Agree with this, the "find this thing in my spaghetti codebase" is far and away the best use of LLMs I've seen. Fill in the rest of this switch statement, populate this struct from this database call, etc. also work pretty well. I would love if I could get a small model that ran locally that was able to pull off those 2 tricks. Explaining code works sometimes, but even the biggest models are still prone to getting confused and/or making stuff up that isn't there. I don't like the agentic features at all and expect these to mostly die because they're expensive and, IMO, only provide the illusion of productivity.
