## Summary
- remove the redundant `needsAuth` field from `AppSummary` and generated
app-server schemas
- stop `plugin/read` from querying Apps MCP solely to hydrate unused
connector auth state
- preserve `plugin/install.appsNeedingAuth` membership and
`app/list.isAccessible` as the authentication signals
## Why
Codex App and TUI do not consume `plugin/read.plugin.apps[].needsAuth`.
Hydrating it could establish an Apps MCP connection and discover tools
on a cold `plugin/read` request, adding avoidable latency. The plugin
APIs are still marked under development, so removing this wire field is
preferable to retaining a misleading default.
## Verification
- `just write-app-server-schema`
- `just fmt`
- `just test -p codex-app-server-protocol`
- `just test -p codex-app-server
plugin_install_uses_remote_apps_needing_auth_response`
- `just test -p codex-app-server

- `just test -p codex-tui
plugin_detail_popup_snapshot_shows_install_actions_and_capability_summaries`
- `$xin-build` simplify and debug reviews
## Why
External-agent import should be discoverable and deliberate without
blocking startup or claiming the public `codex [PROMPT]` CLI namespace.
The slash command keeps the flow local to the interactive TUI and reuses
the existing app-server import API.
## What changed
- add the user-facing `/import` slash command
- detect external-agent importable items only when the command is
invoked
- run imports through the embedded local app-server
- show start and completion messages, refresh configuration, and block
duplicate imports while one is pending
- reject the flow for unsupported remote and local-daemon sessions
## Validation
- `just test -p codex-tui external_agent_config_migration` (10 passed)
- manually exercised an isolated TUI fixture with existing
external-agent setup and session data using a fresh `CODEX_HOME`
- verified picker customization, plugin and session detection, import
completion, repeated invocation, and imported-session resume context
- the broader `just test -p codex-tui` run passed 2,805 tests, with 2
unrelated guardian feature-flag failures and 4 skipped tests
## Draft follow-ups
- review whether completion messaging should remain attached to the
initiating chat if the user switches chats during an import
- review shutdown semantics for an in-progress background import

## Why
MCP startup status notifications are thread-owned, but `ChatWidget`
trusted upstream routing. If routing state delivered a tagged child
notification to the active parent widget, the child MCP failure could
still mutate the parent's startup state and transcript. Rejecting it
only inside the MCP handler was also too late because shared
notification handling could already restore and consume the parent's
retry status.
## What changed
- Validate a tagged MCP status notification against the visible
`ChatWidget` thread before shared notification handling mutates any
parent state.
- Cover child `Starting` and `Failed` notifications delivered to a
retrying parent widget, asserting that they preserve its visible retry
error and saved status header while producing no history or MCP status
mutation.
## User impact
Subagent MCP startup failures remain scoped to the child transcript
instead of appearing as duplicate warnings in the parent transcript.
## Testing
- `just test -p codex-tui mcp_startup_ignores_status_for_other_thread`
- `just test -p codex-tui
primary_thread_ignores_child_mcp_startup_notifications`
- `just fmt`
## Why
The TUI still reached through `app-server-client::legacy_core` for
thread-name normalization and project-instruction filename details. In
particular, checking the TUI's local filesystem for `/init` is incorrect
for remote app-server sessions, where the server owns the working
directory and instruction discovery.
## What changed
- use the instruction source paths supplied by the app server to decide
whether `/init` should avoid overwriting project instructions
- keep the small thread-name normalization helper local to the TUI
- remove the now-unused instruction filename constants, utility module,
and other unused `legacy_core` re-exports
- make status helper tests independent of concrete instruction filenames
## Verification
- `just test -p codex-app-server-client`
- `just test -p codex-tui
slash_init_skips_when_project_instructions_are_loaded`
- `just test -p codex-tui` ran 2,799 tests; 2,797 passed and two
unrelated guardian feature-flag tests failed reproducibly in untouched
code
### Manual test
Started an app server over WebSocket with a remote workspace containing
`AGENTS.md`, then connected the TUI using `--remote`. After confirming
`thread/start` returned the file in `instructionSources`, deleted
`AGENTS.md` and ran `/init` in the existing session.
The TUI still reported that project instructions already existed and
skipped `/init`. The trace contained no `turn/start` request, confirming
the decision came from app-server session state rather than a new
client-local filesystem check.
This changes the `/review` escape path so `Esc` no longer behaves like
the normal queued-follow-up interrupt flow while a review is running.
Steering is not currently supported in `/review` mode, without this
change users are able to attempt a steer but it leads to a crash (see
#22815). If the user has already tried to send additional guidance
during `/review`, the TUI now keeps the review running and shows a
warning that steer messages are not supported in that mode, while still
pointing users to `Ctrl+C` if they actually want to cancel. It also adds
regression coverage for the review-specific warning behavior. When users
do cancel with Ctrl+C during /review, the TUI now tolerates the
active-turn race that can happen during review handoff, and any queued
steer messages are restored to the composer instead of being discarded.
- Special-case `Esc` during an active `/review` when follow-up steer
input is pending or has already been deferred.
- Show a clear warning instead of interrupting the running review.
- Make the Ctrl+C cancel path during /review resilient to active-turn
races, while preserving any queued steer text by restoring it to the
composer.
- Add review-mode test coverage for the warning path.
## Testing
1. Start a `/review` with a diff large enough that the review stays
active for more than a few seconds.
2. While the review is still running, type a follow-up / steer message,
submit it, and then press `Esc`.
Before: `Esc` causes the TUI to close abruptly.
After: the review keeps running and the transcript shows a warning that
steer messages are not supported during `/review`, with guidance to use
`Ctrl+C` if you want to cancel.
3. Press `Ctrl+C` if you actually want to stop the review.
Before: (after restarting the test since Pt. 2 crashed) this is the
intentional cancellation path.
After: this remains the intentional cancellation path, and any queued
follow-up steer text is restored to the composer instead of being lost.
## Note:
`/review` mode explicitly does not support steering at this time (as
noted in `turn_processer.rs`, if we want to explore that in the future
this code will need to be modified). This change keeps unsupported steer
attempts from crashing the TUI and preserves queued follow-up text if
the user cancels with Ctrl+C.
## Why
MCP startup failures from spawned subagents were rendered as global
notifications, so a child thread's failure could pollute the visible
parent transcript. Routing the notification to the child exposed two
related replay problems: session refresh could discard the buffered
event, and a newly created child `ChatWidget` did not know the expected
MCP server set, which could leave its startup spinner running after
every server had settled.
MCP startup diagnostics should remain visible in the thread that owns
the startup without affecting other transcripts. The protocol also needs
to support a future app-scoped MCP lifecycle where startup is not owned
by any thread.
## Reported Behavior
The [originating Slack
report](https://openai.slack.com/archives/C08JZTV654K/p1780604538859939)
called out that using subagents could turn MCP startup failures into a
wall of yellow CLI warnings because repeated failures were not
deduplicated. The intended behavior is for those diagnostics to remain
visible once in the thread that owns the startup, without polluting the
parent transcript.
## What Changed
- add nullable `threadId` ownership to `mcpServer/startupStatus/updated`
- populate it from the app-server conversation ID for the current
thread-scoped lifecycle and regenerate the protocol schema and
TypeScript artifacts
- treat a missing or null `threadId` as app-scoped without injecting it
into the active chat transcript
- route and buffer thread-owned MCP startup notifications by thread in
the TUI
- preserve buffered MCP startup events across child session refresh
- seed expected MCP servers before replaying a thread snapshot so
startup reaches its terminal state
- suppress an identical repeated failure warning for the same server
within one startup round
The owning thread still renders the detailed failure and final `MCP
startup incomplete (...)` summary.
## How to Test
1. Configure an optional MCP server named `smoke` that exits during
initialization.
2. Launch the TUI with multi-agent support enabled.
3. Confirm the main thread's own startup failure renders one detailed
`smoke` warning and one incomplete-startup summary.
4. Spawn exactly one subagent.
5. Confirm the parent transcript does not receive the subagent's MCP
startup failure.
6. Switch to the subagent thread and confirm it contains exactly one
detailed `smoke` failure and one incomplete-startup summary.
7. Confirm the subagent's MCP startup spinner disappears and the thread
remains usable.
8. Switch between the parent and subagent and confirm the warnings
neither move nor duplicate.
Targeted tests:
- `just test -p codex-app-server-protocol`
- `just test -p codex-app-server
thread_start_emits_mcp_server_status_updated_notifications`
- `just test -p codex-tui mcp_startup`
The parent/child behavior and spinner completion were also exercised
manually in tmux. `just argument-comment-lint` was attempted but blocked
by an unrelated local Bazel LLVM empty-glob failure; touched Rust
callsites were inspected manually.
## Why
Pressing `Esc` on a turn that produced no visible output restores the
submitted prompt so the user can keep editing it. That restore path
preserved the prompt content, images, and mention bindings, but left the
composer cursor at the start of the restored text. The next edit
therefore inserted at the beginning instead of continuing from the end
of the prompt.
## What Changed
- Move the cursor to the end after
`BottomPane::set_composer_text_with_mention_bindings` rehydrates a
restored draft.
- Add test-only cursor accessors so restore tests can assert the
composer state directly.
- Extend the queued restore regression to assert the restored composer
cursor is positioned at `text.len()`.
## How to Test
Manual reviewer flow:
1. Start Codex in the TUI.
2. Submit a prompt that will take long enough to interrupt.
3. Press `Esc` before any visible assistant output appears.
4. Confirm the prompt is restored into the composer and the cursor is at
the end, so typing appends to the prompt.
5. Repeat with a prompt that includes an attached image or resolved
mention and confirm the restored content remains intact.
Targeted tests:
- `just test -p codex-tui
chatwidget::tests::composer_submission::queued_restore_with_remote_images_keeps_local_placeholder_mapping`
Lint note:
- `just argument-comment-lint` is blocked locally by the existing Bazel
`compiler-rt` empty glob failure before analyzing touched code. The
touched Rust diff was manually inspected and adds no new opaque
positional literal callsites.
## Why
The TUI's `/goal` usage text only advertised the objective form even
though `/goal clear`, `/goal edit`, `/goal pause`, and `/goal resume`
are implemented. This made the lifecycle controls difficult to discover
and allowed the duplicated help text to drift from actual behavior.
Fixes#25530.
## What changed
- Show the complete `/goal [<objective>|clear|edit|pause|resume]` syntax
in usage messages.
- Share one usage string across slash-command dispatch and goal-related
app messages.
- Add inline snapshot coverage for the control-command usage path.
## Summary
TUI config writes currently wrap app-server failures with local context
like `config/batchWrite failed in TUI`, but several user-visible paths
only render the outer error. That hides the actionable app-server
message, such as validation constraints or read-only `CODEX_HOME`
failures, leaving users with a dead-end diagnostic.
This change adds a small formatter next to the TUI config write helpers
that renders the error source chain, then uses it for model persistence,
feature persistence, project trust, status line writes, hook trust, and
hook enablement.
Fixes#26077
## Summary
- preserve the model catalog order for app-server
`supportedReasoningEfforts` and document that client contract
- render TUI reasoning choices in the advertised order
- step reasoning shortcuts by adjacent list position instead of deriving
order from known effort names
- anchor unsupported configured values to the advertised default, or the
first option when needed
- remove canonical effort ordering helpers and the unused upgrade effort
mapping
## Validation
- `just fmt`
- Local tests and compilation were not run per request; relying on CI.
Stacked on #26444.
## Summary
- accept non-empty model-defined reasoning effort values while
preserving built-in effort behavior
- propagate the non-Copy effort type through core, app-server, TUI,
telemetry, and persistence call sites
- preserve string wire encoding and expose an open-string schema for
clients
- update model selection and shortcut behavior for model-advertised
effort values
## Root cause
`ReasoningEffort` gained a string-backed custom variant, so it could no
longer implement `Copy` or rely on derived closed-enum serialization.
Existing consumers still moved effort values from shared references and
assumed a fixed built-in value set.
## Validation
- `just fmt`
- Local tests and compilation were not run per request; relying on CI.
Fixes#26025.
## Why
`/goal edit` opens `CustomPromptView`, which did not use the paste-burst
handling that protects the main composer when terminals deliver paste as
rapid key events. On Windows terminals, the first pasted newline could
be treated as Enter-to-submit, truncating the goal edit and leaving the
rest of the paste behind.
## What
This reuses `PasteBurst` in `CustomPromptView` as a lightweight
Enter-suppression detector for paste-like key streams. Characters still
insert directly, explicit paste still goes through the view paste path,
and ordinary text entry still submits on Enter.
## Stack
1. #25850 - Key request-permission grants by environment: stores and
applies sticky permission grants per environment id.
2. #25858 - Add `environmentId` to `request_permissions`: lets the model
target a selected environment and resolves relative permission paths
against it.
3. This PR (#25862) - Propagate permission approval environment id:
carries the selected environment id through approval events, app-server
requests, TUI prompts, and delegate forwarding.
4. #25867 - Add remote request permissions integration coverage:
verifies the selected remote environment across request, approval, grant
reuse, and exec.
This PR is stacked on #25858, and #25867 is stacked on this PR.
## Why
PR2 lets the model bind a `request_permissions` call to a selected
environment, but the approval event and client-facing request still
needed to carry that binding. For CCA, the user-facing prompt and
delegated approval path should know which environment the grant applies
to instead of relying on cwd alone.
## What Changed
- Added optional `environmentId` to `RequestPermissionsEvent`.
- Emit the selected environment id from core permission approval events.
- Preserve the environment id through delegate forwarding, including
cwd-based delegated requests.
- Added `environmentId` to app-server permission approval params,
generated schema/TypeScript artifacts, and README examples.
- Preserve and display the environment id in TUI permission approval
prompts.
- Updated focused core, app-server protocol, and TUI conversion
coverage.
## Testing
Not run locally per instruction. Performed read-only `git diff --check`.
## Summary
Enterprise users can have an effective monthly credit limit, but Codex
`/status` currently drops that metadata from the account-usage response.
This change adds the optional `spend_control.individual_limit`
projection to the existing rate-limit snapshot flow. The backend client
reads the monthly limit, app-server exposes it as `individualLimit`, and
the TUI renders a `Monthly credit limit` row through the existing
progress-bar renderer.
When the backend does not return an effective monthly limit, existing
rate-limit behavior is unchanged.
## Existing backend state
The account-usage backend already returns the effective monthly limit
and current usage together:
```json
{
"spend_control": {
"reached": false,
"individual_limit": {
"limit": "25000",
"used": "8000",
"remaining": "17000",
"used_percent": 32,
"remaining_percent": 68,
"reset_after_seconds": 86400,
"reset_at": 1778137680
}
}
}
```
Before this change, Codex projected rolling `primary` and `secondary`
windows plus `credits`. It ignored `spend_control.individual_limit`, so
app-server clients and `/status` could not render the monthly cap.
The updated flow is:
```text
account usage backend
-> backend-client reads spend_control.individual_limit
-> existing rate-limit snapshot carries optional individual_limit
-> app-server exposes optional individualLimit
-> TUI renders Monthly credit limit
```
## App-server contract
`account/rateLimits/read` and sparse `account/rateLimits/updated`
notifications now include an additive nullable
`rateLimits.individualLimit` field:
```json
{
"individualLimit": {
"limit": "25000",
"used": "8000",
"remainingPercent": 68,
"resetsAt": 1778137680
}
}
```
In an `account/rateLimits/read` response, `null` means no monthly limit
is available. `account/rateLimits/updated` remains a sparse rolling
notification: clients merge available values into their most recent
`account/rateLimits/read` snapshot or refetch. Nullable account metadata
in a rolling notification does not clear a previously observed value.
## Design decisions
- Extend the existing rate-limit snapshot instead of introducing a
separate request or wire-level update protocol.
- Keep the Codex projection narrow: `/status` needs the effective limit,
current usage, remaining percentage, and reset timestamp.
- Render the monthly row through the existing progress-bar renderer,
with one optional detail line for `8,000 of 25,000 credits used`.
- Keep the backend response optional so existing accounts and older
usage states preserve their current behavior.
- Preserve cached monthly metadata when sparse rolling notifications
omit it. Live account-usage reads remain authoritative and can clear a
removed limit.
## Visual evidence
```text
Monthly credit limit: [██████████████░░░░░░] 68% left (resets 07:08 on 7 May)
8,000 of 25,000 credits used
```
Snapshot:
`codex-rs/tui/src/status/snapshots/codex_tui__status__tests__status_snapshot_includes_enterprise_monthly_credit_limit.snap`
## Testing
Tests: generated app-server schema verification, protocol tests,
backend-client tests, app-server integration coverage, TUI snapshot
coverage, formatting, and workspace lint cleanup.
Closes#24886.
## Why
Users can configure the TUI status line and terminal title with
`model-with-reasoning`, but issue #24886 asks for a compact
reasoning-only item. That lets a setup show just `default`, `low`,
`medium`, `high`, or `xhigh` without repeating the model name.
## What changed
- Added a `reasoning` item for `/statusline` and `/title` setup flows.
- Rendered the item from the effective reasoning effort, including
collaboration-mode overrides.
- Registered `reasoning` with `codex doctor` so Codex-generated
terminal-title config is not reported as invalid.
- Updated TUI setup snapshots so the picker previews include the new
item.
## TL;DR
When you press Esc or Ctrl+C after sending a prompt but before any
output was rendering, it restores the last composer and the message.
## Summary
Cancelling a prompt immediately after submission should behave like
returning to edit that prompt, not like discarding the user's draft.
Today, pressing `Esc` or `Ctrl+C` before Codex responds leaves the
submitted prompt in the transcript and returns an empty composer,
forcing the user to recall or retype it.
When an interrupted turn has not produced substantive visible output,
restore its submitted prompt directly into the composer and roll back
that latest turn. This also covers the first prompt in a fresh thread,
before the TUI has retained a local user-history cell. The restored
draft keeps its text, image attachments, and active collaboration mode
so it can be edited and resubmitted in place.
Restoration is intentionally suppressed once the turn has produced
user-visible activity such as assistant output, tool work, hooks, or
patches. A transient thinking status does not make the prompt
ineligible. Rollback also rebuilds terminal scrollback from the retained
transcript cells so repeated cancellations and terminal resizes do not
duplicate history.
## How to Test
1. Start the TUI with `cargo run -p codex-cli --bin codex`.
2. In a fresh thread, submit the first prompt and press `Esc` before
Codex emits substantive output. Confirm that the prompt returns to the
composer for editing and its submitted transcript row is removed.
3. Repeat with `Ctrl+C`, then repeat after at least one completed turn.
Confirm the same behavior.
4. Submit a prompt, wait for assistant output or tool activity, then
cancel. Confirm that the transcript remains intact and the prompt is not
restored into the composer.
5. Cancel several output-free prompts and resize the terminal between
attempts. Confirm that the startup banner, tip, and transcript history
do not duplicate in scrollback.
Targeted tests:
- `just test -p codex-tui cancelled_turn_edit_restores_prompt`
- `just test -p codex-tui
output_free_interrupted_turn_requests_prompt_restore`
- `just test -p codex-tui
visible_output_prevents_cancelled_turn_prompt_restore`
- `just test -p codex-tui
thinking_status_keeps_cancelled_turn_prompt_restore_eligible`
- `just test -p codex-tui
patch_activity_prevents_cancelled_turn_prompt_restore`
The full `just test -p codex-tui` run completed with `2746` passing
tests and two unrelated existing guardian feature-flag failures. `just
argument-comment-lint` remains blocked locally by the existing Bazel
LLVM `compiler-rt` sanitizer-header glob failure; the touched Rust diff
was manually audited for positional literal comments.
# Why
Managed requirements can already constrain sandbox policy choices, but
Windows sandbox implementation selection was still resolved
independently from those requirements. That left the TUI able to
continue through the unelevated fallback even when an organization wants
to require the elevated Windows sandbox implementation.
# What
- Add `[windows].allowed_sandbox_implementations` requirements support
for the Windows `elevated` and `unelevated` implementations.
- Apply that allowlist during core config resolution so disallowed
configured or feature-selected Windows sandbox implementations fall back
to an allowed implementation with the existing requirements warning
path.
- Reuse the existing TUI Windows setup prompts to block disallowed
unelevated continuation, keep required elevated setup in front of the
user, and refuse to persist a TUI-selected Windows sandbox mode that
requirements disallow.
# Semantics
| Allowed | Selected | Effective |
| --- | --- | --- |
| `["elevated"]` | `unelevated` / unset | `elevated` |
| `["unelevated"]` | `elevated` / unset | `unelevated` |
| `["elevated", "unelevated"]` | `elevated` | `elevated` |
| `["elevated", "unelevated"]` | `unelevated` | `unelevated` |
| `["elevated", "unelevated"]` | unset | `elevated` |
Availability is handled by interactive setup surfaces after allowlist
resolution. If the effective elevated implementation is not ready,
elevated-only requirements block on setup. When unelevated is also
allowed, the UI may offer the existing unelevated fallback.
## TUI Screens
If elevated setup is not already complete:
```
Your organization requires the default Codex agent sandbox to continue. Set it up to protect your files and control
network access.
Learn more <https://developers.openai.com/codex/windows>
› 1. Set up default sandbox (requires Administrator permissions)
2. Quit
```
If admin setup fails under `["elevated"]`:
```
Couldn't set up your sandbox with Administrator permissions
Your organization requires the default sandbox before Codex can continue.
Learn more <https://developers.openai.com/codex/windows>
› 1. Try setting up admin sandbox again
2. Quit
```
# Next Steps
- extend the requirements/readout surface, such as
`configRequirements/read`, so clients can inspect the loaded
`[windows].allowed_sandbox_implementations` requirement instead of
inferring it from Windows setup state
- consider extending `windowsSandbox/readiness` as well
- update the App startup guide, setup flow, and banner surfaces so an
elevated-only requirement omits any continue-unelevated escape hatch and
blocks startup until a permitted implementation is ready;
- preserve the existing unelevated fallback path when requirements allow
it, including the `["unelevated"]` case where elevated is disallowed
## Why
TUI users can archive saved sessions from other surfaces, but there is
no in-session command for archiving the active session. Since archiving
the active session also exits the TUI, the command should ask for
explicit confirmation instead of firing immediately.
I'm also working on [a companion
PR](https://github.com/openai/codex/pull/25021) that adds `codex
archive` and `codex unarchive` top-level CLI commands.
## What changed
- Adds a new `/archive` slash command described as `archive this session
and exit`.
- Shows a confirmation dialog with `No, don't archive` selected first
and `Yes, archive and exit` as the explicit action.
- On confirmation, calls the existing `thread/archive` app-server RPC
for the active main session and exits after success.
- Keeps `/archive` disabled while a task is running and unavailable in
side conversations.
## Verification
Added focused TUI coverage for the `/archive` confirmation flow,
disabled-while-task-running behavior, and the `/ar` slash-command popup
snapshot.
## Summary
The desktop app now presents the on-request permissions mode as `Ask for
approval` and the manual-review-backed mode as `Approve for me`. The TUI
still exposed older/internal labels like `Default` and `Auto-review`,
which made the same underlying settings look different across clients.
This updates the TUI UX copy to match the app without changing the
underlying default behavior. Fresh threads continue to use the existing
on-request approval mode, now displayed as `Ask for approval`.
The label changes cover `/permissions`, explicit profile permissions
menus, status surfaces, config persistence history/error text, and the
corresponding TUI snapshots.

# Why
Fixes#24529. Completed hook output in the TUI rendered each
`HookOutputEntry` as one ratatui line, so explicit newlines inside hook
output were not shown as separate transcript rows. That made multiline
`SessionStart.additionalContext` hard to inspect even though the
model-facing context path preserved the original text.
# What
- Split completed hook output entries on explicit newlines before
rendering them in `codex-rs/tui/src/history_cell/hook_cell.rs`.
- Keep the hook output prefix, such as `hook context:` or `warning:`, on
the first physical line only.
- Preserve explicit blank lines and render continuation lines with the
hook body indent.
- Add unit coverage for multiline context and warning output, plus a
chatwidget snapshot regression for `SessionStart` history output.
# Testing
- `cargo nextest run -p codex-tui completed_hook_multiline
hook_completed_before_reveal_renders_completed_without_running_flash`
- `just argument-comment-lint -p codex-tui -- --ignore-rust-version
--lib --tests`
## Why
When the TUI resumes a thread, transcript replay renders prior user
messages but did not seed the composer history. That leaves the resumed
session with empty in-memory prompt history, so pressing Up can fall
through to persisted global history and surface a prompt from another
thread.
The expected behavior is that prompts from the resumed thread are
recalled first, with global history only as a fallback.
## What changed
- Record replayed user messages into the composer history during resume
replay.
- Preserve the existing persisted history format and avoid any startup
history scan.
- Add focused TUI coverage showing replayed prompts are recalled before
persisted global history.
## Validation
- Added `replayed_user_messages_seed_composer_history` in
`codex-rs/tui/src/chatwidget/tests/history_replay.rs`.
- `just test -p codex-tui replayed_user_messages_seed_composer_history`
passed.
## Summary
Adds an optional `clientId` field to app-server v2 `UserInput` and
carries it through the core `UserInput` model so clients can correlate
echoed user input items without relying on payload equality.
## Details
- Adds `client_id: Option<String>` to core `UserInput` variants.
- Exposes the v2 app-server field as `clientId` on the wire and in
generated TypeScript.
- Preserves the id when converting between app-server v2 and core
protocol types.
- Regenerates app-server schema fixtures.
## Validation

This change keeps unified @mentions behind the mentions_v2 gate, moves
the flag to under-development, and polishes mention rendering/history
behavior.
It also adds a few small improvements to the mentions feature around
mention rendering and history round-tripping for plugin/tool mentions in
message edit scenarios. Plugin selections now insert `@` mentions with
better casing, and saved history preserves the visible sigil so recalled
messages look the same as what the user typed.
- Preserves `@` sigils when encoding/decoding mention history for
tool/plugin paths.
- Improves plugin mention insertion so display names/casing are
reflected more cleanly in the composer.
- Update composer to render user-entered plugin mentions in the same
color as the mentions menu. ALso applies to recalled/edited messages.
- Left/right arrows no longer switch unified-mention search modes after
an @mention has already been accepted (Ex: arrowing left through a
composed message that contains @mentions).
- Keeps bound mentions stable around punctuation, so accepted `@`
mentions do not reopen the popup and punctuated `$` mentions still
persist to cross-session history.
**Steps to test**
- Ensure mentions_v2 is enabled through configuration or `--enable
mentions_v2`
- Type `@` in the TUI composer and verify filesystem/plugin/skill
results are displayed in the unified mentions menu.
- Select a plugin mention from the `@` popup and confirm the inserted
text is an `@...` mention with casing, then recall/edit the message and
confirm it still renders as `@...`.
- Mention a skill and verify that skills still insert as `$skill`
mentions rather than `@` mentions.
- Verify punctuated mentions such as `@plugin.` and `($skill)` keep
their bound mention behavior across editing and history recall.
## Why
Wrapped URLs in rich TUI output, especially URLs rendered inside
Markdown tables, are split across terminal rows. In terminals that
support OSC 8 hyperlinks, treating each visible fragment as part of the
complete destination enables reliable open-link and copy-link actions
even after table layout wraps the URL.
This addresses the semantic-link portion of #12200 and the behavior
described in
https://github.com/openai/codex/issues/12200#issuecomment-4535452980. It
does not change ordinary drag-selection across bordered table rows.
## What Changed
- Added shared TUI OSC 8 support that validates `http://` and `https://`
destinations, sanitizes terminal payloads, and applies metadata
separately from visible line width/layout.
- Added semantic web-link annotations to assistant and proposed-plan
Markdown, including explicit web links and bare web URLs in prose and
table cells while excluding code and non-web Markdown destinations.
- Preserved complete URL targets through table wrapping, narrow pipe
fallback, streaming, transcript overlay rendering, history insertion,
and resize replay.
- Routed intentional Codex-owned links in notices,
status/setup/app-link, feedback, onboarding, MCP/plugin help, memories,
and update surfaces through the shared hyperlink handling.
## How to Test
1. Run Codex in a terminal with OSC 8 link support, such as Ghostty, and
request an assistant response containing a Markdown table whose last
column contains a long `https://` URL.
2. Make the terminal narrow enough for the URL to wrap across multiple
bordered table rows.
3. Use the terminal's open-link or copy-link action on more than one
wrapped URL fragment and confirm each fragment resolves to the complete
original URL.
4. Resize the terminal after the table is rendered and repeat the link
action to confirm the destination survives scrollback replay.
5. Open the transcript overlay while rich output is present and confirm
web links remain interactive there.
6. As a regression check, render inline/fenced code containing URL text
and a Markdown link such as
`[https://example.com](mailto:support@example.com)`; confirm these do
not acquire a web OSC 8 destination.
Targeted automated coverage exercised Markdown links and exclusions,
wrapped and pipe-fallback tables, streaming/transcript overlay
propagation, status-link truncation, and rendered word-wrapping cell
alignment. `just test -p codex-tui` was also run; it passed the
hyperlink coverage and reproduced two unrelated existing guardian
feature-flag test failures.
## Stack
- **Current: #24489 [1 of 2]** - render markdown tables in app style.
- **Stacked follow-up: #24636 [2 of 2]** - render cramped markdown
tables as key/value records.
## Why
Markdown tables currently render as boxed terminal grids, which gives
ordinary assistant output a heavier visual treatment than surrounding
rich text. This row-separated layout is the best match for how the App
renders tables, while accented headers remain distinguishable even when
a terminal font renders bold subtly.

## What Changed
- Render markdown tables as padded, aligned rows without an enclosing
box.
- Style table headers with the active syntax-theme accent plus bold
text, while keeping separators low contrast and theme-aware.
- Use a segmented heavy header rule and thin body-row rules, preserving
wrapping, narrow-width fallback, streaming parity, and rich-history
rendering.
- Update focused assertions and snapshots for the final table layout.
## How to Test
1. Render a markdown table in the TUI with several rows and columns.
2. Confirm the header uses the active theme accent, rows use
one-character interior padding, and the table has no enclosing box.
3. Confirm the header is followed by segmented `━` rules and multiple
body rows are separated by muted segmented `─` rules.
4. Render the same table while streaming and in history/raw-mode
toggles; the final rich layout should remain stable.
5. Render a narrow table with long content and verify wrapping or pipe
fallback does not overflow.

`update_feature_flags_disabling_guardian_clears_review_policy_and_restores_default`
and
`update_feature_flags_disabling_guardian_clears_manual_review_policy_without_history`.
## Why
Interrupting an active turn is currently fixed to `Esc`, which is easy
to hit accidentally and cannot be customized through `/keymap`. This
gives users a less accidental binding while preserving the existing
default.
## What Changed
- Adds `tui.keymap.chat.interrupt_turn` to `/keymap`, defaulting to
`esc` and supporting remapping or unbinding.
- Uses the configured interrupt binding for running-turn status, queued
steer interruption, and `request_user_input`, including the visible
hints.
- Preserves local `Esc` behavior for popups, Vim insert mode, and
`/agent` editing while validating conflicts with fixed/backtrack and
request-input navigation bindings.
- Adds behavior and snapshot coverage for remapped interruption paths.
## How to Test
1. Run Codex and open `/keymap`, then set **Interrupt Turn** to `f12`.
2. Start a turn and confirm `Esc` no longer interrupts it while `f12`
does; the running hint should display `f12 to interrupt`.
3. Queue a steer while a turn is running and confirm the preview
displays `f12`; pressing it should interrupt and submit the steer
immediately.
4. Trigger a `request_user_input` prompt and confirm its footer uses
`f12`; with notes open, `Esc` should still clear notes while `f12`
interrupts the turn.
5. Clear the Interrupt Turn binding and confirm the key-specific
interrupt hint is removed while `Ctrl+C` remains available.

## Why
Windows sandbox diagnostics are currently hard to recover from
`/feedback` even though they are often the most useful artifact when
debugging sandbox behavior. Now that sandbox logging uses daily rolling
files, feedback can safely include the current day's sandbox log without
uploading the old ever-growing legacy `sandbox.log`.
## What changed
- Add a `codex-windows-sandbox` helper that resolves the current daily
sandbox log from `codex_home`.
- When feedback is submitted with logs enabled on Windows, app-server
attaches today's sandbox log if it exists.
- Upload the attachment under the stable filename `windows-sandbox.log`,
independent of the dated on-disk filename.
- Keep existing raw `extra_log_files` behavior unchanged for rollout and
desktop log attachments.
## Verification

- Manual CLI/TUI `/feedback` test confirmed Sentry received
`windows-sandbox.log`.
## Summary
Fix the TUI `$` app mention paths so App Directory rows that are not
accessible are not treated as usable apps.
This includes the core preservation fix from #24104, but expands it to
the other app mention paths:
- preserve app-server `is_accessible` flags when partial
`app/list/updated` snapshots reach the TUI
- require apps to be both accessible and enabled when resolving exact
`$slug` mentions
- require restored/stale `app://...` bindings to point at accessible,
enabled apps before emitting structured app mentions
- remove the now-unused `codex-chatgpt` dependency from `codex-tui`,
which addresses the `cargo shear` failure seen on #24104
## Root Cause
The app server already sends merged app snapshots with accessibility
computed. The TUI handled app-server app list updates as partial app
loads and re-ran the old accessible-app merge path. That path treated
every notification row as accessible, so App Directory entries with
`isAccessible=false` could appear in `$` suggestions.
Regression source: #22914 routed app-list updates through the app server
while reusing the old TUI partial-load handling. Related precursor:
#14717 introduced the partial-load path, but #22914 made it user-visible
for app-server updates.

## Why
Users who opt into named permission profiles through
`default_permissions` or `[permissions.*]` should stay in named-profile
semantics when they open `/permissions`. The legacy picker rewrites
those users into anonymous preset state, which loses the active profile
identity and hides custom configured profiles.
## What changed
- Switch `/permissions` to a profile-aware picker when profile mode is
active.
- Show friendly built-in labels instead of raw `:` profile syntax.
- Include configured custom profiles and their descriptions in the
picker.
- Route selections through the split TUI profile-selection flow below
this PR.
- Add TUI snapshots and regression coverage for built-ins, custom
profiles, and conflicting legacy runtime overrides.

3. **This PR**: profile-aware `/permissions` menu and custom profile

## UX impact
In profile mode, `/permissions` shows the same human-facing built-ins
users already know:
```text
Default
Auto-review
Full Access
Read Only
locked-down
web-enabled
```
Selecting `locked-down` keeps `active_permission_profile =
Some("locked-down")`; selecting a built-in keeps the friendly label
while switching to its named built-in profile.

## Summary
`/mcp` in the TUI should reflect the current loaded thread, including
project-local MCP servers from that thread config. Before this change,
`mcpServerStatus/list` only read the latest global MCP config, so the
active chat could miss project-local servers.
This adds optional `threadId` to `mcpServerStatus/list`. When present,
app-server resolves the loaded thread and lists MCP status from the
refreshed effective config for that thread; when omitted, existing
global config behavior stays unchanged.
The TUI now sends the active chat thread id for `/mcp` and `/mcp
verbose`, carries that origin through the async inventory result, and
ignores stale completions if the user has switched threads before the
fetch returns. The app-server schemas were regenerated.
## Follow-up
Once this app-server API change lands, the desktop app should make the
same `threadId` plumbing so its MCP inventory also uses the current
thread config.
Fixes#23874
## Summary
The compact TUI status line already renders rate-limit percentages as
remaining capacity, but the text did not say so. That made high-usage
red indicators ambiguous because values like `weekly 6%` could be read
as either used or remaining.
This PR labels the compact rate-limit values explicitly as `left` across
the status line, terminal title, and setup previews.
Addresses #24274
## Why
The named-profile `/permissions` picker needs a small TUI action path
that can select permission profiles without folding the menu UI and
profile metadata into the same review.
## What changed
- Carry permission-profile selections through the TUI app event flow.
- Persist selected profiles while preserving the existing approval
settings and guardrail prompts.
- Keep the legacy `/permissions` picker behavior in this layer; the
profile-mode menu stays in the follow-up PR.

hit shell/sandbox/snapshot failures in the integration target.
- A broader app-server downstream run hit the existing
`in_process::tests::in_process_start_clamps_zero_channel_capacity` stack
overflow; `cargo test -p codex-exec` also hit the existing sandbox
expectation mismatch in
`thread_lifecycle_params_include_legacy_sandbox_when_no_active_profile`.
## Why
Model catalog responses can now advertise a nullable
`default_service_tier` for each model. Codex needs to preserve three
distinct states all the way from config/app-server inputs to inference:
- no explicit service tier, so the client may apply the current model
catalog default when FastMode is enabled
- explicit `default`, meaning the user intentionally wants standard
routing
- explicit catalog tier ids such as `priority`, `flex`, or future tiers
Keeping those states distinct prevents the UI from showing one tier
while core sends another, especially after model switches or app-server
`thread/start` / `turn/start` updates.
## What Changed
- Plumbed `default_service_tier` through model catalog protocol types,
app-server model responses, generated schemas, model cache fixtures, and
provider/model-manager conversions.
- Added the request-only `default` service tier sentinel and normalized
legacy config spelling so `fast` in `config.toml` still materializes as
the runtime/request id `priority`.
- Moved catalog default resolution to the TUI/client side, including
recomputing the effective service tier when model/FastMode-dependent
surfaces change.
- Updated app-server thread lifecycle config construction so
`serviceTier: null` preserves explicit standard-routing intent by
mapping to `default` instead of internal `None`.
- Kept core responsible for validating explicit tiers against the
current model and stripping `default` before `/v1/responses`, without
applying catalog defaults itself.

`SubagentStop` runs when a thread-spawned subagent turn is about to
finish. Thread-spawned subagents use `SubagentStop` instead of the
normal root-agent `Stop` hook.
Configured handlers match on `agent_type`. Hook input includes the
normal stop fields plus:
- `agent_id`: the child thread id.
- `agent_type`: the resolved subagent type.
- `agent_transcript_path`: the child subagent transcript path.
- `transcript_path`: the parent thread transcript path.
- `last_assistant_message`: the final assistant message from the child
turn, when available.
- `stop_hook_active`: `true` when the child is already continuing
because an earlier stop-like hook blocked completion.
`SubagentStop` shares the same completion-control semantics as `Stop`,
scoped to the child turn:
- No decision allows the child turn to finish.
- `decision: "block"` with a non-empty `reason` records that reason as
hook feedback and continues the child with that prompt.
- `continue: false` stops the child turn. If `stopReason` is present,
Codex surfaces it as the stop reason.
# Lifecycle Scope
Only thread-spawned subagents run `SubagentStop`.
Internal/system subagents such as Review, Compact, MemoryConsolidation,
and Other do not run normal `Stop` hooks and do not run `SubagentStop`.
This avoids exposing synthetic matcher labels for internal
implementation paths.
# Stack

2. This PR: add `SubagentStop`.
3. #22882: add subagent identity to normal hook inputs.
## Why
Once a named permission profile is selected, runtime state has to keep
that profile identity intact instead of collapsing back to anonymous
effective permissions. The session refresh path also needs to rebuild
profile-derived network proxy state so active profile switches take
effect consistently.
## What changed
- Preserve the active permission profile through session updates.
- Rebuild profile-derived runtime/network configuration when the active
profile changes.
- Keep the runtime path aligned with the current session configuration
APIs.
- Tighten the affected tests, including the Windows delete-pending
memory-file case that was intermittently tripping CI.

Builds on #23502.
## Why
#23502 adds the app-server `thread/settings/update` API and matching
`thread/settings/updated` notification. The TUI already lets users
change thread-scoped settings such as model, reasoning effort, service
tier, approvals, permissions, personality, and collaboration mode, but
those updates need to flow through the app server so embedded and
connected clients observe the same thread state.
This is a rework (simplification) of PR
https://github.com/openai/codex/pull/22510. It has the same
functionality, but the underlying `thread/settings/update` api is now
simpler in that it no longer returns the effective settings as a
response. Now, clients receive the effective settings only through the
`thread/settings/updated` notification.
## What Changed
This updates the TUI to send `thread/settings/update` whenever those
thread-scoped settings change and to treat the RPC response as the
authoritative acknowledgement. It also routes `thread/settings/updated`
notifications back into cached session state and the visible chat widget
so active and inactive threads stay in sync after app-server-originated
changes.
The implementation is kept to the TUI layer: settings conversion and
merge logic live under `codex-rs/tui/src/app/thread_settings.rs`, with
dispatch/routing hooks in the existing app and chat widget paths.
## Verification
I manually tested using `codex app-server --listen unix://` and then
launching two copies of the TUI that use the same local app server. I
then resumed the same thread on both and verified that changes like plan
mode, fast mode, model, reasoning effort, etc. are reflected "live" in
the second client when modified in the first and vice versa.
## Why
Issue #23214 reports `/ps` showing no background terminals while the
status line still says it is waiting for a background terminal. The race
is in core: `write_stdin` can poll a process that exits before the
response returns. The process manager correctly returns `process_id:
None`, but the handler still emitted a `TerminalInteraction` event using
the requested session id, causing clients to believe a dead process was
still being polled.
Fixes#23214.
## What changed
- Suppress `TerminalInteraction` events for empty `write_stdin` polls
once `response.process_id` is `None`.
- Continue emitting interactions for non-empty stdin, even if that input
causes the process to exit before the response returns.
- Extend the unified exec integration test to assert completed empty
polls do not emit terminal interactions.
## Verification
- `cargo test -p codex-core --test all
unified_exec_emits_one_begin_and_one_end_event`
- `cargo test -p codex-core --test all
unified_exec_emits_terminal_interaction_for_write_stdin`
`cargo test -p codex-core` currently aborts in unrelated

with a reproducible stack overflow.
# What
`SubagentStart` runs once when Codex creates a thread-spawned subagent,
before that child sends its first model request. Thread-spawned
subagents use `SubagentStart` instead of the normal root-agent
`SessionStart` hook.
Configured handlers match on the subagent `agent_type`, using the same
value passed to `spawn_agent`. When no agent type is specified, Codex
uses the default agent type.
Hook input includes the normal session-start fields plus:
- `agent_id`: the child thread id.
- `agent_type`: the resolved subagent type.
`SubagentStart` may return `hookSpecificOutput.additionalContext`. That
context is added to the child conversation before the first model
request.
# Lifecycle Scope
Only thread-spawned subagents run `SubagentStart`.
Internal/system subagents such as Review, Compact, MemoryConsolidation,
and Other do not run normal `SessionStart` hooks and do not run
`SubagentStart`. This avoids exposing synthetic matcher labels for
internal implementation paths.
Also the `SessionStart` hook no longer fires for subagents, this matches
behavior with other coding agents' implementation
# Stack

2. #22873: add `SubagentStop`.

## Context
The CLI rate-limit surfaces previously described usage windows as fixed
5-hour and weekly limits. We want the CLI to display whatever supported
rate-limit period the server returns instead of assuming a 5-hour/1-week
pair. This supports generalized Codex rate-limit periods.
## Summary
- Formats CLI rate-limit warning/status labels only for the supported
returned window durations: approximate 5h, daily, weekly, monthly, and
annual.
- Uses generic fallback copy when a primary or secondary window has no
duration, so missing secondary protection data does not produce stale
weekly copy.
- Uses generic fallback copy for unsupported window durations instead of
adding arbitrary hourly, multi-day, multi-week, or multi-year labels.
- Updates status line and terminal title setup descriptions/previews to
talk about primary/secondary usage limits rather than fixed 5h/weekly
limits.
- Adds rendered insta snapshot coverage for the updated rate-limit
status surfaces and `/status` fallback labels.
## Tests
Tested locally:
- one primary window
- one secondary window
- primary and secondary window
## Why
Filesystem permission profiles used `none` for deny-read entries, which
is less direct than the action the entry actually represents. This
change makes `deny` the canonical filesystem permission spelling while
preserving compatibility for older configs that still send `none`.
## What changed
- rename `FileSystemAccessMode::None` to `Deny`
- serialize and generate schemas with `deny` as the canonical value
- retain `none` only as a legacy input alias for temporary config
compatibility
- update filesystem glob diagnostics and regression coverage to use the
canonical spelling
- refresh config and app-server schema fixtures to match the new wire
shape
## Validation
- `cargo test -p codex-protocol`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-core config_toml_deserializes_permission_profiles
--lib`
- `cargo test -p codex-core
read_write_glob_patterns_still_reject_non_subpath_globs --lib`
Earlier in the session, a broad `cargo test -p codex-core` run reached
unrelated pre-existing failures in timing/snapshot/git-info tests under
this environment; the targeted surfaces touched by this PR passed
cleanly.
## Why
App and skill toggles are user config mutations too. When the TUI is
attached to a remote app server, writing those toggles into the local
`config.toml` makes the UI report success without updating the server
that actually owns the session.
This is **[2 of 4]** in a stacked series that moves TUI-owned config
mutations onto app-server APIs.
## What changed
- Routed app enable/disable persistence through app-server config batch
writes.
- Routed skill enable/disable persistence through `skills/config/write`.
- Avoided refreshing local config from disk after these writes when the
TUI is connected to a remote app server.
## Config keys affected
- `apps.<app_id>.enabled`
- `apps.<app_id>.disabled_reason`
- `[[skills.config]]` entries keyed by `path`, with `enabled = false`
used for persisted disables
## Suggested manual validation
- Connect the TUI to a remote app server, disable an app, reconnect, and
confirm the app remains disabled from remote config rather than local
disk state.
- Re-enable the same app and confirm both `apps.<app_id>.enabled` and
`apps.<app_id>.disabled_reason` are cleared remotely.
- Disable a skill in the manage-skills UI and confirm a remote
`[[skills.config]]` disable entry appears.
- Re-enable that skill and confirm the disable entry is removed and the
effective enabled state updates without relying on local config reloads.

## Why
Older iTerm2 builds can be detected as supporting the image transport
that terminal pets use, but in practice they fail to render the pet flow
correctly. Instead of silently attempting image rendering, Codex should
tell the user that their iTerm2 version is too old and that upgrading is
the fix.
## What Changed
- gate iTerm2 pet auto-detection on version `3.6.0` or newer
- show a dedicated upgrade message for older or unknown iTerm2 versions
instead of the generic unsupported-terminal warning
- keep the existing generic unsupported-terminal path for non-iTerm
terminals
- add regression coverage for iTerm2 version parsing and the old-iTerm
warning path
## How to Test
1. Start Codex in iTerm2 3.6 or newer.
2. Run `/pets`.
3. Confirm the pets picker opens instead of showing a warning.
4. Start Codex in an older iTerm2 build, or exercise the equivalent test
path.
5. Run `/pets`.
6. Confirm Codex warns that pets require iTerm2 3.6 or newer and tells
the user to upgrade.
7. Also verify that a non-iTerm unsupported terminal still shows the
generic unsupported-terminal message.
Targeted tests:
- `cargo test -p codex-terminal-detection`
- `cargo test -p codex-tui pets::`
- `cargo test -p codex-tui slash_pets_on_unsupported_terminal`
- `cargo test -p codex-tui slash_pets_on_old_iterm2`
Fixes#22300.
## Summary
MCP tool calls can appear in thread history while still in progress.
During replay, `handle_thread_item` routed every
`ThreadItem::McpToolCall` to the completion handler, so an in-progress
item with no result or error was rendered as `MCP tool call completed
without a result`.
This updates replay handling to mirror command executions: `InProgress`
MCP calls go through `on_mcp_tool_call_started`, while completed and
failed calls continue through the completion path.
## Validation
- `cargo test -p codex-tui
replayed_in_progress_mcp_tool_call_stays_active`
## Why
Fixes#21894.
When the TUI handles an MCP elicitation, the request payload already
includes the thread that generated the elicitation.
`ChatWidget::handle_elicitation_request_now` was ignoring that value and
using the currently visible chat thread instead. In a multi-session TUI,
that can send `resolve_elicitation` to an older visible thread rather
than the session that owns the pending elicitation, producing
`elicitation request not found` and leaving the prompt unresolved.
## What changed
- Parse `McpServerElicitationRequestParams.thread_id` in the ChatWidget
elicitation handler and use it for app-link, form, fallback approval,
and auto-decline resolution paths.
- Keep the existing visible-thread fallback only for malformed request
payloads with an invalid thread id.
- Update the invalid URL elicitation regression test so the visible
thread and request thread intentionally differ.
