Security Scan

The skill's behavior matches its stated purpose, but the package metadata omits a required credential (LINKFOXAGENT_API_KEY) and documentation points to external LinkFox endpoints with no homepage or owner verification—this mismatch and lack of provenance is concerning.

Purpose & Capability

The SKILL.md, reference doc, and included script all implement a single purpose: query Jiimore niche data from https://tool-gateway.linkfox.com/jiimore/getNicheInfo by nicheId. The code and docs are consistent with the stated capability (market insights for a single niche).

Instruction Scope

Runtime instructions and the script scope are narrow: accept a nicheId and optional countryCode, validate parameters, and POST to the documented Jiimore endpoint. The skill does not instruct reading unrelated files, scanning the system, or exfiltrating environment beyond the API key required for the service.

Install Mechanism

There is no install spec (instruction-only style) and the single Python script uses only standard libraries. No downloads or archive extraction are performed. This is low install risk.

Credentials

The code and API reference require an API key via environment variable LINKFOXAGENT_API_KEY, but the skill registry metadata declares no required environment variables or primary credential. That omission is an incoherence: the skill will not function without a secret, and the registry does not disclose or request it. Additionally, the required API key is a credential (Authorization header) and users should expect it to be declared explicitly.

Persistence & Privilege

The skill does not request always:on, does not modify other skills or system settings, and has no install steps that persist binaries. It runs a simple POST and prints results—no elevated persistence or privilege is requested.

What to consider before installing

This skill largely does what it claims (query Jiimore niche data), but note two issues before installing or using it: 1) Missing declared credential: The script and API docs require an API key in the environment variable LINKFOXAGENT_API_KEY, but the skill metadata does not list any required env vars. Ask the publisher or registry to update the skill metadata to explicitly declare this required API key (and any scopes/expiration). 2) Verify provenance before providing credentials: The skill points at tool-gateway.linkfox.com and a Feishu wiki for obtaining a key, but the package has no homepage and the publisher identity is only a registry owner ID. Confirm that LinkFox is a trusted provider for you and that the API key you obtain is intended for this use. Do not reuse high-privilege or long-lived credentials; prefer a scoped, revocable API key. 3) Operational check: If you proceed, test the skill in a controlled environment using a limited-scope or test key. Review network logs to confirm requests go only to the documented endpoints (tool-gateway.linkfox.com and the separate feedback endpoint) and that the skill does not transmit your system data. If the registry owner or homepage cannot be verified, treat the credential requirement as a red flag and avoid provisioning sensitive keys.

Jiimore Niche Market Info

This skill guides you on how to query and analyze Amazon niche market data via the Jiimore data service, helping Amazon sellers gain deep insights into specific niche markets including competition, pricing, reviews, and growth trends.

Core Concepts

A niche market in Jiimore represents a fine-grained product segment on Amazon. Each niche is identified by a unique nicheId. This tool retrieves comprehensive market intelligence for a single niche at a time, covering:

• Market overview: niche title, demand score, product count, brand count, selling partner count
• Pricing: average price, minimum price, maximum price
• Search & conversion: weekly/quarterly search volume, search volume growth, search conversion rate, click-to-sale conversion rate, units sold
• Competition concentration: top 5 / top 20 product and brand click share (current, 90-day, 360-day snapshots)
• Product launches: new products launched, successful launches across 90-day / 180-day / 360-day windows
• Inventory health: average out-of-stock rate over time
• Seller maturity: average brand age, average selling partner age
• Review insights: average review rating, average review count, positive and negative customer review insights
• Advertising: ACOS (advertising cost of sales), sponsored products percentage
• Profitability: profit margin > 50% SKU ratio, break-even ratio, return rate

Supported marketplaces: US (United States), JP (Japan), DE (Germany). Default is US.

Parameter Guide

Parameter	Type	Required	Description
nicheId	string	Yes	The niche market ID to query. Maximum 1000 characters. Only one ID per request.
countryCode	string	No	Marketplace code. Allowed values: US, JP, DE. Defaults to US.

How to Use Parameters

1. nicheId is mandatory: The user must provide or you must identify the niche market ID. This is a string identifier for a specific Amazon niche segment.
2. countryCode defaults to US: Only specify a different value when the user explicitly mentions Japan (JP) or Germany (DE).
3. Single ID per call: This tool only supports one niche ID per request. If the user wants to compare multiple niches, make separate calls.

Usage Examples

1. Basic niche market lookup (US) Query niche market data for a given niche ID in the US marketplace:

nicheId: "12345678"
countryCode: "US"

2. Query a niche in the Japan marketplace

nicheId: "87654321"
countryCode: "JP"

3. Query a niche in the Germany marketplace

nicheId: "11223344"
countryCode: "DE"

Display Rules

1. Present data clearly: Show query results in well-structured tables or grouped sections without subjective business advice unless specifically requested.
2. Trend comparison: When the response includes current, 90-day-ago, and 360-day-ago data points, present them side-by-side so users can easily spot trends.
3. Percentage formatting: Display share and rate values as percentages (e.g., 0.35 as 35.0%).
4. Review insights: If positive/negative customer review insights are present, list them as bullet points.
5. Image display: If referenceAsinImageUrl is present, display or link to the niche reference image.
6. Error handling: When a query fails, explain the reason based on the response and suggest checking the niche ID or country code.

Important Limitations

• Single ID only: Only one niche ID can be queried per request. Batch queries are not supported.
• Three marketplaces: Only US, JP, and DE are supported.
• Niche ID required: The user must supply the niche ID; this tool cannot search for niches by keyword or category.
