# Comprehensive Cache Cleaning Strategy

## Executive Summary

This document outlines a safe, prioritized approach to cleaning development caches based on the cache-cleaner skill. The strategy balances space recovery with operational safety.

---

## 1. Mode Selection: Safe vs Aggressive

### Recommendation: **Start with Safe Mode**

| Mode | Use Case | Risk Level |
|------|----------|------------|
| **Safe (default)** | Regular maintenance, first-time cleaning | Low |
| **Aggressive** | Emergency space recovery, stale environment reset | Medium-High |

**When to use Safe Mode:**
- Routine maintenance (recommended default)
- Unfamiliar environment
- Production-adjacent systems
- When you need verification after each step

**When to use Aggressive Mode:**
- Disk space emergency
- Known-safe development machine
- Before system reinstallation
- After verifying safe mode results first

---

## 2. Prioritized Cache Targets

### Tier 1: High Impact, Low Risk (Clean First)

| Cache Type | Command | Typical Size | Risk |
|------------|---------|--------------|------|
| **npm cache** | `--npm` | 100MB - 2GB | Low |
| **pip cache** | `--pip` | 50MB - 500MB | Low |
| **Temporary files** | Safe scan | Variable | Low |
| **Yarn cache** | `--yarn` | 100MB - 1GB | Low |

### Tier 2: Medium Impact, Medium Risk

| Cache Type | Command | Typical Size | Risk |
|------------|---------|--------------|------|
| **Docker** | `--docker` | 1GB - 10GB+ | Medium |
| **pnpm** | `--pnpm` | 100MB - 1GB | Low |
| **Maven/Gradle** | `--maven --gradle` | 500MB - 2GB | Low |

### Tier 3: Higher Risk (Clean Last or Selective)

| Cache Type | Command | Typical Size | Risk |
|------------|---------|--------------|------|
| **Homebrew** | `--homebrew` | 500MB - 2GB | Medium |
| **Podman** | `--podman` | 1GB - 10GB | Medium |
| **Conda** | `--conda` | 1GB - 5GB | Medium |

## 3. What to PRESERVE

### Always Exclude

```bash
# DO NOT CLEAN these locations
✓ node_modules/          # Active project dependencies
✓ .git/                  # Version control
✓ .venv/                 # Python virtual environments (active)
✓ vendor/                # PHP dependencies
✓ target/                # Rust/Go build output (if recent)
✓ .gradle/               # Active Gradle projects (check dates)
✓ .m2/                   # Only if not cached remotely
```

### Conditional Preservation

| Item | Preserve If... | Clean If... |
|------|---------------|-------------|
| `node_modules` | Active development | Abandoned/dead project |
| Docker images | Recently used (< 7 days) | Unused for 30+ days |
| pip cache | Slow network connection | Fast network available |
| Homebrew | Limited bandwidth | Unlimited connection |

---

## 4. Recommended Cleaning Sequence

### Phase 1: Assessment (Safe Mode)

```bash
# Step 1: Scan first to see what's available
./scripts/cache_cleaner.sh scan

# Step 2: Run safe mode with npm and pip only
./scripts/cache_cleaner.sh clean --npm --pip
```

### Phase 2: Medium-Risk Cleaning

```bash
# Step 3: Clean build tool caches
./scripts/cache_cleaner.sh clean --maven --gradle

# Step 4: Clean package manager (if needed)
./scripts/cache_cleaner.sh clean --yarn --pnpm
```

### Phase 3: Docker & Container Cleanup (Optional)

```bash
# Step 5: Only after verifying other steps work
./scripts/cache_cleaner.sh clean --docker
```

### Phase 4: Aggressive (Emergency Only)

```bash
# Only if space is still critical
./scripts/cache_cleaner.sh clean aggressive
```

---

## 5. Verification Steps

### Pre-Cleaning Checklist

- [ ] Document current disk usage: `df -h`
- [ ] Identify active projects with recent `node_modules`
- [ ] Check for ongoing builds/deploys
- [ ] Note any running Docker containers

### Post-Cleaning Verification

| Check | Command | Expected Result |
|-------|---------|-----------------|
| Disk space recovered | `df -h` | Free space increased |
| npm works | `npm --version` | Version displayed |
| pip works | `pip --version` | Version displayed |
| Docker works | `docker ps` | Container list (may be empty) |
| Homebrew works | `brew --version` | Version displayed |

### Functional Tests

```bash
# Test npm
npm list -g --depth=0

# Test pip  
pip list | head -5

# Test Docker (if cleaned)
docker images

# Verify no broken symlinks in common dirs
find ~ -maxdepth 3 -type l ! -exec test -e {} \; -print
```

---

## 6. Safety Checks

### Before Running Any Clean

1. **Check for running processes** using cache directories:
   ```bash
   lsof +D ~/.npm 2>/dev/null
   lsof +D ~/.cache/pip 2>/dev/null
   ```

2. **Verify no active builds**:
   ```bash
   ps aux | grep -E 'npm|gradle|maven|docker'
   ```

3. **Backup critical configs** (optional but recommended):
   ```bash
   cp ~/.npmrc ~/.npmrc.bak
   cp ~/.cache/pip/pip.log ~/.cache/pip/pip.log.bak 2>/dev/null
   ```

### Rollback Plan

If something breaks:
- npm: `npm cache verify` then `npm cache clean --force`
- pip: Reinstall packages as needed
- Docker: `docker pull` images again
- Homebrew: `brew update && brew upgrade`

---

## 7. Quick Reference Command Set

### Conservative (Start Here)
```bash
./scripts/cache_cleaner.sh clean --npm --pip
```

### Standard Maintenance
```bash
./scripts/cache_cleaner.sh clean --npm --pip --yarn --pnpm --maven --gradle
```

### Full Safe Clean
```bash
./scripts/cache_cleaner.sh clean --npm --pip --yarn --pnpm --docker --maven --gradle --homebrew
```

### Emergency Aggressive
```bash
./scripts/cache_cleaner.sh clean aggressive
```

---

## Summary

**Start conservative**, verify, then expand. The safe mode is designed for exactly this incremental approach. Most development machines will recover 2-10GB with Tier 1-2 cleaning alone.
