What is the core functionality of GitOps tools like Argo CD and Flux?

While GitOps tracks changes in Git, its core functionality isn't just generating human-readable summaries of human-made changes but enforcing the Git state.

GitOps replaces manual operations with automated reconciliation based on Git, but it doesn't use an agent to track Git commands in the sense of B.

Automatically creating pull requests for outdated dependencies is a function of dependency management tools or bots, not the core continuous synchronization principle of GitOps.

GitOps tools operate by continuously observing the desired state of a system, defined declaratively in Git, and comparing it against the actual state of the cluster. If a drift is detected, they either notify or automatically reconcile the cluster's state to match the Git repository, ensuring the system is always in the desired configuration.
