Dive into the innovative world of AI with a unique setup featuring two distinct agents operating on separate virtual private servers (VPS). The public agent, named nullclaw, is a compact 678 KB Zig binary that utilizes approximately 1 MB of RAM, seamlessly interacting with users through an Ergo IRC server. Visitors can engage with it via a gamja web client integrated into my website. Meanwhile, the private agent, known as ironclaw, manages email and scheduling tasks and is accessible exclusively through Tailscale using Google’s A2A protocol. The system leverages tiered inference models: Haiku 4.5 for efficient conversations and Sonnet 4.6 for tool utilization, capped at a budget-friendly $2 per day. This innovative A2A passthrough enables enhanced communication and functionality between the two agents, representing a fascinating advancement in AI technology.
