pforret/cli-skills

A plugin marketplace for Claude Code — CLI-based skills wrapping popular tools.

Installation

Step 1: Add the marketplace

/plugin marketplace add pforret/cli-skills

Step 2: Install a plugin

/plugin install screenshot-web@cli-skills
/plugin install screenshot-desktop@cli-skills
/plugin install markdown-web@cli-skills
/plugin install markdown-file@cli-skills

Step 3: Run setup

Each plugin has a setup.sh that installs dependencies. Run it once before first use. Claude will do this automatically when the skill is invoked.

Option A — Python venv (default):

bash setup.sh

Option B — Docker (no Python/venv needed):

bash setup.sh --docker

Each plugin also has a run.sh wrapper that auto-detects whether to use Docker or venv, so you don't need to remember which mode you installed with.
