Claude Code v2.1.209: fix for blocked dialogs in background agent sessions

2026-07-17 ยท source:

Claude Code 2.1.209 reverts an overly broad guard that had been blocking /model and other dialogs inside claude agents background sessions.

What it is

A patch release of the Claude Code CLI, version 2.1.209.

What it does

It reverts a prior change that incorrectly blocked slash-command dialogs like /model from opening while running claude agents in background sessions.

Why it matters

Anyone managing multiple background agent sessions needs slash commands to keep working reliably instead of silently failing to open.

How to use it

Update Claude Code with the standard updater or package manager to pick up 2.1.209 and later.
