01 / AI + OPEN SOURCE ENGINEERING ECOSYSTEM

Connected infrastructure
for autonomous AI work.

Rather than isolated utilities, my open-source work forms a cohesive local-first engineering stack: NodeNet maps code authority, LCDD governs living specs, Iritoken optimizes token budgets, OpenCraft Skills orchestrates execution, and AgentifAI + ai.log provide deep observability and on-device auditability.
