OpenAI Releases Plugin to Run Codex from Inside Claude Code
OpenAI published an open-source plugin that lets developers use Codex directly within Anthropic's Claude Code CLI.
OpenAI has released codex-plugin-cc, an open-source plugin that allows developers to invoke OpenAI's Codex agent from within Anthropic's Claude Code command-line tool. The plugin enables users to delegate code review and other development tasks to Codex without leaving their Claude Code workflow.
The release is notable for what it signals about the competitive landscape in AI-powered development tools. Rather than treating rival platforms as walled gardens, OpenAI is building a bridge into Anthropic's developer environment — a move that could expand Codex's reach among the growing base of Claude Code users. For developers, it means more flexibility to mix and match AI coding agents based on the task at hand, using Claude Code as the orchestration layer while tapping Codex for specific jobs like code review. The plugin follows a pattern emerging across the AI tooling ecosystem where interoperability, rather than lock-in, is becoming a competitive strategy.
