Key Change Highlights

• The addition of AGENTS.md files across the project structure suggests the introduction or formalization of guidelines related to agents within the Snap Hutao application. The specific content of these files is not available in the provided patch, but their presence indicates a focused effort on managing and defining agent behavior or responsibilities within different modules of the application. Without knowing the context of the files, it's impossible to determine the impact of overall codebase.
