Findings

• [Major] collaborationMode is dropped before the runner sees it — the hub now includes collaborationMode in the machine RPC payload, but the CLI machine RPC handler still only destructures and forwards the older fields. A Create Session request with Collaboration = Plan will therefore spawn hapi codex without --collaboration-mode plan, so the new selector has no effect. Evidence: hub/src/sync/rpcGateway.ts:162; receiver context: cli/src/api/apiMachine.ts:262 and cli/src/api/apiMachine.ts:273.
  Suggested fix:

  const { directory, sessionId, resumeSessionId, machineId, approvedNewDirectoryCreation, agent, model, effort, modelReasoningEffort, yolo, permissionMode, serviceTier, collaborationMode, token, sessionType, worktreeName } = params || {}
  
  const result = await spawnSession({
      directory,
      sessionId,
      resumeSessionId,
      machineId,
      approvedNewDirectoryCreation,
      agent,
      model,
      effort,
      modelReasoningEffort,
      yolo,
      permissionMode,
      serviceTier,
      collaborationMode,
      token,
      sessionType,
      worktreeName
  })

Summary

• Review mode: initial
• Found one Major issue in the new spawn plumbing: Plan mode is accepted by web/hub but lost at the CLI machine RPC boundary.

Testing

• Not run (automation; static review only).

HAPI Bot

Findings

• [Minor] Fast mode selection can be reset while the Codex model catalog is still loading — showCodexFastMode is false whenever codexModelsState.models is empty, including the initial load. In the Browse → New Session remount path, the draft restores serviceTier: 'fast', then this effect immediately changes it back to standard before useCodexModels returns, so the spawn payload omits Fast even for models that advertise it. Evidence web/src/components/NewSession/index.tsx:217.
  Suggested fix:

  const hasCodexModelCatalog = codexModelsState.models.length > 0
  
  useEffect(() => {
      if (hasCodexModelCatalog && !showCodexFastMode && serviceTier !== 'standard') {
          setServiceTier('standard')
      }
  }, [hasCodexModelCatalog, showCodexFastMode, serviceTier])

HAPI Bot

Findings

• [Minor] Fast selection can be dropped while the Codex catalog is loading — showCodexFastMode is false while useCodexModels is still loading because the model list is empty, but the Create button remains enabled. A restored Browse draft can already have serviceTier === 'fast'; clicking Create before the catalog settles reaches web/src/components/NewSession/index.tsx:658 with showCodexFastMode === false, so the spawn payload omits serviceTier and starts Standard instead of the restored Fast choice.
  Suggested fix:

  const fastModeSelectionPending = agent === 'codex'
      && serviceTier === 'fast'
      && codexModelsState.isLoading
  
  const canCreate = Boolean(
      machineId
      && trimmedDirectory
      && !isFormDisabled
      && !missingWorktreeDirectory
      && !fastModeSelectionPending
  )

HAPI Bot

Findings

• [Major] Codex import ignores the new Fast/Plan selections — the form now exposes serviceTier and collaborationMode, but the selected-Codex-session branch calls syncCodexSession/resumeSession without either value, so choosing an existing Codex thread and pressing Create silently starts it with the stored/default tier and collaboration mode instead of the visible selections. Evidence: web/src/components/NewSession/index.tsx:769 computes the selected collaboration mode, while the import branch at web/src/components/NewSession/index.tsx:775 only sends model/reasoning/yolo.
  Suggested fix:

  // Include these in CodexDesktopSyncRequest/parseSyncSessionRequest/importSelectedCodexSessions,
  // then persist them on the inactive imported session before resume.
  const result = await props.api.syncCodexSession({
      sessionIds: [selectedCodexImportSession.id],
      cwd: selectedCodexImportSession.cwd ?? trimmedDirectory,
      machineId: codexImportMachineId ?? machineId,
      model: resolvedModel ?? null,
      modelReasoningEffort: resolvedModelReasoningEffort ?? null,
      yolo: yoloMode,
      serviceTier: resolvedServiceTier ?? undefined,
      collaborationMode: resolvedCollaborationMode ?? undefined
  })

Summary

• Reviewed the full current PR diff plus the previous bot review context.
• Found one user-visible gap in the Codex import path for the newly exposed Create Session controls.

Testing

• Not run (automation): PR code treated as untrusted, so this pass did not execute tests.

HAPI Bot

Findings

• [Major] Create Session drops explicit Standard Fast mode — the new selector only forwards a service tier when the value is fast, so choosing/keeping Standard produces undefined instead of the explicit standard sentinel used elsewhere. The Codex app-server mapping documents standard -> null while undefined means “omit; use account default,” and the existing chat setting sends standard through /service-tier. The import route also rejects standard, so fixing the client alone would fail for imported Codex threads. Evidence: web/src/components/NewSession/index.tsx:766, hub/src/web/routes/codexDesktop.ts:1706, related mapping in cli/src/codex/utils/appServerConfig.ts:75.
  Suggested fix:

  const resolvedServiceTier = agent === "codex" && showCodexFastMode
      ? serviceTier
      : undefined
  
  // create spawn
  serviceTier: resolvedServiceTier
  
  // Codex import payload
  serviceTier: resolvedServiceTier
  
  // parseSyncSessionRequest
  if (
      hasServiceTier
      && bodyRecord.serviceTier !== null
      && bodyRecord.serviceTier !== "fast"
      && bodyRecord.serviceTier !== "standard"
  ) {
      return { sessionIds: [], error: "Invalid serviceTier" }
  }

Questions

• None.

Summary

• Review mode: follow-up after new commits
• Reviewed the full current PR diff plus the previous bot review context. The prior import Fast/Plan gap is addressed, but the new Standard Fast-mode path is still not wired as an explicit selection.

Testing

• Not run (automation). Suggested coverage: Create Codex session with Fast Mode = Standard forwards serviceTier: "standard"; Codex import accepts/applies serviceTier: "standard".

HAPI Bot

Findings

Questions

Summary

• Review mode: follow-up after new commits
• Reviewed the full current PR diff at d31312b plus the prior HAPI Bot review. The prior explicit standard service-tier gap is addressed in the follow-up diff. Residual risk: no browser/component test covers the full Create Session submit path for Fast/Plan selectors.

Testing

• Not run (automation).
