Now I have all the information I need. The `ClaudeCodeOptions` doesn't have a `cli_path` parameter - it uses the Claude Code CLI that's installed. Let me update the spec_chat_session.py to use the correct imports and API.

Key changes needed:
1. Change imports from `claude_agent_sdk` to `claude_code_sdk`
2. Use `ClaudeCodeOptions` instead of `ClaudeAgentOptions`
3. Remove `cli_path` parameter (SDK finds Claude automatically)
4. Check how to receive responses from the client


Now let me update the spec_chat_session.py with the correct SDK imports and API.

Good. Now I need to remove the unused `shutil` import and also check if there's a `query` or `receive_response` method on the client. Let me also look at how the client sends messages and receives responses.


Bash

python -c "from claude_code_sdk import ClaudeSDKClient; c = ClaudeSDKClient(); print([m for m in dir(c) if not m.startswith('_')])"

Check ClaudeSDKClient methods


['connect', 'disconnect', 'get_server_info', 'interrupt', 'options', 'query', 'receive_messages', 'receive_response']


The client has `query`, `receive_messages`, and `receive_response`. Let me check how these work.


python -c "from claude_code_sdk import ClaudeSDKClient; help(ClaudeSDKClient.query)" 2>&1 | head -40

Check query method


Help on function query in module claude_code_sdk.client:

async query(
    self,
    prompt: str | collections.abc.AsyncIterable[dict[str, typing.Any]],
    session_id: str = 'default'
) -> None
    Send a new request in streaming mode.

    Args:
        prompt: Either a string message or an async iterable of message dictionaries
        session_id: Session identifier for the conversation


So `query()` sends the request and `receive_response()` gets the response. That's what the current code does. Let me also check `receive_response`.


python -c "from claude_code_sdk import ClaudeSDKClient; help(ClaudeSDKClient.receive_response)" 2>&1 | head -40

Check receive_response method


Help on function receive_response in module claude_code_sdk.client:

async receive_response(self) -> collections.abc.AsyncIterator[claude_code_sdk.types.UserMessage | claude_code_sdk.types.AssistantMessage | claude_code_sdk.types.SystemMessage | claude_code_sdk.types.ResultMessage | claude_code_sdk.types.StreamEvent]
    Receive messages from Claude until and including a ResultMessage.

    This async iterator yields all messages in sequence and automatically terminates
    after yielding a ResultMessage (which indicates the response is complete).
    It's a convenience method over receive_messages() for single-response workflows.

    **Stopping Behavior:**
    - Yields each message as it's received
    - Terminates immediately after yielding a ResultMessage
    - The ResultMessage IS included in the yielded messages
    - If no ResultMessage is received, the iterator continues indefinitely

    Yields:
        Message: Each message received (UserMessage, AssistantMessage, SystemMessage, ResultMessage)

    Example:
        ```python
        async with ClaudeSDKClient() as client:
            await client.query("What's the capital of France?")

            async for msg in client.receive_response():
                if isinstance(msg, AssistantMessage):
                    for block in msg.content:
                        if isinstance(block, TextBlock):
                            print(f"Claude: {block.text}")
                elif isinstance(msg, ResultMessage):
                    print(f"Cost: ${msg.total_cost_usd:.4f}")
                    # Iterator will terminate after this message
        ```

    Note:
        To collect all messages: `messages = [msg async for msg in client.receive_response()]`
        The final message in the list will always be a ResultMessage.


The API looks compatible with what I have in the code. The issue is probably that the SDK couldn't find the Claude CLI. Let me also check the unused shutil import and remove it since we're no longer using `shutil.which("claude")`.


Let me also check what happens when we look at receive messages types.


python -c "from claude_code_sdk import AssistantMessage, TextBlock, ToolUseBlock, UserMessage, ToolResultBlock; print('Types OK')"

Check message types


Types OK


Good, the types are correct. Now let me remove the unused `shutil` import from spec_chat_session.py and fix up the code.

Good. Now let me verify the syntax and check if the backend will start. Also, the error "Failed to start Claude Code:" suggests that the Claude CLI might not be in the PATH. Let me check if the Claude CLI is available.


Bash

where claude 2>&1 || which claude 2>&1 || echo "Claude CLI not found in PATH"

Check if Claude CLI is in PATH


The Claude CLI is available. Let me verify the syntax and then try to figure out why the SDK is failing to start. The error might be in the SDK's attempt to start Claude Code.


python -m py_compile "C:/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/app/services/spec_chat_session.py" && echo "Syntax OK"

Verify syntax


Syntax OK


The syntax is fine. The issue is likely that the SDK is failing to start Claude Code properly. Let me create a simple test script to see what the actual error is.


Let me test the SDK directly to see the full error.


python -c "

Test SDK connection


Client connected successfully!


Interesting, the SDK connects successfully when tested directly. The issue might be with how it's being used in the context of the FastAPI server, or maybe the project directory doesn't exist or has permission issues. Let me check the guru-connect project path in the database.


The SDK works. The issue might be with the project path. Let me check what the guru-connect project path is.


sqlite3 "C:/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/autocoder.db" "SELECT name, path FROM projects WHERE name='guru-connect';" 2>&1

for row in cursor.fetchall():
    print(row[0])
conn.close()
"

List database tables


The database appears to be empty. Let me look for a different database file or check the config.


ls -la "C:/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/"*.db 2>&1 || echo "No db files found"

Find database files

There's a different database: `autocoder_plus.db`. Let me check that one.


python -c "
import sqlite3
conn = sqlite3.connect('C:/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/autocoder_plus.db')

Tables:

The project exists in the database with the path `C:/Users/MikeSwanson/claude-projects/guru-connect`. Let me check if that directory exists.

The SDK works perfectly with the project directory. The issue must be something specific to how it's being called in the FastAPI context. Let me check if maybe there's an issue with the settings file path or the async context.Let me check the backend logs more carefully. Maybe we can enable more verbose logging.


The SDK works. The issue might be in how the FastAPI server is calling it or with the settings file. Let me check the settings file that was written.


Check settings file


The settings file looks fine. Let me test with the settings file included.

Test with settings file


Client connected with settings!


Everything works when tested standalone. The issue must be something specific to the FastAPI async context. Let me check if maybe the issue is the error being truncated or if there's a version issue with how asyncio is being handled.

Let me also check if maybe we need to use `asyncio.to_thread` or some other approach for the SDK calls within FastAPI.

Actually, let me re-check the error message. The user saw:
"Failed to initialize Claude: Failed to start Claude Code:"

This suggests the SDK started connecting but something went wrong. Let me check if perhaps the issue is that the connection is being made but then a subsequent operation is failing.

Let me also check if there's an issue with running nested event loops or something like that in the FastAPI context.


Let me check if there's a FastAPI/asyncio compatibility issue. Let me update the spec chat session to add better error logging.

Let me add more detailed error logging to understand what's happening. The error "Failed to start Claude Code:" suggests the Claude CLI is returning an error. Let me check if perhaps we need to add debug_stderr to capture the actual error output.


Let me add debug output to capture the actual SDK error.
