Claude Skills

A collection of open-source Claude Code skills for everyday engineering and system tasks.

Skills are reusable instructions, scripts, and references that Claude Code loads on demand to perform specialized workflows.

Available Skills

Skill	Description
mac-cleanup	Comprehensive MacBook cleanup, disk analysis, and system health audit. Read-only analysis followed by interactive, approval-gated cleanup.

Installation

Skills live in ~/.claude/skills/. Install one by copying or symlinking it:

# Clone the repo
git clone https://github.com/FournineCS/claude-skills.git
cd claude-skills

# Symlink a skill (recommended — get updates with git pull)
ln -s "$PWD/skills/mac-cleanup" ~/.claude/skills/mac-cleanup

# Or copy it
cp -R skills/mac-cleanup ~/.claude/skills/mac-cleanup

Restart Claude Code or start a new session — the skill will be auto-discovered and listed in the available skills.

Using a Skill

Skills auto-trigger on relevant prompts (e.g. "clean up my Mac", "free up disk space"), or you can invoke one explicitly via the / menu.
