## Overall Summary
本次文档更新明确了插件内 MCP 工具的引用命名格式，优化了 CLI 命令的分类展示，并发布了 v2.1.174 版本修复了 GovCloud 区域、环境变量继承及模型选择器等关键问题。
## Key Themes
* **MCP 工具命名规范化**：确立了 `mcp__plugin_<plugin-name>_<server-name>__<tool-name>` 的命名标准，解决了开发者在权限配置和技能调用时的引用歧义。
* **文档分类清晰化**：将命令明确区分为用于终端的“Shell 命令”和用于应用内的“Session 命令”，降低了新手上手难度。
* **功能稳定性修复**：重点修复了 Bedrock GovCloud 区域能力错误、后台会话环境变量隔离、模型选择器显示逻辑以及技能热重载的性能问题。
## Impact Level
**Medium (中等)**
虽然没有破坏性变更，但 MCP 命名规范的明确对开发者正确配置工具至关重要，而 GovCloud 和环境变量的修复显著改善了企业级用户及高级开发者的使用体验。
## Action Items for Developers
1. **更新配置**：如果你在权限规则或 Skills 中引用了插件捆绑的 MCP 工具，请立即更新为新的完整命名格式（例如 `mcp__plugin_my-plugin_database-tools__query`）。
2. **升级版本**：升级到 v2.1.174 版本，特别是使用 AWS GovCloud 或依赖后台会话环境变量（`ANTHROPIC_*`）的开发者。
3. **查阅命令文档**：查看新的“Essential commands”章节，区分终端启动参数与会话内操作命令（如 `/clear`）。
4. **检查模型选择**：验证修复后的 `/model` 选择器是否正确显示了你的默认模型解析（特别是 Opus/Sonnet 的区分）。
5. **利用新特性**：如需在 VSCode 中查看详细的 24/7 天使用情况细分（包括 Cache misses, Subagents 等），请使用 `/usage` 命令。
💭 Model Reasoning
1. **Analyze the Request:**
* **Role:** World-class programmer analyzing documentation changes.
* **Input:** Three pages of diffs (`mcp.md`, `quickstart.md`, `CHANGELOG.md.md`).
* **Output Format:** Markdown, single batch analysis, specific sections (Summary, Key Themes, Impact, Action Items).
* **Language:** Chinese.
* **Focus:** Developer relevance.
2. **Analyze Page 1: `mcp.md`**
* **Change:** Added a section explaining the naming convention for MCP tools bundled in plugins.
* **Specifics:**
* Format: `mcp__plugin_<plugin-name>_<server-name>__<tool-name>`.
* Sanitization: Non-alphanumeric/underscore/dash characters become `_`.
* Example: `mcp__plugin_my-plugin_database-tools__query`.
* Context: Used in permission rules, skills' `allowed-tools`, or subagents.
* **Developer Implication:** Crucial for anyone configuring permissions, skills, or subagents using plugin-bundled MCP tools. This resolves ambiguity about how to reference these specific tools.
3. **Analyze Page 2: `quickstart.md`**
* **Change 1:** Added multiple `theme={null}` attributes to code blocks. This looks like a build artifact or formatting fix rather than a content change for the user.
* **Change 2:** Reorganized the "Essential commands" section.
* Split into "Shell commands" (terminal) vs. "Session commands" (inside Claude Code).
* Moved `/clear`, `/help`, `/exit` to "Session commands".
* Updated "See the [CLI reference]" to point to specific references for shell vs. session commands.
* **Developer Implication:** Better clarity on where to run specific commands. The `theme={null}` stuff is noise/infrastructure.
4. **Analyze Page 3: `CHANGELOG.md.md`**
* **Change:** Added version 2.1.174 changelog.
* **Key Points:**
* *Feature:* `wheelScrollAccelerationEnabled` setting.
* *Fixes:* Model picker fixes (showing Opus/Sonnet correctly), GovCloud region fixes, background session env variable inheritance, git commit attribution, skill hot-reload performance, attribution headers, and VSCode usage attribution details.
* **Developer Implication:** The GovCloud fix and background session env inheritance are high-value fixes for enterprise/power users. The model picker fixes affect daily usage. The skill hot-reload fix improves developer experience (DX) when building skills.
5. **Synthesize the Analysis:**
* **Overall Summary:** The update primarily focuses on clarifying the naming conventions for plugin-bundled MCP tools, reorganizing the command structure for better clarity, and releasing version 2.1.174 which includes critical bug fixes (GovCloud, environment inheritance) and UI improvements.
* **Key Themes:**
* *MCP & Plugin Interop:* Explicit naming conventions for tool access.
* *UX/Documentation clarity:* Distinguishing between Shell and Session commands.
* *Stability & Fixes:* Addressing edge cases in GovCloud, environment variables, and model selection.
* **Impact Level:** Medium. (Nothing is "breaking" in the traditional sense, but the MCP naming convention is essential for configuration to work, and the GovCloud fix is critical for specific users).
* **Action Items:**
* Update permission/skill configs to use the new MCP tool naming format (`mcp__plugin_...`).
* Review the "Essential commands" section to understand the Shell vs. Session distinction.
* Upgrade to 2.1.174 if using GovCloud or background sessions with custom env vars.
6. **Draft the Response (in Chinese):**
* *Summary:* 本次更新明确了插件捆绑 MCP 工具的命名规范，重构了快速入门中的命令结构，并发布了 v2.1.174 版本修复了多项关键问题。
* *Themes:*
* MCP 集成规范化：明确插件工具的命名规则。
* 文档结构优化：区分 Shell 命令与 Session 命令。
* 稳定性提升：修复 GovCloud、环境变量继承及模型选择器问题。
* *Impact:* Medium (中等)。
* *Action Items:*
* 更新权限或技能配置中的 MCP 工具名称。
* 升级至 v2.1.174 以获取 GovCloud 和环境变量修复。
* 查阅新的命令分类表。
7. **Refine Content:**
* The `theme={null}` changes in `quickstart.md` are technical noise, I will ignore them in the summary but acknowledge the command reorganization.
* Emphasize the MCP naming format because it allows developers to actually *use* these tools in code/config.
8. **Final Output Generation (matching the requested markdown structure):**
* Translate thoughts to the specific format requested.
* *Drafting Chinese text:*
* Summary: 本次文档更新明确了插件内 MCP 工具的引用命名格式，优化了 CLI 命令的分类展示，并发布了 v2.1.174 版本修复了 GovCloud 区域、环境变量继承及模型选择器等关键问题。
