Two corrections. **1. Sophia was written from recall, not from the source.** Reworked her identity and voice against the Golden Girls canon: - **She has a Brooklyn accent, not a Sicilian one.** She left Sicily in the 1920s and spent seventy years in New York; Estelle Getty played her explicitly as Brooklyn Italian-American. This is the single most common way to get her wrong, so it is now stated in the tone line, repeated in Avoid, and has its own failure mode. - **"Picture it" is a parable, not a catchphrase.** It opens a scene that ends in a moral answering the question actually asked. The failure mode is using it as a verbal tic with no story behind it. - Added the real biography (Grisanti, Salvadore, Clinton Avenue, Dorothy / Gloria / Phil, the stroke that removed her filter, Shady Pines, chef at the Golden Palace, the bamboo handbag) and the canon behaviours worth having: Sicilian curses, grudges, the mafia joke, serial embellishment with famous acquaintances. - New example interaction demonstrating a "Picture it" that earns its place. **2. Agents no longer get told who they replaced.** Provenance muddies the voice, invites comparison to a character that no longer exists, and costs context — an agent only needs to know who they *are*. Removed the lineage sentences from Sophia's bible and prompt, and retroactively from Watson (Seneca) and David (Bowie), including the LLM-facing shared.md directory and the personal.md "Replaced agents" section. Watson's substantive framing guidance is preserved, only the who-came-before is gone. Provenance now lives in exactly two places: the schema Version History and the git log. New docs/roster-changes.md captures the practice — the fictional-character casting rule and why it exists, when retiring is justified, that a 2:1 merge is legitimate, that node ownership transfers with no migration because constraints are label-keyed, that historical Note tags are left alone, and a checklist of everywhere a roster change actually reaches (spoiler: every agent prompt embeds the team roster, across all three teams and every runtime and deploy repo).

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 assistantdocs/{team}/team.md— team overview, responsibility matrix, handoff patternsdocs/{team}/subagents.md— catalog of team-scoped subagents and when to delegate to themdocs/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.
Assistants are fictional characters — real people carry baggage that arrives with the name and can change after the fact, while a character has canon to write against. Adding, replacing, or retiring one touches far more files than it looks like (every agent prompt embeds the team roster) — see docs/roster-changes.md for the practice and the checklist.
Personal Team

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.
