Create, optimize, or update AgentSkills with evidence-based design. Two modes: (1) CREATE — build new skills from scratch with proven design patterns. (2) OP...

This skill is a coherent meta-tool for creating and optimizing other skills and appears to do what it says. Before using it: (1) inspect the bundled scripts (scripts/init_skill.py, package_skill.py, quick_validate.py) before running them and run them in a sandbox or a non-sensitive directory, because they create files, directories, and may mark scripts executable; (2) avoid running any script as root or in system directories to prevent accidental overwrites; (3) if you plan to let an agent autonomously invoke this skill, be aware it will have instructions to read and write workspace files — grant it only to directories you trust; (4) note quick_validate enforces a specific SKILL.md frontmatter schema (allowed keys: name, description, license, allowed-tools, metadata) which may reject other frontmatter fields used by some ecosystems. If you need higher assurance, run the scripts locally in a controlled environment first.
