For the Hitchhikers Project we aim to create an open-source, modular, and federated agent-based architecture centered on CrewAI.
The aim of the project is to create a Vibe Code Playground inside federated wiki, where the wiki acts both as a way to document and visualise the results of vibe-coding expereiments, and as a way to collaborate on the plans and prompts that the agents use to generate solutions.
The system should run locally on HomeLab hardware, support API access to Claude and OpenAI, and use n8n for flow automation and inter-node coordination. Individual HomeLabs can specialize using tools like Claude Code, LangGraph, and AutoGen, while Yam + Git provides a shared knowledge ledger.
# Reasons for Recommendation 1. **Open & Local-First** — All tools are open source or API-based, respecting self-hosted constraints. 2. **Modular & Composable** — Specialized agents can be upgraded or replaced independently. 3. **Federated by Design** — Homelabs can work offline or async and still collaborate via Git/Yam. 4. **Tool Diversity** — Combines strengths of Claude’s dev stack with the flexibility of CrewAI. 5. **Accessible for Contributors** — Visual workflows (n8n), shared wiki logs, and agent roles make it easy to contribute. 6. **Fun & Thematic** — Agent names and roles reflect the quirky spirit of *The Hitchhiker’s Guide*.
# Agent Roles
An Agent Role defines a specialized function for a homelab agent, such as planner, builder, reviewer, or researcher. Roles like Deep Thought, Slartibartfast, or Scribe help structure collaboration across nodes, with each role implemented via CrewAI, Claude Code, or hybrid agents.
# Interoperability - Use n8n to route tasks, triggers, and completions between nodes - Use Model Context Protocol (MCP) to link Claude Code agents and other tools - Communicate via local endpoints (e.g. `marvin-node.local/crewai/run`) - Store outputs in Markdown + Yam for paragraph-level federation and replay
