## AI 摘要

Claude Code v2.1.222 发布，修复了工作树隔离会话及其子代理可对主检出运行破坏性 git 命令的问题，隔离现适用于所有会话类型的文件编辑和 Bash。

## 正文

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
