instead of Ask mode so that when I provided the file structure as context, it could independently look through the actual contents of the files (without me having to provide ALL the files’ contents as context and overload its context window).

Ahhh yeah that makes sense. I didn’t realize you were passing all of them through as context 😭

I guess the real problem I was running into was that I never use Agent mode because I don’t ever want it making any edits to my files ever, but I guess it was actually necessary in this case for it to be able to find the context it needed to answer the question. But yeah the C codebase was too complicated and unfamiliar for “just search for method uses” to be helpful. Like yeah obviously I had tried that, I’m not an idiot, and I still used that after the AI gave me a place to first start lookin

Ohhhh C? That makes way more sense now. There’s probably way too many libraries to look for 😭

I wasn’t passing them all through as context, just the folder structure. But I guess that doesn’t actually let the AI look through the actual file contents, so I needed to use agent mode to have it actually independently decide which files’ context it needs. And yeah I have no prior C experience (some C++ tho) and this is a mature codebase I’m new to. But this example really was a me problem, oopsies 🫠

If it’s a C project what’s it using to bring in dependencies? Or did they literally just copy and paste code from different places and there aren’t any dependencies?
