From 99dba1d509dd53fc36a5b7fd97b16064a87705ad Mon Sep 17 00:00:00 2001 From: jbold Date: Sun, 8 Feb 2026 02:07:53 -0600 Subject: [PATCH 1/3] feat: implement Phases 1-3 (MVP core runtime) Phase 1 (Setup): config.rs with TOML loading, types.rs with shared message types, complete examples/config.toml, config integration in main.rs with CLI override support. Phase 2 (Foundational): LLM provider trait with Anthropic/OpenAI implementations, ChatSendParams parsing, auth and router tests (18 passing), lib.rs for integration test support. Phase 3 (US1 MVP): Wire chat.send end-to-end through router -> session -> LLM provider -> streaming WebSocket response. RpcResult enum for single vs streaming responses. Per-session message history. Assistant response collection and session persistence.
