Claude Code 2.1.236 adds ANTHROPIC_DEFAULT_MODEL to pin your model
The env var sets your model once for new sessions; the same release makes /goal check in on its own, tightens a macOS sandbox rule, and unclips /model.

Pin your model with one env var
Set ANTHROPIC_DEFAULT_MODEL and every new session boots on that model — no re-picking after each launch or when a session resets. Handy for defaulting to a cheaper model and reaching for Opus only when you actually need it.
/goal sessions stop hanging forever
Idle /goal sessions now check in on their own after 30 minutes instead of waiting indefinitely, so a long-running goal keeps moving while you're away from the keyboard.
The /model picker finally scrolls
When your model list ran taller than the terminal, the picker got cut off; it's now scrollable so every model is reachable. A small daily annoyance, gone.
A macOS sandbox read-deny hole closed
Wildcard read-deny rules weren't matching correctly on macOS, so a path you meant to block could still be read. 2.1.236 fixes the matching — your sandbox denylist now behaves as written.
Ping another session the moment it idles
SendMessage gains notify_when_idle on macOS and Linux: fire a message at another Claude session and get pinged the moment it goes quiet — useful when you're juggling several sessions at once.
