更新提交git skill

PDF 阅读器在慢速双指缩放、竖向滚动页高异步更新、页面请求超时和绘画橡皮擦等场景中，存在视口跳动、迟到结果被错误丢弃、缓存边界不明确及笔迹显示与持久化不同步的问题；同一本书的标注读取和并发写入也会产生不必要的磁盘访问或覆盖风险。\n\n调整缩放 inset 计算和竖向阅读锚点恢复，避免缩放变换被重复计入、真实页高到达时改变当前阅读位置。页面请求改为带 token 的超时重试机制，可在缓存窗口内接收有效迟到结果并提供失败重试入口；页面大图、OCR、笔迹和描述缓存统一按当前页前后两页收敛，PDF 标识改为完整内容 SHA-256，避免同名或相近文件复用错误阅读状态。\n\n绘画会话内按路径实时重绘，退出会话后使用按图层派生的位图缓存，确保橡皮擦即时作用于已提交笔迹；同时为笔迹持久化增加版本控制、为标注读写增加同步保护和内存快照，降低复用与并发场景下的状态错乱。\n\n将项目技能统一迁入 .agents/skills，并以 .claude/skills 相对软链接供 Claude Code 读取；新增详细 Git 提交技能，自动审查改动、生成中文提交说明并约束安全推送。

验证：所有项目技能通过 quick_validate；执行 xcodebuild -workspace ReadViewDemo/ReadViewDemo.xcworkspace -scheme ReadViewDemo -configuration Debug -sdk iphonesimulator CODE_SIGNING_ALLOWED=NO build，构建成功。

+description: 审查当前 Git 工作区，安全选择本次任务文件，生成包含问题背景、根因和修改方案的详细中文提交说明，并提交及按用户要求推送到 Git 服务器。默认不执行构建或测试；用户要求“提交代码”“提交并推送”“同步到 Git”“上传当前修改”或要求生成详细 commit message 时使用。
+---
+
+# 提交 Git 改动
+
+## 目标
+
+在不混入无关修改、不泄露敏感信息、不改写远端历史的前提下，完成“审查—暂存—提交—推送—确认”闭环，并用提交说明解释为什么修改以及如何解决，而不只是罗列文件。
+
+## 工作流
+
+1. 读取仓库级 `AGENTS.md`、当前分支、远端和工作区状态。
+2. 检查暂存与未暂存差异：
+   - 使用 `git status --short` 确认全部改动。
+   - 使用 `git diff` 和 `git diff --cached` 理解真实行为变化。
+   - 必要时查看相关源码和测试，不能仅依据文件名编写提交说明。
+3. 划定本次提交范围：
+   - 只纳入当前用户任务直接相关的文件。
+   - 保留用户已有或其他任务产生的无关修改。
+   - 优先显式 `git add <path...>`；仅在确认所有改动均属本次提交时使用 `git add -A`。
+   - 发现密钥、令牌、证书、个人配置、大型生成物或疑似敏感数据时停止提交并说明。
+4. 不默认执行构建、测试或项目级验证；仅在用户明确要求时执行。
+5. 暂存后再次检查：
+   - 执行 `git diff --cached --check`。
+   - 执行 `git diff --cached --stat` 和 `git diff --cached`。
+   - 确认暂存区没有无关文件、调试残留和意外格式变化。
+6. 编写详细中文提交说明并创建提交。
+7. 用户要求提交到服务器或同步远端时推送：
+   - 有 upstream 时推送当前分支。
+   - 没有 upstream 且远端、目标分支明确时，使用 `git push -u <remote> <branch>`。
+   - 远端或目标分支不明确时先询问，不猜测。
+   - 禁止 force push；除非用户明确要求且风险已说明。
+8. 提交后确认提交哈希、提交标题、当前分支、推送结果和剩余未提交改动。
+
+## 提交说明规范
+
+提交说明使用“标题 + 空行 + 详细正文”的结构。
+
+### 标题
+
+- 用一句中文概括用户可感知的问题和修复结果。
+- 优先写清触发条件、异常表现和结果，例如：
+  `修复无训练点普通课程完成后重进播放页回退为未完成`
+- 使用明确动词，如“修复”“新增”“调整”“重构”“移除”。
+- 不使用“修改代码”“优化问题”“更新若干内容”等空泛描述。
+- 保持单行，不以句号结尾，不添加无依据的工单号或模块前缀。
+
+### 正文
+
+用完整段落解释以下内容：
+
+1. **问题背景与影响**：什么场景触发、用户看到什么、影响哪些路径。
+2. **根因**：原有数据流、状态条件或实现约束为什么导致问题。
+3. **修改方案**：关键行为如何改变，为什么选择该方案，必要时说明兼容和边界处理。
+
+正文应描述行为和因果关系，不要把 `git diff --stat` 改写成文件清单。多个紧密相关的修改可以分段说明，但不要堆砌逐文件 bullet。
+
+若用户明确要求并实际执行了构建、测试或其他验证，可以在正文末尾如实补充；未执行时不需要添加“验证：未执行”之类的说明。
+
+### 示例
+
+```text
+修复无训练点普通课程完成后重进播放页回退为未完成
+
+课件完成态本地记录的保存不区分训练点，但读取端仅在存在
+trainPointModel 时才创建合并器，导致班级、训练和项目均为空的普通课程
+重进播放页后无法读取本地完成记录。
+
+改为始终创建完成态合并器：无训练点时使用空维度合并；由于该场景没有
+服务端完成态可供对账，将本地记录作为唯一持久来源并跳过超期回收，保持
+重新进入播放页后的完成状态稳定。
+
+```
+
+根据真实改动改写示例内容，禁止照抄未发生的场景或验证结论。
+
+## 提交与推送约束
+
+- 不使用 `git reset --hard`、`git checkout --`、`git clean` 等破坏性命令处理工作区。
+- 不使用 `--amend`、rebase、历史改写或强制推送，除非用户明确授权。
+- 不跳过 hooks；hook 失败时先分析原因，不使用 `--no-verify` 绕过。
+- 提交失败后保留暂存区，修复可控问题并重试；不要重复创建等价提交。
+- 推送被拒绝时先获取并解释分支差异，不自动合并、变基或覆盖远端。
+- 若没有可提交差异，直接说明，不创建空提交。
+
+## 交付
+
+报告提交哈希和标题、推送的远端分支，以及仍留在工作区的未提交修改。若只完成本地提交而未推送，必须明确说明。

-
-# Discuss SDK Feature Solution
-
-## Purpose
-
-面向 ReadViewSDK 的"实现方案讨论入口" skill。
-用于在正式开发前，先把需求、约束、可选实现路径和关键取舍聊透；若方案已经确定，则只围绕已选方案继续细化，再交接给开发 skill 进入实现。
-
-该 skill 借鉴 spec-driven 工作流思想：讨论阶段专门捕获灰区决策，计划阶段必须经过代码 / 文档事实核验，最终输出能直接喂给开发 skill 的结构化方案文档，避免"聊完还是不能开发"。
-
-该 skill 的职责固定为：
-- 先理解需求与约束
-- 捕获灰区问题和实现假设
-- 用现有代码 / 文档核验方案可行性
-- 未定方案时：输出 2-4 个可行实现方案，并做对比
-- 已定方案时：只围绕确认方案展开实现讨论，不再继续扩展其他方案
-- 最后给出交接到开发 skill 的明确指令
-- 最终必须产出一份可直接供开发 skill 使用的开发详细文档，或一段可直接执行的开发详细描述
-
-## Core Discussion Rules
-
-- Rule 1 — Think Before Coding
-  - 在提出方案前先核对代码和文档事实，不静默假设
-  - 必须显式写出关键假设、主要取舍和已知风险
-  - 遇到会改变实现路径的关键灰区，先提出并请求确认，不靠猜测补完整个方案
-  - 若存在更简单且满足目标的实现路径，必须主动指出并优先推荐
-- Rule 2 — Simplicity First
-  - 推荐方案优先选择最小可落地路径，而不是概念上更"完整"的设计
-  - 不为了未来可能性预埋推测性扩展，不为单次使用引入抽象
-  - 若某个方案明显过度设计，必须直接指出并解释为什么不推荐
-- Rule 3 — Surgical Changes
-  - 方案只覆盖完成当前目标所必需的改动面
-  - 不把无关重构、顺手统一风格或额外治理动作夹带进推荐方案
-  - 若确有相邻改动依赖，必须明确标注"必要改动"与"可选优化"的边界
-- Rule 4 — Goal-Driven Execution
-  - 讨论输出必须先定义成功标准和验证方式，再给实现交接建议
-  - 不把讨论步骤本身当结果，重点是产出可执行、可验证的方案
-  - 交接给开发 skill 时，必须让对方清楚"做到什么算完成"
-
-## When To Use
-
-当用户提出以下类型需求时使用：
-- "先讨论一下这个需求怎么实现"
-- "这个功能可能有多种实现方式，先分析方案"
-- "先别写代码，先帮我想实现路径"
-- "先比较几种方案，再决定怎么做"
-
-适用场景：
-- 同一个需求可以通过多种技术路径实现
-- 需要权衡 SDK 分层（EPUBCore / EPUBTextRendering / RDReaderView / EPUBUI）、复用、维护成本、回归影响
-- 需要在实现前先明确推荐方案和待确认细节
-- 已经明确采用某个方案，但还需要继续细化实现边界、拆解落地路径和交接开发
-
-不适用场景：
-- 用户已经明确要直接实现，且实现路径基本单一时，优先使用开发类 skill
-- 用户只想生成文档，不需要方案讨论时，优先使用文档类 skill
-
-## Inputs
-
-推荐输入：
-- 需求描述

-- 已知约束（兼容性、性能、API 兼容、CocoaPods 发布等）
-- 已有备选方案（如有）
-- 已确认方案（如已决定）
-- 是否需要推荐方案
-- 是否需要最终落方案文档
-

-
-## Scope / Required Context
-
-默认先读：
-1. `Doc/ARCHITECTURE.md` — 四层架构、数据流、分页模式、位置模型、已知限制
-2. `Doc/CODING_STYLE.md` — 命名规范（RD/RDEPUB 前缀）、分层规则、extension 拆分规则、SS→RD 迁移计划
-3. `Doc/EPUB_MAINTENANCE.md` — 文件职责表、DTCoreText 渲染管线、常见排查场景
-
-按需再读：
-- 涉及 EPUB 解析时：`Sources/RDReaderView/EPUBCore/` 下相关文件
-- 涉及文本渲染时：`Sources/RDReaderView/EPUBTextRendering/` 下相关文件
-- 涉及阅读器容器时：`Sources/RDReaderView/RDReaderView.swift` 及同级文件
-- 涉及 UI 层时：`Sources/RDReaderView/EPUBUI/` 下相关文件
-- 涉及遗留代码时：`Sources/RDReaderView/LegacyRDReaderController/` 下相关文件
-- 涉及 JS 桥接时：`Sources/RDReaderView/Resources/epub-bridge.js`
-
-若文档与代码不一致：
-- 以代码事实为准做方案讨论
-- 在推荐方案中指出不一致点和可能影响
-
-方案文档落地目录约束：
-- 讨论型方案文档统一落到 `Doc/FeatureSolution/`（若目录不存在则创建）
-- 不要把方案讨论文档写入其他目录
-
-## SDK-Specific Discussion Rules
-
-讨论时必须考虑的 SDK 特有约束：
-
-- **分层边界**：方案必须明确落在哪一层，不得跨层引入反向依赖（上层依赖下层允许，反之不允许）
-- **Public API 兼容性**：若改动涉及公共接口（`RDReaderView`、`RDReaderDataSource`、`RDURLReaderController`、`RDEPUBReaderController` 等），必须评估对宿主 App 的 breaking change 影响
-- **渲染路径差异**：方案必须考虑三种渲染路径（`webFixedLayout` / `webInteractive` / `textReflowable`）的适用性，不能只覆盖单一路径
-- **CocoaPods 发布影响**：若方案涉及新增依赖、资源文件或模块结构调整，必须评估 podspec 变更
-- **RD 前缀规范**：所有新增类型必须使用 `RD` 前缀，EPUB 相关使用 `RDEPUB` 前缀
-- **Legacy 层边界**：不在 Legacy 层新增功能；若方案涉及 Legacy 代码，必须明确是迁移还是在新层实现
-
-## GSD-Inspired Discussion Rules
-
-讨论阶段要像 `discuss -> plan -> verify` 闭环一样，先捕获决策，再验证计划，而不是直接跳到实现建议。
-
-必须执行：
-- 灰区捕获：先识别布局、接口形态、数据结构、错误态、路由、持久化、兼容性、回归范围等不明确点
-- 事实核验：方案落地前必须用本仓库代码和 `Doc/` 文档确认入口、复用点、约束和风险
-- 假设显式化：不能确认的问题必须写成 `Assumption`，不得藏在方案正文里
-- 阻塞分级：会改变实现路径的问题标记为 `Blocking Decision`，不会改变路径的问题标记为 `Follow-up`
-- 审计留痕：若落方案文档，必须包含"讨论结论 / 关键决策 / 假设 / 非范围 / 验证清单 / 开发交接指令"
-- 计划可执行：最终方案必须足够小，能被开发 skill 直接逐项执行
-
-禁止行为：
-- 不得只输出宽泛建议，必须落到文件、类、方法、数据流或协议层面的执行点
-- 不得在用户已确认方案后继续展开新方案，除非用户明确要求重新比较
-- 不得把未经核验的包、SDK、接口能力写成已确认事实
-- 不得把需要用户拍板的关键决策伪装成默认实现
-
-## Required Workflow
-
-### Phase 1 — 识别需求、范围、约束、现状
-
-- 明确目标价值、影响模块（EPUBCore / EPUBTextRendering / RDReaderView / EPUBUI / Legacy）、In Scope / Out of Scope
-- 识别当前项目里已有的实现模式、相邻能力和复用点
-- 判断这是单层需求还是跨层需求
-- 建立灰区清单，区分 `Blocking Decision` 与 `Follow-up`
-
-### Phase 2 — 判断讨论模式
-
-- 若方案未定：进入"多方案对比模式"
-- 若方案已定：进入"单方案细化模式"
-- 一旦用户已确认方案，后续同一轮讨论默认保持"单方案细化模式"，除非用户明确要求重新打开方案比较
-
-### Phase 3 — Research / Verify：核验代码与文档事实
-
-- 对照当前仓库确认真实入口、调用链、数据模型、复用的 cell / view / handler / controller / protocol
-- 若方案涉及新增文件，必须确认所属目录层级和是否需要更新 podspec 的 source_files
-- 若方案涉及接口或数据字段，必须明确字段来源、空值策略和兼容策略
-- 若方案涉及 JS 桥接，必须确认 epub-bridge.js 的交互契约
-- 若发现文档和代码不一致，必须标注为风险或阻塞项
-- 若核验结果推翻原方案，必须暂停说明，不得继续包装成可执行方案
-
-### Phase 4A — 多方案对比模式：列出多种实现路径
-
-- 至少提出 2 个可行方案，推荐 2-4 个方案
-- 每个方案都要有清晰的实现方向，而不是抽象建议
-- 优先从现有项目模式和复用能力出发
-
-### Phase 4B — 多方案对比模式：比较方案优缺点和影响范围
-
-- 比较每个方案的：
-  - 核心思路
-  - 落在哪一层（EPUBCore / EPUBTextRendering / RDReaderView / EPUBUI）
-  - 适用前提
-  - 优点
-  - 风险 / 成本
-- 对 SDK 分层、Public API、podspec、回归范围的影响
-- 明确哪些差异会真正影响后续实现和维护
-
-### Phase 5A — 多方案对比模式：提出推荐方案，并列出待确认细节
-
-- 必须明确推荐一个默认方案，不能只平铺选项
-- 待确认项只保留真正影响实现的关键决策
-- 默认产物为对话输出；若用户明确要求，再可选落到 `Doc/FeatureSolution/` 下方案文档
-
-### Phase 5B — 单方案细化模式：围绕确认方案展开
-
-- 不再输出"方案 A / 方案 B / 方案 C"式内容
-- 不再补充"其他也可以这样做"的备选实现，除非用户明确要求回到方案比较
-- 只讨论以下内容：
-  - 当前方案的实现拆解（文件 / 类 / 方法 / 协议）
-  - SDK 分层内的模块边界与职责分配
-  - 关键数据流 / 状态流 / 渲染流
-  - 复用点、依赖点、回归点
-  - 对三种渲染路径的覆盖情况
-  - 风险、前提、灰度方式、验证要点
-  - 交接给开发 skill 的实现摘要
-
-### Phase 6 — 输出实现交接建议
-
-- 在方案确认后，明确下一步应交给哪个开发 skill：
-  - 小中型、单层、MVP 优先：轻量开发 skill
-  - 跨层、复杂联调、完整交付：完整开发 skill
-- 无论是否落文档，最终都必须产出开发交接载体，且二选一不能缺失：
-  - 完整开发 skill：产出可直接执行的开发详细文档，默认落到 `Doc/FeatureSolution/`
-  - 轻量开发 skill：产出可直接粘贴执行的开发详细描述，覆盖实现目标、范围、代码落点、关键步骤、验收标准和自测要点
-- 给出可直接粘贴给开发 skill 的实现摘要；若已有更完整的详细文档/描述，则摘要必须引用它而不是只给一句话概括
-- 若落方案文档，必须让开发指令引用该文档的真实路径，并提醒开发 skill 严格按计划执行
-
-## Output Contract
-
-默认输出结构按模式区分：
-
-若方案未定：
-- A. 需求理解
-- B. 灰区问题与实现假设

-  - 若下一步是轻量开发 skill，必须提供开发详细描述正文
-- 已定方案时：
-  - `B. 灰区问题与实现假设` 必须列出阻塞项、假设和后续项
-  - `D. 确认方案拆解` 只能围绕确认方案展开，禁止附带其他方案信息
-  - `E. 实现风险与关键细节` 只讨论该方案落地所需信息
-  - `F. 实现交接建议` 必须明确下一步交给哪个开发 skill，并附带可直接执行的详细文档或详细描述
-
-若用户要求落方案文档，文档必须包含：
-- 需求目标
-- 讨论结论
-- 关键决策
-- 实现假设
-- 非范围
-- SDK 分层落点（文件 / 类 / 方法 / 协议）
-- 数据流 / 状态流 / 渲染流
-- 开发任务清单
-- 验收标准
-- 自测清单
-- 待确认项

-- SDK 分层落点（文件 / 类 / 方法 / 协议）
-- 实现步骤
-- 关键约束与复用点
-- 对三种渲染路径的覆盖说明
-- 验收标准
-- 自测清单
-- 待确认项或实现假设
-
-## Validation
-
-- 本 skill 默认只做方案讨论，不直接进入代码实现
-- 默认不修改仓库文件；只有用户明确要求时，才可选落方案文档到 `Doc/FeatureSolution/`
-- 即使不落方案文档，最终回复也必须包含一份可直接交给开发 skill 使用的详细交接内容，不能只停留在高层方案结论
-- 若本次调用只做讨论或只新增方案文档，可不执行构建验证
-- 若新增或移动方案文档，建议同步更新目录索引
-- 若后续进入代码实现，则由对应开发 skill 负责执行项目默认构建验证（`xcodebuild` 或 CocoaPods 集成验证）
-- 若用户已确认方案，则默认进入单方案细化模式，除非用户明确要求重新比较备选方案
-
-## Maintenance Rules
-
-- 该 skill 的职责是"讨论后交接实现"，不和开发 skill、文档类 skill 重叠
-- 优先复用 `Doc/` 作为知识源，不新增独立 references 体系
-- 方案文档目录固定为 `Doc/FeatureSolution/`
-- 持续保持 `discuss -> research/verify -> plan handoff` 的轻量闭环，避免退化成只聊天不交付的建议列表
-- 若该 skill 的默认输出结构、交接规则或适用边界调整，必须同步更新对应文档
-- SDK 四层架构（EPUBCore → EPUBTextRendering → RDReaderView → EPUBUI）是方案讨论的核心参照框架，任何方案都必须明确标注落点层级

-
-## Core Execution Rules
-
-- Rule 1 — Think Before Coding
-  - 先核对代码和文档事实，不静默假设
-  - 必须显式写出关键假设、主要取舍和已知风险
-  - 遇到会改变实现路径的关键灰区，先暂停确认，不靠猜测继续推进

-- Rule 4 — Goal-Driven Execution
-  - 先定义成功标准，再围绕成功标准实施和验证
-  - 不给自己堆步骤，重点是闭环达到验收结果
-  - 修改后必须验证，未验证通过前不能视为完成
-
-## When To Use
-
-当用户提出以下类型需求时使用：
-- "使用 start-sdk-feature-dev-lite 完成这个功能"
-- 在 ReadViewSDK 中开发单一功能或单层变更
-- 需要修复局部编译错误或行为问题
-- 需要同步更新文档
-- 需要小幅调整 podspec
-
-不适用场景：
-- 需求跨多个 SDK 层级、涉及多阶段联调或需要完整项目级方案时，改用 `start-sdk-feature-dev`
-- 目标是只生成文档而不改业务代码时，优先使用文档类 skill
-- 目标是方案讨论而不进入实现时，优先使用 `discuss-sdk-feature-solution`
-
-## Inputs
-
-推荐输入：
-- 功能名称
-- 目标 / 用户价值
-- 范围（In Scope）
-- 非范围（Out of Scope）
-- 目标层级（EPUBCore / EPUBTextRendering / RDReaderView / EPUBUI）
-- 详细需求
-- 验收标准
-- 约束（兼容性 / 性能 / 禁止新增依赖 / 指定渲染路径）
-
-若信息不足：
-- 先基于代码和文档补齐可发现事实
-- 再列最多 5 条关键假设
-- 基于假设继续推进 MVP，并在交付中标注待确认项
-
-## Scope / Required Context
-
-仅针对 ReadViewSDK 现有架构执行。
-
-SDK 四层架构参照：
-- Layer 1 — EPUBCore（`Sources/RDReaderView/EPUBCore/`）：EPUB 解析引擎
-- Layer 2 — EPUBTextRendering（`Sources/RDReaderView/EPUBTextRendering/`）：文本渲染路径
-- Layer 3 — RDReaderView（`Sources/RDReaderView/` 根目录）：分页阅读器容器
-- Layer 4 — EPUBUI（`Sources/RDReaderView/EPUBUI/`）：开箱即用 UI
-- Legacy（`Sources/RDReaderView/LegacyRDReaderController/`）：遗留代码，不在其上新增功能
-
-分层依赖规则（上→下允许，下→上禁止）：
-- EPUBUI → RDReaderView → EPUBTextRendering → EPUBCore
-
-默认先读：
-1. `Doc/ARCHITECTURE.md` — 四层架构、数据流、分页模式、位置模型
-2. `Doc/CODING_STYLE.md` — 命名规范、分层规则、extension 拆分规则
-3. `Doc/EPUB_MAINTENANCE.md` — 文件职责表、渲染管线、排查场景
-
-按需再读：
-- `Doc/FeatureSolution/*.md`（若有方案文档）
-- 涉及哪一层就读该层目录下的相关源码
-- 涉及 JS 桥接时：`Sources/RDReaderView/Resources/epub-bridge.js`
-- 涉及 podspec 时：`RDReaderView.podspec`
-
-若文档与代码不一致：
-- 以代码事实为准完成本次实现
-- 在交付中标注不一致点，并指出建议更新的文档
-
-## Required Workflow
-
-### Phase 1 — 识别需求和范围
-
-- 明确目标价值、影响层级（EPUBCore / EPUBTextRendering / RDReaderView / EPUBUI）、In Scope / Out of Scope
-- 优先做最小可落地实现，不做需求外重构
-- 若需求信息不足，先通过仓库事实补齐，再基于假设推进
-
-### Phase 2 — 按需读取 Doc 与代码事实
-
-- 先读默认 Doc（ARCHITECTURE / CODING_STYLE / EPUB_MAINTENANCE）
-- 根据需求类型补读对应层级的源码
-- 用源码确认真实入口、调用链和复用点，不只依赖文档
-
-### Phase 3 — 形成最小实现方案
-
-- 保持分层边界：
-  - EPUB 解析逻辑在 EPUBCore
-  - 文本渲染逻辑在 EPUBTextRendering
-  - 分页容器逻辑在 RDReaderView
-  - 开箱即用 UI 在 EPUBUI
-  - 不在 Legacy 层新增功能
-- 命名、注释、日志风格遵循 `Doc/CODING_STYLE.md`
-- Swift / iOS 默认规则：
-  - 新增 Swift 类型遵循 `RD` / `RDEPUB` 前缀和层级目录归属
-  - 避免新增强制解包；确需使用时必须先收敛前置条件
-  - 不为"现代化"而重写稳定代码；仅在本次需求明确受益时再迁移系统 API
-  - 当前项目默认保持 UIKit + Auto Layout + 既有组件风格，SDK 层不使用 SnapKit
-  - 注释和日志使用中文
-  - Debug 输出放在 `#if DEBUG` 守卫下
-  - 不在日志中输出敏感信息
-- 异步闭包默认 `[weak self]`，UI 更新回到主线程
-- 通知 / 定时器 / 回调在生命周期结束时必须清理
-- 数据模型用 `struct` + `Codable` + `Equatable`，服务对象用 `final class`
-- 可见性按最小原则：`private` > `fileprivate` > `internal` > `public`
-- 错误使用 `enum` + `LocalizedError`，禁止 force unwrap
-- 单文件若预计超过 600 行，需主动拆分扩展文件
-
-### Phase 4 — 执行修改与文档同步
-
-- 所有代码改动遵循最小改动原则
-- 修改代码时必须补充必要注释，重点说明关键逻辑、边界条件和不直观处理；不要省略应有注释，也不要添加无信息量的描述性注释
-- 默认补做轻量 SDK 自检：
-  - 新增类型是否使用正确前缀和层级归属
-  - 本次改动涉及的渲染路径是否正常工作
-  - Public API 是否有意外 breaking change
-  - podspec 是否需要更新（新增文件时）
-  - 生命周期、通知/定时器/回调清理是否完整
-  - 异步闭包是否考虑 `[weak self]`
-- 修改代码后必须同步更新受影响文档，不能只停留在代码实现
-- 若本次改动涉及 EPUB 维护相关，必须回写 `Doc/EPUB_MAINTENANCE.md`
-- 若本次是方案讨论文档交接落地，方案类文档统一放到 `Doc/FeatureSolution/`
-- 若新增、重命名或移动文档，必须同步更新目录索引
-
-### Phase 5 — 构建验证与交付
-
-- 完成修改后，按项目默认命令执行编译验证
-- 若出现编译错误，自动修复并重编译
-- 若遇构建锁问题，自动重试
-- 交付时固定输出：
-  - A. 需求理解
-  - B. 开发计划
-  - C. 开发实施
-  - D. 验证结果
-  - E. 交付摘要
-
-## Output Contract
-
-最终回复必须完整输出以下 5 个板块，标题保持一致：
-- A. 需求理解
-- B. 开发计划
-- C. 开发实施
-- D. 验证结果
-- E. 交付摘要
-
-各板块内容要求：
-- A：3-6 条，覆盖目标价值、范围、目标层级、限制
-- B：按"方案对齐 / MVP 实现 / 验证与交付"三阶段组织
-- C：描述实际改动、关键实现取舍，以及本次补充了哪些关键代码注释
-- D：给出构建结果、关键路径验证、未覆盖风险
-- E：列出改动文件、关键取舍、已同步文档与具体文档落点、后续建议
-
-## Validation
-
-若本次调用修改了任何 Swift / Objective-C / 工程配置 / podspec 文件，必须执行构建验证。
-
-验证方式：
-- 若 Demo 工程可用：
-  ```bash
-  xcodebuild build -workspace ReadViewSDKDemo/ReadViewSDKDemo.xcworkspace -scheme ReadViewSDKDemo -sdk iphonesimulator -derivedDataPath /private/tmp/readview-sdk-derived
-  ```
-- 若仅有 SDK 源码（无 workspace）：
-  ```bash
-  pod lib lint RDReaderView.podspec --allow-warnings
-  ```
-
-验证规则：
-- 编译失败时必须自行修复并重试
-- 遇到 `database is locked` 等锁问题时自动重试，建议最多 5 次
-- 直到 `BUILD SUCCEEDED` 或 `pod lib lint passed` 才可交付
-- 如果本次仅修改文档或 skill 文件，可跳过构建，但要在交付中明确说明原因
-
-## Maintenance Rules
-
-- 优先复用 `Doc/`，不要把项目级规则复制进多个 skill 造成双份维护
-- 新增项目约束时，优先更新 `Doc/CODING_STYLE.md`、`Doc/ARCHITECTURE.md` 等主文档，再调整 skill
-- 轻量与完整要保持"轻重不同、规则不冲突"，其中完整版应在轻量版闭环基础上扩展跨层与联调要求，而不是另起一套风格
-- 变更默认流程、输出格式或适用场景时，必须同步更新相关文档
-- 本 skill 持续作为默认开发入口，保持"轻量、清晰、可直接执行"
-- SDK 四层架构是执行的核心参照框架，单层改动也必须明确标注落点层级

-- 必须在交付中写明回滚点或回退策略
-
-默认先读：
-1. `Doc/ARCHITECTURE.md` — 四层架构、数据流、分页模式、位置模型、已知限制
-2. `Doc/CODING_STYLE.md` — 命名规范（RD/RDEPUB 前缀）、分层规则、extension 拆分、SS→RD 迁移计划
-3. `Doc/EPUB_MAINTENANCE.md` — 文件职责表、DTCoreText 渲染管线、常见排查场景
-
-按需再读：
-- `Doc/FeatureSolution/*.md`（若有方案文档）
-- 涉及 EPUB 解析时：`Sources/RDReaderView/EPUBCore/` 下相关文件
-- 涉及文本渲染时：`Sources/RDReaderView/EPUBTextRendering/` 下相关文件

-
-## SDK-Specific Execution Rules
-
-### 命名与可见性
-- 所有新增类型必须使用 `RD` 前缀，EPUB 相关使用 `RDEPUB` 前缀
-- 新增类型归属正确层级目录，不得随意放置
-- 可见性按最小原则：`private` > `fileprivate` > `internal` > `public`
-- 数据模型用 `struct` + `Codable` + `Equatable`
-- 服务对象用 `final class`
-
-### 代码组织
-- 单文件超过 600 行需主动拆分 `TypeName+Feature.swift` 扩展文件
-- 大型 Controller 超过 1000 行必须拆分
-- extension 文件承担独立子职责，不只做"行数搬运"
-
-### 内存与并发
-- 异步闭包默认 `[weak self]`
-- UI 更新必须回到主线程
-- 通知 / 定时器 / 回调在 deinit 或生命周期结束时必须清理
-
-### 渲染路径覆盖
-- 新增功能必须评估对三种渲染路径的影响：
-  - `webFixedLayout`：固定版式 EPUB（漫画、绘本）— WKWebView 渲染
-  - `webInteractive`：可重排 + 交互脚本 EPUB — WKWebView 渲染
-  - `textReflowable`：纯文本可重排 EPUB — DTCoreText 渲染
-- 若功能仅适用于部分路径，必须在交付中明确标注适用范围和不适用路径的处理方式
-
-### Public API 兼容性
-- 涉及公共接口（`RDReaderView`、`RDReaderDataSource`、`RDURLReaderController`、`RDEPUBReaderController` 等）的改动，必须评估 breaking change
-- 若存在 breaking change，必须在交付中标注并给出迁移指引
-- 新增 public API 需考虑 Objective-C 互操作（`@objc`、`@objcMembers`）
-
-### CocoaPods 发布影响
-- 新增源文件：确认 podspec `source_files` glob 是否已覆盖
-- 新增资源文件：确认 podspec `resource` / `resource_bundles` 是否已覆盖
-- 新增依赖：确认 podspec `dependency` 是否已声明，评估对宿主 App 的依赖传递影响
-- 模块目录结构调整：必须同步更新 podspec
-
-### JS 桥接
-- 涉及 `epub-bridge.js` 的改动，必须确认 JS ↔ Swift 消息契约的一致性
-- JS 侧新增消息类型时，Swift 侧必须有对应处理分支
-- 修改已有消息类型时，必须评估向后兼容
-
-### 错误处理
-- 使用 `enum` + `LocalizedError` 定义错误类型
-- 禁止 force unwrap（`!`），确需使用时必须先收敛前置条件
-- 关键路径的错误必须向调用方传递，不得静默吞掉
-
-## Required Workflow
-
-### Phase 1 — 识别需求和范围
-
-- 明确目标价值、影响层级（EPUBCore / EPUBTextRendering / RDReaderView / EPUBUI / Legacy）、In Scope / Out of Scope
-- 判断是否涉及跨层、跨渲染路径、跨模块联调
-- 若用户提供开发计划文档，先确认本次执行的唯一计划来源，并提取计划任务清单
-- 优先做计划内最小可落地实现，不做需求外重构
-- 若需求信息不足，先通过仓库事实补齐，再基于假设推进
-
-### Phase 2 — 按需读取 Doc 与代码事实
-
-- 若用户指定开发计划文档，必须先完整读取该文档
-- 先读默认 Doc（ARCHITECTURE / CODING_STYLE / EPUB_MAINTENANCE）
-- 根据需求类型补读各层源码和相关文档
-- 用源码确认真实入口、调用链、数据流、状态流和复用点，不只依赖文档
-
-### Phase 3 — 对齐并锁定开发计划
-
-- 若已有开发计划，必须按计划锁定实现路径，不重新设计方案
-- 若没有开发计划，才允许形成最小可落地方案：先复用现有模式与能力，再考虑新增抽象
-- 保持分层边界：
-  - EPUB 解析逻辑在 EPUBCore
-  - 文本渲染逻辑在 EPUBTextRendering
-  - 分页容器逻辑在 RDReaderView
-  - 开箱即用 UI 在 EPUBUI
-  - 不在 Legacy 层新增功能
-- 命名、注释、日志风格遵循 `Doc/CODING_STYLE.md`
-- Swift / iOS 默认规则：
-  - 新增 Swift 类型遵循 `RD` / `RDEPUB` 前缀和层级目录归属
-  - 避免新增强制解包；确需使用时必须先收敛前置条件
-  - 不为"现代化"而重写稳定代码；仅在本次需求明确受益时再迁移系统 API
-  - 当前项目默认保持 UIKit + Auto Layout + 既有组件风格，SDK 层不使用 SnapKit
-  - 注释和日志使用中文
-  - Debug 输出放在 `#if DEBUG` 守卫下
-  - 不在日志中输出敏感信息
-- 单文件预计超过 600 行需主动拆分，超过 1000 行必须拆分
-- 若为跨层需求，计划中必须写清：
-  - 主改动层级
-  - 被影响层级
-  - 渲染路径覆盖范围
-  - 联调依赖点
-  - 关键风险
-  - 回滚点或降级方式
-- 开始编码前必须形成内部执行清单，清单项必须能追溯到开发计划；计划外项只能标记为"必要补齐"或"待确认"，不能直接实施
-
-### Phase 4 — 执行修改与文档同步
-
-- 所有代码改动遵循计划内最小改动原则
-- 严格按开发计划清单逐项修改；不得临时改换实现方式或增加计划外功能
-- 若执行中需要偏离计划，必须暂停确认，不能先改后说明
-- 修改代码时必须补充必要注释，重点说明关键逻辑、边界条件和不直观处理
-- 默认补做 SDK 自检：
-  - 检查新增类型是否使用正确前缀和层级归属
-  - 检查三种渲染路径的覆盖情况
-  - 检查 Public API 是否有意外 breaking change
-  - 检查 podspec 是否需要更新
-  - 检查 JS 桥接消息契约是否一致
-  - 关键页面或组件检查生命周期、通知/定时器/回调清理是否完整
-  - 新增 UI 检查长文本、图标按钮语义、重要状态是否只靠颜色表达
-  - 异步闭包默认考虑 `[weak self]`，UI 更新回到主线程
-- 修改代码后必须同步更新受影响文档，不能只停留在代码实现
-- 若本次改动涉及 EPUB 维护相关，必须回写 `Doc/EPUB_MAINTENANCE.md`
-- 若本次是方案讨论文档交接落地，方案类文档统一放到 `Doc/FeatureSolution/`
-- 若新增、重命名或移动文档，必须同步更新目录索引
-
-### Phase 5 — 构建验证与交付
-
-- 完成修改后，按项目默认命令执行编译验证
-- 若出现编译错误，自动修复并重编译
-- 若遇构建锁问题，自动重试（建议最多 5 次）
-- 若是跨层需求，除构建外还应补充关键联调路径说明
-- 交付时固定输出：
-  - A. 需求理解
-  - B. 开发计划
-  - C. 开发实施
-  - D. 验证结果
-  - E. 交付摘要
-
-## Output Contract
-
-最终回复必须完整输出以下 5 个固定板块：
-- A. 需求理解
-- B. 开发计划
-- C. 开发实施
-- D. 验证结果
-- E. 交付摘要
-
-各板块内容要求：
-- A：3-8 条，覆盖目标价值、范围、目标层级、渲染路径覆盖、交互流、限制
-- B：按"计划来源 / 计划任务清单 / 执行顺序 / 验证与交付"组织；若有开发计划文档，必须逐条对应计划项
-- C：描述实现过程、复用点、关键取舍，以及本次补充了哪些关键代码注释；若有计划未写明但必须补齐的内容，必须单独标注
-- D：给出编译结果、关键路径验证、自动重试/自动修复情况、未覆盖风险
-- E：列出改动文件、计划符合情况、关键取舍、回滚点或降级方式、已同步文档与具体文档落点、后续建议
-
-## Validation
-
-若本次调用修改了任何 Swift / Objective-C / 工程配置 / podspec 文件，必须执行构建验证。
-
-验证方式：
-- 若 Demo 工程可用：
-  ```bash
-  xcodebuild build -workspace ReadViewSDKDemo/ReadViewSDKDemo.xcworkspace -scheme ReadViewSDKDemo -sdk iphonesimulator -derivedDataPath /private/tmp/readview-sdk-derived
-  ```
-- 若仅有 SDK 源码（无 workspace）：
-  ```bash
-  pod lib lint RDReaderView.podspec --allow-warnings
-  ```
-
-验证规则：
-- 若出现编译错误，必须自动修复并重编译
-- 若遇到 `database is locked` 等构建锁问题，自动重试，建议最多 5 次
-- 直到 `BUILD SUCCEEDED` 或 `pod lib lint passed` 才可进入交付阶段
-- 若本次只改文档或 skill 文件，可跳过编译，但要在交付中明确说明
-
-## Maintenance Rules
-
-- 优先复用 `Doc/`，不要把项目级规则复制进多个 skill 造成双份维护
-- 新增项目约束时，优先更新 `Doc/CODING_STYLE.md`、`Doc/ARCHITECTURE.md` 等主文档，再调整 skill
-- 轻量与完整要保持"轻重不同、规则不冲突"，其中完整版应在轻量版闭环基础上扩展跨层与联调要求，而不是另起一套风格
-- 变更默认流程、输出格式或适用边界时，必须同步更新相关文档
-- 本 skill 持续作为完整开发入口，保持"可执行、可联调、可回滚、可交付"
-- SDK 四层架构（EPUBCore → EPUBTextRendering → RDReaderView → EPUBUI）是执行的核心参照框架，所有改动必须明确标注落点层级和依赖方向

+## 适用范围与语言
+
+- 默认处理当前仓库的 EPUB SDK、PDF SDK、Demo 和测试。
+- 计划、交付说明、`Doc/` 与项目 Markdown 使用中文。
+- 代码标识符、文件名、API 和配置键保持英文；代码注释、Docstring 和提交信息使用中文。
+- 只做当前目标所需的最小改动，保留工作区内与任务无关的未提交修改。
+- 任何写文件的 agent 必须先读取 `CONTEXT.md`。
+
+## 自动选择项目 Skill
+
+根据用户意图选择 `.agents/skills/` 中最匹配的 Skill：
+
+- 先讨论、比较方案、不要改代码：`discuss-sdk-feature-solution`
+- 单模块功能、Bug 修复、UI 调整、局部重构、构建修复：`start-sdk-feature-dev-lite`
+- 跨层/跨阅读器改造、公共 API 或持久化迁移、复杂联调、完整方案执行：`start-sdk-feature-dev`
+- 隐藏问题、并发、生命周期、性能、内存、缓存或兼容性审查：`review-swift-ios-sdk`
+- 全局代码规范：`generate-sdk-code-style-doc`
+- 单模块代码规范：`generate-module-code-style-doc`
+- 模块调用链、状态流、分页或缓存实现逻辑：`generate-module-implementation-logic`
+- 审查改动、生成详细中文提交说明并提交或推送 Git：`commit-git-changes`
+
+不要为简单任务叠加多个 Skill。用户明确指定 Skill 时优先使用；任务边界扩大时再切换或补充，并说明原因。
+
+## 文档按需读取
+
+先定位源码，再读取直接相关文档，不默认全文加载整个 `Doc/`：
+
+| 任务 | 必读资料 |
+| --- | --- |
+| 任意代码修改 | `CONTEXT.md`、`Doc/CONVENTIONS.md` 相关章节 |
+| 分层或跨模块改造 | `Doc/ARCHITECTURE.md` |
+| 公共 API | `Doc/API_REFERENCE.md` 与真实 public 声明 |
+| EPUB 解析/排版/分页/UI | 对应 `Doc/*_CODE_REFERENCE.md` 或专题文档 |
+| PDF 阅读器 | `Sources/RDPDFReaderView` 源码；现有文档不足时以源码为准 |
+| 测试与回归 | `Doc/TESTING.md` |
+| 用户指定方案 | 指定文档，必须完整读取 |
+
+`Doc/index.md` 用于路由。文档与源码冲突时以当前源码为事实，并指出待同步项。
+
+## 模块边界
+
+- EPUB：`EPUBCore` → `EPUBTextRendering` → `ReaderView` → `EPUBUI`，禁止下层反向依赖上层。
+- PDF：通用分页容器位于 `Sources/RDPDFReaderView/ReaderView`，成品能力位于 `Sources/RDPDFReaderView/Sources`。
+- Demo 和 UITests 只承担集成、样例与回归，不承载 SDK 核心业务。
+- 保持 UIKit、SnapKit 和当前 CocoaPods 结构；新增依赖、资源或系统 framework 时同步检查对应 podspec。
+- 新增类型遵循现有 `RD`、`RDEPUB`、`RDPDF` 前缀和最小可见性。
+
+## SDK 兼容与质量
+
+- 修改 public API 前评估宿主源码兼容、默认行为和迁移方式。
+- 修改 Codable、持久化文件、缓存键或 book identifier 时提供版本与失效/迁移策略。
+- UI 更新回主线程；异步任务处理取消、超时、迟到结果、恰好一次完成和生命周期。
+- EPUB 改动检查 `.textReflowable`、`.webInteractive`、`.webFixedLayout` 的影响。
+- PDF 改动检查宿主图片 Provider 与内置 PDFKit Provider 的影响。
+- 滚动、缩放、分页和绘画热点避免同步 IO、重复解码、无界缓存和大对象长期驻留。
+
+## 验证
+
+修改 Swift、工程配置或 podspec 后默认执行：
+
+`xcodebuild -workspace ReadViewDemo/ReadViewDemo.xcworkspace -scheme ReadViewDemo -configuration Debug -sdk iphonesimulator CODE_SIGNING_ALLOWED=NO build`
+
+按风险补充 `Doc/TESTING.md` 中的定向 UI 测试。仅修改文档、规则或 Skill 时可跳过 Xcode 构建，但必须执行结构、引用和格式检查。

+
+## Installation
+
+### CocoaPods
+
+[CocoaPods](http://cocoapods.org) is a dependency manager for Cocoa projects. You can install it with the following command:
+
+```bash
+$ gem install cocoapods
+```
+
+> CocoaPods 1.1.0+ is required to build SnapKit 4.0.0+.
+
+To integrate SnapKit into your Xcode project using CocoaPods, specify it in your `Podfile`:
+
+```ruby
+source 'https://github.com/CocoaPods/Specs.git'
+platform :ios, '10.0'
+use_frameworks!
+
+target '<Your Target Name>' do
+    pod 'SnapKit', '~> 5.7.0'
+end
+```
+
+Then, run the following command:
+
+```bash
+$ pod install
+```
+
+### Carthage
+
+[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
+
+You can install Carthage with [Homebrew](http://brew.sh/) using the following command:
+
+```bash
+$ brew update
+$ brew install carthage
+```
+
+To integrate SnapKit into your Xcode project using Carthage, specify it in your `Cartfile`:
+
+```ogdl
+github "SnapKit/SnapKit" ~> 5.0.0
+```
+
+Run `carthage update` to build the framework and drag the built `SnapKit.framework` into your Xcode project.
+
+### Swift Package Manager
+
+[Swift Package Manager](https://swift.org/package-manager/) is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.
+
+> Xcode 11+ is required to build SnapKit using Swift Package Manager.
+
+To integrate SnapKit into your Xcode project using Swift Package Manager, add it to the dependencies value of your `Package.swift`:
+
+```swift
+dependencies: [
+    .package(url: "https://github.com/SnapKit/SnapKit.git", .upToNextMajor(from: "5.0.1"))
+]
+```
+
+### Manually
+
+If you prefer not to use either of the aforementioned dependency managers, you can integrate SnapKit into your project manually.
+
+---
+
+## Usage
+
+### Quick Start
+
+```swift
+import SnapKit
+
+class MyViewController: UIViewController {
+
+    lazy var box = UIView()
+
+    override func viewDidLoad() {
+        super.viewDidLoad()
+
+        self.view.addSubview(box)
+        box.backgroundColor = .green
+        box.snp.makeConstraints { (make) -> Void in
+           make.width.height.equalTo(50)
+           make.center.equalTo(self.view)
+        }
+    }
+
+}
+```
+
+### Playground
+You can try SnapKit in Playground.
+
+**Note:**
+
+> To try SnapKit in playground, open `SnapKit.xcworkspace` and build SnapKit.framework for any simulator first.
