Setup: Connect Extension Directly in Codex

Install the Codex Chrome extension on any Chromium-based browser (Chrome, Brave, Edge) without manual Chrome Web Store steps. In the Codex app, navigate to favorite apps, select the Chrome extension option—which links to OpenAI's setup page—and add it. This grants Codex browser control permissions. A dedicated browser skill enhances efficiency for tasks like navigation and interaction. Once connected, Codex handles automation hands-free, clicking elements and filling forms based on natural language prompts.

Capabilities: Automate Web Workflows and UI Testing

Codex turns browsers into agent-controlled environments for complex tasks. Use prompts like "use your Chrome extension, go to this website, and post a question to the council: is a hot dog a sandwich?" to trigger actions: open tabs, click buttons (e.g., start new discussion), type queries, and submit. It operates independently—user hands-off—while providing status updates for confirmation (e.g., "yes" to proceed). This excels for UI testing, debugging live apps, or repetitive web ops, outperforming manual scripting by handling dynamic sites via vision and reasoning.

Real-World Test: Interacting with LLM Council Plus

In a demo, Codex queried a custom LLM Council Plus deployment—a fork of Andrej Karpathy's project supporting up to 8 models. The council featured DeepSeek V4 Flash, Granite 4.1 on Llama, and Gemini 3.1 as chairman. Codex navigated the site, initiated a debate on "hot dog as sandwich," routed the query, awaited peer-ranked responses (models anonymously score each other to reduce bias), and retrieved the verdict: "technically and legally no, though culinarily debated." This validates Codex for end-to-end agent-browser loops, settling AI debates autonomously. Repo: https://github.com/jacob-bd/llm-council-plus.
