agent-platform

基于 Python 的多服务智能体开发平台脚手架。

当前仓库已经初始化为 Monorepo，包含：

• services/：核心微服务
• libs/：共享领域模型、DSL、事件、数据库和公共组件
• deployments/：本地和集群部署占位
• docs/：规划和数据库设计文档

当前已创建的服务

• api-gateway
• session-service
• workflow-service
• runtime-service
• tool-service

每个服务都提供了最小 FastAPI 启动入口和健康检查接口，数据库相关服务也已经带上了 SQLAlchemy 模型骨架与 Alembic 目录。

当前已创建的共享库

• core-domain
• core-dsl
• core-events
• core-shared
• core-db

推荐本地开发方式

建议使用 uv 或 pip 创建虚拟环境后安装各服务依赖。

cd D:\workspace\auto-platform
python -m venv .venv
.venv\Scripts\activate
pip install -e .\libs\core-shared
pip install -e .\libs\core-domain
pip install -e .\libs\core-dsl
pip install -e .\libs\core-events
pip install -e .\libs\core-db
pip install -e .\services\api-gateway
pip install -e .\services\session-service
pip install -e .\services\workflow-service
pip install -e .\services\runtime-service
pip install -e .\services\tool-service

运行示例：

cd D:\workspace\auto-platform\services\api-gateway
uvicorn app.main:app --reload --port 8000

数据库连接默认使用各服务目录下的 SQLite 文件，也可以通过环境变量覆盖：

$env:AGENT_PLATFORM_DATABASE_URL="postgresql+psycopg://user:password@localhost:5432/workflow_db"

数据层脚手架

本轮已经加入：

• libs/core-db：统一 SQLAlchemy Base、通用 mixin、命名约定
• workflow-service：应用与流程定义模型
• session-service：会话与消息模型
• runtime-service：运行与节点执行模型
• tool-service：工具定义与绑定模型
• 每个服务独立的 alembic.ini、env.py、versions/
• workflow-service：已接入 repository / application service / CRUD API
• session-service：已接入 repository / application service / CRUD API

迁移执行示例：

cd D:\workspace\auto-platform\services\workflow-service
alembic upgrade head

其他服务同理：

• services/session-service
• services/runtime-service
• services/tool-service

接口示例：

Invoke-RestMethod -Method Post `
  -Uri http://127.0.0.1:8002/workflows/apps `
  -ContentType "application/json" `
  -Body '{"tenant_id":"t1","code":"sales_assistant","name":"Sales Assistant"}'

Invoke-RestMethod -Method Post `
  -Uri http://127.0.0.1:8001/sessions `
  -ContentType "application/json" `
  -Body '{"tenant_id":"t1","app_id":"app-1","user_id":"user-1","channel_type":"web"}'

Invoke-RestMethod -Method Post `
  -Uri http://127.0.0.1:8002/workflows/versions `
  -ContentType "application/json" `
  -Body '{"tenant_id":"t1","workflow_id":"wf-1","dsl_json":{"nodes":[],"edges":[]}}'

Invoke-RestMethod -Method Post `
  -Uri http://127.0.0.1:8001/sessions/run-requests `
  -ContentType "application/json" `
  -Body '{"tenant_id":"t1","session_id":"sess-1","app_version_id":"appv-1","workflow_version_id":"wfv-1"}'

Invoke-RestMethod -Method Post `
  -Uri http://127.0.0.1:8003/runtime/runs `
  -ContentType "application/json" `
  -Body '{"tenant_id":"t1","app_id":"app-1","app_version_id":"appv-1","workflow_id":"wf-1","workflow_version_id":"wfv-1","session_id":"sess-1","initial_node":{"node_id":"start","node_type":"llm"}}'

如果不传 initial_node，runtime-service 会调用 workflow-service 读取对应的 workflow version，并从 DSL 中自动推导首节点：

Invoke-RestMethod -Method Post `
  -Uri http://127.0.0.1:8003/runtime/runs `
  -ContentType "application/json" `
  -Body '{"tenant_id":"t1","app_id":"app-1","app_version_id":"appv-1","workflow_id":"wf-1","workflow_version_id":"wfv-1","session_id":"sess-1"}'

一条链直接派发到 runtime：

Invoke-RestMethod -Method Post `
  -Uri http://127.0.0.1:8001/sessions/run-requests/dispatch `
  -ContentType "application/json" `
  -Body '{"tenant_id":"t1","session_id":"sess-1","app_id":"app-1","app_version_id":"appv-1","workflow_id":"wf-1","workflow_version_id":"wfv-1","initial_node":{"node_id":"start","node_type":"llm"}}'

工具定义示例：

Invoke-RestMethod -Method Post `
  -Uri http://127.0.0.1:8004/tools `
  -ContentType "application/json" `
  -Body '{"tenant_id":"t1","code":"search_products","name":"Search Products","tool_type":"http"}'

Invoke-RestMethod -Method Post `
  -Uri http://127.0.0.1:8004/tools/versions `
  -ContentType "application/json" `
  -Body '{"tenant_id":"t1","tool_id":"tool-1","input_schema_json":{"query":{"type":"string"}},"invoke_config_json":{"method":"GET","path":"/products/search"}}'

运行状态推进示例：

Invoke-RestMethod -Method Post `
  -Uri http://127.0.0.1:8003/runtime/node-runs/node-run-id/status `
  -ContentType "application/json" `
  -Body '{"status":"running","worker_key":"runtime-worker-1"}'

Invoke-RestMethod -Method Post `
  -Uri http://127.0.0.1:8003/runtime/runs/run-id/status `
  -ContentType "application/json" `
  -Body '{"status":"completed"}'

说明：

• 当你调用 node-runs/{node_run_id}/status 更新节点状态时，runtime-service 会自动聚合当前运行下所有 node_run 的状态，并同步刷新 workflow_run.status
• 当前规则是：任一节点 failed 则运行 failed；有节点 running 则运行 running；全部节点都为 completed/skipped 则运行 completed
• 当某个 node_run 被更新为 completed 时，runtime-service 还会基于 workflow version 的 DSL 自动查找后继节点，并创建新的 queued 状态 node_run

下一步建议

1. 补齐 V0.1 的 repository / service 层
2. 写第一版 Alembic 初始迁移
3. 接入 PostgreSQL / Redis
4. 增加 Docker Compose
5. 开始实现应用、流程、运行三条主链路
