# 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.

This skill's `references/skill-authoring-guide.md` is the procedural HOW-TO companion.
