Skills Support for Plugins

What: Plugins can now include "skills" - reusable AI behaviors defined in markdown files that can be loaded and executed by Claude Code.

How to use:

# Create a skills directory in your plugin
~/.claude/plugins/my-plugin/skills/my-skill/SKILL.md

# Or specify custom paths in your plugin manifest
{
  "name": "my-plugin",
  "skills": ["custom-skills-dir", "another-skills-dir"]
}

Details:

• Skills are loaded from subdirectories containing SKILL.md files
• By default, looks for a skills/ directory in your plugin root
• Custom paths can be specified in the plugin manifest using the skills field (single path or array)
• Each skill directory should contain a SKILL.md file with frontmatter and content
• Skills are processed similarly to commands and agents but with isSkillMode: true
• Evidence: hMB() at line 422839, skillsPath property at line 377365, isSkillMode flag at line 422855
