check-deployment-status

name	check-deployment-status
description	Check the health and sync status of all ArgoCD applications across clusters. Identifies out-of-sync, degraded, or unhealthy deployments and provides actionable remediation steps. Use when monitoring deployments, troubleshooting sync failures, or verifying environment health after a release.

Check Deployment Status

Retrieve and analyze the current state of all ArgoCD-managed applications. Surface any that are OutOfSync, Degraded, Missing, or Unknown, and provide clear next steps.

Instructions

1. List all ArgoCD applications using the ArgoCD agent's MCP tools. Request application name, project, sync status, health status, and target revision.
2. Categorize results into:
   • Healthy & Synced - no action needed
   • OutOfSync - drift detected between desired and live state
   • Degraded / Unhealthy - runtime health issues (crashloops, pending pods, failed probes)
   • Missing / Unknown - application or resources cannot be found
3. For each unhealthy application, provide:
   • Application name and namespace
   • Current sync and health status
   • Last sync timestamp and result
   • Resource-level details (which pods/deployments are failing)
   • Suggested remediation (sync, rollback, check resource limits, etc.)
4. Summary table at the top with total counts per status category.

Output Format

## Deployment Status Summary

| Status        | Count |
|---------------|-------|
| Healthy       | 42    |
| OutOfSync     | 3     |
| Degraded      | 1     |
| Missing       | 0     |

### Issues Requiring Attention

#### 1. my-app (namespace: production)
- **Sync Status**: OutOfSync
- **Health**: Degraded
- **Last Sync**: 2026-02-08T14:23:00Z (Failed)
- **Details**: Deployment `my-app` has 0/3 ready replicas. Pod `my-app-7d4b8c` in CrashLoopBackOff.
- **Recommended Action**: Check container logs for startup errors. Verify resource limits and environment variables.

Examples

• "Show me the status of all ArgoCD applications"
• "Are there any deployments that are out of sync?"
• "Check deployment health after the last release"
• "Which applications are degraded in the staging cluster?"

Guidelines

• Always paginate results (default page size: 20) to avoid OOM with large application counts
• Group results by project or cluster when there are more than 50 applications
• Highlight time since last successful sync for OutOfSync apps
• If all applications are healthy, confirm with a brief positive summary rather than listing every app
• When degraded apps are found, check for recent deployment events that may correlate
