git_diff_staged_tool
AI agents call git_diff_staged_tool to retrieve information from MCP Git Commit Generator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on the tool name, this appears to retrieve and display the diff of staged (indexed) changes in a Git repository, which is a read-only operation with no side effects. The 'staged' qualifier indicates it shows changes added to the index but not yet committed.
From the tool's definition Tool name: git_diff_staged_tool — 'diff' implies reading/comparing staged changes; no description provided.
