If you're building skills for Claude and want to understand the structure, this is meta but practical. It walks you through the anatomy of a skill package, from the SKILL.md format to how context windows should be treated as shared resources. The core principle is ruthless concision, which is solid advice given how easy it is to bloat prompts. With over a thousand GitHub stars and 131 installs, it's clearly resonating with people who are either creating their first skill or trying to understand the framework better. Think of it as documentation that doubles as a template, useful when you're staring at a blank file wondering what actually needs to be in there.
