## 🔧 Usage Examples

### Example 1: Complete File Workflow
```typescript
// Setup
await sys_create_directory({ path: "D:/projects/myapp" });

// Copy template
await sys_copy_path({
  source: "D:/templates/base-project",
  destination: "D:/projects/myapp",
  recursive: true
});

// Verify
const { exists } = await sys_path_exists({ path: "D:/projects/myapp/package.json" });
if (!exists) {
  console.error("Template copy failed!");
}

// Work on project...

// Archive when done
await sys_move_path({
  source: "D:/projects/myapp",
  destination: "D:/archive/myapp_2025-01-07"
});

// Clean up
await sys_delete_path({
  path: "D:/projects/temp",
  recursive: true
});
```

### Example 2: Configuration & Monitoring
```typescript
// Check system config
const { config } = await sys_get_config();
console.log(`KERNL v${config.version}`);
console.log(`Database: ${config.database.path}`);
console.log(`Features enabled: ${Object.entries(config.features)
  .filter(([k, v]) => v)
  .map(([k]) => k)
  .join(', ')}`);

// Monitor tool usage
const { stats } = await sys_get_usage_stats({ limit: 50 });
console.log(`\nUsage Statistics:`);
console.log(`  Total calls: ${stats.totalCalls}`);
console.log(`  Success rate: ${stats.successRate}%`);
console.log(`  Average duration: ${stats.averageDuration}ms`);

// Find most used tools
console.log(`\nTop 5 Tools:`);
stats.topTools.slice(0, 5).forEach((tool, i) => {
  const breakdown = stats.toolBreakdown[tool.name];
  console.log(`  ${i + 1}. ${tool.name}`);
  console.log(`     Calls: ${tool.calls}, Success: ${breakdown.successes}/${breakdown.calls}`);
  console.log(`     Avg duration: ${breakdown.avgDuration}ms`);
});

// Discover available tools
const { totalTools, toolsByCategory } = await sys_get_tool_info();
console.log(`\nTool Registry: ${totalTools} tools across ${Object.keys(toolsByCategory).length} categories`);
```

### Example 3: System Administration
```typescript
// Get all tools in System category
const systemTools = await sys_get_tool_info({
  category: "System",
  detailed: true
});

console.log(`System Tools (${systemTools.totalTools}):`);
for (const [name, details] of Object.entries(systemTools.toolDetails)) {
  console.log(`\n${name}:`);
  console.log(`  ${details.description}`);
}

// Check usage of system tools
const { stats } = await sys_get_usage_stats();
const systemToolStats = Object.entries(stats.toolBreakdown)
  .filter(([name]) => name.startsWith('sys_'))
  .sort((a, b) => b[1].calls - a[1].calls);

console.log(`\nSystem Tool Usage:`);
for (const [name, stats] of systemToolStats) {
  console.log(`  ${name}: ${stats.calls} calls (${stats.avgDuration.toFixed(0)}ms avg)`);
}

// Adjust configuration based on usage
if (stats.toolBreakdown['sys_copy_path']?.calls > 100) {
  console.log('\nHeavy file operations detected!');
  await sys_set_config_value({
    key: 'limits.maxFileSize',
    value: 52428800 // Increase to 50MB
  });
  console.log('Increased max file size limit to 50MB');
}
```

## 💡 Lessons Learned

### What Went Well
1. **Leverage existing code** - `core.ts` already had most functions
2. **Consistent patterns** - Same error handling, return format across all tools
3. **Comprehensive documentation** - Rich tool descriptions help users
4. **Incremental building** - Each phase builds on previous work
5. **Zero technical debt** - No shortcuts, no compromises

### Design Decisions
1. **In-memory configuration** - Fast, no I/O overhead
2. **Dot notation** - Intuitive config key format (`features.chromeExport`)
3. **Usage tracking** - Automatic, passive, zero-overhead
4. **Tool registry** - Enables self-documentation and discovery
5. **Category organization** - Clear tool organization by purpose

### Performance Optimizations
1. **Map-based storage** - O(1) lookups for config and stats
2. **Limited history** - Keep only recent 100 durations per tool
3. **Lazy computation** - Calculate stats on-demand
4. **Memory management** - Auto-cleanup of old activity
5. **Efficient serialization** - JSON for config, structured data
