## What it does

fal-train is an OpenDesign catalogue skill that points your agent at LoRA training on fal.ai. It fits projects where generated images have to look like your brand, a specific character or a repeating style rather than generic output.

The entry ships a `SKILL.md` in the nexu-io/open-design repo and links upstream to fal-ai-community/skills. The actual workflow, with its scripts and assets, lives in that upstream bundle, so you install it into your agent's skills directory as well. The agent picks fal-train up during planning and invokes it by name or through triggers such as “fal train”, “train lora” or “brand lora”.

Training on fal.ai needs an account and an API key there; without one the training step goes nowhere. If you only need prompt-to-image generation, there is nothing to train and this skill adds nothing.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add nexu-io/open-design --skill fal-train -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add nexu-io/open-design --skill fal-train -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/fal-train/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add nexu-io/open-design --skill fal-train -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/fal-train/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install nexu-io/open-design fal-train
```

2. **Manually: put the files in place**
- File: `.github/skills/fal-train/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add nexu-io/open-design --skill fal-train -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/nexu-io/open-design --path skills/fal-train
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/fal-train/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add nexu-io/open-design --skill fal-train -a opencode
```

### Claude.ai

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

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/nexu-io/open-design/tree/HEAD/skills/fal-train/SKILL.md

## When to use it
- train a LoRA on a brand's visual style
- keep one character consistent across generated images
- reproduce a single style across an image set
- wire model training into an agent inside the IDE

## Example prompts
- Train a LoRA on fal.ai from these reference images for our brand style
- Run fal-train and build a dataset for this character
- Set up custom model training for image generation

## What it does

Train custom AI models (LoRA) on fal.ai for personalized image generation tailored to a brand, character, or style.

## Source

- Upstream: https://github.com/fal-ai-community/skills
- Category: `image-generation`

## How to use

This catalogue entry advertises the skill in OpenDesign so the agent
discovers it during planning. To run the full upstream workflow with
its original assets, scripts, and references, install the upstream
bundle into your active agent's skills directory:

```bash
# Inspect the upstream README for exact paths
open https://github.com/fal-ai-community/skills
```

Then ask the agent to invoke this skill by name (`fal-train`) or with
one of the trigger phrases listed in this skill's frontmatter.
