[FEATURE] Claude Code Sessions Count

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 there's no way to see which Claude Code sessions are actively running in real-time. /resume shows historical sessions but doesn't distinguish between sessions that are currently executing vs. idle/closed. If I have multiple terminal windows open, I can't tell from within Claude Code which other sessions are still active.

Proposed Solution

Describe the solution you'd like

A command (e.g. /sessions or claude --list-active) that shows all currently running Claude Code sessions in real-time, including:

Session name / initial prompt
Status (running / idle / waiting for input)
Which directory / project each session is in
How long it's been running
Describe alternatives you've considered

Alternative Solutions

Or:
A small number count in the Claude Code CLI

Additional Context

This would be especially useful for users who run multiple sessions in parallel (e.g. with --worktree) and want a quick overview of what's going on.
