Skill Creator

This is meta tooling for building skills themselves. It walks you through the structure of a SKILL.md file, explains the three-level loading system (metadata, instructions, bundled resources), and pushes hard on keeping things concise since context window is shared across everything. The core insight is treating skills like onboarding guides that give agents procedural knowledge they can't have from training alone. Heavy emphasis on progressive disclosure: put only essentials in the main file, split detailed references and framework-specific docs into separate files that get loaded on demand. Useful if you're publishing skills or building internal tooling and want to understand the design philosophy behind keeping agents focused without bloating context.
