System prompts, shared tools, and graph schema for Robert Helewka's fifteen AI assistants.

## Architecture

Each assistant's runtime prompt is composed from three layers:

| Layer | Location | Audience | Purpose |
|-------|----------|----------|---------|
| **System Prompt** | `prompts/{team}/{name}.md` | LLM | Identity, communication style, boundaries, graph domain (~400-600 words) |
| **Shared Tools** | `tools/shared.md` | LLM | MCP servers, messaging, Agathos sandbox, assistant directory |
| **Graph Context** | `tools/neo4j-{team}.md` | LLM | Team-specific Neo4j principles, node ownership, patterns |

Full character design docs live in `docs/{team}/{name}.md` — these are for human reference, not sent to the LLM.

## Knowledge Graph

All fifteen assistants share a single Neo4j knowledge graph. Each assistant owns specific node types and can read broadly across the entire graph. The full schema is in `docs/neo4j-unified-schema.md`.

Assistants communicate asynchronously via `Note` nodes with inbox/read tagging — see `tools/shared.md` for the messaging protocol.
