During the long weekend, with the help of Claude I made this skill. It a tool that turns any BJJ instructional videos (almsot, ideally with sound and subtitle) into a cheat sheet so you stop forgetting everything the second you leave the mats. So, if you are using an AI assitant, give it a try. And share me with your feedbacks. Feed it a video with a Youtbe link or bilibili.com and it spits out an illustrated study sheet — step-by-step breakdown, actual freeze-frames of the key positions, notes on what to feel for, and a big "if you only remember ONE thing" callout up top for when your brain is fried after a hard roll. Every step links straight back to the exact timestamp in the video too, so no more scrubbing through 40 minutes trying to find "that one detail on the far-side hook." Works with Claude, Codex, whatever AI you've got — it's just a skill file, drop it in and go. Built it drilling my own instructionals, figured y'all are drowning in the same "I definitely watched a video on this" amnesia.
