Good. Now I need to export `check_claude_cli` from the services __init__.py. Let me also update the TodoWrite to track progress.

Now let me test the diagnostic endpoint to see if the Claude CLI is available. I'll use curl to hit the health endpoint.


Now let me test the diagnostic endpoint to check if Claude CLI is available:


Bash

curl -s http://localhost:8000/api/spec/health 2>/dev/null || echo "Server not running or endpoint not available"

Test Claude CLI health endpoint


Command running in background with ID: bba1dbf. Output is being written to: C:\Users\MIKESW~1\AppData\Local\Temp\claude\C--Users-MikeSwanson\tasks\bba1dbf.output


<retrieval_status>timeout</retrieval_status>

<task_id>bba1dbf</task_id>

<task_type>local_bash</task_type>

<status>running</status>

Test Claude CLI health endpoint


The curl command is timing out. The server may not be running. Let me check if the backend server is running.


Let me check if the backend server is running:


tasklist /FI "IMAGENAME eq python.exe" | head -20

Check for running Python processes


ERROR: Invalid argument/option - 'C:/Program Files/Git/FI'.
Type "TASKLIST /?" for usage.


Windows doesn't have head command by default. Let me try a different approach.


Check for running Python processes


python.exe                  114624 Console                    1     10,864 K
python3.13.exe              120164 Console                    1     41,940 K
python3.13.exe               93228 Console                    1     97,076 K


There are Python processes running, but I'm not sure if the backend server is one of them. Let me check if the `claude` command is available in the PATH directly.


Let me directly check if claude CLI is available:


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

Check if claude CLI is in PATH


Claude CLI is in the PATH. Let me verify it works:


Claude CLI is found. Let me verify it works:


Check Claude CLI version


2.1.3 (Claude Code)


Claude CLI is working. So the issue is not with the CLI itself but something else in the FastAPI context. Let me check if there's something wrong with how we're using the SDK. Looking at the claude-code-sdk, I should check how it expects to be used.

Actually, looking at the autocoder-master project, let me see how they use it there.


The Claude CLI is available and working (v2.1.3). Let me check how the original autocoder-master project uses the SDK:


Let me read the original file to see how they use the SDK.
