Enable Codex `/tui` fullscreen and spawn worktree sessions from the command center

Codex CLI 0.156.0 adds optional /tui fullscreen with transcript search, mouse selection, and right-click copy; default worktrees from the command center; /usage for tokens, plugins, and skills; voice on by default (F8, /voice settings). Drop deprecated personality settings.

Why this loop

rust-v0.156.0 changes how you run long Codex sessions. /tui is an optional fullscreen UI with transcript search, mouse selection, and right-click copying, so you can navigate history without scrolling a raw terminal. Worktree support is enabled by default; from the agent command center you can filter tasks by status and create worktree sessions, which keeps parallel agent work isolated. /usage surfaces account usage, token totals, and plugin and skill activity so spend and skill load are visible in-product. Voice conversations are on by default (F8 toggle, /voice settings, bundled Linux/Windows audio runtimes). friendly and pragmatic personality settings are deprecated and no longer select response styles, so configs that still set them silently do nothing. Failed or interrupted turns now preserve streamed answers and plans, and Plan mode is restored when you resume.

Proposed actions

  1. In Codex CLI, type /tui on your next launch to switch to the optional fullscreen UI, then use transcript search, mouse selection, and right-click copying.
  2. Open the agent command center, filter tasks by status, and create a worktree session (worktree support is now enabled by default).
  3. Run /usage after a session to open the analytics dashboard and review account usage, token totals, and plugin and skill activity.
  4. Press F8 to toggle voice conversations (enabled by default) and run /voice settings to pick a voice; Linux and Windows include bundled audio runtimes.
  5. Remove friendly and pragmatic from your Codex personality config—they no longer select response styles—then choose one of the six new terminal themes.
