Problem Statement

Feature Request

Currently, Claude Code has no built-in way to delete individual conversation sessions from the CLI. The only options are to resume or list sessions via claude
--resume, but there is no delete functionality.

Proposed Solution

Add a CLI flag or command to delete a specific session or all sessions, for example:

claude --delete <session-id>
claude --delete --all

Alternative Solutions

Current Workaround

Manually locating and deleting session files from ~/.claude/projects/, which is error-prone and not user-friendly.

Priority

Medium - Would be very helpful
