## 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.
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
- 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
- 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)
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
- 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)
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
## What changed
- The retry test now uses the same streaming SSE test server used by
production-style tests instead of a wiremock sequence.
- The fixture is resolved via `find_resource!`, and the test asserts
that exactly two outbound requests were sent.
## Why this fixes the flake
- The old wiremock sequence approximated early-close behavior, but it
did not reproduce the same streaming semantics the real client sees.
- That meant the retry path depended on mock implementation details
instead of on the actual transport behavior we care about.
- Switching to the streaming SSE helper makes the test exercise the real
early-close/retry contract, and counting requests directly verifies that
we retried exactly once rather than merely hoping the sequence aligned.
## Scope
- Test-only change.
- collect input/output transcript deltas into active handoff transcript
state
- attach and clear that transcript on each handoff, and regenerate
schema/tests
**Summary**
- allow `code_mode` to pass enabled tools metadata to the runner and
expose them via `tools.js`
- import tools inside JavaScript rather than relying only on globals or
proxies for nested tool calls
- update specs, docs, and tests to exercise the new bridge and explain
the tooling changes
**Testing**
- Not run (not requested)
## Summary
We need to support allowing request_permissions calls when using
`Reject` policy

Note that this is a backwards-incompatible change for Reject policy. I'm
not sure if we need to add a default based on our current use/setup
## Testing

## Summary
request_permissions flows should support persisting results for the
session.
Open Question: Still deciding if we need within-turn approvals - this
adds complexity but I could see it being useful
## Testing
- [x] Updated unit tests
---------
Co-authored-by: Codex <noreply@openai.com>
## What changed
- The RMCP streamable HTTP tests now wait for metadata and tool
readiness before issuing tool calls.
- OAuth state is isolated per test home.
- The helper server startup path now uses bounded bind retries so
transient `AddrInUse` collisions do not fail the test immediately.
## Why this fixes the flake
- The old tests could begin issuing tool requests before the helper
server had finished advertising its metadata and tools, so the first
request sometimes raced the server startup sequence.
- On top of that, shared OAuth state and occasional bind collisions on
CI runners introduced cross-test environmental noise unrelated to the
functionality under test.
- Readiness polling makes the client wait for an observable “server is
ready” signal, while isolated state and bounded bind retries remove
external contention that was causing intermittent failures.
## Scope
- Test-only change.
## Summary
Alternative to #14061 - we need to use a child process on windows to
correctly validate Powershell behavior.
## Testing
- [x] These are tests
## What changed
- add a bounded `resume_until_initial_messages` helper in
`core/tests/suite/resume.rs`
- retry the resume call until `initial_messages` contains the fully
persisted final turn shape before asserting
## Why this fixes flakiness
The old test resumed once immediately after `TurnComplete` and sometimes
read rollout state before the final turn had been persisted. That made
the assertion race persistence timing instead of checking the resumed
message shape. The new helper polls for up to two seconds in 10ms steps
and only asserts once the expected message sequence is actually present,
so the test waits for the real readiness condition instead of depending
on a lucky timing window.
## Scope
- test-only
- no production logic change
## What changed
- The realtime startup-context tests no longer assume the interesting
websocket payload is always `connection 1 / request 0`.
- Instead, they now wait for the first outbound websocket request that
actually carries `session.instructions`, regardless of which websocket
connection won the accept-order race on the runner.
- The env-key fallback test stays serialized because it mutates process
environment.
## Why this fixes the flake
- The old test synchronized on the mirrored `session.updated` client
event and then inspected a fixed websocket slot.
- On CI, the response websocket and the realtime websocket can race each
other during startup. When the response websocket wins that race, the
fixed slot can contain `response.create` instead of the
startup-context-bearing `session.update` request the test actually cares
about.
- That made the test fail nondeterministically by inspecting the wrong
request, or by timing out waiting on a secondary event even though the
real outbound request path was correct.
- Waiting directly on the first request whose payload includes
`session.instructions` removes both ordering assumptions and makes the
assertion line up with the actual contract under test.
- Separately, serializing the environment-mutating fallback case
prevents unrelated tests from seeing partially updated auth state.
## Scope
- Test-only change.
## Summary
- remove the remaining model-visible guardian-specific `on-request`
prompt additions so enabling the feature does not change the main
approval-policy instructions
- neutralize user-facing guardian wording to talk about automatic
approval review / approval requests rather than a second reviewer or
only sandbox escalations
- tighten guardian retry-context handling so agent-authored
`justification` stays in the structured action JSON and is not also
injected as raw retry context
- simplify guardian review plumbing in core by deleting dead
prompt-append paths and trimming some request/transcript setup code
## Notable Changes
- delete the dead `permissions/approval_policy/guardian.md` append path
and stop threading `guardian_approval_enabled` through model-facing
developer-instruction builders
- rename the experimental feature copy to `Automatic approval review`
and update the `/experimental` snapshot text accordingly
- make approval-review status strings generic across shell, patch,
network, and MCP review types
- forward real sandbox/network retry reasons for shell and unified-exec
guardian review, but do not pass agent-authored justification as raw
retry context
- simplify `guardian.rs` by removing the one-field request wrapper,
deduping reasoning-effort selection, and cleaning up transcript entry
collection
## Testing
- `just fmt`
- full validation left to CI

Adds a built-in `request_permissions` tool and wires it through the
Codex core, protocol, and app-server layers so a running turn can ask
the client for additional permissions instead of relying on a static
session policy.
The new flow emits a `RequestPermissions` event from core, tracks the
pending request by call ID, forwards it through app-server v2 as an
`item/permissions/requestApproval` request, and resumes the tool call
once the client returns an approved subset of the requested permission
profile.
## Summary
This test was missing the turn completion event in the responses stream,
so it was hanging. This PR fixes the issue
## Testing
- [x] This does update the test
## What changed
- The duration-recording fixture sleep was reduced from a large
artificial delay to `0.2s`, and the assertion floor was lowered to
`0.1s`.
- The shell tool fixtures now force `login = false` so they do not
invoke login-shell startup paths.
## Why this fixes the flake
- The old tests were paying for two kinds of noise that had nothing to
do with the feature being validated: oversized sleep time and variable
shell initialization cost.
- Login shells can pick up runner-specific startup files and incur
inconsistent startup latency.
- The test only needs to prove that we record a nontrivial duration and
preserve shell output. A shorter fixture delay plus a non-login shell
keeps that coverage while removing runner-dependent wall-clock variance.
## Scope
- Test-only change.
## Why
After `#13440` and `#13445`, macOS Seatbelt policy generation was still
deriving filesystem and network behavior from the legacy `SandboxPolicy`
projection.
That projection loses explicit unreadable carveouts and conflates split
network decisions, so the generated Seatbelt policy could still be wider
than the split policy that Codex had already computed.
## What changed
- added Seatbelt entrypoints that accept `FileSystemSandboxPolicy` and
`NetworkSandboxPolicy` directly
- built read and write policy stanzas from access roots plus excluded
subpaths so explicit unreadable carveouts survive into the generated
Seatbelt policy
- switched network policy generation to consult `NetworkSandboxPolicy`
directly
- failed closed when managed-network or proxy-constrained sessions do
not yield usable loopback proxy endpoints
- updated the macOS callers and test helpers that now need to carry the
split policies explicitly
## Verification
- added regression coverage in `core/src/seatbelt.rs` for unreadable
carveouts under both full-disk and scoped-readable policies
- verified the current PR state with `just clippy`

## Summary
- add the guardian reviewer flow for `on-request` approvals in command,
patch, sandbox-retry, and managed-network approval paths
- keep guardian behind `features.guardian_approval` instead of exposing
a public `approval_policy = guardian` mode
- route ordinary `OnRequest` approvals to the guardian subagent when the
feature is enabled, without changing the public approval-mode surface
## Public model
- public approval modes stay unchanged
- guardian is enabled via `features.guardian_approval`
- when that feature is on, `approval_policy = on-request` keeps the same
approval boundaries but sends those approval requests to the guardian
reviewer instead of the user
- `/experimental` only persists the feature flag; it does not rewrite
`approval_policy`
- CLI and app-server no longer expose a separate `guardian` approval
mode in this PR
## Guardian reviewer
- the reviewer runs as a normal subagent and reuses the existing
subagent/thread machinery
- it is locked to a read-only sandbox and `approval_policy = never`
- it does not inherit user/project exec-policy rules
- it prefers `gpt-5.4` when the current provider exposes it, otherwise
falls back to the parent turn's active model
- it fail-closes on timeout, startup failure, malformed output, or any
other review error
- it currently auto-approves only when `risk_score < 80`
## Review context and policy
- guardian mirrors `OnRequest` approval semantics rather than
introducing a separate approval policy
- explicit `require_escalated` requests follow the same approval surface
as `OnRequest`; the difference is only who reviews them
- managed-network allowlist misses that enter the approval flow are also
reviewed by guardian
- the review prompt includes bounded recent transcript history plus
recent tool call/result evidence
- transcript entries and planned-action strings are truncated with
explicit `<guardian_truncated ... />` markers so large payloads stay
bounded
- apply-patch reviews include the full patch content (without
duplicating the structured `changes` payload)
- the guardian request layout is snapshot-tested using the same
model-visible Responses request formatter used elsewhere in core
## Guardian network behavior
- the guardian subagent inherits the parent session's managed-network
allowlist when one exists, so it can use the same approved network
surface while reviewing
- exact session-scoped network approvals are copied into the guardian
session with protocol/port scope preserved
- those copied approvals are now seeded before the guardian's first turn
is submitted, so inherited approvals are available during any immediate
review-time checks
## Out of scope / follow-ups
- the sandbox-permission validation split was pulled into a separate PR
and is not part of this diff
- a future follow-up can enable `serde_json` preserve-order in
`codex-core` and then simplify the guardian action rendering further
---------

## Summary
- distinguish reject-policy handling for prefix-rule approvals versus
sandbox approvals in Unix shell escalation
- keep prompting for skill-script execution when `rules=true` but
`sandbox_approval=false`, instead of denying the command up front
- add regression coverage for both skill-script reject-policy paths in
`codex-rs/core/tests/suite/skill_approval.rs`
## Why
`#13434` introduces split `FileSystemSandboxPolicy` and
`NetworkSandboxPolicy`, but the runtime still made most execution-time
sandbox decisions from the legacy `SandboxPolicy` projection.
That projection loses information about combinations like unrestricted
filesystem access with restricted network access. In practice, that
means the runtime can choose the wrong platform sandbox behavior or set
the wrong network-restriction environment for a command even when config
has already separated those concerns.
This PR carries the split policies through the runtime so sandbox
selection, process spawning, and exec handling can consult the policy
that actually matters.
## What changed
- threaded `FileSystemSandboxPolicy` and `NetworkSandboxPolicy` through
`TurnContext`, `ExecRequest`, sandbox attempts, shell escalation state,
unified exec, and app-server exec overrides
- updated sandbox selection in `core/src/sandboxing/mod.rs` and
`core/src/exec.rs` to key off `FileSystemSandboxPolicy.kind` plus
`NetworkSandboxPolicy`, rather than inferring behavior only from the
legacy `SandboxPolicy`
- updated process spawning in `core/src/spawn.rs` and the platform
wrappers to use `NetworkSandboxPolicy` when deciding whether to set
`CODEX_SANDBOX_NETWORK_DISABLED`
- kept additional-permissions handling and legacy `ExternalSandbox`
compatibility projections aligned with the split policies, including
explicit user-shell execution and Windows restricted-token routing
- updated callers across `core`, `app-server`, and `linux-sandbox` to
pass the split policies explicitly
## Verification
- added regression coverage in `core/tests/suite/user_shell_cmd.rs` to
verify `RunUserShellCommand` does not inherit
`CODEX_SANDBOX_NETWORK_DISABLED` from the active turn
- added coverage in `core/src/exec.rs` for Windows restricted-token
sandbox selection when the legacy projection is `ExternalSandbox`
- updated Linux sandbox coverage in
`linux-sandbox/tests/suite/landlock.rs` to exercise the split-policy
exec path
- verified the current PR state with `just clippy`

Previously, we could only configure whether web search was on/off.
This PR enables sending along a web search config, which includes all
the stuff responsesapi supports: filters, location, etc.
## Summary
- Treat skill scripts with no permission profile, or an explicitly empty
one, as permissionless and run them with the turn's existing sandbox
instead of forcing an exec approval prompt.
- Keep the approval flow unchanged for skills that do declare additional
permissions.
- Update the skill approval tests to assert that permissionless skill
scripts do not prompt on either the initial run or a rerun.
## Why
Permissionless skills should inherit the current turn sandbox directly.
Prompting for exec approval in that case adds friction without granting
any additional capability.
## Summary
This is a purely mechanical refactor of `OtelManager` ->
`SessionTelemetry` to better convey what the struct is doing. No
behavior change.
## Why
`OtelManager` ended up sounding much broader than what this type
actually does. It doesn't manage OTEL globally; it's the session-scoped
telemetry surface for emitting log/trace events and recording metrics
with consistent session metadata (`app_version`, `model`, `slug`,
`originator`, etc.).
`SessionTelemetry` is a more accurate name, and updating the call sites
makes that boundary a lot easier to follow.
## Validation
- `just fmt`
- `cargo test -p codex-otel`
- `cargo test -p codex-core`
- add experimental_realtime_ws_startup_context to override or disable
realtime websocket startup context
- preserve generated startup context when unset and cover the new
override paths in tests
## Why
`SandboxPolicy` currently mixes together three separate concerns:
- parsing layered config from `config.toml`
- representing filesystem sandbox state
- carrying basic network policy alongside filesystem choices
That makes the existing config awkward to extend and blocks the new TOML
proposal where `[permissions]` becomes a table of named permission
profiles selected by `default_permissions`. (The idea is that if
`default_permissions` is not specified, we assume the user is opting
into the "traditional" way to configure the sandbox.)
This PR adds the config-side plumbing for those profiles while still
projecting back to the legacy `SandboxPolicy` shape that the current
macOS and Linux sandbox backends consume.
It also tightens the filesystem profile model so scoped entries only
exist for `:project_roots`, and so nested keys must stay within a
project root instead of using `.` or `..` traversal.
This drops support for the short-lived `[permissions.network]` in
`config.toml` because now that would be interpreted as a profile named
`network` within `[permissions]`.
## What Changed
- added `PermissionsToml`, `PermissionProfileToml`,
`FilesystemPermissionsToml`, and `FilesystemPermissionToml` so config
can parse named profiles under `[permissions.<profile>.filesystem]`
- added top-level `default_permissions` selection, validation for
missing or unknown profiles, and compilation from a named profile into
split `FileSystemSandboxPolicy` and `NetworkSandboxPolicy` values
- taught config loading to choose between the legacy `sandbox_mode` path
and the profile-based path without breaking legacy users
- introduced `codex-protocol::permissions` for the split filesystem and
network sandbox types, and stored those alongside the legacy projected
`sandbox_policy` in runtime `Permissions`
- modeled `FileSystemSpecialPath` so only `ProjectRoots` can carry a
nested `subpath`, matching the intended config syntax instead of
allowing invalid states for other special paths
- restricted scoped filesystem maps to `:project_roots`, with validation
that nested entries are non-empty descendant paths and cannot use `.` or
`..` to escape the project root
- kept existing runtime consumers working by projecting
`FileSystemSandboxPolicy` back into `SandboxPolicy`, with an explicit
error for profiles that request writes outside the workspace root
- loaded proxy settings from top-level `[network]`
- regenerated `core/config.schema.json`
## Verification
- added config coverage for profile deserialization,
`default_permissions` selection, top-level `[network]` loading, network
enablement, rejection of writes outside the workspace root, rejection of
nested entries for non-`:project_roots` special paths, and rejection of
parent-directory traversal in `:project_roots` maps
- added protocol coverage for the legacy bridge rejecting non-workspace
writes
## Docs
- update the Codex config docs on developers.openai.com/codex to
document named `[permissions.<profile>]` entries, `default_permissions`,
scoped `:project_roots` syntax, the descendant-path restriction for
nested `:project_roots` entries, and top-level `[network]` proxy
configuration

#### What
Add structured `@plugin` parsing and TUI support for plugin mentions.
- Core: switch from plain-text `@display_name` parsing to structured
`plugin://...` mentions via `UserInput::Mention` and
`[$...](plugin://...)` links in text, same pattern as apps/skills.
- TUI: add plugin mention popup, autocomplete, and chips when typing
`$`. Load plugin capability summaries and feed them into the composer;
plugin mentions appear alongside skills and apps.
- Generalize mention parsing to a sigil parameter, still defaults to `$`

/>
Builds on #13510. Currently clients have to build their own `id` via
`plugin@marketplace` and filter plugins to show by `enabled`, but we
will add `id` and `available` as fields returned from `plugin/list`
soon.
####Tests
Added tests, verified locally.
