Argo CD Deployment Failed: AI SRE Agent AURA Finds and Fixes It
A deployment fails validation and the sync stops. Argo CD hands the report to AURA, which finds the wrong version, fixes it, and re-runs the sync.

Normally, a failed sync means a person opens the application, reads the hook logs, and works out which value is wrong. Here, the sync fail hook sends AURA a short failure report and an incident ID over the agent-to-agent protocol, then exits. It does not say how to investigate or what to change.
AURA works from that symptom. It checks the Argo CD operations and the hook logs, compares the evidence against live Kubernetes state in the demo namespace, and confirms the version mismatch. It updates the one config map it is allowed to change, from version 1 to version 2, and asks Argo CD for another sync. The pre-sync check passes and the application returns to synced and healthy. A final check confirms AURA still holds no wider write access.
The same run is recorded as a trace in Phoenix, so you can inspect what AURA did instead of relying on its final answer. Each model turn and each MCP tool call is a span carrying its request and its result, and the only two changes in the entire run are one config map update and one sync request.
AURA is built for platform engineers and SREs running Argo CD who want a failed deployment investigated and repaired inside limits they set, with a record of every step.
