OpenClaw 评估
The skill is internally consistent: a local Python FBA fee calculator with no external dependencies, no network access, and no credential or install requirements.
目的
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.
说明范围
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.
安装机制
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.
证书
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.
持久
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.
综合结论
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 A…

# Amazon FBA Fee Calculator — Know Your REAL Profit
**Stop guessing. Know exactly what you'll make before you sell a single unit.**
## Description
Full FBA profitability calculator with 2026 fee schedule. Calculates referral fees, FBA fulfillment fees, storage costs, and net margin. Supports all size tiers and 20+ categories.
## When to Use
- User wants to calculate Amazon FBA profitability
- 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
## Usage
```bash
# Basic: selling price + product cost
cd <skill_dir>/scripts && python3 calculator.py 24.99 5.00
# Full options
cd <skill_dir>/scripts && python3 calculator.py 9.95 2.00 --ship 0.50 --weight 8 --category grocery --units 200 --ppc 1.50
```
## Options
- `--ship COST` — Shipping cost to FBA per unit
- `--weight OZ` — Product weight in ounces
- `--dims L W H` — Dimensions in inches
- `--category CAT` — Product category (grocery, beauty, electronics, etc.)
- `--units N` — Monthly units sold (for projections)
- `--ppc COST` — PPC/advertising cost per unit
## What It Calculates
- Referral fee (category-specific, with thresholds)
- FBA fulfillment fee (weight-based, by size tier)
- Monthly storage fee (per unit, seasonal rates)
- Total cost per unit
- Profit per unit, margin %, ROI %
- Monthly and annual profit projections
- Break-even selling price
## No Dependencies
Pure Python 3. No pip install. No API keys. Works everywhere.
