 ## How it works
 
 You keep the shared assets and `sync-config.json` in one source repository. A workflow in that repository calls `team-ai-sync`. The tool reads the config, checks each target repository, copies the configured files into a sync branch, and opens or updates pull requests or merge requests for the destination teams to review.
