## Why get_latest_updates is rated Low

This tool queries an external API (Perplexity Sonar) to retrieve informational content about CSS. It does not create, modify, delete, or execute code; it only reads and returns data. Even if the underlying API call fails or returns unexpected results, no irreversible changes occur. The blast radius of misuse is minimal—an agent might receive outdated or irrelevant CSS information, but no system state is altered.

From the tool's own definition: "Tool description explicitly states it 'Fetches recent news and updates' about CSS features—a retrieval operation with no side effects. The verb 'Fetches' indicates data retrieval only."

## Use case

AI agents call get_latest_updates to retrieve information from Css Tutor 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)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Css Tutor:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_latest_updates": {}
  }
}
```
