This skill guides you on how to query and analyze Amazon niche market review data powered by Jiimore, helping Amazon sellers uncover consumer sentiment, pain points, and real demand signals from product reviews within niche markets.
Core Concepts
Niche Review Analysis aggregates and categorizes customer reviews across products in an Amazon niche market. Given a keyword, the system identifies the relevant niche markets, extracts review topics, classifies them as positive or negative, and shows how frequently each topic is mentioned. This enables sellers to understand what customers love, what frustrates them, and where product improvement opportunities exist.
Review types: Each review entry is classified as either "positive" or "negative", reflecting the overall sentiment of that review topic.
Mention percentage: The percentOfMentions value (0-1 scale, representing 0%-100%) indicates how frequently a particular topic appears across all reviews in the niche. A higher percentage means more customers are talking about that topic.
Supported Marketplaces
US (United States), JP (Japan), DE (Germany)
Default marketplace is US. Use US when the user does not specify a marketplace.
How to call
- API endpoint：
POST /jiimore/getNicheReviewFromKeyword(for full parameters/responses/error codes, seereferences/api.md） - Python script：
python scripts/jiimore_get_niche_review.py '<JSON 参数>' [--inline] - Cost constraints: This tool consumes compute; by default, the same parameter combination is called only once per session, and the script has a 24h local cache. On failure/empty results, do not automatically switch keywords, paginate, or change the zip code to probe repeatedly; if further retrieval is needed, first explain to the user that it will incur additional consumption.
Output strategy (default script behavior)：
- Alwayswrite the full response to
<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-jiimore-get-niche-review-from-keyword-<timestamp>.json（<cwd>is the working directory when the script runs, which in Claude Code is the current project directory;<session>is taken from the environment variableSESSION_ID, automatically aggregated according to the user's task;writing to /tmp is prohibited, and if the current directory is not writable, report an error) - Response body ≤ 8 KB: after writing to disk, print the full JSON to stdout
- Response body > 8 KB: after writing to disk, stdout outputs only a summary (top-level fields, common counts such as
total/costToken, the length of the largest list field + the first 3 samples) - Add
--inlineto force full printing to stdout (also written to disk)
Data reading suggestions: first look at the summary to judge whether it is sufficient; when specific fields are needed, prefer to use jqorConvertFrom-Json to extract on demand from the saved json file, avoiding bringing the entire JSON into context.
Resolve authentication and compute issues
When the following abnormal situations occur, use references/onboarding.md to guide resolution:
Abnormal situations
- API Key not configured: the environment variable is not configured
LINKFOX_AGENT_API_KEY, andLINKFOXAGENT_API_KEY。 - Response 401 or 402 status code
- Response indicates insufficient compute or balance: the message contains "insufficient compute balance/insufficient billing/insufficient balance/quota exceeded/insufficient balance/package expired/recharge required/please recharge", or content with a similar meaning.

- Percentage formatting: Convert 0-1 scale values to percentages for display (e.g., 0.15 -> 15%)
- Sentiment separation: When presenting results, group or clearly label positive vs. negative reviews so users can quickly identify opportunities and pain points
- Actionable insight framing: While showing data objectively, highlight high-mention-percentage negative reviews as potential product improvement opportunities, and high-mention-percentage positive reviews as features to emphasize in listings
- Volume notice: When results are large, show the most relevant data first and remind users about pagination options
- Error handling: When a query fails, explain the reason and suggest adjusting the keyword or filter criteria
- Language reminder: If a user provides a keyword in the wrong language for the target marketplace, remind them to use the marketplace's native language (English for US, German for DE, Japanese for JP)
User Expression & Scenario Quick Reference
Applicable -- Consumer review and sentiment analysis within Amazon niche markets:
| User Says | Scenario |
|---|---|
| "What do customers say about XX" | Niche review topic lookup |
| "Customer pain points for XX" | Negative review analysis |
| "What features do buyers love in XX" | Positive review analysis |
| "Review sentiment for XX niche" | Full sentiment breakdown |
| "Consumer demand insights for XX" | Demand signal extraction from reviews |
| "Common complaints about XX products" | Negative topic mining |
| "What makes XX products popular" | Positive topic mining |

Not applicable -- Needs beyond niche review analysis:
- Individual ASIN review analysis (this tool works at the niche/market level)
- Keyword search volume trends without review context (use ABA data tools instead)
- Product listing optimization or copywriting
- Advertising strategy and PPC management
- Sales estimation or revenue forecasting
Boundary judgment: When users say "market research" or "product opportunity", if their intent focuses on understanding consumer sentiment, review topics, and pain points within a niche market, this skill applies. If they are asking about search volume trends, pricing strategy, or sales data without review context, it does not apply.
