What are the requirements for a Claude Code Skill?

A Skill requires an SKILL.md file with specific frontmatter including a name (lowercase-hyphenated), a description (what and when), and optional allowed-tools.

How do I start a new Claude Code plugin?

You can use the `/plugin-development:init ` command to automatically scaffold the required directory structure and metadata files.

How do I ensure my plugin.json is correct?

Run the `/plugin-development:validate` command to perform comprehensive schema and structure checks against the canonical plugin requirements.

How can I add a custom slash command to my plugin?

Use the `/plugin-development:add-command ` playbook to create the command file with the correct frontmatter and template.

How do I test my plugin locally?
