name: skill-install description: Install Claude skills from .skill files. Use when installing a new skill provided by the user as a .skill file (which is a zip archive containing the skill directory structure).

Skill Installation

Installation

Extract the .skill file to ~/.claude/skills/:

Copyunzip skill-name.skill -d ~/.claude/skills/

The .skill file is a zip archive containing a directory with the skill name (e.g., skill-name/), which includes SKILL.md and optional bundled resources.

Post-Installation Behavior

After installation:

1. Read frontmatter only: Load and read the YAML frontmatter from the skill's SKILL.md to understand its name, description, and when to use it. This is essential metadata for knowing the skill's capabilities.

2. Lazy-load body: Do NOT read the full body of SKILL.md or any bundled resources at this time. Only load these when the skill actually triggers for a relevant task.

This progressive loading approach minimizes context usage while ensuring new skills are available when needed.
