Anthropic's Claude Code v2.1.236 release introduces an `ANTHROPIC_DEFAULT_MODEL` environment variable, a cross-session `notify_when_idle` feature, and several sandbox, UI, and auto mode improvements and fixes.
READY TO POST:
claude code just dropped v2.1.236! looks like they added a default model env var and a neat cross-session idle notification. could be handy for dev workflows.
anthropic's claude code got an update with better sandbox rules on macos, a bunch of bug fixes, and some auto mode tweaks. always good to see those quality of life improvements.

## What's changed
- Added `ANTHROPIC_DEFAULT_MODEL` environment variable: sets the model new sessions start on, while a `/model` pick still overrides it and persists across restarts (unlike `ANTHROPIC_MODEL`)
- Added `notify_when_idle` to cross-session `SendMessage`: ask another Claude Code session on this machine to send one notice when it next goes idle — opt-in, one-shot, no polling (macOS and Linux)
- Sandbox: on macOS, wildcard read-deny rules (e.g. `**/.env`) now take precedence inside allowed read regions, cover matched directories' contents, and can't be bypassed by renaming the denied file
- Fixed clipboard copy, background housekeeping, background sessions, and local MCP logs breaking after the directory a session had switched into was removed (since 2.1.229)
- Fixed the fullscreen renderer failing permanently after a single failed start: it now falls back to the classic renderer instead of exiting on every subsequent launch
- Fixed the `/model` picker rendering taller than the terminal: it now shows only as many models as fit the window, with the rest reachable by scrolling
- Fixed `SendMessage` calls being rejected when a malformed closing tag left the message text inside the summary field
- Fixed unhandled promise rejections when a subprocess fails to start, for example `powershell.exe` on WSL with Windows interop disabled (regression in 2.1.234)
- Fixed fullscreen mode sometimes not showing a newly sent message until the next update after the terminal was resized
- Fixed a blank band that could remain above the prompt after clearing a multi-line prompt, and panes not repainting after resizing the terminal away and back, in fullscreen mode
- Fixed the managed-settings app
