# ZCLAW v0.2.0 发布实施计划
> **For agentic workers:** REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** 完成 ZCLAW v0.2.0 正式版发布，包含流式响应、MCP 协议、Browser Hand 和工具安全功能。
**Architecture:** 基于 Tauri 的桌面应用，Rust 后端 + React 前端。流式响应通过 Tauri 事件系统传递；MCP 使用 JSON-RPC 2.0 协议；Browser Hand 基于 playwright-rust。
**Tech Stack:** Rust, Tauri 2.x, React 19, TypeScript, playwright-rust, reqwest, tokio
**Spec Document:** `docs/superpowers/specs/2026-03-24-v0.2.0-release-plan-design.md`

## Chunk 1: 流式响应 - 后端 Trait 和类型
### Task 1.1: 定义流式响应类型
**Files:**
- Modify: `crates/zclaw-runtime/src/stream.rs`
- [ ] **Step 1: 添加流式响应类型定义**
在 `stream.rs` 中添加:
```rust
//! Streaming response types
use serde::{Deserialize, Serialize};
/// Stream chunk emitted during streaming
#[derive(Debug, Clone, Serialize, Deserialize)]
#[serde(tag = "type", rename_all = "snake_case")]
pub enum StreamChunk {
/// Text delta
TextDelta { delta: String },
/// Thinking delta (for extended thinking models)
ThinkingDelta { delta: String },
/// Tool use started
ToolUseStart { id: String, name: String },
/// Tool use input delta
ToolUseDelta { id: String, delta: String },
/// Tool use completed
ToolUseEnd { id: String, input: serde_json::Value },
/// Stream completed
Complete {
input_tokens: u32,
output_tokens: u32,
stop_reason: String,
},
/// Error occurred
Error { message: String },
}
/// Streaming event for Tauri emission
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct StreamEvent {
/// Session ID for routing
pub session_id: String,
/// Agent ID for routing
pub agent_id: String,
/// The chunk content
pub chunk: StreamChunk,
}
impl StreamEvent {
pub fn new(session_id: impl Into<String>, agent_id: impl Into<String>, chunk: StreamChunk) -> Self {
Self {
session_id: session_id.into(),
agent_id: agent_id.into(),
chunk,
}
}
}
```
- [ ] **Step 2: 验证编译通过**
Run: `cd crates/zclaw-runtime && cargo check`
Expected: 编译成功，无错误
- [ ] **Step 3: 提交类型定义**
```bash
git add crates/zclaw-runtime/src/stream.rs
git commit -m "feat(runtime): add streaming response types
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>"
```
---
### Task 1.2: 扩展 LlmDriver Trait
**Files:**
- Modify: `crates/zclaw-runtime/src/driver/mod.rs`
- [ ] **Step 1: 添加 stream 方法到 trait**
在 `LlmDriver` trait 中添加方法:
```rust
use futures::Stream;
use std::pin::Pin;
use crate::stream::StreamChunk;
/// LLM Driver trait - unified interface for all providers
#[async_trait]
pub trait LlmDriver: Send + Sync {
/// Get the provider name
fn provider(&self) -> &str;
/// Send a completion request
async fn complete(&self, request: CompletionRequest) -> Result<CompletionResponse>;
/// Send a streaming completion request
/// Returns a stream of chunks
fn stream(
&self,
request: CompletionRequest,
) -> Pin<Box<dyn Stream<Item = Result<StreamChunk>> + Send + '_>>;
/// Check if the driver is properly configured
fn is_configured(&self) -> bool;
}
```
- [ ] **Step 2: 在 Cargo.toml 添加 futures 依赖**
检查 `crates/zclaw-runtime/Cargo.toml` 是否有 `futures` 依赖，如果没有则添加:
```toml
futures = "0.3"
```
- [ ] **Step 3: 验证编译 (预期失败)**
Run: `cd crates/zclaw-runtime && cargo check 2>&1`
Expected: 编译失败，因为各驱动未实现 `stream()` 方法
- [ ] **Step 4: 提交 trait 扩展**
```bash
git add crates/zclaw-runtime/src/driver/mod.rs crates/zclaw-runtime/Cargo.toml
git commit -m "feat(runtime): add stream() method to LlmDriver trait
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>"
```

```rust
use futures::{Stream, StreamExt};
use crate::stream::StreamChunk;
use std::pin::Pin;
/// SSE event from Anthropic API
#[derive(Debug, Deserialize)]
struct AnthropicStreamEvent {
#[serde(rename = "type")]

Expected: 查看现有实现结构
- [ ] **Step 2: 添加 OpenAI 流式实现**
在 `openai.rs` 中添加类似的 stream 方法，适配 OpenAI 的 SSE 格式:
```rust
fn stream(
&self,
request: CompletionRequest,
) -> Pin<Box<dyn Stream<Item = Result<StreamChunk>> + Send + '_>> {
Box::pin(async_stream::stream! {
let stream_request = self.build_api_request(&request);

## Chunk 3: 流式响应 - LoopRunner 和 Tauri 集成
### Task 3.1: 实现 LoopRunner 流式循环
**Files:**
- Modify: `crates/zclaw-runtime/src/loop_runner.rs`
- [ ] **Step 1: 修改 run_streaming 方法**
替换现有的 TODO 占位符:
```rust
use crate::stream::{StreamChunk, StreamEvent};
use tauri::{AppHandle, Emitter};
/// Run the agent loop with streaming
pub async fn run_streaming(
&self,
session_id: SessionId,
input: String,
app_handle: Option<AppHandle>,
) -> Result<mpsc::Receiver<LoopEvent>> {
let (tx, rx) = mpsc::channel(100);
// Add user message to session
let user_message = Message::user(input);
self.memory.append_message(&session_id, &user_message).await?;
// Get all messages for context
let messages = self.memory.get_messages(&session_id).await?;
// Build completion request
let request = CompletionRequest {
model: self.model.clone(),
system: self.system_prompt.clone(),
messages,
tools: self.tools.definitions(),
max_tokens: Some(self.max_tokens),
temperature: Some(self.temperature),
stop: Vec::new(),
stream: true,
};
// Clone necessary data for the async task
let session_id_str = session_id.to_string();
let agent_id_str = self.agent_id.to_string();
let memory = self.memory.clone();
let driver = self.driver.clone();
tokio::spawn(async move {
let mut full_response = String::new();
let mut input_tokens = 0u32;
let mut output_tokens = 0u32;
let mut stream = driver.stream(request);
use futures::StreamExt;
while let Some(chunk_result) = stream.next().await {
match chunk_result {
Ok(chunk) => {
// Emit to Tauri if available
if let Some(ref handle) = app_handle {
let event = StreamEvent::new(&session_id_str, &agent_id_str, chunk.clone());
let _ = handle.emit("stream:chunk", event);
}
// Track response and tokens
match &chunk {
StreamChunk::TextDelta { delta } => {
full_response.push_str(delta);
let _ = tx.send(LoopEvent::Delta(delta.clone())).await;
}
StreamChunk::ThinkingDelta { delta } => {
let _ = tx.send(LoopEvent::Delta(format!("[思考] {}", delta))).await;
}
StreamChunk::ToolUseStart { name, .. } => {
let _ = tx.send(LoopEvent::ToolStart {
name: name.clone(),
input: serde_json::Value::Null,
}).await;
}
StreamChunk::ToolUseEnd { input, .. } => {
let _ = tx.send(LoopEvent::ToolEnd {
name: String::new(),
output: input.clone(),
}).await;
}
StreamChunk::Complete { input_tokens: it, output_tokens: ot, .. } => {

}
}
Err(e) => {
let _ = tx.send(LoopEvent::Error(e.to_string())).await;
}
}
}
// Save assistant message to memory
let assistant_message = Message::assistant(full_response.clone());
let _ = memory.append_message(&session_id, &assistant_message).await;
// Send completion event
let _ = tx.send(LoopEvent::Complete(AgentLoopResult {
response: full_response,
input_tokens,
output_tokens,
iterations: 1,
})).await;
});
Ok(rx)
}
```
- [ ] **Step 2: 添加 tauri 依赖 (可选)**
如果需要在 runtime crate 中使用 tauri，在 `Cargo.toml` 添加:
```toml
[dependencies]
tauri = { version = "2", optional = true }
[features]
default = []
tauri = ["dep:tauri"]
```
- [ ] **Step 3: 验证编译通过**
Run: `cd crates/zclaw-runtime && cargo check`

```rust
use zclaw_runtime::{AgentLoop, LoopEvent};
use tauri::{AppHandle, Emitter};
#[tauri::command]
async fn chat_stream(
agent_id: String,
session_id: String,
message: String,
app: AppHandle,
state: State<'_, KernelState>,
) -> Result<(), String> {
let agent_loop = state.kernel
.get_agent_loop(&agent_id)
.await
.map_err(|e| e.to_string())?;
let session: zclaw_types::SessionId = session_id.parse()
.map_err(|_| "Invalid session ID")?;
let mut rx = agent_loop
.run_streaming(session, message, Some(app))
.await
.map_err(|e| e.to_string())?;
// The streaming is handled via Tauri events in run_streaming
// This command just initiates the stream
Ok(())
}
```
- [ ] **Step 2: 注册命令**
在 `lib.rs` 的 `invoke_handler` 中注册:
```rust
.invoke_handler(tauri::generate_handler![
// ... existing commands
chat_stream,
])
```
- [ ] **Step 3: 验证编译通过**
Run: `cd desktop && pnpm tauri build --debug 2>&1 | head -50`
Expected: 编译开始，检查错误

### Task 4.3: 更新聊天 UI 组件
**Files:**
- Modify: `desktop/src/components/ChatPanel.tsx` (或对应组件)
- [ ] **Step 1: 添加流式发送逻辑**
在发送消息的处理中添加流式判断:
```tsx
const handleSend = async (content: string) => {
if (useStreaming) {
await chatStore.sendStreamingMessage(content);
} else {
await chatStore.sendMessage(content);
}
};
```
- [ ] **Step 2: 添加流式指示器**
```tsx
{chatStore.isStreaming && (
<div className="flex items-center gap-2 text-sm text-gray-500">
<span className="animate-pulse">●</span>
正在生成...
</div>
)}
```
- [ ] **Step 3: 验证编译通过**
Run: `cd desktop && pnpm tsc --noEmit`
Expected: 无类型错误
- [ ] **Step 4: 提交 UI 更新**
```bash
git add desktop/src/components/ChatPanel.tsx
git commit -m "feat(frontend): add streaming UI indicators
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>"
```
---
## 里程碑 M1: 流式响应完成
- [ ] **验证流式响应功能**
Run: `pnpm desktop` 启动应用
Expected:
1. 发送消息后能看到逐字显示
2. 流式过程中有指示器
3. 完成后状态正确
- [ ] **提交里程碑**
```bash
git tag v0.2.0-m1-streaming
git push origin v0.2.0-m1-streaming
```

- [ ] **Step 2: 添加 base64 依赖**
在 `crates/zclaw-hands/Cargo.toml` 添加:
```toml
base64 = "0.22"
```
- [ ] **Step 3: 更新 mod.rs 导出**
```rust
// crates/zclaw-hands/src/hands/mod.rs
//! Hands - Autonomous capabilities
mod whiteboard;
mod slideshow;
mod speech;
mod quiz;
mod browser;
pub use whiteboard::*;
pub use slideshow::*;
pub use speech::*;
pub use quiz::*;
pub use browser::*;
```
- [ ] **Step 4: 在 ZclawError 中添加 HandError 变体**
确保 `crates/zclaw-types/src/error.rs` 有:
```rust
HandError(String),
```
- [ ] **Step 5: 验证编译通过**
Run: `cd crates/zclaw-hands && cargo check`
Expected: 编译成功
- [ ] **Step 6: 提交 Browser Hand 实现**
