Feature request: /name command to rename active session

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Currently, sessions can only be named at startup using claude -n "name".
You often realize during a session that you want to name it.
So if you forget to name a session, or want to rename it based on what you ended up working on, there's no way to do so.

Proposed Solution

Add a /name slash command:

/name "finance calculator refactor"

Alternative Solutions

• Restarting with -n loses context
• Comments in chat don't appear in /resume

Priority

Medium - Would be very helpful

Feature Category

Interactive mode (TUI)

Use Case Example

1. Forgot to name at startup
2. Scope changed during session
3. Want descriptive name after long session
