## 🎯 Why We Built This

| 😤 The Pain | 🛡️ Harmony Solution |
|-------------|---------------------|
| Same bug keeps coming back | 🧠 **Error Memory** - Never repeat the same mistake |
| "Works on my machine" | ✅ **Quality Gates** - 100% verifiable criteria |
| Wrong AI agent activated | 🎯 **Intent Detection** - Right agent, right time |
| Lost context between sessions | 💾 **3-Tier Memory** - Persistent project knowledge |
| Locked to one IDE | 🔌 **Multi-IDE** - Claude Code, Cursor, Windsurf... |

## 📊 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 |
| 🛡️ Security Guards | ❌ Blind trust | ✅ Supply-chain + injection filtering |

---

## 🛡️ Security Guards

Harmony ships with two optional protection hooks that screen what enters and what gets installed:

| Guard | Protects against |
|-------|------------------|
| **supply-chain-guard** | Vulnerable / typosquatted packages, unpinned MCP servers, recently-published packages (cooling period), missing lock files, unofficial sources |
| **llm-output-sanitizer** | Prompt injection, data exfiltration, hidden Unicode, leaked secrets — in any **external** content (WebFetch, fetched URLs, external LLM responses) |

```bash
/hf:security:guards status     # See current state
/hf:security:guards off        # Disable all (zero perf impact)
/hf:security:guards mode llm-sanitizer strict   # Maximum coverage
```

> ⚠️ **Defense-in-depth, not a silver bullet.** These guards aim to **minimize the maximum number of injection and supply-chain attacks** — they do not guarantee 100% protection. Detection is pattern-based, so the scripts **must be kept up to date** as new attack techniques emerge. Always combine them with human review of generated code and installed dependencies.

## 📋 Prerequisites

Before installing Harmony, ensure you have these **mandatory dependencies**:

| Tool | Purpose | Install |
|------|---------|---------|
| **Node.js** | Runtime (npx) | [nodejs.org](https://nodejs.org/) |
| **jq** | JSON processing | `sudo apt install jq` / `brew install jq` |
| **yq** | YAML processing | `sudo apt install yq` / `brew install yq` |

```bash
# Verify installation
node --version    # v18+ recommended
jq --version      # 1.6+
yq --version      # any version
```

> ⚠️ **Why jq and yq?** Harmony uses these tools for high-performance configuration parsing and YAML/JSON manipulation. Without them, installation will fail.

---

## 🚀 Quick Start

```bash
# Install (requires jq + yq)
npx harmony-ai --full

# Start coding
/go                    # Session kickoff
/harmony               # Interactive menu
/harmony sentinel      # Error memory dashboard
```

**30 seconds to install. Lifetime of saved debugging time.**
