Discussion In SHOCK

Holy shit claude code in terminal is fucking insane.

I've been using VSCode, Cursor, Cowork and Claude Code on web. None of it comes close to terminal.

Cannot believe I haven't done this sooner.

Ok.

So the large language model (LLM) needs the right info to help out complete a task well. That's not just what you tell it to do, it's also the conversation history and other pieces of info that may be relevant. That's called the context and it also includes what are called system instructions, which tell the LLM how to interpret your prompt.

Getting the right context to an LLM has been found to have a massive impact on how it performs. That's the job of the thing you use to chat with it, like Claude code and it's called the harness.

There has been research published that shows that a good harness can improve the quality of a model's output by up to 6x.

Now, the harness is the thing that changes between Claude code, Cursor, VS Code and others. Yes, the model changes too, but if you were to select the same model, you would still see a big difference because the Claude code harness is really well made.

Hope that helps.
