Codex CLI 0.167 adds an agent command center and backend switching
OpenAI released Codex CLI 0.167.0 with a no-daemon agent command center, unread-result markers, connected-backend switching that preserves drafts, local-image previews, a Vertex AI setup path, optional system proxy use and expanded approval-time patch details.
Why it matters: The release makes parallel agent results and provider changes easier to inspect from the terminal while surfacing more context at approval time. It also adds new provider, image and proxy paths that change credentials, network routing and local-data exposure.
