BigQuery Expert

justvinhhere's BigQuery Expert, a Claude Code plugin with five skills, six slash commands and three agents for working in Google BigQuery. The skills switch on by themselves when you write a query, talk about partitioning or ask about costs. It's a community project, not a Google product. What you can do with it - Generate optimized BigQuery SQL from a plain-language description, or convert queries from PostgreSQL, MySQL, Snowflake, Redshift or SQL Server - Review SQL for 11 BigQuery anti-patterns, such as SELECT * on a single table, and get before-and-after rewrites - Design tables with time-unit, integer-range or ingestion-time partitioning, clustering, nested and repeated fields, and the right data types - Estimate what a query or table will cost, compare on-demand and editions pricing, and cut bytes billed with materialized views, caching and storage settings - Get working examples of STRUCT, ARRAY and UNNEST, MERGE, scripting, JSON functions, BigQuery ML, search indexes and vector search How it works - Install in Claude Code: /plugin marketplace add justvinhhere/bigquery-expert, then /plugin install bigquery-expert@justvinhhere-bigquery-expert - Commands: /bigquery-expert:bq-generate, bq-review, bq-optimize, bq-design-table, bq-estimate-cost and bq-explain - Agents review every SQL file in a project, audit table schemas, or find the most expensive queries Good to know - It works on the SQL and descriptions you give it; it doesn't connect to your BigQuery project - Apache-2.0 licensed
