AI models rationalize their own code when reviewing it. Using three different CLIs for independent review effectively catches blind spots -- this post covers the design philosophy and practical workflow patterns behind the approach.
Claude Octopus is a Claude Code plugin that simultaneously calls Codex, Gemini, Copilot, Qwen, Ollama, Perplexity, OpenRouter, and Claude to review the same code, using a 75% consensus threshold to catch single-model blind spots. It ships with 32 personas, 48 /octo:* slash commands, 51 skills, and a Dark Factory fully autonomous spec-to-code pipeline.
LLM Council is a local Web App Andrej Karpathy built over a weekend. It sends one question to multiple LLMs simultaneously, has them anonymously peer-review each other, and then a Chairman model synthesizes a final answer. Positioned as a small tool for comparing models while studying — 99% vibe coded with no plans for long-term maintenance — but the architecture itself is a minimal ensemble LLM implementation worth studying.
oh-my-openagent (OmO) transforms OpenCode from a single-LLM tool into a multi-model agent team — Opus as the workhorse, GPT-5.2 as the architect, Gemini for frontend, Sonnet for documentation lookup — all triggered to run in parallel with a single ultrawork keyword. With 48K stars, it is the earliest project in the UltraWorkers ecosystem to establish the multi-agent coding pattern.
