What it does
Obj Exporter is an agent skill from benchflow-ai/skillsbench. Three.js OBJExporter utility for exporting 3D geometry to Wavefront OBJ format. Use when converting Three.js scenes, meshes, or geometries to OBJ files for use in other 3D software like Blender, Maya, or MeshLab.
Its SKILL.md is about 510 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 3D graphics and WebGL. It works with Three.js and Blender. The repository describes itself as: SkillsBench evaluates how well skills work and how effective agents are at using them. The licence is Apache-2.0.
When your agent uses it
- Converting Three.js scenes
- Geometries to OBJ files for use in other 3D software like Blender
Example prompts
- “/obj-exporter”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 9a1f4dd. 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 (its code samples are javascript and json).
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
Obj Exporter loads about 514 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 41 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.
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.

OBJExporter Guide
Basic Structure
OBJ is a text-based 3D geometry format:
# Comment
v x y z # Vertex position
vn x y z # Vertex normal
f v1 v2 v3 # Face (triangle)
f v1/vt1/vn1 v2/vt2/vn2 v3/vt3/vn3 # Face with texture/normal indicesExample:
# Cube
v 0 0 0
v 1 0 0
v 1 1 0
v 0 1 0
f 1 2 3
f 1 3 4Three.js OBJExporter
Three.js provides OBJExporter in examples:
import { OBJExporter } from 'three/examples/jsm/exporters/OBJExporter.js';
const exporter = new OBJExporter();
const objString = exporter.parse(object3D);
// Write to file (Node.js)
import fs from 'fs';
fs.writeFileSync('output.obj', objString);Exporting with World Transforms
To export geometry in world coordinates:
// Update world matrices first
root.updateMatrixWorld(true);
// Clone and transform geometry
const worldGeometry = mesh.geometry.clone();
worldGeometry.applyMatrix4(mesh.matrixWorld);
// Create new mesh for export
const exportMesh = new THREE.Mesh(worldGeometry);
const objData = exporter.parse(exportMesh);Merging Multiple Geometries
import { mergeGeometries } from 'three/examples/jsm/utils/BufferGeometryUtils.js';
const geometries = [];
root.traverse((obj) => {
if (obj instanceof THREE.Mesh) {
const geom = obj.geometry.clone();
geom.applyMatrix4(obj.matrixWorld);
geometries.push(geom);
}
});
const merged = mergeGeometries(geometries);
const mergedMesh = new THREE.Mesh(merged);
const objData = exporter.parse(mergedMesh);Node.js ES Module Setup
For running Three.js in Node.js:
// package.json
{ "type": "module" }// script.js
import * as THREE from 'three';
import { OBJExporter } from 'three/examples/jsm/exporters/OBJExporter.js';© benchflow-ai, Apache-2.0. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file
