name: ops-devops-platform description: Production-grade DevOps patterns with Kubernetes 1.34+, Terraform 1.9+, Docker 27+, ArgoCD/FluxCD GitOps, SRE, eBPF-based observability, AI-driven monitoring, CI/CD security, and cloud-native operations (AWS, GCP, Azure, Kafka).

DevOps Engineering — Quick Reference

This skill equips Claude with actionable templates, checklists, and patterns for building self-service platforms, automating infrastructure with GitOps, deploying securely with DevSecOps, scaling with Kubernetes, ensuring reliability through SRE practices, and operating production systems with AI-driven observability.

Modern Best Practices (December 2025): Kubernetes 1.34 (in-place Pod resource updates GA, 1.35 releasing Dec 17), Docker 27 with BuildKit optimizations, Terraform 1.9+ with improved provider ecosystem, ArgoCD 2.14/FluxCD 2.5 GitOps patterns, eBPF-based observability (Cilium, Hubble), and AI-driven AIOps for incident correlation.

When to Use This Skill

Claude should invoke this skill when users request:

• Platform engineering patterns (self-service developer platforms, internal tools)

• Infrastructure as Code patterns (Terraform, K8s manifests, policy as code)
• CI/CD pipelines with DevSecOps (GitHub Actions, security scanning, SAST/DAST/SCA)
• SRE incident management, AI-driven alerting, escalation, or postmortem templates
• eBPF-based observability (Cilium, Hubble, kernel-level insights, OpenTelemetry)
• Kubernetes operational patterns (day-2 operations, resource management, workload placement)
• Cloud-native monitoring (Prometheus, Grafana, unified observability platforms)
• Team workflow, communication, handover guides, and runbooks
