If you're building skills for Claude, start here. This walks you through the complete architecture: how to structure SKILL.md with frontmatter and instructions, when to bundle scripts versus references versus assets, and how to use progressive disclosure so you're not burning context tokens on stuff Claude doesn't need yet. The core insight is treating skills like onboarding docs, not documentation dumps. It's opinionated about keeping things concise (context window is a public good) and matching specificity to fragility. Includes concrete patterns for splitting large skills across files and explains the three-level loading system that makes the whole thing work without bloating every conversation.
