## Why review_changes is rated Low

The tool reads and analyzes working directory changes (via git diff) to produce a code review. This is a read-only inspection operation with no side effects. The server description confirms it works by reading 'actual code changes using git diff'. No writes, executions, or destructive actions are implied.

From the tool's own definition: "'Review the changes in my working directory' — reviewing implies reading/inspecting code changes, consistent with the server's stated purpose of generating reviews from git diff output."

## Use case

AI agents call review_changes to retrieve information from MCP Server PR Pilot 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)
