## What it does

You hand the skill a product list with image URLs plus a plain-language instruction about what to pull out. The model walks the list, reads each image, and appends `attributeName` and `attributeValue` to every record. Ask for two dimensions at once and the rows multiply: one row per product per attribute.

The work happens in `scripts/multimodal_extract_attributes.py`, which calls `POST /multimodal/extractPromptsFromMainImage`. The full response always lands in `<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/`; stdout gets the whole JSON, or a short summary when the body exceeds 8 KB. Writing to `/tmp` is blocked, so a read-only working directory makes the script fail outright.

Set `LINKFOX_AGENT_API_KEY` or `LINKFOXAGENT_API_KEY` before the first call. Missing keys, a 401 or a 402 send you to `references/onboarding.md` to sort out access. Watch the spend: the same parameter combination runs once per session, the script keeps a 24h local cache, and retrying with different keywords burns tokens — explain that to the user before you try again.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add linkfox-ai/linkfox-skills --skill linkfox-multimodal-extract-attributes -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add linkfox-ai/linkfox-skills --skill linkfox-multimodal-extract-attributes -a codex
```

2. **Manually: put the files in place**

## When to use it
- pull the dominant color out of a product image
- identify the material and write it into a field
- sort products by style: minimalist, vintage, bohemian
- group listings by pendant or charm shape
- reconstruct a prompt that could regenerate a similar image

## Example prompts
- Analyze each product's main image and extract the primary color
- Identify the apparent material from each main image: plastic, metal, wood, fabric
- From each main image, extract both the dominant color and the overall shape

# Product Main Image Prompt Extractor

This skill guides you on how to extract visual features and prompts from product main images using multimodal AI, helping e-commerce sellers turn unstructured image data into structured, actionable insights.

## Core Concepts

This tool performs deep visual analysis on product main images (and optionally additional images) from a product list. It uses a multimodal AI model to identify specific visual dimensions based on a natural language instruction, such as color, shape, style, material, or specific selling-point elements.

**How it works**: You provide a list of products (with image URLs) and a natural language prompt describing what to extract. The tool automatically iterates over all products, analyzes each image, and returns structured attribute data (`attributeName` + `attributeValue`) appended to each product record.

**Row expansion**: When extracting multiple dimensions in a single request (e.g., both color and shape), each original product row is duplicated per dimension, resulting in one row per product per attribute.

## Parameter Guide

| Parameter | Required | Description |
|-----------|----------|-------------|
| productImageAnalysisPrompt | Yes | Natural language instruction describing what visual information to extract from the images. Be specific about the dimensions you want (color, material, shape, style, pendant type, etc.). |
| analyzeAdditionalImages | No | Whether to also analyze additional product images beyond the main image. Defaults to `false`. |
```
