Amazon Seller Central Guide

Amazon Seller Central listing management and optimization. Use when: user wants to create product listings, apply for GTIN exemptions, set up FBA shipments,...

Security Scan

The skill is an instruction-only Amazon Seller Central guide whose requested tools and content align with its stated purpose and does not ask for unrelated credentials, installs, or network endpoints.

Purpose & Capability

Name/description (Amazon listing, GTIN exemptions, FBA, content optimization) matches the SKILL.md and included reference docs. The metadata declares the browser tool which is appropriate for Seller Central workflows. There are no unrelated env vars, binaries, or config paths requested.

Instruction Scope

SKILL.md contains step‑by‑step, bounded guidance for listing creation, GTIN exemption, FBA shipments, images, and content. It does not instruct the agent to read arbitrary local files, exfiltrate data, or contact unexpected external endpoints. It instructs using Seller Central (via browser) which is consistent with the purpose.

Install Mechanism

No install spec and no code files to execute; instruction-only skill. package.json is metadata-only. This minimizes disk write and execution risk.

Credentials

The skill declares no required environment variables, no credentials, and no config paths. That is proportionate — Amazon account credentials would be expected for live account actions but are not requested by the skill (appropriate for a guide).

Persistence & Privilege

Skill is not always-enabled, has default invocation settings, and does not request persistent system privileges or modify other skills. Autonomous invocation is allowed by platform default but combined with the rest of the footprint this is not a new red flag.

Assessment

This skill is a text-based how-to for Amazon Seller Central and appears internally consistent. Before installing or using it: do not share your Amazon account credentials with the skill or paste them into prompts; if the agent uses a browser tool to interact with Seller Central, confirm any account actions before they are performed. For regulated categories (supplements, medical devices, electronics), verify current legal and Amazon policy requirements yourself — the guide includes disclaimers but cannot replace legal or regulatory advice. Finally, if you expect the agent to perform live uploads/edits in your Seller Central account, prefer manual approval flows and audit logs rather than giving blanket automated permission.
