codex - 💡(How to fix) Fix Add an option to disable automatic conversion of long pasted prompts into .txt attachments

What variant of Codex are you using?

Codex App on macOS, desktop app

What feature would you like to see?

I would like Codex App to add an option to disable automatic conversion of long pasted prompts into .txt attachments.

Recently, when I paste a long structured prompt into Codex App, the prompt is no longer inserted into the text input as normal text. Instead, it is automatically converted into a .txt attachment.

This is very disruptive for coding workflows.

My workflow depends on pasting long implementation prompts directly into Codex. These prompts are not documents for analysis. They are the actual instructions for the agent. When Codex silently converts them into file attachments, the interaction model changes: I now have to add extra instructions like “read the attached txt file as the prompt,” and I can no longer rely on the pasted text being treated as the active instruction in the same way as before.

Expected behavior:

• Pasted text should remain pasted text by default.
• If Codex wants to offer attachment conversion for very long pastes, it should be optional.
• There should be a setting such as: “Auto-convert long pasted text to attachments: On / Off”
• Alternatively, there should be a visible button: “Paste as text” / “Convert back to text field”

Actual behavior:

• Long pasted prompts are automatically converted into .txt attachments.
• There is no obvious setting to disable this.
• This makes long structured prompt workflows slower, less predictable, and more error-prone.

Why this matters: For many coding tasks, especially multi-step implementation tasks, the prompt itself is the primary instruction. Treating it as an attachment is not equivalent to pasting it as text. It adds friction and makes Codex feel less reliable for complex coding workflows.

Please either restore the previous paste behavior or add an opt-out setting for this automatic conversion.
