Codex 0.140.0 just shipped a `/import` command that one-click migrates your Claude Code setup. OpenAI is done competing — they're extracting.

Codex CLI 0.140.0 dropped yesterday.

The headline feature isn't performance or a new model.

It's `/import` — a command that selectively pulls your Claude Code setup, project configuration, and recent chat history directly into Codex.

This is the first time a major agent vendor has built an explicit extraction tool for a competitor's users.

The mechanics are surgical: you run `/import`, Codex scans your Claude Code config directory, and you pick exactly which pieces to transfer. Project rules, AGENTS.md files, session context — all portable.

OpenAI also shipped managed Amazon Bedrock API-key authentication in the same release.

Enterprise teams can now use Bedrock-hosted models with encrypted local credential storage for both CLI and MCP OAuth flows.

The multi-agent subsystem got quieter but important upgrades: path-based v2 activity tracking, thread-scoped MCP server contributions, and a new `ThreadStore` API that makes session state queryable across agents.

Also: permanent session deletion with `codex delete` and `/usage` views for daily, weekly, and cumulative token burn.

If you're running Claude Code in production, audit your config directory now.

Your AGENTS.md files, project rules, and session metadata are now a migration target.

OpenAI is treating your configuration as a competitive surface — and they just built the pipeline to move it.

SIGNAL: The coding agent war just shifted from feature competition to active user extraction. Configuration portability is the new battleground.
