Looker Developer Skills Repository

This repository contains a collection of "skills" designed to assist AI agents and developers in writing high-quality, standardized LookML code. Each skill encapsulates specific instructions, best practices, and examples for different aspects of Looker development.

Installation & Usage

To use these skills in your own projects—especially to enhance AI assistants like Gemini, Cursor, Antigravity, or Claude Code—we recommend adding this repository to your project.

Installation via npx skills add (Recommended)

The skills CLI is a tool used to install and manage specialized instructions (skills) for AI agents in your workspace. To install these LookML skills in your project, use npx skills add.
