Codex VSCode Extension - How to name/rename a task?

I still think you are on the right track.

I would only add a caution: making changes to the .codex directory without fully understanding the consequences can be disastrous, including the possible loss of all sessions visible in the Codex interface.

Also, the structure of the .codex directory is not something I would treat as stable. Its location, layout, file formats, and even embedded technologies such as SQLite may change over time.

Personally, I would not trust those kinds of changes to a prompt, or even to generated code, I would only do them as a manual process. That is why the first thing I did with your prompt was to walk through the steps by hand.
