+[Google BigQuery](https://cloud.google.com/bigquery) is Google Cloud's fully managed, serverless data warehouse designed for large-scale data analytics. BigQuery lets you run fast SQL queries on massive datasets, making it ideal for business intelligence, data exploration, and machine learning pipelines. It supports standard SQL, streaming inserts, and integrates with the broader Google Cloud ecosystem.
+
+In Sim, the Google BigQuery integration allows your agents to query datasets, list tables, inspect schemas, and insert rows as part of automated workflows. This enables use cases such as automated reporting, data pipeline orchestration, real-time data ingestion, and analytics-driven decision making. By connecting Sim with BigQuery, your agents can pull insights from petabytes of data, write results back to tables, and keep your analytics workflows running without manual intervention.
+{/* MANUAL-CONTENT-END */}
+
 ## Usage Instructions
 
 Connect to Google BigQuery to run SQL queries, list datasets and tables, get table metadata, and insert rows.
