Description
Calculate Body Mass Index (BMI) with health category assessment. Supports metric and imperial units. Pure Python standard library, no API key required.
README (SKILL.md)
BMI Calculator
Calculate your Body Mass Index (BMI) and get health category assessment.
Features
- Calculate BMI from height and weight
- Support metric (cm/kg) and imperial (ft-in/lbs) units
- Health category classification (Underweight, Normal, Overweight, Obese)
- Healthy weight range calculation
- Pure Python, no external dependencies
Usage
python3 scripts/bmi_calculator.py --height 175 --weight 70
python3 scripts/bmi_calculator.py --height 5ft9in --weight 154lbs
Output
Returns BMI value, health category, and healthy weight range.
Usage Guidance
This skill looks safe for normal use as a local BMI calculator. Height and weight are personal information, so only enter values you are comfortable processing locally, and do not provide any API keys, passwords, or account credentials because the reviewed artifacts do not require them.
Capability Analysis
Type: OpenClaw Skill
Name: cn-bmi-calculator
Version: 1.0.0
The skill bundle is a straightforward BMI calculator that uses only Python standard libraries. Analysis of scripts/bmi_calculator.py shows safe handling of user input via argparse and regex for unit conversion, with no evidence of network access, file system manipulation, or malicious intent. The SKILL.md documentation accurately describes the tool's functionality and contains no prompt injection attempts.
Capability Tags
Capability Assessment
Purpose & Capability
The stated purpose is BMI calculation, and the included Python script only parses height and weight, computes BMI/category, and prints JSON output.
Instruction Scope
The skill provides straightforward user-directed command examples and does not include agent-goal overrides, hidden instructions, or autonomous high-impact workflows.
Install Mechanism
There is no install spec and no external dependency installation; the included script uses only Python standard-library modules.
Credentials
The capability signal says sensitive credentials are required, which is inconsistent with the registry requirements, SKILL.md, and code showing no credential use.
Persistence & Privilege
The artifacts show no persistence, privilege escalation, background activity, network access, file writes, or credential/session handling.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install cn-bmi-calculator - After installation, invoke the skill by name or use
/cn-bmi-calculator - Provide required inputs per the skill's parameter spec and get structured output
