Unreal Modeling Primitives is an agent skill from Italink/UnrealClientProtocol. GeometryScript 图元创建与建模函数。当用户要求创建 Box、Sphere、Cylinder 等基础形状,或进行拉伸、旋转体、壳体等建模操作时使用。
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Game Development, covering Game development. The repository describes itself as: Lightweight UE5 plugin that exposes Unreal Engine's reflection system over TCP+JSON — let AI agents call UFunctions, read/write UProperties, and inspect any UObject in a running… The licence is MIT.
Read from SKILL.md and the folder at commit 7f0a56e. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Unreal Modeling Primitives loads about 1.7k tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 392 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Unreal Modeling Primitives fits situations like: tasks that involve Game development.
Run `npx skills add Italink/UnrealClientProtocol --skill unreal-modeling-primitives -a claude-code`. Or copy the skill folder (Skills/unreal-modeling-primitives in Italink/UnrealClientProtocol) into .claude/skills/unreal-modeling-primitives in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Italink/UnrealClientProtocol --skill unreal-modeling-primitives -a codex`. Or copy the skill folder (Skills/unreal-modeling-primitives in Italink/UnrealClientProtocol) into .agents/skills/unreal-modeling-primitives in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Italink/UnrealClientProtocol --skill unreal-modeling-primitives -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/unreal-modeling-primitives, .gemini/skills/unreal-modeling-primitives, .github/skills/unreal-modeling-primitives and .opencode/skills/unreal-modeling-primitives in your project.
SKILL.md names no scripts, command-line tools or credentials: Unreal Modeling Primitives is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Unreal Modeling Primitives is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.7k tokens (SKILL.md is roughly 6.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
