使用说明 (SKILL.md)
Calculator Skill
A simple calculator skill that performs basic arithmetic operations.
When This Skill Applies
This skill activates when the user's request involves:
- Basic arithmetic calculations (addition, subtraction, multiplication, division)
- Math expressions evaluation
- Number computation requests
Instructions
When this skill is activated:
- Parse the mathematical expression from the user's request
- Perform the calculation step by step
- Return the result clearly
Supported Operations
| Operation | Symbol | Example | Result |
|---|---|---|---|
| Addition | + | 1 + 1 | 2 |
| Subtraction | - | 10 - 3 | 7 |
| Multiplication | * | 4 * 5 | 20 |
| Division | / | 20 / 4 | 5 |
Example
User: What is 1 + 1?
Steps:
- Parse expression:
1 + 1 - Perform addition:
1 + 1 = 2 - Return result: 2
Rules
- Always show the calculation process
- For division, check for division by zero and warn the user
- Support chained operations (e.g.,
1 + 2 * 3) - Follow standard mathematical order of operations (PEMDAS)
- Return results with appropriate precision (avoid unnecessary decimal places)
安全使用建议
This skill appears benign and self-contained for basic arithmetic. Before installing, consider whether you or the implementer might later add code that evaluates user input with an unsafe mechanism (for example, using a raw eval on arbitrary strings). If you plan to rely on this for more than simple math, confirm the implementation sanitizes/parses expressions safely and does not execute arbitrary code or access external resources.
功能分析
Type: OpenClaw Skill
Name: calculator-2
Version: 0.1.0
The skill bundle contains standard metadata and documentation for a basic calculator. The instructions in SKILL.md are limited to performing arithmetic operations and do not contain any malicious directives, prompt injection attempts, or suspicious network/file system requests.
能力评估
Purpose & Capability
Name/description match the declared behavior: only basic arithmetic and expression evaluation. No unrelated env vars, binaries, or config paths are requested.
Instruction Scope
SKILL.md instructions are narrowly scoped to parsing expressions, performing step-by-step calculations, and returning results; it does not instruct the agent to read files, access external endpoints, or collect unrelated data.
Install Mechanism
No install spec or code files are present (instruction-only), so nothing is written to disk or downloaded during install.
Credentials
No environment variables, credentials, or config paths are required; requested access is proportionate to a calculator's needs.
Persistence & Privilege
Skill does not request always:true or other elevated persistence; normal autonomous invocation is allowed by platform defaults.
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 calculator-2 - 安装完成后，直接呼叫该 Skill 的名称或使用
/calculator-2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
