description: "Authoritative guide on how to architect, format, and structure new Anthropic Progressive Disclosure skills. Triggers: Use before creating OR modifying any .agents/skills/**/*.md files — Progressive Disclosure architecture (Map vs World Atlas), YAML frontmatter, skill structure. Complementary to turn-memory-pre-flight (load-runtime-effect dimension vs skill-shape dimension)."
Skill Creation Framework
If you are tasked with creating a new Agent Skill, you MUST immediately use the view_file tool to read and strictly adhere to .agents/skills/create-skill/references/skill-authoring-guide.md before creating any files. This prevents system prompt bloat and ensures future agents can parse your skill correctly.
