README (SKILL.md)
Simple Calculator
概述
极简命令行计算器，支持基本四则运算和幂运算。
核心命令
python3 scripts/calc.py "3 + 2"
python3 scripts/calc.py "10 / 4"
python3 scripts/calc.py "2 ** 10"
支持运算
| 运算 | 符号 | 示例 |
|---|---|---|
| 加 | + | 5 + 3 → 8 |
| 减 | - | 10 - 4 → 6 |
| 乘 | * | 3 * 7 → 21 |
| 除 | / | 10 / 3 → 3.3333 |
| 幂 | ** | 2 ** 8 → 256 |
| 取余 | % | 10 % 3 → 1 |
验证
python3 scripts/calc.py "1 + 1"
# 输出: 2
Usage Guidance
Safe to install for simple local calculations. Be aware it runs a local Python script and uses eval internally, so avoid feeding it extremely large expressions; a future version should preferably use an AST-based arithmetic evaluator.
Capability Assessment
Purpose & Capability
The stated purpose is simple command-line math, and the artifact contains only a short README-style skill file plus a Python calculator script.
Instruction Scope
Runtime instructions are limited to user-invoked calculator examples; there are no role changes, hidden directives, broad automation, or unrelated agent instructions.
Install Mechanism
The artifact has no package dependencies, install hooks, background workers, or registry-based dependency surface; it is just SKILL.md and scripts/calc.py.
Credentials
The script uses Python eval for arithmetic after a restrictive character allowlist and disabled builtins; this is proportionate for a toy calculator but safer AST-based evaluation would reduce residual risk from expensive expressions.
Persistence & Privilege
No persistence, privilege escalation, credential handling, profile/session access, file mutation, network access, or long-running behavior is present.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install simple-calculator - After installation, invoke the skill by name or use
/simple-calculator - Provide required inputs per the skill's parameter spec and get structured output
