What it does

CLI Hub Matrix 3D Cad is an agent skill from HKUDS/CLI-Anything. Capability-based multi-tool matrix for 3D modeling, CAD, point clouds, rendering, GPU debugging, and fabrication. Covers mesh/parametric/photogrammetry and the path from idea to printed part or game-ready asset.

Its SKILL.md is about 2.4k 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 Python and Blender. The repository describes itself as: "CLI-Anything: Making ALL Software Agent-Native" -- CLI-Hub: https://clianything.cc/. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve 3D graphics and WebGL

Example prompts

  • “/cli-hub-matrix-3d-cad”

Requirements

  • Python 3
  • A credential in POLYCAM_API_KEY
  • A credential in LUMA_API_KEY

Workflow steps

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

  1. Use preflight as an availability report, not as a provider selector.
  2. Treat provider order as documentation order only.
  3. Choose from user requirements, output quality bar, offline needs, credential state, install cost, and provider notes.
  4. Escalate to paid or metered APIs only when credentials are already present or the user explicitly consents.

What it can do on your machine

Read from SKILL.md and the folder at commit 34f5195. 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:

    • python

    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 these keys or tokens, usually read from environment variables:

    • LUMA_API_KEY
    • ONSHAPE_ACCESS_KEY
    • FUSION360_TOKEN
    • POLYCAM_API_KEY
    • OCTANE_TOKEN

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

Context cost

CLI Hub Matrix 3D Cad loads about 2.4k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 850 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k

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.

Capability-based multi-tool matrix for 3D modeling, CAD, point clouds, rendering, GPU debugging, and fabrication. Covers mesh/parametric/photogrammetry and the path from idea to printed part or game-ready asset.

3D & CAD Matrix (S3 — v2 capability-based)

Scenario S3. Strongest technical scenario in the matrix by depth — Blender + FreeCAD + CloudCompare + RenderDoc is rare coverage. Structural gaps: texturing and fabrication slicing.

Schema: docs/cli-matrix/matrix_registry.schema.md. Matrix plan: docs/cli-matrix/cli-matrix-plan.md.

Install

bash
cli-hub matrix install 3d-cad
cli-hub matrix info    3d-cad
cli-hub matrix preflight 3d-cad --json

Provider selection constraints

  1. Use preflight as an availability report, not as a provider selector.
  2. Treat provider order as documentation order only.
  3. Choose from user requirements, output quality bar, offline needs, credential state, install cost, and provider notes.
  4. Escalate to paid or metered APIs only when credentials are already present or the user explicitly consents.

Offline context? Most of this matrix is offline-first; rendering and photogrammetry are the exceptions.


Preflight

Run cli-hub matrix preflight 3d-cad --json first. Use the manual block below for extra probes or older cli-hub versions.

bash

Recipes

  • printable-part — parametric CAD → mesh → slice → gcode. Uses: model.parametric, model.mesh, fabricate.slice.

  • game-asset — model → texture → export to engine. Uses: model.mesh, material.texture, export.engine, (optional render.preview).

  • reality-scan — photos → photogrammetry → clean mesh → export. Uses: photogrammetry.reconstruct, pointcloud.process, model.mesh, export.engine.

  • cnc-part — parametric part → CAM toolpath → gcode. Uses: model.parametric, fabricate.cam.

  • product-viz-still — CAD → import → scene → offline render. Uses: model.parametric, model.mesh, material.texture, render.offline.

  • gpu-bug-repro — capture frame → analyze → patch shader. Uses: gpu.debug, render.preview.


Known gaps

  • material.texture — no open equivalent to Substance; Blender shader nodes are the current ceiling.
  • fabricate.slice — PrusaSlicer/Cura natives work but want a harness-level wrapper.
  • model.sculpt — impractical for agents today.
  • Unity / Unreal export — only Godot covered on the harness side.

Agent guidance

  • Parametric first, mesh later. Start in model.parametric when the object has dimensions; model.mesh when it's organic.
  • Always bake before export. When handing off to export.engine, apply modifiers and bake materials — runtime engines don't read Blender shader graphs.
  • Check manifold before slicing. fabricate.slice fails silently on non-manifold meshes; use trimesh.Trimesh.is_volume or pymeshlab's manifold check first.
  • Offline-capable baseline. This matrix is highly offline-capable — API escalation is rarely needed except for photogrammetry-at-scale.
  • Workspace discipline. Keep .FCStd / .blend / .ply / .stl / .gcode in one project folder so the chain of transformations is reproducible.
