## Why demo_url_pulse is rated Low

This tool retrieves and returns static precomputed sample data. It performs no external calls, modifies no state, executes no code, and creates no financial obligations. It is a pure read operation providing demonstration data, analogous to a GET request to a public API endpoint. The 'demo' prefix and explicit mention of 'without payment' further confirm it is a safe, informational tool.

From the tool's own definition: "Tool returns precomputed sample data without payment, URL fetch, or side effects. Description: 'Return the fixed precomputed URL Pulse sample without payment or URL fetch.'"

## Use case
