  "account": "Six months ago, discovering a Claude agent skill was a cumbersome process involving fourteen GitHub tabs. Skills were scattered across various repositories, community forks, and different folder structures. The skills were often poorly described, broken, or difficult to understand without reading the SKILL.md file line by line. To address this issue, I indexed all the skills, classifying, describing, and making them downloadable from a single page. The ecosystem of Claude agent skills consists of five primary problem-solving categories: document manipulation, codebase navigation, external tool orchestration, content production in a fixed house style, and data extraction and transformation. Most skills fall into one of these five categories. A skill's description field plays a crucial role in determining when and how the skill is loaded by the model. An effective description should explicitly mention trigger conditions, file extensions, and user requests. Skills that provide clear trigger conditions are more likely to work effectively. Most skills in the index either have overly narrow or overly broad descriptions, resulting in the skill never firing or firing on every task, respectively. Skills that bundle a working script with the instructions perform better than those that rely solely on prose instructions. A skill that front-loads all the information into SKILL.md consumes more tokens and provides less context to the model when needed. Instead, skills should progressive disclose information in layers, with the description loaded by default, the body loaded when the skill triggers, and reference files loaded only when required.",
  "summary": "Six months ago, finding a Claude agent skill meant opening fourteen GitHub tabs. You'd start at Anthropic's own repository, then follow a link from someone's post to a community fork, then another fork of that fork. Half the skills had no description. A quarter were broken. And every one of them lived in a different folder structure, so you couldn't tell what a skill did without reading its…",
