## 🚨 Top 3 CRITICAL Priorities

### 1. 🔴 Secret Management & Security
**Impact**: CRITICAL | **Effort**: 2 weeks

```bash
# Immediate Actions:
✅ Mask tokens in logs
✅ Add detect-secrets in pre-commit
✅ Document best practices
```

### 2. 🔴 Insufficient Test Coverage (86%)
**Impact**: CRITICAL | **Effort**: 3 weeks

```bash
# Goal: 90%+
📈 tools.py: 50% → 100%
📈 __init__.py: 83% → 100%
📈 CLI commands: +10% coverage
```

### 3. 🟡 Inconsistent Logging (loguru + logging)
**Impact**: HIGH | **Effort**: 2 weeks

```bash
# Standardize on loguru
🔧 Migration: 5 files to fix
🔧 Centralized config to create
```
