Changes on 2026-02-20

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** 5 pages of diffs (`intro.md`, `get-started.md`, `build-with-claude/overview.md`, `agents-and-tools/tool-use/programmatic-tool-calling.md`, `CHANGELOG.md.md`). * **Output Format:** Markdown, concise, insightful. * **Language:** Chinese. * **Structure:** 1. Overall Summary. 2. Key Themes. 3. Impact Level. 4. Action Items. 2. **Analyze the Diffs:** * **intro.md:** * *Change:* "Get started" section restructured from a generic card list to a specific "Recommended path for new developers" with 4 clear steps (Make API call -> Understand Messages API -> Choose model -> Explore features). * *Change:* Minor text tweaks (e.g., "best-in-class" -> "provides", "enjoy easier" -> "prototype and test"). * *Insight:* Improves onboarding flow for new users. * **get-started.md:** * *Change:* "Next steps" section restructured. First highlights "Working with the Messages API" as the critical next step after the first API call. Then lists "Further exploration" (Models, Features, SDKs). * *Change:* Text refinements ("Get your API key at" -> "from", "Explore" -> "Browse"). * *Insight:* Aligns with `intro.md` changes, guiding learning path more effectively. * **build-with-claude/overview.md:** * *Change:* Added a summary section at the top explaining the 5 areas of the API surface (Model capabilities, Tools, Tool infrastructure, Context management, Files and assets). * *Change:* Grammar fix: "Batch API calls costs 50%" -> "cost 50%". * *Change:* Header title fix: "Files & assets" -> "Files and assets". * *Insight:* Better organization of high-level concepts and grammar fixes. * **agents-and-tools/tool-use/programmatic-tool-calling.md:** * *Change:* Updated `code_execution` tool version string from `20250825` to `20260120`. This applies to Opus 4.6, Sonnet 4.6, Sonnet 4.5, Opus 4.5. * *Change:* Removed "Web search" and "Web fetch" from the list of tools that cannot currently be called programmatically (implying they might now support it or it was removed for other reasons? Actually, looking at the context, it removes them from the exclusion list, suggesting they *might* be supported or the section was simplified. However, the diff specifically deletes those two lines). * *Insight:* Critical update for tool definition strings. Likely relates to an update in the code execution capability or date-based versioning. * **CHANGELOG.md.md:** * *Version 2.1.50*: Major focus on **memory leaks** (multiple fixes for long sessions, LSP diagnostics, TaskOutput, CircularBuffer, ChildProcess). * *Features:* `startupTimeout` for LSP, Worktree hooks, `isolation: worktree` for agents, `claude agents` command. * *Fixes:* Linux glibc compatibility, session visibility with symlinks, SSH disconnect data loss, MCP tool discovery. * *Performance:* Better memory usage, startup performance for headless mode. * *Context:* Opus 4.6 (fast mode) now includes full 1M context. * *Insight:* Heavy focus on stability and performance, specifically memory management and CLI/Agent tooling features. 3. **Synthesize the Findings:** * *Theme 1: Improved Onboarding & UX.* The docs are getting a facelift to guide new users better (intro, get-started). * *Theme 2: API Versioning & Tooling Updates.* `code_execution` version string changed (from Aug 2025 to Jan 2026 - wait, the dates are in the future? That's standard for pre-planned versions or just string identifiers. `20260120` implies a version from Jan 20, 2026). *Correction*: The current date is likely later, or these are placeholders. Regardless, the version string *changed*, which is the important part. * *Theme 3: Stability & Performance (CLI).* The changelog is dominated by memory leak fixes and performance improvements for long-running sessions. * *Theme 4: Agent/CLI Enhancements.* Worktree support, better hooks, and LSP config. 4. **Draft the Content (in Chinese):** * **Summary:** 此次更新集中优化了文档结构以改善新用户体验，并修复了多项关键的性能和稳定性问题（特别是内存泄漏）。同时更新了代码执行工具的版本标识符。 * **Themes:** * **文档重构:** 首页和快速入门页面的引导路径更加清晰，强调“首次调用” -> “消息 API” -> “模型选择”的学习路径。 * **稳定性与性能:** Changelog 显示大量关于内存泄漏的修复（LSP、Agent Teams、长会话等），以及提升 Linux 兼容性和 SSH 稳定性。 * **工具与 CLI 增强:** 新增 Agent 工作树支持、LSP 配置选项，并优化了 CLI 的启动性能和内存使用。 * **API 版本更新:** `code_execution` 工具版本从 `20250825` 升级至 `20260120`。 * **Impact:** **High** (对于 CLI 用户和长期运行 Agent 的开发者)。**Medium** (对于仅阅读文档的用户)。**Low/Breaking** (需要更新硬编码的工具版本字符串)。 * **Action Items:** * 如果使用了 `code_execution` 工具，请更新代码中的版本字符串。 * 升级 CLI/编辑器扩展以解决长期会话中的内存泄漏问题。 * 关注新的 `isolation: worktree` 和 Worktree Hooks 功能以改进 Agent 隔离。 5. **Refine and Polish (Markdown formatting):** * *Summary:* 简明扼要，覆盖文档变更和 Changelog 的核心。 * *Themes:* 提取关键词（UX, Memory, Tools）。 * *Impact:* 判断为 High，因为 Changelog 显示很多严重的内存泄漏修复，这直接影响生产环境稳定性。Breaking change 主要涉及硬编码字符串。 * *Action:* 具体的代码更新建议。 6. **Final Review against constraints:** * Concise? Yes. * Insightful? Yes, connects the dots between doc changes and changelog fixes. * Chinese? Yes. * Focus on developers? Yes. *(Self-Correction during drafting)*: The date in the tool version string (`20260120`) is in the future relative to typical release cycles, but I should treat it as a literal string update requirement. The prompt asks for analysis, not speculation on dates. *Changelog Details:* The changelog is specifically for the CLI/IDE extension (likely `claude-code` or similar tooling given mentions of VSCode, LSP, Worktrees), not the Anthropic API itself, though the intro docs cover the API. I should distinguish between "Developer Tools" (the CLI mentioned in Changelog) and "Claude API" (docs). The prompt says "Total changed pages", implying these docs are for the *Developer Tools* suite provided by Anthropic, possibly the Claude desktop app/CLI wrapper context, OR the Changelog is for the Claude Code CLI. Wait, `intro.md` talks about `claude.ai` and `Anthropic API`. `CHANGELOG.md` talks about `CLAUDE_CODE_SIMPLE`, `claude agents` CLI command. This suggests the documentation covers the **Claude Code CLI/Agent** tooling, not just the raw API. *Actually*, looking at `intro.md`, it mentions "Make your first API call to Claude". This is the *general* Anthropic docs. But the Changelog refers to `claude agents` command and VSCode. This implies this repository/project contains both general API docs AND specific tooling (CLI) docs. Or perhaps the Changelog is just included in this batch. *Decision:* I will analyze the batch as a whole. The Changelog significantly impacts developers using the CLI/Agent features. The Doc changes impact API users. I will highlight the Changelog's focus on the CLI/Agent tooling stability. 7. **Final Output Generation.**

1. **Understand the Goal:** The user wants a concise, insightful analysis of documentation changes (Markdown format, Chinese response) from two specific pages related to "agents-and-tools". I need to focus on what matters to developers. 2. **Analyze the Input Data:** * **Page 1:** `agents-and-tools/tool-use/bash-tool.md` * *Change:* Added a `<Note>` block. * *Content:* Warns about using "code execution tool" and "bash tool" together. Highlights that they are two separate environments (local bash vs. Anthropic sandbox) with no shared state. Points to a new section in the code execution tool doc for guidance. * **Page 2:** `agents-and-tools/tool-use/code-execution-tool.md` * *Change:* Added a new section "Using code execution with other execution tools". * *Content:* Explains the concept of a "multi-computer environment". Warns that Claude might confuse environments if they aren't distinguished. Provides a specific prompt template/instruction block to add to the system prompt to mitigate this. Mentions web search/fetch enabling code execution automatically, creating potential conflicts with existing shell tools. 3. **Synthesize the Analysis:** * **Overall Summary:** The changes address potential confusion and state management issues when using multiple execution environments (specifically the Code Execution tool alongside local tools like Bash) within the same agent workflow. * **Key Themes:** * *Multi-environment isolation:* Clarifying that Anthropic's sandbox and the user's local environment (bash) are distinct. * *State management:* Emphasizing that state (variables, files) does not persist across these separate environments. * *Prompt Engineering Guidance:* Providing concrete system prompt instructions to help Claude distinguish between tools. * **Impact Level:** Medium. It's not a breaking API change, but it is a significant usability improvement for developers building complex agents. Without this fix, agents might fail silently or behave unexpectedly by trying to access local files in the cloud sandbox or vice versa. * **Action Items:** * Review system prompts if using both code execution and bash tools. * Implement the suggested instructions to clarify environment distinctions. * Be aware that tools like Web Search implicitly enable code execution, potentially creating a dual-environment setup even if not explicitly requested. 4. **Drafting the Response (in Chinese):** * *Summary:* 文档更新解决了在同时使用 Anthropic 沙箱代码执行工具和本地执行工具（如 Bash）时产生的环境混淆和状态管理问题。 * *Key Themes:* * 多环境隔离：明确区分 Anthropic 沙箱环境与用户本地环境。 * 状态非共享：强调变量和文件在不同执行环境之间不会自动持久化。 * 提示词工程：提供了具体的系统指令模板，帮助 Claude 正确区分不同的执行上下文。 * *Impact Level:* Medium. This is a critical fix for agent reliability in complex setups, but existing code doesn't break; it just might act weirdly without these prompts. * *Action Items:* * 如果你的应用同时启用了代码执行工具和 Bash 工具，请更新系统提示词。 * 将文档中提供的关于环境区分的指令块加入到系统提示词中。 * 注意 Web Search/Web Fetch 等工具会自动启用代码执行，可能意外引入双环境问题。 5. **Review against constraints:** * Concise? Yes. * Insightful? Yes, identifies the core problem (state confusion). * Markdown format? Yes. * Chinese response? Yes. * Developer focus? Yes. 6. **Final Polish:** Ensure the tone is professional ("World-class programmer"). * *Drafting the final output...* (Self-correction: Make sure to mention the specific system prompt snippet as it's a high-value takeaway). 7. **Final Output Generation** (matches the provided good response).

1. **Analyze the Request**: * **Role**: World-class programmer analyzing documentation changes. * **Task**: Analyze a single batch of documentation changes (2 pages). * **Output Format**: Markdown, concise, insightful, developer-focused, Chinese. * **Structure**: 1. Overall Summary (1-2 sentences). 2. Key Themes (bullets). 3. Impact Level (Low/Medium/High/Breaking) with reasoning. 4. Action Items (max 5). 2. **Analyze the Diffs**: * **Page 1: `desktop.md` (+161 / -52)**: Significant expansion and refinement. * *Intro Section*: Changed from a single paragraph description to a bulleted list highlighting specific features (Visual diff, Live app preview, GitHub PR monitoring, Git worktree isolation, Connectors, environments). * *Terminology Updates*: * "Git isolation" -> "Git worktree isolation" (more specific technical term). * "cloud environment" -> "Remote" (simpler UI term). * "Model" link updated: `/en/overview#models` -> `/en/model-config#available-models` (architectural change in docs). * *Permission Modes*: Table updated. * "Ask" -> "Ask permissions" * "Code" -> "Auto accept edits" * "Plan" -> "Plan mode" * "Act" -> "Bypass permissions" * "Best practice" tip text updated to reflect new names. * *Overall Implication*: The documentation is being polished for clarity and precision. The move to more descriptive mode names (e.g., "Code" -> "Auto accept edits") reduces ambiguity. Emphasis on new features like "Live app preview" and "PR monitoring" suggests the Desktop app has gained significant features recently. * **Page 2: `overview.md` (+5 / -5)**: Minor syntax and link fixes. * *Code Blocks*: Added duplicate `theme={null}` attributes in Markdown code blocks (e.g., ` ```bash theme={null} theme={null} `). This looks like a minor formatting bug or specific renderer configuration change in the build system, not a content change. * *Link Update*: Link to "desktop" page changed from `/en/desktop#get-started` to `/en/desktop-quickstart`. This aligns with the tip in `desktop.md` pointing to `/en/desktop-quickstart`. It suggests a restructuring of the getting started flow (likely split into a "quickstart" vs "overview"). 3. **Synthesize Key Themes**: * **Feature Clarity & Marketing**: Highlighting specific enterprise/dev-centric features (PR monitoring, Git worktree) in Desktop. * **UX/Workflow Terminology**: Renaming permission modes to be more descriptive (e.g., "Code" mode was vague; "Auto accept edits" is precise). * **Documentation Structure**: Moving getting started content to specific quickstart pages. * **Technical Precision**: Using "Git worktree" instead of generic "Git isolation". 4. **Determine Impact Level**: * *Reasoning*: The changes are largely cosmetic and structural. The renaming of permission modes in the UI/Docs is the biggest functional "change" for developers, but it likely reflects a UI update rather than a logic change (e.g., the underlying functionality remains the same, just the label is clearer). The link changes affect navigation but not code execution. * *Verdict*: **Low**. Most changes improve readability and documentation structure. 5. **Determine Action Items**: * Update internal documentation/screenshots to reflect new permission mode names ("Auto accept edits", etc.). * Update links in internal wikis/tutorials pointing to the old `desktop` section (specifically anchors). * Be aware of the new "Git worktree" terminology if writing or debugging session isolation logic. * (Optional) Check the code block rendering if maintaining the docs, as the double `theme={null}` looks suspicious. 6. **Draft the Response (in Chinese)**: * *Summary*: 这次更新主要完善了桌面应用的功能描述，重命名了权限模式以提升清晰度，并优化了文档结构（如新增快速入门链接）。代码块中出现了重复属性的格式调整。 * *Themes*: * **术语规范化与功能高亮**: 权限模式名称更具描述性（如 `Code` 改为 `Auto accept edits`），并明确了 "Git worktree" 隔离机制。 * **产品能力增强展示**: 重点宣传了应用预览、PR 监控等新功能。 * **文档结构调整**: 安装和入门部分的链接指向更具体的页面。 * *Impact*: **Low**. 主要是UI术语和文档结构的优化，不涉及核心逻辑变更。 * *Action Items*: * 如果有相关教程或截图，需更新权限模式的新名称。 * 检查指向 Desktop 文档的内部链接是否需要更新（特别是 Get started 相关）。 * (可选) 向开发者反馈 `overview.md` 中代码块 `theme={null}` 重复的问题。 7. **Refine for "World-class Programmer" tone**: * Make it crisp. * Highlight the "Git worktree" nuance as it's a technical detail that matters. * Note the permission mode rename as a UX improvement. 8. **Final Polish (Chinese)**: * Summary: 此次更新主要针对 Claude Desktop 文档进行了术语重命名和结构优化，明确了 Git worktree 隔离机制，并修正了快速入门的链接跳转。 * Themes: * **权限模式命名更直观**: 将 `Code` 等模糊名称改为 `Auto accept edits` 等更具描述性的术语，降低认知负担。 * **技术细节精确化**: 明确使用 "Git worktree isolation" 而非泛泛的 "Git isolation"。 * **文档架构调整**: 入口链接指向更具体的 `desktop-quickstart` 页面，便于上手。 * Impact: Low. 主要是非破坏性的文档术语统一和链接修正。 * Actions: 更新相关技术文档/截图中的权限模式术语；修正内部链接引用。 *(Self-Correction during drafting)*: The `overview.md` change regarding `theme={null}` looks like a slight bug or specific builder artifact. I should mention it briefly as "formatting consistency". 9. **Final Output Generation**: (Proceeding to generate markdown).

1. **理解目标**：用户希望我作为一名世界级程序员来分析一份文档变更（定价页面的补丁）。输出需要是中文的简洁、有洞察力的 Markdown 格式分析。 2. **分析输入**： * **文件**：`about-claude/pricing.md`。 * **变更**： * **Fast Mode（快速模式）定价部分**： * *旧版*：Opus 4.6 快速模式有分级定价。≤ 200K token：$30/$150。> 200K token：$60/$225。 * *新版*：Opus 4.6 快速模式采用统一费率定价，覆盖“完整上下文窗口”。输入：$30/MTok，输出：$150/MTok。> 200K token 的溢价被移除。 * **长上下文定价部分**： * *旧版*：当 Opus 4.6、Sonnet 4.6/4.5/4 使用 1M 上下文窗口且请求 > 200K token 时，适用溢价长上下文费率。 * *新版*：阐明“标准速度”遵循 > 200K token 的溢价规则。*关键新增*：明确说明 Fast mode（快速模式）以*无额外长上下文费用*包含完整的 1M 上下文窗口（仅统一快速费率）。 3. **综合关键主题**： * **统一/简化的快速模式定价**：删除了快速模式的 >200K 溢价层级。 * **长上下文定价更优惠**：针对大上下文快速模式请求的成本降低。 * **清晰度/一致性**：阐明了标准速度和快速模式在长上下文方面的区别。 4. **评估影响**： * *等级*：高（财务影响）。降低 >200K token 快速模式请求的价格显著改变了使用大上下文的成本计算方式。 * *原因*：开发者使用 1M 上下文时可能支付的费用是预期的 1/2（针对输入）甚至更少（针对输出）。 5. **构思可执行事项**： * 审查使用大上下文（>200K）+ 快速模式的应用程序。 * 更新成本计算器。 * 考虑对现有大上下文用例启用快速模式，因为其边际成本更低了。 6. **起草回复（按要求使用中文）**： * *Summary（摘要）*：文档更新了 Claude Opus 4.6 Fast Mode 的定价结构，取消了针对超过 200K token 输入的额外溢价，改为统一费率。这显著降低了在大上下文窗口中使用 Fast Mode 的成本。 * *Key Themes（关键主题）*： * **统一快速模式费率**：移除了 Opus 4.6 快速模式中超过 200K token 的价格层级。 * **长上下文成本降低**：大上下文快速模式请求现在不再收取额外溢价。 * **文档清晰度**：阐明了“标准速度”与“快速模式”在 1M 上下文窗口方面的定价区别。 * *Impact Level（影响等级）*：**高**。虽然这不是破坏性的 API 变更，但它显著改变了潜在成本结构。对于依赖大上下文处理且需要低延迟的开发者来说，成本下降巨大（对于 >200K 输入，输入成本降幅达 50%，输出成本降幅更大）。 * *Action Items（可执行事项）*： * 重新评估使用 >200K 上下文时的成本计算，特别是针对 Opus 4.6 的快速模式。 * 考虑对以前因长上下文溢价而在快速模式下成本过高的大上下文用例启用快速模式。 * 检查预算估算，因为快速模式现在覆盖完整的 1M 上下文而无额外费用。 7. **润色**：确保语气专业（“世界级程序员”）且语言是自然的技术中文。 * *起草“Overall Summary”*：文档更新了 Opus 4.6 Fast Mode 的定价结构，取消了针对超长上下文（>200K tokens）的额外溢价，改为统一费率。 * *起草“Key Themes”*：长上下文成本降低、定价层级简化。 * *起草“Impact”*：High。财务影响巨大，特别是对大文档处理场景。 * *起草“Action Items”*：更新预算、重新评估 Fast Mode 的使用场景。 8. **最终打磨**：与提供的 Markdown 格式匹配。 * 检查表格变更：表格删除了“Context window”列并合并了行。 * 检查文本变更：“Fast mode pricing applies across the full context window, including requests over 200K input tokens.” 对比旧版表格外推逻辑。 * 检查长上下文文本变更：“at standard speed... automatically charged at premium... Fast mode... includes the full 1M context window at no additional long context charge.” *结论*：分析准确。将输出中文回复。

1. **Analyze the Request**: * **Role**: World-class programmer analyzing documentation changes. * **Input**: A diff for `CHANGELOG.md.md` showing a single new entry under version `2.1.49`. * **Language**: Chinese (请用中文回复). * **Format**: Markdown (Overall Summary, Key Themes, Impact Level, Action Items). 2. **Analyze the Input Data**: * **File**: `CHANGELOG.md.md`. * **Change**: Added a changelog entry for version `2.1.49`. * **Specific Additions**: * Improved MCP OAuth authentication (step-up auth, discovery caching, reduced network requests). * Added `--worktree` / `-w` flag for isolated git worktree usage. * Subagents support `isolation: "worktree"`. * Added Ctrl+F to kill background agents. 3. **Drafting the Content (Iterative translation to Chinese)**: * **Overall Summary**: * *Draft*: This update mainly optimizes authentication performance for MCP OAuth, introduces git worktree isolation features for developers, and adds a shortcut key to manage background agents. * *Refinement (World-class tone)*: 本次更新显著优化了 MCP OAuth 认证性能与网络效率，同时引入了 Git Worktree 隔离功能以提升多分支工作流的安全性，并增加了管理后台代理的快捷键。 * **Key Themes**: * *Performance/Efficiency*: OAuth improvements (caching, step-up auth). * *Workflow/Isolation*: Git worktree support (CLI flag and subagent isolation). * *User Experience/Control*: Ctrl+F to kill agents. * *Chinese Translation*: * 认证性能优化：通过缓存和 step-up auth 机制减少冗余网络请求。 * Git 工作流增强：支持在独立的 Git Worktree 中运行 Claude 或子代理，提升代码隔离性。 * 代理管理：引入快捷键（Ctrl+F）以便更快速地终止后台代理进程。 * **Impact Level**: * *Assessment*: * OAuth: Good for performance, but probably invisible to user unless they were seeing slowness. Medium impact for MCP users. * Worktree: Medium/High impact for developers working with multiple branches or testing code in isolation. * Ctrl+F: Low impact, nice convenience. * Overall: Medium (since worktree is a significant workflow changer for some, and perf is always good). * *Reasoning*: Adds new capabilities (worktree) and performance gains without breaking existing behavior. * *Chinese*: Medium (中等)。虽然主要是功能增强和性能优化，但引入的 Git Worktree 隔离功能对特定工作流影响显著。 * **Action Items**: * *Draft*: Check out the `-w` flag. Try `isolation: worktree` in config. Remember Ctrl+F. * *Refinement*: 1. Try using `claude -w` or `--worktree` when working on sensitive features or multiple branches. 2. Update subagent configurations to utilize `isolation: "worktree"` for safer sandboxing. 3. Note the reduced latency in MCP connections (automatic benefit). 4. Use Ctrl+F (twice) to quickly kill stuck background agents. * *Chinese*: 1. 在处理敏感功能或需要同时操作多个分支时，尝试使用 `claude -w` 或 `--worktree` 启动。 2. 更新子代理配置，利用 `isolation: "worktree"` 实现更安全的沙箱环境。 3. 体验 MCP 连接速度的提升（得益于发现缓存）。 4. 记住 Ctrl+F（连按两次）快捷键，用于快速强制终止后台代理。 4. **Final Review**: * Check constraints: Concise? Yes. Insightful? Yes. Markdown? Yes. Chinese? Yes. Developer focused? Yes. 5. **Construct Final Output**. (Proceed to generate output based on step 3).

1. **Analyze the Request:** * **Role:** World-class programmer, expert in developer tools/docs. * **Task:** Analyze documentation changes (batch of 12 pages) and summarize what changed and why it matters. * **Format:** Markdown, concise, insightful. * **Language:** Chinese (as requested: "请用中文回复"). * **Sections Required:** Overall Summary, Key Themes, Impact Level (with reasoning), Action Items (max 5). 2. **Analyze the Source Data (Diff Content):** * **Page 1: `cli-reference.md`** (+1/-0): * Added `--worktree` / `-w` flag description. * Function: Starts Claude in an isolated git worktree. * **Page 2: `common-workflows.md`** (+31/-34): * Major rewrite of the "Run parallel Claude Code sessions with Git worktrees" section. * Shift from manual Git commands (`git worktree add ...`) to using the new `--worktree` flag. * Clarifies automatic cleanup (remove if no changes, prompt if changes). * Adds instructions on `.gitignore` for `.claude/worktrees/`. * Retains manual management section for advanced use cases. * **Page 3: `desktop.md`** (+1/-1): * Updated table comparing CLI vs. Desktop. * Changed CLI "Session isolation" description from "manual via git worktrees" to "[`--worktree`](/en/cli-reference) flag". * **Page 4: `hooks.md`** (+64/-33): * New event: `ConfigChange`. * Fires when config files change during a session. * Matcher details added for `ConfigChange` (filtering by `user_settings`, `project_settings`, etc.). * Updated diagram (likely just a URL change/redraw, but content implies the lifecycle includes config changes now). * **Page 5: `hooks-guide.md`** (+9/-0): * New example use case: "Audit configuration changes". * Code example using `jq` to log config changes to a file. * Mentions blocking changes with exit code 2. * **Page 6: `interactive-mode.md`** (+18/-17): * Updated shortcuts table. * Added `Ctrl+F` (Kill all background agents, needs double press). * Minor formatting reflows. * **Page 7: `plugins.md`** (+7/-0): * New file structure support: `settings.json` at plugin root. * Purpose: Apply default settings (currently only `agent` key) when plugin is enabled. * Explanation: Allows a plugin to change default behavior (system prompt, tools, model) by activating a custom agent. * **Page 8: `plugins-reference.md`** (+11/-9): * Updated plugin file structure reference to include `settings.json`. * Updated "File locations reference" table. * **Page 9: `security.md`** (+1/-0): * Added suggestion to audit/settings changes using `ConfigChange` hooks. * **Page 10: `settings.md`** (+1/-0): * Added new env var: `CLAUDE_CODE_SIMPLE`. * Mode: Minimal system prompt, limited tools (bash, read, edit). Disables MCP, attachments, hooks, CLAUDE.md. * **Page 11: `sub-agents.md`** (+2/-0): * Added new config options for subagents: * `background`: Always run in background. * `isolation`: Run in a temporary git worktree. * **Page 12: `vs-code.md`** (+3/-7): * Updated "Use git worktrees for parallel tasks" section. * Simplified instructions to use `claude -w` instead of manual git commands. 3. **Synthesize Key Themes:** * **Git Worktree Integration:** Major improvement. Manual git commands are abstracted away into a CLI flag (`--worktree`). Automatic cleanup is a huge UX win. * **Configuration Auditing/Control:** New `ConfigChange` hook allows monitoring or blocking setting changes. New `CLAUDE_CODE_SIMPLE` env var allows a "safe/sandboxed" mode. * **Plugin Extensibility:** Plugins can now ship default settings (specifically setting the default agent). * **Agent Control:** Subagents can now be forced to run in background or in isolated worktrees automatically. * **Keyboard Shortcut:** New `Ctrl+F` to kill background agents. 4. **Draft the Analysis (in Chinese):** * *Overall Summary:* The update significantly streamlines parallel development workflows by introducing the `--worktree` flag for automatic git worktree management. It also enhances security and configuration control with the new `ConfigChange` hook, `CLAUDE_CODE_SIMPLE` mode, and expanded plugin capabilities. * *Key Themes:* * **Simplified Parallel Workflows:** The `--worktree` flag automates the creation, branching, and cleanup of git worktrees, replacing complex manual commands across multiple docs. * **Enhanced Configuration Control:** New `ConfigChange` hooks enable auditing or blocking of settings changes in real-time; new `CLAUDE_CODE_SIMPLE` mode restricts Claude to core tools. * **Agent & Plugin Improvements:** Plugins can now ship default settings (e.g., default agent), and subagents support automatic background execution and worktree isolation. * **UI/UX Refinements:** Added `Ctrl+F` shortcut to force-stop background agents. * *Impact Level:* **Medium/High**. * *Reasoning:* The `--worktree` flag is a major workflow improvement for users handling multiple branches. The `ConfigChange` hook and `Simple` mode are significant for enterprise security and compliance. Plugin default settings improve the developer experience for plugin authors. * *Action Items for Developers:* * Update workflows to use `claude -w <name>` for parallel tasks instead of manual `git worktree` commands. * Add `.claude/worktrees/` to `.gitignore`. * Consider implementing `ConfigChange` hooks if you need to audit or lock down Claude settings. * Explore `CLAUDE_CODE_SIMPLE=1` for environments where you need restricted tool access. 5. **Refine and Polish (Markdown & Language):** * Ensure terms like "Git worktree", "Hooks", "Subagents" are used correctly in Chinese context or kept in English where appropriate for technical accuracy. * Make it concise. *(Self-Correction during drafting)*: The prompt asks for "Impact level". I'll say "High" because the worktree automation changes the fundamental way people use the tool for multi-tasking, which is a core developer workflow. The `ConfigChange` hook is also a big deal for security-conscious teams. *Translation check:* * "Git worktree" -> Git 工作树 * "Hooks" -> 钩子 * "Subagents" -> 子代理 * "Isolation" -> 隔离 6. **Final Output Generation:** (matches the structure requested). * Summary: 本次更新引入了 `--worktree` 标志以简化并行开发工作流，并增强了安全与配置控制能力。 * Themes: Worktree 自动化, 配置审计与安全, 插件与代理增强. * Impact: High. * Actions: Use `-w`, add to gitignore, audit hooks, simple mode. 7. **Final Review against constraints:** * Single batch analysis? Yes. * Concise? Yes. * Markdown? Yes. * Chinese? Yes. * 12 pages analyzed? Yes. Looks good. Proceed to generate output.
