## 精选理由

子代理现在可以递归生成子代理（最多 5 层），这个特性让复杂的多 agent 编排成为可能，但总体还是以 bug 修复为主，Bedrock 的区域读取也更顺手了，Claude Code 用户直接升级即可。

## AI 摘要

子智能体现可创建自己的子智能体，最多嵌套5层。Amazon Bedrock 在未设置 AWS_REGION 时从 ~/.aws/config 读取区域。插件市场新增搜索栏。修复了使用1M上下文且无使用额度的会话永久卡住的问题，现会自动压缩回标准上下文限制。修复了多个图片导致重复报错等问题。改进了长对话性能，减少冗余消息归一化和不必要的UI重绘，降低空闲CPU占用。Claude in Chrome 工具加载改为单次批量调用。/code-review 在未登录时保留 ultra 选项并提示需要 claude.ai 账户。

What's changed

Sub-agents can now spawn their own sub-agents (up to 5 levels deep)

Amazon Bedrock now reads the AWS region from ~/.aws config files when AWS_REGION isn't set, matching AWS SDK precedence; /status shows where the region came from

Added a search bar when browsing a marketplace's plugins in /plugin

Added model attribute to the claude_code.lines_of_code.count OTEL metric

Fixed sessions using 1M context without usage credits getting permanently stuck — the session now automatically compacts back under the standard context limit

Fixed a repeating "an image in the conversation could not be processed and was removed" error when the conversation contained multiple images

Fixed the agents view keeping a session under Working with a busy spinner for up to 30 seconds after the worker replied

Fixed background agents potentially reading another directory's project settings (.mcp.json approvals, trust) when dispatched onto a pre-warmed worker

Fixed background-session attach failing with EAUTH for sessions started on an older version after the daemon auto-updated

Fixed a background sub-agent staying stuck as "active" in the agent panel after a nested agent it spawned was stopped

Fixed /model suggestions in the claude agents dispatch input rendering with a misleading slash prefix and showing models disabled for your org

Fixed availableModels restrictions not being applied to subagent model overrides, the agent dispatch model picker, and the advisor model

Fixed availableModels allowlists hiding the /model picker's Opus and Sonnet 1M rows when entries use version-specific IDs like claude-opus-4-8

Fixed the /model picker on Bedrock offering models the provider doesn't serve — selecting one silently switched the session model and lit the selection marker on multiple rows

Fixed model IDs getting a doubled 1M-context suffix (e.g. [1M][1m]) when ANTHROPIC_DEFAULT_OPUS_MODEL already includes one

Fixed opusplan model setting not shipping with 1M context in plan mode for entitled users; the opusplan[1m] workaround now also correctly switches to Opus in plan mode

Fixed WebFetch(domain:*.example.com) wildcard domain rules never matching subdomains in allow, deny, and ask position, and file permission rules with mid-pattern wildcards (e.g. Read(secrets-*/config.json)) being rejected at startup

Fixed up-arrow prompt history showing the main agent's prompts while a subagent's chat tab is open

Fixed memory recall not finding mounted team memory stores (CLAUDE_MEMORY_STORES) in remote sessions

Fixed workflow validation rejecting scripts whose prompt strings or comments merely mention Date.now()/Math.random()

Disable mouse tracking on Windows consoles that don't fully support it

Fixed the /plugin marketplace list losing its cursor after backing out of a long plugin list, and Esc from the plugin browser returning to the wrong tab

Improved performance in long conversations by removing redundant message normalization and avoiding full message-history transforms when streaming tool-use state is unchanged

Reduced idle CPU usage: /goal status chip no longer re-renders the terminal at 5 Hz while idle, and fewer UI re-renders while subagents run in parallel

Improved Claude in Chrome tool loading: browser tools now load in a single batched call instead of one per tool

Improved the non-interactive Usage Policy refusal message to suggest starting a new session or changing your model

/code-review now keeps the ultra option visible when you're not signed in to claude.ai, with an explanation that the cloud review requires a claude.ai account

Shortened the Remote Control footer indicator to "/rc active" and hid it on narrow terminals

Stopped promoting /loop in remote sessions, where pending loops don't keep the container alive

[VSCode] Fixed PowerShell tool calls rendering as raw JSON instead of a proper command display and permission dialog, and stripped ANSI escape codes from displayed shell output
