## Why book_list_services is rated Low

This tool retrieves service information (duration and price) for informational purposes. It has no side effects, does not modify data, execute code, delete records, or commit financial transactions. The primary use case is to help an agent discover what services are available so it can make an informed booking decision.

From the tool's own definition: "Tool description states 'List one business's services' — a retrieval operation. No modification, deletion, or execution of external commands occurs."

## Use case

AI agents call book_list_services to retrieve information from Caboo without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

```json
{
  "version": "1",
