 # 开发指南

-## 加载边界
+## 先匹配任务与文件

- 遵守已提供的 [AGENTS.md](../../../AGENTS.md)，上下文已有的规则不重复读取
- 下表是条件导航，不是必读清单，只加载当前任务命中的技能与章节，进入新阶段再补读
- 文档链接带 `#章节` 不代表读取工具会自动截取内容，先用 `rg -n '^#{1,4} ' 文件` 找边界，再按范围读取；常规定位不整份加载 CONTRIBUTING、架构、API、主题或全部 references，确需全文审查时再展开
- 每次补读先明确要解决的未知项，已有资料足够就继续工作；文档提及 Rust、Vue、插件或发布，不等于要加载对应开发流程
+按用户要改的行为初判，定位后按实际修改或审查的文件复核，不要求用户说出“前端”“后端”或技能名。**命中多行就同时执行，先读取对应规范再修改或给出审查结论**；任务范围变化时补齐新命中项，已有上下文直接复用

-## 按任务读取
-
-| 当前任务 | 必读的相关部分 |
+| 命中条件，操作或文件满足其一即可 | 必须执行 |
 | --- | --- |
-| 开发、排障、代码审查 | [问题与方案依据](../../../CONTRIBUTING.md#问题与方案依据)，需要定位代码时按 AGENTS 的 CodeGraph 约定执行 |
+| 调整页面、弹窗、表单、按钮、文案、样式或交互；目标在 `frontend/`、`modules/ui/`、插件前端，或是 `.vue` 文件 | [前端流程](references/frontend.md)，覆盖组件复用、文案、Token、样式、视觉状态和运行证据；局部修改同样执行 |
+| 修改服务端接口、路由、调度、账号与用量规则、持久化、后台任务或协议行为；目标是 `backend/` 中的实现、配置、迁移，或 Rust 源码 | [Workspace 边界](../../../docs/architecture.md#3-workspace-边界)、所属模块、[后端自审](../../../docs/architecture.md#后端自审)；涉及 Rust 时使用 `$rust-best-practices` 和下方后端注释要求，验证时读[命令](../../../docs/architecture.md#验证命令) |
+| 修改页面接口调用，或开发、排查、审查面向管理端或模型客户端的 HTTP／WS API 合同 | [API](../../../docs/api.md)对应章节；优先复用已有接口，核对调用方 → 服务端解析 → 实际查询或执行，不能只凭前端类型认定参数生效；按实际改动叠加前后端规范 |
 | 模块或调用链变更 | [Workspace 边界](../../../docs/architecture.md#3-workspace-边界)及所属模块章节，不通读整份架构 |
-| Rust 开发或审查 | `$rust-best-practices`、所属模块、[后端自审](../../../docs/architecture.md#后端自审)，验证时读[命令](../../../docs/architecture.md#验证命令) |

-| 接口、部署或迁移 | 分别定位 [API](../../../docs/api.md)、[部署](../../../deploy/README.md)、[迁移](../../../backend/migrations/README.md)的对应章节 |
-| SDK、Runtime、宿主扩展或独立插件 | [插件职责边界](references/plugin-boundaries.md)；只有创作、排查独立网关插件时使用 [cpr-plugin-dev](../cpr-plugin-dev/SKILL.md) |

 | 修改或审查文档 | [文档检查](references/documentation.md)及目标章节，不默认读取代码开发、页面验收或发布流程 |
 | 普通代码审查 | [审查标准](../../../CONTRIBUTING.md#审查标准)；审查默认只读 |
 | PR / Issue / 发版 | 按当前意图选 [PR](../cpr-github-pr/SKILL.md)、[Issue](../cpr-github-issue/SKILL.md)或[发版](../cpr-release/SKILL.md)，普通提交不创建 PR |

+纯文档任务按文档分支执行，不因文档所在目录或提及的路径、语言、功能加载开发流程。每次补读只解决当前未知项；文档链接带 `#章节` 不代表工具自动截取，先用 `rg -n '^#{1,4} ' 文件` 找边界，只读命中章节，不预读整份 CONTRIBUTING、架构、API、主题或全部 references，全文审查除外
+
 ## 参考仓库的优先级

- 涉及 Codex 行为、协议或兼容性时，以官方 [openai/codex](https://github.com/openai/codex) 对应版本的源码与调用链为第一手资料，先查官方实现
- 优先使用用户提供或本机已有的官方仓库，核对来源、版本或提交；资料不足时再查官方对应版本的源码、测试与文档
- 三方仓库只能提供排查线索或实现参考，不能代替官方行为依据；与官方不一致时回到官方源码核实，不直接照搬三方结论
- 结论注明适用版本或提交，区分官方事实、三方参考与本项目推断；官方证据不足时保留不确定性
+开发、排障和代码审查先按[问题与方案依据](../../../CONTRIBUTING.md#问题与方案依据)核实问题与方案。涉及 Codex 行为时执行其中的官方行为优先约束：对应版本的官方源码优先，以透明转发和最小必要适配为默认方案，先判断偏离是否必要再评价实现

 ## 执行与收尾

-1. 确认工作区、任务范围与已有改动，先定位事实归属、同类实现和调用链，再修改；编码前只读[项目约定](../../../CONTRIBUTING.md#项目约定)的对应条目
-2. 自审完整差异，处理本次引入的职责越界、重复规则、冗余状态与无依据分支；仅审查时报告，不自行修复
-3. 按变更范围读取[验证](../../../CONTRIBUTING.md#验证)，区分通过、失败、跳过与未执行；提交时补读[提交约定](../../../CONTRIBUTING.md#项目约定)
-4. 交付说明实际结果与验证缺口；页面证据和后端生命周期检查按上表执行，不把构建通过当作行为验收
+1. 遵守已提供的 [AGENTS.md](../../../AGENTS.md)，按其 CodeGraph 约定定位代码；确认工作区、任务范围与已有改动，找到事实归属、同类实现和调用链，补齐上表命中规范及[项目约定](../../../CONTRIBUTING.md#项目约定)对应条目后再修改
+2. 自审完整差异，处理本次引入的职责越界、重复规则、冗余状态与无依据分支；删除或替换功能时一并清理失效的配置、类型、调用、测试与文档，已部署数据和公开合同仍遵守所属迁移及兼容规则；仅审查时报告，不自行修复
+3. 常规文档只写当前状态；有文档差异时执行[文档检查](references/documentation.md)，没有时只确认现有说明是否失真，普通开发不自动修改 `release/notes.md`
+4. 按变更范围执行[验证](../../../CONTRIBUTING.md#验证)及其停止条件，沿用本轮有效证据与用户已确定的验收分工，区分通过、失败、跳过与未执行；提交时补读[提交约定](../../../CONTRIBUTING.md#项目约定)
+5. 交付实际结果与验证缺口；前端按[前端流程](references/frontend.md)核对最终差异和运行证据，后端按上表检查生命周期，不把构建通过当作行为验收
+
+## 测试维护
+
+- 测试随当前功能维护，名称、夹具和断言描述当前输入、行为与结果；功能变更时优先更新所属模块的现有用例，不为每次改动叠加一组记录变更经过的测试
+- 清理只证明旧字段、旧路由或旧实现已经消失的用例与附带断言；未知字段校验使用合法请求基线加无业务含义的未知字段，避免因缺少必填项等其他错误而误通过
+- 同一层对同一行为的重复覆盖合并为清晰的场景矩阵，复用相邻测试夹具；跨层测试确有不同职责或失败路径时保留，不为统一而扩大测试辅助抽象
+- 断言可观察的行为与业务不变量，避免复述结构体赋值、罗列表列或字段清单、匹配 SQL 文本与源码布局；项目明确要求的架构边界检查继续维护
+- 当前协议兼容、数据读取兼容、安全边界、并发和资源生命周期仍需覆盖，不按 `old`、`legacy` 等名称机械删除，也不能用改名代替无效用例清理
+- 不在仓库中新增或保留迁移 SQL 专项测试，包括迁移文本、schema 演变与指定版本升级用例；需要验证迁移执行、数据保留或回滚时，在临时目录编写一次性验证并使用隔离数据库，测试通过即可，临时脚本不纳入维护测试集
+- 持久化功能测试使用当前完整 schema，验证现行读写、事务与数据约束；插件运行时状态迁移等业务能力按当前功能测试，不归为迁移 SQL 专项测试

 ## 后端注释

 - 每个 Rust 文件顶层使用简短的中文 `//!` 注释说明文件职责，覆盖生产源码、测试与构建脚本；测试文件说明测试范围或辅助用途，生成文件同步维护生成器
 - 注释不使用中文或英文句号，多句说明按语义分行；保留 URL、版本号、标识符和代码示例中有语义的点号
 - 文件说明聚焦当前功能与职责边界，局部注释解释原因和约束，避免复述代码或记录修改经过
-
-## 文档硬约束
-
-**常规文档只描述当前状态，不写变更历史**，这项检查适用于每次开发收尾，不限于专门的文档任务
-
- 动笔前确定读者、所属章节与必须说明的当前事实，没有必要就不改文档
- 有文档差异时执行[文档检查](references/documentation.md)，逐段决定保留、改写、删除或移入任务报告，未完成内容审查不能称文档已检查
- 没有文档差异时只确认现有说明是否失真；普通开发不自动修改 `release/notes.md`

 ## 问题与方案依据

 开发、创建 PR 和审查都先核实待解决的问题、触发条件与预期行为，再确定或评估实现。区分问题发生版本、目标分支现状和本次变更后的行为，不把需求描述、PR 描述或第三方项目的做法直接当成事实。目标分支已修复的问题，应说明当前仍需补齐的差异，不能据此否定旧版本中的问题

-涉及上游协议、客户端行为或兼容性时，以对应版本的官方源码为首要资料。优先读取用户提供或本机已有的官方源码，核对仓库来源、版本或提交；本地资料不足时查官方仓库的对应版本源码，再结合官方测试、文档、发布说明和运行证据。第三方资料只作线索或补充。引用具体文件、符号或行号，对外引用优先使用固定提交的源码链接；源码不可得或版本不匹配时说明证据缺口，不把最新实现当成当前部署行为。无上游依赖的内部变更，以本项目代码、合同和运行证据为依据
+涉及上游协议、客户端行为或兼容性时，遵守以下依据与行为约束；无上游依赖的内部变更以本项目代码、合同和运行证据为依据

-官方已有同一场景的处理方式时，优先沿用其协议语义、职责归属和解决路径，检查是否只需复用已有能力或正确传递官方合同。新增覆盖配置、补偿逻辑或采用第三方兼容方案，应说明官方路径为何不足；偏离官方方案需有本项目的实际约束和验证依据，不机械照搬源码，也不默认接受已有提案
+- **资料来源**：以对应版本的官方源码与调用链为首要资料，Codex 对照 [openai/codex](https://github.com/openai/codex)。先查用户提供或本机已有的仓库，核对来源、版本或提交；不足时再查官方对应版本源码，结合测试、文档、发布说明和运行证据。三方资料只作线索或实现参考，不能替代官方依据
+- **证据表达**：引用具体文件、符号或行号，对外优先使用固定提交的源码链接；注明适用版本，区分官方事实、三方参考与本项目推断。源码不可得或版本不匹配时报告缺口，不把最新实现当作部署行为，也不把自定义策略写成官方要求
+- **默认方案**：Codex 兼容性优先保持官方行为，以透明转发和最小必要适配为默认方案。沿用官方协议语义、职责归属和解决路径，优先复用已有能力或正确传递合同，不额外解释请求意图、扩展工具权限或改变续接语义
+- **问题核实**：对照官方与 CPR 的实际请求、响应及状态生命周期，检查本项目是否误解、改写、遗漏或破坏合同；分别说明源码推断、代理链路复现与官方直连结果。真实上游报错不自动等于 CPR 缺陷
+- **审查官方对接**：审查 OpenAI 官方上游与 Codex 的对接时，默认二者兼容、直接对接正常。不得仅凭自行构造的异常上游数据揣测官方不兼容，据此报告缺陷、提出改进建议或要求防御分支与测试；特定版本或场景的例外须有真实响应或实际复现证据
+- **偏离依据**：新增覆盖配置、补偿逻辑或三方兼容方案前，说明官方路径为何不足、本项目实际约束、最小改动、行为代价及验证。补偿后成功、测试通过或三方采用同一做法不能单独证明必要性；依据不足时保持现有合同并报告缺口，不先加分支再倒推理由。用户明确要求的行为变更限定在授权范围内
+- **网关职责**：调度、隔离和资源管理按网关职责评估，不机械照搬单客户端实现，不因官方客户端没有同类池策略就判错，也不任意改变客户端可观察行为。新增默认限制或回收阈值须有容量依据，并验证续接、重试与延迟影响

+AI 进行前端开发或审查时，执行[前端流程](.agents/skills/cpr-dev-guide/references/frontend.md)，覆盖页面、组件、弹窗、表单及局部文案和样式。用户指定设计技能时使用该技能；未指定时，只有任务明确需要建立或重塑视觉方向才使用 `$frontend-design`。新增页面也优先沿用 [管理端主题](docs/theme.md) 和已有设计，设计技能不构成重做页面的理由

 开发前查找原页面、同类页面及 `modules/ui/src/components` 中的基础组件，明确参考实现和可复用部分，再确定最小改动。只有原设计不能满足本次操作或存在具体问题时才调整结构，并在 PR 中说明原因；不顺带换风格、重排无关区域或增加重复的模式入口。需要扩展时在对应职责层修改；局部样式的适用范围遵循主题文档，不一律禁止，也不靠页面覆盖掩盖共用组件的问题
