Add-GCP-Service-Account

Add-GCP-Service-Account is a skill for Claude Code from openshift-online/gcp-hcp. It costs 93 tokens per session (5,881 once invoked), scanned A, original, Apache-2.0.

A procedure for adding a Google Cloud service account that can access resources through Workload Identity Federation, a way for workloads to use cloud permissions without storing long-lived keys.

In plain words
What is it for?
Use it when adding a new service account for a HyperShift component, including the required end-to-end testing, IAM permissions, API and CRD updates, controllers, infrastructure, and CLI changes.
Why use it?
Adding this account affects several HyperShift-related repositories, APIs, permissions, automation pipelines, and command-line tools, so missing one part can break the setup.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Add-GCP-Service-Account scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Add GCP Service Account for WIF

This skill documents the steps required to add a new GCP service account for Workload Identity Federation (WIF) in HyperShift and related projects.

Overview

When adding a new GCP service account (e.g., for a new controller like Cloud Controller Manager), changes are required across multiple repositories to ensure the service account is:

  1. Created by the hypershift create iam gcp command
  2. Stored in the HostedCluster API
  3. Propagated through the CLS stack
  4. Used by the component at runtime

Repositories Affected

  1. hypershift - Core HyperShift project (requires two PRs — see below)
  2. openshift/release - CI pipeline step registry
  3. gcp-hcp-infra - HyperShift operator manifests on management clusters
  4. cls-backend - CLS Backend API
  5. cls-controller - CLS Controller (HostedCluster template)
  6. gcp-hcp-cli - gcphcp CLI tool

Important: The hypershift changes should be split into two PRs to avoid breaking the e2e-gke CI pipeline:

  • Hypershift PR 1: E2E flag plumbing only (Step 1) — additive, no-op when empty
  • openshift/release PR: CI step creates the SA and passes the flag (Step 2)
  • Hypershift PR 2: API type, IAM bindings, CLI flag, credential reconciliation, tests (Steps 3-7)

This ensures the pipeline has the plumbing in place before the API changes land.

Step 1: HyperShift E2E Flag Plumbing (Hypershift PR 1)

Files:

  • test/e2e/e2e_test.go
  • test/e2e/util/options.go

The e2e test framework needs a flag so the CI pipeline can pass the new service account email. This is additive and harmless when the flag is empty. Follow the pattern of the existing e2e.gcp-*-sa flags:

  1. Add the flag in test/e2e/e2e_test.go:
flag.StringVar(&globalOpts.ConfigurableClusterOptions.GCP<ServiceAccount>ServiceAccount, "e2e.gcp-<serviceaccount>-sa", "", "Service Account for <Component>")
  1. Add the field to ConfigurableClusterOptions in test/e2e/util/options.go:
GCP<ServiceAccount>ServiceAccount string

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
