Supply Chain Bottleneck Analyzer for Walmart Marketplace sellers. Diagnose cash flow, inventory, WFS costs, and referral fees. Includes comparison with Amazo...

Security Scan

The skill appears to do what it claims — a local supply-chain calculator for Walmart sellers with optional API integration — and its requirements and implementation are proportionate to its stated purpose.

Purpose & Capability

Name/description (Walmart supply-chain analyzer) align with the included calculator code and SKILL.md. The package also contains cross-platform benchmarks (Amazon, TikTok, Shopify) used for comparison — this is reasonable for a comparative tool but slightly broader than the Walmart-only phrasing. Minor mismatch: internal code uses Amazon-oriented names (fba_fee) and a hard-coded 14-day payment term comment for the cash-cycle calculation which may not reflect Walmart's 14–21 day cycle.

Instruction Scope

SKILL.md describes a 4-step flow and shows example exports for WALMART_CLIENT_ID and WALMART_CLIENT_SECRET for optional API integration; otherwise it instructs the agent to collect seller-provided numeric inputs. It does not instruct reading unrelated system files or exfiltrating data. The agent could be configured to call Walmart APIs if the user supplies credentials, which matches the documented optional integration.

Install Mechanism

This is instruction-only (no install spec in the registry). SKILL.md shows an npx command to add the skill (which would download a package if used) but the registry bundle already contains a local calculator.py. No downloads, external URLs, or archive extracts are present in the skill bundle itself.

Credentials

The skill declares no required environment variables in metadata. SKILL.md includes example WALMART_CLIENT_ID/WALMART_CLIENT_SECRET exports for optional API integration — this is proportionate to a marketplace integration but the credentials are optional; nothing else requests unrelated secrets.

Persistence & Privilege

Skill does not request always:true, does not modify other skills or system configs, and requires no elevated privileges. It is user-invocable and can be invoked autonomously per platform defaults (normal for skills).

Assessment

This skill is internally consistent and appears to be a local calculator plus optional Walmart API integration. Before installing or supplying credentials: (1) only provide WALMART_CLIENT_ID/SECRET if you intend to enable API data pulls; otherwise use manual inputs. (2) Review or run the calculator.py locally on non-sensitive test data first — the code is straightforward but assumes a non-zero selling price (watch for division-by-zero). (3) Note minor inconsistencies (some Amazon-named variables and a hard-coded 14-day payment term in code) — verify the cash-cycle logic matches your Walmart payment timing. (4) If you plan to run the npx install command shown in SKILL.md, remember that npx will fetch a package from the npm registry — confirm the npm package and publisher are trustworthy before executing.
