SKILL.md

Skills are organized prompts that get loaded on-demand. All prompting best practices apply, with an emphasis on pure XML structure for consistent parsing and efficient token usage.

<quick_start>

  1. Identify the reusable pattern: What context or procedural knowledge would be useful for similar future tasks?
  2. Create directory and SKILL.md:
    • Directory name: Follow verb-noun convention: create-*, manage-*, setup-*, generate-* (see references/skill-structure.md for details)
    • YAML frontmatter:
      • name: Matches directory name, lowercase-with-hyphens, max 64 chars
      • description: What it does AND when to use it (third person, max 1024 chars)
  3. If skill requires API credentials: See references/api-security.md for credential setup
  4. Write concise instructions: Assume Claude is smart. Only add context Claude doesn't have. Use pure XML structure.
  5. Test with real usage: Iterate based on observations.
