Runs a real safety-relevant preflight (checks ~/.claude/settings.json for a conflicting Snowflake MCP server before touching anything) and explicitly warns the fictional 'pip install snowflake-cortex-code' package doesn't exist — a concrete hallucination trap a generic baseline answer fell into.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Output vs. baseline 8/10
  • Docs & honesty 5/5

What Cortex Setup does

Detects the current OS, checks for an existing (conflicting) Snowflake MCP server in ~/.claude/settings.json, then installs the Snowflake CLI (snow) and Cortex Code CLI (cortex) via the repo's bundled install.sh/install.ps1 or official installer, and verifies the install. Triggers when cortex is missing, routing fails, or the user asks to set up Cortex Code / Snowflake.

How to install Cortex Setup

git clone https://github.com/Snowflake-Labs/snowflake-ai-kit
cd snowflake-ai-kit
mkdir -p ~/.claude/skills
cp -r plugins/cortex-code/skills/cortex-setup ~/.claude/skills/cortex-setup

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Cortex Setup

  • /cortex-setup Installs Snowflake CLI and Cortex Code CLI, OS-aware, with MCP-conflict guard.

It also activates on plain-language prompts like these:

  • cortex: command not found, can you help me set it up on my Mac?
  • I need to install the Snowflake CLI and Cortex Code CLI on this box
  • Set up Cortex Code for me, I don't have snow or cortex installed yet

Frequently asked questions

Is the Cortex Setup skill free?
Yes. The skill itself is free from Snowflake-Labs/snowflake-ai-kit. SkillProof publishes the install command and an independent test verdict at no cost.
Does Cortex Setup work with Claude Code?
We tested it with Claude Code 2.x (agent harness) on Jul 16, 2026. Verdict: Tested · Works. Runs a real safety-relevant preflight (checks ~/.claude/settings.json for a conflicting Snowflake MCP server before touching anything) and explicitly warns the fictional 'pip install snowflake-cortex-code' package doesn't exist — a concrete hallucination trap a generic baseline answer fell into.
What is the Cortex Setup SkillProof Score?
9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.
How do I install Cortex Setup?
Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
Can I use Cortex Setup with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
