Drift Cortex

> "The only AI memory system that understands code as code, not text."

Drift Cortex is the memory layer for Drift, providing persistent, intelligent memory that makes AI agents truly understand your codebase.

Features

- 9 Memory Types: Core, Tribal, Procedural, Semantic, Episodic, PatternRationale, ConstraintOverride, DecisionContext, CodeSmell
- Bitemporal Tracking: Know when you learned something AND when it was true
- Self-Healing Validation: Memories stay synchronized with actual code
- Sleep-Inspired Consolidation: Episodic memories compress into semantic knowledge
- Intent-Aware Retrieval: Different intents weight different memory types
- Multi-Provider Embeddings: Local (Transformers.js), OpenAI, Ollama

Installation

``bash
pnpm add driftdetect-cortex
`

Quick Start

`typescript
import { Cortex } from 'driftdetect-cortex';

// Initialize
const cortex = await Cortex.create({
dbPath: '.drift/cortex/memory.db',
embeddingProvider: 'local', // or 'openai', 'ollama'
});

// Add tribal knowledge
await cortex.add({
type: 'tribal',
topic: 'authentication',
knowledge: 'Never store JWT secrets in environment variables on the client',
severity: 'critical',
});

// Retrieve context-aware memories
const memories = await cortex.retrieve({
intent: 'add_feature',
focus: 'user authentication',
maxTokens: 2000,
});
`

Memory Types

| Type | Purpose | Half-Life |
|------|---------|-----------|
| Core | Project identity, preferences | ∞ |
| Tribal | Institutional knowledge | 365 days |
| Procedural | How-to procedures | 180 days |
| Semantic | Consolidated knowledge | 90 days |
| Episodic | Interaction history | 7 days |
| PatternRationale | Why patterns exist | 180 days |
| ConstraintOverride | Approved exceptions | 90 days |
| DecisionContext | Human context for ADRs | 180 days |
| CodeSmell | Patterns to avoid | 90 days |
