Is the Cesium Context7 skill free?

Yes. The skill itself is free from CesiumGS/cesium-ai-integrations. SkillProof publishes the install command and an independent test verdict at no cost.

How do I install Cesium Context7?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Cesium Context7 with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Didn't pass
Tested: Jul 18, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 30, 2026 · ac05d3a

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 18, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

Install verified verbatim from a clean HOME with no ~/.claude. The skill is a thin pointer that hands Cesium doc lookups to the Context7 MCP using four pre-pinned library IDs, so its whole payoff depends on that MCP being installed. With no Context7 MCP available the up-to-date-docs benefit could not be exercised and no delta over a no-skill baseline was shown. Body is clean and honest, but it only earns its keep once Context7 is wired up.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

Installs cleanly 5/5
Triggers reliably 5/5
Output vs. baseline 3/10
Docs & honesty 4/5

What Cesium Context7 does

Routes Cesium documentation lookups through the Context7 MCP server, supplying four pre-pinned library IDs for CesiumJS, Cesium for Unreal, Cesium for Unity, and the 3D Tiles spec. Triggers when writing or debugging CesiumJS, Unreal/Unity Cesium integrations, or 3D Tiles code so the agent pulls version-current API docs instead of hallucinating.

How to install Cesium Context7

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
