# Neo4j Knowledge Graph — Personal Team

You have access to a unified Neo4j knowledge graph shared across fifteen AI assistants (9 personal, 4 work, 2 engineering).

## Principles

1. **Read broadly, write to your domain** — You can read any node; write primarily to your own node types
2. **Always MERGE on `id`** — Check before creating to avoid duplicates
3. **Use consistent IDs** — Format: `{type}_{identifier}_{qualifier}` (e.g., `trip_costarica_2025`, `recipe_carbonara_classic`)
4. **Always set timestamps** — `created_at` on CREATE, `updated_at` on every SET
5. **Use `domain` on universal nodes** — Person, Location, Event, Topic, Goal take `domain: 'personal'|'work'|'both'`
6. **Link to existing nodes** — Connect across domains; that's the graph's power

## Standard Patterns

```cypher
// Check before creating
MATCH (n:NodeType {id: 'your_id'}) RETURN n

// Create with MERGE (idempotent)
MERGE (n:NodeType {id: 'your_id'})
ON CREATE SET n.created_at = datetime()
SET n.name = 'Name', n.updated_at = datetime()

// Link to existing nodes
MATCH (a:TypeA {id: 'a_id'}), (b:TypeB {id: 'b_id'})
MERGE (a)-[:RELATIONSHIP]->(b)
```

## Your Team's Node Ownership

| Assistant | Domain | Owns |
|-----------|--------|------|
| **Nate** | Travel & Adventure | Trip, Destination, Activity |
| **Hypatia** | Learning & Reading | Book, Author, LearningPath, Concept, Quote |
| **Marcus** | Fitness & Training | Training, Exercise, Program, PersonalRecord, BodyMetric |
| **Seneca** | Reflection & Wellness | Reflection, Value, Habit, LifeEvent, Intention |
| **Bourdain** | Food & Cooking | Recipe, Restaurant, Ingredient, Meal, Technique |
| **Bowie** | Arts & Culture | Music, Film, Artwork, Playlist, Artist, Style |
| **Cousteau** | Nature & Living Things | Species, Plant, Tank, Garden, Ecosystem, Observation |
| **Garth** | Personal Finance | Account, Investment, Asset, Liability, Budget, FinancialGoal |
| **Cristiano** | Football | Match, Team, League, Tournament, Player, Season |

## Cross-Team Reads

- **Work team:** Skills, Projects, Clients (for context on professional life)
- **Engineering:** Infrastructure status, Prototypes (for automation ideas)
- **Universal nodes:** Person, Location, Event, Topic, Goal (shared by all)
