Today I built my first custom Claude Code skill — infographic-maker. It takes a simple prompt like “Make an infographic about the water cycle” and creates an educational infographic with research, visuals, and a final PNG output. One thing I learned was that the first version wasn't exactly what I wanted. It was a little too text-heavy, so I gave Claude feedback to make it more visual, improve the layout, add a clear water-cycle flow, and verify the information and sources. After a few rounds of testing and feedback, the result was much cleaner and more polished. It was really interesting to see how much the skill improved just by giving it better feedback. Excited to keep building more skills!
