GitHub: v2.1.222

What's changed

• Fixed worktree-isolated sessions and their subagents being able to run destructive git commands against the main checkout; isolation now applies to file edits and Bash in every session type
• Fixed PreToolUse auto-allow hooks bypassing tool restrictions in background agent tasks (summaries, compaction, renames)
• Fixed /usage-credits on Team and Enterprise showing "you've already sent a usage credit request" for members whose earlier request was dismissed, blocking them from sending a new one
• Fixed the startup connectivity check hanging and then failing behind an HTTPS proxy; it now uses the same proxy-aware transport as API requests and times out with a clear message
• Fixed "Connection closed mid-response" errors being reported on responses that had actually completed
• Fixed /usage overattributing usage to MCP servers: a server's share now reflects only the requests that actually consumed its tool results, instead of every turn after any call to it
• Fixed sessions not linking to pull requests created after the branch was pushed, including through the GitHub REST API
• Fixed org-restricted model: opus-style subagent and teammate family aliases dropping to the parent model instead of stepping down to the newest org-allowed model in the family
• Fixed stream idle timeout firing on custom ANTHROPIC_BASE_URL gateways despite server keep-alive pings arriving on the wire
• Fixed claude.ai connectors being falsely marked as needing authorization when the session token is invalid — they now show a /login hint instead
• Fixed tool errors not being displayed for tools no longer available locally, for example after an MCP server is removed
• Fixed SendMessage rejecting a long summary — it now truncates instead, so sends no longer fail on a character limit
• Fixed the spinner's effort label in a subagent's transcript view showing the session's effort level instead of the subagent's own effort: setting
• Fixed rare crashes when a file watcher hit a filesystem error or during file-watcher teardown
• Fixed screen readers re-reading the whole input line on every backspace in --ax-screen-reader mode — end-of-line deletions now echo just the deleted characters
• Fixed host model-selection keys not taking precedence over a stale on-disk managed-settings.json when CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST is set
• Improved auto mode safety: messages sent to other agent sessions via SendMessage are now evaluated by the permission classifier before dispatch
• Improved the refusal when Claude tries to invoke a skill with disable-model-invocation: Claude is now told to ask you to run the skill instead of replicating its workflow
• Improved the /diff view, the Remote Control workspace diff, and file-edit diffs in Claude Code on the web sessions to use raw git blob content, ignoring workspace-configured diff drivers and textconv
• Changed Remote Control auto-start so repo-local settings (.claude/settings.json or .claude/settings.local.json) can no longer turn it on (they can still turn it off); enable it at user scope via /config
• Removed ultraplan feature
