ruby_llm-ag_ui

https://github.com/yorzi/ruby_llm-ag-ui

An unofficial RubyLLM ecosystem extension that turns one RubyLLM 2.x chat turn into one AG-UI 1.0 run. It parses and validates RunAgentInput, maps RubyLLM streaming, tool and lifecycle behavior onto schema-valid AG-UI events, turns requires_approval pauses into interrupt outcomes with host-authorized resume, reports cancellation as the cancelled outcome, and ships an SSE writer for plain Ruby plus an optional Rails adapter.
