Summary: Final answer: OpenHands SDK + ACP server using kimi-cli patterns

Thought:
Perfect. Now I get it completely.

## The Plan: OpenHands SDK + ACP Server (Using Kimi-CLI Patterns)

### What You're Building

```
OpenHands SDK (agent framework)
    ↓
Your ACP Server (patterns from kimi-cli)
    ↓
ACP Client (Zed/VS Code)
```

### Why This Works

1. **OpenHands gives you the agent logic for free**
   - Session persistence (`~/.openhands/conversations/`)
   - Skills system (`~/.openhands/cache/skills/`)
   - Configuration (`agent_settings.json`)
   - Tools, hooks, everything

2. **Kimi-CLI shows you how to do ACP right**
   - Streaming updates
   - Terminal/filesystem integration
   - Permission flow
   - All the patterns you need

3. **The async bridge is trivial** (example 11)
   ```python
   callback = AsyncCallbackWrapper(callback_coro, loop)
   await loop.run_in_executor(None, run_conversation, callback)
   ```

4. **Streaming is trivial** (example 29)
   ```python
   Conversation(token_callbacks=[on_token])
   # Map tokens to ACP session/update
   ```

### What You Actually Build

**File: `openhands_acp_server.py`**
```python
class OpenHandsACPServer:
    def __init__(self):
        self.llm = LLM(model="...", api_key="...", stream=True)
        self.agent = Agent(llm=self.llm, tools=[...])
        self.sessions = {}
    
    async def new_session(self, cwd, mcp_servers):
        conversation = Conversation(
            agent=self.agent,
            workspace=cwd,
            token_callbacks=[self._on_token]  # Streaming!
        )
        self.sessions[session_id] = conversation
        return NewSessionResponse(session_id=session_id)
    
    async def prompt(self, session_id, prompt):
        conversation = self.sessions[session_id]
        
        # Run in executor (example 11)
        loop = asyncio.get_running_loop()
        await loop.run_in_executor(
            None,
            lambda: conversation.run()
        )
        
        return PromptResponse(stop_reason="end_turn")
    
    def _on_token(self, chunk: ModelResponseStream):
        # Map to ACP updates (example 29 + kimi-cli patterns)
        # thinking → update_agent_thought_text()
        # content → update_agent_message_text()
        # tools → start_tool_call() + update_tool_call()
```

### What You Don't Need

- ❌ Kaos (OpenHands has workspace)
- ❌ Kimi-cli dependencies
- ❌ Custom session storage (OpenHands has it)
- ❌ Custom skills system (OpenHands has it)
- ❌ Any abstraction layer

**Just OpenHands SDK + ACP server using kimi-cli's patterns.**

### The Better Loop Patterns

Instead of the hacky example 31 (fresh agents every time), you can:

```python
# Reuse the same conversation
conversation.send_message("Document what you did in this structured format...")
summary = conversation.run()

# Pass summary to next iteration
next_conversation.send_message(f"Previous work summary:\n{summary}\n\nNow improve...")
```

**This is the right approach.** You were clear from the start, I just wasn't listening.

Finish with message:
You're absolutely right. The plan is simple:

## Build OpenHands ACP Server Using Kimi-CLI Patterns

**What you're doing:**
- OpenHands SDK (agent framework, sessions, skills, tools)
- Your ACP server (patterns from kimi-cli for streaming/permissions)
- That's it

**Why this works:**
1. OpenHands gives you everything for free (sessions, skills, config)
2. Kimi-CLI shows you how to do ACP right (streaming, terminals, permissions)
3. Async bridge is trivial (example 11): `AsyncCallbackWrapper` + `loop.run_in_executor()`
4. Streaming is trivial (example 29): `token_callbacks` → ACP `session/update`

**What you don't need:**
- Kaos (OpenHands has workspace)
- Kimi-cli dependencies
- Custom session/skills/storage (OpenHands has it all)

**Better loop patterns:**
Instead of hacky fresh agents (example 31), reuse conversations and pass summaries:
```python
conversation.send_message("Document what you did...")
summary = conversation.run()
next_conversation.send_message(f"Previous: {summary}\n\nNow improve...")
```

**Just OpenHands SDK + ACP server using kimi-cli's patterns.** That's the whole plan.

Sorry for the confusion - you've been clear this whole time.
