System Design

  • Virtual Filesystem Context: Unifies memories, resources, and skills under a hierarchical viking:// URI namespace. Agents navigate context deterministically using filesystem primitives (ls, tree, find) rather than relying purely on vector embeddings.
  • Tiered Context Disclosure: Structures information into L0 (Abstract), L1 (Overview), and L2 (Detailed specification) tiers to protect agent context windows.
  • Directory-Recursive Retrieval: Preserves spatial and relational context across adjacent documents during queries.
  • Auditable Trajectories: Leaves transparent, step-by-step retrieval logs for post-hoc error analysis and evaluation.
  • Ecosystem: Integrated with Hermes Agent, deer-flow, and enterprise agent frameworks.
