We are removing feature-gated shared crates from the `codex-rs`
workspace. `codex-common` grouped several unrelated utilities behind
`[features]`, which made dependency boundaries harder to reason about
and worked against the ongoing effort to eliminate feature flags from
workspace crates.
Splitting these utilities into dedicated crates under `utils/` aligns
this area with existing workspace structure and keeps each dependency
explicit at the crate boundary.
## What changed
- Removed `codex-rs/common` (`codex-common`) from workspace members and
workspace dependencies.
- Added six new utility crates under `codex-rs/utils/`:
- `codex-utils-cli`
- `codex-utils-elapsed`
- `codex-utils-sandbox-summary`
- `codex-utils-approval-presets`
- `codex-utils-oss`
- `codex-utils-fuzzy-match`
- Migrated the corresponding modules out of `codex-common` into these
crates (with tests), and added matching `BUILD.bazel` targets.
- Updated direct consumers to use the new crates instead of
`codex-common`:
- `codex-rs/cli`
- `codex-rs/tui`
- `codex-rs/exec`
- `codex-rs/app-server`
- `codex-rs/mcp-server`
- `codex-rs/chatgpt`
- `codex-rs/cloud-tasks`
- Updated workspace lockfile entries to reflect the new dependency graph
and removal of `codex-common`.
## Why
`codex-core` was being built in multiple feature-resolved permutations
because test-only behavior was modeled as crate features. For a large
crate, those permutations increase compile cost and reduce cache reuse.
## Net Change
- Removed the `test-support` crate feature and related feature wiring so
`codex-core` no longer needs separate feature shapes for test consumers.
- Standardized cross-crate test-only access behind
`codex_core::test_support`.
- External test code now imports helpers from
`codex_core::test_support`.
- Underlying implementation hooks are kept internal (`pub(crate)`)
instead of broadly public.
## Outcome
- Fewer `codex-core` build permutations.
- Better incremental cache reuse across test targets.
- No intended production behavior change.
Added multi-limit support end-to-end by carrying limit_name in
rate-limit snapshots and handling multiple buckets instead of only
codex.
Extended /usage client parsing to consume additional_rate_limits
Updated TUI /status and in-memory state to store/render per-limit
snapshots
Extended app-server rate-limit read response: kept rate_limits and added
rate_limits_by_name.
Adjusted usage-limit error messaging for non-default codex limit buckets
Problem:
1. turn id is constructed in-memory;
2. on resuming threads, turn_id might not be unique;
3. client cannot no the boundary of a turn from rollout files easily.
This PR does three things:
1. persist `task_started` and `task_complete` events;
1. persist `turn_id` in rollout turn events;
5. generate turn_id as unique uuids instead of incrementing it in
memory.
This helps us resolve the issue of clients wanting to have unique turn
ids for resuming a thread, and knowing the boundry of each turn in
rollout files.

```
backward compatibility:
if you try to resume an old session without task_started and
task_complete event populated, the following happens:
- If you resume and do nothing: those reconstructed historical IDs can
differ next time you resume.
- If you resume and send a new turn: the new turn gets a fresh UUID from
live submission flow and is persisted, so that new turn’s ID is stable
on later resumes.
I think this behavior is fine, because we only care about deterministic
turn id once a turn is triggered.
## Summary
This PR fixes TUI transcript-sync behavior for
`EventMsg::ThreadRolledBack` and makes rollback application order
deterministic.
Previously, rollback handling depended on `pending_rollback`:
- if `pending_rollback` was set (local backtrack), TUI trimmed correctly
- otherwise, replayed/external rollbacks were either ignored or could be
applied at the wrong time relative to queued transcript inserts
This change keeps the local backtrack path intact and routes non-pending
rollbacks through the app event queue so rollback trims are applied in
FIFO order with transcript cell inserts.
## What changed
- Added/used `trim_transcript_cells_drop_last_n_user_turns(...)` for
rollback-by-`num_turns` semantics.
- Renamed rollback app event:
- `AppEvent::ApplyReplayedThreadRollback` ->
`AppEvent::ApplyThreadRollback`
- Replay path (`ChatWidget`) now emits `ApplyThreadRollback`.
- Live non-pending rollback path (`App::handle_backtrack_event`) now
emits `ApplyThreadRollback` instead of trimming immediately.
- App-level event handler applies `ApplyThreadRollback` after queued
`InsertHistoryCell` events and schedules redraw only when a trim
occurred.
- When a trim occurs with an overlay open, TUI now syncs transcript
overlay committed cells, clamps backtrack preview selection, and clears
stale `deferred_history_lines` so closed overlays do not re-append
rolled-back lines.
- Clarified inline comments around the `pending_rollback` branch so
future readers can reason about why there are two paths.
## Why queueing matters
During resume/replay, transcript cells are populated via queued
`InsertHistoryCell` app events. If a rollback is applied immediately
outside that queue, it can run against an incomplete transcript and
under-trim. Queueing non-pending rollbacks ensures consistent ordering
and correct final transcript state.
## Behavior by rollback source
- `pending_rollback = Some(...)` (local backtrack requested by this
TUI):
- use `finish_pending_backtrack()` and the stored selection boundary
- `pending_rollback = None` (replay/external/non-local rollback):
- enqueue `AppEvent::ApplyThreadRollback { num_turns }` and trim in
app-event order
## Tests
Added/updated tests covering ordering and semantics:
-
`app_backtrack::tests::trim_drop_last_n_user_turns_applies_rollback_semantics`
- `app_backtrack::tests::trim_drop_last_n_user_turns_allows_overflow`
- `app::tests::replayed_initial_messages_apply_rollback_in_queue_order`
-
`app::tests::live_rollback_during_replay_is_applied_in_app_event_order`
-
`app::tests::queued_rollback_syncs_overlay_and_clears_deferred_history`
- `chatwidget::tests::replayed_thread_rollback_emits_ordered_app_event`
Validation run:
- `just fmt`
- `cargo test -p codex-tui`
As of this PR, `SessionServices` retains a
`Option<StartedNetworkProxy>`, if appropriate.
Now the `network` field on `Config` is `Option<NetworkProxySpec>`
instead of `Option<NetworkProxy>`.
Over in `Session::new()`, we invoke `NetworkProxySpec::start_proxy()` to
create the `StartedNetworkProxy`, which is a new struct that retains the
`NetworkProxy` as well as the `NetworkProxyHandle`. (Note that `Drop` is
implemented for `NetworkProxyHandle` to ensure the proxies are shutdown
when it is dropped.)
The `NetworkProxy` from the `StartedNetworkProxy` is threaded through to
the appropriate places.

Stack created with [Sapling](https://sapling-scm.com). Best reviewed

* #11285
* __->__ #11207
With this PR we do not close the unified exec processes (i.e. background
terminals) at the end of a turn unless:
* The user interrupt the turn
* The user decide to clean the processes through `app-server` or
`/clean`
I made sure that `codex exec` correctly kill all the processes
There are two concepts of apps that we load in the harness:
- Directory apps, which is all the apps that the user can install.
- Accessible apps, which is what the user actually installed and can be
$ inserted and be used by the model. These are extracted from the tools
that are loaded through the gateway MCP.
Previously we wait for both sets of apps before returning the full apps
list. Which causes many issues because accessible apps won't be
available to the UI or the model if directory apps aren't loaded or
failed to load.
In this PR we are separating them so that accessible apps can be loaded
separately and are instantly available to be shown in the UI and to be
provided in model context. We also added an app-server event so that
clients can subscribe to also get accessible apps without being blocked
on the full app list.
- [x] Separate accessible apps and directory apps loading.
- [x] `app/list` request will also emit `app/list/updated` notifications
that app-server clients can subscribe. Which allows clients to get
accessible apps list to render in the $ menu without being blocked by
directory apps.
- [x] Cache both accessible and directory apps with 1 hour TTL to avoid
reloading them when creating new threads.
- [x] TUI improvements to redraw $ menu and /apps menu when app list is
updated.
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.

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.
## 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

## 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:`
custom commands only.

## Summary
- Stream proposed plans in Plan Mode using `<proposed_plan>` tags parsed
in core, emitting plan deltas plus a plan `ThreadItem`, while stripping
tags from normal assistant output.
- Persist plan items and rebuild them on resume so proposed plans show
in thread history.
- Wire plan items/deltas through app-server protocol v2 and render a
dedicated proposed-plan view in the TUI, including the “Implement this
plan?” prompt only when a plan item is present.

- Added a generic, line-based tag parser that buffers each line until it
can disprove a tag prefix; implements auto-close on `finish()` for
unterminated tags. `codex-rs/core/src/tagged_block_parser.rs`
- Refactored proposed plan parsing to wrap the generic parser.
`codex-rs/core/src/proposed_plan_parser.rs`
- In plan mode, stream assistant deltas as:
- **Normal text** → `AgentMessageContentDelta`
- **Plan text** → `PlanDelta` + `TurnItem::Plan` start/completion
(`codex-rs/core/src/codex.rs`)
- Final plan item content is derived from the completed assistant
message (authoritative), not necessarily the concatenated deltas.
- Strips `<proposed_plan>` blocks from assistant text in plan mode so
tags don’t appear in normal messages.
(`codex-rs/core/src/stream_events_utils.rs`)
- Persist `ItemCompleted` events only for plan items for rollout replay.
(`codex-rs/core/src/rollout/policy.rs`)
- Guard `update_plan` tool in Plan Mode with a clear error message.
(`codex-rs/core/src/tools/handlers/plan.rs`)
- Updated Plan Mode prompt to:
- keep `<proposed_plan>` out of non-final reasoning/preambles
- require exact tag formatting
- allow only one `<proposed_plan>` block per turn
(`codex-rs/core/templates/collaboration_mode/plan.md`)
### Protocol / App-server protocol
- Added `TurnItem::Plan` and `PlanDeltaEvent` to core protocol items.
(`codex-rs/protocol/src/items.rs`, `codex-rs/protocol/src/protocol.rs`)
- Added v2 `ThreadItem::Plan` and `PlanDeltaNotification` with
EXPERIMENTAL markers and note that deltas may not match the final plan
item. (`codex-rs/app-server-protocol/src/protocol/v2.rs`)
- Added plan delta route in app-server protocol common mapping.
(`codex-rs/app-server-protocol/src/protocol/common.rs`)
- Rebuild plan items from persisted `ItemCompleted` events on resume.
(`codex-rs/app-server-protocol/src/protocol/thread_history.rs`)
### App-server
- Forward plan deltas to v2 clients and map core plan items to v2 plan
items. (`codex-rs/app-server/src/bespoke_event_handling.rs`,
`codex-rs/app-server/src/codex_message_processor.rs`)
- Added v2 plan item tests.
(`codex-rs/app-server/tests/suite/v2/plan_item.rs`)
### TUI
- Added a dedicated proposed plan history cell with special background
and padding, and moved “• Proposed Plan” outside the highlighted block.
(`codex-rs/tui/src/history_cell.rs`, `codex-rs/tui/src/style.rs`)
- Only show “Implement this plan?” when a plan item exists.
(`codex-rs/tui/src/chatwidget.rs`,
`codex-rs/tui/src/chatwidget/tests.rs`)

/>
### Docs / Misc
- Updated protocol docs to mention plan deltas.
(`codex-rs/docs/protocol_v1.md`)
- Minor plumbing updates in exec/debug clients to tolerate plan deltas.
(`codex-rs/debug-client/src/reader.rs`, `codex-rs/exec/...`)
## Tests
- Added core integration tests:
- Plan mode strips plan from agent messages.
- Missing `</proposed_plan>` closes at end-of-message.
(`codex-rs/core/tests/suite/items.rs`)
- Added unit tests for generic tag parser (prefix buffering, non-tag
lines, auto-close). (`codex-rs/core/src/tagged_block_parser.rs`)
- Existing app-server plan item tests in v2.
(`codex-rs/app-server/tests/suite/v2/plan_item.rs`)
## Notes / Behavior
- Plan output no longer appears in standard assistant text in Plan Mode;
it streams via `PlanDelta` and completes as a `TurnItem::Plan`.
- The final plan item content is authoritative and may diverge from
streamed deltas (documented as experimental).
- Reasoning summaries are not filtered; prompt instructs the model not
to include `<proposed_plan>` outside the final plan message.

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

## Problem
OpenAI employees were sent to the public GitHub issue flow after
`/feedback`, which is the wrong follow-up path internally.
## Mental model
After feedback upload completes, we render a follow-up link/message.
That link should be audience-aware but must not change the upload
pipeline itself.
## Non-goals
- Changing how feedback is captured or uploaded
- Changing external user behavior
## Tradeoffs
We detect employees via the authenticated account email suffix
(`@openai.com`). If the email is unavailable (e.g., API key auth), we
default to the external behavior.
## Architecture
- Introduce `FeedbackAudience` and thread it from `App` -> `ChatWidget`
-> `FeedbackNoteView`
- Gate internal messaging/links on `FeedbackAudience::OpenAiEmployee`
- Internal follow-up link is now `http://go/codex-feedback-internal`
- External GitHub URL remains byte-for-byte identical
## Observability
No new telemetry; this only changes rendered follow-up instructions.
## Tests
- `just fmt`
- `cargo test -p codex-tui --lib`
## 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.

###### Problem
Users get generic 429s with no guidance when a model is at capacity.
###### Solution
Detect model-cap headers, surface a clear “try a different model”
message, and keep behavior non‑intrusive (no auto‑switch).
###### Scope
CLI/TUI only; protocol + error mapping updated to carry model‑cap info.
###### Tests
- just fmt
- cargo test -p codex-tui
- cargo test -p codex-core --lib
shell_snapshot::tests::try_new_creates_and_deletes_snapshot_file --
--nocapture (ran in isolated env)
- validate local build with backend

- [x] Support `/apps` slash command to browse the apps in tui.
- [x] Support inserting apps to prompt using `$`.
- [x] Lots of simplification/renaming from connectors to apps.
## Summary
Sets up an explicit Feature flag for `/personality`, so users can now
opt in to it via `/experimental`. #10114 also updates the config
## Testing
- [x] Tested locally
**Summary**
- Up/Down input history now restores image attachments and text elements
for local entries.
- Composer history stores rich local entries (text + text elements +
local image paths) while persistent history remains text-only.
- Added tests to verify history recall rehydrates image placeholders and
attachments in both `tui` and `tui2`.
**Changes**
- `tui/src/bottom_pane/chat_composer_history.rs`: store `HistoryEntry`
(text + elements + image paths) for local history; adapt navigation +
tests.
- `tui2/src/bottom_pane/chat_composer_history.rs`: same as above.
- `tui/src/bottom_pane/chat_composer.rs`: record rich history entries
and restore them on Up/Down; update Ctrl+C history and tests.
- `tui2/src/bottom_pane/chat_composer.rs`: same as above.
We've recently standardized a [feature maturity
model](https://developers.openai.com/codex/feature-maturity) that we're
using in our docs and support forums to communicate expectations to
users. This PR updates the internal stage names and descriptions to
match.
This change involves a simple internal rename and updates to a few
user-visible strings. No functional change.
## Summary
Adds /personality selector in the TUI, which leverages the new core
interface in #9644
Notes:
- We are doing some of our own state management for model_info loading
here, but not sure if that's ideal. open to opinions on simpler
approach, but would like to avoid blocking on a larger refactor
- Right now, the `/personality` selector just hides when the model
doesn't support it. we can update this behavior down the line
## Testing
- [x] Tested locally
- [x] Added snapshot tests
Keep an unmasked base collaboration mode and apply the active mask on
demand. Simplify the TUI mask helpers and update tests/docs to match the
mask contract.
## Summary
- Replace the plan‑implementation prompt with a standard selection
popup.
- “Yes” submits a user turn in Execute via a dedicated app event to
preserve normal transcript behavior.
- “No” simply dismisses the popup.

/>
## Changes
- Add a plan‑implementation popup using `SelectionViewParams`.
- Add `SubmitUserMessageWithMode` so “Yes” routes through
`submit_user_message` (ensures user history + separator state).
- Track `saw_plan_update_this_turn` so the prompt appears even when only
`update_plan` is emitted.
- Suppress the plan popup on replayed turns, when messages are queued,
or when a rate‑limit prompt is pending.
- Add `execute_mode` helper for collaboration modes.
- Add tests for replay/queued/rate‑limit guards and plan update without
final message.
- Add snapshots for both the default and “No”‑selected popup states.
## Summary
Support updating Personality mid-Thread via UserTurn/OverwriteTurn. This
is explicitly unused by the clients so far, to simplify PRs - app-server
and tui implementations will be follow-ups.
## Testing
- [x] added integration tests
