---- - -## AG-UI 转发与落库（支持短路） - -### 转发规则 - -- `DIRECT_EXECUTION`：转发 `IntentResult.assistant_text`（不经过 organization）。 -- `NEEDS_EXECUTION`：仅转发 `OrganizationResult.assistant_text`。 -- 额外必须转发工具事件： - - `tool_call`（工具调用请求，供前端展示/审批） - - `tool_result`（工具执行结果，供前端展示） -- 现状备注：当前 runtime 仅发送 `llmStarted/llmChunk/llmFinished`，尚未发出 `tool_call/tool_result`；需按本计划补齐。 - -### 落库规则 - -- 文本审计消息（intent/execution 原始结构）可写入 `seq < 0`（仅后端审计）。 -- 用户可见消息必须写入 `seq > 0`，包括： - - assistant 最终回复 - - `tool_call` - - `tool_result` -- 为保证前端可正常拉取与审批，工具调用相关消息禁止使用负 `seq`。 -- 短路场景最少包含两条正序可见消息： - - 用户消息（正 seq） - - assistant 回复（正 seq） - -### 消息模型约束现状（基于现有代码） - -- `messages.role` 当前由应用模型枚举约束：`user` / `assistant` / `system` / `tool`。 -- `metadata` 当前有 `MessageMetadata*` Pydantic 类型定义（`user_input` / `tool_call` / `tool_result` / `assistant_output`）。 -- 现有 `append_message()` 接口接收通用 `dict`，数据库层不做 metadata schema 强校验。 -- 执行约束：后续实现保持现有 metadata 类型体系，必要时在 repository 入口增加二次校验。 - ---- - -## 计费设计（Session 冻结币种） - -### 规则 - -- 在 session 创建时计算并冻结： - - `billing_currency`（当前固定 `CNY`） - - `billing_country_snapshot` -- 后续所有 message 成本按 session 冻结配置计算。 -- 用户中途修改 profile 国家，不影响已创建 session。 -- 不做 USD/CNY 汇率换算，不引入汇率快照字段参与计费。 - -### 成本审计口径（消息级，不做会话内累加） - -- 所有消息均入库（包括审计消息与展示消息）。 -- 每条 assistant 消息单独记录：`input_tokens`、`output_tokens`、`cost`、`currency`。 -- Flow 运行态不维护 `tokens/cost` 累加字段，避免重复状态来源。 -- 会话总成本/总 token 通过数据库聚合得到（实时查询或离线汇总皆可）。 - -### CrewAI 与 LiteLLM 协作边界 - -- CrewAI 官方库负责流程编排（Flow / Agent / Task / Crew）。 -- LiteLLM 负责模型调用与 usage 提取，并可执行基于自定义单价的一键 `completion_cost` 计算。 -- 两者并不冲突：即便迁移到 CrewAI 官方流程，仍可保留 LiteLLM 成本审计链路。 -- 落库标准保持不变：以消息为粒度记录成本，不依赖 Flow 内累加。 - -### 成本计算优先级（最终口径） - -1. 默认：精算优先（使用 LiteLLM `usage` + 本地人民币价格表，含 cache hit/miss 规则）。 -2. 兜底：一键 `completion_cost`（当精算所需 usage 字段缺失或模型未配置时）。 -3. 所有落库金额按 `CNY` 解释与存储，不做汇率换算。 - -### LiteLLM 自定义人民币定价方案（保留一键计算） - -DeepSeek 官方定价来源（中文）： -https://api-docs.deepseek.com/zh-cn/quick_start/pricing - -按 2026-03-06 抓取到的 `deepseek-chat (DeepSeek-V3.2)` 价格（单位：人民币 / 百万 tokens）： -- 输入（缓存命中）：`0.2 元` -- 输入（缓存未命中）：`2 元` -- 输出：`3 元` - -```python -import litellm -from litellm import completion_cost - -litellm.register_model({ - # DeepSeek-V3.2（deepseek-chat）官方人民币单价 - # 注意：completion_cost 仅支持单一 input/output 单价时， - # 如需区分 cache hit/miss，建议在 usage 维度自定义计算函数。 - "deepseek/deepseek-chat": { - "input_cost_per_token": 2.0 / 1_000_000, # CNY（按 cache miss 兜底） - "output_cost_per_token": 3.0 / 1_000_000, # CNY - }, - # qwen3.5 定价沿用项目已有本地配置，此处不覆写 -}) - -response = run_completion(...) -tokens = response["usage"] -cost_cny = completion_cost(completion_response=response) # 数值按本地单价解释为 CNY -``` - -如需严格按 DeepSeek 缓存命中/未命中分别计费，请用 `usage` 中的缓存字段做本地计算： - -```python -def calc_deepseek_cost_cny(usage: dict) -> float: - hit = int(usage.get("prompt_cache_hit_tokens", 0)) - miss = int(usage.get("prompt_cache_miss_tokens", usage.get("prompt_tokens", 0))) - out = int(usage.get("completion_tokens", 0)) - return ( - hit * (0.2 / 1_000_000) - + miss * (2.0 / 1_000_000) - + out * (3.0 / 1_000_000) - ) -``` - -落库规则： -- `input_tokens` / `output_tokens`: 使用 LiteLLM `usage`。 -- `cost`: 使用 `completion_cost` 返回值。 -- `currency`: 固定写 `CNY`。 -- `metadata.cost_source`: `custom_pricing`（若走本地单价）或 `litellm_catalog`（若走官方定价）。 - -### 模型标识修正（开发环境） - -- 项目历史配置中的 `deepseek-3.2` 统一替换为 `deepseek-chat`（官方推荐标识）。 -- 不做兼容迁移、不保留别名映射；直接修改配置与初始化数据。 -- 适用范围：当前开发环境，后续生产环境按初始化脚本落库新配置。 - -### 参考结构 - -```python -@dataclass(frozen=True) -class BillingProfile: - currency: str # 当前固定 CNY - country_snapshot: str -``` - ---- - -## Session 状态一致性 - -状态机保持不变：`pending -> running -> completed|failed`。 - -补充要求： -- `sessions.status` 与 `state_snapshot.status` 必须同事务更新。 -- 失败时写入 `error_id`。 -- 首次运行若 `title` 为空，使用首条用户输入生成标题（仅一次，不覆盖）。 - -### Session Title 生成规则 - -- 触发时机：写入首条用户消息时，且 `sessions.title IS NULL`。 -- 生成来源：该条用户输入文本。 -- 处理规则：去首尾空白、压缩换行为空格、截断到固定长度（建议 64）。 -- 回退规则：处理后为空字符串时，使用默认值 `"新会话"`。 -- 覆盖策略：只在 `title` 为空时设置，后续消息不得覆盖已有标题。 - -```python -def build_session_title(first_user_input: str, max_len: int = 64) -> str: - normalized = " ".join(first_user_input.strip().splitlines()).strip() - return (normalized[:max_len] or "新会话") -``` - ---- - -## Prompt 安全优化 - -### 风险 - -`username` / `bio` 属于用户可控输入，直接拼接 system prompt 会造成注入面扩大。 - -### 改进方案 - -1. 用户画像作为“数据块”注入，不作为“指令段”。 -2. 统一转义和长度限制（如每字段 512 字符）。 -3. 增加不可覆盖规则：用户资料内容不得覆盖系统策略。 - -### 注入策略（当前版本） - -- 仅预注入一个 `system_prompt`，来源是 `get_user_agent_context` 生成的用户画像块。 -- 该 `system_prompt` 需要注入到每一个 agent。 -- `state_prompt` 当前不纳入实现范围。 -- 阶段差异化提示暂由既有 YAML 配置承担，不在运行时动态拼接 state prompt。 -- 长度策略：当前以模板人工维护为主，不新增动态截断逻辑；优先保证注入链路正确接入。 - -### CrewAI YAML 接入现状与改造要求 - -- 仓库已存在 CrewAI 模板文件：`core/config/static/crewai/agents.yaml` 与 `tasks.yaml`。 -- 现状未发现运行时加载链路；当前运行逻辑仍以代码内构造为主。 -- 改造要求： - - 新增 CrewAI YAML loader（复用项目现有 `yaml.safe_load + pydantic` 风格）。 - - Flow 各阶段统一从 YAML 读取 agent/task 模板。 - - 通过 `prompt` 模块函数注入 `system_prompt` 与阶段变量，避免在 Flow 内散落字符串拼接。 - -### 参考实现 - -```python -import json - -def _sanitize(value: str | None, max_len: int = 512) -> str: - text = (value or "").strip() - return text[:max_len] - - -def build_global_system_prompt(ctx: UserAgentContext) -> str: - profile_payload = { - "username": _sanitize(ctx.username), - "bio": _sanitize(ctx.bio), -

-**Date:** 2026-03-06 -**Status:** Draft - ---- - -## 0. Intake Contract - -- Objective: 将 Supabase 客户端纳入统一服务生命周期管理，避免每次请求重复创建客户端。 -- Deliverable: 新增 `SupabaseService`，并基于 `service_interface.py` 的 `ServiceRegistry` 提供统一初始化/关闭路径，完成 auth 侧迁移。 -- Constraints: - - 保持现有 `core.config.settings` 的配置读取行为不变。 - - 不引入 `os.environ` 直接读取。 - - 不改变现有 API 语义。 -- Verification target: - - 通过单元测试证明 Supabase 服务初始化、关闭、健康检查行为。 - - 通过应用启动测试证明统一初始化流程可用。 - - 通过 auth 相关测试证明迁移后业务行为一致。 - ---- - -## 1. 复杂度与风险分级 - -- Complexity: `S2` - - 原因：涉及多文件改造（`services/base`、`app.py`、`v1/auth`、测试）。 -- Risk Tier: `L1` - - 原因：涉及应用启动链路和认证网关依赖，但不改变对外接口契约。 - -L1 Gate 要求：执行 `refactor-cleaner` 审视冗余与结构风险（`code-reviewer` 可选）。 - ---- - -## 2. 现状与问题 - -### 2.1 当前现状 - -- `SupabaseAuthGateway` 在 `__init__` 内直接 `create_client(...)`，每次实例化都会创建 anon/admin 客户端。 -- `get_auth_service()` 当前每次请求都会 new `SupabaseAuthGateway()`，导致客户端重复构造。 -- `ServiceRegistry` 已存在，但目前主要用于注册，应用启动仍是手写逐个初始化。 - -### 2.2 核心问题 - -1. 生命周期不统一：Supabase 没有接入应用启动/关闭的统一管理。 -2. 初始化代码重复趋势：服务增多后，`app.py` 的 lifespan 会继续膨胀。 -3. 网关构造时机风险：若在应用未初始化阶段取客户端，可能抛运行时异常。 - ---- - -## 3. 优化设计（推荐方案） - -### 3.1 方案摘要 - -在 `service_interface.py` 基础上新增统一生命周期函数，按服务名列表批量初始化/关闭；`app.py` 仅声明服务顺序，减少样板代码。Supabase 使用 `config.supabase` 作为默认配置来源，保持 settings 行为一致。 - -### 3.2 目标文件结构 - -```text -backend/src/services/base/ -├── __init__.py -├── service_interface.py # 扩展：统一生命周期函数 -├── redis.py -└── supabase.py # 新增 -``` - -### 3.3 service_interface 统一初始化能力（新增） - -在 `service_interface.py` 新增以下函数（建议命名）： - -- `resolve_registered_services(service_names: list[str]) -> list[BaseServiceProvider]` -- `initialize_registered_services(service_names: list[str]) -> tuple[bool, list[BaseServiceProvider]]` -- `close_registered_services(services: list[BaseServiceProvider]) -> bool` - -约束与行为： - -1. 初始化按 `service_names` 顺序执行。 -2. 任一服务初始化失败时： - - 返回 `False`。 - - 对已成功初始化的服务按逆序执行关闭回滚。 -3. 关闭按逆序执行，最大化依赖安全性。 -4. 日志必须包含失败服务名和错误摘要。 - -这样 `app.py` 只需声明： - -```python -SERVICE_STARTUP_ORDER = ["redis", "supabase"] -``` - -并调用统一函数，减少重复初始化样板。 - -### 3.4 SupabaseService 设计 - -`supabase.py` 关键点： - -- 继承 `BaseServiceProvider`。 -- 构造函数签名： - - `def __init__(self, settings: SupabaseSettings | None = None) -> None` - - 默认 `settings or config.supabase`，确保与当前配置源一致。 -- `initialize()`：创建 anon/admin 两个 client，失败返回 `False`。 -- `close()`： - - 清空 `_client`、`_admin_client`。 - - `self._set_initialized(False)`。 -- `health_check()`： - - 必须进行至少一个轻量真实请求验证，不仅检查本地对象存在。 - - 返回结构与 `RedisService.health_check()`风格一致（`status + details`）。 - -注册方式： - -```python -supabase_service: SupabaseService = register_service_instance( - "supabase", SupabaseService() -) -``` - -### 3.5 app.py 改造 - -当前手写 `redis_service.initialize()` 改为调用统一初始化函数。 - -目标行为： - -1. 启动阶段： - - 调用 `initialize_registered_services(["redis", "supabase"])`。 - - 失败则 `raise RuntimeError("Service initialization failed")`。 -2. 关闭阶段： - - 调用 `close_registered_services(initialized_services)`。 - -### 3.6 AuthGateway 迁移策略（避免构造时机问题） - -不建议在 `SupabaseAuthGateway.__init__` 里立即绑定 client；改为按需获取： - -- 保留网关对象轻量化。 -- 在每个业务方法内部通过 `supabase_service.get_client()` / `get_admin_client()` 取实例。 - -优点： - -1. 避免模块导入或依赖构建阶段误触未初始化 client。 -2. 对 `users/dependencies.py` 中全局缓存 gateway 的场景更安全。 -3. 不改变业务层接口。 - ---- - -## 4. 配置与兼容性保证 - -### 4.1 settings/config 行为不变 - -迁移后依然通过 `core.config.settings.config.supabase` 读取： -
