How do trigger phrases work in skills?

Trigger phrases are defined in the metadata description of a SKILL.md file; when a user mentions these keywords, Claude loads the relevant skill content into its context.

Can I define custom lifecycle hooks?

Yes, you can configure hooks.json to trigger specific prompts or validations at events like SessionStart, PreToolUse, and PostToolUse.

What is progressive disclosure in Claude Code?

It is a performance optimization technique that loads small metadata first, then the core skill content, and finally detailed references only as needed by the AI.

What is a Claude Code plugin?

A plugin is a specialized package containing skills, commands, agents, and hooks that extend Claude's native capabilities to handle specific domains or workflows.
