What is codex-gpt-plugin?

This repository is a plugin for Codex, the coding agent, that lets it place a call to a logged-in ChatGPT Pro session in a real browser window. The idea is that Codex is strong at doing the actual coding work, but for harder problems like architecture decisions, research, weighing tradeoffs, or tricky debugging strategy, it can be useful to bring in a second opinion. Instead of using an API key or handling passwords, the plugin drives an actual browser where a human is already logged in, attaches the current repository as context, sends a message, reads back the reply, and saves a record of the exchange. Conversations are organized into named rooms tied to a specific git repository, such as main, debug, critic, or scratch, so different projects and different lines of work stay separated. When useful, the plugin can also build a single file containing a summary of the repository's source code, checking first for anything that looks like a secret before it is shared, and only sending it after the user confirms. A dedicated Chrome browser profile stays signed in between calls, and a locking system makes sure that if multiple Codex agents try to use the plugin at the same time, they take turns instead of interfering with each other's browser session. Every call is logged with the exact prompt and response, a screenshot, and technical logs, so there is a clear record of what was asked and answered. Installing it involves running npm install inside a local copy of the repository, then registering it with Codex as a plugin. From there, a command line tool called chatgpt-pro handles logging in, sending prompts, checking status, and managing the different conversation rooms. The project emphasizes that automation never types passwords or solves login challenges on the user's behalf, and it only interacts with the page through text input, never through simulated mouse or keyboard control. No license file is mentioned in the README shown.
