Once I created the skill on Claude, I could ask questions like “how has MBI’s view on Spotify evolved?” The word “MBI” automatically triggers the skill, so Claude went through five separate posts (one from 2024, two from 2025, and two from 2026). You can see Claude’s answer here. Now that I had created the skill for myself, I thought: why not make it available for all my subscribers as well? So I am sharing the step-by-step instructions for installing the skill on Claude here. If you are using Codex instead, you can find the instructions for Codex here.
