## Why get_pull_request_full_diff is rated Low

This tool retrieves and returns the full diff of a pull request, which is purely informational with no side effects. It does not create, modify, delete, or execute anything. While the description is empty, the name and server context clearly indicate a read-only data retrieval operation. Low severity because unauthorized access to diffs poses limited immediate risk compared to other tool categories.

From the tool's own definition: "Tool name 'get_pull_request_full_diff' indicates retrieval of diff data with no modification. Server description confirms it supports 'fetching diffs' as a read operation."

## Use case
