Skills, agents, and hooks should be created via plugin-dev plugin,
not generic "tell Claude" or manual file writing.
Example 14: /agent-development for agents, /skill-development for
pipeline skills, /hook-development for hooks, /skill-reviewer for
quality checks, /plugin-validator for setup validation. plugin-dev
added as prerequisite.
GETTING-STARTED.md: /skill-development for skill creation,
/skill-reviewer for iteration, /mcp-integration for MCP servers.
