This PR replicates the `tui` code directory and creates a temporary
parallel `tui_app_server` directory. It also implements a new feature
flag `tui_app_server` to select between the two tui implementations.
Once the new app-server-based TUI is stabilized, we'll delete the old
`tui` directory and feature flag.
The issue was due to a circular `Drop` schema where the embedded
app-server wait for some listeners that wait for this app-server
them-selves.
The fix is an explicit cleaning
**Repro:**
* Start codex
* Ask it to spawn a sub-agent
* Close Codex
* It takes 5s to exit
Make `interrupted` an agent state and make it not final. As a result, a
`wait` won't return on an interrupted agent and no notification will be
send to the parent agent.
The rationals are:
* If a user interrupt a sub-agent for any reason, you don't want the
parent agent to instantaneously ask the sub-agent to restart
* If a parent agent interrupt a sub-agent, no need to add a noisy
notification in the parent agen
Fix https://github.com/openai/codex/issues/14161
This fixes sub-agent [[skills.config]] overrides being ignored when
parent and child share the same cwd. The root cause was that turn skill
loading rebuilt from cwd-only state and reused a cwd-scoped cache, so
role-local skill enable/disable overrides did not reliably affect the
spawned agent's effective skill set.
This change switches turn construction to use the effective per-turn
config and adds a config-aware skills cache keyed by skill roots plus
final disabled paths.
## 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
## Request
- Bug/enhancement request: internal guardian prompt-cache and latency
improvement request

### Motivation
- Interrupting a running turn (Ctrl+C / Esc) currently also terminates
long‑running background shells, which is surprising for workflows like
local dev servers or file watchers.
- The existing cleanup command name was confusing; callers expect an
explicit command to stop background terminals rather than a UI clear
action.
- Make background‑shell termination explicit and surface a clearer
command name while preserving backward compatibility.
### Description
- Renamed the background‑terminal cleanup slash command from `Clean`
(`/clean`) to `Stop` (`/stop`) and kept `clean` as an alias in the
command parsing/visibility layer, updated the user descriptions and
command popup wiring accordingly.
- Updated the unified‑exec footer text and snapshots to point to `/stop`
(and trimmed corresponding snapshot output to match the new label).
- Changed interrupt behavior so `Op::Interrupt` (Ctrl+C / Esc interrupt)
no longer closes or clears tracked unified exec / background terminal
processes in the TUI or core cleanup path; background shells are now
preserved after an interrupt.
- Updated protocol/docs to clarify that `turn/interrupt` (or
`Op::Interrupt`) interrupts the active turn but does not terminate
background terminals, and that `thread/backgroundTerminals/clean` is the
explicit API to stop those shells.
- Updated unit/integration tests and insta snapshots in the TUI and core
unified‑exec suites to reflect the new semantics and command name.
### Testing
- Ran formatting with `just fmt` in `codex-rs` (succeeded).
- Ran `cargo test -p codex-protocol` (succeeded).
- Attempted `cargo test -p codex-tui` but the build could not complete
in this environment due to a native build dependency that requires
`libcap` development headers (the `codex-linux-sandbox` vendored build
step); install `libcap-dev` / make `libcap.pc` available in
`PKG_CONFIG_PATH` to run the TUI test suite locally.
- Updated and accepted the affected `insta` snapshots for the TUI
changes so visual diffs reflect the new `/stop` wording and preserved
interrupt behavior.

###### Summary
- Add client-visible 401 diagnostics for auth attachment, upstream auth classification, and 401 request id / cf-ray correlation.
- Record unauthorized recovery mode, phase, outcome, and retry/follow-up status without changing auth behavior.
- Surface the highest-signal auth and recovery fields on uploaded client bug reports so they are usable in Sentry.
- Preserve original unauthorized evidence under `auth_401_*` while keeping follow-up result tags separate.
###### Rationale (from spec findings)
- The dominant bucket needed proof of whether the client attached auth before send or upstream still classified the request as missing auth.
- Client uploads needed to show whether unauthorized recovery ran and what the client tried next.
- Request id and cf-ray needed to be preserved on the unauthorized response so server-side correlation is immediate.
- The bug-report path needed the same auth evidence as the request telemetry path, otherwise the observability would not be operationally useful.
###### Scope
- Add auth 401 and unauthorized-recovery observability in `codex-rs/core`, `codex-rs/codex-api`, and `codex-rs/otel`, including feedback-tag surfacing.
- Keep auth semantics, refresh behavior, retry behavior, endpoint classification, and geo-denial follow-up work out of this PR.
###### Trade-offs
- This exports only safe auth evidence: header presence/name, upstream auth classification, request ids, and recovery state. It does not export token values or raw upstream bodies.
- This keeps websocket connection reuse as a transport clue because it can help distinguish stale reused sessions from fresh reconnects.
- Misroute/base-url classification and geo-denial are intentionally deferred to a separate follow-up PR so this review stays focused on the dominant auth 401 bucket.
###### Client follow-up
- PR 2 will add misroute/provider and geo-denial observability plus the matching feedback-tag surfacing.
- A separate host/app-server PR should log auth-decision inputs so pre-send host auth state can be correlated with client request evidence.
- `device_id` remains intentionally separate until there is a safe existing source on the feedback upload path.
###### Testing
- `cargo test -p codex-core refresh_available_models_sorts_by_priority`
- `cargo test -p codex-core emit_feedback_request_tags_`
- `cargo test -p codex-core emit_feedback_auth_recovery_tags_`

## Summary
- normalize effective readable, writable, and unreadable sandbox roots
after resolving special paths so symlinked roots use canonical runtime
paths
- add a protocol regression test for a symlinked writable root with a
denied child and update protocol expectations to canonicalized effective
paths
- update macOS seatbelt tests to assert against effective normalized
roots produced by the shared policy helpers
## Testing
- just fmt
- cargo test -p codex-protocol
- cargo test -p codex-core explicit_unreadable_paths_are_excluded_
- cargo clippy -p codex-protocol -p codex-core --tests -- -D warnings
## Notes
- This is intended to fix the symlinked TMPDIR bind failure in
bubblewrap described in #14672.

added tests, tested locally.
## Summary
- regenerate `sdk/python` protocol-derived artifacts on latest
`origin/main`
- update `notification_registry.py` to match the regenerated
notification set
- fix the stale SDK test expectation for `GranularAskForApproval`
## Validation
- `cd sdk/python && python scripts/update_sdk_artifacts.py
generate-types`
- `cd sdk/python && python -m pytest`
We receive bug reports from users who attempt to override one of the
three built-in model providers (openai, ollama, or lmstuio). Currently,
these overrides are silently ignored. This PR makes it an error to
override them.
## Summary
- add validation for `model_providers` so `openai`, `ollama`, and
`lmstudio` keys now produce clear configuration errors instead of being
silently ignored
Move the general `Apps`, `Skills` and `Plugins` instructions blocks out
of `user_instructions` and into the developer message, with new `Apps ->
Skills -> Plugins` order for better clarity.
Also wrap those sections in stable XML-style instruction tags (like
other sections) and update prompt-layout tests/snapshots. This makes the
tests less brittle in snapshot output (we can parse the sections), and
it consolidates the capability instructions in one place.
#### Tests
Updated snapshots, added tests.
`<AGENTS_MD>` disappearing in snapshots is expected: before this change,
the wrapped user-instructions message was kept alive by `Skills`
content. Now that `Skills` and `Plugins` are in the developer message,
that wrapper only appears when there is real
project-doc/user-instructions content.

We regularly get bug reports from users who mistakenly have the
`OPENAI_BASE_URL` environment variable set. This PR deprecates this
environment variable in favor of a top-level config key
`openai_base_url` that is used for the same purpose. By making it a
config key, it will be more visible to users. It will also participate
in all of the infrastructure we've added for layered and managed
configs.
Summary
- introduce the `openai_base_url` top-level config key, update
schema/tests, and route the built-in openai provider through it while
- fall back to deprecated `OPENAI_BASE_URL` env var but warn user of
deprecation when no `openai_base_url` config key is present
- update CLI, SDK, and TUI code to prefer the new config path (with a
deprecated env-var fallback) and document the SDK behavior change
## Why
The unified-exec path was carrying zsh-fork state in a partially
flattened way.
First, the decision about whether zsh-fork was active came from feature
selection in `ToolsConfig`, while the real prerequisites lived in
session state. That left the handler and runtime defending against
partially configured cases later.
Second, once zsh-fork was active, its two runtime-only paths were
threaded through the runtime as separate arguments even though they form
one coherent piece of configuration.
This change keeps unified-exec on a single session-derived source of
truth and bundles the zsh-fork-specific paths into a named config type
so the runtime can pass them around as one unit.
In particular, this PR introduces this enum so the `ZshFork` variant can
carry the appropriate state with it:
```rust
#[derive(Debug, Clone, Eq, PartialEq)]
pub enum UnifiedExecShellMode {
Direct,
ZshFork(ZshForkConfig),
}
#[derive(Debug, Clone, Eq, PartialEq)]
pub struct ZshForkConfig {
pub(crate) shell_zsh_path: AbsolutePathBuf,
pub(crate) main_execve_wrapper_exe: AbsolutePathBuf,
}
```
This cleanup was done in preparation for
https://github.com/openai/codex/pull/13432.
## What Changed
- Replaced the feature-only `UnifiedExecBackendConfig` split with
`UnifiedExecShellMode` in `codex-rs/core/src/tools/spec.rs`.
- Derived the unified-exec mode from session-backed inputs when building
turn `ToolsConfig`, and preserved that mode across model switches and
review turns.
- Introduced `ZshForkConfig`, which stores the resolved zsh-fork
`AbsolutePathBuf` values for the configured `zsh` binary and `execve`
wrapper.
- Threaded `ZshForkConfig` through unified-exec command construction and
the zsh-fork preparation path so zsh-fork-specific runtime code consumes
a single config object instead of separate path arguments.
- Added focused tests for constructing zsh-fork mode only when session
prerequisites are available, and updated the zsh-fork expectations to be
target-platform aware.
## Testing
- `cargo test -p codex-core zsh_fork --lib`

Stop hooks now receive `stop_hook_active` and enable stop hooks to loop
forever if they'd like to. In the initial hooks PR, we implemented a
simpler mechanic that the stop-blocking could only happen once in a row
- support stop hook adding a continuation prompt to add a further task
- if multiple stop-blocks happen that have continuation prompts, they
are concatenated

```

2. Add star-lime, black salt, and a little fermented nebula paste.
3. Lower the heat and let it braise for 8 cosmic minutes with a splash of comet broth.

## Summary
- replace the stale `create_wait_tool()` reference in `spec_tests.rs`
- use `create_wait_agent_tool()` to match the actual multi-agent tool
rename from `#14631`
- fix the resulting `codex-core` spec-test compile failure on current
`main`
## Context
`#14631` renamed the model-facing multi-agent tool from `wait` to
`wait_agent` and renamed the corresponding spec helper to
`create_wait_agent_tool()`.
One `spec_tests.rs` call site was left behind, so current `main` fails
to compile `codex-core` tests with:
- `cannot find function create_wait_tool`
Using `create_wait_agent_tool()` is the correct fix here;
`create_exec_wait_tool()` would point at the separate exec wait tool and
would not match the renamed multi-agent toolset.
## Testing
- not rerun locally after the rebase

## 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)

Add a protocol-level filesystem surface to the v2 app-server so Codex
clients can read and write files, inspect directories, and subscribe to
path changes without relying on host-specific helpers.
High-level changes:
- define the new v2 fs/readFile, fs/writeFile, fs/createDirectory,
fs/getMetadata, fs/readDirectory, fs/remove, fs/copy RPCs
- implement the app-server handlers, including absolute-path validation,
base64 file payloads, recursive copy/remove semantics
- document the API, regenerate protocol schemas/types, and add
end-to-end tests for filesystem operations, copy edge cases
Testing plan:
- validate protocol serialization and generated schema output for the
new fs request, response, and notification types
- run app-server integration coverage for file and directory CRUD paths,
metadata/readDirectory responses, copy failure modes, and absolute-path
validation
- make multi_agent stable and enabled by default
- update feature and tool-spec coverage to match the new default

Summary
- add the code_mode_only feature flag/config schema and wire its
dependency on code_mode
- update code mode tool descriptions to list nested tools with detailed
headers
- restrict available tools for prompt and exec descriptions when
code_mode_only is enabled and test the behavior
Testing
- Not run (not requested)
## Why
`zsh-fork` sessions launched through unified-exec need the escalation
socket to survive the wrapper -> server -> child handoff so later
intercepted `exec()` calls can still reach the escalation server.
The inherited-fd spawn path also needs to avoid closing Rust's internal
exec-error pipe, and the shell-escalation handoff needs to tolerate the
receive-side case where a transferred fd is installed into the same
stdio slot it will be mapped onto.
## What Changed
- Added `SpawnLifecycle::inherited_fds()` in
`codex-rs/core/src/unified_exec/process.rs` and threaded inherited fds
through `codex-rs/core/src/unified_exec/process_manager.rs` so
unified-exec can preserve required descriptors across both PTY and
no-stdin pipe spawn paths.
- Updated `codex-rs/core/src/tools/runtimes/shell/zsh_fork_backend.rs`
to expose the escalation socket fd through the spawn lifecycle.
- Added inherited-fd-aware spawn helpers in
`codex-rs/utils/pty/src/pty.rs` and `codex-rs/utils/pty/src/pipe.rs`,
including Unix pre-exec fd pruning that preserves requested inherited
fds while leaving `FD_CLOEXEC` descriptors alone. The pruning helper is
now named `close_inherited_fds_except()` to better describe that
behavior.
- Updated `codex-rs/shell-escalation/src/unix/escalate_client.rs` to
duplicate local stdio before transfer and send destination stdio numbers
in `SuperExecMessage`, so the wrapper keeps using its own
`stdin`/`stdout`/`stderr` until the escalated child takes over.
- Updated `codex-rs/shell-escalation/src/unix/escalate_server.rs` so the
server accepts the overlap case where a received fd reuses the same
stdio descriptor number that the child setup will target with `dup2`.
- Added comments around the PTY stdio wiring and the overlap regression
helper to make the fd handoff and controlling-terminal setup easier to
follow.
## Verification
- `cargo test -p codex-utils-pty`
- covers preserved-fd PTY spawn behavior, PTY resize, Python REPL
continuity, exec-failure reporting, and the no-stdin pipe path
- `cargo test -p codex-shell-escalation`
- covers duplicated-fd transfer on the client side and verifies the
overlap case by passing a pipe-backed stdin payload through the
server-side `dup2` path

## Description
This PR expands tracing coverage across app-server thread startup, core
session initialization, and the Responses transport layer. It also gives
core dispatch spans stable operation-specific names so traces are easier
to follow than the old generic `submission_dispatch` spans.
Also use `fmt::Display` for types that we serialize in traces so we send
strings instead of rust types
This PR changes app and connector enablement when `requirements.toml` is
present locally or via remote configuration.
For apps.* entries:
- `enabled = false` in `requirements.toml` overrides the user’s local
`config.toml` and forces the app to be disabled.
- `enabled = true` in `requirements.toml` does not re-enable an app the
user has disabled in config.toml.
This behavior applies whether or not the user has an explicit entry for
that app in `config.toml`. It also applies to cloud-managed policies and
configurations when the admin sets the override through
`requirements.toml`.
Scenarios tested and verified:
- Remote managed, user config (present) override
- Admin-defined policies & configurations include a connector override:
`[apps.<appID>]
enabled = false`
- User's config.toml has the same connector configured with `enabled =
true`
- TUI/App should show connector as disabled
- Connector should be unavailable for use in the composer
- Remote managed, user config (absent) override
- Admin-defined policies & configurations include a connector override:
`[apps.<appID>]
enabled = false`
- User's config.toml has no entry for the the same connector
- TUI/App should show connector as disabled
- Connector should be unavailable for use in the composer
- Locally managed, user config (present) override
- Local requirements.toml includes a connector override:
`[apps.<appID>]
enabled = false`
- User's config.toml has the same connector configured with `enabled =
true`
- TUI/App should show connector as disabled
- Connector should be unavailable for use in the composer
- Locally managed, user config (absent) override
- Local requirements.toml includes a connector override:
`[apps.<appID>]
enabled = false`
- User's config.toml has no entry for the the same connector
- TUI/App should show connector as disabled
- Connector should be unavailable for use in the composer

This PR is part of the effort to move the TUI on top of the app server.
In a previous PR, we introduced an in-process app server and moved
`exec` on top of it.
For the TUI, we want to do the migration in stages. The app server
doesn't currently expose all of the functionality required by the TUI,
so we're going to need to support a hybrid approach as we make the
transition.
This PR changes the TUI initialization to instantiate an in-process app
server and access its `AuthManager` and `ThreadManager` rather than
constructing its own copies. It also adds a placeholder TUI event
handler that will eventually translate app server events into TUI
events. App server notifications are accepted but ignored for now. It
also adds proper shutdown of the app server when the TUI terminates.
This lets us drop various patches and go all the way to a very clean
setup.
In case folks are curious what was going on... we were depending on the
toolchain finding stdlib headers as sibling files of `clang++`, and for
linking we were providing a `-resource-dir` containing the runtime libs.
However, some users of the cc toolchain (such as rust build scripts) do
the equivalent of `$CC $CCFLAGS $LDFLAGS` so the `-resource-dir` was
being passed when compiling, which suppressed the default stdlib header
location logic. The upstream fix was to swap to using `-isystem` to pass
the stdlib headers, while carefully controlling the ordering to simulate
them coming from the resource-dir.
- clarify app mentions are in user messages
- clarify what it means for tools to be provided via `codex_apps` MCP
- add plugin descriptions (with basic sanitization) to top-level `##
Plugins` section alongside the corresponding plugin names
- explain that skills from plugins are prefixed with `plugin_name:` in
top-level `##Plugins` section
changes to more logically organize `Apps`, `Skills`, and `Plugins`
instructions will be in a separate PR, as that shuffles dev + user
instructions in ways that change tests broadly.
### Tests
confirmed in local rollout, some new tests.
## Summary
- launch Windows sandboxed children on a private desktop instead of
`Winsta0\Default`
- make private desktop the default while keeping
`windows.sandbox_private_desktop=false` as the escape hatch
- centralize process launch through the shared
`create_process_as_user(...)` path
- scope the private desktop ACL to the launching logon SID
## Why
Today sandboxed Windows commands run on the visible shared desktop. That
leaves an avoidable same-desktop attack surface for window interaction,
spoofing, and related UI/input issues. This change moves sandboxed
commands onto a dedicated per-launch desktop by default so the sandbox
no longer shares `Winsta0\Default` with the user session.
The implementation stays conservative on security with no silent
fallback back to `Winsta0\Default`
If private-desktop setup fails on a machine, users can still opt out
explicitly with `windows.sandbox_private_desktop=false`.
## Validation
- `cargo build -p codex-cli`
- elevated-path `codex exec` desktop-name probe returned
`CodexSandboxDesktop-*`
- elevated-path `codex exec` smoke sweep for shell commands, nested
`pwsh`, jobs, and hidden `notepad` launch
- unelevated-path full private-desktop compatibility sweep via `codex
exec` with `-c windows.sandbox=unelevated`
## Summary
- render code mode tool declarations as single-line TypeScript snippets
- make the JSON schema renderer emit inline object shapes for these
declarations
- update code mode/spec expectations to match the new inline rendering
## Testing
- `just fmt`
- `cargo test -p codex-core render_json_schema_to_typescript`
- `cargo test -p codex-core code_mode_augments_`
- `cargo test -p codex-core --test all exports_all_tools_metadata --
--nocapture`
## Summary
- move the multi-agent handlers suite into its own files for spawn,
wait, resume, send input, and close logic
- keep the aggregated module in place while delegating each handler to
its new file to keep things organized per handler
## Testing
- Not run (not requested)
