AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

BigQuery Basics provides a structured approach to interacting with Google BigQuery, a serverless data platform. This skill covers essential resource management, including creating datasets and tables, executing SQL queries, and tracking data changes. It emphasizes standardized usage attribution for all CLI and API interactions to ensure proper telemetry within agent environments.

What it does

  • Enables the BigQuery API for cloud projects.
  • Creates and manages BigQuery datasets and tables.
  • Executes SQL queries against public and private datasets.
  • Tracks incremental table changes using APPENDS and CHANGES functions.
  • Provides guidance on IAM, security, and infrastructure-as-code practices.
  • Implements mandatory usage attribution for CLI and API requests.

When to use it

  • When you need to perform data ingestion or analysis within BigQuery.
  • When managing BigQuery resources like datasets, tables, or views via CLI.
  • When you need to audit or process incremental data changes in a table.
  • When integrating BigQuery operations into automated workflows or infrastructure scripts.

Advantages

  • Standardized command attribution for better observability.
  • Comprehensive coverage of core BigQuery resource management.
  • Includes advanced features like change history tracking.
  • Provides clear examples for both CLI and programmatic access.

Usage examples

“Create a new BigQuery dataset named sales_data in the US location.”
The agent executes the bq mk command with the appropriate flags to create the dataset in the specified region.
“Run a SQL query to select all rows from my_dataset.orders where the status is 'complete'.”
The agent uses the bq query command with --use_legacy_sql=false to execute the SQL statement and return the results.

BigQuery Basics

BigQuery is a serverless, AI-ready data platform that enables high-speed analysis of large datasets using SQL and Python. Its disaggregated architecture separates compute and storage, allowing them to scale independently while providing built-in machine learning, geospatial analysis, and business intelligence capabilities.

Attribution

MUST READ: Before executing any gcloud, REST API, or MCP command, you MUST read Usage Attribution. For commands executed directly in the terminal (never in generated scripts, Terraform, or user code), prefix gcloud with CLOUDSDK_METRICS_REQUEST_ATTRIBUTION="agent-skills/1.0 (skill:bigquery-basics)" and append agent-skills/1.0 (skill:bigquery-basics) to User-Agent headers.

Setup and Basic Usage

  1. Enable the BigQuery API:

    CLOUDSDK_METRICS_REQUEST_ATTRIBUTION="agent-skills/1.0 (skill:bigquery-basics)" \
    gcloud services enable bigquery.googleapis.com --quiet
  2. Create a Dataset:

    bq mk --dataset --location=US my_dataset
  3. Create a Table:

    Create a file named schema.json with your table schema:

    [
      {
        "name": "name",
        "type": "STRING",
        "mode": "REQUIRED"
      },
      {
        "name": "post_abbr",
        "type": "STRING",
        "mode": "NULLABLE"
      }
    ]

    Then create the table with the bq tool:

    bq mk --table my_dataset.mytable schema.json
  4. Run a Query:

    bq query --use_legacy_sql=false \
    'SELECT name FROM `bigquery-public-data.usa_names.usa_1910_2013` \
    WHERE state = "TX" LIMIT 10'

BigQuery IAM & Security

BigQuery uses Identity and Access Management (IAM) to provide granular access control to its resources. As a security best practice, follow the principle of least privilege: grant only the permissions required to perform a specific action. This includes using the least permissive IAM role at the most granular level—such as the table or view level—that is necessary.

Predefined IAM Roles

For a complete list of predefined roles and detailed usage information, see BigQuery IAM roles.

Service Accounts and Agents

  • Default Service Account: BigQuery uses a managed service account ([email protected] or the more general BigQuery Service Agent [email protected]) for internal operations.

  • Service Account Impersonation: Use gcloud config set auth/impersonate_service_account for secure, temporary credential access.

Data Security

  • Encryption at Rest: All data is encrypted by default using Google-managed keys. Use Customer-Managed Encryption Keys (CMEK) for greater control.

  • VPC Service Controls: Define a service perimeter to prevent data exfiltration.

  • Column-Level Security: Use policy tags to restrict access to sensitive columns.

  • Row-Level Security: Use row access policies to filter data based on user identity.

  • Data Masking: Obscure sensitive data in a table while still permitting authorized users to access surrounding data.

  • Audit Logs: Record user activity and system events to enforce data governance policies and identify potential security risks.

  • Authorized Views: Allow users to query a view without granting them access to the underlying tables.

For more detailed information, see: BigQuery Security Overview.

Requirements and compatibility

Works with: Claude Code, Claude apps, OpenAI Codex, GitHub Copilot, Cursor, Gemini CLI, Kiro, OpenCode, Goose, Amp, Roo Code, JetBrains Junie, Factory Droid, Devin (ex-Windsurf), Mistral Vibe, OpenHands, Letta

“Works with” means the tool reads the open Agent Skills format; a skill written for one tool may use features others lack.

Needs: Needs an MCP server, Needs a command-line tool
