Changes on 2026-06-25

1. **Analyze the Request:** * **Role:** World-class programmer, expert in dev tools/docs. * **Task:** Analyze a batch of 3 documentation changes (`claude-code-on-the-web.md`, `monitoring-usage.md`, `CHANGELOG.md.md`). * **Output Format:** Markdown, concise, insightful, Chinese language. * **Specific Sections Required:** Overall Summary, Key Themes, Impact Level (with reasoning), Action Items (max 5). 2. **Analyze the Changes:** * **Page 1: `claude-code-on-the-web.md` (2 additions, 2 deletions)** * *Change 1:* "Team and Enterprise **admins**" -> "Team and Enterprise **Owners**". * *Change 2:* "your **admin** has not enabled" -> "an **Owner** has not enabled". * *Significance:* Terminology clarification. It tightens the definition of who has permission to manage `/web-setup` and cloud sessions. It distinguishes between general "admins" and specific "Owners" (likely specific to the billing/account owner role in the platform). * **Page 2: `monitoring-usage.md` (1 addition, 1 deletion)** * *Change:* Added a long sentence explaining how to filter `token` or `cost` metrics by `query_source = "main"` to avoid misattributing commits when a session spans multiple models. * *Significance:* Technical correction/clarification for observability. It fixes a potential logic error in how developers might query metrics. If a subagent uses a different model, you don't want the main commit attributed to that subagent's model if the join logic isn't careful. * **Page 3: `CHANGELOG.md.md` (16 additions, 0 deletions)** * *Version:* 2.1.193. * *Key Additions:* * `autoMode.classifyAllShell`: New setting. * Auto-mode denials: Better visibility (transcript, toast, `/permissions`). * **OpenTelemetry:** New `claude_code.assistant_response` event. *Crucial detail:* Redacted by default, but respects `OTEL_LOG_USER_PROMPTS` fallback. If you log prompts, you will now log responses on upgrade unless you explicitly set `OTEL_LOG_ASSISTANT_RESPONSES=0`. * Bash mode: Live file path autocomplete. * MCP: Auth startup notice. Auto-reconnect on 401/403. * Fixes: Backgrounding issues, agent panel, `/model` UI state. * Improvements: Background agents behavior, plugin auto-rename. 3. **Synthesize and Structure (Drafting in Chinese):** * **Overall Summary:** The update focuses on terminology refinement, observability accuracy, and feature enhancements (especially regarding background agents, auto-mode, and telemetry). Most critically, it includes a breaking change regarding telemetry logging behavior for response content. * *Chinese Draft:* 本次更新主要涉及权限术语修正、监控指标查询准确性的提升以及多项功能增强（特别是后台代理、自动模式和遥测功能）。最关键的是关于 OpenTelemetry 日志行为的变更，可能导致升级后默认记录响应内容。 * **Key Themes:** * *Terminology/Permissions:* Admin -> Owner distinction. * *Observability/Logging:* Fixing metric joins and adding response logs (with opt-out implications). * *Agent/Backgrounding:* Several fixes and improvements to how background agents work and survive sessions. * *MCP/Auth:* Better authentication handling. * **Impact Level:** * *Level:* Medium to High (due to the logging implication). * *Reasoning:* The `OTEL_LOG_ASSISTANT_RESPONSES` behavior is a significant privacy/security consideration for enterprises. The permission change is semantic but affects compliance. The metric join fix is important for data accuracy. * **Action Items:** * Check telemetry settings (`OTEL_LOG_ASSISTANT_RESPONSES`) if privacy is a concern. * Update metric queries for `commits` per model using `query_source`. * Review the new `autoMode` settings if security policies are strict. * Update internal documentation regarding "Owners" vs "Admins". 4. **Refining the Content (Self-Correction/Polishing):** * *Refining Action Item 1:* Make sure to highlight the specific env var. * *Refining Action Item 2:* Be specific about the "query_source is 'main'" part. * *Refining Key Themes:* Group the fixes into "Background Agents & Workflow" and "Observability & Compliance". 5. **Final Output Generation (matching the requested format):** * *Summary:* 本次文档更新主要围绕权限术语修正、监控数据准确性说明以及版本 2.1.193 的功能发布。其中最关键的变化涉及 OpenTelemetry 日志记录逻辑的调整，这可能影响企业级的数据隐私合规。 * *Themes:* 权限定义更精确, 遥测与监控, 后台任务与代理体验, 自动化与安全控制. * *Impact:* Medium/High. Reason: The `OTEL_LOG_ASSISTANT_RESPONSES` log logic change is a potential privacy surprise. * *Actions:* Explicitly set `OTEL_LOG_ASSISTANT_RESPONSES=0`, update metric queries, verify "Owner" permissions. 6. **Final Polish (Language Check):** Ensure the tone is professional and "world-class programmer" style. *(Self-Correction during drafting Chinese response)*: Make sure to emphasize *why* the metric change matters (avoiding wrong attribution). Make sure to emphasize *why* the Owner change matters (access control granularity). Let's write the final response.

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Task:** Analyze documentation changes as a single batch. * **Format:** Concise, insightful analysis in markdown. * **Language:** Chinese. * **Scope:** 38 changed pages (provided via diffs). * **Key Output Elements:** Overall Summary, Key Themes, Impact Level, Action Items. 2. **Scan and Analyze the Diffs:** * `cli-reference.md`: Added `--background` as an alias for `--bg`. * `monitoring-usage.md`: Added `"agents_view"` as a valid value for `start_type` attribute. * `overview.md`, `quickstart.md`, `setup.md`: Added troubleshooting tips for Windows installation (syntax error, 403, curl errors). * `third-party-integrations.md`: Added a link to "Feature availability" page. * `about-claude/models/overview.md`: Massive rebranding/renaming: "Vertex AI" $\rightarrow$ "Google Cloud" in IDs and descriptions. Removed "Priority Tier" column from the comparison table (indicates a change in service structure). * `about-claude/models/migration-guide.md`: "Vertex AI" $\rightarrow$ "Google Cloud". Removed "Priority Tier" reference. * `about-claude/pricing.md`: "Vertex AI" $\rightarrow$ "Google Cloud". Removed "Priority Tier" reference. * `about-claude/model-deprecations.md`: "Vertex AI" $\rightarrow$ "Google Cloud". * `api/overview.md`: "Vertex AI" $\rightarrow$ "Google Cloud". Renamed platform name to "Agent Platform". Removed specific "Priority Tier" mention from limits description. Request size limit note updated. * `api/messages.md`: "Vertex AI" $\rightarrow$ "Google Cloud" references (implied by context, actually diffs show changes to tool definitions and removing old models). *Correction*: The diffs specifically show removing old models (claude-opus-4-0, claude-3-haiku-20240307, etc.) from the list. Added `code_execution_20260521` to allowed_callers. Added a new `CodeExecutionTool20260521` object. * `api/messages/count_tokens.md`: Same as `api/messages.md` (remove old models, add `CodeExecutionTool20260521`). * `api/messages/batches/create.md`: Same as `api/messages.md`. * `api/rate-limits.md`: "Vertex AI" $\rightarrow$ "Google Cloud". * `api/service-tiers.md`: **Major Change**. Added warning that Priority Tier is no longer available for purchase. Existing commitments honored. * `build-with-claude/overview.md`, `build-with-claude/text-generation.md`: "Vertex AI" $\rightarrow$ "Google Cloud". * `build-with-claude/vision.md`: Significant content reduction/rewrite. Removed detailed examples, limits, and cost calculations. Added link to coordinate-based workflows. Changed "Vertex AI" $\rightarrow$ "Google Cloud". * `build-with-claude/pdf-support.md`: "Vertex AI" $\rightarrow$ "Google Cloud". * `build-with-claude/extended-thinking.md`: "Vertex AI" $\rightarrow$ "Google Cloud". * `build-with-claude/prompt-caching.md`: "Vertex AI" $\rightarrow$ "Google Cloud". * `build-with-claude/batch-processing.md`: "Vertex AI" $\rightarrow$ "Google Cloud". * `build-with-claude/context-windows.md`: "Vertex AI" $\rightarrow$ "Google Cloud". * `build-with-claude/search-results.md`: "Vertex AI" $\rightarrow$ "Google Cloud". 3. **Synthesize Key Themes:** * **Theme 1: Rebranding "Vertex AI" to "Google Cloud".** This is the most pervasive change across almost every page. It affects API IDs, platform names, and references in pricing/model tables. * **Theme 2: Service Tier Changes.** Priority Tier is now closed for new purchases (retained for existing). References to "Priority Tier" in model comparison tables have been removed. * **Theme 3: Tool & Model Updates.** * Removed specific old model IDs from API lists (Opus 4.0, Sonnet 4.0, Haiku 3.5 base IDs without dates, etc.). * Added a new `CodeExecutionTool20260521` tool definition. * **Theme 4: Documentation Refinement.** * Windows install troubleshooting added. * Vision guide heavily simplified/refactored. * CLI alias `--background` added. 4. **Determine Impact Level:** * **Rebranding (Vertex AI -> Google Cloud):** Low/Medium impact for code (unless strict string matching on docs), but important for mental model and future compatibility. Platform ID didn't necessarily change in the API schema itself (just the label), but docs explicitly renamed "Vertex AI ID" to "Google Cloud ID". * **Priority Tier Closure:** High impact for *new* users wanting guaranteed capacity, but Low/Medium for existing users. It signals a shift in product availability. * **Old Model Removal:** Medium impact. If users are hardcoding specific dated IDs or relying on them being in the "main" list, they need to update, though they are likely retired/deprecated anyway. * **New Tool Version:** Low impact for existing code, High for those wanting the latest features. * **Conclusion:** **Medium** overall. The rebranding is widespread but mostly cosmetic/labeling. The Priority Tier change is a business/policy update affecting future architecture decisions. The tool update is standard evolution. 5. **Draft Action Items:** * Update internal documentation/tutorials referencing "Vertex AI" to "Google Cloud". * Check if you plan to buy Priority Tier – it's no longer available (contact sales for alternatives). * Review usage of "retired" model IDs (e.g., Haiku 3.5, Opus 4.0) as they are being cleaned up from docs. * Update CLI scripts to support `--background` alias (optional). * Be aware of the new `code_execution_20260521` tool version if building agentic systems. 6. **Drafting the Response (in Chinese):** * *Summary:* 本次更新主要集中在 Google 合作伙伴平台的品牌重塑，明确了“优先级服务层级”的可用性变化，并清理了旧版模型 ID。此外，引入了新的代码执行工具版本，并改进了 CLI 和安装文档。 * *Themes:* * **品牌重塑：** 文档中广泛将 "Vertex AI" 重命名为 "Google Cloud"，涉及 API ID、平台名称及描述。 * **服务层级调整：** Priority Tier（优先级层级）不再对新用户开放购买，仅保留现有承诺；相关表格列已被移除。 * **模型与工具更新：** 清理了部分旧版模型（如 Opus 4.0, Haiku 3.5 base ID）的文档引用；新增 `code_execution_20260521` 工具定义。 * **文档优化：** 简化了视觉功能指南，增加了 Windows 安装故障排除建议，并新增了 CLI 别名。 * *Impact:* Medium. (Reasoning: 主要是品牌变更和产品政策更新，而非 API 结构的破坏性更改，但 Priority Tier 的停止销售可能影响架构规划。) * *Action Items:* * 更新内部文档或代码注释，将 "Vertex AI" 替换为 "Google Cloud"。 * 若计划采购 Priority Tier，需联系销售团队确认替代方案（该层级现已停售）。 * 检查代码是否依赖已清理的旧版模型 ID，并考虑升级到当前活跃模型。 * 如果正在构建代理系统，留意新的 `code_execution_20260521` 工具版本。 * 在 Windows 环境下安装遇到错误时，参考新增的故障排除链接。 7. **Review and Refine:** * The prompt asks for "Concise, insightful analysis". * The distinction between "Vertex AI" and "Google Cloud" is the biggest bulk change. * The Priority Tier change is subtle but significant business logic. * The `CodeExecutionTool20260521` adds specific technical detail. * The vision page edit suggests a move towards modularity (removing embedded detailed examples). * Check translation accuracy: "Priority Tier" -> "优先级层级" or "优先服务". Let's use "优先级层级". 8. **Final Polish (Markdown formatting):** Ensure headers and bullets are clean. (Self-correction: Ensure the distinction between "breaking" and "non-breaking" is clear. The renaming is non-breaking for the API usually, but breaking for string matching if strict). * *Refined Summary:* 此次文档更新主要涉及 Google Cloud 合作伙伴平台的品牌重塑（从 Vertex AI 更名），Priority Tier 服务的停售，以及 API 模型的清理与工具版本更新。 * *Refined Action Items:* (Keep them actionable). Let's generate the output.

1. **Understand the Goal**: The user wants a concise, insightful analysis of a specific documentation change in Markdown format, focusing on developer impact. The response must be in Chinese. 2. **Analyze the Input Data**: * **Page**: `hooks-guide.md` * **Change**: Added a comment block `{/* min-version: 2.1.191 */}` and a sentence explaining that in Claude Code v2.1.191+, tool-name matchers can use `|` or `,` interchangeably. * **Context**: The text is explaining how to set up a Prettier hook. The original text used `Edit|Write`. The new text clarifies that `Edit,Write` is also valid in newer versions. 3. **Determine the "Why"**: This is a usability enhancement. It informs developers that they have flexibility in syntax, specifically regarding the separator character for matchers. It also introduces a conditional rendering mechanic (implied by the comment syntax, though the comment itself is likely for the documentation rendering engine to show/hide content). 4. **Drafting the Analysis (Internal Monologue/Rough Draft)**: * *Overall Summary*: The docs were updated to mention that version 2.1.191+ supports comma-separated matchers alongside pipe-separated ones. It's a small syntax flexibility update. * *Key Themes*: Syntax flexibility, version compatibility. * *Impact*: Low. It's just an alternative syntax. * *Action Items*: Check version if using commas, maybe update configs (optional). 5. **Refining for the Persona (World-class Programmer)**: * *Tone*: Professional, precise, developer-centric. * *Summary*: Needs to be sharp. "Added clarification regarding separator syntax for tool-name matchers in Claude Code v2.1.191." * *Themes*: Syntax evolution, backward compatibility. * *Impact*: Low. It doesn't break anything, just adds an option. * *Action Items*: Developers can now use commas, but it's not mandatory. Note the version requirement. 6. **Translating to Chinese**: * *Summary*: 文档新增了对 Claude Code v2.1.191 版本后语法特性的说明，指出工具名称匹配器中逗号（`,`）与管道符（`|`）可以互换使用。 * *Themes*: 语法灵活性, 版本兼容性. * *Impact*: Low. 不影响现有功能，仅提供额外便利。 * *Action Items*: 如果使用新语法需确认版本，可选性更新配置。 7. **Formatting (Markdown)**: * Structure as requested: 1. Overall Summary 2. Key Themes 3. Impact level 4. Action items 8. **Final Polish (Self-Correction during drafting)**: * *Check*: Did I catch the comment syntax `{/* min-version: 2.1.191 */}`? Yes, it implies the documentation might be dynamically rendered based on version, but the *content* change is about the syntax change. * *Refinement on Action Items*: Since it says "you can also write", it's optional. So "Migrating" isn't the right word. "Awareness" is better. 9. **Final Output Generation**: 1. **Overall Summary**: `hooks-guide.md` 更新了关于工具匹配器语法的说明，指出在 Claude Code v2.1.191 及更高版本中，逗号（`,`）和管道符（`|`）在定义工具名称列表时可互换使用。 2. **Key Themes**: * **语法灵活性**: 提供了更标准化的分隔符选项（逗号）。 * **版本感知**: 明确了特定语法特性所需的最小版本号。 3. **Impact level**: **Low** * **Reasoning**: 这是一个非破坏性的增强，提供了新的语法选项，但并未废弃旧的 `|` 分隔符用法。现有配置无需修改。 4. **Action items**: * 无需立即采取行动，现有 `Edit|Write` 语法依然有效。 * 若偏好使用逗号分隔符（`Edit,Write`），请确保 Claude Code 版本不低于 v2.1.191。 * 复制配置代码时注意版本说明，避免在旧版本上出现语法错误。 10. **Final Review against constraints**: Concise? Yes. Insightful? Yes. Markdown? Yes. Chinese? Yes.

1. **Understand the Goal**: The user wants a concise, insightful analysis of a batch of documentation changes (6 pages) for Claude Code. The output must be in Markdown format, in Chinese, focusing on what matters to developers. 2. **Analyze Each Page's Diff**: * **Page: costs.md** * *Change*: Removed a specific mention of "LiteLLM" as a recommended tool for tracking spend on Bedrock/Vertex/Foundry. Added a general statement that organizations using an LLM gateway can track spend there. * *Significance*: De-emphasizes a specific third-party tool (LiteLLM) in favor of the broader LLM gateway concept which seems to be a first-class feature now. * **Page: iam.md** * *Change*: Updated the scope of `apiKeyHelper`, `ANTHROPIC_API_KEY`, and `ANTHROPIC_AUTH_TOKEN`. Previously "terminal CLI sessions only". Now "CLI and surfaces that wrap it, including VS Code extension, Agent SDK, and GitHub Actions". Clarified Claude Desktop uses OAuth unless using an organization-distributed third-party inference configuration. * *Significance*: Important auth expansion. API keys now work in more places (VS Code, Actions, SDK), not just raw CLI. * **Page: llm-gateway.md (Major Changes)** * *Change*: Significant restructuring and rewrite. Title changed from "LLM gateway configuration" to "LLM gateways". * Moved specific technical requirements (API formats, request headers) to a separate protocol reference (implied by links like `/en/llm-gateway-protocol`). * Reframed the page as a high-level overview of *why* and *how* gateways work, rather than just a configuration guide. * Added clear navigation for different user roles (Developers vs. Admins vs. Gateway Configurers). * Simplified the explanation of the architecture (Claude Code -> Gateway -> Provider). * *Significance*: This is a structural update. The documentation is splitting into conceptual pages vs. technical reference pages. It makes the ecosystem easier to navigate but hides the deep technical specs behind links. * **Page: model-config.md** * *Change*: Updated link text/names. "LLM gateway configuration" -> "LLM gateways". Updated internal links to point to specific protocol sections (e.g., `#model-selection` -> `/en/llm-gateway-protocol#model-discovery`). * *Significance*: Consistency update to match the `llm-gateway.md` restructuring. * **Page: settings.md** * *Change*: Clarified that `apiKeyHelper` is a custom command run through the system shell (`/bin/sh` or `cmd`). * *Significance*: Technical precision fix for Windows vs. Unix compatibility. * **Page: third-party-integrations.md** * *Change*: Updated link to "LLM gateways". Updated example configs: Foundry now uses `ANTHROPIC_FOUNDRY_API_KEY` instead of `CLAUDE_CODE_SKIP_FOUNDRY_AUTH`. Vertex example added `ANTHROPIC_VERTEX_PROJECT_ID` and `CLOUD_ML_REGION`. * *Significance*: Config updates. The Foundry change suggests a shift in how authentication interacts with gateways (using a key explicitly rather than skipping auth entirely). 3. **Synthesize Key Themes**: * **LLM Gateway Promotion**: Gateway support is now a first-class, central feature. Documentation is restructured to separate high-level concepts from technical protocols. * **Authentication Expansion**: API keys (`apiKeyHelper`) are now supported beyond the terminal CLI (VS Code, SDK, GitHub Actions). * **Documentation Restructuring**: Moving detailed specs (like headers/formats) to reference pages to improve readability. * **Deprecation/Generalization**: Removing specific endorsements (LiteLLM) in favor of general capability descriptions. 4. **Determine Impact Level**: * *Level*: Medium. * *Reasoning*: While mostly docs, the IAM change regarding where API keys apply (VS Code, Actions) is a functional/feature expansion that matters to developers setting up their environments. The Gateway restructuring is significant for understanding the architecture but doesn't break existing setups. The Foundry config change might require action for some users. 5. **Draft Action Items**: * Check IAM/Auth settings if using API keys in VS Code, Actions, or SDK (now supported). * Review LLM Gateway setup if using Bedrock/Vertex/Foundry (docs moved). * Update Foundry environment variables if using a gateway (switch from `SKIP_FOUNDRY_AUTH` to specific API key). * Note that LiteLLM mention was removed (use generic gateway docs instead). 6. **Draft the Response (in Chinese)**: * *Overall Summary*: Documentation focused on elevating LLM Gateway support to a first-class feature, expanded API key authentication scope beyond CLI, and restructured technical specifications. * *Key Themes*: * LLM Gateway integration (Refined architecture, simplified setup). * Authentication expansion (VS Code, SDK, Actions). * Documentation restructuring (Concept vs Protocol). * Cloud provider config updates (Foundry/Vertex). * *Impact*: Medium. Functional scope expansion for auth and architectural clarifications. * *Action Items*: * Update auth logic for VS Code/Actions. * Adjust Foundry gateway env vars. * Consult new gateway docs. 7. **Refine the Output**: Ensure tone is professional and developer-focused. Use Markdown headers and lists as requested. * *Self-Correction during drafting*: Ensure the distinction between "LLM Gateway configuration" (old) and "LLM gateways" (new) is clear. Make sure to mention the specific environment variable change for Foundry as it's a concrete code change. 8. **Final Polish (Simulated Output)**: * Summary: Documentation overhaul highlighting LLM Gateway architecture, expanding API key usage scope, and updating cloud provider integration examples. * Themes: Gateway centrality, Auth broadening, Docs restructuring. * Impact: Medium. * Actions: Update env vars for Foundry, utilize API keys in new surfaces, review gateway protocol docs. 9. **Generate Output**. (Proceed to generate the response based on these points).

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Task:** Analyze a batch of 9 documentation page diffs. * **Output Format:** Markdown, concise, insightful. * **Language:** Chinese (as requested: "请用中文回复"). * **Structure:** 1. Overall Summary, 2. Key Themes, 3. Impact Level, 4. Action Items. 2. **Analyze the Input Diffs (Page by Page):** * **`amazon-bedrock.md`:** * *Change:* Clarified merge behavior when listing a specific Mantle model ID (e.g., `anthropic.claude-haiku-4-5`) alongside its alias (`haiku`). Added explanation that they resolve to the same family and only the specific entry is kept. * *Significance:* Clarification on model selection logic in settings. * **`checkpointing.md`:** * *Change:* Added new section "Rewind past a cleared conversation". * *Feature:* v2.1.191 allows resuming the session active *before* a `/clear` command via a specific menu entry. * *Significance:* UX improvement for session recovery. * **`discover-plugins.md`:** * *Change:* Refined text regarding the "Not used recently" plugin group. * *Detail:* Clarified the duration condition: "haven't invoked in at least two weeks, over a span of at least 10 sessions". * *Significance:* Precision in how "unused" is calculated. * **`hooks.md`:** * *Change:* Updated table for `matcher` field evaluation. * *Feature:* v2.1.191 supports spaces, commas, and optional surrounding whitespace in exact string lists (separated by `|` or `,`). * *Constraint:* `FileChanged` and `StopFailure` events still only accept `|` as a separator. * *Significance:* Easier configuration syntax for hooks. * **`interactive-mode.md`:** * *Change:* Updated `/` command in NORMAL mode navigation table. * *Feature:* v2.1.191 adds a hint in the empty search prompt. * *Significance:* UX improvement/hint visibility. * **`mcp.md`:** * *Change 1:* Added v2.1.191 retry logic for capability discovery requests (`tools/list`, `prompts/list`, `resources/list`) post-connection. * *Change 2:* Updated `claude mcp login` behavior. It now detects if a browser is unavailable (SSH/Linux no-display) automatically, printing the URL without needing `--no-browser`. `--no-browser` forces the prompt even if a browser is found. * *Significance:* Reliability improvement for MCP connections and authentication flow. * **`model-config.md`:** * *Change 1:* Clarified text about `enforceAvailableModels` behavior when the list is non-empty but invalid (enforcement is skipped, Default resolves to account default). * *Change 2:* Text polish ("Both restrictions apply together" instead of "The two mechanisms compose"). * *Change 3:* Text polish ("shown as a normal error" instead of "surfaces as a normal error"). * *Significance:* Clarity updates on error handling and policy enforcement. * **`sandboxing.md`:** * *Change 1:* Clarified `sandbox.credentials` text regarding grouping. * *Change 2:* v2.1.191 update to Domain restrictions: approving a domain allows it for the *rest of the session*, preventing repeated prompts. * *Significance:* UX improvement (fewer prompts) and documentation clarity. * **`settings.md`:** * *Change:* Added row in "Security-enforcement fields" table for `sandbox.credentials`. * *Feature:* v2.1.191 behavior: invalid entries are stripped with a warning; valid subset enforced. Wholly invalid value dropped with warning. * *Significance:* Consistency in how invalid security settings are handled (fail-open or partial enforcement). 3. **Synthesize Findings:** * **Common Thread:** The version **v2.1.191** appears repeatedly. This update focuses on UX refinements (fewer prompts, better hints), robustness (MCP retries, better settings validation), and syntax flexibility (hooks). * **Specific Features:** Session recovery after `/clear`, automatic browser detection for auth, improved domain approval persistence, relaxed syntax for hook matchers. 4. **Drafting the Content (in Chinese):** * *Overall Summary:* The updates primarily introduce features and clarifications for version v2.1.191, focusing on improving user experience (session recovery, fewer prompts), enhancing system robustness (MCP retries), and refining syntax (hooks). * *Key Themes:* * **v2.1.191 Feature Release:** Several new capabilities land here. * **UX Enhancements:** `/resume` to recover cleared sessions, persistent domain approvals, browser detection for auth. * **Reliability & Robustness:** Retries for MCP discovery, better handling of invalid security settings. * **Syntax Flexibility:** Hooks now support comma separators and whitespace. * *Impact Level:* **Medium**. The changes improve quality of life and configuration management, but don't appear to introduce breaking changes for existing workflows. The logic updates are additive or clarify edge cases. * *Action Items:* * Review `sandbox.credentials` configuration for new validation logic. * Simplify hook matchers using new comma/space syntax. * Update user guides to mention the new `/resume` capability for cleared sessions. 5. **Refining the Output (Self-Correction during drafting):** * *Check:* Did I miss anything? * *Observation:* The `interactive-mode` change is minor (a hint). The `model-config` changes are mostly text clarifications. The `mcp` login change removes the need for a manual flag in many cases. * *Tone:* Professional, "world-class programmer". * *Language:* Ensure natural-sounding Chinese technical terms (e.g., "Hook matchers" -> "Hook 匹配器", "Fallback" -> "回退", "Sandbox" -> "沙箱"). 6. **Final Polish (Markdown Structure):** * **Summary:** 此次更新主要集中在 **v2.1.191** 版本的功能发布与文档澄清，增强了用户体验（如会话恢复、减少认证步骤）、提升了系统鲁棒性（MCP 重试机制），并放宽了配置语法（如 Hook 匹配器）。 * **Themes:** * **版本 v2.1.191 新特性：** 多项核心改进与此版本相关。 * **用户体验优化：** 新增从 `/clear` 命令后恢复会话的功能，沙箱域名批准后的会话级持久化，以及 SSH 环境下的浏览器自动检测。 * **语法与配置灵活性：** Hook 匹配器现在支持逗号分隔符和空格，简化配置。 * **稳定性增强：** MCP 服务器连接后的能力发现请求增加了重试机制；对无效安全配置的处理更加优雅。 * **Impact:** **Medium**（中等影响）。大多数更改属于体验增强和配置逻辑澄清，不具备破坏性变更，但能显著提升日常开发效率和系统稳定性。 * **Action Items:** * 利用新版 Hook 语法简化匹配器配置（支持逗号和空格）。 * 了解 `sandbox.credentials` 在 v2.1.191 中对无效条目的处理逻辑变更。 * 体验并文档化 `/resume` 在恢复已清除会话时的使用场景。 7. **Final Output Generation.** (Proceed to generate output based on step 6).
