Skill Development for Claude Code Plugins

Overview

Skills are modular knowledge packages that extend Claude's capabilities with specialized workflows, domain expertise, and bundled resources. They transform Claude from a general-purpose agent into a specialized expert.

Skills use progressive disclosure - a three-level loading system that manages context efficiently:

1. Metadata (name + description) - Always in context (~100 words)
2. SKILL.md body - Loaded when skill triggers (~1,500-2,000 words)
3. Bundled resources - Loaded as needed by Claude (unlimited)
