[FEATURE] Auto-rename terminal tab title based on conversation topic after /clear

Problem Statement

After running /clear, the terminal tab title remains set to whatever the previous conversation was about. There's no way to automatically reset it or have it update based on the new conversation's topic.

Proposed Solution

A new hook event (e.g., AfterFirstResponse) that fires after Claude's first reply in a session
Expose a conversation summary or topic string in the hook's input JSON

Alternative Solutions

Alternatively, a built-in autoTitle setting that handles this without requiring hooks

Priority

Medium - Would be very helpful

Feature Category

CLI commands and flags

Use Case Example

When running multiple Claude Code sessions in tabs, they all become indistinguishable after /clear. Dynamic titles would make tab management significantly easier
