I'll use a different approach using Task subagent to edit this file:


Task

Update routers __init__.py

Prompt:
Please update the file at C:/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/app/routers/__init__.py

The file needs to:
1. Add the import: from .git import router as git_router
2. Add "git_router" to the __all__ list

Read the file first, then edit it to add the git router import and export.


The file has been successfully updated. Here is a summary of the changes made to `C:/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/app/routers/__init__.py`:

1. **Added import statement** on line 15:
   ```python
   from .git import router as git_router
   ```

2. **Added "git_router" to the `__all__` list** (now the last item in the list):
   ```python
   __all__ = [
       "projects_router",
       "websocket_router",
       "agents_router",
       "features_router",
       "permissions_router",
       "spec_router",
       "infrastructure_router",
       "git_router",  # <-- Added
   ]
   ```

The git router is now properly imported and exported from the routers package.

Prompt:
Please update the file at C:/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/app/routers/__init__.py

The file needs to:
1. Add the import: from .git import router as git_router
2. Add "git_router" to the __all__ list

Read the file first, then edit it to add the git router import and export.


Now let me update main.py to include the git router:


Edit

from .routers import projects_router, websocket_router, agents_router, features_router, permissions_router, spec_router, infrastructure_router

from .routers import projects_router, websocket_router, agents_router, features_router, permissions_router, spec_router, infrastructure_router, git_router


Task

Update main.py git router

Prompt:
Please update the file at C:/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/app/main.py

Make these changes:
1. Add git_router to the import from .routers (line 22): it should become:
   from .routers import projects_router, websocket_router, agents_router, features_router, permissions_router, spec_router, infrastructure_router, git_router

2. Add a line to include the git_router after line 142 (after infrastructure_router):
   app.include_router(git_router)

Read the file first, then edit it.


I'm facing a race condition issue. It appears there's another agent or process that's continuously modifying this file. Let me inform you of the exact changes you need to make manually:

**Changes needed for `C:/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/app/main.py`:**

1. **Line 22** - Update the import statement to add `git_router`:

   Change:
   ```python
   from .routers import projects_router, websocket_router, agents_router, features_router, permissions_router, spec_router, infrastructure_router
   ```

   To:
   ```python
   from .routers import projects_router, websocket_router, agents_router, features_router, permissions_router, spec_router, infrastructure_router, git_router
   ```

2. **After line 142** (after `app.include_router(infrastructure_router)`) - Add a new line:
   ```python
   app.include_router(git_router)
   ```

The file is being continuously modified by another process (likely a server with auto-reload enabled or another Claude agent working on the same file), which is preventing me from making edits. You may need to temporarily stop the other process or make these changes manually.

Now let me try using a specific Task agent that focuses on file edits:


Task

Edit main.py add git_router

Prompt:
Read then edit C:/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/app/main.py

Make exactly 2 edits:

1. On line 22, change:
   from .routers import projects_router, websocket_router, agents_router, features_router, permissions_router, spec_router, infrastructure_router

   To:
   from .routers import projects_router, websocket_router, agents_router, features_router, permissions_router, spec_router, infrastructure_router, git_router

2. After line 142 which says "app.include_router(infrastructure_router)", add a new line:
   app.include_router(git_router)

Use the Read tool first, then use Edit tool to make these specific changes. If the Edit tool fails with "File has been unexpectedly modified", re-read the file and try again.


The file is being continuously modified. This is likely caused by:
1. A running uvicorn server with `--reload` that touches the file
2. Another Claude agent working on this file simultaneously

**You need to stop the process that's modifying this file** before I can make the edits. This could be:
- Stop any running `uvicorn` or development server for this project
- Close any other Claude Code sessions that might be editing this file

Once you've done that, let me know and I'll retry the edits. Alternatively, you could manually make these two edits:

**Edit 1 (Line 22):** Change:
```python
from .routers import projects_router, websocket_router, agents_router, features_router, permissions_router, spec_router, infrastructure_router
```
To:
```python
from .routers import projects_router, websocket_router, agents_router, features_router, permissions_router, spec_router, infrastructure_router, git_router
```

**Edit 2 (After Line 142):** After `app.include_router(infrastructure_router)`, add:
```python
app.include_router(git_router)
```

agentId: ac31746 (for resuming to continue this agent's work if needed)

Prompt:
Read then edit C:/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/app/main.py

Make exactly 2 edits:

1. On line 22, change:
   from .routers import projects_router, websocket_router, agents_router, features_router, permissions_router, spec_router, infrastructure_router

   To:
   from .routers import projects_router, websocket_router, agents_router, features_router, permissions_router, spec_router, infrastructure_router, git_router

2. After line 142 which says "app.include_router(infrastructure_router)", add a new line:
   app.include_router(git_router)

Use the Read tool first, then use Edit tool to make these specific changes. If the Edit tool fails with "File has been unexpectedly modified", re-read the file and try again.


The server is auto-reloading and modifying the file. Let me check what servers are running and try a different approach - I'll create a small Python script to make the edit:


Bash

curl -s http://127.0.0.1:8105/health 2>/dev/null || echo "No server on 8105"

Check if server running on 8105


There's a server running on port 8105. The server has `--reload` which is watching for file changes. Let me check the background task and look at another port for testing:

I see the server is running. Let me start a new server on a different port (8106) that includes the git router. First I'll create the new start script and work from there:
