# 🛠️ Brainy Augmentation Developer Guide
> **How to create, test, and use augmentations in Brainy 2.0**
## Quick Start: Your First Augmentation
```typescript
import { BaseAugmentation, BrainyAugmentation, AugmentationContext } from '@soulcraft/brainy'
export class MyFirstAugmentation extends BaseAugmentation {
readonly name = 'my-first-augmentation'
readonly timing = 'after' as const // When to run: before | after | both
readonly operations = ['addNoun'] as const // Which operations to hook
readonly priority = 10 // Execution order (lower = first)
protected async onInit(): Promise<void> {
// Initialize your augmentation
console.log('MyFirstAugmentation initialized!')
}
async execute<T = any>(
operation: string,
params: any,
context?: AugmentationContext
): Promise<T | void> {
// Your augmentation logic
if (operation === 'addNoun') {
console.log('Noun added:', params.noun)
// You can access the brain instance
const stats = await context?.brain.getStatistics()
console.log('Total nouns:', stats.totalNouns)
}
}
protected async onShutdown(): Promise<void> {
// Cleanup
console.log('MyFirstAugmentation shutting down')
}
}
```
## Using Your Augmentation
```typescript
import { BrainyData } from '@soulcraft/brainy'
import { MyFirstAugmentation } from './my-first-augmentation'
const brain = new BrainyData()
// Register before init()
brain.augmentations.register(new MyFirstAugmentation())
await brain.init()
// Now your augmentation runs automatically!
await brain.addNoun('Hello World')
// Console: "Noun added: { id: '...', vector: [...], metadata: {} }"
```
---
## Augmentation Lifecycle
### 1. Registration Phase
```typescript
const aug = new MyAugmentation()
brain.augmentations.register(aug) // Before brain.init()!
```
### 2. Initialization Phase
```typescript
await brain.init() // Calls aug.initialize() internally
// Your onInit() method runs here
```
### 3. Execution Phase
```typescript
await brain.addNoun('data') // Your execute() method runs
```
### 4. Shutdown Phase
```typescript
await brain.shutdown() // Your onShutdown() method runs
```
---
## Timing Options
### `before` - Modify Input
```typescript
class ValidationAugmentation extends BaseAugmentation {
readonly timing = 'before' as const
async execute<T>(operation: string, params: any): Promise<any> {
if (operation === 'addNoun') {
// Validate and/or modify params
if (!params.content) {
throw new Error('Content required')
}
// Return modified params
return { ...params, validated: true }
}
}
}
```
### `after` - React to Results
```typescript
class LoggingAugmentation extends BaseAugmentation {
readonly timing = 'after' as const
async execute<T>(operation: string, params: any): Promise<void> {
if (operation === 'search') {
console.log(`Search for "${params.query}" returned ${params.result.length} results`)
}
// Don't return anything - just observe
}
}
```
### `both` - Before AND After
```typescript
class TimingAugmentation extends BaseAugmentation {
readonly timing = 'both' as const
private startTime?: number
async execute<T>(operation: string, params: any, context?: AugmentationContext): Promise<void> {
if (!this.startTime) {
// Before execution
this.startTime = Date.now()
} else {
// After execution
const duration = Date.now() - this.startTime
console.log(`${operation} took ${duration}ms`)
this.startTime = undefined
}
}
}
```
---
## Operation Hooks
### Core Operations You Can Hook
```typescript
readonly operations = [
'addNoun', // Adding data
'updateNoun', // Updating data
'deleteNoun', // Deleting data
'getNoun', // Retrieving data
'search', // Searching
'find', // Triple Intelligence queries
'addVerb', // Adding relationships
'deleteVerb', // Removing relationships
'clear', // Clearing data
'all' // Hook ALL operations
] as const
```
### Example: Multi-Operation Hook
```typescript
class AuditAugmentation extends BaseAugmentation {
readonly operations = ['addNoun', 'updateNoun', 'deleteNoun'] as const
async execute<T>(operation: string, params: any): Promise<void> {
// Log all data modifications
await this.logToAuditTrail(operation, params)
}
}
```
---
## Accessing Brain Context
```typescript
class ContextAwareAugmentation extends BaseAugmentation {
async execute<T>(
operation: string,
params: any,
context?: AugmentationContext
): Promise<void> {
// Access the brain instance
const brain = context?.brain
if (!brain) return
// Use any brain method
const stats = await brain.getStatistics()
const size = await brain.size()
const results = await brain.search('query')
// Access other augmentations
const cache = brain.augmentations.get('cache')
if (cache) {
await cache.clear()
}
}
}
```
---
## Real-World Examples
### 1. Backup Augmentation
```typescript
class BackupAugmentation extends BaseAugmentation {
readonly name = 'backup'
readonly timing = 'after' as const
readonly operations = ['addNoun', 'updateNoun', 'deleteNoun'] as const
readonly priority = 5
private changes = 0
private readonly backupThreshold = 100
async execute<T>(operation: string, params: any, context?: AugmentationContext): Promise<void> {
this.changes++
if (this.changes >= this.backupThreshold) {
await this.performBackup(context?.brain)
this.changes = 0
}
}
private async performBackup(brain?: any): Promise<void> {
if (!brain) return
const backup = await brain.backup()
await this.saveToCloud(backup)
console.log('Automatic backup completed')
}
}
```
### 2. Rate Limiting Augmentation
```typescript
class RateLimitAugmentation extends BaseAugmentation {
readonly name = 'rate-limit'
readonly timing = 'before' as const
readonly operations = ['search', 'find'] as const
readonly priority = 100 // High priority - run first
private requests = new Map<string, number[]>()
private readonly limit = 100 // 100 requests
private readonly window = 60000 // per minute
async execute<T>(operation: string, params: any): Promise<void> {
const now = Date.now()
const key = params.userId || 'anonymous'
// Get request timestamps
const timestamps = this.requests.get(key) || []
// Remove old timestamps
const recent = timestamps.filter(t => now - t < this.window)
// Check limit
if (recent.length >= this.limit) {
throw new Error('Rate limit exceeded')
}
// Add current request
recent.push(now)
this.requests.set(key, recent)
}
}
```
### 3. Encryption Augmentation
```typescript
class EncryptionAugmentation extends BaseAugmentation {
readonly name = 'encryption'
readonly timing = 'both' as const
readonly operations = ['addNoun', 'getNoun'] as const
readonly priority = 90 // Run early
async execute<T>(operation: string, params: any): Promise<any> {
if (operation === 'addNoun') {
// Encrypt before storing
if (params.metadata?.sensitive) {
params.content = await this.encrypt(params.content)
params.encrypted = true
}
return params
}
if (operation === 'getNoun' && params.result?.encrypted) {
// Decrypt after retrieval
params.result.content = await this.decrypt(params.result.content)
delete params.result.encrypted
return params.result
}
}
}
```
---
## Testing Your Augmentation
```typescript
import { describe, it, expect } from 'vitest'
import { BrainyData } from '@soulcraft/brainy'
import { MyAugmentation } from './my-augmentation'
describe('MyAugmentation', () => {
it('should hook into addNoun', async () => {
const brain = new BrainyData({ storage: 'memory' })
const aug = new MyAugmentation()
// Spy on the execute method
const executeSpy = vi.spyOn(aug, 'execute')
brain.augmentations.register(aug)
await brain.init()
// Trigger the augmentation
await brain.addNoun('test data')
// Verify it was called
expect(executeSpy).toHaveBeenCalledWith(
'addNoun',
expect.objectContaining({ content: 'test data' }),
expect.any(Object)
)
})
})
```
---
## Best Practices
### 1. Use Proper Timing
- `before`: Validation, modification, rate limiting
- `after`: Logging, metrics, side effects
- `both`: Timing, tracing, wrapping
### 2. Set Appropriate Priority
```typescript
// Priority guidelines
100: Critical (auth, rate limiting)
50: Important (validation, transformation)
10: Normal (logging, metrics)
1: Optional (debugging, tracing)
```
### 3. Handle Errors Gracefully
```typescript
async execute<T>(operation: string, params: any): Promise<void> {
try {
await this.riskyOperation()
} catch (error) {
// Log but don't break the main operation
console.error(`Augmentation error in ${this.name}:`, error)
// Optionally report to monitoring
this.reportError(error)
}
}
```
### 4. Be Performance Conscious
```typescript
class CachedAugmentation extends BaseAugmentation {
private cache = new Map<string, any>()
async execute<T>(operation: string, params: any): Promise<any> {
const key = this.getCacheKey(params)
// Check cache first
if (this.cache.has(key)) {
return this.cache.get(key)
}
// Expensive operation
const result = await this.expensiveOperation(params)
this.cache.set(key, result)
return result
}
}
```
### 5. Clean Up Resources
```typescript
protected async onShutdown(): Promise<void> {
// Close connections
await this.connection?.close()
// Clear intervals
clearInterval(this.interval)
// Flush buffers
await this.flush()
// Clear caches
this.cache.clear()
}
```

## FAQ
### Q: Can I modify the operation result?
**A**: Yes, if `timing: 'before'`, return modified params. If `timing: 'after'`, you can see but not modify results.
### Q: Can augmentations communicate?
**A**: Yes, through the context: `context.brain.augmentations.get('other-augmentation')`
### Q: What if my augmentation fails?
**A**: Handle errors internally. Don't break the main operation unless critical.
### Q: Can I use async operations?
**A**: Yes, everything is async-friendly.
### Q: How do I access storage directly?
**A**: Through context: `context.brain.storage` (but prefer using brain methods)
