Policy Compliance Image Detection

This skill guides you on how to use the policy compliance detection tool to identify potential policy violations in product images. It performs image-based similarity search against a known database of prohibited products.

Core Concepts

Policy Compliance Image Detection is an image-based compliance screening service. Given a product image URL, it searches for visually similar products in a database of known policy-violating items. The tool returns matching violations ranked by visual similarity.

Similarity score (cosine): A value between 0 and 1. Higher values indicate stronger visual resemblance to known violating products. A score close to 1.0 means the product image is nearly identical to a flagged violation.

Parameter Guide

Key notes:

• The image URL must be publicly accessible
• Supported formats include common image types (JPG, PNG, etc.)
• The URL must not exceed 1000 characters

Response Fields

Usage

• API Endpoint: POST /ruiguan/gunPartsSearch (see references/api.md for full parameters, responses, and error codes)
• Python Script: python scripts/ruiguanimagecompliance_search.py '<JSON parameters>'

Output strategy (script default behavior):

• Prints the full JSON response to stdout

Data reading tip: Use jq or ConvertFrom-Json to extract specific fields from the response as needed.

Usage Examples

1. Basic compliance check for a single product image

Check this product image for policy compliance: https://example.com/images/product-123.jpg

2. Batch checking multiple product images

Please scan these product images for potential policy violations:
- https://example.com/images/item-a.jpg
- https://example.com/images/item-b.jpg

3. Pre-listing compliance screening

Before I list this product, can you check if the image triggers any policy flags?
Image: https://example.com/new-product.png

Display Rules

1. Show results in a clear table: Present each matched violation with its image, similarity score, and product titles
2. Highlight high-similarity matches: When the cosine score exceeds 0.8, clearly flag the result as a strong match that likely requires attention
3. Include violation images: When results contain pdImgOssUrl, display the matched violation image so the user can visually compare
4. Score interpretation: Always explain what the similarity score means -- higher values indicate closer resemblance to known violations
5. Error handling: When a query fails, explain the issue and suggest checking whether the image URL is valid and publicly accessible
6. No legal advice: Present detection results factually without providing legal conclusions; remind users to verify with platform policies

Important Limitations

• Image-only detection: This tool works exclusively with image URLs; it does not analyze text descriptions or product metadata
• URL accessibility: The image URL must be publicly reachable by the detection service
• URL length cap: Image URLs must not exceed 1000 characters
• Similarity-based: Results are based on visual similarity and do not constitute a definitive policy ruling

User Expression & Scenario Quick Reference

Applicable -- Image-based product policy compliance checks:

Not applicable -- Needs beyond image-based policy compliance detection:

• Text-based product compliance analysis
• General product category classification
• Intellectual property / trademark infringement
• Patent or copyright detection (use other detection skills)
