Security Scan

The skill performs the described graphic-trademark checks by calling an external LinkFox API, but its package metadata omits the required API credential and does not disclose transmission of images to an external service—this mismatch and the privacy implication warrant caution.

Purpose & Capability

The SKILL.md, API reference, and included script all implement a graphic-trademark detection flow that matches the skill's stated purpose (YOLO detection + similarity search against trademark DBs). However, the registry metadata lists no required environment variables or primary credential even though the code and API docs require an API key (LINKFOXAGENT_API_KEY). Omitting this required credential from metadata is an incoherence that could mislead users.

Instruction Scope

Runtime instructions and the script direct the agent to send user-supplied images (imageUrl or base64) and optional product metadata to an external endpoint (https://tool-gateway.linkfox.com/ruiguan/trademarkGraphicDetection). Sending full images and titles to a third-party service is expected for this functionality but is a privacy/data-exfiltration risk that should be explicitly declared. The instructions also reference a separate feedback endpoint (skill-api.linkfox.com). The script expects an environment variable for auth that is not declared in the skill metadata, which is a scope mismatch.

Install Mechanism

No install spec is provided (instruction-only plus a small helper script), so nothing is automatically downloaded or executed beyond the included script. This is the lower-risk option for installation mechanics.

Credentials

The skill requires an API key (LINKFOXAGENT_API_KEY) per references/api.md and the included Python script, yet the registry metadata claims no required env vars or primary credential. Requiring an API key to call an external service is reasonable for the feature, but the missing declaration is a significant inconsistency. Users should treat that key as a secret and confirm how LinkFox stores or uses submitted images and metadata.

Persistence & Privilege

The skill does not request elevated or persistent privileges: always is false, it does not modify other skills or system settings, and it does not embed persistent autorun behavior. It simply invokes an external API at runtime.

What to consider before installing

This skill appears to implement the advertised trademark-image checks, but there are two things to be careful about: (1) the skill actually requires an API key (LINKFOXAGENT_API_KEY) even though the metadata doesn’t declare it—ask the publisher to update the metadata before installing; (2) using the skill sends your product images and optional product titles to https://tool-gateway.linkfox.com and a feedback endpoint, which may expose sensitive visuals or business data. Before enabling: verify LinkFox’s privacy and retention policies, only test with non-sensitive images first, store the API key as a least-privilege credential and rotate it if needed, and request clarification from the skill owner (owner ID present) about what data is logged/stored and how long it is retained. If you cannot verify those points, avoid sending private or customer images to the service.

Ruiguan Graphic Trademark Detection

This skill guides you on how to detect graphic trademarks in product images, helping e-commerce sellers and brand owners identify potential trademark infringement risks before listing products.

Core Concepts

Graphic trademark detection analyzes a product image to find visually similar registered trademarks across multiple countries and regions. The tool uses YOLO-based object detection to locate logo-like regions in the image, then compares them against trademark databases worldwide.

Similarity score: A higher similarity value means the detected graphic is more visually similar to the registered trademark. Values closer to 1.0 indicate near-identical matches and higher infringement risk.

Trademark status meanings:

Status	Meaning
registered	Trademark is actively registered
act	Trademark is active
pend	Trademark application is pending
filed	Trademark application has been filed
ended	Trademark has expired
DEL	Trademark has been deleted/cancelled

Parameter Guide

Parameter	Required	Description	Default
imageUrl	Yes	Product image URL or base64-encoded image data	-
topNumber	Yes	Maximum number of detection results to return (1-100)	5
productTitle	No	Product title, helps improve detection accuracy	-
trademarkName	No	Suspected logo name, helps narrow down results	-
regions	No	Country/region codes to check, comma-separated. If omitted, all countries are searched	All
enableLocalizing	No	Whether to enable image cropping for detected regions	false
enableRadar	No	Whether to enable radar monitoring	true

Supported Regions

US (United States), WO (WIPO), ES (Spain), GB (United Kingdom), DE (Germany), IT (Italy), CA (Canada), MX (Mexico), EM (European Union), AU (Australia), FR (France), JP (Japan), TR (Turkey), BX (Benelux), CN (China)

When the user does not specify a region, omit the regions parameter so all countries are searched by default.

Usage Examples

1. Basic image trademark check Detect trademarks in a product image across all regions, returning up to 10 results:

imageUrl: "https://example.com/product-image.jpg"
topNumber: 10

2. Region-specific trademark check Check a product image against US and EU trademark databases only:

imageUrl: "https://example.com/product-image.jpg"
topNumber: 5
regions: "US,EM"

3. Detailed check with product context Provide product title and suspected logo name for more accurate detection:

imageUrl: "https://example.com/product-image.jpg"
topNumber: 10
productTitle: "Wireless Bluetooth Headphones with Noise Cancellation"
trademarkName: "SonicWave"
regions: "US,GB,DE"

4. Full detection with image cropping Enable localizing to get cropped images of detected logo regions:

imageUrl: "https://example.com/product-image.jpg"
topNumber: 20
enableLocalizing: true
regions: "US"

API Usage

This tool calls the LinkFox tool gateway API. See references/api.md for calling conventions, request parameters, and response structure. You can also execute scripts/ruiguan_trademark_graphic_detection.py directly to run detections.

Display Rules

1. Present results clearly: Show detection results in a well-structured table including trademark image, similarity score, trademark name, status, registration office, Nice classification, applicant name, and key dates
2. Highlight high-risk matches: When similarity is above 0.8, explicitly warn the user about high infringement risk
3. Explain trademark status: When showing results, clarify what each trademark status means for the user's risk assessment
4. Radar results: If radarResult is present in the response, display it prominently as it contains aggregated risk assessment
5. Sub-radar results: If individual items contain subRadarResult, include this information alongside each match
6. Region context: Always indicate which regions were searched so the user understands the scope of the check
7. Error handling: When a detection fails, explain the reason based on the response and suggest adjustments (e.g., using a clearer image, specifying regions, adjusting topNumber)

Important Limitations

• Image requirement: The imageUrl parameter is mandatory; the tool cannot perform detection without an image
• Result cap: The topNumber parameter caps at 100 results per request
• Image quality: Detection accuracy depends on image resolution and clarity; higher quality images yield better results
• Region coverage: Not all countries are covered; the supported list includes 15 major trademark offices

User Expression & Scenario Quick Reference

Applicable -- Graphic trademark detection tasks:

User Says	Scenario
"Check if this image has trademark issues"	Basic trademark detection
"Is this logo registered anywhere"	Multi-region trademark search
"Trademark risk for my product image"	Product listing risk assessment
"Find similar trademarks to this graphic"	Similarity search
"Check this image against US trademarks"	Region-specific detection
"Does this design infringe any trademark"	Infringement risk check
"Scan my product photo for logos"	Logo detection in product images

Not applicable -- Needs beyond graphic trademark detection:

• Text/word trademark search (no image involved)
• Trademark registration or filing
• Patent or copyright checks
• Legal advice on trademark disputes
• Product listing optimization

Boundary judgment: When users say "check my product" or "is this safe to sell", if the concern relates to graphic elements or logos in product images potentially infringing registered trademarks, this skill applies. If they are asking about text trademarks, patent issues, or general legal compliance, it does not apply.
