## Why list_course_files is rated Low

This tool retrieves or enumerates course files, producing no side effects. It follows the Read category pattern of data retrieval operations. Confidence is moderately high despite empty description because the verb 'list' is unambiguous. Severity is low because reading study materials poses minimal risk even if misused by an AI agent.

From the tool's own definition: "Tool name 'list_course_files' contains the verb 'list', which is a canonical read operation that retrieves/queries data. The description is empty, but the name clearly indicates listing/querying existing course files without modification."

## Use case

AI agents call list_course_files to retrieve information from School MCP 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 School MCP:

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