I feel there’s a lot of marketing and pure bullshit around LLMs configuration and conventions.

Law of diminishing returns applies here perfectly - you can learn prompting in 2 hours and get 400% performance boost or spend weeks on subagents and skills and Opus and st best it’s another 50% boost but not really - in my case in a good day Sonnet is a genius and on a bad one Opus is an moron. One day the same query consumes 6k tokens, the next 700k.

They want to get you hooked and need to show investors they’re super busy but in fact it’s mostly smoke and mirrors. And prompting, once you learn to give proper context, is far from rocket science.
