## 文档规范
|
||||
|
||||
### 方案规范 (docs/)
|
||||
### 文档编号规范（design/pdd/ + design/prd/）
|
||||
|
||||
**编号规则**：创建新方案前必须先通过 shell 命令确认当前实际最大编号（Unix: `ls docs/` / Windows: `dir docs\`），禁止使用上下文中缓存的编号，如遇冲突自动递增
|
||||
`design/pdd/`（方案文档）和 `design/prd/`（需求文档）使用相同的命名格式，但**各自独立编号**：
|
||||
|
||||
**方案文档结构**（6 项）：
|
||||
1. **背景与目标** - 问题描述、预期目标
|
||||
2. **需求分析** - 功能需求、非功能需求
|
||||
3. **方案设计** - 架构设计、模块划分、接口定义
|
||||
4. **实现计划** - 任务拆解、优先级、时间估算
|
||||
5. **风险评估** - 潜在风险、缓解措施
|
||||
6. **验收标准** - 可验证的完成条件
|
||||
```
|
||||
<序号>-<简短描述>.md
|
||||
```
|
||||
|
||||
### 进度同步规范 (docs/roadmap.md)
|
||||
规则：
|
||||
- 序号使用数字，从 1 开始递增。**创建前必须通过 shell 命令确认目标目录当前实际最大编号再加 1：**
|
||||
```bash
|
||||
# 查 design/pdd/ 的最大编号
|
||||
ls design/pdd/ 2>/dev/null | grep -E '^\d+-' | sort -t- -k1 -n | tail -1 | cut -d- -f1
|
||||
# 查 design/prd/ 的最大编号
|
||||
ls design/prd/ 2>/dev/null | grep -E '^\d+-' | sort -t- -k1 -n | tail -1 | cut -d- -f1
|
||||
# 无输出则从 1 开始
|
||||
```
|
||||
禁止使用上下文中缓存的编号。
|
||||
- 描述：中文，简短概括主题
|
||||
- 两个目录各自独立编号——`design/pdd/` 已有 `3-` 时，`design/prd/` 的新文件仍从当前最大号 +1 开始，互不影响
|
||||
|
||||
完成一项实施后，必须检查 `docs/roadmap.md` 是否存在对应内容；若存在，必须同步标记为完成：
|
||||
方案文档（`design/pdd/`）应包含：
|
||||
- 背景与目标
|
||||
- 需求推演概要（需求拆解、边界识别、关键假设的简要推演）
|
||||
- 当前问题分析
|
||||
- 架构决策记录（重大技术选型、架构变更的决策过程与理由）
|
||||
- 设计方案（含架构图/流程图）
|
||||
- 实施步骤
|
||||
- 验证标准
|
||||
- 回滚方案（如适用）
|
||||
|
||||
- **Step / Phase 状态行**：对应 Step 加 ✅ 标记；Phase 章节末尾「状态」行从 ⏳ 改为 ✅ Phase X 全部交付物已完成
|
||||
- **里程碑表**：更新对应里程碑状态从 ⏳ 改为 ✅ + 完成日期
|
||||
- **依赖关系图（Mermaid）**：节点 `class` 从 `pending` / `core` 改为 `done`，必要时更新节点摘要
|
||||
- **文末「已完成 / 进行中阶段」列表**：追加一行 `- ✅ Phase X — 一句话要点`
|
||||
- **顶部「当前状态」**：补充新完成 Phase，更新「下一步」指向
|
||||
示例：
|
||||
- `design/pdd/1-ui-components重构方案.md`
|
||||
- `design/prd/1-用户认证需求.md`
|
||||
- `design/pdd/2-数据库迁移方案.md`
|
||||
|
||||
参考案例：2026-07-05 完成 Phase 7 SqliteStore 时同步更新 6 处（顶部状态 / Phase 章节 / 依赖图 / M3 / 下一步行动 / 已完成列表）。

|
||||
|
||||
### 设计目录（design/）
|
||||
|
||||
项目根下的 `design/` 目录集中管理所有设计相关的文件，供人类和 agent 共同读写。
|
||||
|
||||
| 子目录 | 内容 | 谁写 | 谁读 |
|
||||
|--------|------|------|------|
|
||||
| `design/pdd/` | 方案设计文档（PDD）→ 架构方案、设计决策、转换方案 | proposal→writer pipeline | Think 参考、Build 实现、Vet 审查 |
|
||||
| `design/prd/` | 需求文档（PRD）→ 功能需求、用户故事、验收标准 | 人写 | Think 分析、Proposal 写方案时参考 |
|
||||
| `design/prototype/` | **OD 导出的原型 HTML** → 视觉稿、交互原型、页面 layout | OD 桌面版导出 | Think 分析结构、Build 对照实现 |
|
||||
| `design/notes/` | 笔记记录 → 零散想法、会议纪要、调研速记 | 人写 | 各 agent 参考 |
|
||||
| `design/roadmap/` | 路线图 → 里程碑规划、版本计划、优先级列表 | 人写 | Proposal 排期参考 |
|
||||
| `design/DESIGN.md` | 设计系统（品牌规范）→ 色板、字体、间距、语气 | OD 导出 / 人维护 | Think 提取 token、Build 同步到 `src/` |
|
||||
| `design/tokens.css` | 设计 Token CSS → 从 DESIGN.md 提取的 CSS 变量 | 人同步 / agent 同步 | 所有 Svelte 组件引用 |
|
||||
|
||||
**访问规则：**
|
||||
- 读：所有 agent 默认可读（`read_file` 不需要额外权限）
|
||||
- 写：writer agent 可通过 `"design/**": allow` 写入 `design/` 下任意子目录
|
||||
- 注意：`prototype/` 由 OD 桌面版导出，agent 只读不写；`DESIGN.md` 和 `tokens.css` 建议手动维护或 agent 写入时确认后再改
|
||||
|
||||
**兜底规则：** 文档类型不在上表时（如教程、接口文档、临时记录），或目标目录不存在时 → **向用户提问确认路径**。不允许自行推断存放位置。

## Feature 组合
|
||||
|
||||
AG Core 通过 Cargo features 让下游按需选择模块，跳过不需要的编译单元和重型依赖。`default = ["full"]` 保持向后兼容——不指定 features 时行为与 v0.3.0 一致。
|
||||
|
||||
### 快捷组合
|
||||
|
||||
| 组合 | 场景 | 包含的 features |
|
||||
|------|------|----------------|
|
||||
| `full`（default） | 全栈使用，兼容 v0.3.0 | 全部 16 个 feature |
|
||||
| `light` | 生产常用，跳过 Anthropic/DeepSeek/Qwen/Ollama | llm + provider-openai + tools + tools-mcp + memory + agent + engine + prompt + document |
|
||||
| `chat` | 纯对话（跳过 SQLite 和 MCP） | agent + provider-openai |
|
||||
| `multi` | 多 Agent 复合（chat + subagent + switch + checkpointer） | engine + provider-openai |
|
||||
|
||||
### Cargo.toml 配置示例
|
||||
|
||||

|
||||
# 默认全栈（兼容 v0.3.0）

### 模块级 features
|
||||
|
||||
如需更细粒度控制，可单独启用模块级 features：
|
||||
|
||||
| Feature | 覆盖内容 | imply |
|
||||
|---------|---------|-------|
|
||||
| `document` | Document + RecursiveCharacterSplitter | — |
|
||||
| `llm-types` | Message / ToolDef / Usage 等 IR 类型 | — |
|
||||
| `prompt` | PromptTemplate + PromptComposer | `llm-types` |
|
||||
| `llm` | Provider trait + LlmCycle + hooks + compact + embedding + mock | `llm-types` |
|
||||
| `tools` | BaseTool + ToolRegistry | `llm-types` |
|
||||
| `tools-mcp` | McpClient（Stdio/StreamableHttp） | `tools` |
|
||||
| `memory` | MemoryStore + Conversation + VectorStore + KnowledgeGraph + Retriever | `document` + `llm` |
|
||||
| `memory-sqlite` | SqliteStore | `memory` |
|
||||
| `agent` | Agent + Builder + Session + ContextSlot + Summary | `llm` + `tools` + `memory` |
|
||||
| `engine` | SessionManager + Checkpointer + SubAgent + Switch | `agent` |
|
||||
| `provider-openai` | OpenAI Provider 实现 | `llm` |
|
||||
| `provider-anthropic` | Anthropic Provider 实现 | `llm` |
|
||||
| `provider-openai-response` | OpenAI Response API（`POST /responses`）Provider 实现 | `llm` |

||||
| `provider-deepseek` | DeepSeek Provider 实现 | `llm` |
|
||||
| `provider-qwen` | Qwen Provider 实现 | `llm` |
|
||||
| `provider-ollama` | Ollama Provider 实现 | `llm` |
|
||||
| `tracing-init` | `init_tracing()` 函数 | — |

||||
|
||||
## 升级指南（v0.3.0 → v0.3.2）
|
||||
|
||||
### LlmProvider trait 路径变更
|
||||
|
||||
v0.3.2 起，`LlmProvider` trait 及其关联类型 `ProviderCapabilities` / `ProviderFeatures` 从 `provider` 模块移至 `llm` 模块根级别，归属 `#[cfg(feature = "llm")]` 而非 `any(provider-*)`。纯 Mock 场景不再需要引入任何 provider feature。
|
||||
|
||||
| 旧路径（v0.3.0） | 新路径（v0.3.2） |
|
||||
|------------------|------------------|
|
||||
| `agcore::llm::provider::LlmProvider` | `agcore::llm::LlmProvider` |
|
||||
| `agcore::llm::provider::ProviderCapabilities` | `agcore::llm::ProviderCapabilities` |
|
||||
| `agcore::llm::provider::ProviderFeatures` | `agcore::llm::ProviderFeatures` |
|
||||
|
||||
**向后兼容**：`provider` 模块中保留了 `pub use` 重导出，老路径仍可编译。但推荐迁移至新路径，未来版本可能移除重导出。
|
||||
|
||||
`ProviderConfig` / `ProviderType` / `create_provider()` 等 provider 创建逻辑仍在 `agcore::llm::provider` 下，无需迁移。
|
||||
|
||||
### 迁移步骤
|
||||
|
||||
```bash
|
||||
# 1. 全局替换 use 路径
|
||||
sed -i 's/agcore::llm::provider::LlmProvider/agcore::llm::LlmProvider/g' src/**/*.rs
|
||||
sed -i 's/agcore::llm::provider::{LlmProvider/agcore::llm::{LlmProvider/g' src/**/*.rs
|
||||
|
||||
# 2. 验证编译
|
||||
cargo build --features "full"
|
||||
```

# AG Core v0.3.2 Step 1（Phase 20）— Cargo Features 基础设施改造实施方案
|
||||
|
||||
## 1. 背景与目标
|
||||
|
||||
**背景**：agcore 是一个 Rust 编写的智能体核心工具箱，目前约 23,718 行、66 个源文件。v0.3.0 发布后，所有模块在编译时全量捆绑，下游用户无法按需选择模块，即使只使用 LLM 对话也需要编译 sqlite / MCP / agent 引擎等全部依赖。
|
||||
|
||||
**目标**：通过 Cargo features 拆分让下游按需选择模块。Step 1 是基础设施变更 —— `Cargo.toml` features 定义 + 依赖 optional 化 + 必要的子模块 cfg 门控，编译通过后打 checkpoint。
|
||||
|
||||
**预期效果**：
|
||||
- `default = ["full"]` → v0.3.0 用户零迁移成本
|
||||
- 最小组合（`document`）零重型外部依赖（仅依赖始终编译的轻量依赖：serde/serde_json/thiserror/async-trait/tracing）
|
||||
- 纯对话组合（`chat + provider-openai`）仅需 ~10 个依赖，不含 sqlite / MCP / engine
|
||||
|
||||
## 2. 需求分析
|
||||
|
||||
### 2.1 约束条件
|
||||
|
||||
| # | 约束 | 说明 |
|
||||
|---|------|------|
|
||||
| 1 | `default = ["full"]` | 保持向后兼容，v0.3.0 用户零迁移成本 |
|
||||
| 2 | `document` feature 零重型外部依赖（仅依赖始终编译的轻量依赖：serde/serde_json/thiserror/async-trait/tracing） | 纯 std + 始终编译的轻量依赖（serde/serde_json/thiserror/async-trait/tracing） |
|
||||
| 3 | tokio 从 `["full"]` 拆细 | 已验证全库无 net/fs/signal 使用，拆为 `["rt", "sync", "time", "macros", "process", "io-util"]` |
|
||||
| 4 | 重型依赖全部 optional | tokio、reqwest、rusqlite、tracing-subscriber、tokio-stream、futures、futures-util、futures-core、bytes、async-stream、tokio-util、time |
|
||||
| 5 | 始终编译的轻量依赖 | serde、serde_json、thiserror、async-trait、tracing |
|
||||
|
||||
### 2.2 关键决策
|
||||
|
||||
| # | 决策 | 理由 |
|
||||
|---|------|------|
|
||||
| 1 | `tools` feature 必须 `imply tokio` | `src/tools/registry.rs` 使用 `tokio::time::timeout` |
|
||||
| 2 | `pub mod llm` 门控条件为 `any(feature = "llm-types", feature = "llm")` | `prompt → llm-types` 路径需要 llm 模块编译，但只需 types 子模块 |
|
||||
| 3 | 测试 dev-dependencies 加 `tokio = { version = "1", features = ["rt", "macros"] }` | 现有 `#[tokio::test]` 需要 tokio runtime |
|
||||
| 4 | 快捷组合名保持原名（chat/multi/light） | 文档中说明各组合包含的 feature 约束 |
|
||||
| 5 | `init_tracing()` 函数整体用 `#[cfg(feature = "tracing-init")]` 包裹 | 避免 `use tracing_subscriber` 出现在未启用 feature 时编译失败 |
|
||||
|
||||
## 3. 方案设计
|
||||
|
||||
### 3.1 Features 定义（完整 Cargo.toml `[features]` 草案）
|
||||
|
||||
```toml
|
||||

|
||||

### 3.2 依赖 optional 化方案
|
||||
|
||||
**始终编译（5 个，不参与门控）**：
|
||||
|
||||
```toml
|
||||
serde = { version = "1", features = ["derive"] }
|
||||
serde_json = "1"
|
||||
thiserror = "2"
|
||||
async-trait = "0.1"
|
||||
tracing = "0.1"
|
||||
```
|
||||
|
||||
**12 个依赖加 `optional = true`**：
|
||||
|
||||
| 依赖 | 原声明 | 新声明 |
|
||||
|------|--------|--------|
|
||||
| tokio | `{ version = "1", features = ["full"] }` | `{ version = "1", features = ["rt", "sync", "time", "macros", "process", "io-util"], optional = true }` |
|
||||
| reqwest | `{ version = "0.12", features = ["json", "stream"] }` | `{ version = "0.12", features = ["json", "stream"], optional = true }` |
|
||||
| rusqlite | `{ version = "0.32", features = ["bundled"] }` | `{ version = "0.32", features = ["bundled"], optional = true }` |
|
||||
| tracing-subscriber | `{ version = "0.3", features = ["env-filter"] }` | `{ version = "0.3", features = ["env-filter"], optional = true }` |
|
||||
| tokio-stream | `{ version = "0.1" }` | `{ version = "0.1", optional = true }` |
|
||||
| futures | `{ version = "0.3" }` | `{ version = "0.3", optional = true }` |
|
||||
| futures-util | `{ version = "0.3" }` | `{ version = "0.3", optional = true }` |
|
||||
| futures-core | `{ version = "0.3" }` | `{ version = "0.3", optional = true }` |
|

| bytes | `{ version = "1" }` | `{ version = "1", optional = true }` |
|

| async-stream | `{ version = "0.3" }` | `{ version = "0.3", optional = true }` |
|
||||
| tokio-util | `{ version = "0.7", features = ["rt", "sync"] }` | `{ version = "0.7", features = ["rt", "sync"], optional = true }` |
|
||||
| time | `{ version = "0.3", features = ["serde", "parsing", "formatting", "macros"] }` | `{ version = "0.3", features = ["serde", "parsing", "formatting", "macros"], optional = true }` |
|
||||
|
||||
**dev-dependencies 新增**：
|
||||
|
||||
```toml
|
||||
[dev-dependencies]
|
||||
tokio = { version = "1", features = ["rt", "macros"] }
|
||||
```
|
||||
|
||||
### 3.3 源文件改动清单
|
||||
|
||||
共涉及 **8 个文件**（预估 ~100 行改动）：`Cargo.toml`、`src/lib.rs`、`src/llm.rs`、`src/llm/cycle.rs`、`src/tools.rs`、`src/memory.rs`、`src/memory/store.rs`、`src/agent/session.rs`

```
|

**改动 1.3** — 11 个重型依赖逐行加 `optional = true`
|

#### 文件 3：`src/llm.rs`（当前约 12 行 → 改动后约 24 行）
|
||||
|
||||
**改动说明**：为每个子模块声明加 feature 门控。`types` 子模块在 `llm-types` 或 `llm` 任一 feature 启用时编译（`llm` imply `llm-types`，但 `prompt` 也 depend on `llm-types`）；其余子模块（compact/convert/cycle 等）仅在 `llm` feature 启用时编译。

#### 文件 3b：`src/llm/cycle.rs`（新增文件，约 35 行）
|
||||
|
||||
**改动说明**：`cycle.rs` 中使用 `crate::tools::ToolRegistry`（第 29 行），依赖 `tools` feature。工具相关字段和方法需加 `#[cfg(feature = "tools")]` 门控。
|
||||
|
||||
> ⚠️ 这是 Phase 22.7 原计划的门控变更，因为编译阻塞提前到 Step 1 执行。

|
||||
|

|
||||
#### 文件 4：`src/tools.rs`（当前约 13 行 → 改动后约 15 行）
|
||||
|
||||
**改动说明**：`mcp` 子模块及对应的 `pub use` 仅在 `tools-mcp` feature 启用时编译。其余子模块（base/error/permission/registry）始终在 `tools` feature 下编译。
|
||||
|
||||
```diff

#### 文件 5：`src/memory/store.rs`（当前约 62 行 → 改动后约 64 行）
|
||||
|
||||
**改动说明**：`sqlite_store` 子模块及其 `pub use` 仅在 `memory-sqlite` feature 启用时编译。
|
||||
|
||||
```diff
|
||||
//! MemoryStore 抽象接口与默认实现。

```
|

**说明**：`MemoryStore` trait、`EvictionConfig`、`EvictionPolicy` 等定义保持不变，不需要 cfg 门控。
|

|
||||
|
||||
#### 文件 6：`src/memory.rs`（当前约 32 行 → 改动后约 34 行）
|
||||
|
||||
**改动说明**：`SqliteStore` 的重新导出仅在 `memory-sqlite` feature 启用时编译。其余子模块声明和 `pub use` 保持不变（`memory` feature 门控由 `src/lib.rs` 负责）。
|
||||
|
||||
```diff

|
||||
#### 文件 7：`src/agent/session.rs`（新增文件，约 30 行）
|
||||
|
||||
**改动说明**：`session.rs` 中引用了 `crate::engine::*`（SessionMemoryEntry、SessionSnapshot、EngineError），而 `agent` feature 不含 `engine`（`engine = ["agent"]` 是反向依赖）。需要对 engine 相关导入和方法加门控。
|
||||
|
||||
> ⚠️ 阻塞 B3：`src/agent/session.rs:28-29` 无条件引用 `crate::engine::*`，在 `agent` feature 下编译时因缺少 engine 而失败。
|
||||
|
||||
```diff
|

```
|
||||
|
||||
**说明**：`Session` 结构体本身以及不依赖 engine 的方法（如 `new()`、`add_message()`、`get_history()`）保持无门控，仅在 `agent` feature 下编译即可。

## 4. 实施步骤
|
||||
|
||||
按 **3 个 commit** 粒度执行，每个 commit 后编译验证。
|
||||
|
||||
### Commit 1：Cargo.toml features 定义 + 依赖 optional 化
|
||||
|
||||
**涉及文件**：仅 `Cargo.toml`
|
||||
|
||||
**操作清单**：
|
||||
|
||||
1. 在 `[package]` 之后、`[dependencies]` 之前插入 `[features]` 表（16 个 features + 4 个快捷组合，约 45 行）
|
||||
2. tokio features 从 `["full"]` 改为 `["rt", "sync", "time", "macros", "process", "io-util"]` 并加 `optional = true`
|
||||
3. reqwest / rusqlite / tracing-subscriber / tokio-stream / futures / futures-util / futures-core / bytes / async-stream / tokio-util / time 共 11 个依赖加 `optional = true`
|
||||
4. 在 `[dependencies]` 之后新增 `[dev-dependencies]` 加 `tokio = { version = "1", features = ["rt", "macros"] }`
|
||||
|
||||
**验证**：
|
||||
```bash
|
||||
cargo build --no-default-features # 不依赖任何 optional crate，应通过
|
||||
cargo build -F document # 零外部依赖，应通过
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Commit 2：cfg 门控（pub mod + pub use + init_tracing）
|
||||
|
||||
**涉及文件**：`src/lib.rs`、`src/llm.rs`、`src/llm/cycle.rs`、`src/tools.rs`、`src/memory/store.rs`、`src/memory.rs`、`src/agent/session.rs`
|
||||
|
||||
**操作清单**：
|
||||
|
||||
按文件逐一执行：
|
||||
|
||||
1. `src/lib.rs` — 7 个 `pub mod` 加 `#[cfg(feature = "...")]`、`Document` pub use 加 cfg、`init_tracing` 整体用 `#[cfg(feature = "tracing-init")]` 包裹
|
||||
2. `src/llm.rs` — 10 个子模块按 `llm-types` / `llm` / provider 分类门控
|
||||
3. `src/llm/cycle.rs` — `ToolRegistry` 导入加 `#[cfg(feature = "tools")]`，工具字段和方法加相同门控
|
||||
4. `src/tools.rs` — `pub mod mcp` 和 `pub use mcp::*` 加 `#[cfg(feature = "tools-mcp")]`
|
||||
5. `src/memory/store.rs` — `pub mod sqlite_store` 和 `pub use sqlite_store::SqliteStore` 加 `#[cfg(feature = "memory-sqlite")]`
|
||||
6. `src/memory.rs` — `pub use store::SqliteStore` 加 `#[cfg(feature = "memory-sqlite")]`

7. `src/agent/session.rs` — engine 相关导入加 `#[cfg(feature = "engine")]`，to_snapshot/from_snapshot/restore_memory 加相同门控
|
||||
|
||||
**验证**：
|
||||
```bash
|
||||
cargo build -F "full" # 全量回归
|
||||
cargo build -F "prompt" # 验证 llm::types imply 路径
|
||||
cargo build -F "tools" # 验证 tokio imply 路径
|
||||
cargo build -F "memory" # 验证记忆模块不含 sqlite
|
||||
cargo build -F "chat,provider-openai" # 纯对话组合
|
||||
cargo build -F "chat,provider-openai,tools-mcp" # 带 MCP 对话
|
||||
```
|
||||
|
||||

|
||||
|
||||
### Commit 3：Checkpoint 全量验证
|
||||
|
||||
**操作清单**：
|
||||
|
||||
1. 完整的验证矩阵执行（见第 5 节）
|
||||
2. `cargo test -F "full"` 确认 427 passed
|
||||
|
||||
**验证**：
|
||||
```bash
|
||||
cargo test -F "full"
|
||||
cargo build -F "light"
|
||||
cargo build -F "multi"
|
||||
```
|
||||
|
||||
## 5. 验证标准
|
||||
|
||||
### 编译验证矩阵
|
||||
|
||||
| 命令 | 验证目标 | 预期结果 |
|
||||
|------|---------|---------|
|
||||
| `cargo build --no-default-features` | 空 crate | 编译通过（无模块） |
|
||||
| `cargo build -F "full"` | 全量回归 | 编译通过，与 v0.3.0 语义一致 |
|
||||
| `cargo test -F "full"` | 测试回归 | `427 passed` |
|
||||
| `cargo build -F "document"` | 文档模块独立 | 编译通过，零外部依赖 |
|
||||
| `cargo build -F "prompt"` | 提示词独立 | 编译通过，`llm::types` imply 路径正确 |
|
||||
| `cargo build -F "tools"` | 工具独立 | 编译通过，tokio imply 路径正确 |
|
||||
| `cargo build -F "memory"` | 记忆模块独立编译 | ✅ 不含 sqlite（依赖 B1/B2 修复） |
|
||||
| `cargo build -F "memory-sqlite"` | 含 SQLite 的记忆模块 | ✅ 含 rusqlite |
|
||||
| `cargo build -F "agent"` | Agent 独立编译 | ✅ 含 llm+tools+memory，不含 engine（依赖 B1/B3 修复） |
|
||||
| `cargo build -F "engine"` | Engine 独立编译 | ✅ imply agent → llm+tools+memory |
|
||||
| `cargo build -F "chat,provider-openai"` | 纯对话组合 | 编译通过，不含 MCP、sqlite |
|
||||
| `cargo build -F "chat,provider-openai,tools-mcp"` | 带 MCP 对话 | 编译通过，含 reqwest 无 sqlite |
|
||||
| `cargo build -F "light"` | 生产常用组合 | 编译通过 |
|
||||
| `cargo build -F "multi"` | 多 provider 组合 | 编译通过 |
|
||||
|
||||
### 验证操作指令
|
||||
|
||||
每次编译验证后执行（验证编译产物不含意外符号）：
|
||||
|
||||
```bash
|
||||
# 确认空 crate 确实没有模块符号
|
||||
cargo build --no-default-features 2>&1 && echo "OK"
|
||||
|
||||
# 确认 document 零外部依赖（无 reqwest/rusqlite 等符号）
|
||||
cargo build -F "document" 2>&1 && echo "OK"
|
||||
|
||||
# 全量构建 + 测试
|
||||
cargo build -F "full" 2>&1 && cargo test -F "full" 2>&1 | tail -5
|
||||
```
|
||||
|
||||
### 验证通过条件
|
||||
|
||||
- 所有 14 条编译验证命令返回 exit code 0
|
||||
- `cargo test -F "full"` 输出 `427 passed`（与 v0.3.0 基线一致，不要求测试数精确匹配，但必须全部通过且数量合理）
|
||||
- 无 `unused import` / `unused variable` / `dead code` warning（由 `#[cfg]` 引起的新 warning 需逐一修复）
|
||||
|
||||
## 6. 风险评估
|
||||
|
||||
| 风险 | 等级 | 缓解措施 |
|
||||
|------|------|---------|
|
||||
| **tokio features 拆细遗漏**：某些代码路径用到 net/fs/signal | 低 | 已通过 SA（静态分析）验证全库无相关使用 |
|
||||
| **`#[tokio::test]` 编译失败**：测试代码无 tokio runtime | 低 | `[dev-dependencies]` 添加 `tokio = { version = "1", features = ["rt", "macros"] }` |
|
||||
| **下游 transitive tokio features 缩小**：依赖 agcore 的 crate 之前通过 agcore 间接获得 `full` tokio，现在范围缩小 | 中 | Phase 27 README 发布说明中明确告知迁移方案；下游如需完整 tokio 需自行添加 |
|
||||
| **imply 链未闭合**：某个 feature 依赖了未 imply 的 feature | 低 | 7 种特征组合全部逐条构建验证；features 定义中有交叉引用的全部显式列出 |
|
||||
| **unused cfg warning**：某些 `#[cfg]` 标记导致编译 warning | 低 | 每个 commit 后检查编译器输出，发现后立即修复 |
|
||||
| **测试依赖循环**：dev-deps 与普通 deps 版本冲突 | 低 | dev-deps 的 tokio 版本与主依赖保持一致 (`version = "1"`，由 cargo 自动选择兼容版本) |
|
||||
| **memory 跨模块 imply 链** | **高** | memory 模块依赖 llm（conversation/vector_store）、tokio（knowledge）、time（types），imply 链必须完整传递 | `memory` feature 定义已包含 `llm`、`tokio`、`time`；验证矩阵覆盖 memory 独立编译 |
|
||||
| **跨模块引用未门控** | **高** | provider.rs 依赖 reqwest、cycle.rs 依赖 ToolRegistry、session.rs 依赖 engine，Step 1 必须添加 cfg 门控 | provider 模块 cfg 改为 provider-xxx 条件；cycle.rs 加 tools 门控；session.rs 加 engine 门控 |

# AG Core v0.3.2 Step 3（Phase 26–27）— 验证固化 + 文档更新实施方案
|
||||
|
||||
## 1. 背景与目标
|
||||
|
||||
**背景**：agcore v0.3.2 Step 1（Phase 20–25）已交付 —— Cargo features 拆分基础设施改造全部完成，所有模块 `#[cfg]` 门控注入完毕，依赖全部 optional 化，`default = ["full"]` 保持向后兼容。当前项目处于已改造完成但未经 CI 固化、无文档指引的状态。
|
||||
|
||||
**当前状态快照**：
|
||||
- v0.3.0 → v0.3.2 Step 1：68 个源文件，23,765 行
|
||||
- 16 个 features（10 模块级 + 5 provider + 1 工具）+ 4 个快捷组合
|
||||
- `cargo test --features "full"`：427 passed
|
||||
- 7 种 feature 组合的 `cargo test --lib` 已全部通过（full / light / chat / chat+mcp / multi / multi+mcp / clippy），无需修复 cfg 遗漏
|
||||
- 但 `cargo test`（不带 `--lib`）会因 18 个 example 缺少 `required-features` 而失败
|
||||
- 项目无 CI/CD 配置
|
||||
|
||||
**目标**：通过 Step 3 将 features 体系验证固化到 CI 中，消除编译死代码警告，完成文档指引，使 v0.3.2 达到可发布状态。
|
||||
|
||||
**预期效果**：
|
||||
- 每次提交自动验证 7 种 feature 组合的编译 + 测试（零 warning）
|
||||
- 18 个 example 各自标注准确的 `required-features`，外树用户可一键运行
|
||||
- `cargo clippy --all-features -- -D warnings` 零告警
|
||||
- README 含完整 feature 表 + `Cargo.toml` 配置示例 + 升级指南，新用户 5 分钟内可选定组合
|
||||
- roadmap 同步更新
|
||||
|
||||
## 2. 需求分析
|
||||
|
||||
### 2.1 功能需求
|
||||
|
||||
| # | 需求 | 说明 | 对应工作 |
|
||||
|---|------|------|---------|
|
||||
| F1 | LlmProvider trait 不应依赖具体 provider feature | trait 自身不依赖 reqwest 或任何 provider 实现，纯 Mock 场景也应可用 | 工作 0 |
|
||||
| F2 | 每个 example 通过 `cargo run --example xxx` 正确编译 | 18 个 example 各有精确的最小 features 声明 | 工作 1 |
|
||||
| F3 | CI 自动验证 7 种特征组合的编译与测试 | push / PR 触发 | 工作 2 |
|
||||
| F4 | 所有 feature 组合下 0 个编译器警告 | 消除 dead_code 等警告 | 工作 3 |
|
||||
| F5 | README 提供完整的 feature 选择指引 | 表格 + 场景推荐 + Cargo.toml 示例 | 工作 5（Phase 27） |
|
||||
| F6 | example 文件顶部标注所需 features | 用户可一键复制运行命令 | 工作 5（Phase 27） |
|
||||
| F7 | roadmap 状态同步 | 总入口 + v0.3.2 子文档 | 工作 5（Phase 27） |
|
||||
|
||||
### 2.2 非功能需求
|
||||
|
||||
| # | 需求 | 指标 | 对应工作 |
|
||||
|---|------|------|---------|
|
||||
| N1 | 向后兼容 | `default = ["full"]` 行为与 v0.3.0 一致，427 tests passed | 全部 |
|
||||
| N2 | CI 时效 | 全矩阵 ≤ 10 分钟 | 工作 2 |
|
||||
| N3 | 最少侵入 | 不改动功能逻辑，仅 cfg / 配置 / 文档变更 | 全部 |
|
||||
|
||||
### 2.3 推演概要
|
||||
|
||||
**需求拆解**：从当前编译验证结果出发，发现三类待解决问题：
|
||||
1. **架构归属问题**——`LlmProvider` trait 定义在 provider 模块门控下，语义上应归属 `llm` 基础设施。同时其返回类型 `ProviderCapabilities` / `ProviderFeatures` 也必须一并移出
|
||||
2. **example 可编译性问题**——18 个 example 无 `required-features`，多组合下 `cargo test` 失败
|
||||
3. **代码质量问题**——`session.rs` 中 `bundle()` 方法在 `chat` 组合下 dead_code
|
||||
4. **工程缺失**——无 CI、README 无 features 说明、roadmap 未同步
|
||||
|
||||
**边界识别**：
|
||||
- 工作 0 仅移动 trait 及关联类型定义，不改变公开 API 签名
|
||||
- 工作 1 的 required-features 是最小集合，不添加冗余 feature
|
||||
- 工作 2 的 CI 仅验证编译 + 单元测试，不包含集成测试
|
||||
- 工作 5 的文档更新不涉及新的功能描述
|
||||
|
||||
**非目标声明**：
|
||||
- 不新增 feature 组合（保持现有的 4 个快捷组合不变）
|
||||
- 不重构 `ProviderConfig` / `ProviderType` / `create_provider()` 等 provider 模块创建逻辑（仅移出 trait 和元数据结构体）
|
||||
- 不集成集成测试（CI 仅验证 `--lib` 单元测试 + example 编译验证）
|
||||
- 不改动 `Cargo.toml` 的 `[dependencies]` 声明
|
||||
- 不改变 `default = ["full"]` 的默认行为
|
||||
|
||||

## 3. 方案设计
|
||||
|
||||
### 3.1 总体架构调整
|
||||
|
||||
```
|
||||
工作 0 — 架构修正（LlmProvider trait 及关联类型归属调整）
|
||||
|
||||
当前：
|
||||
src/llm/provider.rs #[cfg(any(feature = "provider-openai", ...))]
|
||||
├─ pub trait LlmProvider { ... }
|
||||
├─ pub struct ProviderCapabilities { ... }
|
||||
├─ pub struct ProviderFeatures { ... }
|
||||
└─ pub fn capabilities(&self) -> ProviderCapabilities;
|
||||
|
||||
目标：
|
||||
src/llm/provider_trait.rs #[cfg(feature = "llm")]
|
||||
├─ pub trait LlmProvider { ... }
|
||||
├─ pub struct ProviderCapabilities { ... }
|
||||
├─ pub struct ProviderFeatures { ... }
|
||||
└─ pub fn capabilities(&self) -> ProviderCapabilities;
|
||||
src/llm/provider.rs #[cfg(any(feature = "provider-openai", ...))]
|
||||
└─ 各 provider 实现 + ProviderConfig / ProviderType / create_provider()
|
||||
src/llm.rs
|
||||
└─ pub use provider_trait::{LlmProvider, ProviderCapabilities, ProviderFeatures};
|
||||
|
||||
影响文件（6 个源文件 + 1 个新建）：
|
||||
- src/llm.rs — 添加 mod provider_trait 声明 + pub use 重导出
|
||||
- src/llm/provider_trait.rs — 新文件，trait + 关联类型定义移入
|
||||
- src/llm/provider.rs — 移出 trait + 关联类型
|
||||
- src/llm/provider/openai.rs — use super:: → use crate::llm::
|
||||
- src/llm/provider/anthropic.rs — 同上
|
||||
- src/llm/provider/ollama.rs — 同上
|
||||
- src/llm/provider/openai_compat.rs — 同上（两个 import 合并）
|
||||
```
|
||||
|
||||
### 3.2 各子项设计方案
|
||||
|
||||
#### 工作 0 — LlmProvider trait 归属修正
|
||||
|
||||
**设计方案**：
|
||||
1. 在 `src/llm/` 下新建 `provider_trait.rs`，门控为 `#[cfg(feature = "llm")]`
|
||||
2. 从 `src/llm/provider.rs` 中提取以下定义到新文件：
|
||||
- `pub trait LlmProvider`（含关联方法 `chat` / `chat_stream` / `capabilities`）
|
||||
- `pub struct ProviderCapabilities`（含字段 `features: ProviderFeatures`）
|
||||
- `pub struct ProviderFeatures`（含 8 个功能开关字段）
|
||||
3. `src/llm.rs` 中声明 `mod provider_trait;`，并 `pub use provider_trait::{LlmProvider, ProviderCapabilities, ProviderFeatures};`
|
||||
4. `src/llm/provider.rs` 移除上述定义，保留 `ProviderConfig` / `ProviderType` / `create_provider()` 等运行时代码
|
||||
5. 更新所有 import 路径（详见下方清单）
|
||||
|
||||
**Import 路径调整清单**：
|
||||
|
||||
现有写法 → 目标写法
|
||||
|
||||
| # | 文件 | 现有 import | 目标 import |
|
||||
|---|------|------------|------------|
|
||||
| 1 | `agent/builder.rs:16` | `use crate::llm::provider::LlmProvider;` | `use crate::llm::LlmProvider;` |
|
||||
| 2 | `agent/builder.rs:135`（test） | `use crate::llm::provider::{LlmProvider, ProviderCapabilities, ProviderFeatures};` | `use crate::llm::{LlmProvider, ProviderCapabilities, ProviderFeatures};` |
|
||||
| 3 | `agent/session.rs:35` | `use crate::llm::provider::LlmProvider;` | `use crate::llm::LlmProvider;` |
|
||||
| 4 | `agent/runtime.rs:21` | `use crate::llm::provider::LlmProvider;` | `use crate::llm::LlmProvider;` |
|
||||
| 5 | `llm/mock.rs:46` | `use crate::llm::provider::{LlmProvider, ProviderCapabilities, ProviderFeatures};` | `use crate::llm::{LlmProvider, ProviderCapabilities, ProviderFeatures};` |
|
||||
| 6 | `llm/cycle.rs:22` | `use crate::llm::provider::LlmProvider;` | `use crate::llm::LlmProvider;` |
|
||||
| 7 | `llm/cycle.rs:940,1401`（test） | `use crate::llm::provider::{ProviderCapabilities, ProviderFeatures};` | `use crate::llm::{ProviderCapabilities, ProviderFeatures};` |
|
||||
| 8 | `llm/provider/openai.rs:24` | `use super::{LlmProvider, ProviderCapabilities, ProviderFeatures};` | `use crate::llm::{LlmProvider, ProviderCapabilities, ProviderFeatures};` |
|
||||
| 9 | `llm/provider/anthropic.rs:21` | `use super::{LlmProvider, ProviderCapabilities, ProviderFeatures};` | `use crate::llm::{LlmProvider, ProviderCapabilities, ProviderFeatures};` |
|
||||
| 10 | `llm/provider/ollama.rs:14` | `use super::{LlmProvider, ProviderCapabilities};` | `use crate::llm::{LlmProvider, ProviderCapabilities};` |
|
||||
| 11 | `llm/provider/openai_compat.rs:18,21` | `use super::ProviderCapabilities;` + `use crate::llm::provider::LlmProvider;` | `use crate::llm::{LlmProvider, ProviderCapabilities};`（合并为一行） |
|
||||
| 12 | `llm/provider/registry.rs:6` | `use crate::llm::provider::{LlmProvider, ProviderConfig, ProviderType, create_provider};` | `use crate::llm::LlmProvider;` + `use crate::llm::provider::{ProviderConfig, ProviderType, create_provider};`（拆分） |
|
||||
|
||||
**示例文件 import 调整**：
|
||||
|
||||
| # | 文件 | 现有 import | 目标 import |
|
||||
|---|------|------------|------------|
|
||||
| 13 | `examples/end_to_end.rs:21` | `use agcore::llm::provider::{create_provider, LlmProvider, ProviderConfig, ProviderType};` | `use agcore::llm::LlmProvider;` + `use agcore::llm::provider::{create_provider, ProviderConfig, ProviderType};` |
|
||||
| 14 | `examples/context_slot_demo.rs:18` | `use agcore::llm::provider::LlmProvider;` | `use agcore::llm::LlmProvider;` |
|
||||
| 15 | `examples/streaming_events_demo.rs:19` | `use agcore::llm::provider::LlmProvider;` | `use agcore::llm::LlmProvider;` |
|
||||
| 16 | `examples/quick_start.rs:9` | `use agcore::llm::provider::LlmProvider;` | `use agcore::llm::LlmProvider;` |
|
||||
|
||||
**Breaking Change 声明**：
|
||||
|
||||
工作 0 是**非兼容性变更**，现有用户可能通过以下路径引用 `LlmProvider`：
|
||||
|
||||
| 旧路径（v0.3.0–v0.3.2 Step 1） | 新路径（v0.3.2 Step 3 后） |
|
||||
|--------------------------------|---------------------------|
|
||||
| `agcore::llm::provider::LlmProvider` | `agcore::llm::LlmProvider` |
|
||||
| `agcore::llm::provider::ProviderCapabilities` | `agcore::llm::ProviderCapabilities` |
|
||||
| `agcore::llm::provider::ProviderFeatures` | `agcore::llm::ProviderFeatures` |
|
||||
|
||||
**向后兼容方案（可选）**：在 `src/llm/provider.rs` 中添加 `#[cfg(feature = "llm")]` 门控的类型别名，让老路径仍然可用：
|
||||
```rust
|
||||
#[cfg(feature = "llm")]
|
||||
pub use super::provider_trait::LlmProvider;
|
||||
#[cfg(feature = "llm")]
|
||||
pub use super::provider_trait::ProviderCapabilities;
|
||||
#[cfg(feature = "llm")]
|
||||
pub use super::provider_trait::ProviderFeatures;
|
||||
```
|
||||
**推荐**：用户应迁移到新路径 `agcore::llm::LlmProvider`，`provider` 模块仅保留 `ProviderConfig` / `ProviderType` / `create_provider()` 等创建逻辑。
|
||||
|
||||
**验证**：
|
||||
- `cargo test --features "full"` 仍 427 passed
|
||||
- `cargo test --no-default-features --features "llm,llm-types" --lib` 编译通过（无需任何 provider feature）
|
||||
- 所有 12 个内部文件 + 4 个示例文件的 import 路径正确
|
||||
|
||||
#### 工作 1 — examples required-features 标注
|
||||
|
||||
**设计方案**：在 `Cargo.toml` 中为每个 example 添加 `[[example]]` + `required-features`，精确到最小 features 集合。
|
||||
|
||||
```
|
||||
上下文 slot 示例（context_slot_demo）：
|
||||
工作 0 后仅需 ["agent"]（修正前需 ["agent", "provider-openai"]）
|
||||
因为 agent 的测试无需真实 provider，mock 即可
|
||||
|
||||
推理不变的 example（simple_visit）：
|
||||
真正调用 LLM，需要 ["llm", "provider-openai", "tracing-init"]
|
||||
```
|
||||
|
||||
完整映射关系见实施计划 §4.2。
|
||||
|
||||
#### 工作 2 — CI 配置
|
||||
|
||||
**设计方案**：GitHub Actions 矩阵策略，7 个并行测试 job + 1 clippy + 1 format + 1 example 验证。
|
||||
|
||||
| Job | Command | 作用域 |
|
||||
|-----|---------|--------|
|
||||
| full | `RUSTFLAGS="-D warnings" cargo test --features "full" --lib` | 全量回归，零警告 |
|
||||
| light | `RUSTFLAGS="-D warnings" cargo test --no-default-features --features "light" --lib` | 生产常用，零警告 |
|
||||
| chat | `RUSTFLAGS="-D warnings" cargo test --no-default-features --features "chat,provider-openai" --lib` | 纯对话，零警告 |
|
||||
| chat+mcp | `RUSTFLAGS="-D warnings" cargo test --no-default-features --features "chat,provider-openai,tools-mcp" --lib` | 对话 + 工具，零警告 |
|
||||
| multi | `RUSTFLAGS="-D warnings" cargo test --no-default-features --features "multi,provider-openai" --lib` | 多 Agent，零警告 |
|
||||
| multi+mcp | `RUSTFLAGS="-D warnings" cargo test --no-default-features --features "multi,provider-openai,tools-mcp" --lib` | 多 Agent + 工具，零警告 |
|
||||
| clippy | `cargo clippy --all-features --lib -- -D warnings` | lint 检查 |
|
||||
| format | `cargo fmt --check`（stable toolchain） | 格式检查 |
|
||||
| examples | `cargo test --features "full"`（不加 `--lib`，编译并运行所有 example） | example 编译验证 |
|
||||
|
||||
**关键决策**：
|
||||
- 矩阵中统一使用 `--lib` 而非 `--all-targets`。理由：examples 的编译由 `required-features` 独立管理，若混入矩阵会因 feature 组合不匹配导致 example 编译失败，干扰模块测试结果验证。
|
||||
- 使用 `RUSTFLAGS="-D warnings"` 将警告升级为编译错误，确保 `F4（0 编译器警告）`被矩阵中所有 6 个测试 job 强制执行。
|
||||
- format job 使用 stable toolchain（`cargo fmt --check` 不需要 nightly）。
|
||||
- 独立 `examples` job 使用 `cargo test --features "full"`（不加 `--lib`），验证所有 example 在完整 features 下编译并运行通过。
|
||||
|
||||
#### 工作 3 — bundle() 死代码警告修复
|
||||
|
||||
**设计方案**：在 `src/agent/session.rs:154` 的 `pub(crate) fn bundle()` 方法上添加 `#[cfg(feature = "engine")]` 条件编译。
|
||||
|
||||
背景：`bundle()` 仅被 `engine/session_manager.rs:219` 调用，当启用 `chat` 组合（agent 但非 engine）时产生 dead_code 警告。
|
||||
|
||||
**验证**：`cargo test --no-default-features --features "chat,provider-openai" --lib` 0 warnings。
|
||||
|
||||
#### 工作 4（可选）— 编译时间基线
|
||||
|
||||
记录但不沉淀到代码或 CI 中，仅供性能参考：
|
||||
```bash
|
||||
time cargo build --features "full"
|
||||
time cargo build --no-default-features --features "light"
|
||||
```
|
||||
|
||||
注：此工作在 v0.3.2 发布前为手动执行，不纳入 CI 或验收标准。若后续版本需要编译时间回归检测，可将其提升为正式工作项。
|
||||
|
||||
#### 工作 5 — 文档更新
|
||||
|
||||
三处并行更新：
|
||||

||||
**README.md 新增 features 表格**：
|
||||
- 4 个快捷组合 + 推荐使用场景 + `Cargo.toml` 配置示例
|
||||
- 下游用户可快速选择并复制配置
|
||||
|
||||
**升级指南章节（README.md 新增）**：
|
||||
- 针对工作 0 的 Breaking Change 提供迁移说明
|
||||
- 列出旧路径 → 新路径的对照表
|
||||
- 提供向后兼容的重导出方案说明
|
||||
- 示例：`agcore::llm::provider::LlmProvider` → `agcore::llm::LlmProvider`
|
||||
- 提醒用户更新 `use` 声明
|
||||
|
||||
**example 文件顶部注释**：
|
||||
- 每个 example 第一行格式：`// Required features: cargo run --example xxx --features "..."`
|
||||
- 对应工作 1 的 `required-features` 声明
|
||||
|
||||
**roadmap 状态同步**：
|
||||
- `docs/roadmap.md`：补充 Phase 26-27 完成状态 + v0.3.2 链接
|
||||
- `docs/roadmap-v0.3.2.md`：Phase 26/27 状态从 ⏳ 改为 ✅ + 完成日期
|
||||
|
||||
### 3.3 ADR 记录
|
||||
|
||||
#### ADR-1：LlmProvider trait 及关联类型归属 llm 模块
|
||||
|
||||
| 字段 | 内容 |
|
||||
|------|------|
|
||||
| 问题 | `LlmProvider` trait 定义在 provider 模块门控 `any(provider-openai, provider-anthropic, ...)` 下，纯 Mock 场景被迫引入至少一个 provider feature。其返回类型 `ProviderCapabilities` / `ProviderFeatures` 同样被困在 provider 门控中 |
|
||||
| 决策 | 将 trait 定义 + `ProviderCapabilities` / `ProviderFeatures` 一并提取到 `src/llm/provider_trait.rs`，归属 `#[cfg(feature = "llm")]` |
|
||||
| 备选方案 | 保持不动，在 mock provider 上添加 cfg 绕过 — 否决，因为 provider 模块整体门控错误 |
|
||||
| 理由 | trait 本身是个接口定义，不依赖 reqwest 或任何 provider 实现细节；`ProviderCapabilities` / `ProviderFeatures` 是 trait 方法的返回类型，必须与 trait 同门控 |
|
||||
| 影响 | 修改 6 个源文件 + 1 个新建文件 + 4 个示例文件（详见 §3.2 import 调整清单） |
|
||||
| 状态 | 已采纳 |
|
||||
|
||||
#### ADR-2：CI 使用 nightly toolchain
|
||||
|
||||
| 字段 | 内容 |
|
||||
|------|------|
|
||||
| 问题 | 项目已使用 edition 2024，是否降级到 2021 以使用 stable Rust |
|
||||
| 决策 | 测试和 clippy 使用 nightly（edition 2024 目前要求 nightly）；format 使用 stable |
|
||||
| 备选方案 | 降级 edition 到 2021 — 否决，已迁移至 edition 2024 且编译通过 |
|
||||
| 理由 | edtion 2024 是主动选择的方向，降级是倒退且涉及大量语法变更；`cargo fmt --check` 无需 nightly |
|
||||
| 影响 | CI 依赖 `actions-rust-lang/setup-rust-toolchain@v1`；format job 指定 `toolchain: stable` |
|
||||
| 状态 | 已采纳 |
|
||||
|
||||
#### ADR-3：CI 矩阵使用 `--lib` 而非 `--all-targets`
|
||||
|
||||
| 字段 | 内容 |
|
||||
|------|------|
|
||||
| 问题 | `cargo test --all-targets` 会编译所有 example，与矩阵中自选的 feature 组合可能冲突 |
|
||||
| 决策 | 矩阵测试使用 `--lib`，examples 由独立 job（`cargo test --features "full"` 不加 `--lib`）验证 |
|
||||
| 备选方案 | 在矩阵中也传入 `--all-targets` — 否决，example 编译失败会干扰模块测试验证 |
|
||||
| 理由 | 分离关注点：矩阵验证模块级编译 + 零警告，独立 job 验证 example 编译 |
|
||||
| 状态 | 已采纳 |
|
||||
|
||||
## 4. 实施计划
|
||||
|
||||
### 4.1 任务拆解与优先级
|
||||
|
||||
| 优先级 | 工作 | 编号 | 规模 | 依赖 |
|
||||

|
||||
| P1 | 文档更新 | 工作 5 | ~150 行 | 全部 |
|
||||
| P2 | 编译时间基线 | 工作 4 | 手动 | 全部 |
|
||||
|
||||
### 4.2 各 example 的 required-features 清单
|
||||
|
||||
| example 文件名 | required-features | 运行环境备注 |
|
||||
|---------------|-------------------|------------|

|
||||
| `context_slot_demo` | `["agent"]` | 工作 0 后无需 provider |
|
||||

|
||||
| `end_to_end` | `["agent", "memory-sqlite", "provider-openai"]` | 需要 API key + sqlite 依赖 |
|
||||
|
||||
**验证策略**：每个 example 除 `--lib` 验证外，还需单独运行以下命令确认 required-features 精确性：
|
||||
```bash
|
||||
cargo test --no-default-features --features "<features>" --example <name>
|
||||
```
|
||||
|
||||
### 4.3 Commit 策略
|
||||
|
||||
每个工作独立 commit，按依赖顺序排列：
|
||||
|
||||
| 顺序 | Scope | Type | 描述 | 依赖 |
|
||||
|------|-------|------|------|------|
|
||||
| 1 | `core` | `refactor` | 将 LlmProvider trait 及关联类型移出 provider 模块归属 llm | 无 |
|
||||
| 2 | `agent` | `fix` | 为 session.rs bundle() 方法添加 engine feature 门控 | 无 |
|
||||
| 3 | `examples` | `chore` | 为 18 个 example 添加 required-features 声明 | 工作 1（context_slot 等受益于工作 0 的轻量 features） |
|
||||
| 4 | `ci` | `chore` | 创建 CI 测试矩阵配置 | 无 |
|
||||
| 5 | `docs` | `docs` | 更新 README feature 表 + 升级指南 + 示例注释 + roadmap 状态 | 全部 |

# Phase 28-30 — OpenAI Response API Provider 实施方案
|
||||
|
||||
> **版本**：v1 | **作者**：Writer Agent | **日期**：2026-07-20
|
||||
>
|
||||
> **阅读前提**：本文档假设读者已熟悉现有的 Provider 实现模式（`AnthropicProvider` 独立实现方式）、IR 类型系统（`MessageRequest` / `MessageResponse` / `ContentBlock` / `StreamEvent` / `LlmProvider trait`）以及 Cargo features 门控机制。
|
||||
>
|
||||
> **前置条件**：v0.3.2（Phase 20-27）已发布，Cargo features 拆分完成，CI 矩阵 6 种组合全部通过。
|

|
||||
|
||||
## 1. 背景与目标
|
||||
|
||||
### 1.1 背景
|
||||
|
||||
OpenAI 于 2025 年下半年发布了 **Response API**（`POST /responses`），作为 Chat Completions API（`POST /chat/completions`）的下一代接口。Response API 不仅提供了更简洁的请求/响应结构，还将 `web_search`、`file_search`、`computer_use` 等内置工具提升为一等公民，并引入了 `previous_response_id` 多轮续写等新机制。
|
||||
|
||||
agcore 当前通过 `GenericOpenaiProvider` 实现了 OpenAI Chat Completions 协议。`ProviderType::OpenaiResponse` 枚举项已在 `src/llm/provider.rs` 中定义，但工厂函数返回 `Err("Phase 1 暂不实现；请使用 OpenaiChat")`。
|
||||
|
||||
### 1.2 目标
|
||||
|
||||
- 实现独立的 `OpenaiResponseProvider`（不套用 `GenericOpenaiProvider`，参考 `AnthropicProvider` 模式）
|
||||
- 覆盖 Response API 的核心能力：文本对话、流式输出、Vision 输入、工具调用（function calling）
|
||||
- 新增独立 feature `provider-openai-response`，加入 `full` 快捷组合
|
||||
- 内置工具（`web_search` / `file_search` / `computer_use`）通过 `MessageRequest.extra` 逃生舱传递
|
||||
- 多轮接续第一版走全量消息历史模式
|
||||
|
||||
### 1.3 范围
|
||||
|
||||
| 维度 | 包含 | 不包含 |
|
||||
|------|------|--------|
|
||||
| 协议端点 | `POST /responses` | `/responses/{id}/input_items` 等管理端点 |
|
||||
| 输入模式 | 全量消息历史 + `previous_response_id` | 增量续写优化 |
|
||||
| 内置工具 | 通过 `extra` 逃生舱透传 | 原生 ToolDef 结构改动 |
|
||||
| 流式 | SSE 语义事件 → `StreamEvent` | — |
|
||||
| 结构化输出 | `text.format` | 暂不专项封装 |
|
||||
|
||||
---
|
||||
|
||||
## 2. 需求分析
|
||||
|
||||
### 2.1 功能需求
|
||||
|
||||
| # | 需求 | 优先级 | 说明 |
|
||||
|---|------|--------|------|
|
||||
| F1 | 文本对话（非流式 + 流式） | P0 | 最基础的对话能力 |
|
||||
| F2 | Vision 图片输入 | P0 | `UserImage` → `input_image` |
|
||||
| F3 | Function Calling 工具调用 | P0 | `ToolDef` → `{type: "function", ...}` |
|
||||
| F4 | 多轮接续 | P1 | 全量消息历史模式 |
|
||||
| F5 | System 消息处理 | P0 | 多个 System 消息拼接到 `instructions` |
|
||||
| F6 | 流式 SSE 事件映射 | P0 | 按 Response API SSE 事件序列映射 |
|
||||
| F7 | 内置工具逃生舱 | P2 | `extra` 字段透传 `web_search` / `file_search` |
|
||||
| F8 | 结构化输出逃生舱 | P2 | `extra` 字段透传 `text.format` |
|
||||
|
||||
### 2.2 非功能需求
|
||||
|
||||
| # | 需求 | 指标 |
|
||||
|---|------|------|
|
||||
| N1 | 编译隔离 | 新增 feature 不增加 `light` / `chat` 组合的依赖 |
|
||||
| N2 | 测试覆盖 | wiremock 覆盖非流式 + 流式 + 错误路径 |
|
||||
| N3 | 错误映射 | 复用 `GenericOpenaiProvider` 的错误映射逻辑 |
|
||||
| N4 | Clippy 合规 | `cargo clippy --all-features --lib -- -D warnings` 通过 |
|
||||
|
||||
### 2.3 与 Chat Completions 的差异回顾
|
||||
|
||||
| 维度 | Chat Completions | Response API |
|
||||
|------|-----------------|--------------|
|
||||
| 端点 | `POST /chat/completions` | `POST /responses` |
|
||||
| 输入 | `messages: [{role, content}]` | `input: string \| items[]` + 顶层 `instructions` |
|
||||
| 输出 | `choices[n].message` | `output: []` 异构 items 数组 |
|
||||
| 内置工具 | 无（仅 function calling） | `web_search` / `file_search` / `computer_use` 一等公民 |
|
||||
| 多轮接续 | 调用方拼接 messages | `previous_response_id` 参数 或 全量回传 |
|
||||
| 流式 | SSE chunk `choices[n].delta` | SSE 语义事件：`response.text.delta` / `response.output_item.added` 等 |
|
||||
| 结构化输出 | `response_format` | `text.format` |
|
||||
| 认证 | `Authorization: Bearer` | 相同 |
|
||||
| 错误结构 | 相同（401/429/500） | 相同 |
|
||||
|
||||

|
||||
|
||||
## 3. 方案设计
|
||||
|
||||
### 3.1 设计决策
|
||||
|
||||
| # | 决策 | 选项 | 选择 | 理由 |
|
||||
|---|------|------|------|------|
|
||||
| D1 | 实现方式 | 独立 Provider vs 套用 GenericOpenaiProvider | **独立 Provider** | Response API 请求/响应结构与 Chat Completions 差异过大，序列化/反序列化无共用价值 |
|
||||
| D2 | Feature 粒度 | 合并到 `provider-openai` vs 独立 | **独立 feature** | 与 `AnthropicProvider` 对齐，避免 `full` 组合膨胀 |
|
||||
| D3 | 加入快捷组合 | 加入 `full` 但不加入 `light` | **`full` 包含** | Response API 属于高级能力，`light` 保持轻量 |
|
||||
| D4 | 多轮方案 | 全量历史 vs 增量 | **全量历史（模式 A）** | 功能正确，无需改动 `LlmCycle` |
|
||||
| D5 | 内置工具支持 | 改 ToolDef vs extra 逃生舱 | **extra 逃生舱** | 不改已有 IR 类型，最小侵入 |
|
||||
|
||||
### 3.2 Feature 定义
|
||||
|
||||
```toml
|
||||
provider-openai-response = ["llm", "reqwest", "bytes", "futures-util"]
|
||||
```
|
||||
|
||||
与 `provider-openai` / `provider-anthropic` 的依赖集合一致——`llm` 已包含 `tokio` / `async-stream` / `futures-core` / `futures-util` / `tokio-stream`，此处补充 `reqwest`（HTTP 客户端）和 `bytes`（流式 buffer 操作）。
|
||||
|
||||
`full` 快捷组合追加 `"provider-openai-response"`。
|
||||
|
||||
### 3.3 新增文件
|
||||
|
||||
所有实现集中在单一文件：
|
||||
|
||||
```
|
||||
src/llm/provider/openai_response.rs ← 全部实现（Wire 类型 + Provider 结构体 + 请求转换 + 响应转换 + 流式处理 + 测试）
|
||||
```
|
||||
|
||||
不在 `provider/` 下创建子目录。模块声明在 `src/llm.rs`，在现有 Provider features cfg 条件中追加 `feature = "provider-openai-response"`：
|
||||
|
||||
```rust
|
||||
#[cfg(any(
|
||||
feature = "provider-openai",
|
||||
feature = "provider-anthropic",
|
||||
feature = "provider-deepseek",
|
||||
feature = "provider-qwen",
|
||||
feature = "provider-ollama",
|
||||
feature = "provider-openai-response",
|
||||
))]
|
||||
pub mod provider;
|
||||
```
|
||||
|
||||
### 3.4 架构概览

> **关于 `ResponseInputItem` 与 `ResponseOutputItem` 的职责划分**：
|
||||
>
|
||||
> - **`ResponseInputItem`**（`#[serde(untagged)]`）：仅用于**请求序列化**（`convert_request`），由代码控制枚举变体的生成，永远不会遇到未知的 `item_type`。因此 untagged 模式是安全的，无需 fallback。
|
||||
> - **`ResponseOutputItem`**（非 untagged，`item_type: String` 为必填字段）：用于**响应反序列化**（`convert_response`），来自 API 响应。未知的 `item_type` 已通过 §3.7 的 `ContentBlock::Extension` fallback 处理，不会因新增 item 类型而触发 serde 反序列化失败。

### 3.6 请求转换（convert_request）
|
||||
|
||||
#### 消息类型映射
|
||||
|
||||
| 输入场景 | Message 类型 | → Response API input item |
|
||||
|---------|-------------|--------------------------|
|
||||
| 文本 User | `Message::User { content: [Text] }` | `{role: "user", content: [{type: "input_text", text}]}` |
|
||||
| Vision | `Message::UserImage { data, mime_type, detail }` | `{role: "user", content: [{type: "input_image", image_url: "data:{mime};base64,{data}", detail}]}` |
|
||||
| User 多模态 | `Message::User { content: [Text, Image, ...] }` | `{role: "user", content: [{type: "input_text", text}, {type: "input_image", image_url, detail}]}` |
|
||||
| Assistant 文本 | `Message::Assistant { content: [Text] }` | User 侧：`{role: "assistant", content: [{type: "output_text", text}]}`（无 `type` 字段）；回传时: `{type: "message", role: "assistant", content: [{type: "output_text", text}]}`（有 `type: "message"`） |
|
||||
| Assistant 工具调用 | `Message::Assistant { content: [ToolUse] }` | `FunctionCall { call_id, name, arguments }` |
|
||||
| Assistant 文本+工具 | `Message::Assistant { content: [Text, ToolUse, ...] }` | 一个 `Message(assistant)` + 一个或多个 `FunctionCall` 项 |
|
||||
| 工具结果 | `Message::ToolResult { tool_call_id, content, is_error }` | `FunctionCallOutput { call_id, output: content }` |
|
||||
| System | `Message::System { content }` | 拼接到顶层 `instructions` 字段（非 input） |
|
||||
|
||||
#### 字段映射
|
||||
|
||||
| MessageRequest 字段 | → Response API 字段 |
|
||||
|---------------------|---------------------|
|
||||
| `model` | `model` |
|
||||
| `max_tokens` | `max_output_tokens` |
|
||||
| `temperature` | `temperature` |
|
||||
| `top_p` | `top_p` |
|
||||
| `stop_sequences` | `stop` |
|
||||
| `stream` | `stream` |
|
||||
| `tools` (ToolDef) | `tools` = `[{type: "function", name, description, parameters}]` |
|
||||
| `tool_choice` | `tool_choice` |
|
||||
|
||||
#### extra 字段映射
|
||||
|
||||
| `MessageRequest.extra` key | → Response API 字段 |
|
||||
|---------------------------|---------------------|
|
||||
| `previous_response_id` | `previous_response_id` |
|
||||
| `store` | `store` |
|
||||
| `metadata` | `metadata` |
|
||||
| `truncation` | `truncation` |
|
||||
| `reasoning.effort` | `reasoning: {effort: ...}` |
|
||||
| 内置工具（`web_search` / `file_search` 等） | 追加到 `tools` 数组 |
|
||||
|
||||
> **备注**：当前仅支持 `reasoning.effort` 子字段（值为 `low`/`medium`/`high`），其他子字段（如 `reasoning.summary`）将在后续版本支持。
|
||||
|
||||
### 3.7 响应转换（convert_response）
|
||||
|
||||
| Response API output item | → MessageResponse 中的表示 |
|
||||
|-------------------------|------------------------------|
|
||||
| `{type: "message", role: "assistant", content: [{type: "output_text", text}]}` | `Message::Assistant { content: [ContentBlock::Text { text }] }` |
|
||||
| `{type: "function_call", name, arguments, call_id}` | `ContentBlock::ToolUse { id: call_id, name, input: arguments }` |
|
||||
| `{type: "web_search_call", ...}` | `ContentBlock::Extension { kind: "web_search_call", data: ... }` |
|
||||
| `{type: "reasoning", ...}` | `ContentBlock::Extension { kind: "reasoning", data: ... }` |
|
||||
| `{type: "file_search_call", ...}` | `ContentBlock::Extension { kind: "file_search_call", data: ... }` |
|
||||
|
||||
**status → StopReason 映射**：
|
||||
- `completed` → `StopReason::Stop`
|
||||
- `incomplete` → `StopReason::Length`
|
||||
- `failed` → `StopReason::Other`
|
||||
|
||||
当 `response.output` 为空数组时，返回 `LlmError::Request { status: 200, body: "empty output" }`，表示响应格式异常。
|
||||
|
||||
对于未知的 `item_type`（非 `message`/`function_call`/`web_search_call`/`file_search_call`/`reasoning`），转换为 `ContentBlock::Extension { kind: item_type, data: serde_json::to_value(item)? }` 以保持前向兼容。
|
||||
|
||||
### 3.8 流式 SSE 事件映射
|
||||
|
||||
| Response API SSE event | → StreamEvent |
|
||||
|------------------------|---------------|
|
||||
| `response.created` | `MessageStart { id, model }` |
|
||||
| `response.output_item.added` (type: message) | `ContentBlockStart { index, block_type: Text }` |
|
||||
| `response.output_text.delta` | `TextDelta { text }` |
|
||||
| `response.output_text.done` | `ContentBlockEnd { index }` |
|
||||
| `response.refusal.delta` | `RefusalDelta { text }` |
|
||||
| `response.refusal.done` | `ContentBlockEnd { index }` |
|
||||
| `response.function_call_arguments.delta` | `ToolCallArgumentsDelta { index, arguments }` |
|
||||
| `response.function_call_arguments.done` | `ToolCallEnd { index }` |
|
||||
| `response.completed` | `MessageComplete { full_response }` |
|
||||
| `response.failed` | `Error { message }` |
|
||||
|
||||
### 3.9 流式 SSE 状态机
|
||||
|
||||
`ResponseSseEventStream` 维护以下状态：
|
||||
|
||||
```
|
||||
字段：
|
||||
- byte_stream: reqwest 的 bytes_stream
|
||||
- buffer: Vec<u8>（SSE 行缓冲）
|
||||
- partial: PartialMessageResponse（累积响应状态）
|
||||
- block_index: u32（输出 block 序号计数器）
|
||||
- saw_terminal: bool（是否已见到 response.completed / response.failed）
|
||||
|
||||
流程：
|
||||
line 级解析 → event: + data: 配对
|
||||
→ 反序列化 ResponseSseEvent
|
||||
→ try_into_stream_event() 映射为 StreamEvent
|
||||
→ StreamEvent::apply_to(&mut partial)
|
||||
→ yield StreamEvent
|
||||
response.completed → partial.finalize() → yield MessageComplete
|
||||
response.failed → yield Error
|
||||
```
|
||||
|
||||
### 3.10 错误映射
|
||||
|
||||
复用 `GenericOpenaiProvider` 的 `handle_error_response()` 逻辑：
|
||||
|
||||
| HTTP 状态码 | → LlmError |
|
||||
|------------|------------|
|
||||
| 401 | `LlmError::Authentication(body)` |
|
||||
| 429 | `LlmError::RateLimit { retry_after }` |
|
||||
| 5xx | `LlmError::Request { status, body }` |
|
||||
| 400 + `context_length_exceeded` | `LlmError::ContextLength` |
|
||||
|
||||
### 3.11 Provider 结构体
|
||||
|
||||
```rust
|
||||
pub(crate) struct OpenaiResponseProvider {
|
||||
http_client: Client,
|
||||
base_url: String,
|
||||
api_key: String,
|
||||
model: String,
|
||||
timeout_secs: u64,
|
||||
}
|
||||
```
|
||||
|
||||
#### 工厂方法
|
||||
|
||||
```rust
|
||||
impl OpenaiResponseProvider {
|
||||
pub(crate) fn from_parts(
|
||||
base_url: String,
|
||||
api_key: String,
|
||||
model: String,
|
||||
http_client: Client,
|
||||
timeout_secs: u64,
|
||||
) -> Self {
|
||||
Self { http_client, base_url, api_key, model, timeout_secs }
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3.12 LlmProvider trait 实现
|
||||
|
||||
```rust
|
||||
#[async_trait]
|
||||
impl LlmProvider for OpenaiResponseProvider {
|
||||
async fn chat(&self, request: MessageRequest) -> Result<MessageResponse, LlmError> {
|
||||
self.chat_blocking(request).await
|
||||
}
|
||||
|
||||
async fn chat_stream(
|
||||
&self,
|
||||
request: MessageRequest,
|
||||
) -> Result<Pin<Box<dyn Stream<Item = Result<StreamEvent, LlmError>> + Send>>, LlmError> {
|
||||
self.chat_stream_inner(request).await
|
||||
}
|
||||
|
||||
fn capabilities(&self) -> ProviderCapabilities { ... }
|
||||
}
|
||||
```
|
||||
|
||||
### 3.13 Capabilities
|
||||
|
||||
```rust
|
||||
ProviderCapabilities {
|
||||
provider_name: "openai-response",
|
||||
supported_models: Some(vec![model]),
|
||||
features: ProviderFeatures {
|
||||
streaming: true,
|
||||
thinking: true, // o-series reasoning
|
||||
vision: true, // image input
|
||||
audio_input: false,
|
||||
tool_use: true,
|
||||
parallel_tool_calls: true,
|
||||
system_prompt_in_messages: false,
|
||||
max_context_window: 200_000,
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
### 3.14 工厂函数注册
|
||||
|
||||
```rust
|
||||
ProviderType::OpenaiResponse => {
|
||||
let client = build_client_with_timeout(config.timeout_secs)?;
|
||||
Ok(Box::new(openai_response::OpenaiResponseProvider::from_parts(
|
||||
config.base_url,
|
||||
config.api_key,
|
||||
config.model,
|
||||
client,
|
||||
config.timeout_secs,
|
||||
)))
|
||||
}
|
||||
```
|
||||
|
||||
### 3.15 多轮接续方案
|
||||
|
||||
第一版走**全量消息历史模式（模式 A）**：
|
||||
|
||||
1. `convert_request()` 把 `MessageRequest.messages` 全部转换为 `input` items
|
||||
2. System 消息拼接到 `instructions`
|
||||
3. User / Assistant / ToolResult 消息转换为对应的 input items
|
||||
4. 如果 `extra` 中有 `previous_response_id`，也传入请求体
|
||||
|
||||
此模式与 `LlmCycle::submit_with_tools()` 完全兼容——`LlmCycle` 在每次提交时都会填充完整的历史 messages，`OpenaiResponseProvider` 只是把这些 messages 全部序列化为 Response API 格式。无需改动 `LlmCycle`。
|
||||
|
||||
---
|
||||
|
||||
## 4. 实施计划
|
||||
|
||||
实施拆分为 3 个 Phase，9 个 Step。
|
||||
|
||||
### Phase 28：Feature gate + Wire 类型 + Provider 骨架（~140 行）
|
||||
|
||||
#### Step 28.1：Cargo.toml feature 定义
|
||||
**文件操作**：修改 `Cargo.toml`
|
||||
|
||||
```toml
|
||||
# 在 [features] 的 Provider features 区域追加
|
||||
provider-openai-response = ["llm", "reqwest", "bytes", "futures-util"]
|
||||
|
||||
# 在 full 快捷组合中追加
|
||||
full = [
|
||||
"...",
|
||||
"provider-openai-response",
|
||||
]
|
||||
```
|
||||
|
||||
**验证**：`cargo build --features "provider-openai-response"` 编译通过
|
||||
|
||||
#### Step 28.2：Wire 类型定义
|
||||
**文件操作**：新建 `src/llm/provider/openai_response.rs`
|
||||
|
||||
定义 §3.5 中的所有 Wire 类型：
|
||||
- `OpenaiResponseRequest`
|
||||
- `ResponseInputItem`（untagged 枚举：Message / FunctionCall / FunctionCallOutput）
|
||||
- `ResponseInputContent`（tagged 枚举：InputText / InputImage）
|
||||
- `ResponseTool`
|
||||
- `OpenaiResponseBody`
|
||||
- `ResponseOutputItem`
|
||||
- `ResponseContentPart`
|
||||
- `ResponseSseEvent`（完整时序事件枚举）
|
||||
- `ResponseSseMeta`
|
||||
|
||||
**无逻辑代码**，只有 `#[derive(Debug, Clone, Serialize, Deserialize)]` 的结构体和枚举。
|
||||
|
||||
**验证**：`cargo build --features "provider-openai-response"` 编译通过
|
||||
|
||||
#### Step 28.3：Provider 结构体 + from_parts
|
||||
**文件操作**：追加到 `src/llm/provider/openai_response.rs`
|
||||
|
||||
- `OpenaiResponseProvider` 结构体
|
||||
- `from_parts()` 工厂方法
|
||||
- 基础 HTTP 工具函数（`build_request_builder`、`handle_error_response`、`map_reqwest_error`）
|
||||
|
||||
**验证**：`cargo build --features "provider-openai-response"` 编译通过
|
||||
|
||||
#### Step 28.4：Factory 注册 + 模块门控
|
||||
**文件操作**：
|
||||
1. 修改 `src/llm.rs` — 在 cfg 条件中追加 `feature = "provider-openai-response"`
|
||||
2. 修改 `src/llm/provider.rs` — 注册 factory
|
||||
|
||||
在 `src/llm.rs` 中修改现有 Provider features cfg 条件：
|
||||
|
||||
```rust
|
||||
#[cfg(any(
|
||||
feature = "provider-openai",
|
||||
feature = "provider-anthropic",
|
||||
feature = "provider-deepseek",
|
||||
feature = "provider-qwen",
|
||||
feature = "provider-ollama",
|
||||
feature = "provider-openai-response",
|
||||
))]
|
||||
pub mod provider;
|
||||
```
|
||||
|
||||
以及在 `src/llm/provider.rs` 的 `create_provider()` match 中替换当前 `Err` 为真实构造。
|
||||
|
||||
**验证**：
|
||||
- `cargo build --features "provider-openai-response"` 编译通过
|
||||
- `cargo build --features "full"` 编译通过
|
||||
|
||||
---
|
||||
|
||||
### Phase 29：核心 Provider 实现（~680 行）
|
||||
|
||||
#### Step 29.1：convert_request（~200 行）
|
||||
**文件操作**：追加到 `src/llm/provider/openai_response.rs`
|
||||
|
||||
实现 `OpenaiResponseProvider::convert_request(&self, request: MessageRequest) -> Result<OpenaiResponseRequest, LlmError>`。
|
||||
|
||||
处理逻辑：
|
||||
1. 遍历 `request.messages`，按 §3.6 消息类型映射表转换
|
||||
2. Assistant 消息回传时设置 `item_type: Some("message".to_string())`，使序列化结果为 `{type: "message", role: "assistant", content: [...]}`；User 消息保持 `item_type: None`，序列化为 `{role: "user", content: [...]}`（无 `type` 字段）
|
||||
3. `request.tools` → `tools` 数组（`ToolDef` → `ResponseTool::Function`）
|
||||
4. `request.extra` → 解析 `previous_response_id` / `store` / `metadata` / `truncation` / `reasoning` 等
|
||||
5. 标准字段映射（model / max_tokens / temperature / top_p / stop / stream）
|
||||
|
||||
#### Step 29.2：convert_response（~100 行）
|
||||
**文件操作**：追加到 `src/llm/provider/openai_response.rs`
|
||||
|
||||
实现 `OpenaiResponseProvider::convert_response(&self, response: OpenaiResponseBody) -> Result<MessageResponse, LlmError>`。
|
||||
|
||||
处理逻辑：
|
||||
1. 遍历 `response.output`，找到第一个 `type: "message"` 的 item，提取 text
|
||||
2. 其他 items（`function_call` → `ContentBlock::ToolUse`，内置工具 → `ContentBlock::Extension`）
|
||||
3. `response.status` → `StopReason`
|
||||
4. `response.usage` → `Usage`
|
||||
|
||||
#### Step 29.3：非流式 chat()（~80 行）
|
||||
**文件操作**：追加到 `src/llm/provider/openai_response.rs`
|
||||
|
||||
实现 `OpenaiResponseProvider::chat_blocking()`：
|
||||
- `convert_request()` → serde 序列化 → HTTP POST `{base_url}/responses`
|
||||
- Auth header: `Authorization: Bearer {api_key}`
|
||||
- 错误处理映射
|
||||
- 解析响应体 → `convert_response()`
|
||||
|
||||
#### Step 29.4：SSE 事件类型 + 状态机（~230 行）
|
||||
**文件操作**：追加到 `src/llm/provider/openai_response.rs`
|
||||
|
||||
实现 `ResponseSseEventStream` 结构体及其 `Stream` trait：
|
||||
- 字段：`byte_stream`, `buffer`, `partial: PartialMessageResponse`, `block_index: u32`, `saw_terminal: bool`
|
||||
- 行级 SSE 解析：`event:` + `data:` 配对
|
||||
- 事件 → `StreamEvent` 映射
|
||||
- `PartialMessageResponse::apply_to()` 累积
|
||||
- 流结束时 `finalize()` → `MessageComplete`
|
||||
|
||||
#### Step 29.5：流式 chat_stream()（~50 行）
|
||||
**文件操作**：追加到 `src/llm/provider/openai_response.rs`
|
||||
|
||||
实现 `OpenaiResponseProvider::chat_stream_inner()`：
|
||||
- `convert_request()` 设置 `stream: true`
|
||||
- HTTP POST → bytes_stream → 包装为 `ResponseSseEventStream`
|
||||
|
||||
#### Step 29.6：LlmProvider impl（~50 行）
|
||||
**文件操作**：追加到 `src/llm/provider/openai_response.rs`
|
||||
|
||||
实现 `LlmProvider for OpenaiResponseProvider`：
|
||||
- `chat()` → `chat_blocking()`
|
||||
- `chat_stream()` → `chat_stream_inner()`
|
||||
- `capabilities()` → 返回 `ProviderCapabilities`
|
||||
|
||||
#### Step 29.7：单元测试（~70 行）
|
||||
**文件操作**：追加到 `src/llm/provider/openai_response.rs` 的 `#[cfg(test)] mod tests {}`
|
||||
|
||||
| 测试 | 场景 |
|
||||
|------|------|
|
||||
| `convert_request_text_only` | 纯文本输入转换 |
|
||||
| `convert_request_vision` | Vision 输入转换 |
|
||||
| `convert_request_tool_call` | 工具调用输入转换 |
|
||||
| `convert_response_message` | 响应 message item 转换 |
|
||||
| `convert_response_tool_use` | 响应 function_call item 转换 |
|
||||
|
||||

|
||||
|
||||
### Phase 30：测试 + CI + 文档（~520 行）
|
||||
|
||||
#### Step 30.1：wiremock 非流式测试（~200 行）
|
||||

| `response_api_tool_call` | 工具调用 | `stop_reason == ToolUse` |
|
||||
| `response_api_multi_turn` | 两轮对话 | 第二轮携带历史 |
|

| `response_api_rate_limit` | 429 错误 | `LlmError::RateLimit` |
|
||||
| `response_api_server_error` | 500 错误 | `LlmError::Request` |
|
||||
|

# OpenAI Response Provider 自定义请求头支持
|
||||
|
||||
## 背景
|
||||
|
||||
OpenAI Responses API 的部分实现（如火山引擎豆包）需要携带特殊的 HTTP 请求头（如 `ark-beta-doubao-app: true`）来启用平台特定功能。当前 `OpenaiResponseProvider` 在 `build_request_builder()` 中只设置了 `Authorization` 头，没有途径注入自定义请求头。
|
||||
|
||||
原方案只覆盖 OpenAI Response Provider。经讨论后扩展为**三 Provider 统一**方案：OpenAI Chat（`GenericOpenaiProvider`）、OpenAI Response（`OpenaiResponseProvider`）、Anthropic（`AnthropicProvider`）。
|
||||
|
||||
核心动机：
|
||||
|
||||
- OpenAI Responses API 的部分实现需要携带特殊 HTTP 请求头来启用平台特定功能
|
||||
- 三种基础协议中，自定义头注入能力不一致
|
||||
- 统一 API 让调用方用 `set_extra("custom_headers", ...)` 即可，与底层协议无关
|
||||
|
||||
## 需求
|
||||
|
||||
### 功能需求
|
||||
|
||||
双层自定义头机制：
|
||||
|
||||
- **Provider 级固定头**：`extra_headers: Vec<(String, String)>`，构造时注入，所有请求自动携带。用于该 provider 所有请求都需要的固定标识头（如平台接入标记）
|
||||
- **请求级临时头**：`extra.custom_headers: HashMap<String, String>`，通过 `set_extra` 注入。用于特定请求需要覆盖或追加的头
|
||||
|
||||
### 约束
|
||||
|
||||
- 不可引入任何平台特定逻辑（火山、豆包等字符串不得出现）
|
||||
- 自定义头仅运行时生效，不进入 JSON 序列化的请求体
|
||||
- 兼容已有的 extra 逃生舱机制（builtin_tools、text_format 等）
|
||||
- agcore 是支持库，不提供运行时敏感头过滤保护（如 Authorization/Cookie），但文档中应说明风险
|
||||
- 不修改 `LlmProvider` trait、`ProviderType` 枚举
|
||||
- `create_provider()` 工厂函数只传 `Vec::new()` 作为 extra_headers 默认值，不暴露配置能力；调用方如需 Provider 级固定头，直接构造 provider 后链式调用 `.with_extra_headers()`
|
||||
|
||||
### 用户故事
|
||||
|
||||
1. 作为集成者，我想对任意 provider 的请求注入自定义 HTTP 头，以启用平台特有功能（请求级）
|
||||
2. 作为集成者，我想在 provider 构造时注入固定头，让所有请求自动携带，避免每次重复指定（Provider 级）
|
||||
3. 作为维护者，我想三种基础协议使用统一的 API，调用方无需关心底层 provider 类型
|
||||
|
||||
## 方案设计
|
||||
|
||||
### 统一设计原则
|
||||
|
||||
```
|
||||
调用方视角（统一 API）：
|
||||
request.set_extra("custom_headers", json!({"X-Foo": "bar"}));
|
||||
// 不管底层是 OpenAI Chat / OpenAI Response / Anthropic，都能工作
|
||||
|
||||
构造方视角（Provider 级）：
|
||||
OpenaiResponseProvider::from_parts(..., extra_headers).with_extra_headers(...);
|
||||
GenericOpenaiProvider::from_parts(..., extra_headers); // 已有
|
||||
AnthropicProvider::from_parts(..., extra_headers);
|
||||
|
||||
头融合顺序（三 provider 一致）：
|
||||
认证头 (Authorization / x-api-key) → Provider 级 extra_headers → 请求级 custom_headers
|
||||
↑ 后者覆盖前者
|
||||
```
|
||||
|
||||
### 改动一：GenericOpenaiProvider（openai.rs）
|
||||
|
||||
**① `OpenaiChatRequest` 新增字段**
|
||||
|
||||
在 `extra_body`（第 147 行）之后：
|
||||
|
||||
```rust
|
||||
/// 请求级别自定义 HTTP 头。运行时注入，不进入 JSON 请求体。
|
||||
/// ⚠️ 与 struct 已有的 `extra_headers: Option<Value>`（OpenAI API 自身的 wire 格式字段）
|
||||
/// 不同——后者是 OpenAI API 参数，本字段是 reqwest 层的 HTTP 头注入。
|
||||
#[serde(skip)]
|
||||
pub custom_headers: HashMap<String, String>,
|
||||
```
|
||||
|
||||
`#[serde(skip)]` 确保该字段不会出现在序列化后的 JSON body 中。
|
||||
|
||||
**② `convert_request()` 从 extra 提取**
|
||||
|
||||
在 `parallel_tool_calls`（第 559 行）之后：
|
||||
|
||||
```rust
|
||||
let custom_headers: HashMap<String, String> = request
|
||||
.get_extra_opt("custom_headers")
|
||||
.unwrap_or_default();
|
||||
```
|
||||
|
||||
**③ `build_request_builder()` 签名改具体类型 + 注入逻辑**
|
||||
|
||||
第 454 行，签名从 `&impl Serialize` 改为 `&OpenaiChatRequest`（两处调用点传入的均为该类型，安全）：
|
||||
|
||||
```rust
|
||||
fn build_request_builder(
|
||||
&self,
|
||||
url: &str,
|
||||
body: &OpenaiChatRequest, // 从 &impl Serialize 改为具体类型
|
||||
) -> Result<reqwest::RequestBuilder, LlmError> {
|
||||
let mut builder = self
|
||||
.http_client
|
||||
.post(url)
|
||||
.header("Authorization", format!("Bearer {}", self.api_key));
|
||||
|
||||
// 头融合顺序见上方「统一设计原则」。
|
||||
// Provider 级固定头先注入，请求级临时头后注入（后者覆盖前者）。
|
||||
|
||||
Ok(builder.json(body))
|
||||
}
|
||||
```
|
||||
|
||||
两处调用点（`chat_blocking` 第 628 行、`chat_stream_inner` 第 669 行）传入的都是 `&OpenaiChatRequest`，零影响。
|
||||
|
||||
**④ `with_extra_headers()` builder 方法**
|
||||
|
||||
```rust
|
||||
/// 注入 Provider 级别固定头。返回 self 以支持链式调用。
|
||||
pub fn with_extra_headers(mut self, headers: Vec<(String, String)>) -> Self {
|
||||
self.extra_headers = headers;
|
||||
self
|
||||
}
|
||||
```
|
||||
|
||||
### 改动二：OpenaiResponseProvider（openai_response.rs）
|
||||
|
||||
**① struct 新增 `extra_headers` 字段**
|
||||
|
||||
第 287 行，`pub struct OpenaiResponseProvider` 增加：
|
||||
|
||||
```rust
|
||||
pub struct OpenaiResponseProvider {
|
||||
// ... 已有字段 ...
|
||||
extra_headers: Vec<(String, String)>,
|
||||
}
|
||||
```
|
||||
|
||||
**② `from_parts()` 新增参数**
|
||||
|
||||
第 299 行：
|
||||
|
||||
```rust
|
||||
pub(crate) fn from_parts(
|
||||
base_url: String,
|
||||
api_key: String,
|
||||
model: String,
|
||||
http_client: Client,
|
||||
timeout_secs: u64,
|
||||
extra_headers: Vec<(String, String)>, // 新增
|
||||
) -> Self { ... }
|
||||
```
|
||||
|
||||
**③ `with_extra_headers()` builder 方法**
|
||||
|
||||
```rust
|
||||
/// 注入 Provider 级别固定头。返回 self 以支持链式调用。
|
||||
pub fn with_extra_headers(mut self, headers: Vec<(String, String)>) -> Self {
|
||||
self.extra_headers = headers;
|
||||
self
|
||||
}
|
||||
```
|
||||
|
||||
**④ `OpenaiResponseRequest` 新增字段**
|
||||
|
||||
第 73 行，`reasoning` 之后：
|
||||
|
||||
```rust
|
||||
/// 请求级别自定义 HTTP 头。序列化时跳过，仅运行时由 build_request_builder 消费。
|
||||
/// stream 模式的修改不影响该字段——header 由 convert_request 在请求构造时注入。
|
||||
#[serde(skip)]
|
||||
pub custom_headers: HashMap<String, String>,
|
||||
```
|
||||
|
||||
`#[serde(skip)]` 确保该字段不会出现在序列化后的 JSON body 中。
|
||||
|
||||
**⑤ `convert_request()` 从 extra 提取**
|
||||
|
||||
第 404 行，`reasoning` 之后：
|
||||
|
||||
```rust
|
||||
let custom_headers: HashMap<String, String> = extra
|
||||
.get("custom_headers")
|
||||
.and_then(|v| serde_json::from_value(v.clone()).ok())
|
||||
.unwrap_or_default();
|
||||
```
|
||||
|
||||
> **注意**：OpenaiResponseProvider 的 `convert_request` 在顶部 destructure 了 `request`，因此使用 `extra.get()` 而非 `request.get_extra_opt()`。两者语义一致，均反序列化为 `HashMap<String, String>`，失败时静默降级为空 HashMap。
|
||||
|
||||
**⑥ `build_request_builder()` 签名 + 注入逻辑**
|
||||
|
||||
第 319 行，签名从 `&impl Serialize` 改为 `&OpenaiResponseRequest`（两处调用点传入的均为该类型，安全）：
|
||||
|
||||
```rust
|
||||
/// 构造 HTTP POST 请求 builder（含认证头与额外请求头）。
|
||||
///
|
||||
/// 头融合顺序：Authorization → Provider 级 extra_headers → 请求级 custom_headers
|
||||
/// 后者覆盖前者。
|
||||
fn build_request_builder(
|
||||
&self,
|
||||
body: &OpenaiResponseRequest, // 从 &impl Serialize 改为具体类型
|
||||
) -> Result<reqwest::RequestBuilder, LlmError> {
|
||||
let mut builder = self
|
||||
.http_client
|
||||
.post(self.endpoint_url())
|
||||
.header("Authorization", format!("Bearer {}", self.api_key));
|
||||
|
||||
for (k, v) in &self.extra_headers {
|
||||
builder = builder.header(k.as_str(), v.as_str());
|
||||
}
|
||||
|
||||
for (key, value) in &body.custom_headers {
|
||||
builder = builder.header(key.as_str(), value.as_str());
|
||||
}
|
||||
|
||||
Ok(builder.json(body))
|
||||
}
|
||||
```
|
||||
|
||||
两处调用点（`chat_blocking` 第 708 行、`chat_stream_inner` 第 741 行）传入的都是 `&OpenaiResponseRequest`，零影响。
|
||||
|
||||
### 改动三：AnthropicProvider（anthropic.rs）
|
||||
|
||||
AnthropicProvider 是唯一没有统一 `build_request_builder` 方法的 provider，需要**前置重构**。
|
||||
|
||||
**① struct 新增 `extra_headers` 字段**
|
||||
|
||||
第 36 行：
|
||||
|
||||
```rust
|
||||
pub struct AnthropicProvider {
|
||||
// ... 已有字段 ...
|
||||
extra_headers: Vec<(String, String)>,
|
||||
}
|
||||
```
|
||||
|
||||
**② `from_parts()` 新增参数**
|
||||
|
||||
第 128 行：
|
||||
|
||||
```rust
|
||||
pub(crate) fn from_parts(
|
||||
base_url: String,
|
||||
api_key: String,
|
||||
model: String,
|
||||
http_client: Client,
|
||||
timeout_secs: u64,
|
||||
extra_headers: Vec<(String, String)>, // 新增
|
||||
) -> Self { ... }
|
||||
```
|
||||
|
||||
**③ `with_extra_headers()` builder 方法**
|
||||
|
||||
```rust
|
||||
pub fn with_extra_headers(mut self, headers: Vec<(String, String)>) -> Self {
|
||||
self.extra_headers = headers;
|
||||
self
|
||||
}
|
||||
```
|
||||
|
||||
**④ `AnthropicRequestBody` 新增字段**
|
||||
|
||||
第 450 行，`stream` 之后：
|
||||
|
||||
```rust
|
||||
struct AnthropicRequestBody {
|
||||
model: String,
|
||||
max_tokens: u32,
|
||||
// ... 已有字段 ...
|
||||
/// 请求级别自定义 HTTP 头。运行时注入，不进入 JSON 请求体。
|
||||
#[serde(skip)]
|
||||
custom_headers: HashMap<String, String>,
|
||||
}
|
||||
```
|
||||
|
||||
`#[serde(skip)]` 确保该字段不会出现在序列化后的 JSON body 中。
|
||||
|
||||
**⑤ `build_request_body()` 从 extra 提取**
|
||||
|
||||
```rust
|
||||
let custom_headers: HashMap<String, String> = request
|
||||
.get_extra_opt("custom_headers")
|
||||
.unwrap_or_default();
|
||||
```
|
||||
|
||||
**⑥ 提取 `build_request_builder()` 统一方法（前置重构）**
|
||||
|
||||
```rust
|
||||
/// 构造 HTTP POST 请求 builder（含认证头 + 自定义头）。
|
||||
/// 认证头（x-api-key / anthropic-version）已由 Client 的 default_headers 提供。
|
||||
fn build_request_builder(
|
||||
&self,
|
||||
body: &AnthropicRequestBody,
|
||||
) -> Result<reqwest::RequestBuilder, LlmError> {
|
||||
let url = format!("{}/v1/messages", self.base_url.trim_end_matches('/'));
|
||||
let mut builder = self.http_client.post(&url).json(body);
|
||||
|
||||
for (k, v) in &self.extra_headers {
|
||||
builder = builder.header(k.as_str(), v.as_str());
|
||||
}
|
||||
|
||||
for (key, value) in &body.custom_headers {
|
||||
builder = builder.header(key.as_str(), value.as_str());
|
||||
}
|
||||
|
||||
Ok(builder)
|
||||
}
|
||||
```
|
||||
|
||||
**⑦ 改造 `chat_blocking()` 和 `chat_stream_inner()`**
|
||||
|
||||
改造前（`chat_blocking`，第 263-269 行）：
|
||||
|
||||
```rust
|
||||
let response = self
|
||||
.http_client
|
||||
.post(&url)
|
||||
.json(&body)
|
||||
.send()
|
||||
.await
|
||||
.map_err(|e| self.map_reqwest_error(e))?;
|
||||
```
|
||||
|
||||
改造后：
|
||||
|
||||
```rust
|
||||
let response = self
|
||||
.build_request_builder(&body)?
|
||||
.send()
|
||||
.await
|
||||
.map_err(|e| self.map_reqwest_error(e))?;
|
||||
```
|
||||
|
||||
`chat_stream_inner`（第 298-304 行）同理。
|
||||
|
||||
### 改动四：create_provider()（provider.rs）
|
||||
|
||||
依据约束「`create_provider()` 工厂函数不暴露配置能力」，三处分支适配 `from_parts` 的新签名时全部传 `Vec::new()`：
|
||||
|
||||
```rust
|
||||
// OpenaiResponse（第 199-207 行）
|
||||
openai_response::OpenaiResponseProvider::from_parts(
|
||||
config.base_url, config.api_key, config.model,
|
||||
client, config.timeout_secs,
|
||||
Vec::new(), // extra_headers 默认空
|
||||
)
|
||||
|
||||
// Anthropic（第 215-221 行）
|
||||
anthropic::AnthropicProvider::from_parts(
|
||||
config.base_url, config.api_key, config.model,
|
||||
client, config.timeout_secs,
|
||||
Vec::new(), // extra_headers 默认空
|
||||
)
|
||||
|
||||
// OpenAI Chat（第 185-194 行）— 已有 Vec::new()，无需改动
|
||||
```
|
||||
|
||||
### 调用方式
|
||||
|
||||
**请求级临时头**（统一 API，三 provider 通用）：
|
||||
|
||||
```rust
|
||||
request.set_extra("custom_headers", serde_json::json!({
|
||||
"ark-beta-doubao-app": "true"
|
||||
}));
|
||||
```
|
||||
|
||||
**Provider 级固定头**（构造时注入）：
|
||||
|
||||
```rust
|
||||
let provider = OpenaiResponseProvider::from_parts(...)
|
||||
.with_extra_headers(vec![
|
||||
("ark-beta-doubao-app".into(), "true".into()),
|
||||
]);
|
||||
```
|
||||
|
||||
## 风险评估
|
||||
|
||||
### 风险点与缓解措施
|
||||
|
||||
| 风险 | 等级 | 缓解措施 |
|
||||
|------|------|---------|
|
||||
| 用户通过 `custom_headers` 覆盖 `Authorization` 等认证头 | 中 | 文档说明：自定义头按遍历顺序注入，同 key 后注入覆盖前注入。agcore 作为支持库不做运行时拦截 |
|
||||
| `serde_json::from_value` 类型错误静默降级为空 HashMap | 低 | 与已有 extra 字段（builtin_tools、text_format）一致的模式，保持行为统一。类型错误时请求正常发出，只是不携带自定义头 |
|
||||
| HashMap 迭代顺序不确定影响测试确定性 | 低 | HTTP 协议不要求 header 顺序，wiremock 按名匹配。无需特殊处理 |
|
||||
| AnthropicProvider 前置重构引入回归 | 低 | 提取 `build_request_builder` 是纯重构，现有测试覆盖其请求构造行为。重构后运行现有测试套件即可验证 |
|
||||
| `build_request_builder` 签名从泛型改为具体类型 | 低 | 已确认两处调用点（chat_blocking / chat_stream_inner）传入的均为具体类型，零影响 |
|
||||
| AnthropicProvider 的 `default_headers`（x-api-key / anthropic-version）与 `extra_headers` 同名头合并行为取决于 reqwest 实现 | 低 | 明确约定 Provider 级固定头不应意图覆盖认证头；`build_request_builder` 的 doc comment 中标注认证头来源 |
|
||||
|
||||
### 设计取舍记录
|
||||
|
||||
| 决策 | 选择 | 理由 |
|
||||
|------|------|------|
|
||||
| Provider 级 vs 请求级 | 双层都支持 | 满足固定头和临时头两种场景 |
|
||||
| `create_provider` 是否暴露 extra_headers | 不暴露，只传 `Vec::new()` | 保持工厂函数签名简洁，固定头通过 builder 方法注入 |
|
||||
| 敏感头保护 | 不做运行时拦截，文档说明 | agcore 是支持库，不替调用方做保护 |
|
||||
| `OpenaiChatRequest.custom_headers` 命名 | 用 `custom_headers` 而非 `extra_headers` | 避免与已有的 `extra_headers: Option<Value>`（OpenAI API wire 字段）混淆 |
|
||||
|
||||
## 验证标准
|
||||
|
||||
### 单元测试（每 provider 4 个）
|
||||
|
||||
| 测试 | 验证点 |
|
||||
|------|--------|
|
||||
| `*_custom_headers_from_extra` | `convert_request` / `build_request_body` 能从 extra 提取 `custom_headers` |
|
||||
| `*_custom_headers_skipped_in_json` | `#[serde(skip)]` 确保 custom_headers 不进入序列化 JSON body |
|
||||
| `*_custom_headers_invalid_type_fallback` | 传入错误类型（如字符串而非对象）时静默降级为空 HashMap |
|
||||
| `*_extra_headers_from_constructor` | 验证 `from_parts` / `new_with_name_and_headers` 传入的 `extra_headers` 在 `build_request_builder` 中被正确注入到 HTTP 请求头 |
|
||||
|
||||
### 集成测试（每 provider 4 个，wiremock）
|
||||
|
||||
| 测试 | 验证点 |
|
||||
|------|--------|
|
||||
| `*_custom_headers_are_sent` | mock 匹配器验证 HTTP 请求确实携带自定义头 |
|
||||
| `*_provider_level_headers_are_sent` | 验证 Provider 级固定头（通过 `with_extra_headers` 注入）确实出现在 HTTP 请求中 |
|
||||
| `*_custom_headers_override_provider_headers` | 当 Provider 级和请求级设置了相同 key 但不同值时，最终 HTTP 请求携带的是请求级的值 |
|
||||
| `*_custom_headers_can_override_auth_header` | 注入含 `Authorization` 同 key 的 `custom_headers`，验证最终认证头值被覆盖（使行为可见、可预测，与文档风险说明一致） |
|
||||
|
||||
### 回归验证
|
||||
|
||||
1. 运行 `cargo test --features full` 确保所有现有测试通过
|
||||
2. `cargo clippy --features full` 无新警告
|
||||
3. `cargo fmt --check` 格式一致

# Builtin Tools 注入修复方案
|
||||
|
||||
## 背景与目标
|
||||
|
||||
### 问题描述
|
||||
|
||||
agcore 的 OpenaiResponseProvider 在通过 extra 逃生舱注入内置工具（`web_search` / `file_search`）时存在两层缺陷，导致 builtin_tools 完全不生效：
|
||||
|
||||
1. **分支逻辑错位**（`convert_request`，第 615-640 行）：builtin_tools 注入代码被嵌套在 `tools_defs` 非空的 `else` 分支内。当调用方只提供 builtin_tools 而不提供 tools_defs 时，分支走 `if tools_defs.is_empty() { None }`，注入代码完全不执行。
|
||||
|
||||
2. **枚举不完整**（`ResponseTool`，第 136-146 行）：枚举只有 `Function` 一种变体，非 `function` 类型的 builtin 工具（如 `type: "web_search"`）反序列化失败，退化为 `name: ""` 的空函数定义，API 层面被拒绝。
|
||||
|
||||
### 目标
|
||||
|
||||
- 修复 builtin_tools 注入逻辑，使纯内置工具、混用场景均正常工作
|
||||
- 不破坏现有 tools_defs 功能
|
||||
- 添加回归测试
|
||||
|
||||
## 需求分析
|
||||
|
||||
### 功能需求
|
||||
|
||||
| # | 需求 | 优先级 |
|
||||
|---|------|--------|
|
||||
| F1 | `tools_defs` 为空、`builtin_tools` 非空时，正确注入内置工具 | P0 |
|
||||
| F2 | `tools_defs` 和 `builtin_tools` 同时非空时，合并注入 | P0 |
|
||||
| F3 | 两端均为空时，tools 字段为 None（回归保底） | P0 |
|
||||
| F4 | 无效的 builtin_tools 值不导致崩溃，跳过并告警 | P1 |
|
||||
|
||||
### 非功能需求
|
||||
|
||||
- 不做底层架构改造（extra 逃生舱机制不变）
|
||||
- 不改 `openai.rs`（Chat Completions API 不支持内置工具）
|
||||
|
||||
## 方案设计
|
||||
|
||||
### 总体架构
|
||||
|
||||
修复分三步，对应三层独立但不相互依赖的改动：
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────────┐
|
||||
│ convert_request() │
|
||||
│ │
|
||||
│ [改动二] 重构分支逻辑 │
|
||||
│ ┌─────────────────────────────────────────┐ │
|
||||
│ │ tools_defs ──→ 生成 Vec<ResponseTool> │ │
|
||||
│ │ builtin_tools ──→ 追加到同一 Vec │ │
|
||||
│ │ 两者都空 ──→ None; 否则 ──→ Some(items) │ │
|
||||
│ └─────────────────────────────────────────┘ │
|
||||
│ │
|
||||
│ [改动三] 错误处理 │
|
||||
│ unwrap_or_else ──→ match + warn! │
|
||||
└─────────────────────────────────────────────────┘
|
||||
│
|
||||
▼
|
||||
┌─────────────────────────────────────────────────┐
|
||||
│ ResponseTool 枚举 │
|
||||
│ │
|
||||
│ [改动一] 添加 Builtin(Value) 变体 │
|
||||
│ 自定义 Serialize/Deserialize 避免信息丢失 │
|
||||
└─────────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
### 改动一：扩展 `ResponseTool` 枚举
|
||||
|
||||
**位置**：第 136-146 行
|
||||
|
||||
**现状**：
|
||||
```rust
|
||||
#[derive(Debug, Clone, Serialize, Deserialize)]
|
||||
#[serde(tag = "type", rename_all = "snake_case")]
|
||||
pub(crate) enum ResponseTool {
|
||||
#[serde(rename = "function")]
|
||||
Function {
|
||||
name: String,
|
||||
description: String,
|
||||
parameters: Value,
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
**改后**（需要自定义 Serialize/Deserialize）：
|
||||
```rust
|
||||
/// NOTE: 仅在请求序列化路径使用（convert_request → build_request_builder → HTTP body）。
|
||||
/// 响应反序列化走 ResponseOutputItem，不经过此类型。
|
||||
/// 自定义 Deserialize 服务于 convert_request 内 extra 字段反序列化。
|
||||
#[derive(Debug, Clone)]
|
||||
pub(crate) enum ResponseTool {
|
||||
Function {
|
||||
name: String,
|
||||
description: String,
|
||||
parameters: Value,
|
||||
},
|
||||
/// 非 function 类型的工具（如 web_search / file_search / code_interpreter）。
|
||||
/// 直接透传原始 JSON Value，不做结构化解析，避免信息丢失。
|
||||
Builtin(Value),
|
||||
}
|
||||
|
||||
impl Serialize for ResponseTool {
|
||||
fn serialize<S: serde::Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error> {
|
||||
match self {
|
||||
ResponseTool::Function { name, description, parameters } => {
|
||||
let mut map = serde_json::Map::new();
|
||||
map.insert("type".into(), Value::String("function".into()));
|
||||
map.insert("name".into(), Value::String(name.clone()));
|
||||
map.insert("description".into(), Value::String(description.clone()));
|
||||
map.insert("parameters".into(), parameters.clone());
|
||||
map.serialize(serializer)
|
||||
}
|
||||
ResponseTool::Builtin(value) => value.serialize(serializer),
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
impl<'de> Deserialize<'de> for ResponseTool {
|
||||
fn deserialize<D: serde::Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error> {
|
||||
let value = Value::deserialize(deserializer)?;
|
||||
match value.get("type").and_then(|t| t.as_str()) {
|
||||
Some("function") => {
|
||||
let name = value.get("name").and_then(|n| n.as_str()).unwrap_or_default().to_string();
|
||||
let description = value.get("description").and_then(|d| d.as_str()).unwrap_or_default().to_string();
|
||||
let parameters = value.get("parameters").cloned().unwrap_or(Value::Null);
|
||||
Ok(ResponseTool::Function { name, description, parameters })
|
||||
}
|
||||
_ => Ok(ResponseTool::Builtin(value)),
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
关键点：
|
||||
- 自定义 `Serialize`：`Builtin` 变体直接输出原始 Value（不包裹额外标记）
|
||||
- 自定义 `Deserialize`：非 `"function"` 类型自动走 `Builtin(Value)` 分支
|
||||
- 保留原始 JSON 结构，避免信息丢失（如 `search_context_size`、`user_location` 等字段）
|
||||
|
||||
### 改动二：修复 `convert_request` 分支逻辑
|
||||
|
||||
**位置**：第 615-640 行
|
||||
|
||||
**现状**（伪代码）：
|
||||
```
|
||||
if tools_defs.is_empty() {
|
||||
None // ← builtin_tools 被完全跳过
|
||||
} else {
|
||||
从 tools_defs 生成 Vec<ResponseTool>
|
||||
if let Some(builtin_tools) {
|
||||
for v in extra {
|
||||
items.push(from_value(v)) // ← 只有进了 else 才执行
|
||||
}
|
||||
}
|
||||
Some(items)
|
||||
}
|
||||
```
|
||||
|
||||
**改后**（伪代码）：
|
||||
```
|
||||
let mut items: Vec<ResponseTool> = Vec::new();
|
||||
|
||||
// 1. 始终处理 tools_defs
|
||||
items.extend(tools_defs.into_iter().map(|t| ResponseTool::Function { ... }));
|
||||
|
||||
// 2. 始终处理 builtin_tools（与 tools_defs 解耦）
|
||||
if let Some(builtin_tools) = builtin_tools {
|
||||
for v in extra {
|
||||
// 见改动三
|
||||
items.push(serde_json::from_value(v).unwrap_or_else(|_| { ... }));
|
||||
}
|
||||
}
|
||||
|
||||
// 3. 两者都空 → None；否则 → Some
|
||||
if items.is_empty() { None } else { Some(items) }
|
||||
```
|
||||
|
||||
### 改动三：改进错误处理
|
||||
|
||||
**位置**：第 630-636 行（`unwrap_or_else` 部分）
|
||||
|
||||
**现状**：
|
||||
```rust
|
||||
items.push(serde_json::from_value(v).unwrap_or_else(|_| {
|
||||
ResponseTool::Function {
|
||||
name: String::new(),
|
||||
description: String::new(),
|
||||
parameters: Value::Null,
|
||||
}
|
||||
}));
|
||||
```
|
||||
|
||||
**改后**：
|
||||
```rust
|
||||
match serde_json::from_value(v.clone()) {
|
||||
Ok(tool) => items.push(tool),
|
||||
Err(e) => {
|
||||
let raw = serde_json::to_string(&v).unwrap_or_default();
|
||||
warn!(tool = %raw, error = %e, "skipped invalid builtin_tool");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
`warn!` 输出被反序列化的 Value 摘要，便于生产排障时定位问题（无需复现调用方输入）。
|
||||
|
||||
`unwrap_or_else` 的错误值（空函数定义）在 OpenAI API 层会被拒绝，无实际价值。替换为 `match` + `warn!` 可明确跳过并记录原因。
|
||||
|
||||
### 改动四：添加测试
|
||||
|
||||
在文件末尾 `#[cfg(test)]` 区域或 `tests/` 目录新增 6 个测试用例：
|
||||
|
||||
| # | 用例名 | 场景 | 验证点 |
|
||||
|---|--------|------|--------|
|
||||
| T1 | `test_builtin_only` | 仅提供 builtin_tools | tools 为 Some，含正确 type |
|
||||
| T2 | `test_mixed_tools` | 同时提供 tools_defs + builtin_tools | 合并后 items 顺序/数量正确 |
|
||||
| T3 | `test_no_tools` | 两端均为空 | tools 为 None |
|
||||
| T4 | `test_invalid_builtin` | builtin_tools 含无效 JSON | 不崩溃，有效项保留 |
|
||||
| T5 | `test_function_wire_format` | ResponseTool::Function 序列化 | JSON 结构与改动前一致（AC7） |
|
||||
| T6 | `test_builtin_roundtrip` | ResponseTool::Builtin 反序列化+序列化 | 原始 JSON 结构保留 |
|
||||
|
||||
## 实现计划
|
||||
|
||||
### 步骤
|
||||
|
||||
| 步骤 | 改动 | 文件 | 估算 |
|
||||
|------|------|------|------|
|
||||
| 1 | 扩展 `ResponseTool` 枚举，添加 `Builtin(Value)` + 自定义 Serialize/Deserialize | `openai_response.rs:136-146` | 40 行 |
|
||||
| 2 | 重构 `convert_request` 分支逻辑，解耦 tools_defs 与 builtin_tools | `openai_response.rs:615-640` | 15 行 |
|
||||
| 3 | 替换 `unwrap_or_else` 为 `match` + `warn!` | `openai_response.rs:630-636` | 5 行 |
|
||||
| 4 | 添加 6 个测试用例 | `openai_response.rs` 末尾 | 70 行 |
|
||||
| 5 | `cargo test` 验证全部通过 | - | - |
|
||||
|
||||
### 优先级
|
||||
|
||||
**P0（核心修复）**：步骤 1 + 2，修复分支逻辑和枚举不完整问题。
|
||||
**P1（健壮性）**：步骤 3，改进错误处理。
|
||||
**P1（质量保障）**：步骤 4 + 5，测试覆盖。
|
||||
|
||||
### 依赖关系
|
||||
|
||||
无外部依赖。全部改动限定在 `openai_response.rs` 一个文件内。
|
||||
|
||||
## 风险评估
|
||||
|
||||
| 风险 | 概率 | 影响 | 缓解措施 |
|
||||
|------|------|------|----------|
|
||||
| 自定义 Serialize/Deserialize 实现遗漏边界情况 | 低 | 中 | 测试覆盖所有分支：Function / Builtin / 无效值 |
|
||||
| 现有 `Function` 序列化格式变化 | 低 | 高 | 自定义 Serialize 保持与原 derive 行为一致，测试覆盖 wire 格式 |
|
||||
| `warn!` 日志在生产环境未配置 logger 导致 panic | 低 | 中 | 使用 `tracing::warn!`（已导入），项目已初始化 tracing logger |
|
||||
|
||||
### 回滚方案
|
||||
|
||||
单文件改动，回滚只需 `git checkout -- src/llm/provider/openai_response.rs`。
|
||||
|
||||
## 验收标准
|
||||
|
||||
| # | 验收条件 | 验证方式 |
|
||||
|---|----------|----------|
|
||||
| AC1 | `tools_defs` 空 + `builtin_tools` 含 `{"type":"web_search"}` → 请求体 `tools` 包含 `{"type":"web_search"}` | 单测 T1 |
|
||||
| AC2 | 混用场景 → tools 数组同时包含 function 和非 function 工具 | 单测 T2 |
|
||||
| AC3 | 两端空 → tools 字段为 null/None | 单测 T3 |
|
||||
| AC4 | 无效 builtin_tools → 不 panic，有效项不受影响 | 单测 T4 |
|
||||
| AC5 | 全部现有测试通过 | `cargo test` |
|
||||
| AC6 | `cargo clippy` 无新增警告 | `cargo clippy` |
|
||||
| AC7 | `ResponseTool::Function` 序列化后的 JSON 结构与改动前一致 | 单测：验证字段顺序和值 |

v0.4.0 的完整规划已移入独立的 [`roadmap-v0.4.0.md`](./roadmap-v0.4.0.md)，包含 5 个增量 Phase：
|
||||
|
||||
| 功能 | 说明 | 预计版本 |
|
||||
|------|------|---------|
|
||||
| Multi-Agent Swarm 编排 | Supervisor/Subgraph 模式，基于 v0.3 dispatch 构建 | v0.4 |

## 设计笔记
|
||||
|
||||
### Checkpointer 分层存储模型
|
||||
|
||||
> 来源：v0.4.0 规划讨论中涉及增量 Checkpoint 的技术推演。当前全量 JSON checkpoint 够用，但为未来优化预留设计方案。
|
||||
|
||||
#### 分层叠加模型（OverlayFS 模式）
|
||||
|
||||
受容器分层文件系统启发，增量 Checkpoint 可以借鉴 overlayfs 的"底层只读 + 上层可写叠加"设计：
|
||||
|
||||
**全量基座（只读）**：
|
||||
```rust
|
||||
pub struct SnapshotBase {
|
||||
pub checkpoint_id: String,
|
||||
pub session_id: String,
|
||||
pub snapshot: SessionSnapshot, // 完整 JSON 化状态
|
||||
}
|
||||
```
|
||||
|
||||
**增量层（叠加 diff）**：
|
||||
```rust
|
||||
pub struct SnapshotLayer {
|
||||
pub base_checkpoint_id: String,
|
||||
pub applies_to_id: String, // 在哪个 checkpoint 上叠加
|
||||
pub diff: Vec<DiffOp>, // JSON Patch 操作集合
|
||||
}
|
||||
|
||||
pub enum DiffOp {
|
||||
MessageAppended { message: Message },
|
||||
SlotChanged { slot_id: String, diff: serde_json::Value },
|
||||
TurnIndexIncremented { from: u32, to: u32 },
|
||||
CostUpdated { diff: CostTracker },
|
||||
}
|
||||
```
|
||||
|
||||
**重建路径**：
|
||||
```
|
||||
rollback_load("session_x", 6)
|
||||
→ 读取 "ckpt:{session_x}:base"（全量）
|
||||
→ 读取 "ckpt:{session_x}:layer:1" ~ "ckpt:{session_x}:layer:6"
|
||||
→ 依次应用 layer.1 → layer.2 → ... → layer.6
|
||||
→ 得到 session_6 的状态
|
||||
```
|
||||
|
||||
**层折叠（类似 docker squash）**：
|
||||
```
|
||||
layer.1 → layer.2 → layer.3 → layer.4 → layer.5
|
||||
↓ 合并
|
||||
base.ckpt'（包含 layer.1-3）→ layer.4 → layer.5
|
||||
```
|
||||
|
||||
#### Shadow FS 模型（运行中保护）
|
||||
|
||||
与分层模型互补，shadow 模型适用于运行中的 session 保护而非长期存储：
|
||||
|
||||
```rust
|
||||
// submit_turn 在 shadow session 上执行，commit 时才原子切换
|
||||
let shadow = current_session.fork(); // 复用 ContextSlot::fork
|
||||
let result = shadow.submit_turn(input).await;
|
||||
if result.is_ok() {
|
||||
current_session.commit(shadow); // 原子替换
|
||||
} else {
|
||||
drop(shadow); // 丢弃，当前 session 完好无损
|
||||
}
|
||||
```
|
||||
|
||||
#### 适用场景对比
|
||||
|
||||
| 模型 | 适合场景 | 不适合场景 |
|
||||
|------|---------|-----------|
|
||||
| **分层叠加（OverlayFS）** | Checkpoint 链长期存储、time-travel、多版本回退 | session 较小（< 10KB/轮）时复杂度不值得 |
|
||||
| **Shadow FS（CoW）** | 运行中 session 保护、防止 submit_turn 失败污染 | 不能替代 checkpoint 链、不支持多时间点回退 |
|
||||
|
||||
**触发条件**：当单 session checkpoint 超过 500KB 且频繁保存导致性能瓶颈时，考虑实现分层模型。

> - `LlmProvider` trait + `ProviderCapabilities` + `ProviderFeatures` 从 `provider.rs` 移至新建的 `provider_trait.rs`，归属 `#[cfg(feature = "llm")]`（ADR-1，纯 Mock 场景不再需要 provider feature）
|
||||
> - `llm` feature 补充 imply `futures-util`（修复 `cycle.rs` 隐式依赖）
|
||||
> - `bundle()` 方法加 `#[cfg(feature = "engine")]` 门控修复 dead_code 警告
|
||||
> - `prompt_composer` / `custom_tool` 的 required-features 需额外 `llm`（`response_v2.rs` 依赖 `LlmError`，预存耦合）
|
||||
> - cargo fmt 全量格式化（修复预存格式问题，CI format job 可通过）
|
||||
>
|
||||
> 实施方案见 [`docs/26-step1-phase20-cargo-features-implementation.md`](./26-step1-phase20-cargo-features-implementation.md) 和 [`docs/27-step3-phase26-ci-verification.md`](./27-step3-phase26-ci-verification.md)。
|
||||
|
||||
## v0.3.2 愿景
|
||||
|
||||
通过 Cargo features 拆分，让下游按需选择模块，跳过不需要的编译单元和重型依赖。
|
||||
|
||||
## v0.3.2 总体范围
|
||||
|
||||
**版本等级**：patch（v0.3.2），`default = ["full"]` 保持向后兼容，非破坏性变更。
|
||||
|
||||
**改造基线**：v0.3.0 已交付 23,718 行 Rust 代码，66 个源文件。当前所有依赖全量编译——引用 agcore 就意味着拉入 rusqlite bundled、reqwest、tokio full 等全部重型依赖。
|
||||
|
||||
**改造目标**：16 个 features（10 模块级 + 5 provider + 1 工具）+ 4 个快捷组合。下游可只选 `chat` 组合跳过 SQLite 和 MCP 的编译，或只选 `document` 实现纯文档分割零外部依赖。
|
||||
|
||||
**工作性质**：纯 cfg 门控 + Cargo.toml 配置变更，不新增功能代码。
|
||||
|
||||
**总体规模**：8 个增量 Phase（Phase 20–27），预计新增/修改约 330 行配置与条件编译代码。

## 实施计划 — 8 个增量 Phase
|
||||
|
||||
> **编号说明**：Phase 20-27 接续 v0.3.0 的 Phase 13-19。
|
||||
|
||||
### 实施节奏：4 个 Step
|
||||
|
||||
将 8 个 Phase 合并为 4 个实施步骤，平衡变更风险与执行效率。
|
||||
|
||||
| Step | Phase | 内容 | 验证方式 | 预估行数 |
|
||||
|------|-------|------|---------|---------|
|
||||
| **Step 1** ✅ | Phase 20-25 | Cargo.toml features 定义 + 依赖 optional 化 + 全模块 cfg 门控（合并实施） | 14 条编译验证全通过 + `cargo test -F full` 427 passed | ~100 |
|
||||
| **Step 2** | （已合并至 Step 1） | — | — | — |
|
||||
| **Step 3** ✅ | Phase 26 | 测试矩阵验证 + 修复 cfg 遗漏 + LlmProvider trait 归属修正 + examples required-features | 6 种组合全部测试通过 + clippy 0 警告 + 18 个 example 单独编译通过 | ~80 |
|
||||
| **Step 4** ✅ | Phase 27 | README + 示例标注 + 总入口同步 | review 通过 | ~100 |
|
||||
|
||||
**Step 1 单独成步**：Cargo.toml 是基础设施变更，编译通过后打 checkpoint，后续都是纯源文件变更。
|
||||
|
||||
**Step 2 合并 Phase 21–25**：全是 `#[cfg(feature = "...")]` 公式化插门控，按依赖顺序（底层模块 → LLM/Provider → Tools/MCP → Memory → Agent/Engine）实施，每插一个 feature 门控就验证。按子模块分批 commit 控制粒度。

|
||||
| **20.5** | feature imply 链配置：`prompt → llm-types`，`llm → llm-types`，`tools → llm-types`，`memory → document`，`agent → llm + tools + memory`（不含 tools-mcp），`engine → agent` | `Cargo.toml` | `cargo build --features "agent,provider-openai"` transitive 依赖自动拉取 |

|
||||
- 独立 `examples` job 验证所有 example 在完整 features 下编译
|

- 每个 job 设置 `timeout-minutes` 兜底

# AG Core Roadmap — v0.4.0
|
||||
|
||||
> 本文件聚焦 **v0.4.0 版本** 的规划。Phase A-E 计划中，覆盖多 Agent 编排、Human-in-the-loop 与 Steering、语义压缩、自动校正。
|
||||
> 返回总入口：[`roadmap.md`](./roadmap.md)
|
||||
|
||||
## v0.4.0 愿景
|
||||
|
||||
从 v0.3 的"多 Agent 基础系统"升级为"多 Agent 多职责编排系统"。补齐高层编排抽象（Swarm/Supervisor/Subgraph）、生产级人工干预能力（HITL + Steering）、工具与消息的语义压缩（TokenJuice），以及自动质量校正（Reflection）。为即将开发的多 Agent 协作产品提供完整的编排、干预与质量保证层。
|
||||
|
||||
## v0.4.0 总体范围
|
||||
|
||||
**总体规模**：5 个增量 Phase（Phase A-E），总新增代码约 1,950 行，零强制新外部依赖，零破坏性变更。
|
||||
|
||||
### 架构决策
|
||||
|
||||
**路线选择**：采用轻量编排模式（路线 A），不引入通用有向图引擎。通过 `Swarm::star()` / `Swarm::sequential()` / `Swarm::hierarchical()` 等具名模式提供编排能力，底层复用现有 `dispatch` / `create_child` / `SessionManager` 基础设施。预留路线 B（StateGraph 抽象）作为未来版本的升级路径。
|
||||
|
||||
**模块位置**：
|
||||
- 编排逻辑 → `src/engine/supervisor.rs`（新增）
|
||||
- 内建工具 → `src/tools/builtin.rs`（新增）
|
||||
- TokenJuice 压缩 → `src/llm/compress.rs`（新增）
|
||||
- Steering 机制 → `src/engine/steer.rs`（新增，或并入 supervisor.rs）
|
||||
|
||||

### 实施计划 — 5 个增量 Phase
|
||||
|
||||
> **编号说明**：Phase A-E 为 v0.4.0 专属编号，接续已完成的 Phase 30。
|
||||
|
||||
---
|
||||
|
||||
#### Phase A: Swarm 编排抽象（Star / Sequential / Hierarchical + Subgraph）
|
||||
|
||||
**目标**：在现有 `dispatch` 原语基础上，提供声明式多 Agent 编排 API。Supervisor 作为 `Arc<dyn Agent>`，通过内建工具 `dispatch_sub_agent` 驱动子 Agent 执行。
|
||||
|
||||
**交付物**：
|
||||
1. `src/engine/supervisor.rs` 新文件：
|
||||
- `Swarm` 枚举/结构体：`Swarm::star()`（星型，一个 Supervisor + N 个 Worker）、`Swarm::sequential()`（顺序链 A→B→C）、`Swarm::hierarchical()`（层次嵌套，Supervisor 下的 Sub-Supervisor）
|
||||
- 各模式的 `build()` 和 `run(input)` 方法
|
||||
- 底层通过 `SessionManager::dispatch()` / `dispatch_all()` 实现
|
||||
2. `src/tools/builtin.rs` 新文件：
|
||||
- `dispatch_sub_agent(name, task, config)` 内建工具 — 从 Agent 注册表查找 Agent 工厂 → `SessionManager::dispatch()`
|
||||
3. `AgentRegistry`：`HashMap<String, Box<dyn Fn() -> Arc<dyn Agent>>>` 轻量工厂注册表（约 50 行）
|
||||
4. Subgraph 嵌套：`Swarm::hierarchical()` 支持 `group(name, inner_swarm)`，内层 Swarm 作为子节点编译后嵌入
|
||||
|
||||
**设计要点**：
|
||||
- Supervisor 就是 `Arc<dyn Agent>`，不新增 `SupervisorAgent` trait
|
||||
- 路由逻辑写在 Supervisor 的 system prompt 中（LLM 决定的动态路由）
|
||||
- 三种模式覆盖常见编排拓扑，不引入通用图引擎（路线 B 留作未来）
|
||||
- Subgraph 编译为独立的 `SessionManager` 子树（复用 `create_child` 的父子关系）
|
||||
|
||||
**依赖**：Phase 18（SubAgent dispatch / SessionManager）
|
||||
**优先级**：P0
|
||||
**预估规模**：约 500 行
|
||||
**状态**：📋 待实施
|
||||
|
||||
---
|
||||
|
||||
#### Phase B: 结果聚合 + 编排模式完善
|
||||
|
||||
**目标**：让 Supervisor 能智能地合并 Worker 结果。完善三种编排模式的容错性和易用性。
|
||||
|
||||
**交付物**：
|
||||
1. `aggregation_prompt` 模板系统 — 内建 `DEFAULT_AGGREGATION_PROMPT`，用户可自定义聚合逻辑
|
||||
2. `DispatchConfig` 扩展：
|
||||
- `result_key: Option<String>` — 将子结果存入 `session_memory` 的指定 key，供后续阶段使用
|
||||
- `aggregate_strategy: AggregateStrategy` — `Concatenate` / `Summarize` / `Custom(Value)`
|
||||
3. 编排模式增强：
|
||||
- `Swarm::sequential()` 支持失败时停止 / 跳过 / 重试策略
|
||||
- `Swarm::star()` 支持 Worker 超时
|
||||
4. 端到端示例 3 个：
|
||||
- `swarm_star_demo.rs` — 星型编排 + 并发派发 + 结果聚合
|
||||
- `swarm_sequential_demo.rs` — 串联流水线
|
||||
- `swarm_hierarchical_demo.rs` — 层次嵌套（Supervisor → Sub-Supervisor → Worker）
|
||||
|
||||
**依赖**：Phase A
|
||||
**优先级**：P0
|
||||
**预估规模**：约 200 行
|
||||
**状态**：📋 待实施
|
||||
|
||||
---
|
||||
|
||||
#### Phase C: Human-in-the-loop + 用户 Steering
|
||||
|
||||
**目标**：生产级多 Agent 系统的关键门禁。提供执行中暂停-审批-恢复机制，以及用户运行中校正方向的能力。
|
||||
|
||||
**交付物**：
|
||||
1. `src/engine/steer.rs` 新文件：
|
||||
- `interrupt(value)` 函数 — 在工具循环中插入暂停点，持久化当前状态后返回控制权
|
||||
- `Command` 枚举：
|
||||
- `Command::Resume(bool)` — 二元审批（批准/拒绝）
|
||||
- `Command::ResumeWith(Correction)` — 结构化校正（修改工具参数 / 调整方向）
|
||||
2. `LlmCycle` 扩展：可中断工具循环模式
|
||||
- `submit_with_tools_interruptible()` — 支持在工具批处理边界检查中断信号
|
||||
- 中断时保存当前 `LlmCycle` 状态到 checkpoint
|
||||
3. `HookEvent::OnInterrupt` / `OnSteer` 新变体 — 监听中断和校正事件
|
||||
4. `SessionManager::resume_turn(session_id, resume_data)` — 从 checkpoint 恢复并注入审批结果
|
||||
5. `tools/builtin.rs` 扩展：
|
||||
- `request_approval(question, context)` — 请求用户审批
|
||||
- `emit_steer(correction)` — 用户校正
|
||||
6. Steering 生命周期：
|
||||
- `interrupt` → 用户收到提示 → 用户决定方向 → `Command::ResumeWith(correction)` → Agent 在新方向上继续
|
||||
|
||||
**设计要点**：
|
||||
- User Steering 不是简单的"批准/拒绝"，而是 `Correction { action, reason, amended_params }` 结构化指令
|
||||
- Steering 消息在工具批处理边界（Worker 返回后、Supervisor 决策前）注入，不中断正在执行的工具
|
||||
- 继承 `ContextSlot::fork/merge` 模式，steer 前 fork 快照，允许用户回退到 steer 前状态
|
||||
|
||||
**依赖**：Phase A（Swarm 编排）
|
||||
**优先级**：P0
|
||||
**预估规模**：约 500 行
|
||||
**状态**：📋 待实施
|
||||
|
||||
---
|
||||
|
||||
#### Phase D: TokenJuice 语义压缩
|
||||
|
||||
**目标**：替代当前字节级截断（`microcompact` 的 `[pruned]`），提供语义级别的压缩。在三层管道中接入：工具结果压缩、对话历史压缩、跨 Agent 消息压缩。
|
||||
|
||||
**交付物**：
|
||||
1. `src/llm/compress.rs` 新文件：
|
||||
- `Compressor` trait（`async fn compress(&self, input: &str, ctx: &CompressionContext) -> Result<String>`）
|
||||
- `CompressionContext`：`target_tokens` / `preserve_keys` / `strategy`
|
||||
- `CompressionStrategy` 枚举：`Semantic { model }`（LLM 摘要）、`Extractive { ratio }`（抽取式）、`Hybrid { semantic_first }`（混合）
|
||||
- `SemanticCompressor` 实现（复用已有 provider 做 LLM 摘要压缩）
|
||||
- `ExtractiveCompressor` 实现（确定性关键句提取，零 LLM 调用）
|
||||
2. 三层接入点：
|
||||
- **工具结果压缩**：在 `run_tool_loop` 中，`tool.execute()` 后插入 `compress_result()`，压缩结果再 `push ToolResult`
|
||||
- **对话历史压缩**：在 `load_messages()` 后插入 `compress_history()`，替代/补充 `microcompact`
|
||||
- **跨 Agent 消息压缩**：在 `inherit_session_memory` 的子 memory 写入前压缩（减少子 Agent 的 context 水位）
|
||||
3. `CycleConfig` / `CompactConfig` 扩展：
|
||||
- `token_compression: Option<CompressionConfig>` — 可选语义压缩配置
|
||||
- `fallback_to_microcompact: bool`（默认 `true`）— LLM 压缩失败时退化为字节截断
|
||||
4. TokenJuice 与现有 `microcompact` 的关系：
|
||||
- `microcompact` 保留为最轻量级兜底（零 LLM 调用）
|
||||
- TokenJuice 是可选增强层（默认关闭，用户 opt-in）
|
||||
|
||||
**设计要点**：
|
||||
- 零新外部依赖：LLM 摘要压缩复用已有 provider，抽取式压缩纯 Rust 实现
|
||||
- 与现有 `CompactState` 断路器模式兼容（LLM 压缩失败 3 次后自动降级到 `microcompact`）
|
||||
- `preserve_keys` 确保关键数据（数字、ID、SQL、代码片段）不被压缩掉
|
||||
|
||||
**依赖**：Phase 14（Embedding trait 可选参考）
|
||||
**优先级**：P0
|
||||
**预估规模**：约 400 行
|
||||
**状态**：📋 待实施
|
||||
|
||||
---
|
||||
|
||||
#### Phase E: 自动校正 / Reflection
|
||||
|
||||
**目标**：实现 Agent 输出后的自我质量评估与自动修正循环。基于 `interrupt/resume` 基础设施，构建 Producer-Critic 闭环。
|
||||
|
||||
**交付物**：
|
||||
1. `src/engine/reflect.rs` 新文件：
|
||||
- `ReflectionConfig`：`max_cycles`（默认 2）/ `critic_agent`（可选不同模型）/ `criteria: Vec<String>`（评估标准）
|
||||
- `Reflectable` trait：`fn reflection_criteria(&self) -> Vec<String>` + `fn needs_refinement(&self, critique: &Critique) -> bool`
|
||||
- `ReflectionLoop`：`evaluate(output) → Critique` → `should_refine? → yes: refine(output, critique) → 循环 / no: 返回`
|
||||
2. Swarm 内建 Reflection 模式：
|
||||
- `Swarm::reflect(producer_agent, critic_agent)` — 专用 Reflection Swarm
|
||||
- 可在 Supervisor 流程中嵌入 `reflect_on(worker_result)` — 对 Worker 结果自动过一遍质量检查
|
||||
3. `Critique` 结构体：`issues: Vec<Issue>` / `score: f32` / `should_refine: bool` / `suggestions: Vec<String>`
|
||||
4. `tools/builtin.rs` 扩展：`verify_output(claim, evidence)` 工具 — 让 Agent 自行验证输出真实性
|
||||
|
||||
**设计要点**：
|
||||
- Producer 和 Critic 使用**不同模型**（避免同一模型的自我审查盲区 bias）
|
||||
- 上限 2-3 轮（第一轮修正捕获 70–80% 改善空间，第 4+ 轮收益递减）
|
||||
- 基于已有 `HookEvent::OnTurnEnd` 或扩展 `HookEvent::OnOutputGenerated` 触发反思
|
||||
- 失败静默：Reflection 失败不阻断主流程（`tracing::warn!` 后继续交付原始输出）
|
||||
|
||||
**依赖**：Phase C（interrupt/resume 基础设施）
|
||||
**优先级**：P0
|
||||
**预估规模**：约 350 行
|
||||
**状态**：📋 待实施
