@deobald we will only write these (often quite good-for-humans-to-read) SKILL.md documents for our Lord and Saviour Piles of Linear Algebra the same way we'll only build public transit when someone is angling for the Olympics to descend on their town, and like, I'm so generally disappointed in us but at least when the last graphics card has been burned out and it all goes dark maybe we still have a few SKILL.md printouts around.
