  • Add request permissions tool (#13092)
    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.
  • [app-server] Support hot-reload user config when batch writing config. (#13839)
    - [x] Support hot-reload user config when batch writing config.
  • app-server: require absolute cwd for windowsSandbox/setupStart (#13833)
    ## Summary
    - require windowsSandbox/setupStart.cwd to be an AbsolutePathBuf
    - reject relative cwd values at request parsing instead of normalizing
    them later in the setup flow
    - add RPC-layer coverage for relative cwd rejection and update the
    checked-in protocol schemas/docs
    
    ## Why
    windowsSandbox/setupStart was carrying the client-provided cwd as a raw
    PathBuf for command_cwd while config derivation normalized the same
    value into an absolute policy_cwd.
    
    That left room for relative-path ambiguity in the setup path, especially
    for inputs like cwd: "repo". Making the RPC accept only absolute paths
    removes that split entirely: the handler now receives one
    already-validated absolute path and uses it for both config derivation
    and setup.
    
    This keeps the trust model unchanged. Trusted clients could already
    choose the session cwd; this change is only about making the setup RPC
    reject relative paths so command_cwd and policy_cwd cannot diverge.
    
    ## Testing
    - cargo test -p codex-app-server windows_sandbox_setup (run locally by
    user)
    - cargo test -p codex-app-server-protocol windows_sandbox (run locally
    by user)
  • app-server: Add streaming and tty/pty capabilities to command/exec (#13640)
    * Add an ability to stream stdin, stdout, and stderr
    * Streaming of stdout and stderr has a configurable cap for total amount
    of transmitted bytes (with an ability to disable it)
    * Add support for overriding environment variables
    * Add an ability to terminate running applications (using
    `command/exec/terminate`)
    * Add TTY/PTY support, with an ability to resize the terminal (using
    `command/exec/resize`)
  • feat: Add curated plugin marketplace + Metadata Cleanup. (#13712)
    1. Add a synced curated plugin marketplace and include it in marketplace
    discovery.
    2. Expose optional plugin.json interface metadata in plugin/list
    3. Tighten plugin and marketplace path handling using validated absolute
    paths.
    4. Let manifests override skill, MCP, and app config paths.
    5. Restrict plugin enablement/config loading to the user config layer so
    plugin enablement is at global level
  • feat: structured plugin parsing (#13711)
    #### 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.
  • check app auth in plugin/install (#13685)
    #### What
    on `plugin/install`, check if installed apps are already authed on
    chatgpt, and return list of all apps that are not. clients can use this
    list to trigger auth workflows as needed.
    
    checks are best effort based on `codex_apps` loading, much like
    `app/list`.
    
    #### Tests
    Added integration tests, tested locally.
  • support plugin/list. (#13540)
    Introduce a plugin/list which reads from local marketplace.json.
    Also update the signature for plugin/install.
  • feat(app-server): support mcp elicitations in v2 api (#13425)
    This adds a first-class server request for MCP server elicitations:
    `mcpServer/elicitation/request`.
    
    Until now, MCP elicitation requests only showed up as a raw
    `codex/event/elicitation_request` event from core. That made it hard for
    v2 clients to handle elicitations using the same request/response flow
    as other server-driven interactions (like shell and `apply_patch`
    tools).
    
    This also updates the underlying MCP elicitation request handling in
    core to pass through the full MCP request (including URL and form data)
    so we can expose it properly in app-server.
    
    ### Why not `item/mcpToolCall/elicitationRequest`?
    This is because MCP elicitations are related to MCP servers first, and
    only optionally to a specific MCP tool call.
    
    In the MCP protocol, elicitation is a server-to-client capability: the
    server sends `elicitation/create`, and the client replies with an
    elicitation result. RMCP models it that way as well.
    
    In practice an elicitation is often triggered by an MCP tool call, but
    not always.
    
    ### What changed
    - add `mcpServer/elicitation/request` to the v2 app-server API
    - translate core `codex/event/elicitation_request` events into the new
    v2 server request
    - map client responses back into `Op::ResolveElicitation` so the MCP
    server can continue
    - update app-server docs and generated protocol schema
    - add an end-to-end app-server test that covers the full round trip
    through a real RMCP elicitation flow
    - The new test exercises a realistic case where an MCP tool call
    triggers an elicitation, the app-server emits
    mcpServer/elicitation/request, the client accepts it, and the tool call
    resumes and completes successfully.
    
    ### app-server API flow
    - Client starts a thread with `thread/start`.
    - Client starts a turn with `turn/start`.
    - App-server sends `item/started` for the `mcpToolCall`.
    - While that tool call is in progress, app-server sends
    `mcpServer/elicitation/request`.
    - Client responds to that request with `{ action: "accept" | "decline" |
    "cancel" }`.
    - App-server sends `serverRequest/resolved`.
    - App-server sends `item/completed` for the mcpToolCall.
    - App-server sends `turn/completed`.
    - If the turn is interrupted while the elicitation is pending,
    app-server still sends `serverRequest/resolved` before the turn
    finishes.
  • plugin: support local-based marketplace.json + install endpoint. (#13422)
    Support marketplace.json that points to a local file, with
    ```
        "source":
        {
            "source": "local",
            "path": "./plugin-1"
        },
     ```
     
     Add a new plugin/install endpoint which add the plugin to the cache folder and enable it in config.toml.
  • allow apps to specify cwd for sandbox setup. (#13484)
    The electron app doesn't start up the app-server in a particular
    workspace directory.
    So sandbox setup happens in the app-installed directory instead of the
    project workspace.
    
    This allows the app do specify the workspace cwd so that the sandbox
    setup actually sets up the ACLs instead of exiting fast and then having
    the first shell command be slow.
  • chore: Nest skill and protocol network permissions under network.enabled (#13427)
    ## Summary
    
    Changes the permission profile shape from a bare network boolean to a
    nested object.
    
    Before:
    
    ```yaml
    permissions:
      network: true
    ```
    
    After:
    
    ```yaml
    permissions:
      network:
        enabled: true
    ```
    
    This also updates the shared Rust and app-server protocol types so
    `PermissionProfile.network` is no longer `Option<bool>`, but
    `Option<NetworkPermissions>` with `enabled: Option<bool>`.
    
    ## What Changed
    
    - Updated `PermissionProfile` in `codex-rs/protocol/src/models.rs`:
    - `pub network: Option<bool>` -> `pub network:
    Option<NetworkPermissions>`
    - Added `NetworkPermissions` with:
      - `pub enabled: Option<bool>`
    - Changed emptiness semantics so `network` is only considered empty when
    `enabled` is `None`
    - Updated skill metadata parsing to accept `permissions.network.enabled`
    - Updated core permission consumers to read
    `network.enabled.unwrap_or(false)` where a concrete boolean is needed
    - Updated app-server v2 protocol types and regenerated schema/TypeScript
    outputs
    - Updated docs to mention `additionalPermissions.network.enabled`
  • config: enforce enterprise feature requirements (#13388)
    ## Why
    
    Enterprises can already constrain approvals, sandboxing, and web search
    through `requirements.toml` and MDM, but feature flags were still only
    configurable as managed defaults. That meant an enterprise could suggest
    feature values, but it could not actually pin them.
    
    This change closes that gap and makes enterprise feature requirements
    behave like the other constrained settings. The effective feature set
    now stays consistent with enterprise requirements during config load,
    when config writes are validated, and when runtime code mutates feature
    flags later in the session.
    
    It also tightens the runtime API for managed features. `ManagedFeatures`
    now follows the same constraint-oriented shape as `Constrained<T>`
    instead of exposing panic-prone mutation helpers, and production code
    can no longer construct it through an unconstrained `From<Features>`
    path.
    
    The PR also hardens the `compact_resume_fork` integration coverage on
    Windows. After the feature-management changes,
    `compact_resume_after_second_compaction_preserves_history` was
    overflowing the libtest/Tokio thread stacks on Windows, so the test now
    uses an explicit larger-stack harness as a pragmatic mitigation. That
    may not be the ideal root-cause fix, and it merits a parallel
    investigation into whether part of the async future chain should be
    boxed to reduce stack pressure instead.
    
    ## What Changed
    
    Enterprises can now pin feature values in `requirements.toml` with the
    requirements-side `features` table:
    
    ```toml
    [features]
    personality = true
    unified_exec = false
    ```
    
    Only canonical feature keys are allowed in the requirements `features`
    table; omitted keys remain unconstrained.
    
    - Added a requirements-side pinned feature map to
    `ConfigRequirementsToml`, threaded it through source-preserving
    requirements merge and normalization in `codex-config`, and made the
    TOML surface use `[features]` (while still accepting legacy
    `[feature_requirements]` for compatibility).
    - Exposed `featureRequirements` from `configRequirements/read`,
    regenerated the JSON/TypeScript schema artifacts, and updated the
    app-server README.
    - Wrapped the effective feature set in `ManagedFeatures`, backed by
    `ConstrainedWithSource<Features>`, and changed its API to mirror
    `Constrained<T>`: `can_set(...)`, `set(...) -> ConstraintResult<()>`,
    and result-returning `enable` / `disable` / `set_enabled` helpers.
    - Removed the legacy-usage and bulk-map passthroughs from
    `ManagedFeatures`; callers that need those behaviors now mutate a plain
    `Features` value and reapply it through `set(...)`, so the constrained
    wrapper remains the enforcement boundary.
    - Removed the production loophole for constructing unconstrained
    `ManagedFeatures`. Non-test code now creates it through the configured
    feature-loading path, and `impl From<Features> for ManagedFeatures` is
    restricted to `#[cfg(test)]`.
    - Rejected legacy feature aliases in enterprise feature requirements,
    and return a load error when a pinned combination cannot survive
    dependency normalization.
    - Validated config writes against enterprise feature requirements before
    persisting changes, including explicit conflicting writes and
    profile-specific feature states that normalize into invalid
    combinations.
    - Updated runtime and TUI feature-toggle paths to use the constrained
    setter API and to persist or apply the effective post-constraint value
    rather than the requested value.
    - Updated the `core_test_support` Bazel target to include the bundled
    core model-catalog fixtures in its runtime data, so helper code that
    resolves `core/models.json` through runfiles works in remote Bazel test
    environments.
    - Renamed the core config test coverage to emphasize that effective
    feature values are normalized at runtime, while conflicting persisted
    config writes are rejected.
    - Ran `compact_resume_after_second_compaction_preserves_history` inside
    an explicit 8 MiB test thread and Tokio runtime worker stack, following
    the existing larger-stack integration-test pattern, to keep the Windows
    `compact_resume_fork` test slice from aborting while a parallel
    investigation continues into whether some of the underlying async
    futures should be boxed.
    
    ## Verification
    
    - `cargo test -p codex-config`
    - `cargo test -p codex-core feature_requirements_ -- --nocapture`
    - `cargo test -p codex-core
    load_requirements_toml_produces_expected_constraints -- --nocapture`
    - `cargo test -p codex-core
    compact_resume_after_second_compaction_preserves_history -- --nocapture`
    - `cargo test -p codex-core compact_resume_fork -- --nocapture`
    - Re-ran the built `codex-core` `tests/all` binary with
    `RUST_MIN_STACK=262144` for
    `compact_resume_after_second_compaction_preserves_history` to confirm
    the explicit-stack harness fixes the deterministic low-stack repro.
    - `cargo test -p codex-core`
    - This still fails locally in unrelated integration areas that expect
    the `codex` / `test_stdio_server` binaries or hit existing `search_tool`
    wiremock mismatches.
    
    ## Docs
    
    `developers.openai.com/codex` should document the requirements-side
    `[features]` table for enterprise and MDM-managed configuration,
    including that it only accepts canonical feature keys and that
    conflicting config writes are rejected.
  • feat(app-server): add a skills/changed v2 notification (#13414)
    This adds a first-class app-server v2 `skills/changed` notification for
    the existing skills live-reload signal.
    
    Before this change, clients only had the legacy raw
    `codex/event/skills_update_available` event. With this PR, v2 clients
    can listen for a typed JSON-RPC notification instead of depending on the
    legacy `codex/event/*` stream, which we want to remove soon.
  • Add thread metadata update endpoint to app server (#13280)
    ## Summary
    - add the v2 `thread/metadata/update` API, including
    protocol/schema/TypeScript exports and app-server docs
    - patch stored thread `gitInfo` in sqlite without resuming the thread,
    with validation plus support for explicit `null` clears
    - repair missing sqlite thread rows from rollout data before patching,
    and make those repairs safe by inserting only when absent and updating
    only git columns so newer metadata is not clobbered
    - keep sqlite authoritative for mutable thread git metadata by
    preserving existing sqlite git fields during reconcile/backfill and only
    using rollout `SessionMeta` git fields to fill gaps
    - add regression coverage for the endpoint, repair paths, concurrent
    sqlite writes, clearing git fields, and rollout/backfill reconciliation
    - fix the login server shutdown race so cancelling before the waiter
    starts still terminates `block_until_done()` correctly
    
    ## Testing
    - `cargo test -p codex-state
    apply_rollout_items_preserves_existing_git_branch_and_fills_missing_git_fields`
    - `cargo test -p codex-state
    update_thread_git_info_preserves_newer_non_git_metadata`
    - `cargo test -p codex-core
    backfill_sessions_preserves_existing_git_branch_and_fills_missing_git_fields`
    - `cargo test -p codex-app-server thread_metadata_update`
    - `cargo test`
    - currently fails in existing `codex-core` grep-files tests with
    `unsupported call: grep_files`:
        - `suite::grep_files::grep_files_tool_collects_matches`
        - `suite::grep_files::grep_files_tool_reports_empty_results`
  • app-server: Silence thread status changes caused by thread being created (#13079)
    Currently we emit `thread/status/changed` with `Idle` status right
    before sending `thread/started` event (which also has `Idle` status in
    it).
    It feels that there is no point in that as client has no way to know
    prior state of the thread as it didn't exist yet, so silence these kinds
    of notifications.
  • fix(app-server): emit turn/started only when turn actually starts (#13261)
    This is a follow-up for https://github.com/openai/codex/pull/13047
    
    ## Why
    We had a race where `turn/started` could be observed before the thread
    had actually transitioned to `Active`. This was because we eagerly
    emitted `turn/started` in the request handler for `turn/start` (and
    `review/start`).
    
    That was showing up as flaky `thread/resume` tests, but the real issue
    was broader: a client could see `turn/started` and still get back an
    idle thread immediately afterward.
    
    The first idea was to eagerly call
    `thread_watch_manager.note_turn_started(...)` from the `turn/start`
    request path. That turns out to be unsafe, because
    `submit(Op::UserInput)` only queues work. If a turn starts and completes
    quickly, request-path bookkeeping can race with the real lifecycle
    events and leave stale running state behind.
    
    **The real fix** is to move `turn/started` to emit only after the turn
    _actually_ starts, so we do that by waiting for the
    `EventMsg::TurnStarted` notification emitted by codex core. We do this
    for both `turn/start` and `review/start`.
    
    I also verified this change is safe for our first-party codex apps -
    they don't have any assumptions that `turn/started` is emitted before
    the RPC response to `turn/start` (which is correct anyway).
    
    I also removed `single_client_mode` since it isn't really necessary now.
    
    ## Testing
    - `cargo test -p codex-app-server thread_resume -- --nocapture`
    - `cargo test -p codex-app-server
    'suite::v2::turn_start::turn_start_emits_notifications_and_accepts_model_override'
    -- --exact --nocapture`
    - `cargo test -p codex-app-server`
  • app-server: Update thread/name/set to support not-loaded threads (#13282)
    Currently `thread/name/set` does only work for loaded threads.
    Expand the scope to also support persisted but not-yet-loaded ones for a
    more predictable API surface.
    This will make it possible to rename threads discovered via
    `thread/list` and similar operations.
  • [codex] include plan type in account updates (#13181)
    This change fixes a Codex app account-state sync bug where clients could
    know the user was signed in but still miss the ChatGPT subscription
    tier, which could lead to incorrect upgrade messaging for paid users.
    
    The root cause was that `account/updated` only carried `authMode` while
    plan information was available separately via `account/read` and
    rate-limit snapshots, so this update adds `planType` to
    `account/updated`, populates it consistently across login and refresh
    paths.
  • app-server: Add ephemeral field to Thread object (#13084)
    Currently there is no alternative way to know that thread is ephemeral,
    only client which did create it has the knowledge.
  • app-server: Replay pending item requests on thread/resume (#12560)
    Replay pending client requests after `thread/resume` and emit resolved
    notifications when those requests clear so approval/input UI state stays
    in sync after reconnects and across subscribed clients.
    
    Affected RPCs:
    - `item/commandExecution/requestApproval`
    - `item/fileChange/requestApproval`
    - `item/tool/requestUserInput`
    
    Motivation:
    - Resumed clients need to see pending approval/input requests that were
    already outstanding before the reconnect.
    - Clients also need an explicit signal when a pending request resolves
    or is cleared so stale UI can be removed on turn start, completion, or
    interruption.
    
    Implementation notes:
    - Use pending client requests from `OutgoingMessageSender` in order to
    replay them after `thread/resume` attaches the connection, using
    original request ids.
    - Emit `serverRequest/resolved` when pending requests are answered
    or cleared by lifecycle cleanup.
    - Update the app-server protocol schema, generated TypeScript bindings,
    and README docs for the replay/resolution flow.
    
    High-level test plan:
    - Added automated coverage for replaying pending command execution and
    file change approval requests on `thread/resume`.
    - Added automated coverage for resolved notifications in command
    approval, file change approval, request_user_input, turn start, and turn
    interrupt flows.
    - Verified schema/docs updates in the relevant protocol and app-server
    tests.
    
    Manual testing:
    - Tested reconnect/resume with multiple connections.
    - Confirmed state stayed in sync between connections.
  • fix: use AbsolutePathBuf for permission profile file roots (#12970)
    ## Why
    `PermissionProfile` should describe filesystem roots as absolute paths
    at the type level. Using `PathBuf` in `FileSystemPermissions` made the
    shared type too permissive and blurred together three different
    deserialization cases:
    
    - skill metadata in `agents/openai.yaml`, where relative paths should
    resolve against the skill directory
    - app-server API payloads, where callers should have to send absolute
    paths
    - local tool-call payloads for commands like `shell_command` and
    `exec_command`, where `additional_permissions.file_system` may
    legitimately be relative to the command `workdir`
    
    This change tightens the shared model without regressing the existing
    local command flow.
    
    ## What Changed
    - changed `protocol::models::FileSystemPermissions` and the app-server
    `AdditionalFileSystemPermissions` mirror to use `AbsolutePathBuf`
    - wrapped skill metadata deserialization in `AbsolutePathBufGuard`, so
    relative permission roots in `agents/openai.yaml` resolve against the
    containing skill directory
    - kept app-server/API deserialization strict, so relative
    `additionalPermissions.fileSystem.*` paths are rejected at the boundary
    - restored cwd/workdir-relative deserialization for local tool-call
    payloads by parsing `shell`, `shell_command`, and `exec_command`
    arguments under an `AbsolutePathBufGuard` rooted at the resolved command
    working directory
    - simplified runtime additional-permission normalization so it only
    canonicalizes and deduplicates absolute roots instead of trying to
    recover relative ones later
    - updated the app-server schema fixtures, `app-server/README.md`, and
    the affected transport/TUI tests to match the final behavior
  • Add model availability NUX metadata (#12972)
    - replace show_nux with structured availability_nux model metadata
    - expose availability NUX data through the app-server model API
    - update shared fixtures and tests for the new field
  • Feat: cxa-1833 update model/list (#12958)
    ### Summary
    Update `model/list` in app server to include more upgrade information.
  • feat: include available decisions in command approval requests (#12758)
    Command-approval clients currently infer which choices to show from
    side-channel fields like `networkApprovalContext`,
    `proposedExecpolicyAmendment`, and `additionalPermissions`. That makes
    the request shape harder to evolve, and it forces each client to
    replicate the server's heuristics instead of receiving the exact
    decision list for the prompt.
    
    This PR introduces a mapping between `CommandExecutionApprovalDecision`
    and `codex_protocol::protocol::ReviewDecision`:
    
    ```rust
    impl From<CoreReviewDecision> for CommandExecutionApprovalDecision {
        fn from(value: CoreReviewDecision) -> Self {
            match value {
                CoreReviewDecision::Approved => Self::Accept,
                CoreReviewDecision::ApprovedExecpolicyAmendment {
                    proposed_execpolicy_amendment,
                } => Self::AcceptWithExecpolicyAmendment {
                    execpolicy_amendment: proposed_execpolicy_amendment.into(),
                },
                CoreReviewDecision::ApprovedForSession => Self::AcceptForSession,
                CoreReviewDecision::NetworkPolicyAmendment {
                    network_policy_amendment,
                } => Self::ApplyNetworkPolicyAmendment {
                    network_policy_amendment: network_policy_amendment.into(),
                },
                CoreReviewDecision::Abort => Self::Cancel,
                CoreReviewDecision::Denied => Self::Decline,
            }
        }
    }
    ```
    
    And updates `CommandExecutionRequestApprovalParams` to have a new field:
    
    ```rust
    available_decisions: Option<Vec<CommandExecutionApprovalDecision>>
    ```
    
    when, if specified, should make it easier for clients to display an
    appropriate list of options in the UI.
    
    This makes it possible for `CoreShellActionProvider::prompt()` in
    `unix_escalation.rs` to specify the `Vec<ReviewDecision>` directly,
    adding support for `ApprovedForSession` when approving a skill script,
    which was previously missing in the TUI.
    
    Note this results in a significant change to `exec_options()` in
    `approval_overlay.rs`, as the displayed options are now derived from
    `available_decisions: &[ReviewDecision]`.
    
    ## What Changed
    
    - Add `available_decisions` to
    [`ExecApprovalRequestEvent`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/protocol/src/approvals.rs#L111-L175),
    including helpers to derive the legacy default choices when older
    senders omit the field.
    - Map `codex_protocol::protocol::ReviewDecision` to app-server
    `CommandExecutionApprovalDecision` and expose the ordered list as
    experimental `availableDecisions` in
    [`CommandExecutionRequestApprovalParams`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/app-server-protocol/src/protocol/v2.rs#L3798-L3807).
    - Thread optional `available_decisions` through the core approval path
    so Unix shell escalation can explicitly request `ApprovedForSession` for
    session-scoped approvals instead of relying on client heuristics.
    [`unix_escalation.rs`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/core/src/tools/runtimes/shell/unix_escalation.rs#L194-L214)
    - Update the TUI approval overlay to build its buttons from the ordered
    decision list, while preserving the legacy fallback when
    `available_decisions` is missing.
    - Update the app-server README, test client output, and generated schema
    artifacts to document and surface the new field.
    
    ## Testing
    
    - Add `approval_overlay.rs` coverage for explicit decision lists,
    including the generic `ApprovedForSession` path and network approval
    options.
    - Update `chatwidget/tests.rs` and app-server protocol tests to populate
    the new optional field and keep older event shapes working.
    
    ## Developers Docs
    
    - If we document `item/commandExecution/requestApproval` on
    [developers.openai.com/codex](https://developers.openai.com/codex), add
    experimental `availableDecisions` as the preferred source of approval
    choices and note that older servers may omit it.
  • Enable request_user_input in Default mode (#12735)
    ## Summary
    - allow `request_user_input` in Default collaboration mode as well as
    Plan
    - update the Default-mode instructions to prefer assumptions first and
    use `request_user_input` only when a question is unavoidable
    - update request_user_input and app-server tests to match the new
    Default-mode behavior
    - refactor collaboration-mode availability plumbing into
    `CollaborationModesConfig` for future mode-related flags
    
    ## Codex author

  • feat(app-server): thread/unsubscribe API (#10954)
    Adds a new v2 app-server API for a client to be able to unsubscribe to a
    thread:
    - New RPC method: `thread/unsubscribe`
    - New server notification: `thread/closed`
    
    Today clients can start/resume/archive threads, but there wasn’t a way
    to explicitly unload a live thread from memory without archiving it.
    With `thread/unsubscribe`, a client can indicate it is no longer
    actively working with a live Thread. If this is the only client
    subscribed to that given thread, the thread will be automatically closed
    by app-server, at which point the server will send `thread/closed` and
    `thread/status/changed` with `status: notLoaded` notifications.
    
    This gives clients a way to prevent long-running app-server processes
    from accumulating too many thread (and related) objects in memory.
    
    Closed threads will also be removed from `thread/loaded/list`.
  • feat(app-server): add ThreadItem::DynamicToolCall (#12732)
    Previously, clients would call `thread/start` with dynamic_tools set,
    and when a model invokes a dynamic tool, it would just make the
    server->client `item/tool/call` request and wait for the client's
    response to complete the tool call. This works, but it doesn't have an
    `item/started` or `item/completed` event.
    
    Now we are doing this:
    - [new] emit `item/started` with `DynamicToolCall` populated with the
    call arguments
    - send an `item/tool/call` server request
    - [new] once the client responds, emit `item/completed` with
    `DynamicToolCall` populated with the response.
    
    Also, with `persistExtendedHistory: true`, dynamic tool calls are now
    reconstructable in `thread/read` and `thread/resume` as
    `ThreadItem::DynamicToolCall`.
  • Add app-server v2 thread realtime API (#12715)
    Add experimental `thread/realtime/*` v2 requests and notifications, then
    route app-server realtime events through that thread-scoped surface with
    integration coverage.

  • Support external agent config detect and import (#12660)
    Migration Behavior
    
    * Config
      *  Migrates settings.json into config.toml
    * Only adds fields when config.toml is missing, or when those fields are
    missing from the existing file
      *  Supported mappings:
        env -> shell_environment_policy
         sandbox.enabled = true -> sandbox_mode = "workspace-write"
    
    * Skills
      *  Copies home and repo .claude/skills into .agents/skills
      *  Existing skill directories are not overwritten
      *  SKILL.md content is rewritten from Claude-related terms to Codex
    
    * AgentsMd
      *  Repo only
      *  Migrates CLAUDE.md into AGENTS.md
    * Detect/import only proceed when AGENTS.md is missing or present but
    empty
      *  Content is rewritten from Claude-related terms to Codex
  • feat: add search term to thread list (#12578)
    Add `searchTerm` to `thread/list` that will search for a match in the
    titles (the condition being `searchTerm` $$\in$$ `title`)
  • feat: add service name to app-server (#12319)
    Add service name to the app-server so that the app can use it's own
    service name
    
    This is on thread level because later we might plan the app-server to
    become a singleton on the computer
  • feat(ui): add network approval persistence plumbing (#12358)
    ## Summary
    - add TUI approval options for persistent network host rules
    - add app-server v2 approval payload plumbing for network approval
    context + proposed network policy amendments
    - add app-server handling to translate `applyNetworkPolicyAmendment`
    decisions back into core review decisions
    - update docs/test client output and generated app-server schemas/types
  • feat: add experimental additionalPermissions to v2 command execution approval requests (#12737)
    This adds additionalPermissions to the app-server v2
    item/commandExecution/requestApproval payload as an experimental field.
    
    The field is now exposed on CommandExecutionRequestApprovalParams and is
    populated from the existing core approval event when a command requests
    additional sandbox permissions.
    
    This PR also contains changes to make server requests to support
    experiment API.
    
    A real app server test client test:

  • Add ability to attach extra files to feedback (#12370)
    Allow clients to provide extra files.
  • Refactor network approvals to host/protocol/port scope (#12140)
    ## Summary
    Simplify network approvals by removing per-attempt proxy correlation and
    moving to session-level approval dedupe keyed by (host, protocol, port).
    Instead of encoding attempt IDs into proxy credentials/URLs, we now
    treat approvals as a destination policy decision.
    
    - Concurrent calls to the same destination share one approval prompt.
    - Different destinations (or same host on different ports) get separate
    prompts.
    - Allow once approves the current queued request group only.
    - Allow for session caches that (host, protocol, port) and auto-allows
    future matching requests.
    - Never policy continues to deny without prompting.
    
    Example:
    - 3 calls: 
      - a.com (line 443)
      - b.com (line 443)
      - a.com (line 443)
    => 2 prompts total (a, b), second a waits on the first decision.
    - a.com:80 is treated separately from a.com line 443
    
    ## Testing
    - `just fmt` (in `codex-rs`)
    - `cargo test -p codex-core tools::network_approval::tests`
    - `cargo test -p codex-core` (unit tests pass; existing
    integration-suite failures remain in this environment)
  • app-server: add JSON tracing logs (#12287)
    - add `LOG_FORMAT=json` support for app-server tracing logs via

  • feat: add nick name to sub-agents (#12320)
    Adding random nick name to sub-agents. Used for UX
    
    At the same time, also storing and wiring the role of the sub-agent
  • app-server: expose loaded thread status via read/list and notifications (#11786)
    Motivation
    - Today, a newly connected client has no direct way to determine the
    current runtime status of threads from read/list responses alone.
    - This forces clients to infer state from transient events, which can
    lead to stale or inconsistent UI when reconnecting or attaching late.
    
    Changes
    - Add `status` to `thread/read` responses.
    - Add `statuses` to `thread/list` responses.
    - Emit `thread/status/changed` notifications with `threadId` and the new
    status.
    - Track runtime status for all loaded threads and default unknown
    threads to `idle`.
    - Update protocol/docs/tests/schema fixtures for the revised API.
    
    Testing
    - Validated protocol API changes with automated protocol tests and
    regenerated schema/type fixtures.
    - Validated app-server behavior with unit and integration test suites,
    including status transitions and notifications.
  • app-server support for Windows sandbox setup. (#12025)
    app-server support for initiating Windows sandbox setup.
    server responds quickly to setup request and makes a future RPC call
    back to client when the setup finishes.
    
    The TUI implementation is unaffected but in a future PR I'll update the
    TUI to use the shared setup helper
    (`windows_sandbox.run_windows_sandbox_setup`)
  • feat(core): plumb distinct approval ids for command approvals (#12051)
    zsh fork PR stack:
    - https://github.com/openai/codex/pull/12051 👈 
    - https://github.com/openai/codex/pull/12052
    
    With upcoming support for a fork of zsh that allows us to intercept
    `execve` and run execpolicy checks for each subcommand as part of a
    `CommandExecution`, it will be possible for there to be multiple
    approval requests for a shell command like `/path/to/zsh -lc 'git status
    && rg \"TODO\" src && make test'`.
    
    To support that, this PR introduces a new `approval_id` field across
    core, protocol, and app-server so that we can associate approvals
    properly for subcommands.
  • app-server: Emit thread archive/unarchive notifications (#12030)
    * Add v2 server notifications `thread/archived` and `thread/unarchived`
    with a `threadId` payload.
    * Wire new events into `thread/archive` and `thread/unarchive` success
    paths.
    * Update app-server protocol/schema/docs accordingly.

  • Feat: add model reroute notification (#12001)
    ### Summary
    Builiding off
    https://github.com/openai/codex/pull/11964/files/5c75aa7b89a70bc2cc410a6fd238749306ec4c5e#diff-058ae8f109a8b84b4b79bbfa45f522c2233b9d9e139696044ae374d50b6196e0,
    we have created a `model/rerouted` notification that captures the event
    so that consumers can render as expected. Keep the `EventMsg::Warning`
    path in core so that this does not affect TUI rendering.
    
    `model/rerouted` is meant to be generic to account for future usage
    including capacity planning etc.
  • add(core): safety check downgrade warning (#11964)
    Add per-turn notice when a request is downgraded to a fallback model due
    to cyber safety checks.
    
    **Changes**
    
    - codex-api: Emit a ServerModel event based on the openai-model response
    header and/or response payload (SSE + WebSocket), including when the
    model changes mid-stream.
    - core: When the server-reported model differs from the requested model,
    emit a single per-turn warning explaining the reroute to gpt-5.2 and
    directing users to Trusted
        Access verification and the cyber safety explainer.
    - app-server (v2): Surface these cyber model-routing warnings as
    synthetic userMessage items with text prefixed by Warning: (and document
    this behavior).
  • fix: send unfiltered models over model/list (#11793)
    ### What
    to unblock filtering models in VSCE, change `model/list` app-server
    endpoint to send all models + visibility field `showInPicker` so
    filtering can be done in VSCE if desired.
    
    ### Tests
    Updated tests.
