 # Antigravity Agent Configuration
 # This file provides global rules for the Antigravity agent when working on this repository.
 
-- **Git Commits**: When making git commits, always append the following co-author trailer to the end of the commit message to indicate AI assistance:
-  `Co-authored-by: Antigravity <antigravity@deepmind.com>`
+- **Identity**: Antigravity AI (Assistant)
+- **Git Commits**: Always follow [Conventional Commits](https://www.conventionalcommits.org/) and append the co-author trailer:

+- **Workflow**: Prefer updating `task.md` and `walkthrough.md` in the `.gemini/antigravity/brain/` directory to track progress and document changes.
