Vibe coding best practice for cesiumjs

We’ve recently launched a new repository for Cesium + AI integrations:
GitHub - CesiumGS/cesium-ai-integrations · GitHub .
Our goal is to provide examples and resources that help developers use Cesium effectively with AI.

To reduce hallucinations when working with Cesium APIs, we’ve also created a guide on how to use the Context7 MCP server to fetch official Cesium documentation:

# 🌐 Context7 Integration Guide for Cesium

## 📖 Overview

[Context7](https://context7.com/docs/overview) is an MCP (Model Context Protocol) server that provides real-time access to up-to-date library documentation and code examples directly to AI coding assistants. It retrieves current documentation from source repositories instead of relying on potentially outdated LLM training data.

**Repository**: https://github.com/upstash/context7

## 💡 Why Context7 for Cesium Development

AI assistants often hallucinate non-existent APIs, incorrect parameters, and obsolete patterns when working with Cesium due to outdated training data. Context7 solves this by fetching current, version-specific documentation in real-time.

## 📚 Already Indexed Documentation/Website

The following Cesium-related documentation sources are available through Context7:

| Documentation              | Original                                                          | Context7                                                                 | Context7 Library ID               |

Additionally, we’ve published a skill that helps AI assistants interact with the Context7 MCP server:
