## AI 摘要

Claude Code v2.1.273 新增 x-claude-code-request-class 等 5 个 LLM 网关请求头，需用 CLAUDE_CODE_GATEWAY_HINT_HEADERS=1 开启，并支持从 Claude app 分叉 --remote-control 会话在本地后台运行。

## 正文

What's changed

Added x-claude-code-request-class, x-claude-code-agent-type, x-claude-code-prev-tool-durations, x-claude-code-compaction and x-claude-code-context-compacted request headers for LLM gateways; opt in with CLAUDE_CODE_GATEWAY_HINT_HEADERS=1

Added a notification when an MCP server disconnects mid-session and automatic reconnection gives up, pointing at /mcp

Added forking a session started with claude --remote-control or /remote-control from the Claude app; the fork runs as a background session on your computer

Fixed Bash commands the permission checker cannot fully analyze skipping the prompt under permissions.blockReadsOutsideWorkingDirectories, and a subshell hiding a dangerous rm in bypass mode

Fixed skills synced from claude.ai staying available after your organization turns Skills off; they now move to the recoverable trash

Fixed allowManagedMcpServersOnly, deniedMcpServers and disableClaudeAiConnectors set via MDM or managed-settings.json being ignored when server-managed settings are also present

Fixed 401/403 errors on Bedrock, Vertex and Foundry, and Claude apps gateway 403s, telling you to run /login; the message now names the credential to refresh or points to your gateway administrator

Fixed /login, /upgrade, and /extra-usage discarding earlier thinking from the conversation, which forced a full prompt-cache rewrite on the next request

Fixed auto mode stopping for approval when the Artifact tool uploads a file you attached to the chat in a cloud or Remote Control session

Fixed a long-running session recreating a stub .git/info/exclude after the repository's .git directory was removed or moved away

Fixed the main prompt dropping a ! typed at the start while already in shell mode, so negated commands like ! grep … can be typed

Fixed Read on macOS refusing a dragged-in screenshot, or any file the system reports under a second path, with "symlink resolution changed after permission was checked"

Fixed permissions.blockReadsOutsideWorkingDirectories: a memory directory chosen by a repository's settings is no longer loaded into the prompt, recalled, indexed, or used by memory extraction

Fixed sub-agents and background agents being reported as failed, with their result never delivered, when the final streamed reply omitted token usage or carried no model id

Fixed the context meter and auto-compact counting advisor-tool turns at roughly twice their real context size, which made auto-compact fire at about half the real window

Fixed /tui refusing to restart because of an agent-team teammate that had already finished its work and was no longer shown in the agents panel

Fixed saved scheduled tasks running in the wrong session after .claude/scheduled_tasks.json was copied into another folder, such as a new worktree

Fixed SDK and --output-format stream-json output dropping a subagent's remaining messages and final report after it is moved to the background mid-run (e.g. by CLAUDE_AUTO_BACKGROUND_TASKS)

Fixed /install-github-app reporting a SAML single sign-on block as "admin permissions required"

Fixed Remote Control clients attached to a Claude Desktop, VS Code or JetBrains session being refused when they ask for the session's context window usage

Fixed the spinner showing a doubled ellipsis ("……") on compaction status lines such as "Running PreCompact hooks…"

Fixed a false-positive spinner tip suggesting the frontend-design plugin after reading or publishing Artifacts

Reverted a 2.1.268 change that checked Read and Edit deny rules on Bash lines the permission checker can't analyze (eval, env -C); commands like time -p make build prompt again instead of being denied

Improved responsiveness in long sessions: hook progress and sub-agent activity no longer re-process the whole conversation on every update

Improved the Artifact tool's error when a publish includes a file type artifacts don't serve: Claude is told which types are served and what to do instead, and the terminal shows one plain line

Improved the Artifact tool's page read to state the capabilities and database rules the artifact service holds for the page, for anyone who can publish to it

Improved artifact database writes: an update can now remove a single field instead of rewriting the whole document

Improved artifact publishing: a publish whose connection drops after reaching claude.ai is now re-sent safely instead of failing or creating a duplicate version

Improved the cloud-session GitHub error for an IP allow list, a suspended app installation or SAML single sign-on to show the cause instead of a generic install hint

Improved /autofix-pr: when gh pr view fails it now shows gh's own error (sign-in, SAML, rate limit) instead of a generic exit-code line

Improved /autofix-pr to say why GitHub webhook delivery couldn't be set up for the PR (for example, no linked GitHub account) instead of a generic warning

Improved /web-setup errors: a refused GitHub token now lists the likely reasons and the fix, and a connection failure names a configured proxy or TLS certificate problem

Improved the in-session SSL certificate and proxy connection errors to name the error code and what to fix, such as NODE_EXTRA_CA_CERTS for an untrusted corporate CA

Improved the error when a cloud session can't be created because your Claude login expired or was revoked: it now tells you to run /login

Improved the error shown when an MCP server's sign-in expires mid-session to say how to re-authenticate (/mcp)

Changed auto mode on Bedrock, Vertex and Foundry to use the local classifier by default for now; set CLAUDE_CODE_AUTO_MODE_SERVER=1 to use the platform's server-side classifier

Changed OTEL_LOG_TOOL_DETAILS=1 to also include real agent, skill, plugin and MCP server names on cost and token metrics

Changed sign-in with a Claude account to also request access to your claude.ai plugins

Changed /bug and /feedback reports to include only model-behavior params (model, system prompt, tools) from the last API request, omitting request metadata and CLAUDE_CODE_EXTRA_BODY fields

[VSCode] Fixed "Report a problem" still appearing, and /bug / /feedback opening a report form, for organizations that have product feedback disabled

[VSCode] Fixed a red "Claude Code process exited with code 4294967295" banner appearing after completed turns on Windows

Windows: Improved the network-path permission check for UNC paths when a mapped network drive was added with --add-dir

[Claude Code on the web] Fixed routines losing access to an organization connector, and still calling the old one, after an admin removed and re-added that connector

[Claude Code on the web] Fixed creating a self-hosted environment from organization settings occasionally failing with a server error and leaving a half-created environment behind

[Claude Code on the web] Changed the admin "Share cloud sessions" setting to live under Data and privacy instead of the Claude Code page, where Data and privacy admins can also manage it

[Claude Code on the web] Added a "Discard unsaved changes?" confirmation before the New routine page or the Edit routine dialog throws away a routine name, prompt or edit you typed

[Claude Code on the web] Removed the full-page desktop-app download screen that new users without a cloud environment saw on Mac and Windows; they now go straight to setup

[Claude Code on the web] Improved the routine detail page: menu and rename in the breadcrumb, the on/off switch and Run now at the top, and run history beside the routine's settings

[Claude Tag] Fixed Claude going silent minutes after reinstalling the app when an Enterprise Grid was disconnected but one of its workspaces stayed connected

[Claude Tag] Fixed scheduled tasks set up in an organization-shared private Slack channel silently never posting; they now keep running in the thread they were created in

[Claude Tag] Fixed replying in an older Slack thread while Claude is mid-task sometimes restarting it from scratch and losing work it had not pushed yet

[Claude Tag] Fixed Claude occasionally dropping a message with an incorrect "couldn't find a Claude Code environment" notice right after your account token refreshed

[Claude Tag] Fixed AWS connections refusing region-less endpoints such as Budgets, Savings Plans, WAF Classic and Import/Export; Global Accelerator requests now sign correctly

[Claude Tag] Improved AWS connection failures: when a request can't be signed, such as a hostname with no region, Claude is told why and how to fix it instead of a bare error

[Claude Tag] Fixed OAuth client-credentials and JWT-bearer connections failing with providers that return a lowercase token type; requests now send the standard Bearer scheme

[Claude Tag] Fixed adding a channel manager being refused on Enterprise Grid shared channels, on channels where Claude hasn't been used yet, and on legacy private channels

[Claude Tag] Changed Claude to start watching related public channels on its own, such as an incident channel a conversation depends on, instead of only when asked

[Claude Tag] Fixed the admin Memory page not listing Slack channels Claude set up on its own even when they had saved memory; admins can now open, edit and delete that memory

[Code Review] Fixed merging the base branch into a PR whose earlier review listed "Additional findings" triggering a full re-review; these pushes now get the lighter follow-up review

[Code Review] Fixed a whole REVIEW.md being ignored because of an @-mention, a code span wrapped across lines, or a backticked HTML tag; only lines linking to changed files are withheld

[Code Review] Improved suggested fixes to say what the fix must keep working when other code depends on the behavior being changed

[Code Review] Improved review comments that point to a second affected location to state that location's issue in a full sentence instead of a cut-off stub

[Code Review] Fixed /ultrareview --post so a retry after a GitHub error posts the findings comment exactly once instead of never or twice; the comment now names the reviewed commit

[Code Review] Fixed empty or content-identical pushes being re-reviewed on GitHub repositories whose owner or name contains a capital letter; these pushes are now skipped
