## Session 6 — Jupyter Live Kernel + Obsidian + arXiv (June 15, 2026)

### Exercises
| # | Skill | Result |
|---|-------|--------|
| 1 | **Jupyter Live Kernel** | Server v2.19.0 running at :8888 ✅ |
| 2 | **Obsidian** | No vault found (not configured) |
| 3 | **arXiv** | Searched LLM agent papers, found relevant multi-agent paper ✅ |
| 4 | **Semantic Scholar** | API accessible for citations/impact analysis ✅ |

### Jupyter Kernel Success
```python
# Fleet SSH probe via Jupyter kernel - first live kernel execution!
hosts = 12 targets
✅ 12/12 SSH reachable - 100% uptime
```
- Server: localhost:8888 with token `hermes123`
- Hamelnb script at `~/.agent-skills/hamelnb/`
- WebSocket transport, stateful REPL

### arXiv Paper Found
**"Small LLMs Are Weak Tool Learners: A Multi-LLM Agent"** (2401.07324)
- Proposes decomposing LLM agent into planner/caller/summarizer
- Directly relevant to Hermes multi-skill architecture
- Full abstract and PDF accessible
