Add interactive session-management for Codex CLI:

What feature would you like to see?

I’d like to add a first-class session management experience in the Codex CLI that behaves similarly to how tmux handles sessions — enabling users to maintain multiple independent conversations (sessions), quickly switch between them, rename them, list them, and delete or create new ones — all from within the interactive TUI (and optionally via CLI subcommands).

Specifically:

• /session — displays all saved/resumable sessions, showing metadata such as _alias/name_, _session ID_, _last activity timestamp_, _directory/project context_. It'll be interactive and the user can select to jump to a new session.
• /session rename <SESSION_ID|NAME> <NEW_NAME> — assign a human-friendly alias or name to an existing session.
• /session delete <SESSION_ID|NAME> — delete an existing session if no longer needed.
• Optionally mirror all of the above with CLI subcommands (e.g., codex session list, codex session rename …) for non-TUI workflows.

---

Why is this important?

• When working on multiple features/tasks/projects simultaneously, it greatly improves productivity to be able to keep multiple sessions (contexts) running side-by-side, and switch among them easily — just like tmux windows/sessions.
• While Codex CLI already supports codex resume to pick up an old session, the workflow lacks human-friendly names/aliases, intuitive listing of sessions, and switching inside the interactive mode without dropping to shell.
• This will enable better project hygiene: easier to identify which session is for which task, organize by project, reduce cognitive overload when managing many sessions.
• A more robust session management system aligns with user expectations from other CLI agents (for example, Claude Code)

Existing related issues/discussions

• Discussion #341: “Feature: Multi-Session Management for Codex CLI” — users requested save, name, list, switch between multiple sessions. :contentReference[oaicite:6]{index=6}
• Issue #2080: “Add Chat Session Management: chat list, chat resume or --restore-session” — highlights lack of built-in commands to list/resume sessions. :contentReference[oaicite:7]{index=7}
• Issue #146: “feat: session persistence” — earlier request to continue a previously saved session/thread via /session. :contentReference[oaicite:8]{index=8}

While these cover parts of the session-management spectrum, none explicitly covers the full interactive in-TUI slash command workflow (/session) plus rename/delete/list/switch exactly as proposed here.

Are you interested in implementing this feature?

Yes — I’m willing and ready to contribute the implementation (forking the repo, writing tests, updating docs, submitting a PR) if the maintainers agree that this feature aligns with the roadmap and is open for review.

Thank you for considering this enhancement. I believe it will significantly improve the workflow for users managing multiple tasks/projects with Codex CLI.
