TLDR: use new message phase field emitted by preamble-supported models
to determine whether an AgentMessage is mid-turn commentary. if so,
restore the status indicator afterwards to indicate the turn has not
completed.
### Problem
`commit_tick` hides the status indicator while streaming assistant text.
For preamble-capable models, that text can be commentary mid-turn, so
hiding was correct during streaming but restore timing mattered:
- restoring too aggressively caused jitter/flashing
- not restoring caused indicator to stay hidden before subsequent work
(tool calls, web search, etc.)
### Fix
- Add optional `phase` to `AgentMessageItem` and propagate it from
`ResponseItem::Message`
- Keep indicator hidden during streamed commit ticks, restore only when:
- assistant item completes as `phase=commentary`, and
- stream queues are idle + task is still running.
- Treat `phase=None` as final-answer behavior (no restore) to keep
existing behavior for non-preamble models
### Tests
Add/update tests for:
- no idle-tick restore without commentary completion
- commentary completion restoring status before tool begin
- snapshot coverage for preamble/status behavior

## What changed
- In `codex-rs/core/src/skills/injection.rs`, we now honor explicit
`UserInput::Skill { name, path }` first, then fall back to text mentions
only when safe.
- In `codex-rs/tui/src/bottom_pane/chat_composer.rs`, mention selection
is now token-bound (selected mention is tied to the specific inserted
`$token`), and we snapshot bindings at submit time so selection is not
lost.
- In `codex-rs/tui/src/chatwidget.rs` and
`codex-rs/tui/src/bottom_pane/mod.rs`, submit/queue paths now consume
the submit-time mention snapshot (instead of rereading cleared composer
state).
- In `codex-rs/tui/src/mention_codec.rs` and
`codex-rs/tui/src/bottom_pane/chat_composer_history.rs`, history now
round-trips mention targets so resume restores the same selected
duplicate.
- In `codex-rs/tui/src/bottom_pane/skill_popup.rs` and
`codex-rs/tui/src/bottom_pane/chat_composer.rs`, duplicate labels are
normalized to `[Repo]` / `[App]`, app rows no longer show `Connected -`,
and description space is a bit wider.

## Before vs now
- Before: selecting a duplicate could still submit the default/repo
match, and resume could lose which duplicate was originally selected.
- Now: the exact selected target (skill path or app id) is preserved
through submit, queue/restore, and resume.
## Manual test
1. Build and run this branch locally:
- `cd /Users/daniels/code/codex/codex-rs`
- `cargo build -p codex-cli --bin codex`
- `./target/debug/codex`
2. Open mention picker with `$` and pick a duplicate entry (not the
first one).
3. Confirm duplicate UI:
- repo duplicate rows show `[Repo]`
- app duplicate rows show `[App]`
- app description does **not** start with `Connected -`
4. Submit the prompt, then press Up to restore draft and submit again.
Expected: it keeps the same selected duplicate target.
5. Use `/resume` to reopen the session and send again.
Expected: restored mention still resolves to the same duplicate target.
## Summary
This PR fixes a UI/streaming race when nudged or steer-enabled messages
are queued during an active Plan stream.
Previously, `submit_user_message_with_mode` switched collaboration mode
immediately (via `set_collaboration_mask`) even when the message was
queued. If that happened mid-Plan stream, `active_mode_kind` could flip
away from Plan before the turn finished, causing subsequent
`on_plan_delta` updates to be ignored in the UI.
Now, mode switching is deferred until the queued message is actually
submitted.
## What changed
- Added a per-message deferred mode override on `UserMessage`:
- `collaboration_mode_override: Option<CollaborationModeMask>`
- Updated `submit_user_message_with_mode` to:
- create a `UserMessage` carrying the mode override
- queue or submit that message without mutating global mode immediately
- Updated `submit_user_message` to:
- apply `collaboration_mode_override` just before constructing/sending
`Op::UserTurn`
- Kept queueing condition scoped to active Plan stream rendering:
- queue only while plan output is actively streaming in TUI
(`plan_stream_controller.is_some()`)
## Why
This preserves Plan mode for the remainder of the in-flight Plan turn,
so streamed plan deltas continue rendering correctly, while still
ensuring the follow-up queued message is sent with the intended
collaboration mode.
## Behavior after this change
- If a nudged/steer submission happens while Plan output is actively
streaming:
- message is queued
- UI stays in Plan mode for the running turn
- once dequeued/submitted, mode override is applied and the message is
sent in the intended mode
- If no Plan stream is active:
- submission proceeds immediately and mode override is applied as before
## Tests
Added/updated coverage in `tui/src/chatwidget/tests.rs`:
- `submit_user_message_with_mode_queues_while_plan_stream_is_active`
- asserts mode remains Plan while queued
- asserts mode switches to Code when queued message is actually
submitted
- `submit_user_message_with_mode_submits_when_plan_stream_is_not_active`
- `steer_enter_queues_while_plan_stream_is_active`
- `steer_enter_submits_when_plan_stream_is_not_active`
Also updated existing `UserMessage { ... }` test fixtures to include the
new field.

Summary
- add a `required` flag for MCP servers everywhere config/CLI data is
touched so mandatory helpers can be round-tripped
- have `codex exec` and `codex app-server` thread start/resume fail fast
when required MCPs fail to initialize
This PR removes the inaccurate "Disable in /experimental." statement now
that the "personality" feature flag is no longer experimental.
This addresses #10850
So that the rest of the codebase (like TUI) don't need to be concerned
whether ChatGPT auth was handled by Codex itself or passed in via
app-server's external auth mode.
## Summary

Summary:
- read conversation summaries and cwd info from the state DB when
possible so we no longer rely on rollout files for metadata and avoid
extra I/O
- persist CLI version in thread metadata, surface it through summary
builders, and add the necessary DB migration hooks
- simplify thread listing by using enriched state DB data directly
rather than reading rollout heads
Testing:
- Not run (not requested)
Fixes#10661.
### Problem
On Windows, the sign-in menu can exit immediately if the OS-level input
buffer contains trailing characters (like the Enter key from running the
command).
### Solution
**Flush Input Buffer on Init**: Use FlushConsoleInputBuffer on Windows
(and cflush on Unix) in ui::init() to discard any input captured before
the TUI was ready.
Verified by @CodebyAmbrose in #10661.
## Summary
- add shared `ModeKind` helpers for display names, TUI visibility, and
`request_user_input` availability
- derive TUI mode filtering/labels from shared `ModeKind` metadata
instead of local hardcoded matches
- derive `request_user_input` availability text and unavailable error
mode names from shared mode metadata
- replace hardcoded known mode names in the Default collaboration-mode
template with `{{KNOWN_MODE_NAMES}}` and fill it from
`TUI_VISIBLE_COLLABORATION_MODES`
- add regression tests for mode metadata sync and placeholder
replacement
## Notes
- `cargo test -p codex-core` integration target (`tests/all`) still
shows pre-existing env-specific failures in this environment due missing
`test_stdio_server` binary resolution; core unit tests are green.

`phase` to avoid this class of error in a few hours.
commands parsed as unknown faced this issue
tested locally, added test for specific failure flow
## Problem
When a turn streamed a preamble line before any tool activity,
`ChatWidget` hid the status row while committing streamed lines and did
not restore it until a later event (commonly `ExecCommandBegin`). During
that idle gap, the UI looked finished even though the turn was still
active.
## Mental model
The bottom status row and transcript stream are separate progress
affordances:
- transcript stream shows committed output
- status row (spinner/shimmer + header) shows liveness of an active turn
While stream output is actively committing, hiding the status row is
acceptable to avoid redundant visual noise. Once stream controllers go
idle, an active turn must restore the status row immediately so liveness
remains visible across preamble-to-tool gaps.
## Non-goals
- No changes to streaming chunking policy or pacing.
- No changes to final completion behavior (status still hides when task
actually ends).
- No refactor of status lifecycle ownership between `ChatWidget` and
`BottomPane`.
## Tradeoffs
- We keep the existing behavior of hiding the status row during active
stream commits.
- We add explicit restoration on the idle boundary when the task is
still running.
- This introduces one extra status update on idle transitions, which is
small overhead but makes liveness semantics consistent.
## Architecture
`run_commit_tick_with_scope` in `chatwidget.rs` now documents and
enforces a two-phase contract:
1. For each committed streamed cell, hide status and append transcript
output.
2. If controllers are present and all idle, restore status iff task is
still running, preserving the current header.
This keeps status ownership in `ChatWidget` while relying on
`BottomPane` helpers:
- `hide_status_indicator()` during active stream commits
- `ensure_status_indicator()` +
`set_status_header(current_status_header)` at stream-idle boundary
Documentation pass additions:
- Clarified the function-level contract and lifecycle intent in
`run_commit_tick_with_scope`.
- Added an explicit regression snapshot test comment describing the
failing sequence.
## Observability
Signal that the fix is present:
- In the preamble-idle state, rendered output still includes `• Working
(… esc to interrupt)`.
- New snapshot:
`codex_tui__chatwidget__tests__preamble_keeps_working_status.snap`.
Debug path for future regressions:
- Start at `run_commit_tick_with_scope` for hide/restore transitions.
- Verify `bottom_pane.is_task_running()` at idle transition.
- Confirm `current_status_header` continuity when status is recreated.
- Use the new snapshot and targeted test sequence to reproduce
deterministic preamble-idle behavior.
## Tests
- Updated regression assertion:
- `streaming_final_answer_keeps_task_running_state` now expects status
widget to remain present while turn is running.
- Renamed/updated behavioral regression:
- `preamble_keeps_status_indicator_visible_until_exec_begin`.
- Added snapshot regression coverage:
- `preamble_keeps_working_status_snapshot`.
- Snapshot file:
`tui/src/chatwidget/snapshots/codex_tui__chatwidget__tests__preamble_keeps_working_status.snap`.
Commands run:
- `just fmt`
- `cargo test -p codex-tui
preamble_keeps_status_indicator_visible_until_exec_begin`
- `cargo test -p codex-tui preamble_keeps_working_status_snapshot`
## Risks / Inconsistencies
- Status visibility policy is still split across multiple event paths
(`commit tick`, `turn complete`, `exec begin`), so future regressions
can reintroduce ordering gaps.
- Restoration depends on `is_task_running()` correctness; if task
lifecycle flags drift, status behavior will drift too.
- Snapshot proves rendered state, not animation cadence; cadence still
relies on frame scheduling behavior elsewhere.
This PR fixes jitter in the TUI apps menu by making the description
column stable during rendering and height measurement.
Added a `stable_desc_col` option to
`SelectionViewParams`/`ListSelectionView`, introduced stable variants of
the shared row render/measure helpers in `selection_popup_common`, and
enabled the stable mode for the apps/connectors picker in `chatwidget`.
With these changes, only the apps/connectors picker uses this new
option, though it could be used elsewhere in the future.
Why: previously, the description column was computed from only currently
visible rows, so as you scrolled or filtered, the column could shift and
cause wrapping/height changes that looked jumpy. Computing it from all
rows in this popup keeps alignment and layout consistent as users scroll
through avaialble apps.

## Summary
This PR updates the `request_user_input` TUI overlay so `Esc` is
context-aware:
- When notes are visible for an option question, `Esc` now clears notes
and exits notes mode.
- When notes are not visible (normal option selection UI), `Esc` still
interrupts as before.
It also updates footer guidance text to match behavior.
## Changes
- Added a shared notes-clear path for option questions:
- `Tab` and `Esc` now both clear notes and return focus to options when
notes are visible.
- Updated footer hint text in notes-visible state:
- from: `tab to clear notes | ... | esc to interrupt`
- to: `tab or esc to clear notes | ...`
- Hid `esc to interrupt` hint while notes are visible for option
questions.
- Kept `esc to interrupt` visible and functional in normal
option-selection mode.
- Updated tests to assert the new `Esc` behavior in notes mode.
- Updated snapshot output for the notes-visible footer row.
- Updated docs in `docs/tui-request-user-input.md` to reflect
mode-specific `Esc` behavior.
## Summary
- preserve baseline streaming behavior (smooth mode still commits one
line per 50ms tick)
- extract adaptive chunking policy and commit-tick orchestration from
ChatWidget into `streaming/chunking.rs` and `streaming/commit_tick.rs`
- add hysteresis-based catch-up behavior with bounded batch draining to
reduce queue lag without bursty single-frame jumps
- document policy behavior, tuning guidance, and debug flow in rustdoc +
docs
## Testing
- just fmt
- cargo test -p codex-tui
## Summary
This PR simplifies collaboration modes to the visible set `default |
plan`, while preserving backward compatibility for older partners that
may still send legacy mode
names.
Specifically:
- Renames the old Code behavior to **Default**.
- Keeps **Plan** as-is.
- Removes **Custom** mode behavior (fallbacks now resolve to Default).
- Keeps `PairProgramming` and `Execute` internally for compatibility
plumbing, while removing them from schema/API and UI visibility.
- Adds legacy input aliasing so older clients can still send old mode
names.
## What Changed
1. Mode enum and compatibility
- `ModeKind` now uses `Plan` + `Default` as active/public modes.
- `ModeKind::Default` deserialization accepts legacy values:
- `code`
- `pair_programming`
- `execute`
- `custom`
- `PairProgramming` and `Execute` variants remain in code but are hidden
from protocol/schema generation.
- `Custom` variant is removed; previous custom fallbacks now map to
`Default`.
2. Collaboration presets and templates
- Built-in presets now return only:
- `Plan`
- `Default`
- Template rename:
- `core/templates/collaboration_mode/code.md` -> `default.md`
- `execute.md` and `pair_programming.md` remain on disk but are not
surfaced in visible preset lists.
3. TUI updates
- Updated user-facing naming and prompts from “Code” to “Default”.
- Updated mode-cycle and indicator behavior to reflect only visible
`Plan` and `Default`.
- Updated corresponding tests and snapshots.
4. request_user_input behavior
- `request_user_input` remains allowed only in `Plan` mode.
- Rejection messaging now consistently treats non-plan modes as
`Default`.
5. Schemas
- Regenerated config and app-server schemas.
- Public schema types now advertise mode values as:
- `plan`
- `default`
## Backward Compatibility Notes
- Incoming legacy mode names (`code`, `pair_programming`, `execute`,
`custom`) are accepted and coerced to `default`.
- Outgoing/public schema surfaces intentionally expose only `plan |
default`.
- This allows tolerant ingestion of older partner payloads while
standardizing new integrations on the reduced mode set.

###### Summary
- Add input_modalities to model metadata so clients can determine
supported input types.
- Gate image paste/attach in TUI when the selected model does not
support images.
- Block submits that include images for unsupported models and show a
clear warning.
- Propagate modality metadata through app-server protocol/model-list
responses.
- Update related tests/fixtures.
###### Rationale
- Models support different input modalities.
- Clients need an explicit capability signal to prevent unsupported
requests.
- Backward-compatible defaults preserve existing behavior when modality
metadata is absent.
###### Scope
- codex-rs/protocol, codex-rs/core, codex-rs/tui
- codex-rs/app-server-protocol, codex-rs/app-server
- Generated app-server types / schema fixtures
###### Trade-offs
- Default behavior assumes text + image when field is absent for
compatibility.
- Server-side validation remains the source of truth.
###### Follow-up
- Non-TUI clients should consume input_modalities to disable unsupported
attachments.
- Model catalogs should explicitly set input_modalities for text-only
models.
###### Testing
- cargo fmt --all
- cargo test -p codex-tui
- env -u GITHUB_APP_KEY cargo test -p codex-core --lib
- just write-app-server-schema
- cargo run -p codex-cli --bin codex -- app-server generate-ts --out
app-server-types
- test against local backend

This PR addresses #10395
When a user is asked to pick the trust level of a project, the code
currently reloads the config if they select "trusted". It doesn't reload
the config in the "untrusted" case but should. This causes the sandbox
mode to be reported incorrectly in `/status` during the first run (it's
displayed as `read-only` even though it acts as though it's
`workspace-write`).
We started working with MCP in Codex before
https://crates.io/crates/rmcp was mature, so we had our own crate for
MCP types that was generated from the MCP schema:
8b95d3e082/codex-rs/mcp-types/README.md
Now that `rmcp` is more mature, it makes more sense to use their MCP
types in Rust, as they handle details (like the `_meta` field) that our
custom version ignored. Though one advantage that our custom types had
is that our generated types implemented `JsonSchema` and `ts_rs::TS`,
whereas the types in `rmcp` do not. As such, part of the work of this PR
is leveraging the adapters between `rmcp` types and the serializable
types that are API for us (app server and MCP) introduced in #10356.
Note this PR results in a number of changes to
`codex-rs/app-server-protocol/schema`, which merit special attention
during review. We must ensure that these changes are still
backwards-compatible, which is possible because we have:
```diff
- export type CallToolResult = { content: Array<ContentBlock>, isError?: boolean, structuredContent?: JsonValue, };
+ export type CallToolResult = { content: Array<JsonValue>, structuredContent?: JsonValue, isError?: boolean, _meta?: JsonValue, };
```
so `ContentBlock` has been replaced with the more general `JsonValue`.
Note that `ContentBlock` was defined as:
```typescript
export type ContentBlock = TextContent | ImageContent | AudioContent | ResourceLink | EmbeddedResource;
```
so the deletion of those individual variants should not be a cause of
great concern.
Similarly, we have the following change in
`codex-rs/app-server-protocol/schema/typescript/Tool.ts`:
```
- export type Tool = { annotations?: ToolAnnotations, description?: string, inputSchema: ToolInputSchema, name: string, outputSchema?: ToolOutputSchema, title?: string, };
+ export type Tool = { name: string, title?: string, description?: string, inputSchema: JsonValue, outputSchema?: JsonValue, annotations?: JsonValue, icons?: Array<JsonValue>, _meta?: JsonValue, };
```
so:
- `annotations?: ToolAnnotations` ➡️ `JsonValue`
- `inputSchema: ToolInputSchema` ➡️ `JsonValue`
- `outputSchema?: ToolOutputSchema` ➡️ `JsonValue`
and two new fields: `icons?: Array<JsonValue>, _meta?: JsonValue`

## Summary
This PR improves the TUI experience for `request_user_input` by
rendering submitted question/answer sets directly in conversation
history with clear, structured formatting.
It also intentionally simplifies interrupt behavior for now: on `Esc` /
`Ctrl+C`, the questions overlay interrupts the turn without attempting
to submit partial answers.
<img width="1344" height="573" alt="Screenshot 2026-02-02 at 4 51 40 PM"
src="https://github.com/user-attachments/assets/ff752131-7060-44c1-9ded-af061969a533"
/>
## Scope
- TUI-only changes.
- No core/protocol/app-server behavior changes in this PR.
- Resume reconstruction of interrupted question sets is out of scope for
this PR.
## What Changed
- Added a new history cell: `RequestUserInputResultCell` in
`codex-rs/tui/src/history_cell.rs`.
- On normal `request_user_input` submission, TUI now inserts that
history cell immediately after sending `Op::UserInputAnswer`.
- Rendering includes a `Questions` header with `answered/total` count.
- Rendering shows each question as a bullet item.
- Rendering styles submitted answer lines in cyan.
- Rendering styles notes (for option questions) as `note:` lines in
cyan.
- Rendering styles freeform text (for no-option questions) as `answer:`
lines in cyan.
- Rendering dims only the `(unanswered)` suffix.
- Rendering can include an interrupted suffix and summary text when the
cell is marked interrupted.
- Rendering redacts secret questions as `••••••` instead of showing raw
values.
- Added `wrap_with_prefix(...)` in `history_cell.rs` for wrapped
prefixed lines.
- Added `split_request_user_input_answer(...)` in `history_cell.rs` for
decoding `"user_note: ..."` entries.
## Interrupt Behavior (Intentional for this PR)
- `Esc` / `Ctrl+C` in the questions overlay now performs `Op::Interrupt`
and exits the overlay.
- It does **not** submit partial/committed answers on interrupt.
- Added TODO comments in `request_user_input` overlay interrupt paths
indicating where interrupted partial result emission should be
reintroduced once core support is finalized.
- Queued `request_user_input` overlays are discarded on interrupt in the
current behavior.
## Tests Updated
- Updated/added overlay tests in
`codex-rs/tui/src/bottom_pane/request_user_input/mod.rs` to reflect
interrupt-only behavior.
- Added helper assertion for interrupt-only event expectation.
- Existing submission-path tests now validate history insertion behavior
and expected answer maps.
## Behavior Notes
- Completed question flows now produce a readable `Questions` block in
transcript history.
- Interrupted flows currently do not persist partial answers to
model-visible tool output.
## Follow-ups
- Reintroduce partial-answer-on-interrupt semantics once core can
persist/sequence interrupted `request_user_input` outputs safely.
- Optionally add replay/resume rendering for interrupted question sets
as a separate PR.

## Summary
This fixes a UX bug (https://github.com/openai/codex/issues/10442) where
the **"Implement this plan?"** prompt could reappear after switching
agents with `/agent` and then switching back to the original agent
during plan execution.
## Root Cause
On thread switch, the TUI rebuilds `ChatWidget`, replays buffered thread
events, then drains any queued live events.
In this flow, a `TurnComplete` can be handled twice for the same logical
turn:
1. replayed (`from_replay = true`)
2. then live (`from_replay = false`)
`ChatWidget` used `saw_plan_item_this_turn` to decide whether to show
the plan implementation prompt, but that flag was only reset on
`TurnStarted`.
If duplicate completion events occurred, stale `saw_plan_item_this_turn
= true` could cause the prompt to re-trigger unexpectedly.
## Fix
- Clear `saw_plan_item_this_turn` at the end of `on_task_complete`,
after prompt gating runs.
- This keeps the flag truly turn-scoped and prevents duplicate
`TurnComplete` handling from reopening the prompt.
## 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.

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:`

- shows names of threads in the ResumePicker used by `/resume` and
`codex resume` if set, default to preview (previous behaviour) if none
- adds a `find_thread_names_by_ids` that maps names to IDs in
`codex-rs/core/src/rollout/session_index.rs`. It reads sequentially in
normal (instead of reverse order in `codex resume <name>`) the index
mapping file. This function is called from a list of session (default
page is 25, pages loaded depends of height of terminal), for which most
of them will always have at least one session unnamed and require the
whole file to be read therefore. Could be better and sqlite integration
will make this better
- those reads won't be needed when leveraging sqlite
Opened questions:
- We could rename the TUI "Conversation" column to "Name" or "Thread"
that would feel more accurate. Could be a fast-follow if we implement
auto-naming as it'll always be a name instead?
