What it does

Unreal Modeling Create is an agent skill from Italink/UnrealClientProtocol. Create geometry through the GeometryScript modeling workflow. Use when the user asks to create primitives, generate profile-based shapes, or produce mesh assets or working meshes for downstream pipelines.

Its SKILL.md is about 710 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.

When your agent uses it

  • The user asks to create primitives
  • Generate profile-based shapes
  • Produce mesh assets
  • Working meshes for downstream pipelines

Example prompts

  • “/unreal-modeling-create”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. create a working mesh
  2. call a primitive append function on the working mesh
  3. if needed, continue into meshops / deform / UV steps
  4. only write back if asset output is required

What it can do on your machine

Read from SKILL.md and the folder at commit 7f0a56e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Unreal Modeling Create loads about 706 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 305 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~706

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.

Safety

Auto-check passed

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.

description
Create geometry through the GeometryScript modeling workflow. Use when the user asks to create primitives, generate profile-based shapes, or produce mesh assets or working meshes for downstream pipelines.

Modeling — Create

Prerequisite: read unreal-modeling-core first.

Goal

Use this skill when the output should be one of the following:

  • a transient working mesh for further processing
  • a static mesh asset updated from generated geometry
  • a new geometry result that will be consumed by a higher-level pipeline

Required decision rules

If the user wants a new mesh to be processed later

Stop at the working mesh stage unless asset output is explicitly required.

If the user wants a reusable asset result

Create geometry in a working mesh first, then write it to a static mesh asset.

Standard create workflow

text
CreateWorkingMesh
-> GeometryScript create/modeling functions
-> optional writeback or asset creation
-> optional collision finalization

Primary libraries

  • /Script/GeometryScriptingCore.Default__GeometryScriptLibrary_MeshPrimitiveFunctions
  • /Script/GeometryScriptingCore.Default__GeometryScriptLibrary_MeshModelingFunctions
  • /Script/GeometryScriptingCore.Default__GeometryScriptLibrary_SimplePolygonFunctions
  • /Script/GeometryScriptingCore.Default__GeometryScriptLibrary_PolyPathFunctions
  • /Script/GeometryScriptingEditor.Default__GeometryScriptLibrary_CreateNewAssetFunctions

Recipe: create a primitive working mesh

Use when

You need a box, sphere, cylinder, capsule, cone, disc, or torus as the starting point for later processing.

Steps
  1. create a working mesh
  2. call a primitive append function on the working mesh
  3. if needed, continue into meshops / deform / UV steps
  4. only write back if asset output is required
Output
  • default output: working mesh path
  • asset output only if explicitly requested

Recipe: create profile-based geometry

Use when

You need extrude / revolve / sweep style generation.

Steps
  1. create a working mesh
  2. construct the required polygon/path inputs
  3. call the relevant GeometryScript modeling/path functions
  4. validate geometry
  5. hand off the working mesh or write back

Recipe: create asset output from generated geometry

Use when

The end result must exist as a real mesh asset.

Steps
  1. create and populate a working mesh
  2. optionally preprocess normals / UV / repair
  3. write back to an existing asset or create a new asset
  4. if required, generate collision as a separate finalization step

Common mistakes to avoid

  • writing to assets too early before geometry preparation is complete
  • skipping the working mesh stage
  • combining creation and business-layer policy decisions in the same step
