Problem: TUI desktop notifications are hard-gated on terminal focus, so
terminal/IDE hosts that want in-focus notifications cannot opt in.
Solution: Add a flat `[tui] notification_condition` setting (`unfocused`
by default, `always` opt-in), carry grouped TUI notification settings
through runtime config, apply method + condition together in the TUI,
and regenerate the config schema.
When running with remote executor the cwd is the remote path. Today we
check for existence of a local directory on startup and attempt to load
config from it.
For remote executors don't do that.
Adds the `[realtime].transport = "webrtc"` TUI media path using a new
`codex-realtime-webrtc` crate, while leaving app-server as the
signaling/event source.\n\nLocal checks: fmt, diff-check, dependency

Problem: Resuming the live TUI thread through `/resume` could
unsubscribe and reconnect the same app-server thread, leaving the UI
crashed or disconnected.
Solution: No-op `/resume` only when the selected thread is the currently
attached active thread; keep the normal resume path for
stale/displayed-only threads so recovery and reattach still work.
## TL;DR
- Fetches account/rateLimits/read asynchronously so the TUI can continue
starting without waiting for the rate-limit response.
- Fixes the /status card so it no longer leaves a stale “refreshing
cached limits...” notice in terminal history.
## Problem
The TUI bootstrap path fetched account rate limits synchronously
(`account/rateLimits/read`) before the event loop started for
ChatGPT/OpenAI-authenticated startups. This added ~670 ms of blocking
latency in the measured hot-start case, even though rate-limit data is
not needed to render the initial UI or accept user input. The delay was
especially noticeable on hot starts where every other RPC
(`account/read`, `model/list`, `thread/start`) completed in under 70 ms
total.
Moving that fetch to the background also exposed a `/status` UI bug: the
status card is flattened into terminal scrollback when it is inserted. A
transient "refreshing limits in background..." line could not be cleared
later, because the async completion updated the retained `HistoryCell`,
not the already-written terminal history.
## Mental model
Before this change, `AppServerSession::bootstrap()` performed three
sequential RPCs: `account/read` → `model/list` →
`account/rateLimits/read`. The result of the third call was baked into
`AppServerBootstrap` and applied to the chat widget before the event
loop began.
After this change, `bootstrap()` only performs two RPCs (`account/read`
+ `model/list`), and rate-limit fetching is kicked off as an async
background task immediately after the first frame is scheduled. A new
enum, `RateLimitRefreshOrigin`, tags each fetch so the event handler
knows whether the result came from the startup prefetch or from a
user-initiated `/status` command; they have different completion
side-effects.
The `get_login_status()` helper (used outside the main app flow) was
also decoupled: it previously called the full `bootstrap()` just to
check auth mode, wasting model-list and rate-limit work. It now calls
the narrower `read_account()` directly.
For `/status`, this PR keeps the background refresh request but stops
printing transient refresh notices into status history when cached
limits are already available. If a refresh updates the cache, the next
`/status` command will render the new values.
## Non-goals
- This change does not alter the rate-limit data itself.
- This change does not introduce caching, retries, or staleness
management for rate limits.
- This change does not affect the `model/list` or `thread/start` RPCs;
they remain on the critical startup path.
## Tradeoffs
- **Stale-on-first-render**: The status bar will briefly show no
rate-limit info until the background fetch completes; observed
background fetches landed roughly in the 400-900 ms range after the UI
appeared. This is acceptable because the user cannot meaningfully act on
rate-limit data in the first fraction of a second.
- **Error silence on startup prefetch**: If the startup prefetch fails,
the error is logged but the UI is not notified (unlike `/status` refresh
failures, which go through the status-command completion path). This
avoids surfacing transient network errors as a startup blocker.
- **Static `/status` history**: `/status` output is terminal history,
not a live widget. The card now avoids progress-style language that
would appear stuck in scrollback; users can run `/status` again to see
newly cached values.
- **`account_auth_mode` field removed from `AppServerBootstrap`**: The
only consumer was `get_login_status()`, which no longer goes through
`bootstrap()`. The field was dead weight.
## Architecture
### New types
- `RateLimitRefreshOrigin` (in `app_event.rs`): A `Copy` enum
distinguishing `StartupPrefetch` from `StatusCommand { request_id }`.
Carried through `RefreshRateLimits` and `RateLimitsLoaded` events so the
handler applies the right completion behavior.
### Modified types
- `AppServerBootstrap`: Lost `account_auth_mode` and
`rate_limit_snapshots`; gained `requires_openai_auth: bool` (passed
through from the account response so the caller can decide whether to
fire the prefetch).
### Control flow
1. `bootstrap()` returns with `requires_openai_auth` and
`has_chatgpt_account`.
2. After scheduling the first frame, `App::run_inner` fires
`refresh_rate_limits(StartupPrefetch)` if both flags are true.
3. When `RateLimitsLoaded { StartupPrefetch, Ok(..) }` arrives,
snapshots are applied and a frame is scheduled to repaint the status
bar.
4. When `RateLimitsLoaded { StartupPrefetch, Err(..) }` arrives, the
error is logged and no UI update occurs.
5. `/status`-initiated refreshes continue to use `StatusCommand {
request_id }` and call `finish_status_rate_limit_refresh` on completion
(success or failure).
6. `/status` history cells with cached rate-limit rows no longer render
an additional "refreshing limits" notice; the async refresh updates the
cache for future status output.
### Extracted method
- `AppServerSession::read_account()`: Factored out of `bootstrap()` so
that `get_login_status()` can call it independently without triggering
model-list or rate-limit work.
## Observability
- The existing `tracing::warn!` for rate-limit fetch failures is
preserved for the startup path.
- No new metrics or spans are introduced. The startup-time improvement
is observable via the existing `ready` timestamp in TUI startup logs.
## Tests
- Existing tests in `status_command_tests.rs` are updated to match on
`RateLimitRefreshOrigin::StatusCommand { request_id }` instead of a bare
`request_id`.
- Focused `/status` tests now assert that status history avoids
transient refresh text, continues to request an async refresh, and uses
refreshed cached limits in future status output.
- No new tests are added for the startup prefetch path because it is a
fire-and-forget spawn with no observable side-effect other than the
widget state update, which is already covered by the
snapshot-application tests.

Fast Mode status was still tied to one model name in the TUI and
model-list plumbing. This changes the model metadata shape so a model
can advertise additional speed tiers, carries that field through the
app-server model list, and uses it to decide when to show Fast Mode
status.
For people using Codex, the behavior is intended to stay the same for
existing models. Fast Mode still requires the existing signed-in /
feature-gated path; the difference is that the UI can now recognize any
model the model list marks as Fast-capable, instead of requiring a new
client-side slug check.
Addresses #16421
Problem: Resumed interactive sessions exited before new token usage
skipped all footer lines, hiding the `codex resume` continuation
command.
It's not clear whether this was an intentional design choice, but I
think it's reasonable to expect this message under these circumstances.
Solution: Compose token usage and resume hints independently so
resumable sessions still print the continuation command with zero usage.
## Summary
- reduce public module visibility across Rust crates, preferring private
or crate-private modules with explicit crate-root public exports
- update external call sites and tests to use the intended public crate
APIs instead of reaching through module trees
- add the module visibility guideline to AGENTS.md
## Validation
- `cargo check --workspace --all-targets --message-format=short` passed
before the final fix/format pass
- `just fix` completed successfully
- `just fmt` completed successfully
- `git diff --check` passed
Addresses #16244
This was a performance regression introduced when we moved the TUI on
top of the app server API.
Problem: `/mcp` rebuilt a full MCP inventory through
`mcpServerStatus/list`, including resources and resource templates that
made the TUI wait on slow inventory probes.
Solution: add a lightweight `detail` mode to `mcpServerStatus/list`,
have `/mcp` request tools-and-auth only, and cover the fast path with
app-server and TUI tests.
Testing: Confirmed slow (multi-second) response prior to change and
immediate response after change.
I considered two options:
1. Change the existing `mcpServerStatus/list` API to accept an optional
"details" parameter so callers can request only a subset of the
information.
2. Add a separate `mcpServer/list` API that returns only the servers,
tools, and auth but omits the resources.
I chose option 1, but option 2 is also a reasonable approach.
Addresses #15282
Problem: Codex warned about missing system bubblewrap even when
sandboxing was disabled.
Solution: Gate the bwrap warning on the active sandbox policy and skip
it for danger-full-access and external-sandbox modes.
Stacked on #16508.
This removes the temporary `codex-core` / `codex-login` re-export shims
from the ownership split and rewrites callsites to import directly from
`codex-model-provider-info`, `codex-models-manager`, `codex-api`,
`codex-protocol`, `codex-feedback`, and `codex-response-debug-context`.
No behavior change intended; this is the mechanical import cleanup layer
split out from the ownership move.

Addresses #16560
Problem: `/status` stopped showing the source thread id in forked TUI
sessions after the app-server migration.
Solution: Carry fork source ids through app-server v2 thread data and
the TUI session adapter, and update TUI fixtures so `/status` matches
the old TUI behavior.
Addresses #16389
Problem: `/review` follow-ups can crash when app-server TUI steers with
a stale active turn id; #14717 introduced the client-side race, and
#15714 only handled the “no active turn” half.
Solution: Treat turn-id mismatch as stale cached state too, sync to the
server’s current turn id, retry once, and let review turns fall into the
existing queue path.
## Why
This finishes the config-type move out of `codex-core` by removing the
temporary compatibility shim in `codex_core::config::types`. Callers now
depend on `codex-config` directly, which keeps these config model types
owned by the config crate instead of re-expanding `codex-core` as a
transitive API surface.
## What Changed
- Removed the `codex-rs/core/src/config/types.rs` re-export shim and the
`core::config::ApprovalsReviewer` re-export.
- Updated `codex-core`, `codex-cli`, `codex-tui`, `codex-app-server`,
`codex-mcp-server`, and `codex-linux-sandbox` call sites to import
`codex_config::types` directly.
- Added explicit `codex-config` dependencies to downstream crates that
previously relied on the `codex-core` re-export.
- Regenerated `codex-rs/core/config.schema.json` after updating the
config docs path reference.
## Why
`codex-core` was re-exporting APIs owned by sibling `codex-*` crates,
which made downstream crates depend on `codex-core` as a proxy module
instead of the actual owner crate.
Removing those forwards makes crate boundaries explicit and lets leaf
crates drop unnecessary `codex-core` dependencies. In this PR, this
reduces the dependency on `codex-core` to `codex-login` in the following
files:
```
codex-rs/backend-client/Cargo.toml
codex-rs/mcp-server/tests/common/Cargo.toml
```
## What
- Remove `codex-rs/core/src/lib.rs` re-exports for symbols owned by
`codex-login`, `codex-mcp`, `codex-rollout`, `codex-analytics`,
`codex-protocol`, `codex-shell-command`, `codex-sandboxing`,
`codex-tools`, and `codex-utils-path`.
- Delete the `default_client` forwarding shim in `codex-rs/core`.
- Update in-crate and downstream callsites to import directly from the
owning `codex-*` crate.
- Add direct Cargo dependencies where callsites now target the owner
crate, and remove `codex-core` from `codex-rs/backend-client`.
Addresses #16283
Problem: TUI app-server permission approvals could drop filesystem
grants because request and response payloads were round-tripped through
mismatched camelCase and snake_case JSON shapes.
Solution: Replace the lossy JSON round-trips with typed app-server/core
permission conversions so requested and granted permission profiles,
including filesystem paths and scope, are preserved end to end.
Addresses a recent TUI regression
Problem: Pressing Ctrl+C during early TUI startup could route an
interrupt with no active turn into the generic unsupported-op fallback,
showing “Not available in app-server TUI yet for thread …” repeatedly.
Solution: Treat interrupt requests as handled when no active turn exists
yet, preventing fallback error spam during startup, and add a regression
test covering interrupt-without-active-turn behavior.
Fix stale weekly limit in `/status` (#16194): /status reused the
session’s cached rate-limit snapshot, so the weekly remaining limit
could stay frozen within an active session.
With this change, we now dynamically update the rate limits after status
is displayed.
I needed to delete a few low-value test cases from the chatWidget tests
because the test.rs file is really large, and the new tests in this PR
pushed us over the 512K mandated limit. I'm working on a separate PR to
refactor that test file.
The TUI’s `/feedback` flow was still uploading directly through the
local feedback crate, which bypassed app-server behavior such as
auth-derived feedback tags like chatgpt_user_id and made TUI feedback
handling diverge from other clients. It also meant that remove TUI
sessions failed to upload the correct feedback logs and session details.
Testing: Manually tested `/feedback` flow and confirmed that it didn't
regress.
Fixes#16092
The app-server-backed TUI could accumulate ghost subagent entries in
`/agent` after resume/backfill flows. Some of those rows were no longer
live according to the backend, but still appeared selectable in the
picker and could open as blank threads.
*Cause*
Unlike the legacy tui behavior, tui_app_server was creating local
picker/replay state for subagents discovered through metadata refresh
and loaded-thread backfill, even when no real local session or
transcript had been attached. That let stale ids survive in the picker
as if they were replayable threads.
*Fix*
Stop creating empty local thread channels during subagent metadata
hydration and loaded-thread backfill.
When opening /agent, prune metadata-only entries that thread/read
reports as terminally unavailable.
When selecting a discovered subagent that is still live but not yet
locally attached, materialize a real local session on demand from
thread/read instead of falling back to an empty replay state.
This is a follow-up to https://github.com/openai/codex/pull/15922. That
previous PR deleted the old `tui` directory and left the new
`tui_app_server` directory in place. This PR renames `tui_app_server` to
`tui` and fixes up all references.
This is the part 1 of 2 PRs that will delete the `tui` /
`tui_app_server` split. This part simply deletes the existing `tui`
directory and marks the `tui_app_server` feature flag as removed. I left
the `tui_app_server` feature flag in place for now so its presence
doesn't result in an error. It is simply ignored.
Part 2 will rename the `tui_app_server` directory `tui`. I did this as
two parts to reduce visible code churn.
## Why
This is effectively a follow-up to
[#15812](https://github.com/openai/codex/pull/15812). That change
removed the special skill-script exec path, but `skill_metadata` was
still being threaded through command-approval payloads even though the
approval flow no longer uses it to render prompts or resolve decisions.
Keeping it around added extra protocol, schema, and client surface area
without changing behavior.
Removing it keeps the command-approval contract smaller and avoids
carrying a dead field through app-server, TUI, and MCP boundaries.
## What changed
- removed `ExecApprovalRequestSkillMetadata` and the corresponding
`skillMetadata` field from core approval events and the v2 app-server
protocol
- removed the generated JSON and TypeScript schema output for that field
- updated app-server, MCP server, TUI, and TUI app-server approval
plumbing to stop forwarding the field
- cleaned up tests that previously constructed or asserted
`skillMetadata`
## Testing
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-protocol`
- `cargo test -p codex-app-server-test-client`
- `cargo test -p codex-mcp-server`
- `just argument-comment-lint`
Add environment manager that is a singleton and is created early in
app-server (before skill manager, before config loading).
Use an environment variable to point to a running exec server.
## Summary
- add `codex resume --include-non-interactive` to include
non-interactive sessions in the picker and `--last`
- keep current-provider and cwd filtering behavior unchanged
- replace the picker API boolean with a `SessionSourceFilter` enum to
avoid a boolean trap
## Tests
- `cargo test -p codex-cli`
- `cargo test -p codex-tui`
- `just fmt`
- `just fix -p codex-cli`
- `just fix -p codex-tui`
Migrate `cwd` and related session/config state to `AbsolutePathBuf` so
downstream consumers consistently see absolute working directories.
Add test-only `.abs()` helpers for `Path`, `PathBuf`, and `TempDir`, and
update branch-local tests to use them instead of
`AbsolutePathBuf::try_from(...)`.
For the remaining TUI/app-server snapshot coverage that renders absolute
cwd values, keep the snapshots unchanged and skip the Windows-only cases
where the platform-specific absolute path layout differs.
## Summary
- add `ForkSnapshotMode` to `ThreadManager::fork_thread` so callers can
request either a committed snapshot or an interrupted snapshot
- share the model-visible `<turn_aborted>` history marker between the
live interrupt path and interrupted forks
- update the small set of direct fork callsites to pass
`ForkSnapshotMode::Committed`
Note: this enables /btw to work similarly as Esc to interrupt (hopefully
somewhat in distribution)

## Why
Fixes [#15283](https://github.com/openai/codex/issues/15283), where
sandboxed tool calls fail on older distro `bubblewrap` builds because
`/usr/bin/bwrap` does not understand `--argv0`. The upstream [bubblewrap
v0.9.0 release
notes](https://github.com/containers/bubblewrap/releases/tag/v0.9.0)
explicitly call out `Add --argv0`. Flipping `use_legacy_landlock`
globally works around that compatibility bug, but it also weakens the
default Linux sandbox and breaks proxy-routed and split-policy cases
called out in review.
The follow-up Linux CI failure was in the new launcher test rather than
the launcher logic: the fake `bwrap` helper stayed open for writing, so
Linux would not exec it. This update also closes the user-visibility gap
from review by surfacing the same startup warning when `/usr/bin/bwrap`
is present but too old for `--argv0`, not only when it is missing.
## What Changed
- keep `use_legacy_landlock` default-disabled
- teach `codex-rs/linux-sandbox/src/launcher.rs` to fall back to the
vendored bubblewrap build when `/usr/bin/bwrap` does not advertise
`--argv0` support
- add launcher tests for supported, unsupported, and missing system
`bwrap`
- write the fake `bwrap` test helper to a closed temp path so the
supported-path launcher test works on Linux too
- extend the startup warning path so Codex warns when `/usr/bin/bwrap`
is missing or too old to support `--argv0`
- mirror the warning/fallback wording across
`codex-rs/linux-sandbox/README.md` and `codex-rs/core/README.md`,
including that the fallback is the vendored bubblewrap compiled into the
binary
- cite the upstream `bubblewrap` release that introduced `--argv0`
## Verification
- `bazel test --config=remote --platforms=//:rbe
//codex-rs/linux-sandbox:linux-sandbox-unit-tests
--test_filter=launcher::tests::prefers_system_bwrap_when_help_lists_argv0
--test_output=errors`

- `cargo check -p codex-exec -p codex-tui -p codex-tui-app-server -p

### Preliminary /plugins TUI menu
- Adds a preliminary /plugins menu flow in both tui and tui_app_server.
- Fetches plugin list data asynchronously and shows loading/error/cached
states.
- Limits this first pass to the curated ChatGPT marketplace.
- Shows available plugins with installed/status metadata.
- Supports in-menu search over plugin display name, plugin id, plugin
name, and marketplace label.
- Opens a plugin detail view on selection, including summaries for
Skills, Apps, and MCP Servers, with back navigation.
### Testing
- Launch codex-cli with plugins enabled (`--enable plugins`).
- Run /plugins and verify:
- loading state appears first
- plugin list is shown
- search filters results
- selecting a plugin opens detail view, with a list of
skills/connectors/MCP servers for the plugin
- back action returns to the list.
- Verify disabled behavior by running /plugins without plugins enabled
(shows “Plugins are disabled” message).
- Launch with `--enable tui_app_server` (and plugins enabled) and repeat
the same /plugins flow; behavior should match.
## Why
The argument-comment lint now has a packaged DotSlash artifact from
[#15198](https://github.com/openai/codex/pull/15198), so the normal repo
lint path should use that released payload instead of rebuilding the
lint from source every time.
That keeps `just clippy` and CI aligned with the shipped artifact while
preserving a separate source-build path for people actively hacking on
the lint crate.
The current alpha package also exposed two integration wrinkles that the
repo-side prebuilt wrapper needs to smooth over:
- the bundled Dylint library filename includes the host triple, for
example `@nightly-2025-09-18-aarch64-apple-darwin`, and Dylint derives
`RUSTUP_TOOLCHAIN` from that filename
- on Windows, Dylint's driver path also expects `RUSTUP_HOME` to be
present in the environment
Without those adjustments, the prebuilt CI jobs fail during `cargo
metadata` or driver setup. This change makes the checked-in prebuilt
wrapper normalize the packaged library name to the plain
`nightly-2025-09-18` channel before invoking `cargo-dylint`, and it
teaches both the wrapper and the packaged runner source to infer
`RUSTUP_HOME` from `rustup show home` when the environment does not
already provide it.
After the prebuilt Windows lint job started running successfully, it
also surfaced a handful of existing anonymous literal callsites in
`windows-sandbox-rs`. This PR now annotates those callsites so the new
cross-platform lint job is green on the current tree.
## What Changed
- checked in the current
`tools/argument-comment-lint/argument-comment-lint` DotSlash manifest
- kept `tools/argument-comment-lint/run.sh` as the source-build wrapper
for lint development
- added `tools/argument-comment-lint/run-prebuilt-linter.sh` as the
normal enforcement path, using the checked-in DotSlash package and
bundled `cargo-dylint`
- updated `just clippy` and `just argument-comment-lint` to use the
prebuilt wrapper
- split `.github/workflows/rust-ci.yml` so source-package checks live in
a dedicated `argument_comment_lint_package` job, while the released lint
runs in an `argument_comment_lint_prebuilt` matrix on Linux, macOS, and
Windows
- kept the pinned `nightly-2025-09-18` toolchain install in the prebuilt
CI matrix, since the prebuilt package still relies on rustup-provided
toolchain components
- updated `tools/argument-comment-lint/run-prebuilt-linter.sh` to
normalize host-qualified nightly library filenames, keep the `rustup`
shim directory ahead of direct toolchain `cargo` binaries, and export
`RUSTUP_HOME` when needed for Windows Dylint driver setup
- updated `tools/argument-comment-lint/src/bin/argument-comment-lint.rs`
so future published DotSlash artifacts apply the same nightly-filename
normalization and `RUSTUP_HOME` inference internally
- fixed the remaining Windows lint violations in
`codex-rs/windows-sandbox-rs` by adding the required `/*param*/`
comments at the reported callsites
- documented the checked-in DotSlash file, wrapper split, archive
layout, nightly prerequisite, and Windows `RUSTUP_HOME` requirement in
`tools/argument-comment-lint/README.md`
- Split the feature system into a new `codex-features` crate.
- Cut `codex-core` and workspace consumers over to the new config and
warning APIs.

## Problem
When multiple Codex sessions are open at once, terminal tabs and windows
are hard to distinguish from each other. The existing status line only
helps once the TUI is already focused, so it does not solve the "which
tab is this?" problem.
This PR adds a first-class `/title` command so the terminal window or
tab title can carry a short, configurable summary of the current
session.
## Screenshot
<img width="849" height="320" alt="image"
src="https://github.com/user-attachments/assets/8b112927-7890-45ed-bb1e-adf2f584663d"
/>
## Mental model
`/statusline` and `/title` are separate status surfaces with different
constraints. The status line is an in-app footer that can be denser and
more detailed. The terminal title is external terminal metadata, so it
needs short, stable segments that still make multiple sessions easy to
tell apart.
The `/title` configuration is an ordered list of compact items. By
default it renders `spinner,project`, so active sessions show
lightweight progress first while idle sessions still stay easy to
disambiguate. Each configured item is omitted when its value is not
currently available rather than forcing a placeholder.
## Non-goals
This does not merge `/title` into `/statusline`, and it does not add an
arbitrary free-form title string. The feature is intentionally limited
to a small set of structured items so the title stays short and
reviewable.
This also does not attempt to restore whatever title the terminal or
shell had before Codex started. When Codex clears the title, it clears
the title Codex last wrote.
## Tradeoffs
A separate `/title` command adds some conceptual overlap with
`/statusline`, but it keeps title-specific constraints explicit instead
of forcing the status line model to cover two different surfaces.
Title refresh can happen frequently, so the implementation now shares
parsing and git-branch orchestration between the status line and title
paths, and caches the derived project-root name by cwd. That keeps the
hot path cheap without introducing background polling.
## Architecture
The TUI gets a new `/title` slash command and a dedicated picker UI for
selecting and ordering terminal-title items. The chosen ids are
persisted in `tui.terminal_title`, with `spinner` and `project` as the
default when the config is unset. `status` remains available as a
separate text item, so configurations like `spinner,status` render
compact progress like `⠋ Working`.
`ChatWidget` now refreshes both status surfaces through a shared
`refresh_status_surfaces()` path. That shared path parses configured
items once, warns on invalid ids once, synchronizes shared cached state
such as git-branch lookup, then renders the footer status line and
terminal title from the same snapshot.
Low-level OSC title writes live in `codex-rs/tui/src/terminal_title.rs`,
which owns the terminal write path and last-mile sanitization before
emitting OSC 0.
## Security
Terminal-title text is treated as untrusted display content before Codex
emits it. The write path strips control characters, removes invisible
and bidi formatting characters that can make the title visually
misleading, normalizes whitespace, and caps the emitted length.

## Observability
Unknown configured title item ids are warned about once instead of
repeatedly spamming the transcript. Live preview applies immediately
while the `/title` picker is open, and cancel rolls the in-memory title
selection back to the pre-picker value.
If terminal title writes fail, the TUI emits debug logs around set and
clear attempts. The rendered status label intentionally collapses richer
internal states into compact title text such as `Starting...`, `Ready`,
`Thinking...`, `Working...`, `Waiting...`, and `Undoing...` when
`status` is configured.
## Tests
Ran:
- `just fmt`
- `cargo test -p codex-tui`
At the moment, the red Windows `rust-ci` failures are due to existing
`codex-core` `apply_patch_cli` stack-overflow tests that also reproduce
on `main`. The `/title`-specific `codex-tui` suite is green.
## Summary
- detect custom prompts in `$CODEX_HOME/prompts` during TUI startup
- show a deprecation notice only when prompts are present, with guidance
to use `$skill-creator`
- add TUI tests and snapshot coverage for present, missing, and empty
prompts directories
## Testing
- Manually tested
1. Use requirement-resolved config.features as the plugin gate.
2. Guard plugin/list, plugin/read, and related flows behind that gate.
3. Skip bad marketplace.json files instead of failing the whole list.
4. Simplify plugin state and caching.
## Problem
Ubuntu/AppArmor hosts started failing in the default Linux sandbox path
after the switch to vendored/default bubblewrap in `0.115.0`.
The clearest report is in
[#14919](https://github.com/openai/codex/issues/14919), especially [this
investigation
comment](https://github.com/openai/codex/issues/14919#issuecomment-4076504751):
on affected Ubuntu systems, `/usr/bin/bwrap` works, but a copied or
vendored `bwrap` binary fails with errors like `bwrap: setting up uid
map: Permission denied` or `bwrap: loopback: Failed RTM_NEWADDR:
Operation not permitted`.
The root cause is Ubuntu's `/etc/apparmor.d/bwrap-userns-restrict`
profile, which grants `userns` access specifically to `/usr/bin/bwrap`.
Once Codex started using a vendored/internal bubblewrap path, that path
was no longer covered by the distro AppArmor exception, so sandbox
namespace setup could fail even when user namespaces were otherwise
enabled and `uidmap` was installed.
## What this PR changes
- prefer system `/usr/bin/bwrap` whenever it is available
- keep vendored bubblewrap as the fallback when `/usr/bin/bwrap` is
missing
- when `/usr/bin/bwrap` is missing, surface a Codex startup warning
through the app-server/TUI warning path instead of printing directly
from the sandbox helper with `eprintln!`
- use the same launcher decision for both the main sandbox execution
path and the `/proc` preflight path
- document the updated Linux bubblewrap behavior in the Linux sandbox
and core READMEs
## Why this fix
This still fixes the Ubuntu/AppArmor regression from
[#14919](https://github.com/openai/codex/issues/14919), but it keeps the
runtime rule simple and platform-agnostic: if the standard system
bubblewrap is installed, use it; otherwise fall back to the vendored
helper.
The warning now follows that same simple rule. If Codex cannot find
`/usr/bin/bwrap`, it tells the user that it is falling back to the
vendored helper, and it does so through the existing startup warning
plumbing that reaches the TUI and app-server instead of low-level
sandbox stderr.

PR https://github.com/openai/codex/pull/14512 added an in-process app
server and started to wire up the tui to use it. We were originally
planning to modify the `tui` code in place, converting it to use the app
server a bit at a time using a hybrid adapter. We've since decided to
create an entirely new parallel `tui_app_server` implementation and do
the conversion all at once but retain the existing `tui` while we work
the bugs out of the new implementation.
This PR undoes the changes to the `tui` made in the PR #14512 and
restores the old initialization to its previous state. This allows us to
modify the `tui_app_server` without the risk of regressing the old `tui`
code. For example, we can start to remove support for all legacy core
events, like the ones that PR https://github.com/openai/codex/pull/14892
needed to ignore.
Testing:
* I manually verified that the old `tui` starts and shuts down without a
problem.
## Why
Once the repo-local lint exists, `codex-rs` needs to follow the
checked-in convention and CI needs to keep it from drifting. This commit
applies the fallback `/*param*/` style consistently across existing
positional literal call sites without changing those APIs.
The longer-term preference is still to avoid APIs that require comments
by choosing clearer parameter types and call shapes. This PR is
intentionally the mechanical follow-through for the places where the
existing signatures stay in place.
After rebasing onto newer `main`, the rollout also had to cover newly
introduced `tui_app_server` call sites. That made it clear the first cut
of the CI job was too expensive for the common path: it was spending
almost as much time installing `cargo-dylint` and re-testing the lint
crate as a representative test job spends running product tests. The CI
update keeps the full workspace enforcement but trims that extra
overhead from ordinary `codex-rs` PRs.
## What changed
- keep a dedicated `argument_comment_lint` job in `rust-ci`
- mechanically annotate remaining opaque positional literals across
`codex-rs` with exact `/*param*/` comments, including the rebased
`tui_app_server` call sites that now fall under the lint
- keep the checked-in style aligned with the lint policy by using
`/*param*/` and leaving string and char literals uncommented
- cache `cargo-dylint`, `dylint-link`, and the relevant Cargo
registry/git metadata in the lint job
- split changed-path detection so the lint crate's own `cargo test` step
runs only when `tools/argument-comment-lint/*` or `rust-ci.yml` changes
- continue to run the repo wrapper over the `codex-rs` workspace, so
product-code enforcement is unchanged
Most of the code changes in this commit are intentionally mechanical
comment rewrites or insertions driven by the lint itself.
## Verification
- `./tools/argument-comment-lint/run.sh --workspace`
- `cargo test -p codex-tui-app-server -p codex-tui`
- parsed `.github/workflows/rust-ci.yml` locally with PyYAML

## Summary
- reuse a guardian subagent session across approvals so reviews keep a
stable prompt cache key and avoid one-shot startup overhead
- clear the guardian child history before each review so prior guardian
decisions do not leak into later approvals
- include the `smart_approvals` -> `guardian_approval` feature flag
rename in the same PR to minimize release latency on a very tight
timeline
- add regression coverage for prompt-cache-key reuse without
prior-review prompt bleed

## Summary
- add `approvals_reviewer = "user" | "guardian_subagent"` as the runtime
control for who reviews approval requests
- route Smart Approvals guardian review through core for command
execution, file changes, managed-network approvals, MCP approvals, and
delegated/subagent approval flows
- expose guardian review in app-server with temporary unstable
`item/autoApprovalReview/{started,completed}` notifications carrying
`targetItemId`, `review`, and `action`
- update the TUI so Smart Approvals can be enabled from `/experimental`,
aligned with the matching `/approvals` mode, and surfaced clearly while
reviews are pending or resolved
## Runtime model
This PR does not introduce a new `approval_policy`.
Instead:
- `approval_policy` still controls when approval is needed
- `approvals_reviewer` controls who reviewable approval requests are
routed to:
- `user`
- `guardian_subagent`
`guardian_subagent` is a carefully prompted reviewer subagent that
gathers relevant context and applies a risk-based decision framework
before approving or denying the request.
The `smart_approvals` feature flag is a rollout/UI gate. Core runtime
behavior keys off `approvals_reviewer`.
When Smart Approvals is enabled from the TUI, it also switches the
current `/approvals` settings to the matching Smart Approvals mode so
users immediately see guardian review in the active thread:
- `approval_policy = on-request`
- `approvals_reviewer = guardian_subagent`
- `sandbox_mode = workspace-write`
Users can still change `/approvals` afterward.
Config-load behavior stays intentionally narrow:
- plain `smart_approvals = true` in `config.toml` remains just the
rollout/UI gate and does not auto-set `approvals_reviewer`
- the deprecated `guardian_approval = true` alias migration does
backfill `approvals_reviewer = "guardian_subagent"` in the same scope
when that reviewer is not already configured there, so old configs
preserve their original guardian-enabled behavior
ARC remains a separate safety check. For MCP tool approvals, ARC
escalations now flow into the configured reviewer instead of always
bypassing guardian and forcing manual review.
## Config stability
The runtime reviewer override is stable, but the config-backed
app-server protocol shape is still settling.
- `thread/start`, `thread/resume`, and `turn/start` keep stable
`approvalsReviewer` overrides
- the config-backed `approvals_reviewer` exposure returned via
`config/read` (including profile-level config) is now marked
`[UNSTABLE]` / experimental in the app-server protocol until we are more
confident in that config surface
## App-server surface
This PR intentionally keeps the guardian app-server shape narrow and
temporary.
It adds generic unstable lifecycle notifications:
- `item/autoApprovalReview/started`
- `item/autoApprovalReview/completed`
with payloads of the form:
- `{ threadId, turnId, targetItemId, review, action? }`
`review` is currently:
- `{ status, riskScore?, riskLevel?, rationale? }`
- where `status` is one of `inProgress`, `approved`, `denied`, or
`aborted`
`action` carries the guardian action summary payload from core when
available. This lets clients render temporary standalone pending-review
UI, including parallel reviews, even when the underlying tool item has
not been emitted yet.
These notifications are explicitly documented as `[UNSTABLE]` and
expected to change soon.
This PR does **not** persist guardian review state onto `thread/read`
tool items. The intended follow-up is to attach guardian review state to
the reviewed tool item lifecycle instead, which would improve
consistency with manual approvals and allow thread history / reconnect
flows to replay guardian review state directly.
## TUI behavior
- `/experimental` exposes the rollout gate as `Smart Approvals`
- enabling it in the TUI enables the feature and switches the current
session to the matching Smart Approvals `/approvals` mode
- disabling it in the TUI clears the persisted `approvals_reviewer`
override when appropriate and returns the session to default manual
review when the effective reviewer changes
- `/approvals` still exposes the reviewer choice directly
- the TUI renders:
- pending guardian review state in the live status footer, including
parallel review aggregation
- resolved approval/denial state in history
## Scope notes
This PR includes the supporting core/runtime work needed to make Smart
Approvals usable end-to-end:
- shell / unified-exec / apply_patch / managed-network / MCP guardian
review
- delegated/subagent approval routing into guardian review
- guardian review risk metadata and action summaries for app-server/TUI
- config/profile/TUI handling for `smart_approvals`, `guardian_approval`
alias migration, and `approvals_reviewer`
- a small internal cleanup of delegated approval forwarding to dedupe
fallback paths and simplify guardian-vs-parent approval waiting (no
intended behavior change)
Out of scope for this PR:
- redesigning the existing manual approval protocol shapes
- persisting guardian review state onto app-server `ThreadItem`s
- delegated MCP elicitation auto-review (the current delegated MCP
guardian shim only covers the legacy `RequestUserInput` path)
