Building multi-agent AI systems with cognition, memory, and ontology-grounded retrieval.
Multi-agent systems: agent cognition (persona, emotion, memory, theory-of-mind), harness execution engines, and forge engineering — agents that rewrite their own harness under benchmark-gated control.
RAG and knowledge graphs: one-shot GraphRAG, ontology build + search toolkits, ontology-grounded retrieval, document AI pipelines.
Open source and research: xgen-ontology / xgen-omnifuse / xgen-harness / Agethos on PyPI, multi-award academic publications.
| Project | Description | Links |
|---|---|---|
| xgen-omnifuse | Backend-agnostic one-shot GraphRAG — fuses vector + graph (label / class enumeration / relation) seeds with MMR diversity into a single synthesis; zero-infra (in-memory BM25) or any SPARQL/Fuseki. Plus Vault, an omnifuse-native memory (fuse / surface). Extracted from production ontology GraphRAG |  |
| xgen-ontology | Backend-agnostic ontology / knowledge-graph toolkit — build a clean KG from documents or tables (extract / entity-resolution / dedup / is-a induction / quality), then search it with one-shot GraphRAG. Zero infra (in-memory), any SPARQL store. The BUILD half to omnifuse's search |  |
| xgen-harness | Declarative LLM agent execution engine (harness engineering) — declare a HarnessConfig, get a 10-stage pipeline. Multi-provider, capability-based tool matching, compile workflows to installable MCP wheels |
 |
| JINXUS | Hyper-personalized multi-agent AI assistant — 28 agents, virtual pixel office, 225 tools, autonomous execution |    |
| Agethos | A brain for AI agents — OCEAN personality, PAD emotion, memory stream, Hebbian learning, vicarious learning, cross-platform export |  |
| forge-engineering | Forge Engineering — a meta-engineering discipline above harness engineering: agents that rewrite their own harness under versioned, benchmark-gated control | |
