 This Gemini CLI extension provides a set of tools to interact with [Google Cloud Spanner](https://cloud.google.com/spanner/docs) instances. It allows you to manage your databases, execute queries, and explore schemas directly from the [Gemini CLI](https://google-gemini.github.io/gemini-cli/), using natural language prompts.

 ## Why Use the Spanner Extension?
 
 * **Natural Language Management:** Stop wrestling with complex commands. Explore schemas and query data by describing what you want in plain English.
 * **Seamless Workflow:** As a Google-developed extension, it integrates seamlessly into the Gemini CLI environment. No need to constantly switch contexts for common database tasks.
 * **Code Generation:** Accelerate development by asking Gemini to generate data classes and other code snippets based on your table schemas.
