Cortex Code in Claude Code¶

The Cortex Code in Claude Code plugin detects Snowflake-related prompts in your Claude Code session and routes them to the Cortex Code CLI, where Snowflake-specific skills handle the request. Prompts that aren’t related to Snowflake stay in Claude Code, so you can keep one workflow for both general coding and Snowflake tasks.

How it works¶

When you enter a prompt in Claude Code, the plugin runs a lightweight keyword filter to decide whether the prompt is Snowflake-related. If it is, the plugin starts a Cortex Code CLI session, runs the request with the CLI’s built-in Snowflake skills, and returns the result to your Claude Code session. If the prompt isn’t Snowflake-related, Claude Code handles it normally.

You can also route a prompt to Cortex Code explicitly, bypassing the automatic detection:

$cortex-run show me my warehouses and their current state

Prerequisites¶

Before you install the plugin, make sure that:

• Claude Code (https://www.claude.com/product/claude-code) is installed.
• The Cortex Code CLI (cortex) is installed and available on your PATH.
• You have a Snowflake connection configured in ~/.snowflake/connections.toml. To add one, run snow connection add.

Install the plugin¶

Install the plugin from the Claude plugin marketplace (https://claude.com/plugins/snowflake-cortex-code). In Claude Code, run:

claude plugin install snowflake-cortex-code@claude-plugins-official

Use the plugin¶

After the plugin is installed, ask Snowflake questions naturally in Claude Code. The plugin detects Snowflake intent and routes those prompts to Cortex Code. For example:

Show me my Snowflake warehouses
What databases do I have access to?
List all tables in my current schema
Create a dynamic table that refreshes hourly

Prompts that aren’t related to Snowflake, such as “fix the bug in auth.py” or “write a unit test,” stay in your Claude Code session.
