Add a Notes panel to the sidebar for project/repository notes

What variant of Codex are you using?

Codex App / Desktop

What feature would you like to see?

I would like to have a new “Notes” option in the Show/Hide Sidebar area.

The idea is to provide a simple panel where I can write and keep notes related to the current project or repository.

These notes could be used to store information that I want to provide to the agent later, such as:

• technical decisions;
• tasks or ideas to implement later;
• important project information;
• notes about files, bugs, or architecture;
• instructions that I may want to give the agent in a future conversation.

Ideally, the notes would be persistent and associated with the current project/repository, so they can be viewed and edited directly from the sidebar.

It would also be useful if the agent could read these notes when explicitly requested, for example: “consider the notes for this project.”

This does not need to be a complex documentation system — just a simple, persistent notes editor integrated into the Codex UI.

Additional information

No response

The issue names no files, tests, or entry points; start by locating the Codex App/Desktop sidebar and its project or repository state handling. Clarify how notes persist and how an agent is explicitly asked to read them. Done means a Notes sidebar panel can edit and retain project or repository notes and expose them on request.
