## TL;DR

Argo CD sync and health status gives agents concrete GitOps evidence before they modify manifests, restart workloads, or assume a deployment is broken.

## Core Explanation

Argo CD compares desired state from Git with live Kubernetes state. For agents, the useful evidence is not just the manifest content; it is the application name, target revision, sync status, health status, resource tree, operation history, ignored differences, and any custom health checks.

An OutOfSync application may be a real drift, an expected pending rollout, or a comparison difference caused by another controller. A Degraded or Progressing health status may point to Kubernetes resource conditions rather than a Git diff. Agents should preserve both dimensions before proposing remediation.
