Check Prerequisites

Verify all required tools are installed and guide installation of missing dependencies.

Prerequisites

None - this skill helps you install prerequisites!

Error Logging

Follow the Error Logging convention in AGENTS.md. Log file prefix: routing-prerequisites.

Workflow

Step 1: Check All Prerequisites

Goal: Identify which tools are installed and which are missing

Actions:

1. Check which container runtimes are installed:

   # Check Cortex Code CLI
   cortex --version 2>/dev/null && echo "Cortex Code: INSTALLED" || echo "Cortex Code: NOT FOUND"
   
   # Check Podman
   podman --version 2>/dev/null && echo "Podman: INSTALLED" || echo "Podman: NOT FOUND"
   
   # Check Docker (optional if Podman is installed)
   docker --version 2>/dev/null && echo "Docker: INSTALLED" || echo "Docker: NOT FOUND"
   
   # Check container runtime is running (Podman or Docker)
   podman info >/dev/null 2>&1 && echo "Podman Daemon: RUNNING" || docker info >/dev/null 2>&1 && echo "Docker Daemon: RUNNING" || echo "Container Runtime: NOT RUNNING"
   
   # Check Snowflake CLI
   snow --version 2>/dev/null && echo "Snowflake CLI: INSTALLED" || echo "Snowflake CLI: NOT FOUND"
   
   # Check Git
   git --version 2>/dev/null && echo "Git: INSTALLED" || echo "Git: NOT FOUND"
   
   # Check GitHub CLI (optional)
   gh --version 2>/dev/null && echo "GitHub CLI: INSTALLED" || echo "GitHub CLI: NOT FOUND (optional)"
   

2. Check Snowflake CLI connections:

   snow connection list 2>/dev/null || echo "No Snowflake connections configured"
   

3. Present results to user in a summary table:

   | Prerequisite | Status | Required | |--------------|--------|----------| | Cortex Code CLI | ✅/❌ | Yes | | Podman | ✅/❌ | Yes (or Docker) | | Docker | ✅/❌ | Yes (or Podman) | | Container Runtime | ✅/❌ | Yes | | Snowflake CLI | ✅/❌ | Yes | | Snowflake Connection | ✅/❌ | Yes | | Git | ✅/❌ | Yes | | GitHub CLI | ✅/❌ | No (optional) |

4. If all required prerequisites are installed: Inform user they are ready to proceed and skip to Verification section.

5. If any required prerequisites are missing: Proceed to Step 2.

Output: Prerequisites status summary

Step 2: Installation Wizard

Goal: Guide user through installing missing prerequisites

Actions:

1. Ask user which missing prerequisites they want to install now.

2. For each selected prerequisite, provide installation guidance:

Cortex Code CLI Installation

• Installation: See Cortex Code documentation
• Verify: cortex --version

Container Runtime Installation (Podman or Docker)

Podman (recommended - no daemon required):

• macOS:

  brew install podman
  podman machine init
  podman machine start
  

• Windows: Download Podman Desktop: https://podman-desktop.io/downloads

• Linux:

  # Ubuntu/Debian
  sudo apt-get update
  sudo apt-get install podman
  
  # RHEL/CentOS/Fedora
  sudo dnf install podman
  

• Verify: podman --version && podman info

Docker (alternative if Podman is not available):

• macOS:

  brew install --cask docker
  

  Or download Docker Desktop: https://docs.docker.com/desktop/install/mac-install/

• Windows: Download Docker Desktop: https://docs.docker.com/desktop/install/windows-install/

• Linux:

  # Ubuntu/Debian
  sudo apt-get update
  sudo apt-get install docker.io
  sudo systemctl start docker
  sudo systemctl enable docker
  

• Post-install: Start Docker Desktop (macOS/Windows) or the daemon (Linux)

• Verify: docker --version && docker info

Snowflake CLI Installation

• All platforms:

  pip install snowflake-cli-labs
  

• Configure connection:

  snow connection add
  

  Follow prompts to enter:

  • Connection name (e.g., my-snowflake)
  • Account identifier
  • Username
  • Authentication method (password, SSO, key-pair)

• Verify: snow --version && snow connection list

Git Installation

• macOS:

  brew install git
  

  Or install Xcode Command Line Tools: xcode-select --install

• Windows: Download from https://git-scm.com/download/win

• Linux:

  # Ubuntu/Debian
  sudo apt-get install git
  
  # RHEL/CentOS
  sudo yum install git
  

• Configure:

  git config --global user.name "Your Name"
  git config --global user.email "[email protected]"
  

• Verify: git --version

GitHub CLI Installation (Optional)

• macOS:

  brew install gh
  

• Windows:

  winget install --id GitHub.cli
  

• Linux:

  # Ubuntu/Debian
  curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg
  echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" | sudo tee /etc/apt/sources.list.d/github-cli.list > /dev/null
  sudo apt update
  sudo apt install gh
  

• Authenticate:

  gh auth login
  

• Verify: gh --version

Output: Installation commands executed or provided

Step 3: Verify Installation

Goal: Confirm all prerequisites are now installed correctly

Actions:

1. Re-run the checks from Step 1

2. If all required prerequisites pass:

   • Congratulate user
   • Inform them they can now run: build routing solution

3. If any required prerequisites still missing:

   • List the remaining missing items
   • Offer to retry installation or provide manual installation links

Output: Final verification status

Stopping Points

• ✋ After Step 1: Review which prerequisites need to be installed
• ✋ After Step 2: Confirm installations completed without errors

Verification

After completion, all these commands should succeed:

cortex --version        # Cortex Code CLI  
podman --version        # Podman (or docker --version for Docker)
podman info             # Podman running (or docker info for Docker)
snow --version          # Snowflake CLI
snow connection list    # At least one connection configured
git --version           # Git

Note: Either Podman or Docker is required - you don't need both.

Common Issues

Issue: brew command not found (macOS)

• Solution: Install Homebrew: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Issue: Docker daemon not running

• Solution:
  • macOS/Windows: Open Docker Desktop application
  • Linux: sudo systemctl start docker

Issue: Permission denied for Docker

• Solution: Add user to docker group: sudo usermod -aG docker $USER then log out and back in

Issue: pip command not found

• Solution: Install Python first, or use pip3 instead

Issue: snow CLI prints version update warnings

• Solution: Set export SNOWFLAKE_CLI_NO_UPDATE_CHECK=1 in your shell profile to suppress update check noise during builds

Issue: Snowflake connection fails

• Solution: Verify account identifier format (e.g., ACCOUNT.REGION or ORG-ACCOUNT)

Output

All prerequisites verified and installed. Environment ready for deploying Route Optimizer.
