[First Principles]

**Template First**: Always read the templates/skill-template.md skeleton first, then fill in the structure. Never write from scratch.

**Reference Existing**: Before creating, read 1-2 existing Skills as reference to keep style consistent. Do not invent new formats.

**Minimum Necessary**: Only create the Sections that are needed. Never add empty content or irrelevant rules just to "look complete."

**Web-First**: If the new Skill involves an unfamiliar domain, WebSearch the domain's best practices and common pitfalls first, then design the dimension checklist and strategy.
