No, Martin Eberhard and Marc Tarpenning did not make the Model Y. They left the company more than a decade before. Neither did they make the Model 3, nor the Model S before that. They didn't even make it to the first delivery of Tesla's first car, the Roadster. Your implication that they deserve credit for two decades' worth of Tesla's achievements after they left is plainly ridiculous.
LOL this comes up every single time. Tesla was nothing, it was a name and a plan. They had absolutely 0 and statistically would have never done anything.
Ya'll need to stop with what the founders accomplished pre-Musk.
I have never owned, nor have any desire to ever own a Tesla or any electric car yet, but this sideline war is amusing to see.
I try to keep agents/Claude.md as tiny as possible. With high level "truths" that don't change. Stack used, invariants, file structure, and some scripts.
Skills are more for things you do often. I run mutation tests, type check,linting,etc. I _could_ just prompt and copy/paste the same prompt each time I need to, or I can just run /tests.
I also have skills for specialized tasks I need every once in a while, like a ux skill, a text skill optimized for xyz, etc.
The actual founders of Tesla did; Elon did not.
In case people didn't know already, he was not a founder, he bought the company and demanded the title as part of the purchase.
