📊 What Makes Us Different
Feature
🏛️ Traditional
🛡️ Harmony
🧠 Error Memory
❌ Start fresh every time
✅ Learns from mistakes
🔄 Circuit Breaker
❌ Repeat failures endlessly
✅ Stops after 3 failures
🎯 Intent Detection
❌ Manual agent selection
✅ Auto-routing
✅ Quality Gates
❌ "It works" = done
✅ Triple validation (DEV+TEST+QA)
💾 Context Persistence
❌ Lost between sessions
✅ 3-tier memory
📈 Pattern Learning
❌ No learning
✅ Gets smarter over time
Before installing Harmony, ensure you have these mandatory dependencies :
Tool
Purpose
Install
Node.js Runtime (npx)
nodejs.org
jq JSON processing
sudo apt install jq / brew install jq
yq YAML processing
sudo apt install yq / brew install yq
# Verify installation# v18+ recommended# 1.6+# any version
⚠️ Why jq and yq? Harmony uses these tools for high-performance configuration parsing and YAML/JSON manipulation. Without them, installation will fail.
# Install (requires jq + yq)# Start coding# Session kickoff# Interactive menu# Error memory dashboard30 seconds to install. Lifetime of saved debugging time.
