nexscope-ai 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
| Parameter | Type | Required | Description | Example |
|---|---|---|---|---|
| Image URL | imageUrl | Yes | The URL of the product image to check (max 1000 chars) | https://example.com/product.jpg |
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
| Field | API Name | Description |
|---|---|---|
| Total Matches | total | Number of matching violation records found |
| Violation List | data | Array of matched violating products |
| Violation Image | pdImgOssUrl | Image URL of the matched violating product |
| Similarity Score | cosine | Similarity between the input image and the violation (0~1) |
| Product Title (EN) | pdTitle | English title of the matched violating product |
| Product Title (CN) | pdTitleCHNCensored | Chinese title of the matched violating product |
| Detection ID | detectId | Unique identifier for this detection session |
| Token Cost | costToken | Number of tokens consumed by this request |
Usage
- API Endpoint:
POST /ruiguan/gunPartsSearch(seereferences/api.mdfor full parameters, responses, and error codes) - Python Script:
python scripts/ruiguan_image_compliance_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
- Show results in a clear table: Present each matched violation with its image, similarity score, and product titles
- Highlight high-similarity matches: When the cosine score exceeds 0.8, clearly flag the result as a strong match that likely requires attention
- Include violation images: When results contain
pdImgOssUrl, display the matched violation image so the user can visually compare - Score interpretation: Always explain what the similarity score means -- higher values indicate closer resemblance to known violations
- Error handling: When a query fails, explain the issue and suggest checking whether the image URL is valid and publicly accessible
- 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:
| User Says | Scenario |
|---|---|
| "Check if this product image has compliance risks" | Single image compliance check |
| "Scan my product images for policy violations" | Batch compliance screening |
| "Is this image flagged as a prohibited product" | Specific violation inquiry |
| "Pre-screen my listing images for policy risks" | Pre-listing compliance audit |
| "Find similar violations for this product image" | Similarity-based violation search |
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)
