Codex Desktop: Add a one-click “Enhance Prompt” action to the composer

Feature request

Please add a one-click Enhance Prompt action to the Codex Desktop composer, similar to the prompt-refinement button available in some agentic development tools.

Desired workflow

1. The user types a rough, fragmented, or conversational instruction in the composer.
2. The user clicks a sparkle button or presses a configurable keyboard shortcut.
3. Codex rewrites the unsent draft into a clearer, structured coding task.
4. The optimized text replaces the current draft in the composer.
5. The user reviews or edits the result before sending it.

Requirements

• Operates on the current unsent composer draft.
• Does not create a conversation turn or pollute thread history/context.
• Preserves file paths, project names, commands, code snippets, and technical terms.
• Does not invent requirements that were not present in the original text.
• Can use lightweight project context such as AGENTS.md when helpful.
• Provides Undo / Restore Original.
• Supports a configurable keyboard shortcut.
• Optionally offers concise, standard, and detailed refinement modes.
• Works in Codex Desktop and ideally the IDE extension.
• Shows a preview or diff before replacing the original draft.

Why this is useful

Many users enter development instructions in short, fragmented natural language. A lightweight refinement step before submission would reduce ambiguity, reduce back-and-forth, and help lower-cost models execute tasks more reliably.

This is especially useful for users who alternate between high-capability and lower-cost models: prompt refinement can improve execution quality without requiring every task to use the most expensive model.
