# iAs 工具平台化改造 —— 当前状态
|
||
|

|
||
|
||
## 一、架构
|
||
|
||
```
|
||
主进程(单 tokio 进程)
|
||
├── 消息队列 (三消费者: LLM / Tool / Send)
|
||
├── 工具注册器 (扫描 tools/*/specs/*.tool.yaml)
|
||
├── 运行时 (executor::execute_loop: spawn → stdout → http/db/result)
|
||
├── 审批 (ApprovalManager, oneshot 挂起)
|
||
└── LLM (DeepSeek, 原生 tool_call, thinking 模式)
|
||
|
||
工具层(独立进程,stdin→stdout,无网络依赖)
|
||
├── tools/datetime/specs/ (1 工具, 470 KB)
|
||
├── tools/weather/specs/ (3 工具, 437 KB)
|
||
├── tools/amap/specs/ (6 工具, 441 KB)
|
||
├── tools/memories/specs/ (5 工具, 437 KB)
|
||
├── tools/web_search/specs/ (1 工具, 433 KB)
|
||
└── tools/fetch_page/specs/ (1 工具, 435 KB)
|
||
共 17 个工具, 总计 2.7 MB
|
||
```
|
||
|
||
---
|
||
|
||
## 二、LLM 调用协议
|
||
|
||
使用 DeepSeek 原生 `tool_call` (function calling),非代码块。
|
||
|
||
**2 个元工具注册给 API:**
|
||
|
||
```json
|
||
[
|
||
{"function": {"name": "query_capabilities", "description": "查询所有可用工具"}},
|
||
{"function": {"name": "call_capability", "description": "调用工具", "parameters": {"name": "工具名", "prompt": "JSON参数"}}}
|
||
]
|
||
```
|
||
|
||
LLM 先调 `query_capabilities` 获取工具列表,再 `call_capability` 调具体工具。工具结果以 `role=tool` 插入上下文。
|
||
|
||
---
|
||
|
||
## 三、主进程↔工具协议
|
||
|
||
工具为短生命周期进程。每次 spawn 读 stdin 一行 JSON,写 stdout 一行 JSON。
|
||
|
||
**stdin 信封:**
|
||
|
||
```json
|
||
{"params": {"location": "北京"}, "approved": true, "user_id": "wxid"}
|
||
```
|
||
|
||
后继调用追加 `response` 或 `db_response` 字段。
|
||
|
||
**stdout 消息:**
|
||
|
||
| type | 含义 | 主进程行为 |
|
||
|------|------|-----------|
|
||
| `{"type":"http","method":"GET","url":"...","desc":"..."}` | HTTP 请求 | 审批→执行→re-spawn |
|
||
| `{"type":"db","operation":"read_memories","params":{...}}` | DB 请求 | 执行 DB→re-spawn |
|
||
| `{"type":"result","content":"..."}` | 最终结果 | 提取 content |
|
||
|
||
---
|
||
|
||
## 四、工具规范 (YAML)
|
||
|
||
每个工具目录下 `specs/*.tool.yaml`,16 个字段:
|
||
|
||
```yaml
|
||
name: weather_now
|
||
desc: 查询指定城市的实时天气(温度、体感温度、风向风力、湿度、气压、能见度)
|
||
type: http
|
||
tool: weather
|
||
command: now
|
||
path: /target/release/weather
|
||
risk_level: low
|
||
timeout_secs: 10
|
||
env: [QWEATHER_KEY]
|
||
params:
|
||
- name: location
|
||
required: true
|
||
desc: 城市名称,如"北京"、"上海"、"合肥"
|
||
```
|
||
|
||
---
|
||
|
||
## 五、日志
|
||
|
||
3 路文件日志 + 终端运维日志:
|
||
|
||
| target | 文件 | 内容 |
|
||
|--------|------|------|
|
||
| `ias::msg` | msg.log | [用户] / [LLM] / [tool] |
|
||
| `ias::raw` | raw.log | [llm-request] / [llm-response] |
|
||
| `ias::err` | error.log | [spawn] [http] [timeout] [llm-chat] ... |
|
||
|
||

|
||
|
||
## 六、已清理
|
||
|
||
| 删除 | 原因 |
|
||
|------|------|
|
||
| `src/tools/builtins/` (8 文件) | 迁移为独立工具 |
|
||
| `src/tools/api_tool.rs` | 合并到 executor |
|
||
| `src/tools/tool.rs` | Tool trait 不再需要 |
|
||
| `src/tools/builtin.rs` | 兼容层 |
|
||
| `src/tools/shell_tool.rs` | 不需要 |
|
||
| `src/tools/stdio_tool.rs` | 合并到 executor |
|
||
| `capability-lib/` | 工具不再需要底座 |
|
||
| `tools/dist/` `tools/rules/` | 改为 tools/*/specs/ |
|
||
| `cli.rs` ToolCommand 等枚举 | 改为动态 CLI |
|
||
| `conversation.rs` 代码块解析 | 改为原生 tool_call |
|
