The previous version incorrectly recommended XML tags for skill body content.
Anthropic's official specification uses standard markdown headings.
Changes:
- SKILL.md: Complete rewrite using markdown format, not XML tags
- Added references/official-spec.md from code.claude.com/docs/en/skills
- Added references/best-practices.md from platform.claude.com
- Removed obsolete use-xml-tags.md
- Updated naming to gerund form (creating-agent-skills)
- Descriptions now third person with "what" and "when"
BREAKING: If you followed the old XML tag guidance, convert to markdown headings.
