How it works

build-a-skill

When your agent uses it

Interactive tutorial that walks the user through designing, writing, testing, and distributing their own Skill for Claude. Use when the user says "teach me how to build a skill", "help me make a skill", "walk me through skill creation", "I want to learn skills", "/build-a-skill", or asks about SKILL.md structure, YAML frontmatter for skills, progressive disclosure, skill distribution, or how to package a workflow as a reusable skill. Covers fundamentals, planning, technical requirements, instruction writing, testing, distribution, and common patterns.

Token counts are estimates. Scripts run separately; they are not counted as reference context.

The playbook

  1. Operating principles for this tutorial
  2. The interactive flow
  3. Troubleshooting during the tutorial
  4. Important things you must NOT do
  5. Quick map of reference files
