Security Scan

The skill's code, instructions, and declared requirements are consistent with an Amazon FBA profit-margin calculator and do not request unrelated credentials or install arbitrary remote code.

Purpose & Capability

Name/description match the included Python script and SKILL.md: both implement cost breakdowns, margin and break-even calculations, and batch/CSV input support. No unrelated capabilities (cloud access, secret retrieval, or system-level changes) are requested.

Instruction Scope

Runtime instructions are focused on providing product inputs and running the local script (python3 scripts/calculator.py). The SKILL.md does not instruct the agent to read unrelated system files, environment variables, or to exfiltrate data. It does include an example npx install command for adding the skill via an external package manager, but that is an installation convenience rather than a runtime requirement.

Install Mechanism

No formal install spec in registry metadata (instruction-only install). SKILL.md suggests using 'npx skills add nexscope-ai/eCommerce-Skills ...' which would fetch an external package — verify you trust that package/source before running npx, but the shipped files include the calculator.py so no remote fetch is strictly required to run the calculator locally.

Credentials

The skill declares no required environment variables, primary credentials, or config paths. The code uses only standard Python libraries and user-provided input (JSON/CSV), which is proportionate for the stated purpose.

Persistence & Privilege

The skill is not always-enabled and does not request persistence or elevated privileges. It does not modify other skills or system-level settings based on available information.

Assessment

This skill appears to do what it says: a local Python calculator that takes product inputs and returns margin/break-even analyses. Before installing or running: (1) inspect the full scripts/calculator.py file (the provided snippet is truncated) to ensure no unexpected network calls or file I/O; (2) be cautious about running the SKILL.md's npx command — that will fetch code from an external package (verify the package/owner); (3) run the script in a controlled environment (virtualenv/container) if you want to avoid risk from executing unreviewed code; and (4) be aware of minor coding issues (e.g., potential enum/name mismatches in the truncated code) that could cause runtime errors — these are quality issues, not indicators of malicious behavior.

Calculate product profitability for Amazon FBA sellers — cost breakdowns, profit margins, break-even analysis, and pricing recommendations. No API key required.

Handling Incomplete Input

If user doesn't provide enough info, ask:

To calculate your profit margin, I need:

**Required:**
- Selling price
- Product cost (FOB)
- FBA fulfillment fee

**Recommended (more accurate):**
- Inbound shipping cost per unit
- FBA storage fee per unit/month
- Ad spend ratio (% of sales)
- Product category (for referral fee)
