Effects and persistence

Hands the current session to a supported Codex app.

/app is an officially documented command for handing the current CLI thread into Codex Desktop. Use it when a task started in the terminal needs the desktop app's review, diff, terminal, thread, or worktree surfaces.

Changes

  • /app can hand off the current CLI thread into Codex Desktop on macOS and native Windows.
  • Windows workspace launches can open directly into Desktop instead of stopping at a manual prompt.
  • The command was first release-tracked in the 0.138.0 changelog and was confirmed in the official slash-command table on 2026-08-03.

Cautions

  • Do not confuse /app with /apps: /app switches interface, while /apps inserts connector mentions.
  • Handoff behavior depends on local app installation, OS support, workspace trust, and sign-in state.
  • After handoff, re-check /status, /permissions, and /diff before high-risk edits.
