  • Remove resurrected /collab slash command (#22535)
    ## Summary
    `/collab` was intentionally removed in
    [#12012](https://github.com/openai/codex/pull/12012), but the
    TUI/app-server migration accidentally brought that slash-command path
    back. This restores the earlier product decision so the TUI no longer
    advertises or dispatches `/collab`. This command was redundant because
    it did the same thing as `/plan` but in a less-intuitive way.
    
    ## What Changed
    - Remove `SlashCommand::Collab` from the TUI slash-command surface.
    - Delete the picker and app-event plumbing that only existed to service
    `/collab`.
    - Remove obsolete TUI test coverage for the deleted picker flow.
  • feat(tui): add ambient terminal pets (#21206)
    ## Why
    
    The Codex App has animated pets, but the TUI had no equivalent ambient
    companion surface. This brings that experience into terminal Codex while
    keeping the main chat flow usable: the pet should feel present, but it
    cannot cover transcript text, composer input, approvals, or picker
    content.
    
    The feature also needs to be terminal-aware. Different terminals support
    different image protocols, tmux can interfere with image rendering, and
    some users will want pets disabled entirely or anchored differently
    depending on their layout.

    ## What Changed
    
    - Add a TUI ambient pet renderer in `codex-rs/tui/src/pets/`.
    - Port the app-style pet animation states so the sprite changes with
    task status, waiting-for-input states, review/ready states, and
    failures.
    - Add `/pets` selection UI with a preview pane, loading state, built-in
    pet choices, and a first-row `Disable terminal pets` option.
    - Download built-in pet spritesheets on demand from the same public CDN
    path already used by Android, under
    `https://persistent.oaistatic.com/codex/pets/v1/...`, and cache them
    locally under `~/.codex/cache/tui-pets/`.
    - Keep custom pets local.
    - Add config support for pet selection, disabling pets, and choosing
    whether the pet follows the composer bottom or anchors to the terminal
    bottom.
    - Reserve layout space around the pet so transcript wrapping, live
    responses, and composer input do not render underneath the sprite.
    - Gate image rendering by terminal capability, disable image pets under
    tmux, and support both Kitty Graphics and SIXEL terminals.
    - Add redraw cleanup for terminal image artifacts, including sixel cell
    clearing.
    
    ## Current Scope
    
    - This is an initial TUI version of ambient pets, not full App parity.
    - It focuses on ambient sprite rendering, `/pets` selection, custom
    pets, terminal capability gating, and on-demand CDN-backed built-in
    assets.
    - The ambient text overlay is currently disabled, so the TUI renders the
    pet sprite without extra status text beside it.
    
    ## How to Test
    
    1. Start Codex TUI in a terminal with image support.
    2. Run `/pets`.
    3. Confirm the picker shows built-in pets plus custom pets, and the
    first item is `Disable terminal pets`.
    4. On a fresh `~/.codex/cache/tui-pets/`, move onto a built-in pet and
    confirm the first preview downloads the spritesheet from the shared
    Codex pets CDN and renders successfully.
    5. Move through the pet list and confirm subsequent built-in previews
    use the local cache.
    6. Select a pet, then send and receive messages. Confirm transcript and
    composer text wrap before the pet instead of rendering underneath the
    sprite.
    7. Change the pet anchor setting and confirm the pet can either follow
    the composer bottom or sit at the terminal bottom.
    8. Return to `/pets`, choose `Disable terminal pets`, and confirm the
    sprite disappears cleanly.
    
    Targeted tests:
    - `cargo test -p codex-tui ambient_pet_`
    - `cargo test -p codex-tui
    resize_reflow_wraps_transcript_early_when_pet_is_enabled`
    - `cargo insta pending-snapshots`
  • [codex] Generalize service tier slash commands (#21745)
    ## Why
    
    `/fast` was wired as a one-off slash command even though model metadata
    now exposes service tiers as catalog data. That meant adding another
    tier, such as a slower/cheaper tier, would require more hardcoded TUI
    plumbing instead of letting the model catalog drive the available
    commands.
    
    This change makes service-tier commands data-driven: each advertised
    `service_tiers` entry becomes a `/name` command using the catalog
    description, while the request path sends the tier `id` only when the
    selected model supports it.
    
    ## What Changed
    
    - Removed the hardcoded `/fast` slash-command variant and introduced
    dynamic service-tier command items in the composer and command popup.
    - Added toggle behavior for service-tier commands: invoking `/name`
    selects that tier, and invoking it again clears the selection.
    - Preserved the existing Fast-mode keybinding/status affordances by
    resolving the current model tier whose name is `fast`, while still
    sending the tier request value such as `priority`.
    - Persisted service-tier selections as raw request strings so non-fast
    tiers can round-trip through config.
    - Updated the Bedrock catalog entry to advertise fast support through
    `service_tiers` with `id: "priority"` and `name: "fast"`.
    - Added defensive filtering in core so unsupported selected service
    tiers are omitted from `/responses` requests.
    
    ## Validation
    
    - Added/updated coverage for dynamic service-tier slash command lookup,
    popup descriptions, composer dispatch, TUI fast toggling, and
    unsupported-tier omission in core request construction.
    - Local tests were not run per request.

  • feat(tui): add raw scrollback mode (#20819)
    ## Why
    
    Granular copy is particularly difficult with the current output. Part of
    it was solved with the introduction of the `/copy` command but when you
    only need to copy parts of a response, you still encounter some issues:
    
    - When you copy a paragraph, the result is a sequence of separate lines
    instead of one correctly joined paragraph.
    - When a word wraps, part of it stays on the original line and the rest
    appears at the start of the next line.
    - When you copy a long command, extra line breaks are often inserted,
    and command arguments can be split across multiple lines.
    
    
    https://github.com/user-attachments/assets/0ef85c84-9363-4aad-b43a-15fce062a443
    
    ## Solution
    
    Now that we own the scrollback and we re-create it when we resize, we
    have the opportunity of toggling between the raw text and the rich text
    we see today.
    
    - Add TUI raw scrollback mode with `tui.raw_output_mode`, `/raw
    [on|off]`, and the configurable `tui.keymap.global.toggle_raw_output`
    action.
    - Render transcript cells through rich/raw-aware paths so raw mode
    preserves source text and lets the terminal soft-wrap selection-friendly
    output.
    - Bind raw-mode toggle to `alt-r` by default, with the keybinding path
    toggling silently while `/raw` continues to emit confirmation messages.
    
    ## Related Issues
    
    Likely addressed by raw mode:
    
    - #12200: clean copy for multiline and soft-wrapped output. Raw mode
    removes Codex-inserted wrapping/indentation and lets the terminal
    soft-wrap logical lines.
    - #9252: command suggestions gain unwanted leading spaces when copied.
    Raw mode renders transcript text without the rich-mode left
    padding/gutter.
    - #8258: prompt output is hard to copy because of leading indentation.
    Raw mode renders user/source-backed transcript text without that
    decorative indentation.
    
    Partially or conditionally addressed:
    
    - #2880: copy/export message as Markdown. Raw mode exposes raw Markdown
    for terminal selection, but this PR does not add a dedicated
    export/copy-message command.
    - #19820: mouse drag selection + copy in the TUI. Raw mode improves
    terminal-native selection of output/history text, but this PR does not
    implement in-TUI mouse selection, highlighting, auto-copy, or composer
    selection.
    - #18979: copied content is divided into two parts. This should improve
    cases caused by Codex-inserted wraps/padding in rendered output; if the
    report is about pasting into the composer/input path, that remains
    outside this PR.

  • tui: retire /approvals and rename /autoreview to /approve (#21034)
    ## Why
    
    The TUI currently exposes overlapping command names for the same
    permissions flow: `/permissions` and the older `/approvals` alias. It
    also uses `/autoreview` for the manual retry flow, even though the
    action users take there is approving one denied auto-review request.
    
    This change makes the command surface consistent with the hard rebrand:
    - `/permissions` is the only command for permission settings.
    - `/approve` is the command for approving a recent auto-review denial.
    
    ## What changed
    
    - Removed the legacy `/approvals` slash command and its dispatch path.
    - Kept `/permissions` as the single permissions command shown and
    accepted by the TUI.
    - Renamed the auto-review denial command from `/autoreview` to
    `/approve`.
    - Updated nearby comments so they refer to `/permissions` rather than
    the retired `/approvals` name.
    
    ## Verification
    
    - Updated the slash-command unit test to assert that `AutoReview` now
    renders and parses as `approve`.
  • feat(tui): add keymap debug inspector (#20794)
    ## Why
    
    We constantly get bug reports about keys not being recognized by Codex
    when the terminal is not handling the key press. Running `/keymap debug`
    or `/keymap` and going to the Debug tab, we can allow the user to either
    understand that the key being pressed is not being recognized or to
    check what it's being recognized as and report or reassign that key.

  • Add /ide context support to the TUI (#20294)
    ## Why
    
    Users have asked for a `/ide` command in the TUI so Codex can use the
    active IDE session for live context such as the current file, open tabs,
    and selected ranges. We already support a similar feature in the Codex
    desktop app, so bringing it to the TUI makes sense.
    
    One subtle compatibility constraint is that the injected prompt wrapper
    and transcript stripping should match the desktop app and IDE extension.
    By using the same `## My request for Codex:` delimiter and hiding the
    injected context from transcript rendering the same way, threads created
    in the TUI render correctly in desktop and IDE surfaces, and threads
    created there replay correctly in the TUI, even when IDE context was
    included.
    
    Addresses https://github.com/openai/codex/issues/13834.
    
    ## What changed
    ### Summary
    This PR consists of four four pieces:
    1. An IPC client that uses a socket (Mac/Linux) or named pipe (Windows)
    to talk to the IDE Extension
    2. Logic that establishes the IPC connection and requests IDE context
    (open files, selection) on demand
    3. Logic that injects this context into the user prompt (using the same
    technique as the desktop app) and hides the added context when rendering
    the prompt in the TUI transcript
    4. A new slash command for enabling/disabling this mode and text within
    the footer to indicate when it's enabled
    
    ### Details
    - Added `/ide [on|off|status]` to the TUI, with bare `/ide` toggling IDE
    context on or off.
    - Added a Rust IDE context client that connects to the local Codex IDE
    IPC route as a client and requests context from the IDE extension flow.
    - Injected IDE context using the same prompt delimiter and
    transcript-stripping convention as the desktop app and IDE extension so
    shared threads render consistently across surfaces.
    - Added an `IDE context` status-line indicator while the feature is
    active and cleared it when enabling or fetching context fails.
    - Added handling for multiple selection ranges, oversized selections,
    interleaved IPC messages, and transient reconnect timing after quick
    toggles.
    
    ## Verification
    
    Did extensive manual testing in addition to running automated unit and
    regression tests.
    
    To test:
    
    - Launch VS Code (or Cursor) with the IDE extension.
    - Open one or more files in the IDE and select a range of text within
    one of them.
    - Start the TUI.
    - Ask the agent which files you have open in your IDE, and it should say
    that it does not know.
    - Enable `/ide` mode; note that `IDE context` appears in the lower
    right.
    - Ask the agent what files you have open in your IDE and what text is
    selected.
  • [codex] Remove unused event messages (#20511)
    ## Why
    
    Several legacy `EventMsg` variants were still emitted or mapped even
    though clients either ignored them or had moved to item/lifecycle
    events. `Op::Undo` had also degraded to an unavailable shim, so this
    removes that dead task path instead of preserving a command that cannot
    do useful work.
    
    `McpStartupComplete`, `WebSearchBegin`, and `ImageGenerationBegin` are
    intentionally kept because useful consumers still depend on them: MCP
    startup completion drives readiness behavior, and the begin events let
    app-server/core consumers surface in-progress web-search and
    image-generation items before the final payload arrives.
    
    ## What Changed
    
    - Removed weak legacy event variants and payloads from `codex-protocol`,
    including legacy agent deltas, background events, and undo lifecycle
    events.
    - Kept/restored `EventMsg::McpStartupComplete`,
    `EventMsg::WebSearchBegin`, and `EventMsg::ImageGenerationBegin` with
    serializer and emission coverage.
    - Updated core, rollout, MCP server, app-server thread history,
    review/delegate filtering, and tests to rely on the useful replacement
    events that remain.
    - Removed `Op::Undo`, `UndoTask`, the undo test module, and stale TUI
    slash-command comments.
    - Stopped agent job/background progress and compaction retry notices
    from emitting `BackgroundEvent` payloads.
    
    ## Verification
    
    - `cargo check -p codex-protocol -p codex-app-server-protocol -p
    codex-core -p codex-rollout -p codex-rollout-trace -p codex-mcp-server`
    - `cargo test -p codex-protocol -p codex-app-server-protocol -p
    codex-rollout -p codex-rollout-trace -p codex-mcp-server`
    - `cargo test -p codex-core --test all suite::items`
    - `just fix -p codex-protocol -p codex-app-server-protocol -p codex-core
    -p codex-rollout -p codex-rollout-trace -p codex-mcp-server`
    - Earlier coverage on this PR also included `codex-mcp`, `codex-tui`,
    core library tests, MCP/plugin/delegate/review/agent job tests, and MCP
    startup TUI tests.
  • feat(tui): add vim composer mode (#18595)
    ## Why
    
    Codex now has configurable TUI keymaps, but the composer still behaves
    like a plain text field. Users who prefer modal editing need a way to
    keep Vim muscle memory while drafting prompts, and the keymap picker
    needs to expose Vim-specific actions if those bindings are configurable
    instead of hardcoded.
    
    ## What Changed
    
    - Adds composer Vim mode with insert/normal state, common normal-mode
    movement and editing commands, `d`/`y` operator-pending flows, and
    mode-aware footer and cursor indicators.
    - Adds `/vim`, an optional global `toggle_vim_mode` binding, and
    `tui.vim_mode_default` so Vim mode can be toggled per session or enabled
    as the default composer state.
    - Extends runtime and config keymaps with `vim_normal` and
    `vim_operator` contexts, exposes those contexts in `/keymap`, refreshes
    the config schema, and validates Vim bindings separately.
    - Integrates Vim normal mode with existing composer behavior: `/` opens
    slash command entry, `!` enters shell mode, `j`/`k` navigate history at
    history boundaries, successful submissions reset back to normal mode,
    and paste burst handling remains insert-mode only.
    - Teaches the TUI render path to apply and restore cursor style so Vim
    insert mode can use a bar cursor without leaving the terminal in that
    state after exit.
    
    ## Validation
    
    - `cargo test -p codex-tui keymap -- --nocapture` on the keymap/Vim
    coverage
    - `cargo insta pending-snapshots`
    
    ## Docs
    
    This introduces user-facing `/vim`, `tui.vim_mode_default`, and Vim
    keymap contexts under `tui.keymap`, so the public CLI configuration and
    slash-command docs should be updated before the feature ships.
  • Add /hooks browser for lifecycle hooks (#19882)
    ## Why
    
    `hooks/list` and `hooks/config/write` give us read/write access to hooks
    and their state. This hooks up the TUI as a client so users can inspect
    and manage that state directly.
    
    ## What
    
    - add a two-page `/hooks` browser in the TUI: an event overview with
    installed/active counts, followed by a per-event handler page with
    toggle controls and detail rendering
    - thread managed-state metadata through hook discovery and `hooks/list`
    so the UI can label admin-managed hooks and suppress toggles for them
    - persist hook toggles through the existing config-write path and add
    snapshot coverage for the event list, handler list, managed-hook, and
    empty states
    
    ## Stack
    
    1. openai/codex#19705
    2. openai/codex#19778
    3. openai/codex#19840
    4. This PR - openai/codex#19882
    
    ## Reviewer Notes
    
    - Main UI logic is in
    `codex-rs/tui/src/bottom_pane/hooks_browser_view.rs`; most of the diff
    is the new view plus its snapshot coverage
    - Request / write plumbing for opening the browser and persisting
    toggles is in `codex-rs/tui/src/app/background_requests.rs` and
    `codex-rs/tui/src/chatwidget/hooks.rs`
    - Outside the TUI, the only behavioral change in this PR is threading
    `is_managed` through hook discovery and `hooks/list` so managed hooks
    render as non-toggleable
    - The `codex-rs/tui/src/status/snapshots/` churn is unrelated merge
    fallout from the stacked base branch's newer permission-label rendering

  • feat(tui): add configurable keymap support (#18593)
    ## Why
    
    The TUI currently handles keyboard shortcuts as hard-coded event matches
    spread across app, composer, pager, list, approval, and navigation code.
    That makes shortcuts hard to customize, makes displayed hints easy to
    drift from actual behavior, and makes future keymap work riskier because
    there is no central action inventory.
    
    This PR adds the foundation for configurable, action-based keymaps
    without adding the interactive remapping UI yet. Onboarding
    intentionally stays on fixed startup shortcuts because users cannot
    reasonably configure keymaps before completing onboarding.
    
    This is PR1 in the keymap stack:
    
    - PR1: #18593: configurable keymap foundation
    - PR2: #18594: `/keymap` picker and guided remapping UI
    - PR3: #18595: Vim composer mode and the remap option
    
    ## Design Notes
    
    The new model resolves named actions into concrete runtime bindings once
    from config, then passes those bindings to the UI surfaces that handle
    input or render shortcut hints.
    
    The main concepts are:
    
    - **Context**: a scope where an action is active, such as `global`,
    `chat`, `composer`, `editor`, `pager`, `list`, or `approval`.
    - **Action**: a named operation inside a context, such as
    `global.open_transcript`, `composer.submit`, or `pager.close`.
    - **Binding**: one or more single-key shortcuts assigned to an action,
    written as config strings such as `ctrl-t`, `alt-backspace`, or
    `page-down`. Multi-step sequences such as `ctrl-x ctrl-s`, `g g`, or
    leader-key flows are not part of this PR.
    - **Resolution order**: context-specific config wins first, supported
    global fallbacks come next, and built-in defaults fill in anything
    unset.
    - **Explicit unbinding**: an empty array removes an action binding in
    that scope and does not fall through to a fallback binding.
    - **Conflict validation**: a resolved keymap rejects duplicate active
    bindings inside the same scope so one keypress cannot dispatch two
    actions.
    
    ## What Changed
    
    - Added `TuiKeymap` config support under `[tui.keymap]`, including typed
    contexts/actions, key alias normalization, generated schema coverage,
    and user-facing config errors.
    - Added `RuntimeKeymap` resolution in `codex-rs/tui/src/keymap.rs`,
    including fallback precedence, built-in defaults, explicit unbinding,
    and per-context conflict validation.
    - Rewired existing TUI handlers to consume resolved keymap actions
    instead of directly matching hard-coded keys in each component.
    - Updated key hint rendering and footer/pager/list surfaces so displayed
    shortcuts follow the resolved keymap.
    - Kept onboarding shortcuts fixed in
    `codex-rs/tui/src/onboarding/keys.rs` instead of exposing them through
    `[tui.keymap]`.
    
    ## Validation
    
    The branch includes focused coverage for config parsing, key
    normalization, runtime fallback resolution, explicit unbinding,

  • Allow /statusline and /title slash commands during active turns (#19917)
    - Marks `/title` and `/statusline` as available during active tasks.
    - Extends the existing slash-command availability test coverage to
    include these commands alongside `/goal`.
  • Add /auto-review-denials retry approval flow (#19058)
    ## Why
    
    Auto-review can deny an action that the user later decides they want to
    retry. Today there is no TUI surface for selecting a recent denial and
    sending explicit approval context back into the session, so users have
    to restate intent manually and the retry can be reviewed without the
    original denied action context.
    
    This adds a narrow TUI-driven path for approving a recent denied action
    while still keeping the retry inside the normal auto-review flow.
    
    ## What Changed
    
    - Added `/auto-review-denials` to open a picker of recent denied
    auto-review actions.
    - Added a small in-memory TUI store for the 10 most recent denied
    auto-review events.
    - Selecting a denial sends the structured denied event back through the
    existing core/app-server op path.
    - Core now injects a developer message containing the approved action
    JSON rather than the full assessment event.
    - Auto-review transcript collection now preserves this specific approval
    developer message so follow-up review sessions can see the user approval
    context.
    - Added TUI snapshot/unit coverage for the picker and approval dispatch
    path.
    - Added core coverage for retaining the approval developer message in
    the auto-review transcript.
    
    ## Verification
    
    - `cargo test -p codex-core
    collect_guardian_transcript_entries_keeps_manual_approval_developer_message`
    - `cargo test -p codex-tui auto_review_denials`
    - `cargo test -p codex-tui
    approving_recent_denial_emits_structured_core_op_once`
    
    ## Notes
    
    This intentionally keeps retries going through auto-review. The approval
    signal is context for the exact previously denied action, not a blanket
    bypass for similar future actions.
  • Add goal TUI UX (5 / 5) (#18077)
    Adds the TUI user experience for goals on top of the core runtime from
    PR 4.
    
    ## Why
    
    Users need a direct TUI control surface for long-running goals. The UI
    should make the current goal visible, support common goal actions
    without waiting for a model turn, and avoid confusing end-of-turn
    notifications while an active goal is immediately continuing.
    
    ## What changed
    
    - Added `/goal` summary rendering for the current goal, including
    active, paused, budget-limited, and complete states.
    - Added `/goal <objective>` creation/replacement through the app-server
    goal API rather than a model prompt.
    - Added `/goal clear`, `/goal pause`, and `/goal unpause` command
    variants.
    - Added a confirmation menu when the user enters a new goal while
    another goal already exists.
    - Updated `/goal` help and summary tip text so it reflects the supported
    command variants without advertising slash-command token budgets.
    - Added footer/statusline goal indicators, including elapsed time and
    token budget display when a budget exists from API/tool-created goals.
    - Consumes goal updated/cleared notifications so the TUI stays in sync
    with external app-server changes.
    - Suppresses end-of-turn desktop notifications only when a goal is still
    active and follow-up work is expected.
    - Preserves slash-command history behavior and avoids leaking queued
    `/goal` state into unrelated submissions.
    
    ## Verification
    
    - Added TUI unit and snapshot coverage for goal command availability,
    summary rendering, control commands, replacement menu behavior,
    status/footer display, notification handling, and command history.
  • Add verbose diagnostics for /mcp (#18610)
    Fixes #18539.
    
    ## Summary
    The recent `/mcp` performance work kept the default command fast by
    avoiding resource and resource-template inventory probes, but it also
    removed useful diagnostics for users trying to confirm MCP server state.
    
    This keeps bare `/mcp` on the fast tools/auth path and adds `/mcp
    verbose` for the slower diagnostic view. Verbose mode requests full MCP
    server status from the app-server and restores status, resources, and
    resource templates in the TUI output.
    
    ## Testing
    In addition to running automation, I manually tested the feature to
    confirm that it works.
  • Soften Fast mode plan usage copy (#18601)
    Fast mode TUI copy currently names a specific plan-usage multiplier in
    two lightweight promo/help surfaces. This swaps that exact multiplier
    language for the broader increased plan usage wording we use elsewhere.
    
    There are no behavior changes here; the slash command and startup tip
    still point users at the same Fast mode flow.
  • Add /side conversations (#18190)
    The TUI supports long-running turns and agent threads, but quick side
    questions have required interrupting the main flow or manually
    forking/navigating threads. This PR adds a guarded `/side` flow so users
    can ask brief side-conversation questions in an ephemeral fork while
    keeping the primary thread focused. This also helps address the feature
    request in #18125.
    
    The implementation creates one side conversation at a time, lets `/side`
    open either an empty side thread or immediately submit `/side
    <question>`, and returns to the parent with Esc or Ctrl+C. Side
    conversations get hidden developer guardrails that treat inherited
    history as reference-only and steer the model away from workspace
    mutations unless explicitly requested in the side conversation.
    
    The TUI hides most slash commands while side mode is active, leaving
    only `/copy`, `/diff`, `/mention`, and `/status` available there.
  • feat: memories menu (#17632)
    Add menu that:
    1. If memories feature is not enabled, propose to enable it
    2. Let you choose if you want to generate memories and to use memories
  • feat(tui): Ctrl+O copy hotkey and harden copy-as-markdown behavior (#16966)
    ## TL;DR
    
    - New `Ctrl+O` shortcut on top of the existing `/copy` command, allowing
    users to copy the latest agent response without having to cancel a plan
    or type `/copy`
    - Copy server clipboard to the client over SSH (OSC 52)
    - Fixes linux copy behavior: a clipboard handle has to be kept alive
    while the paste happens for the contents to be preserved
    - Uses arboard as primary mechanism on Windows, falling back to
    PowerShell copy clipboard function
    - Works with resumes, rolling back during a session, etc.
    
    Tested on macOS, Linux/X11, Windows WSL2, Windows cmd.exe, Windows
    PowerShell, Windows VSCode PowerShell, Windows VSCode WSL2, SSH (macOS
    -> macOS).
    
    ## Problem
    
    The TUI's `/copy` command was fragile. It relied on a single
    `last_copyable_output` field that was bluntly cleared on every rollback
    and thread reconfiguration, making copied content unavailable after
    common operations like backtracking. It also had no keyboard shortcut,
    requiring users to type `/copy` each time. The previous clipboard
    backend mixed platform selection policy with low-level I/O in a way that
    was hard to test, and it did not keep the Linux clipboard owner alive —
    meaning pasted content could vanish once the process that wrote it
    dropped its `arboard::Clipboard`.
    
    This addresses the text-copy failure modes reported in #12836, #15452,
    and #15663: native Linux clipboard access failing in remote or
    unreachable-display environments, copy state going blank even after
    visible assistant output, and local Linux X11 reporting success while
    leaving the clipboard empty.
    
    ## Shortcut rationale
    
    The copy hotkey is `Ctrl+O` rather than `Alt+C` because Alt/Option
    combinations are not delivered consistently by macOS terminal emulators.
    Terminal.app and iTerm2 can treat Option as text input or as a
    configurable Meta/Esc prefix, and Option+C may be consumed or
    transformed before the TUI sees an `Alt+C` key event. `Ctrl+O` is a
    stable control-key chord in Terminal.app, iTerm2, SSH, and the existing
    cross-platform terminal stack.
    
    ## Mental model
    
    Agent responses are now tracked as a bounded, ordinal-indexed history
    (`agent_turn_markdowns: Vec<AgentTurnMarkdown>`) rather than a single
    nullable string. Each completed agent turn appends an entry keyed by its
    ordinal (the number of user turns seen so far). Rollbacks pop entries
    whose ordinal exceeds the remaining turn count, then use the visible
    transcript cells as a best-effort fallback if the ordinal history no
    longer has a surviving entry. This means `/copy` and `Ctrl+O` reflect
    the most recent surviving agent response after a backtrack, instead of
    going blank.
    
    The clipboard backend was rewritten as `clipboard_copy.rs` with a
    strategy-injection design: `copy_to_clipboard_with` accepts closures for
    the OSC 52, arboard, and WSL PowerShell paths, making the selection
    logic fully unit-testable without touching real clipboards. On Linux,
    the `Clipboard` handle is returned as a `ClipboardLease` stored on
    `ChatWidget`, keeping X11/Wayland clipboard ownership alive for the
    lifetime of the TUI. When native copy fails under WSL, the backend now
    tries the Windows clipboard through PowerShell before falling back to
    OSC 52.
    
    ## Non-goals
    
    - This change does not introduce rich-text (HTML) clipboard support; the
    copied content is raw markdown.
    - It does not add a paste-from-history picker or multi-entry clipboard
    ring.
    - WSL support remains a best-effort fallback, not a new configuration
    surface or guarantee for every terminal/host combination.
    
    ## Tradeoffs
    
    - **Bounded history (256 entries)**: `MAX_AGENT_COPY_HISTORY` caps
    memory. For sessions with thousands of turns this silently drops the
    oldest entries. The cap is generous enough for realistic sessions.
    - **`saw_copy_source_this_turn` flag**: Prevents double-recording when
    both `AgentMessage` and `TurnComplete.last_agent_message` fire for the
    same turn. The flag is reset on turn start and on turn complete,
    creating a narrow window where a race between the two events could
    theoretically skip recording. In practice the protocol delivers them
    sequentially.
    - **Transcript fallback on rollback**:
    `last_agent_markdown_from_transcript` walks the visible transcript cells
    to reconstruct plain text when the ordinal history has been fully
    truncated. This path uses `AgentMessageCell::plain_text()` which joins
    rendered spans, so it reconstructs display text rather than the original
    raw markdown. It keeps visible text copyable after rollback, but
    responses with markdown-specific syntax can diverge from the original
    source.
    - **Clipboard fallback ordering**: SSH still uses OSC 52 exclusively
    because native/PowerShell clipboard access would target the wrong
    machine. Local sessions try native clipboard first, then WSL PowerShell
    when running under WSL, then OSC 52. This adds one process-spawn
    fallback for WSL users but keeps the normal desktop and SSH paths
    simple.

    ## Tests
    
    - `clipboard_copy.rs`: Unit tests cover OSC 52 encoding roundtrip,

    PowerShell-to-OSC52 fallback, and all-error reporting via strategy
    injection.
    - `chatwidget/tests/slash_commands.rs`: Updated existing `/copy` tests
    to use `last_agent_markdown_text()` accessor. Added coverage for the
    Linux clipboard lease lifecycle, missing
    `TurnComplete.last_agent_message` fallback through completed assistant
    items, replayed legacy agent messages, stale-output prevention after
    rollback, and the `Ctrl+O` no-output hotkey path.
    - `app_backtrack.rs`: Added
    `agent_group_count_ignores_context_compacted_marker` verifying that
    info-event cells don't inflate the agent group count.

    Support `/resume 00000-0000-0000-00000000` from the TUI (equivalent for
    the name)
  • Rename tui_app_server to tui (#16104)
    This is a follow-up to https://github.com/openai/codex/pull/15922. That
    previous PR deleted the old `tui` directory and left the new
    `tui_app_server` directory in place. This PR renames `tui_app_server` to
    `tui` and fixes up all references.
  • Remove the legacy TUI split (#15922)
    This is the part 1 of 2 PRs that will delete the `tui` /
    `tui_app_server` split. This part simply deletes the existing `tui`
    directory and marks the `tui_app_server` feature flag as removed. I left
    the `tui_app_server` feature flag in place for now so its presence
    doesn't result in an error. It is simply ignored.
    
    Part 2 will rename the `tui_app_server` directory `tui`. I did this as
    two parts to reduce visible code churn.
  • Initial plugins TUI menu - list and read only. tui + tui_app_server (#15215)
    ### Preliminary /plugins TUI menu
    - Adds a preliminary /plugins menu flow in both tui and tui_app_server.
    - Fetches plugin list data asynchronously and shows loading/error/cached
    states.
      - Limits this first pass to the curated ChatGPT marketplace.
      - Shows available plugins with installed/status metadata.
    - Supports in-menu search over plugin display name, plugin id, plugin
    name, and marketplace label.
    - Opens a plugin detail view on selection, including summaries for
    Skills, Apps, and MCP Servers, with back navigation.
    
    ### Testing
      - Launch codex-cli with plugins enabled (`--enable plugins`).
      - Run /plugins and verify:
          - loading state appears first
          - plugin list is shown
          - search filters results
    - selecting a plugin opens detail view, with a list of
    skills/connectors/MCP servers for the plugin
          - back action returns to the list.
    - Verify disabled behavior by running /plugins without plugins enabled
    (shows “Plugins are disabled” message).
    - Launch with `--enable tui_app_server` (and plugins enabled) and repeat
    the same /plugins flow; behavior should match.
  • feat(tui): add /title terminal title configuration (#12334)
    ## Problem
    
    When multiple Codex sessions are open at once, terminal tabs and windows
    are hard to distinguish from each other. The existing status line only
    helps once the TUI is already focused, so it does not solve the "which
    tab is this?" problem.
    
    This PR adds a first-class `/title` command so the terminal window or
    tab title can carry a short, configurable summary of the current
    session.
    
    ## Screenshot
    
    <img width="849" height="320" alt="image"
    src="https://github.com/user-attachments/assets/8b112927-7890-45ed-bb1e-adf2f584663d"
    />
    
    ## Mental model
    
    `/statusline` and `/title` are separate status surfaces with different
    constraints. The status line is an in-app footer that can be denser and
    more detailed. The terminal title is external terminal metadata, so it
    needs short, stable segments that still make multiple sessions easy to
    tell apart.
    
    The `/title` configuration is an ordered list of compact items. By
    default it renders `spinner,project`, so active sessions show
    lightweight progress first while idle sessions still stay easy to
    disambiguate. Each configured item is omitted when its value is not
    currently available rather than forcing a placeholder.
    
    ## Non-goals
    
    This does not merge `/title` into `/statusline`, and it does not add an
    arbitrary free-form title string. The feature is intentionally limited
    to a small set of structured items so the title stays short and
    reviewable.
    
    This also does not attempt to restore whatever title the terminal or
    shell had before Codex started. When Codex clears the title, it clears
    the title Codex last wrote.
    
    ## Tradeoffs
    
    A separate `/title` command adds some conceptual overlap with
    `/statusline`, but it keeps title-specific constraints explicit instead
    of forcing the status line model to cover two different surfaces.
    
    Title refresh can happen frequently, so the implementation now shares
    parsing and git-branch orchestration between the status line and title
    paths, and caches the derived project-root name by cwd. That keeps the
    hot path cheap without introducing background polling.
    
    ## Architecture
    
    The TUI gets a new `/title` slash command and a dedicated picker UI for
    selecting and ordering terminal-title items. The chosen ids are
    persisted in `tui.terminal_title`, with `spinner` and `project` as the
    default when the config is unset. `status` remains available as a
    separate text item, so configurations like `spinner,status` render
    compact progress like `⠋ Working`.
    
    `ChatWidget` now refreshes both status surfaces through a shared
    `refresh_status_surfaces()` path. That shared path parses configured
    items once, warns on invalid ids once, synchronizes shared cached state
    such as git-branch lookup, then renders the footer status line and
    terminal title from the same snapshot.
    
    Low-level OSC title writes live in `codex-rs/tui/src/terminal_title.rs`,
    which owns the terminal write path and last-mile sanitization before
    emitting OSC 0.
    
    ## Security
    
    Terminal-title text is treated as untrusted display content before Codex
    emits it. The write path strips control characters, removes invisible
    and bidi formatting characters that can make the title visually
    misleading, normalizes whitespace, and caps the emitted length.

    ## Observability
    
    Unknown configured title item ids are warned about once instead of
    repeatedly spamming the transcript. Live preview applies immediately
    while the `/title` picker is open, and cancel rolls the in-memory title
    selection back to the pre-picker value.
    
    If terminal title writes fail, the TUI emits debug logs around set and
    clear attempts. The rendered status label intentionally collapses richer
    internal states into compact title text such as `Starting...`, `Ready`,
    `Thinking...`, `Working...`, `Waiting...`, and `Undoing...` when
    `status` is configured.
    
    ## Tests
    
    Ran:
    
    - `just fmt`
    - `cargo test -p codex-tui`
    
    At the moment, the red Windows `rust-ci` failures are due to existing
    `codex-core` `apply_patch_cli` stack-overflow tests that also reproduce
    on `main`. The `/title`-specific `codex-tui` suite is green.
  • Preserve background terminals on interrupt and rename cleanup command to /stop (#14602)
    ### Motivation
    - Interrupting a running turn (Ctrl+C / Esc) currently also terminates
    long‑running background shells, which is surprising for workflows like
    local dev servers or file watchers.
    - The existing cleanup command name was confusing; callers expect an
    explicit command to stop background terminals rather than a UI clear
    action.
    - Make background‑shell termination explicit and surface a clearer
    command name while preserving backward compatibility.
    
    ### Description
    - Renamed the background‑terminal cleanup slash command from `Clean`
    (`/clean`) to `Stop` (`/stop`) and kept `clean` as an alias in the
    command parsing/visibility layer, updated the user descriptions and
    command popup wiring accordingly.
    - Updated the unified‑exec footer text and snapshots to point to `/stop`
    (and trimmed corresponding snapshot output to match the new label).
    - Changed interrupt behavior so `Op::Interrupt` (Ctrl+C / Esc interrupt)
    no longer closes or clears tracked unified exec / background terminal
    processes in the TUI or core cleanup path; background shells are now
    preserved after an interrupt.
    - Updated protocol/docs to clarify that `turn/interrupt` (or
    `Op::Interrupt`) interrupts the active turn but does not terminate
    background terminals, and that `thread/backgroundTerminals/clean` is the
    explicit API to stop those shells.
    - Updated unit/integration tests and insta snapshots in the TUI and core
    unified‑exec suites to reflect the new semantics and command name.
    
    ### Testing
    - Ran formatting with `just fmt` in `codex-rs` (succeeded). 
    - Ran `cargo test -p codex-protocol` (succeeded). 
    - Attempted `cargo test -p codex-tui` but the build could not complete
    in this environment due to a native build dependency that requires
    `libcap` development headers (the `codex-linux-sandbox` vendored build
    step); install `libcap-dev` / make `libcap.pc` available in
    `PKG_CONFIG_PATH` to run the TUI test suite locally.
    - Updated and accepted the affected `insta` snapshots for the TUI
    changes so visual diffs reflect the new `/stop` wording and preserved
    interrupt behavior.

  • feat(tui): syntax highlighting via syntect with theme picker (#11447)
    ## Summary
    
    Adds syntax highlighting to the TUI for fenced code blocks in markdown
    responses and file diffs, plus a `/theme` command with live preview and
    persistent theme selection. Uses syntect (~250 grammars, 32 bundled
    themes, ~1 MB binary cost) — the same engine behind `bat`, `delta`, and
    `xi-editor`. Includes guardrails for large inputs, graceful fallback to
    plain text, and SSH-aware clipboard integration for the `/copy` command.

    />
    
    ## Problem
    
    Code blocks in the TUI (markdown responses and file diffs) render
    without syntax highlighting, making it hard to scan code at a glance.
    Users also have no way to pick a color theme that matches their terminal
    aesthetic.
    
    ## Mental model
    
    The highlighting system has three layers:
    
    1. **Syntax engine** (`render::highlight`) -- a thin wrapper around
    syntect + two-face. It owns a process-global `SyntaxSet` (~250 grammars)
    and a `RwLock<Theme>` that can be swapped at runtime. All public entry
    points accept `(code, lang)` and return ratatui `Span`/`Line` vectors or
    `None` when the language is unrecognized or the input exceeds safety
    guardrails.
    
    2. **Rendering consumers** -- `markdown_render` feeds fenced code blocks
    through the engine; `diff_render` highlights Add/Delete content as a
    whole file and Update hunks per-hunk (preserving parser state across
    hunk lines). Both callers fall back to plain unstyled text when the
    engine returns `None`.
    
    3. **Theme lifecycle** -- at startup the config's `tui.theme` is
    resolved to a syntect `Theme` via `set_theme_override`. At runtime the
    `/theme` picker calls `set_syntax_theme` to swap themes live; on cancel
    it restores the snapshot taken at open. On confirm it persists `[tui]
    theme = "..."` to config.toml.
    
    ## Non-goals
    
    - Inline diff highlighting (word-level change detection within a line).
    - Semantic / LSP-backed highlighting.
    - Theme authoring tooling; users supply standard `.tmTheme` files.
    
    ## Tradeoffs
    
    | Decision | Upside | Downside |
    | ------------------------------------------------ |
    ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
    |
    -----------------------------------------------------------------------------------------------------------------------
    |
    | syntect over tree-sitter / arborium | ~1 MB binary increase for ~250
    grammars + 32 themes; battle-tested crate powering widely-used tools
    (`bat`, `delta`, `xi-editor`). tree-sitter would add ~12 MB for 20-30
    languages or ~35 MB for full coverage. | Regex-based; less structurally
    accurate than tree-sitter for some languages (e.g. language injections
    like JS-in-HTML). |
    | Global `RwLock<Theme>` | Enables live `/theme` preview without
    threading Theme through every call site | Lock contention risk
    (mitigated: reads vastly outnumber writes, single UI thread) |
    | Skip background / italic / underline from themes | Terminal BG
    preserved, avoids ugly rendering on some themes | Themes that rely on
    these properties lose fidelity |
    | Guardrails: 512 KB / 10k lines | Prevents pathological stalls on huge
    diffs or pastes | Very large files render without color |
    
    ## Architecture
    
    ```
    config.toml  ─[tui.theme]─>  set_theme_override()  ─>  THEME (RwLock)
                                                                  │
                      ┌───────────────────────────────────────────┘
                      │
      markdown_render ─── highlight_code_to_lines(code, lang) ─> Vec<Line>
      diff_render     ─── highlight_code_to_styled_spans(code, lang) ─> Option<Vec<Vec<Span>>>
                      │
                      │   (None ⇒ plain text fallback)
                      │
      /theme picker   ─── set_syntax_theme(theme)    // live preview swap
                      ─── current_syntax_theme()      // snapshot for cancel
                      ─── resolve_theme_by_name(name) // lookup by kebab-case
    ```
    
    Key files:
    
    - `tui/src/render/highlight.rs` -- engine, theme management, guardrails
    - `tui/src/diff_render.rs` -- syntax-aware diff line wrapping
    - `tui/src/theme_picker.rs` -- `/theme` command builder
    - `tui/src/bottom_pane/list_selection_view.rs` -- side content panel,
    callbacks
    - `core/src/config/types.rs` -- `Tui::theme` field
    - `core/src/config/edit.rs` -- `syntax_theme_edit()` helper
    
    ## Observability
    
    - `tracing::warn` when a configured theme name cannot be resolved.
    - `Config::startup_warnings` surfaces the same message as a TUI banner.
    - `tracing::error` when persisting theme selection fails.
    
    ## Tests
    
    - Unit tests in `highlight.rs`: language coverage, fallback behavior,
    CRLF stripping, style conversion, guardrail enforcement, theme name
    mapping exhaustiveness.
    - Unit tests in `diff_render.rs`: snapshot gallery at multiple terminal
    sizes (80x24, 94x35, 120x40), syntax-highlighted wrapping, large-diff
    guardrail, rename-to-different-extension highlighting, parser state
    preservation across hunk lines.
    - Unit tests in `theme_picker.rs`: preview rendering (wide + narrow),
    dim overlay on deletions, subtitle truncation, cancel-restore, fallback
    for unavailable configured theme.
    - Unit tests in `list_selection_view.rs`: side layout geometry, stacked
    fallback, buffer clearing, cancel/selection-changed callbacks.
    - Integration test in `lib.rs`: theme warning uses the final
    (post-resume) config.
    
    ## Cargo Deny: Unmaintained Dependency Exceptions
    
    This PR adds two `cargo deny` advisory exceptions for transitive
    dependencies pulled in by `syntect v5.3.0`:
    
    | Advisory | Crate | Status |
    |----------|-------|--------|
    | RUSTSEC-2024-0320 | `yaml-rust` | Unmaintained (maintainer
    unreachable) |
    | RUSTSEC-2025-0141 | `bincode` | Unmaintained (development ceased;
    v1.3.3 considered complete) |
    
    **Why this is safe in our usage:**
    
    - Neither advisory describes a known security vulnerability. Both are
    "unmaintained" notices only.
    - `bincode` is used by syntect to deserialize pre-compiled syntax sets.
    Again, these are **static vendored artifacts** baked into the binary at
    build time. No user-supplied bincode data is ever deserialized. - Attack
    surface is zero for both crates; exploitation would require a
    supply-chain compromise of our own build artifacts.
    - These exceptions can be removed when syntect migrates to `yaml-rust2`
    and drops `bincode`, or when alternative crates are available upstream.
  • add a slash command to grant sandbox read access to inaccessible directories (#11512)
    There is an edge case where a directory is not readable by the sandbox.
    In practice, we've seen very little of it, but it can happen so this
    slash command unlocks users when it does.
    
    Future idea is to make this a tool that the agent knows about so it can
    be more integrated.

  • Nicer highlighting of slash commands, /plan accepts prompt args and pasted images (#10269)
    ## Summary
    - Make typed slash commands become text elements when the user hits
    space, including paste‑burst spaces.
    - Enable `/plan` to accept inline args and submit them in plan mode,
    mirroring `/review` behavior and blocking submission while a task is
    running.
    - Preserve text elements/attachments for slash commands that take args.
    
    <img width="1510" height="500" alt="image"
    src="https://github.com/user-attachments/assets/446024df-b69a-4249-85db-1a85110e07f1"
    />
    
    ## Changes
    - Add safe helper to insert element ranges in the textarea.
    - Extend command‑with‑args pipeline to carry text elements and reuse
    submission prep.
    - Update `/plan` dispatch to switch to plan mode then submit prompt +
    elements.
    - Document new composer behavior and add tests.
    
    ## Notes
    - `/plan` is blocked during active tasks (same as `/review`).
    - Slash‑command elementization recognizes built‑ins and `/prompts:`
    custom commands only.

  • Conversation naming (#8991)
    Session renaming:
    - `/rename my_session`
    - `/rename` without arg and passing an argument in `customViewPrompt`
    - AppExitInfo shows resume hint using the session name if set instead of
    uuid, defaults to uuid if not set
    - Names are stored in `CODEX_HOME/sessions.jsonl`
    
    Session resuming:
    - codex resume <name> lookup for `CODEX_HOME/sessions.jsonl` first entry
    matching the name and resumes the session

  • tui: add feature-gated /plan slash command to switch to Plan mode (#10103)
    ## Summary
    Adds a simple `/plan` slash command in the TUI that switches the active
    collaboration mode to Plan mode. The command is only available when the
    `collaboration_modes` feature is enabled.
    
    ## Changes
    - Add `plan_mask` helper in `codex-rs/tui/src/collaboration_modes.rs`
    - Add `SlashCommand::Plan` metadata in
    `codex-rs/tui/src/slash_command.rs`
    - Implement and hard-gate `/plan` dispatch in
    `codex-rs/tui/src/chatwidget.rs`
    - Hide `/plan` when collaboration modes are disabled in
    `codex-rs/tui/src/bottom_pane/slash_commands.rs`
    - Update command popup tests in
    `codex-rs/tui/src/bottom_pane/command_popup.rs`
    - Add a focused unit test for `/plan` in
    `codex-rs/tui/src/chatwidget/tests.rs`
    
    ## Behavior notes
    - `/plan` is now a no-op if `Feature::CollaborationModes` is disabled.
    - When enabled, `/plan` switches directly to Plan mode without opening
    the picker.
