Create a new skill for the user.

Instructions

Determine save location: Check whether the first argument token equals global.
- If it does, save to ~/.claude/skills/<skill-name>/SKILL.md, and treat the remaining tokens as the skill description.
- Otherwise, save to ./.claude/skills/<skill-name>/SKILL.md (project scope), and treat all tokens as the skill description.
The command name comes from the directory name (my-skill/ → /my-skill), not from the name field.
Decide the skill type — this drives the frontmatter:
- Reference skill (conventions, domain knowledge, style guides): loaded inline alongside the conversation. Leave it model-invocable.
- Task skill (deploy, commit, codegen, multi-step actions): add disable-model-invocation: true so it only runs as /name and Claude never fires it on its own — especially for anything with side effects.
Gather information (use arguments if provided, otherwise ask):
- Skill name (directory name → the command)
- Description (most important — see the rule below)
- Body / instructions
- Any optional frontmatter the skill actually needs (see reference.md)
