- [x] Add mentions of connectors because model always think in connector
terms in its CoT.
- [x] Suppress list_mcp_resources in favor of tool search for available
apps.
- Update the code-mode executor, wait handler, and protocol plumbing to
use cell IDs instead of session IDs for node communication
- Switch tool metadata, wait description, and suite tests to refer to
cell IDs so user-visible messages match the new terminology

## Summary
- update `codex-rs/core/templates/memories/stage_one_system.md` so phase
1 captures stronger user-preference signals, richer task summaries, and
cwd provenance without branch-specific fields
- update `codex-rs/core/templates/memories/consolidation.md` so phase 2
keeps separate sections for user preferences, reusable knowledge, and
failure shields while staying cwd-aware but branchless
- document the `codex` prompt-template maintenance rule in
`codex-rs/core/src/memories/README.md`: the undated templates are
canonical here and should be edited in place
## Testing
- cargo test -p codex-core memories --manifest-path codex-rs/Cargo.toml
**Summary**
- disable the `code_mode_nested_tool_calls_can_run_in_parallel` test on
Windows where `exec_command` is unavailable

## Summary
Dynamic tool responses containing literal U+2028 / U+2029 would cause
await codex.tool(...) to hang even though the response had already
arrived. This PR replaces the kernel’s readline-based stdin handling
with byte-oriented JSONL framing that handles these characters properly.
## Testing
- `cargo test -p codex-core`
- tested the binary on a repro case and confirmed it's fixed

## Summary
- create the turn-scoped `ToolCallRuntime` before starting the code mode
worker so the worker reuses the same runtime and router
- thread the shared runtime through the code mode service/worker path
and use it for nested tool calls
- model aborted tool calls as a concrete `ToolOutput` so aborted
responses still produce valid tool output shapes
## Testing
- `just fmt`
- `cargo test -p codex-core` (still running locally)
This makes the test less flaky by checking the core invariant instead of
the full span chain.
Before, the test waited for several specific internal spans
(`submission_dispatch`, `session_task.turn`, `run_turn`) and asserted
their exact relationships. That was brittle because those spans are
exported asynchronously and are more of an implementation detail than
the thing we actually care about.
Now, the test only checks that:
- `turn/start` is on the expected remote trace with the expected remote
parent
- at least one representative core turn span on that same trace descends
from it
That keeps the sanity-check we want while making the test less sensitive
to timing and internal refactors.
Summary
- pin tests to `test-gpt-5.1-codex` so code-mode suites exercise that
model explicitly
- add a regression test that ensures nested tool calls can execute in
parallel and assert on timing
- refresh `codex-rs/Cargo.lock` for the updated dependency tree (add
`codex-utils-pty`, drop `codex-otel`)
Testing
- Not run (not requested)
Summary
- expose the default yield timeout through code mode runtime so the
handler, wait tool, and protocol share the same 10s value that matches
unified exec
- document the timeout change in the tool descriptions and propagate the
value all the way into the runner metadata
- adjust Cargo.lock to keep the dependency tree in sync with the added
code mode tool dependency

Fixes [#8889](https://github.com/openai/codex/issues/8889).
## Summary
- Discover and use advertised MCP OAuth `scopes_supported` when no
explicit or configured scopes are present.
- Apply the same scope precedence across `mcp add`, `mcp login`, skill
dependency auto-login, and app-server MCP OAuth login.
- Keep discovered scopes ephemeral and non-persistent.
- Retry once without scopes for CLI and skill auto-login flows if the
OAuth provider rejects discovered scopes.
## Motivation
Some MCP servers advertise the scopes they expect clients to request
during OAuth, but Codex was ignoring that metadata and typically
starting OAuth with no scopes unless the user manually passed `--scopes`
or configured `server.scopes`.
That made compliant MCP servers harder to use out of the box and is the
behavior described in
[#8889](https://github.com/openai/codex/issues/8889).
This change also brings our behavior in line with the MCP authorization
spec's scope selection guidance:
https://modelcontextprotocol.io/specification/2025-11-25/basic/authorization#scope-selection-strategy
## Behavior
Scope selection now follows this order everywhere:
1. Explicit request scopes / CLI `--scopes`
2. Configured `server.scopes`
3. Discovered `scopes_supported`
4. Legacy empty-scope behavior
Compatibility notes:
- Existing working setups keep the same behavior because explicit and
configured scopes still win.
- Discovered scopes are never written back into config or token storage.
- If discovery is missing, malformed, or empty, behavior falls back to
the previous empty-scope path.
- App-server login gets the same precedence rules, but does not add a
transparent retry path in this change.
## Implementation
- Extend streamable HTTP OAuth discovery to parse and normalize
`scopes_supported`.
- Add a shared MCP scope resolver in `core` so all login entrypoints use
the same precedence rules.
- Preserve provider callback errors from the OAuth flow so CLI/skill
flows can safely distinguish provider rejections from other failures.
- Reuse discovered scopes from the existing OAuth support check where
possible instead of persisting new config.
as reported in https://github.com/openai/codex/issues/14367 users can
explicitly enable unified_exec which will bypass the sandbox even when
it should be enabled.
Until we support unified_exec with the Windows Sandbox, we will disallow
it unless the sandbox is disabled
## Stack
fix: fail closed for unsupported split windows sandboxing #14172
-> fix: preserve split filesystem semantics in linux sandbox #14173
fix: align core approvals with split sandbox policies #14171
refactor: centralize filesystem permissions precedence #14174
## Summary
## Summary
- Preserve Linux split filesystem carveouts in bubblewrap by applying
mount masks in the right order, so narrower rules still win under
broader writable roots.
- Preserve unreadable ancestors of writable roots by masking them first
and then rebinding the narrower writable descendants.
- Stop rejecting legacy-plus-split Linux configs that are
sandbox-equivalent after `cwd` resolution by comparing semantics instead
of raw legacy structs.
- Fail closed when callers provide partial split policies, mismatched
legacy-plus-split policies, or force `--use-legacy-landlock` for
split-only shapes that legacy Landlock cannot enforce.
- Add Linux regressions for overlapping writable, read-only, and denied
paths, and document the supported split-policy enforcement path.
## Example
Given a split filesystem policy like:
```toml
[permissions.dev.filesystem]
":root" = "read"
"/code" = "write"
"/code/.git" = "read"
"/code/secrets" = "none"
"/code/secrets/tmp" = "write"
```
this PR makes Linux enforce the intended result under bubblewrap:
- `/code` stays writable
- `/code/.git` stays read-only
- `/code/secrets` stays denied
- `/code/secrets/tmp` can still be reopened as writable if explicitly
allowed
Before this, Linux could lose one of those carveouts depending on mount
order or legacy-policy fallback. This PR keeps the split-policy
semantics intact and rejects configurations that legacy Landlock cannot
represent safely.
## Summary
- rename the public feature flag for `spawn_agents_on_csv()` from
`spawn_csv` to `enable_fanout`
- regenerate the config schema so only `enable_fanout` is advertised
- keep the behavior the same: enabling `enable_fanout` still pulls in
`multi_agent`
## Notes
- this is a hard rename with no `spawn_csv` compatibility alias
- the internal enum remains `Feature::SpawnCsv` to keep the patch small
## Testing
- `cd codex-rs && just fmt`
- `cd codex-rs && cargo test -p codex-core` (running locally;
`suite::agent_jobs::*` and rename-specific coverage passed so far)
- **Summary**
- migrate the code mode handler, service, worker, process, runner, and
bridge assets into the `tools/code_mode` module tree
- split Execution, protocol, and handler logic into dedicated files and
relocate the tool definition into `code_mode/spec.rs`
- update core references and tests to stitch the new organization
together
- **Testing**
- Not run (not requested)
## What changed
- `codex-stdio-to-uds` now tolerates `NotConnected` when
`shutdown(Write)` happens after the peer has already closed.
- The socket test was rewritten to send stdin from a fixture file and to
read an exact request payload length instead of waiting on EOF timing.
## Why this fixes the flake
- This one exposed a real cross-platform runtime edge case: on macOS,
the peer can close first after a successful exchange, and
`shutdown(Write)` can report `NotConnected` even though the interaction
already succeeded.
- Treating that specific ordering as a harmless shutdown condition
removes the production-level false failure.
- The old test compounded the problem by depending on EOF timing, which
varies by platform and scheduler. Exact-length IO makes the test
deterministic and focused on the actual data exchange.
## Scope
- Production logic change with matching test rewrite.
## Summary
- restore `use_linux_sandbox_bwrap` as a removed feature key so older
`--enable` callers parse again
- keep it as a no-op by leaving runtime behavior unchanged
- add regression coverage for the legacy `--enable` path
## Testing
- Not run (updated and pushed quickly)
## TL;DR
Bring the Python app-server SDK from `main-with-prs-13953-and-14232`
onto current `main` as a standalone SDK-only PR.
- adds the new `sdk/python` and `sdk/python-runtime` package trees
- keeps the scope to the SDK payload only, without the unrelated
branch-history or workflow changes from the source branch
- regenerates `sdk/python/src/codex_app_server/generated/v2_all.py`
against current `main` schema so the extracted SDK matches today's
protocol definitions
## Validation
- `PYTHONPATH=sdk/python/src python3 -m pytest sdk/python/tests`

## Summary
- start a code mode worker once per turn and let it pump nested tool
calls through a dedicated queue
- simplify code mode request/response dispatch around request ids and
generic runner-unavailable errors
- clean up the code mode process API and runner protocol plumbing
## Testing
- not run yet
## Why
PR #13783 moved the `codex.rs` unit tests into `codex_tests.rs`. This
applies the same extraction pattern across the rest of `codex-rs/core`
so the production modules stay focused on runtime code instead of large
inline test blocks.
Keeping the tests in sibling files also makes follow-up edits easier to
review because product changes no longer have to share a file with
hundreds or thousands of lines of test scaffolding.
## What changed
- replaced each inline `mod tests { ... }` in `codex-rs/core/src/**`
with a path-based module declaration
- moved each extracted unit test module into a sibling `*_tests.rs`
file, using `mod_tests.rs` for `mod.rs` modules
- preserved the existing `cfg(...)` guards and module-local structure so
the refactor remains structural rather than behavioral
## Testing
- `cargo test -p codex-core --lib` (`1653 passed; 0 failed; 5 ignored`)
- `just fix -p codex-core`
- `cargo fmt --check`
- `cargo shear`
## Summary
- address the follow-up review nits from #13996 in a separate PR
- make the approvals test command a raw string and keep the
managed-network path using env proxy routing
- inline `--apply-seccomp-then-exec` in the Linux sandbox inner command
builder
- remove the bubblewrap-specific sandbox metric tag path and drop the
`use_legacy_landlock` shim from `sandbox_tag`/`TurnMetadataState::new`
- restore the `Feature` import that `origin/main` currently still needs
in `connectors.rs`
## Testing
- `cargo test -p codex-linux-sandbox`
- focused `codex-core` tests were rerun/started, but the final
verification pass was interrupted when I pushed at request
## Summary
- make bubblewrap the default Linux sandbox and keep
`use_legacy_landlock` as the only override
- remove `use_linux_sandbox_bwrap` from feature, config, schema, and
docs surfaces
- update Linux sandbox selection, CLI/config plumbing, and related
tests/docs to match the new default
- fold in the follow-up CI fixes for request-permissions responses and
Linux read-only sandbox error text
- Curated repo sync now uses GitHub HTTP, not local git.
- Curated plugin cache/versioning now uses commit SHA instead of local.
- Startup sync now always repairs or refreshes curated plugin cache from
tmp (auto update to the lastest)
## Summary
- persist the code mode runner process in the session-scoped code mode
store
- switch the runner protocol from `init` to `start` with explicit
session ids
- handle runner-side session processing without the init waiter queue
## Validation
- just fmt
- cargo check -p codex-core
- node --check codex-rs/core/src/tools/code_mode_runner.cjs
- Clarify that spawn_agent requires explicit user permission for
delegation or parallel agent work.
- Add a regression test covering the new description text.
make `AVAILABLE` the default plugin installPolicy when unset in
`marketplace.json`. similarly, make `ON_INSTALL` the default authPolicy.
this means, when unset, plugins are available to be installed (but not
auto-installed), and the contained connectors will be authed at
install-time.
updated tests.
## Summary
This PR keeps app-server RPC request trace context alive for the full
lifetime of the work that request kicks off (e.g. for `thread/start`,
this is `app-server rpc handler -> tokio background task -> core op
submissions`). Previously we lose trace lineage once the request handler
returns or hands work off to background tasks.
This approach is especially relevant for `thread/start` and other RPC
handlers that run in a non-blocking way. In the near future we'll most
likely want to make all app-server handlers run in a non-blocking way by
default, and only queue operations that must operate in order (e.g.
thread RPCs per thread?), so we want to make sure tracing in app-server
just generally works.

## What changed
- Keep request-scoped trace context around until we send the final
response or error, or the connection closes.
- Thread that trace context through detached `thread/start` work so
background startup stays attached to the originating request.
- Pass request trace context through to downstream core operations,
including:
- thread creation
- resume/fork flows
- turn submission
- review
- interrupt
- realtime conversation operations
- Add tracing tests that verify:
- remote W3C trace context is preserved for `thread/start`
- remote W3C trace context is preserved for `turn/start`
- downstream core spans stay under the originating request span
- request-scoped tracing state is cleaned up correctly
- Clean up shutdown behavior so detached background tasks and spawned
threads are drained before process exit.
- add model and reasoning effort to app-server collab spawn items and
notifications
- regenerate app-server protocol schemas for the new fields

## Stack
fix: fail closed for unsupported split windows sandboxing #14172
fix: preserve split filesystem semantics in linux sandbox #14173
-> fix: align core approvals with split sandbox policies #14171
refactor: centralize filesystem permissions precedence #14174
## Why This PR Exists
This PR is intentionally narrower than the title may suggest.
Most of the original split-permissions migration already landed in the
earlier `#13434 -> #13453` stack. In particular:
- `#13439` already did the broad runtime plumbing for split filesystem
and network policies.
- `#13445` already moved `apply_patch` safety onto filesystem-policy
semantics.
- `#13448` already switched macOS Seatbelt generation to split policies.
- `#13449` and `#13453` already handled Linux helper and bubblewrap
enforcement.
- `#13440` already introduced the first protocol-side helpers for
deriving effective filesystem access.
The reason this PR still exists is that after the follow-on
`[permissions]` work and the new shared precedence helper in `#14174`, a
few core approval paths were still deciding behavior from the legacy
`SandboxPolicy` projection instead of the split filesystem policy that
actually carries the carveouts.
That means this PR is mostly a cleanup and alignment pass over the
remaining core consumers, not a fresh sandbox backend migration.
## What Is Actually New Here
- make unmatched-command fallback decisions consult
`FileSystemSandboxPolicy` instead of only legacy `DangerFullAccess` /
`ReadOnly` / `WorkspaceWrite` categories
- thread `file_system_sandbox_policy` into the shell, unified-exec, and
intercepted-exec approval paths so they all use the same split-policy
semantics
- keep `apply_patch` safety on the same effective-access rules as the
shared protocol helper, rather than letting it drift through
compatibility projections
- add loader-level regression coverage proving legacy `sandbox_mode`
config still builds split policies and round-trips back without semantic
drift
## What This PR Does Not Do
This PR does not introduce new platform backend enforcement on its own.
- Linux backend parity remains in `#14173`.
- Windows fail-closed handling remains in `#14172`.
- The shared precedence/model changes live in `#14174`.
## Files To Focus On
- `core/src/exec_policy.rs`: unmatched-command fallback and approval
rendering now read the split filesystem policy directly
- `core/src/tools/sandboxing.rs`: default exec-approval requirement keys
off `FileSystemSandboxPolicy.kind`
- `core/src/tools/handlers/shell.rs`: shell approval requests now carry
the split filesystem policy
- `core/src/unified_exec/process_manager.rs`: unified-exec approval
requests now carry the split filesystem policy
- `core/src/tools/runtimes/shell/unix_escalation.rs`: intercepted exec
fallback now uses the same split-policy approval semantics
- `core/src/safety.rs`: `apply_patch` safety keeps using effective
filesystem access rather than legacy sandbox categories
- `core/src/config/config_tests.rs`: new regression coverage for legacy
`sandbox_mode` no-drift behavior through the split-policy loader
## Notes
- `core/src/codex.rs` and `core/src/codex_tests.rs` are just small
fallout updates for `RequestPermissionsResponse.scope`; they are not the
point of the PR.
- If you reviewed the earlier `#13439` / `#13445` stack, the main review
question here is simply: “are there any remaining approval or
patch-safety paths that still reconstruct semantics from legacy
`SandboxPolicy` instead of consuming the split filesystem policy
directly?”

## Description
This PR trims `app-server-protocol`'s v1 surface down to the small set
of legacy types we still actually use.
Unfortunately, we can't delete all of them yet because:
- a few one-off v1 RPCs are still used by the Codex app
- a few of these app-server-protocol v1 types are actually imported by
core crates
This change deletes that unused RPC surface, keeps the remaining
compatibility types in place, and makes the crate root re-export only
the v1 structs that downstream crates still depend on.
## Why
The main goal here is to make the legacy protocol surface match reality.
Leaving a large pile of dead v1 structs in place makes it harder to tell
which compatibility paths are still intentional, and it keeps old
schema/types around even though nothing should be building against them
anymore.
This also gives us a cleaner boundary for future cleanup. Instead of
re-exporting all of `protocol::v1::*`, the crate now explicitly exposes
only the v1 types that are still live, which makes it much easier to see
what remains and delete more safely later.
## What changed
- Deleted the unused v1 RPC/request/response structs from
`app-server-protocol/src/protocol/v1.rs`.
- Kept the small set of v1 compatibility types that are still live,
including:
- `initialize`
- `getConversationSummary`
- `getAuthStatus`
- `gitDiffToRemote`
- legacy approval payloads
- config-related structs still used by downstream crates
- Replaced the blanket `pub use protocol::v1::*` export in
`app-server-protocol/src/lib.rs` with an explicit list of the remaining
supported v1 types.
- Regenerated the schema/type artifacts, which also updated the
`InitializeCapabilities` opt-out example to use `thread/started` instead
of the old `codex/event/session_configured` example.
## Validation
- `just write-app-server-schema`
- `cargo test -p codex-app-server-protocol`
## Follow-up
The next cleanup is to keep shrinking the remaining v1 compatibility
surface as callers migrate off it. Once the remaining consumers stop
importing these legacy types, we should be able to remove more of the v1
module and eventually stop exporting it from the crate root entirely.
## Why
to support a new bring your own search tool in Responses
API(https://developers.openai.com/api/docs/guides/tools-tool-search#client-executed-tool-search)
we migrating our bm25 search tool to use official way to execute search
on client and communicate additional tools to the model.
## What
- replace the legacy `search_tool_bm25` flow with client-executed
`tool_search`
- add protocol, SSE, history, and normalization support for
`tool_search_call` and `tool_search_output`
- return namespaced Codex Apps search results and wire namespaced
follow-up tool calls back into MCP dispatch
## Description
This PR stops emitting legacy `codex/event/*` notifications from the
public app-server transports.
It's been a long time coming! app-server was still producing a raw
notification stream from core, alongside the typed app-server
notifications and server requests, for compatibility reasons. Now,
external clients should no longer be depending on those legacy
notifications, so this change removes them from the stdio and websocket
contract and updates the surrounding docs, examples, and tests to match.
### Caveat
I left the "in-process" version of app-server alone for now, since
`codex exec` was recently based on top of app-server via this in-process
form here: https://github.com/openai/codex/pull/14005
Seems like `codex exec` still consumes some legacy notifications
internally, so this branch only removes `codex/event/*` from app-server
over stdio and websockets.
## Follow-up
Once `codex exec` is fully migrated off `codex/event/*` notifications,
we'll be able to stop emitting them entirely entirely instead of just
filtering it at the external transport boundary.
Prevent binaries >500KB from being committed. And maintain an allowlist
if we need to bypass on a case-by-case basis.
I checked the currently tracked binary-like assets in the repo. There
are only 5 obvious committed binaries by extension/MIME type:
- `.github/codex-cli-splash.png`: `838,131` bytes, about `818 KiB`
- `codex-rs/vendor/bubblewrap/bubblewrap.jpg`: `40,239` bytes, about `39
KiB`
-
`codex-rs/skills/src/assets/samples/skill-creator/assets/skill-creator.png`:

- `codex-rs/skills/src/assets/samples/openai-docs/assets/openai.png`:
`1,429` bytes
-
`codex-rs/skills/src/assets/samples/skill-installer/assets/skill-installer.png`:
`1,086` bytes
So `500 KB` looks like a good default for this repo. It would only trip
on one existing intentional asset, which keeps the allowlist small and
the policy easy to understand.

## Summary
This PR narrows original image detail handling to a single opt-in
feature:
- `image_detail_original` lets the model request `detail: "original"` on
supported models
- Omitting `detail` preserves the default resized behavior
The model only sees `detail: "original"` guidance when the active model
supports it:
- JS REPL instructions include the guidance and examples only on
supported models
- `view_image` only exposes a `detail` parameter when the feature and
model can use it
The image detail API is intentionally narrow and consistent across both
paths:
- `view_image.detail` supports only `"original"`; otherwise omit the
field
- `codex.emitImage(..., detail)` supports only `"original"`; otherwise
omit the field
- Unsupported explicit values fail clearly at the API boundary instead
of being silently reinterpreted
- Unsupported explicit `detail: "original"` requests fall back to normal
behavior when the feature is disabled or the model does not support
original detail
## Summary
- only trigger multi-agent fast-switch shortcuts when the composer is
empty
- keep the Option+b/f fallback for terminals that encode Option+arrow
that way
- document why the empty-composer gate preserves expected word-wise
editing behavior
## Testing

## Summary
This PR adds two read-only path helpers to `js_repl`:
- `codex.cwd`
- `codex.homeDir`
They are exposed alongside the existing `codex.tmpDir` helper so the
REPL can reference basic host path context without reopening direct
`process` access.
## Implementation
- expose `codex.cwd` and `codex.homeDir` from the js_repl kernel
- make `codex.homeDir` come from the kernel process environment
- pass session dependency env through js_repl kernel startup so
`codex.homeDir` matches the env a shell-launched process would see
- keep existing shell `HOME` population behavior unchanged
- update js_repl prompt/docs and add runtime/integration coverage for
the new helpers
## Summary
- switch the local HTTP proxy listener from Rama's auto server to
explicit HTTP/1 so CONNECT clients skip the version-sniffing pre-read
path
- move rustls crypto-provider bootstrap into the HTTP proxy runner so
direct callers do not need hidden global init
- add a regression test that exercises a plain HTTP/1 CONNECT request
against a live loopback listener
## Summary
- defer fresh-session `build_initial_context()` until the first real
turn instead of seeding model-visible context during startup
- rely on the existing `reference_context_item == None` turn-start path
to inject full initial context on that first real turn (and again after
baseline resets such as compaction)
- add a regression test for `InitialHistory::New` and update affected
deterministic tests / snapshots around developer-message layout,
collaboration instructions, personality updates, and compact request
shapes
## Notes
- this PR does not add any special empty-thread `/compact` behavior
- most of the snapshot churn is the direct result of moving the initial
model-visible context from startup to the first real turn, so first-turn
request layouts no longer contain a pre-user startup copy of permissions
/ environment / other developer-visible context
- remote manual `/compact` with no prior user still skips the remote
compact request; local first-turn `/compact` still issues a compact
request, but that request now reflects the lack of startup-seeded
context

## Summary
This PR fixes OTLP HTTP trace export in runtimes where the previous
exporter setup was unreliable, especially around app-server usage. It
also removes the old `codex_otel::otel_provider` compatibility shim and
switches remaining call sites over to the crate-root
`codex_otel::OtelProvider` export.
## What changed
- Use a runtime-safe OTLP HTTP trace exporter path for Tokio runtimes.
- Add an async HTTP client path for trace export when we are already
inside a multi-thread Tokio runtime.
- Make provider shutdown flush traces before tearing down the tracer
provider.
- Add loopback coverage that verifies traces are actually sent to
`/v1/traces`:
- outside Tokio
- inside a multi-thread Tokio runtime
- inside a current-thread Tokio runtime
- Remove the `codex_otel::otel_provider` shim and update remaining
imports.
## Why
I hit cases where spans were being created correctly but never made it
to the collector. The issue turned out to be in exporter/runtime
behavior rather than the span plumbing itself. This PR narrows that gap
and gives us regression coverage for the actual export path.
Summary
- add a custom deserializer so `[tools].web_search` can be a bool
(treated as disabled) or a config object
- extend core and app-server tests to cover bool handling in TOML config
Testing
- Not run (not requested)
## What changed
- Drop failed websocket connections immediately after a terminal stream
error instead of awaiting a graceful close handshake before forwarding
the error to the caller.
- Keep the success path and the closed-connection guard behavior
unchanged.
## Why this fixes the flake
- The failing integration test waits for the second websocket stream to
surface the model error before issuing a follow-up request.
- On slower runners, the old error path awaited
`ws_stream.close().await` before sending the error downstream. If that
close handshake stalled, the test kept waiting for an error that had
already happened server-side and nextest timed it out.
- Dropping the failed websocket immediately makes the terminal error
observable right away and marks the session closed so the next request
reconnects cleanly instead of depending on a best-effort close
handshake.
## Code or test?
- This is a production logic fix in `codex-api`. The existing websocket
integration test already exercises the regression path.
- include the requested sub-agent model and reasoning effort in the
spawn begin event\n- render that metadata next to the spawned agent name
and role in the TUI transcript

Summary
- update the code-mode handler, runner, instructions, and error text to
refer to the `exec` tool name everywhere that used to say `code_mode`
- ensure generated documentation strings and tool specs describe `exec`
and rely on the shared `PUBLIC_TOOL_NAME`
- refresh the suite tests so they invoke `exec` instead of the old name
Testing
- Not run (not requested)
## Summary
- update the guardian prompting
- clarify the guardian rejection message so an action may still proceed
if the user explicitly approves it after being informed of the risk
## Testing
- cargo run on selected examples
## What changed
- keep the explicit stdin-close behavior after writing so the child
still receives EOF deterministically
- on Windows, stop using `python -c` for the round-trip assertion and
instead run a native `cmd.exe` pipeline that reads one line from stdin
with `set /p` and echoes it back
- send `
` on Windows so the stdin payload matches the platform-native line
ending the shell reader expects
## Why this fixes flakiness
The failing branch-local flake was not in `spawn_pipe_process` itself.
The child exited cleanly, but the Windows ARM runner sometimes produced
an empty stdout string when the test used Python as the stdin consumer.
That makes the test sensitive to Python startup and stdin-close timing
rather than the pipe primitive we actually want to validate. Switching
the Windows path to a native `cmd.exe` reader keeps the assertion
focused on our pipe behavior: bytes written to stdin should come back on
stdout before EOF closes the process. The explicit `
` write removes line-ending ambiguity on Windows.
## Scope
- test-only
- no production logic change
## Summary
- add `skill_approval` to `RejectConfig` and the app-server v2
`AskForApproval::Reject` payload so skill-script prompts can be
configured independently from sandbox and rule-based prompts
- update Unix shell escalation to reject prompts based on the actual
decision source, keeping prefix rules tied to `rules`, unmatched command
fallbacks tied to `sandbox_approval`, and skill scripts tied to
`skill_approval`
- regenerate the affected protocol/config schemas and expand
unit/integration coverage for the new flag and skill approval behavior
Pass more params to /compact. This should give us parity with the
/responses endpoint to improve caching.
I'm torn about the MCP await. Blocking will give us parity but it seems
like we explicitly don't block on MCPs. Happy either way
### Summary
This PR adds first-class ephemeral support to thread/fork, bringing it
in line with thread/start. The goal is to support one-off completions on
full forked threads without persisting them as normal user-visible
threads.
### Testing
Summary
- document how code-mode can import `output_text`/`output_image` and
ensure `add_content` stays compatible
- add a synthetic `@openai/code_mode` module that appends content items
and validates inputs
- cover the new behavior with integration tests for structured text and
image outputs
Testing
- Not run (not requested)
- clarify the `close_agent` tool description so it nudges models to
close agents they no longer need
- keep the change scoped to the tool spec text only

- raise the sdk workflow job timeout from 10 to 15 minutes to reduce
false cancellations near the current limit

Summary
- document that `@openai/code_mode` exposes
`set_max_output_tokens_per_exec_call` and that `code_mode` truncates the
final Rust-side output when the budget is exceeded
- enforce the configured budget in the Rust tool runner, reusing
truncation helpers so text-only outputs follow the unified-exec wrapper
and mixed outputs still fit within the limit
- ensure the new behavior is covered by a code-mode integration test and
string spec update
Testing
- Not run (not requested)
Summary
- drop `McpToolOutput` in favor of `CallToolResult`, moving its helpers
to keep MCP tooling focused on the final result shape
- wire the new schema definitions through code mode, context, handlers,
and spec modules so MCP tools serialize the exact output shape expected
by the model
- extend code mode tests to cover multiple MCP call scenarios and ensure
the serialized data matches the new schema
- refresh JS runner helpers and protocol models alongside the schema
changes
Testing
- Not run (not requested)
- add `model` and `reasoning_effort` to the `spawn_agent` schema so the
values pass through
- validate requested models against `model.model` and only check that
the selected model supports the requested reasoning effort

## Summary
- add ARC monitor support for MCP tool calls by serializing MCP approval
requests into the ARC action shape and sending the relevant
conversation/policy context to the `/api/codex/safety/arc` endpoint
- route ARC outcomes back into MCP approval flow so `ask-user` falls
back to a user prompt and `steer-model` blocks the tool call, with
guardian/ARC tests covering the new request shape
- update the TUI approval copy from “Approve Once” to “Allow” / “Allow
for this session” and refresh the related
snapshots

## Summary
- add the OpenAI Docs skill under
codex-rs/skills/src/assets/samples/openai-docs
- include the skill metadata, assets, and GPT-5.4 upgrade reference
files
- exclude the test harness and test fixtures
## Testing
- not run (skill-only asset copy)
This updates the `skill-creator` sample skill to explicitly cover
forward-testing as part of the skill authoring workflow. The guidance
now treats subagent-based validation as a first-class step for complex
or fragile skills, with an emphasis on preserving evaluation integrity
and avoiding leaked context.
The sample initialization script is also updated so newly created skills
point authors toward forward-testing after validation. Together, these
changes make the sample more opinionated about how skills should be
iterated on once the initial implementation is complete.
- Add new guidance to `SKILL.md` on protecting validation integrity,
when to use subagents for forward-testing, and how to structure
realistic test prompts without leaking expected answers.
- Expand the skill creation workflow so iteration explicitly includes
forward-testing for complex skills, including approval guidance for
expensive or risky validation runs.
Fixes a Codex app bug where quitting the app mid-run could leave the
reopened thread stuck in progress and non-interactable. On cold thread
resume, app-server could return an idle thread with a replayed turn
still marked in progress. This marks incomplete replayed turns as
interrupted unless the thread is actually active.
## Summary
- run the split stdout/stderr PTY test through the normal shell helper
on every platform
- use a Windows-native command string instead of depending on Python to
emit split streams
- assert CRLF line endings on Windows explicitly
## Why this fixes the flake
The earlier PTY split-output test used a Python one-liner on Windows
while the rest of the file exercised shell-command behavior. That made
the test depend on runner-local Python availability and masked the real
Windows shell output shape. Using a native cmd-compatible command and
asserting the actual CRLF output makes the split stdout/stderr coverage
deterministic on Windows runners.
Summary
- document output types for the various tool handlers and registry so
the API exposes richer descriptions
- update unified execution helpers and client tests to align with the
new output metadata
- clean up unused helpers across tool dispatch paths
Testing
- Not run (not requested)
There are some bug investigations that currently require us to ask users
for their user ID even though they've already uploaded logs and session
details via `/feedback`. This frustrates users and increases the time
for diagnosis.
This PR includes the ChatGPT user ID in the metadata uploaded for
`/feedback` (both the TUI and app-server).
Replace the Unix shell lookup path in `codex-rs/core/src/shell.rs` to
use
`libc::getpwuid_r()` instead of `libc::getpwuid()` when resolving the
current
user's shell.
Why:
- `getpwuid()` can return pointers into libc-managed shared storage
- on the musl static Linux build, concurrent callers can race on that
storage
- this matches the crash pattern reported in tmux/Linux sessions with
parallel
shell activity

Addresses #13586
This doesn't affect our CI scripts. It was user-reported.
Summary
- add `wiremock::ResponseTemplate` and `body_string_contains` imports
behind `#[cfg(not(debug_assertions))]` in
`codex-rs/core/tests/suite/view_image.rs` so release builds only pull
the helpers they actually use
