Problem Statement

Currently, UX lacks a feature to delete all existing Claude Code sessions and to delete a session by name. This feature is vitally important as I want to have a full control of all of my conversations in different sessions and to have a tool to efficiently manage the memory those sessions fill.

Proposed Solution

When I am inside Claude Code session, I want to run /delete-sessions to delete all current sessions to free the memory. If I want to delete a particular session, I would run /delete-sessions and backspace to see available session to delete. Then, I will go ahead and choose a particular one for deletion.
