User asks about Amazon fees, margins, or ROI
User is evaluating whether to sell a product on Amazon
User compares FBA vs FBM costs
User mentions COGS, margin, or break-even price

安全使用建议

This skill appears to be a straightforward, local Python calculator. It does not request credentials or network access and prints results to stdout. Before installing/using: (1) inspect the included scripts (already provided) to confirm they match your expectations — the code here is visible and benign; (2) run it locally in a controlled environment (Python 3) if you want to verify outputs; (3) verify the fee schedule values against official Amazon documentation if you need regulatory/financial accuracy; and (4) be cautious installing packages from unknown authors in other cases — here the absence of downloads, env vars, and network calls reduces risk.

功能分析

Type: OpenClaw Skill Name: amazon-fee-calculator Version: 1.0.0 The skill bundle is a legitimate Amazon FBA profitability calculator. The Python script (scripts/calculator.py) performs mathematical calculations based on hardcoded 2026 fee schedules and does not contain any network requests, file system modifications, or suspicious execution patterns. The instructions in SKILL.md are consistent with the tool's purpose and do not attempt to manipulate the AI agent into performing unauthorized actions.

能力评估

✓ Purpose & Capability

Name/description match the included assets: SKILL.md documents running scripts/calculator.py and the script implements referral, fulfillment, and storage fee calculations for FBA. No unrelated credentials, binaries, or services are requested.

✓ Instruction Scope

Runtime instructions merely run the bundled Python script from the scripts directory with CLI options. The SKILL.md does not instruct the agent to read unrelated files, contact external endpoints, or exfiltrate data.

✓ Install Mechanism

No install spec is provided (instruction-only plus a local script). Nothing is downloaded or written to disk beyond the included files, so there is no high-risk install step.

✓ Credentials

The skill declares no required environment variables, credentials, or config paths. The script uses only standard-library modules and command-line arguments; no secrets are requested or accessed.

✓ Persistence & Privilege

The skill does not request always:true or modify other skills or system configuration. It runs only when invoked by the user (user-invocable) and does not autonomously reach out to external services.
