Installation

A skill is a folder with a SKILL.md file. Pick your agent and run the commands in a terminal (macOS, Linux or Git Bash on Windows) from your project root.

Copy the prompt into Claude, Codex or another assistant: it will review the skill and install it for you.

Install the “cli-hub-matrix-3d-cad” skill from mozgi.io (https://mozgi.io/skills/cli-hub-matrix-3d-cad/) for me.

1. Download the archive: https://mozgi.io/skills/cli-hub-matrix-3d-cad/download
   If it fails, take the skill folder from the source: https://github.com/HKUDS/CLI-Anything/tree/main/cli-hub-matrix/3d-cad
2. Read SKILL.md and the other files. Check the skill is safe: no hidden commands, no sending data elsewhere, no scripts doing something other than described. If anything looks suspicious, stop and tell me.
3. Put the “cli-hub-matrix-3d-cad” folder into your agent's skills folder: .claude/skills/ for Claude Code, .agents/skills/ for Codex, .cursor/skills/ for Cursor, .gemini/skills/ for Gemini CLI. Inside the project if we are in one, otherwise in the home folder (~/.claude/skills/ etc.).
4. Make sure <skills folder>/cli-hub-matrix-3d-cad/SKILL.md exists.
5. Briefly tell me what this skill does and offer to try it on my task.

If you cannot do a step yourself, tell me what to click or type.

git clone --depth 1 --branch main https://github.com/HKUDS/CLI-Anything.git /tmp/CLI-Anything
mkdir -p .claude/skills
cp -r /tmp/CLI-Anything/cli-hub-matrix/3d-cad .claude/skills/3d-cad

Restart Claude Code — the skill appears in the list; call it manually with /cli-hub-matrix-3d-cad. For all projects use ~/.claude/skills.

git clone --depth 1 --branch main https://github.com/HKUDS/CLI-Anything.git /tmp/CLI-Anything
mkdir -p .agents/skills
cp -r /tmp/CLI-Anything/cli-hub-matrix/3d-cad .agents/skills/3d-cad

Codex looks for skills in .agents/skills from the current folder up to the repo root; call one with /skills or $cli-hub-matrix-3d-cad. For all projects use ~/.agents/skills.

git clone --depth 1 --branch main https://github.com/HKUDS/CLI-Anything.git /tmp/CLI-Anything
mkdir -p .cursor/skills
cp -r /tmp/CLI-Anything/cli-hub-matrix/3d-cad .cursor/skills/3d-cad

Cursor picks the skill up on start; call it with “/” in Agent chat. Cursor also reads .claude/skills and .agents/skills. For all projects use ~/.cursor/skills.

git clone --depth 1 --branch main https://github.com/HKUDS/CLI-Anything.git /tmp/CLI-Anything
mkdir -p .gemini/skills
cp -r /tmp/CLI-Anything/cli-hub-matrix/3d-cad .gemini/skills/3d-cad

Gemini CLI offers to activate the skill when a task matches — you approve it. For all projects use ~/.gemini/skills.

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

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.

cli-hub list --json
python - <<'PY'
import importlib.util
for m in ("trimesh","pymeshlab","open3d","cadquery","build123d","solid",
          "pygltflib","laspy","pyvista","bpy","rawpy","pycam"):
    print(m, importlib.util.find_spec(m) is not None)

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.

Frequently asked questions

What does the cli-hub-matrix-3d-cad skill do?

A multi-tool for 3D modeling, CAD, point clouds, rendering, and GPU debugging, covering the entire path from idea to finished asset.

How do I install cli-hub-matrix-3d-cad?

Open the “Installation” block on this page and pick your agent — Claude Code, Codex, Cursor or Gemini CLI — for ready-made commands that copy the skill folder to the right place. Or copy the prompt from the “Via assistant” tab and let the assistant review and install the skill.

Which AI models work with cli-hub-matrix-3d-cad?

Skills are plain Markdown instructions (the Agent Skills format), so cli-hub-matrix-3d-cad works with any agent that reads SKILL.md: Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and more. The model loads the instructions only when a task matches the skill's description.

Is cli-hub-matrix-3d-cad free?

The skill is published openly by HKUDS under the Apache-2.0 license. The skill itself costs nothing — you only pay your AI provider for the tokens you use.

Is it safe to install skills?

A skill is a set of instructions your agent will follow, so read SKILL.md and its companion files before installing. Scripts in the skill folder only run if your agent runs them — keep an eye on what it does and do not grant unnecessary permissions.

How is a skill different from an MCP server or a plugin?

An MCP server or plugin gives the model new tools — code that runs and returns a result. A skill gives it knowledge and process: how to approach a task, which steps to follow and what good output looks like. It needs no server or API key.
