Write A Skill

Meta-programming for Claude agents. Creates properly structured skills with the bundled file organization and progressive disclosure patterns that actually work in practice. Handles the tricky description writing (the trigger text your agent sees when deciding which skill to load), enforces the 100-line SKILL.md limit, and generates the directory structure with separate reference files and utility scripts. Useful when you're building custom capabilities and want to follow established patterns rather than reinventing the wheel. Saves you from the common mistakes like cramming everything into one massive file or writing descriptions too vague for skill selection.
