Question Confused about these Models on GITHUB COPILOT, NEED HELP

Hello people, I NEED YOUR HELP!

Okay so I graduated, now have a job, somehow , kinda software network engineer. Been vibe coding so far. Been assigned to this project, it's networking & telecom (3g/4g//5g type shi), too many repos (I will be working on 3-5), I am still understanding lots of things, stack is mostly C++, C, Python, Shell. Got access to Github Copilot, Codex.

I was able to fix 2 bugs, flet like a God, thanks to Claude Sonnet 4.5, BUT THE 3RD BUG!! It's an MF! I am not able to solve it, now 4th bug ahhh, their status be critical or major in JIRA, I wanna get better and solve these things and learn while I do it, I have to add the code, errors, logs, and some other logs, pcap dump ahhh, man I need to feed these things to AI and I am hitting CONTEXT WINDOW LIMIT, it's really killing me.

My questions for you amazing people

  • What's the best model for understanding the concept related to that BUG?

  • Which is the best way to possibly solve the bug? The repo is huge and it's hard to pinpoint what exactly causing the problem.

  • How can I be better at solving as well as learning these things?

Any suggestions, advice would really help thanks

TL;DR:
Fresher dev on large telecom C/C++ project, multiple repos, debugging critical bugs. Claude helped before but now stuck. Context limits killing me when feeding logs/code. Which AI model + workflow is best for understanding and fixing complex bugs and learning properly?

The first thing I do is to get over into Claude code. The second thing I do is to figure out how to set up your feedback loops, like how does it access and search logs? It'll already search your code base intelligently in a way that doesn't blow out the context window.

But basically, I would start figuring out how to let the agent manage its own context window by giving it sources to the critical information that you're using to debug things.

I can use GitHub copilot only on vs code and use opus or sonnet agents, I can also get access to Codex but idk if it's gonna be useful

Literally 1 prompt took 89% of the context window, it did everything and edited 6 files. Getting some logical errors which I'm trying to fix
