gcloud-auth-verification

What problem does it solve? When gcloud, bq, dataform, or Python libraries fail with authentication errors like "No credentialed accounts" or "DefaultCredentialsError", this Skill guides the diagnosis and resolution of missing Google Cloud credentials without guesswork. ## Core Features & Use Cases - Error Recognition: Identifies common authentication failure messages from gcloud CLI, bq, and Python google.auth exceptions. - Status Verification: Runs gcloud auth list to confirm whether credentials are missing or whether the issue is actually IAM permissions (e.g., 403 errors on an authenticated account). - Guided Remediation: Instructs the user to run gcloud auth login and gcloud auth application-default login themselves, since credentials must be established by the user, not by code. - Use Case: A notebook fails with google.auth.exceptions.DefaultCredentialsError. The Skill verifies no ADC exists, then directs the user to set up Application Default Credentials before retrying. ## Quick Start Check my Google Cloud authentication status and help me fix the DefaultCredentialsError I'm getting in my Python notebook.
