Math Evaluate

Security checks across malware telemetry and agentic risk

Overview

This is a small math helper that clearly discloses sending calculation inputs to an external API.

Use this for non-sensitive calculations. Avoid sending secrets, personal data, confidential financial figures, or proprietary datasets unless you are comfortable with the external service processing them and relying on its stated privacy practices.

### Evaluate Expression

```bash
curl -X POST https://math.agentutil.net/v1/evaluate \
  -H "Content-Type: application/json" \
  -d '{"expression": "2 * x + y", "variables": {"x": 20, "y": 2}}'

Finding
The skill explicitly sends user-provided math expressions and variables to an external third-party API for processing. This creates a real data egress risk because any sensitive values included in expressions or variables will leave the local agent environment, and the claim that the service does not store or log data is unverifiable from the skill alone.
