/secondo Command Dependencies

This document lists the dependencies required for the /secondo command to function properly.

Node.js Dependencies

The authentication system (scripts/auth-cli.mjs) requires Node.js packages.

✅ Included in PR: A root package.json with express dependency is now included.

# Install all dependencies (from project root)
npm install

Required packages:

• express (^4.19.2) - Web framework for OAuth callback server
• Node.js built-ins (http, fs, os, path, child_process)

Note: The package.json includes "type": "module" to support ES modules used by auth-cli.mjs.

System Dependencies

HTTPie (Preferred)

# macOS
brew install httpie

# Ubuntu/Debian
apt-get install httpie

# Python (universal)
pip install httpie

curl (Fallback)

Usually pre-installed on most systems. If not:

# macOS
brew install curl

# Ubuntu/Debian
apt-get install curl

jq (JSON Processing)

Required for JSON parsing in the CLI script:

# macOS
brew install jq

# Ubuntu/Debian
apt-get install jq

Firebase Configuration

Set environment variables for Firebase authentication:

export FIREBASE_API_KEY="your-api-key"
export FIREBASE_AUTH_DOMAIN="your-project.firebaseapp.com"
export FIREBASE_PROJECT_ID="your-project-id"

Verification

Check Node.js Dependencies

# Verify express module can be required
node -e "require('express')" && echo "✅ express installed" || echo "❌ express missing"

# Test auth-cli.mjs loads without errors
node scripts/auth-cli.mjs
# Should show help message, not module resolution errors

Check System Tools

command -v http >/dev/null && echo "✅ HTTPie installed" || echo "❌ HTTPie missing"
command -v curl >/dev/null && echo "✅ curl installed" || echo "❌ curl missing"
command -v jq >/dev/null && echo "✅ jq installed" || echo "❌ jq missing"

Test Authentication (After Dependencies)

# Should show help/error, not crash
node scripts/auth-cli.mjs status

Complete Setup

# 1. Install Node.js dependencies (from the repository root)
npm install

# 2. Install system tools (if needed)
brew install httpie jq  # macOS
# or
apt-get install httpie jq  # Ubuntu/Debian

# 3. Set Firebase environment variables
export FIREBASE_API_KEY="your-key"
export FIREBASE_AUTH_DOMAIN="your-domain"
export FIREBASE_PROJECT_ID="your-project"

# 4. Test authentication
node scripts/auth-cli.mjs login

# 5. Test secondo command
${CLAUDE_HOME:-$HOME/.claude}/scripts/secondo-cli.sh "test question"

Troubleshooting

"Cannot find package 'express'"

Install Node.js dependencies from the project root:

npm install

"http: command not found"

The script will automatically fall back to curl. But for best experience:

brew install httpie  # or apt-get install httpie

"jq: command not found"

Install jq for JSON processing:

brew install jq  # or apt-get install jq

Firebase configuration errors

Check whether the existing configuration is present without printing values:

test -n "${FIREBASE_API_KEY:-}" && echo "FIREBASE_API_KEY is configured" || echo "FIREBASE_API_KEY is missing"
test -n "${FIREBASE_AUTH_DOMAIN:-}" && echo "FIREBASE_AUTH_DOMAIN is configured" || echo "FIREBASE_AUTH_DOMAIN is missing"
test -n "${FIREBASE_PROJECT_ID:-}" && echo "FIREBASE_PROJECT_ID is configured" || echo "FIREBASE_PROJECT_ID is missing"

Keep existing authorized configuration in its designated secure store. Never print or paste the API key; see the cloud-ops-credential-guard skill.
