OpenAI Codex
On its YouTube channel, OpenAI released a video about Codex during a series of virtual "Build Hours" events.

OpenAI's goal is to make Codex the sole, universal agent for code generation. It is recommended to view Codex as a full-fledged team member or even delegate tasks to it, acting as an architect or manager.

Codex can operate in two main modes: locally and in the cloud. Both environments are integrated via a ChatGPT account and synchronized with GitHub repositories. Task delegation is available through the web interface and the ChatGPT mobile app (iOS), allowing users to "run tasks when inspiration strikes," even away from the workstation.

A new extension, compatible with VS Code, Cursor, and other VSC forks. Codex can automatically check pull requests on GitHub. This functionality is not limited to static analysis – the agent can run code, check logic, and validate changes.

It is recommended to organize repositories with smaller files. The presence of tests, linters, and formatters allows the agent to independently detect and correct errors. For complex tasks, it's better to generate detailed plans in Markdown (plan.md). Using an agents.md file to document architectural decisions helps Codex immediately understand what it's working with.
