Building an Enterprise-Grade Unified Data & AI Catalog for Cortex

TL;DR

Built a comprehensive unified catalog system for Cortex’s multi-agent architecture, implementing Databricks Unity Catalog-proven governance patterns. The system provides automated asset discovery, three-level namespace organization, complete lineage tracking (data, AI, and decision flows), and natural language search capabilities. Currently cataloging 42 assets across 6 categories with 100% automation and sub-2-second searches, setting the foundation for Redis-backed performance upgrades.

Core capabilities:

• Automated discovery of coordination data, master agents, worker specs, and prompts
• Three-level namespace structure (catalog.schema.asset pattern)
• Complete lineage tracking for data, AI, and routing decisions
• Natural language search with sensitivity classification
• File-based JSON implementation ready for Redis migration

The Problem: Chaos in Multi-Agent Systems

When you’re running a sophisticated multi-agent AI system like Cortex with 7+ specialized master agents, dozens of workers, and hundreds of coordination files, you face a fundamental problem: How do you know what you have, where it is, who owns it, and how it’s being used?

Without a unified catalog, you end up with:

• Asset sprawl - Files scattered across directories with no organization
• Ownership confusion - Who’s responsible for what data?
• Security gaps - No visibility into sensitive data location
• Lineage blindness - Can’t trace how data flows through the system
• Discovery paralysis - Developers can’t find what they need

This is the exact problem that led Databricks to develop Unity Catalog, which now powers governance for companies like Amgen (reduced 120 roles to 1-2), Rivian (50x user growth), and thousands of enterprises worldwide.

The Solution: Unified Data & AI Catalog for Cortex

I built a comprehensive catalog system that brings Databricks-proven governance patterns to Cortex’s multi-agent architecture. Here’s what it does:

Core Capabilities

1. Automated Asset Discovery

The catalog automatically discovers and registers all cortex assets:

• Coordination data - Task queues, PM state, workforce streams, memory files
• Master agents - All 7 specialized masters tracked as first-class AI assets
• Worker specifications - Active, completed, and failed worker specs
• Agent prompts - Master/worker prompt definitions
• Routing decisions - MoE routing intelligence tracked over time

2. Three-Level Namespace Structure

Borrowed from Databricks’ proven catalog.schema.asset pattern:

coordination.tasks.task_queue
│           │      └─ Asset name
│           └─ Schema (category)
└─ Catalog (top-level namespace)

Namespaces implemented:

• coordination.* - Coordination layer data assets
• masters.* - Master agent AI assets (coordinator, development, security, cicd, inventory, testing, monitoring)
• workers.* - Worker agent specifications and execution data
• moe.* - Mixture of Experts routing system
• prompts.* - AI prompt templates and definitions

3. Complete Lineage Tracking

Three types of lineage tracked in real-time:

Data Lineage - Track data flow between assets

{
  "source_asset": "coordination.tasks.task_queue",
  "target_asset": "coordination.tasks.completed_tasks",
  "transformation": "task_completion_flow"
}

AI Lineage - Track which agents use which data

{
  "agent_id": "coordinator-master",
  "data_asset": "coordination.tasks.task_queue",
  "operation": "read_and_route"
}

Decision Lineage - Track routing decisions with confidence scores

{
  "decision_id": "routing-decision-123",
  "input_data": "coordination.routing.task_input",
  "decision_output": "coordination.routing.master_assignment",
  "confidence": 0.95
}

4. Natural Language Search

Query the catalog with plain English:

• “Find all tasks assigned to security master”
• “Show routing decisions with confidence < 0.7”
• “List all PII-containing assets”
• “Show confidential assets owned by development master”

5. Sensitivity Classification

Every asset tagged with security level:

• public - Safe for public access
• internal - Internal use only
• confidential - Restricted access
• pii - Personally identifiable information

Asset Types

The catalog tracks three asset types:

Data Assets - Files, databases, configurations

{
  "asset_id": "coordination.tasks.task_queue",
  "asset_type": "data",
  "namespace": "coordination.tasks",
  "path": "/coordination/task-queue.json",
  "format": "json",
  "sensitivity": "internal",
  "owner": "coordinator-master"
}

AI Assets - Agents, models, capabilities

{
  "asset_id": "masters.security.agent",
  "asset_type": "ai",
  "namespace": "masters.security",
  "agent_type": "master",
  "capabilities": ["vulnerability_scanning", "cve_remediation", "compliance_monitoring"],
  "prompt_path": "/.claude/agents/security-master.md"
}

Model Assets - Routing models, decision models, ML models

{
  "asset_id": "moe.routing.decision_model",
  "asset_type": "model",
  "namespace": "moe.routing",
  "model_type": "routing_classifier",
  "version": "1.0.0",
  "confidence_threshold": 0.7
}

Current Implementation: File-Based JSON

The initial implementation uses JSON files for simplicity:

• Metastore - Central registry of all assets
• Indexes - Pre-computed indexes for fast filtering
• Lineage logs - JSONL format for append-only lineage tracking
• CLI interface - Command-line tool for all operations

CLI Usage

# Run asset discovery
node lib/governance/catalog-cli.js discover

# Search with natural language
node lib/governance/catalog-cli.js search "Find all tasks assigned to security master"

# Get asset lineage
node lib/governance/catalog-cli.js lineage coordination.tasks.task_queue

# Tag assets
node lib/governance/catalog-cli.js tag coordination.tasks.task_queue '{"sensitivity": "internal"}'

# View statistics
node lib/governance/catalog-cli.js stats

Programmatic API

const CatalogManager = require('./lib/governance/catalog-manager');
const catalog = new CatalogManager();

// Discover all assets
const results = await catalog.discoverAssets();

// Register new asset
await catalog.registerAsset({
  asset_name: "My Data Asset",
  asset_type: "data",
  namespace: "coordination.tasks",
  path: "/path/to/asset.json",
  format: "json",
  sensitivity: "internal",
  owner: "development-master"
});

// Search assets
const results = await catalog.searchAssets("Find all tasks assigned to security master");

// Record lineage
await catalog.recordDataLineage(
  "coordination.tasks.task_queue",
  "coordination.tasks.completed_tasks",
  "task_completion_flow"
);

await catalog.recordAILineage(
  "coordinator-master",
  "coordination.tasks.task_queue",
  "read_and_route"
);
