## What it does

Modly is an open-source desktop app for Windows and Linux. Feed it an image and it produces a 3D mesh, running the model entirely on your GPU. The skill covers setup, the dev build and the extension system.

Under the hood it's an Electron and TypeScript shell over a local Python FastAPI backend. Generation lives in each extension's `generator.py`, while `manifest.json` describes the model variants. Extensions install straight from a GitHub repo. For a quick start there's `launcher.bat` on Windows and `launcher.sh` on Linux; the dev path needs `npm install`, a Python virtual environment, `pip install -r requirements.txt` and then `npm run dev`.

Your GPU is the real gate here. Each variant in the manifest carries a `vram_gb` figure, and a card below it won't finish the job. Check that number before pulling weights that run several gigabytes — otherwise you wait through a download for nothing.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add reason-machines/trending-skills --skill modly-image-to-3d -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/modly-image-to-3d/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/modly-image-to-3d/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add reason-machines/trending-skills --skill modly-image-to-3d -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/modly-image-to-3d/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add reason-machines/trending-skills --skill modly-image-to-3d -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/modly-image-to-3d/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install reason-machines/trending-skills modly-image-to-3d
```

2. **Manually: put the files in place**
- File: `.github/skills/modly-image-to-3d/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add reason-machines/trending-skills --skill modly-image-to-3d -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/reason-machines/trending-skills --path skills/modly-image-to-3d
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/modly-image-to-3d/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add reason-machines/trending-skills --skill modly-image-to-3d -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- turn a single photo into a 3D mesh
- run 3D generation on your own GPU without a cloud service
- install a Modly extension from a GitHub repo
- pick a model variant that fits your VRAM
- start the local FastAPI backend for generation

## Example prompts
- install the modly-image-to-3d skill and show me how to launch Modly
- how do I install a Modly extension from GitHub and download a model variant
- check whether my VRAM is enough for the variant in manifest.json
