GCP Hosted Control Planes architecture, design decisions, and implementation plans
npx claudepluginhub openshift-online/gcp-hcp --plugin gcp-hcpUse when adding a new GCP service account for Workload Identity Federation (WIF) in HyperShift and related GCP HCP repositories. Covers API types, IAM bindings, CRD regeneration, CLS backend/controller propagation, and CLI updates across hypershift, gcp-hcp-infra, cls-backend, cls-controller, and gcp-hcp-cli.
Use when an implementation plan in gcp-hcp may have drifted from actual code, or when code may have drifted from the plan's design intent. Typically after a feature has landed or a PR has merged. Checks API surface, behavior, interfaces, and structure across repositories.
Use when working on GCP HCP-related code or design in any of the GCP HCP repositories: hypershift (platform/gcp/, GCP provider, GCP-related tests), gcp-hcp-infra (Terraform, ArgoCD, infrastructure), gcp-hcp-cli, cls-backend, cls-controller, or when creating or reviewing design decisions, or needing architectural context for GCP Hosted Control Planes on GKE. Accepts optional topic filter: networking, identity, observability, infrastructure, ingress, storage, operators, testing, automation, naming, dns, fleet, incidents, slo.
