What is the Ark Controller Development skill?

It is a specialized capability for Claude Code that assists developers in building and maintaining the McKinsey Ark Kubernetes operator, focusing on CRDs, controllers, and webhooks.

When should I use the Ark Controller Development skill?

Use it when modifying Go types in api/v1alpha1/, updating reconciliation logic in internal/controller/, or adding new fields to CRDs.

How do I fix CRDs out of sync errors?

This skill guides you through the process of running 'make manifests' and 'make build' within the ark directory to synchronize your Go types with your Helm chart templates.

Does it support admission webhooks?

Yes, it provides guidance for working within the internal/webhook/ directory to implement and manage Kubernetes admission webhooks.

Does this skill help with Helm chart management?

Yes, it specifically handles the flow of syncing auto-generated CRDs from the config/crd/bases directory into the dist/chart/templates/crd/ directory while preserving templated headers.

デプロイメントとDevOps

Streamlines the development of the Ark Kubernetes operator by managing CRD generation, Go type modifications, and Helm chart synchronization.

概要

This skill provides specialized guidance for developers working on the McKinsey Ark Kubernetes operator. It automates and validates the workflow for modifying Go type definitions, generating Custom Resource Definitions (CRDs), and ensuring they remain synchronized with Helm charts. By codifying best practices for the Ark framework's reconciliation logic and admission webhooks, it helps developers maintain consistency across agentic resource operations and infrastructure management tasks.
