Skill Creator

If you're building skills for Claude, this is your starting point. It walks through the core principles: keep things concise since context window is shared, match specificity to how fragile the task is, and use progressive disclosure so Claude only loads what it needs when it needs it. The structure is clear: required SKILL.md with frontmatter and instructions, optional scripts for deterministic code, references for documentation Claude can pull in later, and assets for output files. The progressive loading pattern (metadata always present, body when triggered, resources on demand) is smart and the guidance on what not to include (no READMEs, no changelogs) keeps things lean. Practical advice throughout on splitting large skills and avoiding context bloat.
