Changes on 2026-05-20

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** A batch of documentation changes for `desktop.md`, `hooks.md`, `fine-grained-tool-streaming.md`, and `CHANGELOG.md.md`. * **Output Format:** Markdown, concise, insightful analysis. * **Language:** Chinese (as requested in the prompt: "请用中文回复"). * **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 bullets). 2. **Analyze the Content:** * **`desktop.md` (Changes: 2 paragraphs)** * *Change 1 (Prompt box behavior):* Refined the description of user interruption/redirection. Now allows sending a correction *without* stopping the current action; Claude reads it after the current step completes. This is a UX improvement in how the "redirect" feature works. * *Change 2 (`/desktop` command availability):* Restricted the `/desktop` command (moving CLI session to Desktop). It now requires a Claude subscription, not API keys or third-party providers (Bedrock, Vertex, Foundry). * **`hooks.md` (Changes: 1 line)** * *Change:* Updated documentation for `session_crons`. Added `ScheduleWakeup` as a source for scheduled wakeups alongside `CronCreate` and `/loop`. * *Implication:* New hook/feature addition related to scheduling/wakeups. * **`fine-grained-tool-streaming.md` (Changes: Major additions of code examples)** * *Change 1 (Definition):* Changed definition from "character-by-character" to "without server-side JSON buffering". This is a technical clarification. * *Change 2 (Code Examples):* Added massive amounts of code examples in C#, Go, Java, and PHP. Previously only showed Bash, Python, and TypeScript snippets (which were also slightly modified to improve output formatting). * *Implication:* Significant expansion of SDK coverage for "Eager Input Streaming" feature. * **`CHANGELOG.md.md` (Changes: Version 2.1.146)** * *Changes:* * Renamed `/simplify` to `/code-review`. * Auto mode logic change regarding `AskUserQuestion`. * Fix for Windows PowerShell tool (winget/Store path regression). * Fix for MCP pagination bugs. * Fix for Windows Terminal strobing/flickering. * Updater fixes and policy enforcement fixes. * Fixed CLI environment variable forwarding (`CLAUDE_CODE_SUBAGENT_MODEL`). 3. **Synthesize and Structure (in Chinese):** * **Overall Summary:** * Updates focus on refining desktop interaction capabilities (redirection, CLI integration), expanding SDK support for eager input streaming (new languages added), and fixing various bugs in Windows, MCP, and session management. * *Draft (CN):* 本次更新主要集中在优化桌面端交互能力（修正重定向逻辑、CLI 集成限制）、大幅扩展多语言 SDK 对细粒度工具流式传输的支持，以及修复 Windows、MCP 和会话管理中的多项 Bug。 * **Key Themes:** * *Desktop UX Refinement:* Non-blocking redirection and stricter `/desktop` command requirements (subscription only). * *SDK Expansion:* New code examples for C#, Go, Java, and PHP for eager input streaming. * *Bug Fixes & Stability:* Windows-specific fixes (PowerShell, Terminal, junctions), MCP pagination, and environment variable handling. * *Feature Evolution:* `/simplify` -> `/code-review`, new `ScheduleWakeup` hook source. * **Impact Level:** * *Level:* Medium. * *Reasoning:* While mostly fixes and documentation updates, the restriction of the `/desktop` command is a breaking behavior change for API key users. The addition of new SDK examples significantly improves developer experience for those languages, but doesn't break existing code. The `/code-review` rename changes the CLI interface. * **Action Items:** * If you use the `/desktop` command with API keys or third-party providers, note that it is now restricted to Claude subscribers. * Update any scripts or habits using `/simplify`; replace with `/code-review`. * Developers using C#, Go, Java, or PHP should review the new "Eager Input Streaming" examples to reduce latency in tools. * If you are experiencing issues with Windows PowerShell or MCP pagination, update to the latest version (2.1.146). 4. **Final Polish (Markdown formatting):** * Ensure the tone is professional and concise. * Check translations for technical accuracy (e.g., "Eager Input Streaming", "MCP pagination"). * *Refining the Desktop redirect explanation:* The change emphasizes that you can send corrections *while* an action is running, and Claude picks them up *after* the current step, rather than stopping immediately. This is a workflow nuance. * *Refining the Changelog summary:* Mention the PowerShell fix specifically as it was a regression. 5. **Generate Output.** (Proceeding to generate the response based on these steps).

Let me analyze the documentation changes across all 10 pages. The changes fall into several categories: 1. **Platform availability updates for features** - Several features have had their platform availability badges changed: - Batch processing: removed `bedrock` and `vertexAi` from availability - Fine-grained tool streaming: changed from `azureAiBeta` to `azureAi` (promoted from beta) - Prompt caching (1hr): added `bedrock` support 2. **New limitation notes for Bedrock/Vertex AI** - Vision and PDF support pages now have notes that only base64-encoded sources are available on Bedrock and Vertex AI (no URL sources, no Files API) 3. **Bedrock page feature support expansion** - Added detailed "Supported feature highlights" and "Features not supported" sections 4. **Vertex AI page updates** - Added "Supported feature highlights" and "Features not supported" sections, added "Data retention" section, clarified API differences wording 5. **Batch processing** - Changed "is not available" to "is not currently available" for Bedrock/Vertex/Foundry (softening the language) 6. **Web fetch tool** - Changed "not available" to "not currently available" for Bedrock/Vertex AI 7. **Microsoft Foundry** - Simplified the "Features not supported" list by removing endpoint paths 8. **Prompt caching (1hr)** - Added Bedrock support (previously noted as not supported) Key themes: - Platform availability alignment and correction across multiple features - Explicit documentation of Bedrock and Vertex AI limitations (URL sources, Files API not supported) - Feature support clarity for cloud platforms - Language softening ("not available" → "not currently available") suggesting future support may come

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** 3 pages of diffs (`checkpointing.md`, `interactive-mode.md`, `plugin-marketplaces.md`). * **Output Format:** Markdown, concise, insightful, Chinese. * **Structure:** Overall Summary, Key Themes, Impact Level, Action Items. 2. **Analyze the Diffs:** * **Page 1: `checkpointing.md`** * *Change:* Updated instructions for the `/rewind` command and `Esc` + `Esc` behavior. * *Detail:* Previously, `Esc` + `Esc` just opened the menu. Now, behavior depends on input state. * *Logic:* If input has text -> Clears text (saves to history). If input is empty -> Opens rewind menu. Added a `<Note>` box explaining this specific UX interaction. * **Page 2: `interactive-mode.md`** * *Change:* Updated keyboard shortcut table. * *Detail 1 (`Ctrl+C`):* Clarified behavior: interrupts running op OR clears input. Second press exits. * *Detail 2 (`Esc` + `Esc`):* Updated description to match `checkpointing.md`. "Clear input draft, or rewind". Added the same logic: text present -> clear (save to history); empty -> open menu. * **Page 3: `plugin-marketplaces.md`** * *Change:* Updated documentation for the `plugin validate` command. * *Detail:* Clarified scope of validation. * *Logic:* Running against *marketplace* directory -> checks `marketplace.json` (schema, dupes, paths, versions). Running against *plugin* directory -> checks specific plugin files (JSON, YAML frontmatter, hooks). * *Table Update:* Updated error descriptions to specify when they are reported (e.g., "Reported only when validating a plugin directory"). 3. **Synthesize Findings:** * *Overall Theme:* Improved precision and clarity regarding user input handling (shortcuts) and validation tools. * *Common Thread:* Context-sensitive behavior (shortcuts changing based on state) and tool scope (validation changing based on directory). 4. **Draft the Analysis (Internal Draft - English):** * *Summary:* The update refines keyboard shortcuts for input clearing/rewinding based on context and clarifies the scope of plugin validation commands. * *Key Themes:* * Context-sensitive UI: `Esc`+`Esc` and `Ctrl+C` now behave differently depending on whether text is in the input field. * State preservation: Cleared text is saved to history so users don't lose it. * Tool precision: `plugin validate` distinguishes between marketplace-level checks and plugin-level checks. * *Impact:* Low. These are UX improvements and clarifications, not breaking changes to API or core logic. * *Action Items:* * Be aware that double `Esc` clears input if not empty, rather than always opening the menu. * Use `plugin validate` on specific plugin directories to check YAML/frontmatter, not just the marketplace root. 5. **Translate and Refine into Chinese:** * *Summary:* 本次更新主要优化了键盘快捷键的行为逻辑（区分输入状态），并明确了插件验证命令的具体适用范围。 * *Key Themes:* * 上下文感知交互：`Esc`+`Esc` 和 `Ctrl+C` 现在会根据输入框是否包含文本表现出不同的行为。 * 数据防丢失：清除输入时自动保存到历史记录。 * 工具校验细化：`plugin validate` 现在区分了 Marketplace 根目录校验和具体插件目录校验的范围。 * *Impact Level:* Low. (Reason: UX improvements, documentation clarifications, no breaking changes to API or config). * *Action Items:* * 注意快捷键变化：当输入框有内容时，双击 `Esc` 会清除内容而非打开回溯菜单。 * 调整插件调试习惯：若需检查 Skill/Agent 的 YAML frontmatter，需对插件子目录运行验证命令，而非 Marketplace 根目录。 6. **Final Polish (Markdown formatting):** * Ensure the tone is professional and "world-class". * Check against the constraints (concise, max 5 action items). 7. **Final Output Generation** (matches the provided thought process).

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** 10 documentation pages with diffs (Markdown format). * **Task:** Summarize changes and why they matter to developers. * **Output Format:** Markdown (Specifically: Summary, Key Themes, Impact Level, Action Items). * **Language:** Chinese (per instruction "请用中文回复"). 2. **Analyze the Diffs (Page by Page):** * `cli-reference.md`: Minor changes (+28/-28). It looks like formatting or table row updates. The diff shows the table definition, likely reordering or slight wording tweaks in descriptions, but the core commands remain. *Wait, looking closer at the context provided in the snippet:* The snippet ends abruptly at `--permission-mode`, `--mo`. It suggests a table update. Let's re-read carefully. Ah, the snippet provided in the prompt for `cli-reference.md` is truncated. It shows a table structure. The changes seem to be mostly formatting or wording adjustments within the table, as the +/- count is identical (+28/-28). This implies a rewrite or reformatting of the table content rather than adding new features. I'll treat it as a cleanup/refinement. * `discover-plugins.md`: Enhancements (+5/-2). * *Change:* Added "Will install" section in plugin details (v2.1.145+) listing commands, agents, skills, etc. * *Change:* Clarified text about checking plugin details vs homepage. * *Impact:* Users can see what a plugin installs before committing. * `hooks.md`: Major Enhancements (+39/-3). * *Change:* Added `background_tasks` and `session_crons` arrays to `SubagentStop` hooks (v2.1.145). * *Change:* Added `background_tasks` and `session_crons` arrays to `Stop` hooks (v2.1.145). * *Detail:* These arrays help hooks distinguish "done" from "paused for background work". * *Schema:* Detailed table definitions for these arrays (fields like `id`, `type`, `status`, `description`, etc.). * *Impact:* Hook authors can make more intelligent decisions about whether to block or continue based on active background tasks. * `interactive-mode.md`: UI/UX fix (+1/-2). * *Change:* Clarified behavior of the PR badge. It disappears when merged/closed. * *Change:* Status refresh timing (every 60s + immediate after `gh pr` or `git push`). * *Impact:* Better clarity on PR status behavior. * `monitoring-usage.md`: Observability update (+11/-9). * *Change:* Added `agent_id` and `parent_agent_id` attributes to `claude_code.tool` span. * *Impact:* Better tracing of which agent/subagent ran a tool. * `output-styles.md`: Documentation clarification (+2/-2). * *Change:* Clarified "Proactive" style is stronger than "auto mode". * *Impact:* Better understanding of configuration nuances. * `plugins-reference.md`: Validation enhancement (+17/-0). * *Change:* Added section on "Unrecognized fields". Claude ignores unknown fields in `plugin.json` (making it dual-use with VS Code/npm manifests). * *Change:* `claude plugin validate` reports unknown fields as warnings, not errors. * *Change:* Added `--strict` flag for CI to treat warnings as errors. * *Impact:* Easier plugin dev across ecosystems, better CI practices. * `skills.md` (and `slash-commands.md`, identical content): New feature (+11/-0). * *Change:* Introduced `/run`, `/verify`, and `/run-skill-generator` bundled skills (v2.1.145). * *Detail:* `/run` drives the app, `/verify` builds/verifies against the app. `/run-skill-generator` records the recipe. * *Change:* Clarified inline command substitution logic (must be at start of line or after whitespace). * *Impact:* New workflow for running and testing applications. Fix to substitution edge cases. * `statusline.md`: Observability update (+14/-1). * *Change:* Added `workspace.repo.*` fields (host, owner, name) parsed from `origin` remote. * *Change:* Added `pr.*` fields (number, url, review_state) mirroring the PR badge. * *Impact:* Richer statusline customization and git context awareness. 3. **Synthesize and Structure:** * **Overall Summary:** Version 2.1.145 brings significant enhancements to hooks (background task awareness), new bundled skills for app running/verification (`/run`, `/verify`), and richer observability in monitoring and status bars. * **Key Themes:** * *Hooks & Automation:* Hooks now see background tasks/crons to better manage state. * *App Workflow:* New `/run` and `/verify` skills replace simple inference with recordable "recipes". * *Observability:* Tool spans include agent IDs; status line gets repo and PR details. * *Plugin Ecosystem:* Better validation (`--strict`) and tolerance for cross-platform manifests. * *Docs Polish:* Clarifications on PR status, output styles, and command substitution. * **Impact Level:** **Medium**. New features (skills, hook inputs) are additive. No breaking changes indicated. * **Action Items:** * Plugin authors: Update hook logic to utilize `background_tasks` to prevent premature exits. * Devs: Try `/run-skill-generator` to standardize app launches. * Plugin maintainers: Run `claude plugin validate --strict` in CI. * Observability: Update OTEL dashboards to use new `agent_id` fields. 4. **Translate and Refine (Chinese):** * *Summary:* 版本 2.1.145 带来了多项重要更新，包括增强了 Hooks 对后台任务的感知能力，新增了用于运行和验证应用的内置 Skills（`/run`, `/verify`），并显著提升了监控和状态栏的元数据丰富度。 * *Themes:* * **Hooks 增强**: Hooks 现在可以接收 `background_tasks` 和 `session_crons` 数组，以便更智能地判断会话状态。 * **应用运行工作流**: 新增 `/run` 和 `/verify` skills，配合 `/run-skill-generator` 可记录项目特定的启动配方。 * **可观测性**: 工具调用追踪增加 `agent_id`，状态栏增加仓库和 PR 详情。 * **插件生态**: `plugin.json` 容错性提高（忽略未知字段），验证工具新增 `--strict` 模式。 * **文档修正**: 澄清了 PR 状态行为、输出样式差异及命令替换的边缘情况。 * *Impact:* Medium (中等). 主要是功能增强和文档完善，无破坏性变更。 * *Action Items:* * 插件开发者：更新 Hook 逻辑以利用新的 `background_tasks` 数据，避免在后台任务运行时意外退出。 * 开发者：尝试使用 `/run-skill-generator` 来标准化应用的启动流程。 * 插件维护者：在 CI 流程中引入 `claude plugin validate --strict`。 * 运维/监控：更新 OTEL 仪表板以利用新的 `agent_id` 和 `parent_agent_id` 字段追踪工具调用来源。 5. **Final Review against Constraints:** * Concise? Yes. * Insightful? Yes, identified the specific v2.1.145 features. * Markdown format? Yes. * Focus on developers? Yes (hooks, skills, CI). * Chinese language? Yes. *Self-Correction on `cli-reference.md`:* Since the diff was cut off and appeared to be a wash (+28/-28) in a table, I will mention it briefly as a cleanup/reformatting or simply omit if it adds no developer value compared to the other substantial changes. Given the prompt says "Focus on what matters", the table formatting is likely less important than the new hook inputs or skills. I'll omit specific mention of it in the summary to keep it concise, as it looks like a documentation refactor rather than a functional change. *Refining Action Items:* Make them actionable. 1. Update Hooks. 2. Try new Skills. 3. CI Validation. 4. Monitoring Dashboards. (This looks good). 6. **Construct Final Output.** (Proceed to generate response).
