The user sent /stats which is a Claude Code command. But I should continue with the task at hand.

The code is now updated with stderr capture. The user needs to restart the server to pick up the changes. Let me also check if the server is running with --reload which would auto-pickup changes.


The code now has better error logging with stderr capture. **Please restart the backend server** to apply the changes, then try the interview again. The error message should now show more details about what's failing.

If you're running uvicorn without `--reload`, you'll need to manually restart it.


The user is asking for stats using the /stats command. This is a Claude Code CLI command that shows usage statistics. I should not try to handle this myself - it's a built-in command that the CLI handles directly. I'll just acknowledge and wait for the user's next input.


The `/stats` command is handled by Claude Code directly. I'll wait for the result.

In the meantime - I've updated the code with better error logging. Once you restart the backend server and try the interview again, we should see a more detailed error message that will help identify the root cause.

The error message now shows "Stderr:" but it's empty. The stderr capture isn't getting any output. This suggests the issue is happening before the CLI even starts outputting to stderr.

Let me think about what could cause "Failed to start Claude Code:" with no stderr output:
1. The subprocess fails to spawn at all
2. There's a permission issue
3. The CLI path might not work properly when called as a subprocess
4. There could be an issue with how the SDK spawns the process

Let me check the SDK source to understand how it spawns the subprocess. But first, let me try a different approach - let me check if there's something specific about running the CLI from within the FastAPI process.

Actually, let me check if there's an issue with the event loop in FastAPI. The SDK might be having trouble with the async subprocess handling in the uvicorn context.

Let me also verify that the SDK version we have actually uses subprocess correctly. Maybe there's a bug or compatibility issue.

Let me try running the exact same test from within a FastAPI-like async context to see if that's the issue.


Stderr is empty, so the CLI isn't even starting. Let me check if there's an event loop issue with the subprocess in FastAPI's context:

Test SDK without explicit cli_path


Testing without explicit cli_path...
Client created (no cli_path)
Success without cli_path!


Interesting! It works without the explicit `cli_path`. Maybe there's an issue with the explicit cli_path. Let me check if the SDK has a different way to find the CLI or if there's something wrong with the path we're providing.


It works without `cli_path`. Let me check if the path format is the issue:


python -c "
import shutil
cli = shutil.which('claude')
print(f'CLI path: {cli}')
print(f'Type: {type(cli)}')
print(f'Repr: {repr(cli)}')
"

Check CLI path format


CLI path: C:\Users\MikeSwanson\.local\bin\claude.EXE
Type: <class 'str'>
Repr: 'C:\\Users\\MikeSwanson\\.local\\bin\\claude.EXE'


The path looks fine. Let me just remove the `cli_path` parameter since the SDK can find it automatically. The original autocoder used `cli_path` to work around a bundled runtime issue, but if the SDK finds it automatically, we don't need it.


The SDK finds the CLI automatically. Let me remove the `cli_path` parameter since it's causing issues:

Good, I removed the cli_path parameter. The SDK should find the CLI automatically now. Restart the server and test again.


Removed `cli_path` - the SDK finds the CLI automatically. **Restart the backend server** and try again.


same

Create spec_chat_session service

Copy skill files and templates

Update services __init__.py

Update spec router to use Claude SDK

Switch to claude-agent-sdk package

Test full interview flow


Still the same error. Let me test directly what happens in the FastAPI context. Maybe there's something about how uvicorn runs that affects subprocess spawning. Let me check if the issue is specific to the uvicorn process environment.

Let me also check if maybe the SDK bundled with claude-agent-sdk has its own CLI and that's what's failing.

Received: {

}


Still empty stderr. Let me check if maybe the SDK is using its own bundled CLI instead of the system one. Let me look at how the SDK finds the CLI.

Actually, wait - the SDK version 0.1.19 might have a bundled Claude CLI that's different from the system one. Let me check if there's a bundled CLI in the SDK package directory.


Let me check if the SDK has a bundled CLI that might be causing issues:


python -c "
import claude_agent_sdk
import os
sdk_path = os.path.dirname(claude_agent_sdk.__file__)
print(f'SDK path: {sdk_path}')
for root, dirs, files in os.walk(sdk_path):
    for f in files:
        if 'claude' in f.lower() or f.endswith('.exe'):
            print(os.path.join(root, f))
"

Check SDK directory for bundled CLI


The SDK has a bundled `claude.exe` at `_bundled/claude.exe`. This is probably the one causing issues - the bundled version might not work properly on Windows. The original autocoder code uses `cli_path` to override this with the system-installed CLI.

But when I pass `cli_path`, it fails. And without `cli_path`, it uses the bundled one which also fails.

Let me check if the bundled CLI works directly:


Found the issue - the SDK has a bundled CLI. Let me test if it works:


Test bundled CLI


2.1.1 (Claude Code)


The bundled CLI works. Version 2.1.1 vs system version 2.1.3. Let me check what happens when running the SDK from within the FastAPI process specifically. Maybe there's an environment variable or PATH issue.Let me try to understand why passing cli_path causes issues. Let me test with the explicit path to the bundled CLI:

Test with explicit bundled CLI path

Success with bundled CLI path!


OK so both:1. Without cli_path (uses bundled) - works in standalone test
2. With explicit bundled cli_path - works in standalone testBut in FastAPI it fails. Let me check if there's something about the FastAPI/uvicorn environment that's different. Maybe it's the working directory or some environment variable.

Let me check if the server is actually running the updated code. Maybe there's a caching issue or the server hasn't actually restarted.

Let me add a very distinctive marker to the error message so we can be sure the new code is running.


Both work in standalone. The issue must be FastAPI-specific. Let me add a distinctive marker to confirm the code is reloaded:

The server is not responding. The user needs to restart the backend server. Let me tell them to restart it and then try the interview again.


The server is not running. Please restart the backend server:

```bash
cd C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend
python -m uvicorn app.main:app --reload --port 8000
```

Then try the interview again. The error message should now show `[v3]` if the new code is loaded.

The task notification is just confirming the previous task completed. I already retrieved the output which showed "Server not responding". The user needs to restart the server. Let me wait for them to do that.


I already checked that output - the server is down. Please restart the backend server and try the interview again.


[v3] Failed to initialize Claude: Failed to start Claude Code: Stderr: CWD: C:\Users\MikeSwanson\claude-projects\guru-connect

Good, now we can see the new code is running (v3 marker). The error is still the same - "Failed to start Claude Code:" with empty stderr. The CWD is correct.

The issue is that the SDK's bundled CLI is failing to start, but we're not getting any stderr output. Let me think about what could cause this...

Since the standalone tests work but FastAPI doesn't, the difference must be in:
1. Environment variables
2. Working directory of the uvicorn process
3. How the subprocess is spawned (maybe different event loop behavior)
4. Something about how uvicorn handles subprocesses

Let me check if we can run a simple subprocess from within FastAPI to see if that works. But first, let me try a different approach - what if we use `subprocess.PIPE` for stderr instead of StringIO?

Actually, looking at the SDK, the `stderr` parameter might expect something different. Let me check what type it expects.

Actually, let me try adding some debug output before the client creation to see what's happening. And let me also check if there's a sandbox issue or permission issue.

Wait - looking at the settings file we create, we have `"sandbox": {"enabled": False}`. But the SDK might have its own sandbox settings. Let me check if there's a sandbox parameter in ClaudeAgentOptions.

Looking at the parameters I listed earlier, there is a `sandbox` parameter! Let me try explicitly disabling the sandbox in the options.


Good, the new code is running. The SDK has a `sandbox` parameter - let me try explicitly disabling it:
