Create Skill

An Agent Skill is a self-contained capability bundle: a directory with a SKILL.md (this format), optional supporting prompts, and a samuel-plugin.toml manifest used by the loader.

This built-in walks the user through the four decisions that make a skill load cleanly in Samuel v2:

1. Name — kebab-case, unique under the registry
2. Description — one-paragraph "what + when" used by the loader to surface the skill in matching prompts
3. Capabilities — declared permissions (fs:read, net:none, …)
4. Manifest — samuel-plugin.toml with kind = "skill"
