OpenAI's official Twitter account just dropped a link to a Codex migration tool with a simple caption: "It's here." The promotional image reads "Fewer rate limits, fewer interruptions." No press release, no blog post — just a tweet, waving at Claude Code users.
The migration tool is built into the Codex desktop app. Open Settings, hit "Import other agent setup," and the tool scans your computer for existing AI coding assistant configurations. Here's what it can bring over:
- System instructions and behavioral rules
- Custom skills and quick commands
- Recent 30 days of chat history and projects
- MCP server (a protocol for connecting external tools) configurations
- Hooks (automated scripts) and sub-agent settings
For configurations that can't be auto-converted, Codex starts a separate conversation to walk you through manual adjustments. OpenAI warns that you should check permissions and authentication settings after migration — the two platforms' permission systems aren't compatible, so settings may not carry over directly.

This comes on the heels of a Chrome extension for Codex that lets the AI control your browser from background tabs. Meanwhile, Anthropic has been testing Orbit, a proactive AI assistant for Gmail, Slack, and GitHub.
