Mandatory Step 0 pre-flight execution order and authentication verification for Google Cloud Platform (GCP), Application Default Credentials (ADC), gcloud CLI, Spark, Dataproc, BigQuery, GCS, and notebook runtimes. Use whenever interacting with GCP resources, running Spark/PySpark pipelines, BigQuery queries, GCS paths (gs://), or creating/running notebooks.

## Install

```sh
git clone https://github.com/GoogleCloudPlatform/data-agent-kit-plugin /tmp/data-agent-kit-plugin && ln -s /tmp/data-agent-kit-plugin/skills/google-cloud-auth-verification ~/.claude/skills/google-cloud-auth-verification
```

## From README

Google Cloud Authentication Guidelines Mandatory Pre-Flight Execution & Auth Hierarchy \[!IMPORTANT\] Pre-Flight Execution Priority Order: Before generating code, implementation plans, or executing tasks for any GCP or Notebook workload: Skip Pre-Flight Shell Probes When Live Notebook Execution or MCP Tools Are Available: When a live notebook cell execution tool (executecell / notebookexecutecell / notebookexecutecell) is available, or when the task is handled directly by a connected MCP tool (bigqueryexecutesql, bigquerygettableinfo, bigquerylisttableids, etc.), do NOT run a pre-flight gcloud auth list && gcloud config list shell probe. Instead, verify authentication reactively only if a cell execution or MCP tool call returns an authentication or credentials error (401, 403, DefaultCredentialsError, Reauthentication is needed).
