Arcana OS

AI · Agent infrastructure

An open-source multi-agent operating system: a cast of agents, each shaped by a tarot archetype that defines its voice and behavior, and a meta-agent that sees it all, handling memory, tools, identity, and guardrails so your agents don't have to. Local-first, and works with local or hosted models.

What I built

Highlights

  • Published as a library plus CLI, installable as packages; 22 archetype configurations generate each agent's system prompt to tune behaviour.
  • Built a model gateway with adapters so agents run against local or hosted models interchangeably.
  • Built a federated memory layer over tiered SQLite and vector stores with a wikilink knowledge graph.
  • Built a tool gateway with declarative guardrails enforced before execution, an SSRF-guarded egress envelope for network tools, and a symlink-safe workspace path jail with capped recursion for filesystem tools.
