What cortex-code does

The skill uses LLM-based routing: mentions of Snowflake databases, dynamic tables, Cortex Search, or Analyst invoke Cortex Code in headless mode. Local files, other databases, and web tasks stay with the main agent. On first load, discover_cortex.py caches Cortex skill metadata in ~/.cache/cortex-skill/; repeat queries skip initialization.

A security wrapper offers three approval modes: prompt asks the user before execution, auto and envelope_only approve automatically and write audit logs. Mode is set in config.yaml (defaults to prompt if the file is absent). Requires Cortex Code CLI installed; without it, routing will fail.

What it helps with

  • delegate Snowflake SQL queries to a specialized agent
  • call Cortex AI functions and Snowpark without switching tools
  • log warehouse operations for compliance audit
  • separate Snowflake tasks from local development in one agent
  • cache Cortex skill metadata to skip repeated discovery

Example prompts for the agent

  • Show schemas in my Snowflake warehouse
  • Run a Cortex Search query on the orders table
  • Build a Snowpark model for sales forecasting
