使用说明 (SKILL.md)
Food Expiration Calculator
This skill calculates whether a food product has expired based on the product date and shelf life.
Usage
User provides:
- Product date: The production date, manufacture date, or purchase date (format: YYYY-MM-DD)
- Shelf life: How long the product lasts (e.g., "6 months", "2 years", "18 months")
Output
The calculator returns:
- Expiration date
- Days remaining until expiration (or days since expiration)
- Status: "Fresh" (more than 30 days left), "Expiring Soon" (less than 30 days), or "Expired"
Script
Use the Python script scripts/food_expiry.py to calculate:
python scripts/food_expiry.py --date 2025-06-01 --shelf-life "6 months"
Arguments:
--dateor-d: Product date (YYYY-MM-DD)--shelf-lifeor-s: Shelf life (e.g., "6 months", "2 years", "18 days")
The script outputs the expiration date, days remaining, and status.
安全使用建议
This skill appears safe: it contains a small Python script that parses dates and prints an expiration status, with no network activity or secret access. If you rely on exact calendar math, note the script approximates months as 30 days and years as 365 days. You can review the included scripts locally before running; run them in your normal environment (python3) — no external keys or installs are required.
功能分析
Type: OpenClaw Skill
Name: food-cal
Version: 1.0.0
The skill bundle is a straightforward utility for calculating food expiration dates. The Python script `scripts/food_expiry.py` uses standard libraries to process date strings and shelf-life durations without any network access, file system manipulation, or sensitive data retrieval. No malicious instructions or suspicious patterns were identified in the code or documentation.
能力评估
Purpose & Capability
The script and SKILL.md implement a simple expiration-date calculator matching the name/description. No unrelated binaries, credentials, or config paths are requested.
Instruction Scope
SKILL.md only instructs running the included Python script with a product date and shelf-life string. The script only parses inputs, does date math, and prints results; it does not read other files, environment variables, or contact external endpoints.
Install Mechanism
No install spec is provided (instruction-only with a bundled script). This minimizes installation risk — nothing is downloaded or written to disk beyond the provided file.
Credentials
The skill requires no environment variables, credentials, or external configuration. The declared requirements match the implementation.
Persistence & Privilege
The skill does not request permanent presence (always:false) and does not modify system or other skills' configuration. Autonomous invocation is allowed by default but is not combined with any broad privileges.
如何使用
- 确保已安装 OpenClaw（本地或 Docker 部署）
- 在对话框中输入安装命令：
/install food-cal - 安装完成后，直接呼叫该 Skill 的名称或使用
/food-cal触发 - 根据 Skill 的参数说明提供必要输入，即可获得结构化输出
