📝 WalkthroughWalkthroughCodex Goal support was added end to end. Shared contracts define goal state and events. Providers expose goal operations. WebSocket APIs and reactive client state synchronize goals. Web and mobile composers support Goal commands and status display. ChangesCodex Goal support
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to This PR adds remote Codex Goal controls and live updates, but slow clients can cause Goal events to accumulate without limit, and thread access relies on deployment-level isolation rather than an explicit ownership check.

Reviewed the new Codex Goal service/RPC surface against the Effect service conventions. Two related findings on the new CodexGoalOperationError wrapper: it carries an unstructured message as its only data and the wrapping site derives that message from cause.message while discarding the cause. Everything else (namespace imports at the ProviderService boundary, optional codexGoal adapter capability, environment-based dependency acquisition, test-only service stubs) looks consistent with the conventions.

UI consistency review of the web changes (apps/web/src/components/ChatView.tsx, apps/web/src/state/threads.ts).
The new Goal surface correctly reuses the shared systems — ComposerBannerStack/Alert for the banner and stackedThreadToast for command feedback — and useCodexGoal follows the existing useEnvironmentThread atom pattern. Two issues are specific to the banner the diff adds: an unbounded user-authored description in the composer drawer, and stack ordering that lets a permanent informational banner sit in front of the actionable ones.

One remaining convention issue with CodexGoalOperationError: the wire-visible detail field is populated by copying the provider error's message, and the wrapper's message is then derived from it. Now that operation, threadId, and cause are modelled, detail can be dropped so the message comes only from stable structural attributes and the provider text stays in cause.

One finding: the Goal banner is ordered ahead of the parked-thread banner, which pushes that banner's Wake now / Un-settle button behind the collapsed stack on Codex threads with an active Goal.

One finding: the Goal status enum is rendered directly as user-facing copy in the composer banner and the /goal status toast. Prior findings on banner ordering and description clamping look resolved.

One consistency finding on the new Codex Goal composer banner. Prior notes (status label record, banner ordering behind the actionable parked/woke/branch banners, clamped description) are addressed.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR introduces a cross-cutting native Codex Goal feature with new authenticated WebSocket APIs, provider/session lifecycle behavior, live event synchronization, and web/mobile composer UI. The auth-scope change and broad runtime surface require human review despite the additive contracts and lack of persisted Goal state. You can add or adjust custom eligibility rules. Learn more. |

One finding on the web Goal work: the new send-blocking guard has no matching disabled/reason state, so the composer send button lies about being usable while a /goal command is in flight.

@t3dotgg After watching one of your recent YouTube videos, I wanted to make T3 Code my main interface for coding agents. But I quickly hit one frustrating gap: Goals are one of the Codex features I rely on most, and once a Goal existed, T3 did not expose the controls needed to inspect, steer, pause, resume, or reset it.
I found the original issue #2819, now continued as discussion #6777, and the closed #2877, then implemented the narrowest integration I could: T3 acts only as a remote-capable control surface over Codex App Server's native Goal API. Codex remains the source of truth.
What this adds
Codex threads now expose the complete native Goal lifecycle through the normal conversation composer:
/goal create <objective>thread/goal/setwith the objective and active status/goal statusthread/goal/get/goal steer <objective>thread/goal/setwith the updated objective/goal pausethread/goal/setwith paused status/goal resumethread/goal/setwith active status/goal resetor/goal clearthread/goal/clear/goal <objective>remains a create shorthand. Nativethread/goal/updatedandthread/goal/clearednotifications keep connected clients synchronized while the session is running.The current objective, native status, token usage and budget, and elapsed time are shown when Codex exposes them. The command and status surfaces only appear for Codex.
Architecture
This intentionally takes a narrower approach than #2877: it does not project Goal state into T3's persistence layer. That keeps remote clients synchronized without making T3 compete with Codex as the owner of the state.
Known limitation
When Codex is actively processing a turn while a Goal is active, T3 still shows its existing red stop control. Activating it interrupts the current provider turn only; the native Goal remains active. Changing that shared composer and turn-state behavior would affect more than Goal support, so I deliberately left it unchanged to avoid scope creep.
T3 also does not open Codex's interactive Goal editor.
/goal steer <objective>updates the native objective directly. A broader Goal dashboard or control redesign is out of scope for this PR; the UI is intentionally limited to the existing composer flow and a lightweight status banner or card.UI Changes

Verification
Addresses discussion #6777.
Related: #2819 and #2877.
Implementation and verification were performed with Codex. Additional review and cleanup used Claude Code with Opus 5. Final audit and PR preparation used Codex with GPT-5.6 Sol.
Note
Medium Risk
Adds a new WebSocket RPC and provider-runtime surface (including required ProviderService methods and Codex session runtime Goal APIs). Scope is Codex-only with no persisted Goal state, but it sits on session routing, recovery, and auth scopes.
Overview
Adds a control surface for native Codex Goals without T3 owning or persisting Goal state. Codex App Server remains the source of truth.
Server / provider: Codex session runtime now calls
thread/goal/get|set|clearand mapsthread/goal/updated|clearednotifications into runtime events (child collab chatter is dropped).ProviderServiceroutes get/set/clear with optional session recovery on get; unsupported providers fail validation. New WS RPCs (codex.goal.get/set/clear+subscribe) stream a snapshot then live updates, with a sliding buffer so a late snapshot cannot overwrite a live update. Get is read-scoped; set/clear are operate-scoped. Codex advertises a/goalslash command.Clients: Shared
/goalparsing (status, create/steer, pause/resume, clear/reset, and/goal <objective>shorthand) intercepts send on web and mobile instead of posting a message. Active Goals show as a composer banner (web) or card (mobile) with status, objective, and usage. Subscriptions are keyed per environment+thread and refresh after mutations.Reviewed by Cursor Bugbot for commit 5246dfd. Bugbot is set up for automated code reviews on this repo. Configure here.
