OpenAI Codex CLI rust-v0.153.0

New Features

• Vim mode now supports undo with u and redo with Ctrl+R, preserving complete drafts including pasted content and attachments. (#41941, #42140)

• The plugin CLI can list, install, and remove plugins from remote marketplaces. (#42150)

• Set tui.auto_recap = false to disable automatic recaps while keeping manual /recap available. (#42101)

• TUI history shows complete patches, input sent to background terminals, and individual completed commands. (#41893, #42107)

• Plus and Team users receive an earlier warning when less than half of their allowance remains in an approximately five-hour usage window. (#42142)

Bug Fixes

• TUI sessions reconnect after an external app-server connection drops, preserving drafts and transcripts while keeping uncertain or queued submissions paused for review. (#41911, #41916, #41918)

• Full Access skips Guardian reviews for confirmation-only actions. User approval mode skips background Guardian scoring and prewarming, while sensitive-action checks and requests for user input retain their existing handling. (#42147, #42256)

• Guardian review history survives compaction, restarts, and user-created forks while respecting rollback boundaries and isolating subagent history. (#41879, #42065)

• Remembered MCP tool approvals are scoped to the selected app account, and relative MCP executable paths start more reliably on macOS. (#42133, #42117)

• Rollout compression includes shared histories, codex exec resume handles compressed rollouts when selecting by working directory, and thread forks work with symlinked session roots. (#42039, #42135)

Configuration and API Updates

• App-server thread metadata includes nullable model and reasoningEffort fields. Structured asynchronous questions are supported through request_user_input_async when enabled by the model catalog. (#42151, #42178)

• tui.disable_paste_burst replaces the top-level setting, which remains supported as a fallback. (#41976)

• Adds the disabled-by-default features.context_management.experimental_mode configuration. When enabled for eligible ChatGPT Plus, Pro, or Pro Lite sessions using the Codex backend, it activates token-budget context, history notes, and the new_context tool. API-key sessions, custom providers, and temporary structured threads remain excluded. (#42385)
