Usage Guidance

This skill looks safe for local tip calculations. Before installing, note that the registry capability signal about sensitive credentials appears inconsistent with the actual artifacts; do not provide any credentials if prompted by anything outside these reviewed files.

Capability Analysis

Type: OpenClaw Skill Name: cn-tip-calculator Version: 1.0.0 The skill is a straightforward tip calculator that uses the Python standard library to perform basic arithmetic. The script 'scripts/tip_calculator.py' contains no network, file system, or environment access, and the documentation in 'SKILL.md' is consistent with the code's functionality without any signs of prompt injection or malicious intent.

The stated purpose is calculating tips and splitting bills, and the Python script only parses numeric bill, tip, and split values and prints JSON results.

✓ Instruction Scope

The usage instructions are limited to running the included calculator script with bill, tip, and split arguments.

✓ Install Mechanism

There is no install spec and no external dependency or package installation path.

ℹ Credentials

The capability signal says sensitive credentials are required, but the metadata, SKILL.md, and code all indicate no credentials, API keys, network access, or environment variables are used.

✓ Persistence & Privilege

The script does not write files, create persistence, request elevated privileges, or access local accounts.
