Claude Code 2.1.221 → 2.1.222
Two stable releases in one day. 2.1.221 adds VS Code Focus view (tool noise collapsed behind a per-turn summary), sandbox credential mode: "mask" on Linux/WSL, and closes Bash/PowerShell permission bypasses.2 2.1.222 closes the one that matters for multi-agent work: worktree-isolated sessions and their subagents could still run destructive git against the main checkout — isolation now covers file edits and Bash in every session type.3
Relevant to: anyone running Claude Code with worktrees, subagents, or auto-mode on a shared repo
What the verdict meansAvailable, works, worth your time today.
Deeper — other fixes worth the upgrade
- PreToolUse auto-allow hooks no longer bypass tool restrictions inside background agent tasks (summaries, compaction, renames).
- SendMessage between agent sessions is now classified before dispatch in auto mode.
- Remote Control can no longer be turned on from repo-local settings — only user-scope
/configenables it; local settings can still turn it off. - Ultraplan was removed in 2.1.222. If a workflow depended on it, it is gone.
