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 →

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 | $0.00152 | $0.02005 |
| Opus 5 | $0.00076 | $0.01002 |
| Sonnet 5 | $0.00030 | $0.00401 |
| Haiku 4.5 | $0.00015 | $0.00200 |
Grade A, and why
linkfox-walmart-search 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.

Walmart Product Search
This skill enables you to search and retrieve Walmart product listing data, helping e-commerce sellers and researchers extract actionable insights from Walmart's marketplace.
Core Concepts
Walmart Product Search retrieves real-time product listing data from Walmart's marketplace. It supports keyword-based search, category browsing, price filtering, sorting options, and device-specific results. This is a direct search tool that returns current product listings as they appear on Walmart.com.
Search modes: You can search by keyword, by category ID, or by combining both. At least one of keyword or categoryId must be provided.
Sorting options: Results can be sorted by best_seller, best_match, price_low (price ascending), or price_high (price descending). When no sort is specified, the default relevance-based ranking applies.
Pagination: Results are paginated with a default of page 1. The maximum page number is 100.

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.
