Output Format
{
"sensitivity": "float",

Risk Assessment
| Risk Indicator | Assessment | Level |
|---|---|---|
| Code Execution | Python/R scripts executed locally | Medium |
| Network Access | No external API calls | Low |
| File System Access | Read input files, write output files | Medium |
| Instruction Tampering | Standard prompt guidelines | Low |
| Data Exposure | Output files saved to workspace | Low |
Security Checklist
- No hardcoded credentials or API keys
- No unauthorized file system access (../)
- Output does not expose sensitive information
- Prompt injection protections in place
- Input file paths validated (no ../ traversal)
- Output directory restricted to workspace
- Script execution in sandboxed environment
- Error messages sanitized (no stack traces exposed)
- Dependencies audited
Prerequisites
No additional Python packages required.
Evaluation Criteria
Success Metrics
- Successfully executes main functionality
- Output meets quality standards
- Handles edge cases gracefully
- Performance is acceptable
Test Cases
- Basic Functionality: Standard input → Expected output
- Edge Case: Invalid input → Graceful error handling
- Performance: Large dataset → Acceptable processing time
Lifecycle Status
- Current Stage: Draft
- Next Review Date: 2026-03-06
- Known Issues: None
- Planned Improvements:
- Performance optimization
- Additional feature support
安全使用建议
This skill appears to do what it says and uses only standard Python libraries, but review before running: (1) The script will write to whatever path you pass to --output without validating it—don’t point it at sensitive files or system paths and avoid running as a privileged user; (2) The SKILL.md mentions reading input files but the script takes CLI arguments, so confirm how you intend to supply data; (3) Test the calculations with known examples before using results clinically (NNT rounding/interpretation is simplistic); and (4) Run the script in a sandbox or isolated environment if you want extra safety. If you need automatic invocation by an agent, ensure the agent won’t supply untrusted paths for --output.
功能分析
Type: OpenClaw Skill
Name: ebm-calculator
Version: 0.1.0
The skill is a standard Evidence-Based Medicine (EBM) calculator implemented in Python. The code in scripts/main.py performs mathematical calculations for diagnostic statistics and NNT without any external network calls, obfuscation, or unauthorized system access. The SKILL.md documentation accurately describes the tool's functionality and includes a transparent risk assessment.
能力评估
Purpose & Capability
The code (scripts/main.py) implements sensitivity, specificity, PPV/NPV, likelihood ratios, NNT, and pre/post-test conversion as advertised. No unrelated binaries, credentials, or network access are requested.
Instruction Scope
SKILL.md describes file I/O and 'Read input files, write output files' in risk table, but the script accepts inputs via CLI args and only writes output if --output is provided. The documentation implies more file input behavior than the code actually performs.
Install Mechanism
Instruction-only plus one included Python script; there is no install spec, no external downloads, and no packages required beyond the standard library.
Credentials
No environment variables, credentials, or config paths are requested. The tool operates purely on provided CLI parameters.
Persistence & Privilege
Skill is not forced-always, and does not attempt to modify other skills or system-wide settings. It has normal, limited presence.
如何使用
- 确保已安装 OpenClaw（本地或 Docker 部署）
