What this skill does


# fal-train

Train custom LoRA models on fal.ai for personalized AI generation.

## Scripts

| Script | Purpose |
|--------|---------|
| `train.sh` | Submit a LoRA training job |

## Usage

### Train Image LoRA (Style/Subject/Person)
```bash
./scripts/train.sh --images-url "https://example.com/training-images.zip" --trigger-word "sks style" --model fal-ai/flux-lora-fast-training
```

### Train Portrait LoRA
```bash
./scripts/train.sh --images-url "https://example.com/face-photos.zip" --trigger-word "ohwx person" --model fal-ai/flux-lora-portrait-trainer
```

### Check Training Status
```bash
./scripts/train.sh --status --endpoint fal-ai/flux-lora-fast-training --request-id "abc123"
```

## Arguments

| Argument | Description | Required |
|----------|-------------|----------|
| `--images-url` | URL to zip of training images | Yes |
| `--trigger-word` | Word to activate the LoRA in prompts | Yes |
| `--model` / `-m` | Training model endpoint | No (default: fal-ai/flux-lora-fast-training) |
| `--steps` | Training steps | No (default: 1000) |
| `--status` | Check training job status | No |
| `--endpoint` | Endpoint for status check | With --status |
| `--request-id` | Request ID for status check | With --status |
| `--param` | Extra param as key=value (repeatable) | No |

## Finding Models

To discover the best and latest training/LoRA models, use the search API:

```bash
# Search for LoRA training models
bash /mnt/skills/user/fal-generate/scripts/search-models.sh --query "lora training"
bash /mnt/skills/user/fal-generate/scripts/search-models.sh --query "trainer"
bash /mnt/skills/user/fal-generate/scripts/search-models.sh --query "fine-tune"
```

Or use the `search_models` MCP tool with keywords like "lora", "training", "trainer", "fine-tune".

## Training Data Tips

- **People**: 10-20 photos, varied angles/lighting/expressions, consistent person
- **Styles**: 10-15 images exemplifying the style, diverse subjects
- **Objects**: 5-15 photos from different angles on various backgrounds
- Images should be high quality, at least 512x512
- Zip all images into a single .zip file and host at a URL

## Output Format
```json
{
  "diffusers_lora_file": {
    "url": "https://fal.media/files/.../lora.safetensors",
    "content_type": "application/octet-stream",
    "file_name": "lora.safetensors",
    "file_size": 12345678
  },
  "config_file": {
    "url": "https://fal.media/files/.../config.json"
  }
}
```

Use the `diffusers_lora_file.url` as the `lora_url` parameter when generating images with FLUX models.

watch

Included

Watch a video (URL or local path). Downloads with yt-dlp, extracts auto-scaled frames with ffmpeg, pulls the transcript from captions (or Whisper API fallback), and hands the result to Claude so it can answer questions about what's in the video.

physical-ai-defect-image-generation

Included

Use when the user wants to orchestrate defect image generation, run associated setup, or handle outputs on OSMO. The Day 0 path handles cold-start with USD-to-ROI, image-edit augmentation, and AnomalyGen to create initial PCBA datasets. The Day 1 path performs inference and labeling on real images. This skill helps with first-time asset setup, creation of finetuning checkpoints, and configuring deployment.

accelint-react-best-practices

Included

React performance optimization and best practices. ALWAYS use this skill when working with any React code - writing components, hooks, JSX; refactoring; optimizing re-renders, memoization, state management; reviewing for performance; fixing hydration mismatches; debugging infinite re-renders, stale closures, input focus loss, animations restarting; preventing remounting; implementing transitions, lazy initialization, effect dependencies. Even simple React tasks benefit from these patterns. Covers React 19+ (useEffectEvent, Activity, ref props). Triggers - useEffect, useState, useMemo, useCallback, memo, inline components, nested components, components inside components, re-render, performance, hydration, SSR, Next.js, useDeferredValue, combined hooks.

humanizer

Included

Humanize AI-generated text by detecting and removing patterns typical of LLM output. Rewrites text to sound natural, specific, and human. Uses 28 pattern detectors, 560+ AI vocabulary terms across 3 tiers, and statistical analysis (burstiness, type-token ratio, readability) for comprehensive detection. Use when asked to humanize text, de-AI writing, make content sound more natural/human, review writing for AI patterns, score text for AI detection, or improve AI-generated drafts. Covers content, language, style, communication, and filler categories.

generating-mermaid-diagrams

Included

Salesforce architecture diagrams using Mermaid with ASCII fallback. Use this skill when generating text-based diagrams for Salesforce architecture, OAuth flows, ERDs, integration sequences, or Agentforce structure. TRIGGER when: user says "diagram", "visualize", "ERD", or asks for sequence diagrams, flowcharts, class diagrams, or architecture visualizations in Mermaid. DO NOT TRIGGER when: user wants PNG/SVG image output (use generating-visual-diagrams), or asks about non-Salesforce systems.
