AWS Labs open-source (5k+★): one harness-neutral core turns Claude Code/Codex/Cursor/Copilot/Kiro/opencode into structured, verifiable delivery workflows via `aidlc config --harness` + doctor—install script, not a new agent.
Open team chat where you @-mention Claude Code/Codex/Pi/Goose in one Room; agents open corners to plan/build/test and bring a single approve-merge decision—multiplayer harness instead of single-player agent sessions.
iOS app that remotes into your own Claude Code host so you can kick off tasks, approve steps, watch live previews/terminal, and keep progress from your phone—self-hosted control plane, not a cloud sidecar.
US lab Reflection open-sourced Beam (501B MoE / 23B active, 1M context, Apache 2.0) for coding and long-horizon agents, with day-0 vLLM/SGLang/Transformers support, Mirror CLI harness, and 40+ inference partners including OpenRouter and Ollama.
