What issue are you seeing?

The Codex App no longer exposes the project/thread coordination tools that used to allow Codex to create a new chat under a specific Codex project.

In this session, the user asked Codex to create a new chat under an existing project. Codex searched for the expected native thread tools, but create_thread, read_thread, list_projects, set_thread_title, and set_thread_archived were not available in the tool surface.

Because those tools were missing, Codex incorrectly attempted a workaround with spawn_agent. That created a child/subagent thread from the current chat instead of a normal project-scoped chat in the requested project. Local thread records confirmed the spawned child inherited the current workspace rather than landing under the target project.

A later retry again searched for the native project/thread tools and still did not find them. Computer Use is also blocked from controlling the Codex app UI directly, so there was no reliable fallback path to create the project chat manually from within Codex.

What steps can reproduce the bug?

What is the expected behavior?

Codex should expose a supported way for the assistant to create a real user-visible chat under a specific existing Codex project when the user explicitly requests it.

Expected behavior:

• Codex can list/select projects.
• Codex can create a new thread targeted to the requested project.
• Codex can read the thread back to verify it actually landed under that project.
• If the create call fails, Codex can detect/report the failure instead of falling back to a subagent thread that appears in the wrong place.

Additional information

This used to work in prior Codex App sessions via native thread tools such as list_projects, create_thread, and read_thread.

The user relies on project-scoped Codex spaces for separate work lanes, so losing this capability is more than cosmetic: it causes work to land in the wrong project and makes sidebar/project organization unreliable.
