Installation Methods

Method 1: Plugin Marketplace (Recommended)

Easiest way - works with claude plugin install:

claude plugin install ThepExcel/thepexcel-claude-plugins

This installs from the thepexcel-claude-plugins repo (auto-synced from this repo).

Method 2: Manual Installation

These skills follow the Open Agent Skills specification and work with multiple AI coding agents.
