macOS Desktop 26.908.40834: Rename dialog no longer offers an AI-generated title suggestion

Summary

On the macOS Codex desktop app, opening Rename for an existing local task now only shows its current title and Cancel/Save buttons. The user reports previously receiving an AI-generated suggestion when opening Rename. The previous working version is unknown.

This report concerns the macOS desktop Rename dialog, not the CLI /rename command or VS Code extension.

Environment

• macOS 26.5.2, Apple Silicon
• Desktop version: 26.908.40834 (8881)
• Bundle ID: com.openai.codex
• Developer ID: OpenAI OpCo, LLC (2DC432GLL2)
• Deep/strict code-signature verification passes
• app.asar SHA-256: bb40cd8811887363104a19291346af9595632e0e956316a1086b274fb8e3eafc
• UI language: Simplified Chinese

Steps and observed behavior

1. Open an existing local Codex task.
2. Select Rename.
3. The dialog displays the current title, a subtitle equivalent to "Keep it short and recognizable", and Cancel/Save buttons.
4. No AI title suggestion control is visible. The user reports that the previous automatic suggestion behavior is absent.

Expected behavior

Restore the ability to obtain an editable, conversation-based title suggestion directly in the desktop Rename dialog. If this capability was intentionally moved or removed, document its supported replacement and any relevant settings.

Read-only diagnostic evidence

In the signed installed bundle, webview/assets/app-primary-44ec287874b7.js contains the shared Rename wrapper lU and component T2t. The component initializes the input from initialValue, renders the input (optionally with an emoji picker), and provides Cancel/Save. Inspection of the complete component found no title-suggestion request or generation effect when opening the dialog.

The separate new-task title generation path is still present in app-initial-9b95fa538c62.js. That does not establish a generation path for the existing-task Rename dialog.

No corresponding AI-rename preference was found in the packaged settings search catalog or inspected local title/rename configuration keys. The installed app and user configuration have not been modified to test speculative fixes.

Evidence boundary: the UI observation comes from the user's screenshot and report; the additional inspection is static analysis of the installed signed bundle. Automated interaction with Codex itself was unavailable. A previous working bundle has not been compared.

Related but distinct

PR https://github.com/openai/codex/pull/40495 explicitly adds conversation-based suggestions to the TUI /rename prompt. It does not explain the desktop dialog's current behavior.

The desktop 26.908 release notes at https://learn.chatgpt.com/docs/changelog do not mention this specific change.

Could a maintainer confirm whether this is an intentional desktop change or a regression, whether a supported setting restores it, and which desktop build provides the intended behavior?

Start by inspecting the bundled webview component T2t and shared Rename wrapper lU in webview/assets/app-primary-44ec287874b7.js, then compare the desktop behavior with the separate title-generation path in app-initial-9b95fa538c62.js. Establish whether the missing suggestion is an intentional change or a regression; done means restoring an editable conversation-based suggestion in the desktop dialog or documenting the supported replacement and settings.
