Generate 3D Model

What it does

When your agent uses it

• The user want to generate
• Forge a 3D model
• Prop from a text description — make a 3D model of a robot
• Generate a GLB of a sword

Example prompts

• “make a 3D model of a robot”
• “generate a GLB of a sword”
• “I need a 3D chair”
• “/generate-3d-model”

Workflow steps

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

1. 1Give the user the viewer link — they can rotate and inspect the model in the
2. 2Give the glbUrl for download / import into Blender, Unity, three.js, etc.
3. 3If they want it animated, feed glbUrl into the rig-a-model skill.

What it can do on your machine

Read from SKILL.md and the folder at commit 238ef60. 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

  Shell commands in SKILL.md call:

  • curl

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

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • three.ws

  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

Generate 3D Model loads about 1k tokens when it runs. Until then it costs about 100 tokens; SKILL.md has 410 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~100

When it runs · the whole SKILL.md, loaded when a task matches

~1k

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

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.

name

generate-3d-model

description

Turn a text prompt into a downloadable, textured 3D model (GLB). Use when you or the user want to generate, create, make, or forge a 3D model, asset, object, mesh, or prop from a text description — "make a 3D model of a robot", "generate a GLB of a sword", "I need a 3D chair". Runs on the FREE text→3D lane (no key, no account, free). Returns a GLB URL plus a browser viewer link.

when_to_use

User wants a 3D object/asset/prop from text. For a posable character with a skeleton, use create-3d-avatar. To rig an existing GLB, use rig-a-model.
