Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high System Prompt Leakage · line 215 Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. System instructions should never be exposed to end users.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00216 | $0.03302 |
| Opus 5 | $0.00108 | $0.01651 |
| Sonnet 5 | $0.00043 | $0.00660 |
| Haiku 4.5 | $0.00022 | $0.00330 |
Grade A, and why
linkfox-jiimore-page-asins-by-asin scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts

Jiimore Niche Competitor by ASIN
This skill guides you on how to query and filter Amazon competing products in the same niche segments as a reference ASIN, helping Amazon sellers discover potential competitors and evaluate opportunities using metrics such as click conversion rate, composite conversion rate, click volume, sales volume, reviews, price, FBA fees, and gross profit margin.
Core Concepts
Given a reference ASIN, the tool mines competing ASINs that share the same niche segments on Amazon and returns a paginated list with rich metrics: click conversion rate, composite conversion rate, click counts (7-day/30-day/90-day), sales volume, pricing, FBA fees, gross profit margin, customer rating, and 90-day trend data. Data is available for US, JP, and DE marketplaces only.
ASIN is required: Every query must include a reference asin. The tool finds products that share the same niche segments as this ASIN and returns them with detailed metrics.
Percentage fields: Several parameters use a 0-1 decimal range representing 0%-100%. When displaying these values to users, convert them to percentages (e.g., 0.15 -> 15%).
Date format: Launch date parameters use the format yyyyMMdd000000 (e.g., 20240101000000 for January 1, 2024).

What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
