## 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?”

## 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
## 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
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
- 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
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
Co-authored-by: Codex <noreply@openai.com>
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

This changes the web_search tool spec in codex-core to use dedicated
Responses-API payload structs instead of shared config types and custom
serializers.
Previously, `ToolSpec::WebSearch` stored `WebSearchFilters` and
`WebSearchUserLocation` directly and relied on hand-written serializers
to shape the outgoing JSON. This worked, but it mixed config/schema
types with the OpenAI Responses payload contract and created an easy
place for drift if those shared types changed later.
### Why
This keeps the boundary clearer:
- app-server/config/schema types stay focused on config
- Responses tool payload types stay focused on the OpenAI wire format
It also makes the serialization behavior obvious from the structs
themselves, instead of hiding it in custom serializer functions.
## 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

## Summary
- align the guardian permission test with the actual sandbox policy it
widens and use a slightly larger Windows-only timeout budget
- expose the additional-permissions normalization helper to the guardian
test module
- replace the guardian popup snapshot assertion with targeted string
assertions
## Why this fixes the flake
This group was carrying two separate sources of drift. The guardian core
test widened derived sandbox policies without updating the source
sandbox policy, and it used a Windows command/timeout combination that
was too tight on slower runners. Separately, the TUI test was
snapshotting the full popup even though unrelated feature text changes
were the only thing moving. The new assertions keep coverage on the
guardian entry itself while removing unrelated snapshot churn.
## 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.
## 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`
## 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.
## Summary
Today `SandboxPermissions::requires_additional_permissions()` does not
actually mean "is `WithAdditionalPermissions`". It returns `true` for
any non-default sandbox override, including `RequireEscalated`. That
broad behavior is relied on in multiple `main` callsites.
The naming is security-sensitive because `SandboxPermissions` is used on
shell-like tool calls to tell the executor how a single command should
relate to the turn sandbox:
- `UseDefault`: run with the turn sandbox unchanged
- `RequireEscalated`: request execution outside the sandbox
- `WithAdditionalPermissions`: stay sandboxed but widen permissions for
that command only
## Problem
The old helper name reads as if it only applies to the
`WithAdditionalPermissions` variant. In practice it means "this command
requested any explicit sandbox override."
That ambiguity made it easy to read production checks incorrectly and
made the guardian change look like a standalone `main` fix when it is
not.
On `main` today:
- `shell` and `unified_exec` intentionally reject any explicit
`sandbox_permissions` request unless approval policy is `OnRequest`
- `exec_policy` intentionally treats any explicit sandbox override as
prompt-worthy in restricted sandboxes
- tests intentionally serialize both `RequireEscalated` and
`WithAdditionalPermissions` as explicit sandbox override requests
So changing those callsites from the broad helper to a narrow
`WithAdditionalPermissions` check would be a behavior change, not a pure
cleanup.
## What This PR Does
- documents `SandboxPermissions` as a per-command sandbox override, not
a generic permissions bag
- adds `requests_sandbox_override()` for the broad meaning: anything
except `UseDefault`
- adds `uses_additional_permissions()` for the narrow meaning: only
`WithAdditionalPermissions`
- keeps `requires_additional_permissions()` as a compatibility alias to
the broad meaning for now
- updates the current broad callsites to use the accurately named broad
helper
- adds unit coverage that locks in the semantics of all three helpers
## What This PR Does Not Do
This PR does not change runtime behavior. That is intentional.
