Jiimore Niche Review from Keyword

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 Invoke

• API Endpoint: POST /jiimore/getNicheReviewFromKeyword (complete params/response/error codes in references/api.md)
• Python Script: python scripts/amazonnichereviewsbykeyword.py '<JSON params>' [--inline]
• Cost constraint: This tool consumes credits; the same session and parameter combination is called only once by default, with a 24h local cache in the script. On failure or empty results, do not automatically retry with different keywords, pagination, or postal codes; inform the user about additional consumption before continuing to search.

Output strategy (script default behavior):

• Always write the full response to <cwd>/nexscope/<YYYY-MM-DD>/<session>/data/nexscope-jiimore-get-niche-review-from-keyword-<timestamp>.json (<cwd> is the working directory at script execution time, i.e. the current project directory in Claude Code; <session> is taken from the SESSION_ID env var, auto-grouped by user task; do not write to /tmp, error if current directory is not writable)
• Response body <= 8 KB: print full JSON to stdout after saving
• Response body > 8 KB: print only summary to stdout after saving (top-level fields, common counts like total/costToken, length of largest list field + first 3 samples)
• Add --inline to force full output to stdout (still saves to disk)

Data reading tip: Check the summary first to decide if it's enough; when specific fields are needed, prefer using jq or ConvertFrom-Json to extract from the saved json file on demand, avoiding loading the entire JSON into context.

Display Rules

1. Present data clearly: Show review topics in a well-organized table. Include the niche name, review type (positive/negative), topic, mention percentage, and a review example
2. Percentage formatting: Convert 0-1 scale values to percentages for display (e.g., 0.15 -> 15%)
3. Sentiment separation: When presenting results, group or clearly label positive vs. negative reviews so users can quickly identify opportunities and pain points
4. 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
5. Volume notice: When results are large, show the most relevant data first and remind users about pagination options
6. Error handling: When a query fails, explain the reason and suggest adjusting the keyword or filter criteria
7. 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:

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.
