[Desktop Remote SSH 26.825.31414] effectful task tools still missing with CLI 0.150.1

What version of the Codex App are you using?

Post-update reproduction:

• ChatGPT / Codex Desktop: 26.825.31414
• About-dialog release date: August 28, 2026
• Remote task session metadata: codex-cli 0.150.1
• Surface: Codex Desktop with a managed Remote SSH Linux project

Pre-update comparison from the same account/remote workflow:

• Desktop: the pre-26.825 build (the exact About-dialog string was not retained in the remote rollout)
• Remote task session metadata: codex-cli 0.149.1
• Result: the same failure

For an exact earlier Desktop/CLI build pair with the same symptom, see #40852: Desktop 26.820.60940 / bundled CLI 0.150.0-alpha.8.

What platform is your computer?

• Desktop controller: macOS
• Execution host: remote Linux over Codex Remote SSH
• Authenticated ChatGPT Codex session

What issue are you seeing?

Updating both the Desktop app and the remote Codex runtime did not restore the effectful first-party task-management tools.

A brand-new Remote SSH task created after installing Desktop 26.825.31414 records cli_version: 0.150.1. Its callable Codex App catalog still contains the read/helper side:

• list_threads
• list_archived_threads
• read_thread
• wait_threads
• title, pin, archive, and share helpers

But the effectful side is still omitted:

• create_thread
• send_message_to_thread
• fork_thread
• handoff_thread
• automation_update

The result is the same fail previously reported in #40865 and #40852: read/list/wait work, while user-authorized creation and inter-task coordination are unavailable.

This is a release-verification follow-up, not a new root-cause claim. The purpose is to record that Desktop 26.825.31414 plus remote CLI/app-server 0.150.1 still reproduces the regression in a fresh post-update task.

Version matrix

The official changelog currently lists CLI 0.150.1 as a remote-compaction fix and does not document a repair for this Desktop task-tool projection issue.

What steps can reproduce the bug?

1. Install ChatGPT / Codex Desktop 26.825.31414.
2. Connect to a managed Remote SSH Linux project.
3. Confirm the remote Codex runtime and new task session metadata report 0.150.1.
4. Create a completely new Desktop task after the update.
5. Inspect the callable Codex App task-tool inventory.
6. Confirm that list_threads, read_thread, and wait_threads are present and callable.
7. Attempt to locate create_thread, send_message_to_thread, fork_thread, or handoff_thread.
8. Observe that those tools are absent, so a standard project-owned task cannot be created or messaged from the source task.

What is the expected behavior?

The Desktop task-tool migration/projection should expose a coherent task-management surface on Remote SSH hosts:

• When read/list/wait tools are available, explicitly user-authorized create/send/fork/handoff tools should also be available through the supported Codex App MCP path.
• A fresh post-update task should be able to create a normal user-owned task inside the selected Desktop project and send it a visible message.
• Desktop instructions must agree with the callable tool catalog.
• If policy intentionally removes a capability, the task should receive a structured diagnostic instead of silently missing only the effectful half of the tool family.

Impact

This prevents normal user-owned multi-task orchestration:

• no project-owned worker/reviewer task creation;
• no visible callback or follow-up message to an existing task;
• no standard fork or handoff lifecycle;
• internal subagents are not an equivalent replacement for separate user-owned Desktop tasks;
• raw app-server fallback creation is not equivalent because it can produce a task with no Desktop project association.

Additional information

• The model configuration is not the failure: gpt-5.6-luna with max reasoning was independently able to complete a direct app-server turn.
• The failing boundary is the Desktop task-tool projection/project orchestration surface.
• No raw task IDs, hostnames, repository contents, credentials, or full rollout logs are included here. Sanitized tool inventories and session metadata can be supplied privately if needed.

Start by tracing the Remote SSH task-tool projection and Codex App MCP catalog for a fresh task, comparing the available read/list/wait tools with create, send, fork, and handoff. Reproduce with Desktop 26.825.31414 and remote CLI 0.150.1. Done means the effectful tools appear coherently, or a structured diagnostic explains their intentional absence.
