SessionEnd hook doesn't fire on /exit command

Description

The SessionEnd hook fires when exiting via ctrl-d but not when using the /exit slash command.

Steps to Reproduce

1. Configure a SessionEnd hook in ~/.claude/settings.json:

{
  "hooks": {
    "SessionEnd": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "/bin/bash ~/.claude/session-end-hook.sh"
          }
        ]
      }
    ]
  }
}

1. Create a hook script that writes to /dev/tty:

#!/bin/bash
input=$(cat)
session_id=$(echo "$input" | jq -r '.session_id // empty')
echo "To resume: claude --resume $session_id" > /dev/tty

1. Start a claude session and exit with /exit - hook does NOT fire
2. Start a claude session and exit with ctrl-d - hook DOES fire

Expected Behavior

SessionEnd hook should fire for both /exit and ctrl-d exits.

Documentation Note

The hooks documentation lists these SessionEnd reasons:

• clear
• logout
• prompt_input_exit
• other

But the example JSON shows "reason": "exit" which isn't in this list. It's unclear whether /exit should use "exit", "other", or a new reason.

Environment

• macOS
• Claude Code CLI
