Description

Agent skills for building ServiceNow applications using ServiceNow Fluent, a TypeScript-based DSL for defining platform metadata in code. These skills teach Copilot how to use the @servicenow/sdk CLI to look up API types, metadata conventions, and project structure before generating or editing code.

Includes two skills: now-sdk-explain, which fetches live SDK documentation via npx @servicenow/sdk explain and triggers automatically when working in a Fluent project; and now-sdk-setup, which validates that Node.js 20+ and @servicenow/sdk v4.6.0+ are configured correctly.
