Show HN: Intelligent proxy for human-in-the-loop agents written in Rust

Arch moves the critical but crufty work around safety, observability, and routing of prompts outside business logic. Its a uniquely intelligent infrastructure primitive, engineered with purpose-built fast LLMs [3] for tasks like intent detection over multi-turn, parameter identification and extraction, triggering single/multiple function calls, and offers convenience features to auto dispatch LLM calls for summarization based on data from your APIs via system prompts configured in archgw.
