This is the sharp-bladed axe of reason I've used against all of these massive "prompt frameworks" and "superprompts".

Anthropic's survival depends on Claude Code performing as well as it can, by all metrics.

If the Very Smart People working on CC haven't integrated a feature or put text into the System Prompt, it's probably because it doesn't improve performance.

Put another way: The product is probably as optimized as it can get when it comes out the box, and I'm skeptical about claims otherwise without substantial proof.
