Unclear What triggers the clearing of these variables, and what sets them in the first place, is not settled.

What

Claude Code now holds a safe value for three environment variables (settings you pass to a program through the shell) that control Claude in Chrome:

It can check whether each one is still at its safe value and can remove all three from its own environment. These three, along with CLAUDE_AFK_TIMEOUT_MS, CLAUDE_AFK_COUNTDOWN_MS and CLAUDE_CODE_USER_DIALOG_TIMEOUT_MS, were added to a list of variables Claude Code handles specially.

A new variable, CLAUDE_CODE_REMOTE_TOOLS_HOST_ALLOWS_UNATTENDED, is also on that list and is removed from the environment of child processes, the programs Claude Code starts. CLAUDE_CODE_REMOTE_HERMETIC_MODE now only counts when CLAUDE_CODE_REMOTE is also set.

Before a session is allowed to run tools on your computer, Claude Code now keeps a copy of the folder's settings. If it cannot, it stops with a message asking you to check disk space and ~/.claude/state.

Why

This looks like a lock-down of the Chrome and unattended permission settings, so that programs Claude Code starts cannot pick up relaxed values from the environment.
