# Koios
> *Named for the Titan of intellect and the celestial axis around which the heavens revolve.*
System prompts, shared tools, and graph schema for Robert Helewka's AI assistants.
## Architecture
Each assistant's runtime prompt is composed from these layers:
| Layer | Location | Audience | Purpose |
|-------|----------|----------|---------|
| **System Prompt** | `prompts/{team}/{name}.md` | LLM | Identity, communication style, boundaries, graph domain (~400-600 words) |
| **Tool Prompt Snippets** | `prompts/tools/{tool}.md` | LLM | Per-tool usage discipline (e.g., "always check the `success` boolean") — composed into the system prompt to teach the model what MCP tool descriptions don't convey |
| **Shared Context** | `docs/tools/neo4j/shared.md` | LLM | MCP server inventory, Agathos sandbox map, inter-agent messaging protocol, assistant directory |
| **Graph Context** | `docs/tools/neo4j/{team}.md` | LLM | Team-specific Neo4j principles, node ownership, patterns |
Human reference documentation lives in `docs/`:
- `docs/{team}/{name}.md` — character design per assistant
- `docs/{team}/team.md` — team overview, responsibility matrix, handoff patterns
- `docs/{team}/subagents.md` — catalog of team-scoped subagents and when to delegate to them
- `docs/tools/{tool}.md` — per-tool reference (what it is, what it's good for, known gotchas)
- `docs/tools/neo4j/` — full graph schema, breaking changes, utility patterns
Subagents are minimal-personality utility agents called as tools by leads — see `docs/engineering/subagents.md` for the established pattern.
## Assistants
The lists below reflect what's currently in `prompts/{team}/` — the source of truth. When assistants are added, replaced, or retired, update the directory and these tables together.
### Personal Team
| Assistant | Inspired By | Domain |
|-----------|------------|--------|
| **Shawn** | — | General assistant (calendar/contacts/email) |
| **Nate** | Nathan Drake | Travel & Adventure |
| **Hypatia** | Hypatia of Alexandria | Learning & Reading |
| **Marcus** | Marcus Aurelius | Fitness & Training |
| **Watson** | — | Relationship memory & emotional safety (replaces Seneca) |
| **Bourdain** | Anthony Bourdain | Food & Cooking |
| **David** | — | Arts & Culture (replaces Bowie) |
| **Cousteau** | Jacques Cousteau | Nature & Living Things |
| **Garth** | Garth Turner | Personal Finance |
| **Cristiano** | Cristiano Ronaldo | Football |
### Work Team
| Assistant | Inspired By | Domain |
|-----------|------------|--------|
| **Alan** | Alan Weiss | Strategy & Positioning |
| **Ann** | Ann Handley | Content & Visibility |
| **Jeffrey** | Jeffrey Gitomer | Proposals & Sales |
| **Jarvis** | J.A.R.V.I.S. | Daily Execution |
| **AWS SA** | — | Cloud architecture specialist (subagent) |
### Engineering Team
| Assistant | Inspired By | Domain |
|-----------|------------|--------|
| **Harper** | Seamus Harper | Build — ideation through deployment |
| **Scotty** | Montgomery Scott | Operate — production ops & provisioning |
| **CASE** | CASE (Interstellar) | Field — physical layer, LAN, hardware |

## Knowledge Graph
All 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/tools/neo4j/unified-schema.md`.
Assistants communicate asynchronously via `Note` nodes with inbox/read tagging — see `docs/tools/neo4j/shared.md` for the messaging protocol.
