Welcome to Vibe Coding 2.0, an interactive, AI-guided agent experience designed for Snowflake events and summit booths. This repository contains the complete package to run the guided 4-phase vibe coding challenge where attendees build and run a Streamlit application locally.

This project bundles everything required to run the booth experience seamlessly:

• SKILL.md: The declarative instructions defining the Vibe Coding AI Agent's persona, knowledge base, phases, and rules.
• MCP Server (.cortex-plugin/mcp-server): A Model Context Protocol server exposing custom tools to the Cortex Agent:
  • roll_challenge: Generates the random theme and requirements.
  • start_local_streamlit: Runs the local Streamlit application.
  • validate_app: Verifies code correctness and logic.
• app.py: The dynamic workspace file where the agent writes the Streamlit app.
• Automation Scripts: Helper shell scripts to manage the booth laptop lifecycle.

Run these steps once on the booth laptop before the event/session starts.

Ensure the laptop has the following installed:

• Node.js (>= 18) & npm
• Python 3 (>= 3.8)
• Snowflake CLI (pip install snowflake-cli-labs)
• Streamlit (pip install streamlit)
• Cortex CLI

Workshop identity (VIBE_WH / VIBE_DB.APPS / VIBE_ROLE / VIBE_USER) must exist before any booth laptop can authenticate. The provisioning script lives at ../snowflake-vibecoding/setup.sql — run it once per Snowflake account.

./setup-laptop.sh

On first run this:

• Generates a fresh rsa_key.p8 / rsa_key.pub in the repo root. The private key is git-ignored and stays on the laptop; the public key is committed so operators can audit which key is in use.
• Prints an ALTER USER VIBE_USER SET RSA_PUBLIC_KEY = '...' statement that an ACCOUNTADMIN must run to register the key.
• Writes a vibecoding connection to ~/.snowflake/config.toml.
• Registers the MCP server, pre-approves its tools, and drops a populated .env.
• Installs a vibe shell alias that launches ./booth.sh.

snow connection test -c vibecoding

To start a new session for an attendee, run:

./booth.sh

This script will:

1. Reset app.py to a clean slate.
2. Stop any running Streamlit processes.
3. Dynamically generate settings.json and skills.json with correct absolute paths.
4. Launch the Cortex CLI preloaded with the Vibe Coding skill and MCP tools.

Once the interactive Cortex terminal is open, invoke the skill:

/vibe-coding

The agent will greet the attendee with high energy, roll for the challenge theme, and guide them step-by-step through the coding challenge!

If you need to reset the workspace between attendees without relaunching the CLI, run:

/reset

You can also run ./reset.sh directly from a shell.
