WHAT IT DOES

What git_diff_staged does on GitHub

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

RISK

Why git_diff_staged is rated Low

This tool queries and displays git staging area changes—a read-only operation with no side effects. It cannot modify, delete, or execute code. The blast radius of misuse is minimal since the agent can only view staged changes, not apply them or access sensitive data beyond what is already staged.

From the tool's definition Tool name 'git_diff_staged' and description 'Git diff staged' indicate this retrieves staged changes in a git repository. The 'diff' command shows differences between versions without modifying data.

Attacks that exploit this kind of access
