OpenAI Codex CLI v0.138.0: Desktop Handoff, Structured Plugin Output, and Account Token Visibility
OpenAI
Version 0.138.0 (June 8, 2026) adds desktop handoff for the `/app` command on macOS and Windows, local image file path exposure to models for follow-up edits, enhanced reasoning effort selection with fallback shortcuts for terminals missing Alt bindings, account token usage visibility and v2 personal access token support, and structured JSON output for plugin automation (`codex plugin list --json`). TUI streaming optimizations eliminate blank spacing artifacts and workspace instruction loading is improved for remote and symlinked environments. An alpha v0.139.0 build was also cut on June 9.
Why it matters
Desktop handoff closes the loop between CLI and GUI workflows, while structured JSON plugin output enables automated tooling around Codex sessions. The release continues the fast cadence following the Codex CLI Rust rewrite.
