 | Agent | Description |

 | **@debugger** | Goes beyond reading error messages. Uses your call stacks, variable state, and diagnostic tools to walk through error diagnosis systematically across your solution. |
+| **@git** | Reviews your local uncommitted changes and surfaces feedback as inline comments in the editor and in the Git Changes experience. |
 | **@profiler** | Connects to Visual Studio's profiling infrastructure to identify bottlenecks and suggest targeted optimizations grounded in your codebase, not generic advice. |
 | **@test** | Generates unit tests tuned to your project's framework and patterns, not boilerplate that your CI rejects. |
 | **@modernize** | (.NET and C++ only) Handles framework and dependency upgrades with awareness of your actual project graph. Flags breaking changes, generates migration code, and follows your existing patterns. |

 ## Revert, reset, or amend a commit
 
 When you double-click a **Commit**, Visual Studio opens its details in a separate tool window. From here you can revert the commit, reset (undo) the commit, amend the commit message, or create a tag on the commit. When you select a changed file in the commit, Visual Studio opens the side-by-side **Diff** view of the commit and its parent.
