Auto-Arch Tournament vs oh-my-claudecode

Auto-Arch Tournament is an autonomous research system where an AI agent iteratively proposes, implements, and validates microarchitectural improvements to a RISC-V CPU. Starting from a standard 5-stage pipeline, the loop runs hypotheses in parallel, each going through formal verification (53 symbolic checks), cycle-accurate simulation, multi-seed FPGA place-and-route, and CoreMark CRC validation. Only hypotheses that beat the current champion get merged; everything else gets discarded. Starting from 301 iterations/second, the system hit 577 iter/s (+92%) across 73 attempts in 9.8 hours — producing a design 26% faster and 40% smaller in LUTs than the baseline. The insight the author drives home is that the real innovation isn't the AI agent — it's the verifier. The orchestrator is hardcoded to prevent agents from manipulating their own evaluation gates, a simple but critical design constraint that turns a creative process into a trustworthy one. Without a rigorous verification harness, agent-driven optimization becomes a confidence trick. This is early but fascinating proof that AI-driven hardware design loops can produce commercially meaningful gains. The repo uses Claude Code or Codex as the coding agent, SystemVerilog for the RTL, and standard open-source EDA tooling (Yosys, nextpnr, Verilator). It's a compelling template for anyone building agentic optimization loops where correctness matters.

oh-my-claudecode (OMC) is a plugin and CLI framework that adds intelligent multi-agent orchestration to Claude Code. It introduces a staged Team Mode pipeline where 19 specialized Claude agents collaborate on shared task lists—routing simple work to Haiku while sending complex reasoning to Opus—cutting token spend by 30–50% without sacrificing quality. The system ships with magic keywords that unlock escalating levels of autonomy: `ralph` for a persistent task-completion loop, `ulw` for ultra-work mode, and `autopilot` for fully hands-off feature development. A real-time HUD shows active agent count, token burn, and task queue status in your terminal statusline. The framework also supports mixed-model workflows where Claude, Codex, and Gemini agents run concurrently via tmux workers. Built by Yeachan-Heo, OMC reached 23k stars in under a week—largely riding the same wave as its sibling project oh-my-codex. Unlike oh-my-codex (which targets OpenAI's Codex CLI), OMC is tightly integrated with Claude Code's native teams API and memory system, making it the go-to extension layer for Claude Code power users who want true parallel agent pipelines.
