Cortex Code plugin for Claude Code and OpenAI Codex

Route Snowflake work from Claude Code or OpenAI Codex to Cortex Code automatically. Ask about your data naturally — the plugin detects Snowflake intent and delegates to Cortex Code where 55+ built-in skills handle the work. Non-Snowflake prompts stay in your current agent.

How It Works

Two ways to route prompts to Cortex Code:

Auto-routing (default)

A lightweight keyword filter (prompt_filter.py) runs on every prompt. When it detects Snowflake-related patterns, it loads the cortex-router skill which delegates to Cortex Code.

Examples that auto-route:

  • "Show me my Snowflake warehouses"
  • "What databases do I have access to?"
  • "List all tables in my current schema"

Examples that stay in your agent:

  • "Read the config.json file"
  • "Fix the bug in auth.py"
  • "Write a Python unit test"

Explicit invocation ($cortex-run)

Type $cortex-run followed by your prompt to force routing to Cortex Code, bypassing the keyword filter. Useful when:

  • Auto-routing didn't pick up your prompt
  • You want to be explicit about using Cortex Code
  • Your prompt mixes Snowflake and non-Snowflake work

$cortex-run analyze query performance for the last 7 days
