What skill I built: I initially took the easy road for my first skill and went with the content creator. My wife and I want to get back into consistent content creation, though, so this actually serves a greater need. I titled the skill nutrient-content, and I can either invoke it directly or tell Claude I want to create some content. I can either give it a topic and have it research the topic, or copy-paste a section of text or transcript and have it identify and synthesize the best takeaways for content with the explicit purpose of growing our audience. It will also format it either for X/twitter, an Instagram post or carousel, or an Instagram reel or YouTube short (I'll do the video generation when I have a paid Kie account, keeping it low-cost for now). One optimization I made: I included a few .docx files I have that go over content hooks, viral ideas, etc. I was pleased to see Claude improve the writing. But more so, I was even more impressed to see Claude tell me "a lot of this is generic engagement-bait ("You're NOT going to believe...", "This ONE trick will blow your mind", FOMO, Shock & Awe, tear-jerker emotional hooks). That directly conflicts with brand-voice.md's "no hype, no filler, no fear-based claims" rule, so I'm not adopting those wholesale." THAT'S what made me smile. I also ran into some initial issues with the image generation. Kie wasn't cooperating, and Canva was just downright bad. Finally got Kie working properly, and I'm happy with the initial results. I think I'm going to play around with Day 3 a little more. Two other skills I want to create over the next day or two: 1. a skill that pulls all the mechanistic data from all the functional health conversations Claude and I have, and compiles them into my pre-existing resources to supercharge the knowledge base. 2. a skill that I run weekly to round up and review recent research papers, detailing the key takeaways, coaching applications, personal applications, and content strategies.
