cesium-context7

cesium-context7 is a skill for Claude Code, Codex from CesiumGS/cesium-ai-integrations. It costs 188 tokens per session (791 once invoked), scanned A, original, Apache-2.0.

A documentation lookup tool for Cesium, a platform for displaying 3D maps and geospatial data in web, Unity, and Unreal Engine projects. It retrieves current Cesium documentation before code is written or explained.

In plain words
What is it for?
Use it to look up CesiumJS classes, 3D Tiles, georeferencing, viewer setup, and Cesium integrations for Unity or Unreal Engine.
Why use it?
It helps avoid relying on outdated or incorrect information about Cesium APIs and integrations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cesium-context7 scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Context7 for Cesium Development

This skill provides access to up-to-date Cesium documentation for CesiumJS, Unreal Engine integration, and Unity integration.

When working with Cesium-related code, use Context7 MCP Server tools to fetch current documentation before providing answers or generating code.

Available Tools

1. resolve-library-id

Search for libraries and retrieve their Context7 library IDs.

⚠️ Only use this tool when it's unclear which library to use. For Cesium projects, use the Known Library IDs listed below.

Parameters:

  • libraryName (string, required): Name of the library to search
  • query (string, optional): Additional search context

Example use case: Find the correct library ID for an unfamiliar library or when the library ID is unknown.

2. query-docs

Retrieve documentation for a specific library and query.

Parameters:

  • libraryId (string, required): Context7 library ID
  • query (string, required): Documentation query or topic
  • version (string, optional): Specific library version

Example use case: Get documentation for Cesium Viewer initialization using library /cesiumgs/cesium.

Known Library IDs

CesiumJS API Documentation

For class constructors, methods, and properties (e.g., Viewer, Entity, Cartesian3, Camera methods, Scene properties):

  • Library ID: /cesiumgs/cesium

Cesium for Unreal Engine

For Unreal Engine integration (e.g., ACesium3DTileset, ACesiumGeoreference, Blueprint integration):

  • Library ID: /cesiumgs/cesium-unreal

Cesium for Unity

For Unity integration (e.g., Cesium3DTileset component, CesiumCameraController, C# scripting):

  • Library ID: /cesiumgs/cesium-unity

3D Tiles Specification

For tile formats and schema details (e.g., tileset JSON structure, refinement strategies, metadata schemas):

  • Library ID: /websites/ogc_cs_22-025r4

Usage Guidelines

  • Use the Known Library IDs listed above for Cesium-related queries
  • When a question requires information from multiple sources (e.g., CesiumJS API + 3D Tiles spec, or Unreal integration + CesiumJS concepts), make separate query-docs calls with different library IDs to gather comprehensive documentation
  • Use resolve-library-id when the library is unknown, not listed in Known Library IDs, or when it's unclear which library best fits the question
  • Use query-docs to fetch documentation before generating code to ensure accuracy
  • Specify the version parameter when working with a specific version
  • Provide clear, specific queries to get the most relevant documentation
  • Avoid hallucinations by using current, version-specific documentation

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
