Now I have a good understanding of the system. Let me summarize what I've learned:

1. **Backend (FastAPI)**: Located at `backend/app/`
   - `routers/projects.py` - Project CRUD operations
   - `routers/spec.py` - Spec management (get/update/history/rollback)
   - `routers/websocket.py` - WebSocket handler for spec creation chat

2. **Frontend (React)**: Located at `autocoder-master/ui/`
   - `NewProjectModal.tsx` - Multi-step wizard for creating projects:
     1. Enter project name
     2. Select project folder (appends project name to path)
     3. Choose spec method (Claude or manual)
     4a. If Claude: Show SpecCreationChat
     4b. If manual: Create project and close
   - `SpecCreationChat.tsx` - Full chat interface for spec creation with Claude
   - `FolderBrowser.tsx` - Server-side filesystem browser

3. **Key insight**: The current flow assumes you're creating a NEW folder for the project. For importing, we need to:
   - Browse to an existing folder (not append project name)
   - Analyze what's already there
   - Start the spec interview with context about the existing codebase

Now let me plan the implementation:

**Feature: Import Existing Project**

1. **UI Changes**:
   - Add a third option in the initial view (or a separate entry point): "Import Existing Project"
   - Modify FolderBrowser behavior to select the folder itself (not append project name)
   - Start spec creation chat with a flag indicating it's an import

2. **Backend Changes**:
   - Add endpoint to analyze an existing folder (get file structure, detect tech stack)
   - Modify spec creation WebSocket to accept "import mode" with context
   - Pass codebase context to Claude at start of interview

The import workflow would have the user select an existing folder like GuruConnect, optionally rename it as a project, then the system scans the directory structure and tech stack before initiating the spec interview with Claude using that codebase context. This requires coordinated changes across both the frontend and backend to properly analyze and contextualize existing projects during the spec creation process.


I've got a good understanding of the system now. This is a meaningful feature that touches both frontend and backend. Let me outline what's involved:

**Import Existing Project Feature**

**Current Flow** (new project):
1. Enter project name → 2. Select parent folder (appends name) → 3. Claude interview → 4. Start agent

**Import Flow** (your request):
1. Select existing folder → 2. Set project name (default to folder name) → 3. Analyze codebase → 4. Claude interview with context → 5. Start agent

**Changes Needed:**

| Component | Changes |
|-----------|---------|
| **UI - NewProjectModal** | Add "Import Existing" option alongside "Create New" |
| **UI - FolderBrowser** | Mode to select folder itself (not append name) |
| **Backend - projects.py** | `POST /api/projects/import` endpoint |
| **Backend - New endpoint** | Analyze folder (detect stack, list files) |
| **Backend - websocket.py** | Accept import context, pass to Claude |
| **Spec interview prompt** | Include codebase summary so Claude knows what exists |

Would you like me to enter plan mode to design this in detail, or should I start implementing? I'd estimate this as a moderate feature - maybe 4-6 files to modify/create.


yep


The user said "yep" which I interpret as approval to proceed. They could mean either entering plan mode or starting implementation. Given the complexity of this feature (touching multiple files across frontend and backend), I should enter plan mode to design it properly before implementing.


Entered plan mode. You should now focus on exploring the codebase and designing an implementation approach.

In plan mode, you should:
1. Thoroughly explore the codebase to understand existing patterns
2. Identify similar features and architectural approaches
3. Consider multiple approaches and their trade-offs
4. Use AskUserQuestion if you need to clarify the approach
5. Design a concrete implementation strategy
6. When ready, use ExitPlanMode to present your plan for approval

Remember: DO NOT write or edit any files yet. This is a read-only exploration and planning phase.


I'm now in plan mode. Let me explore the codebase more thoroughly to understand:
1. The existing project creation flow in detail
2. How the spec creation WebSocket works
3. The folder browser implementation
4. What context/analysis capabilities exist

I'll launch a few explore agents to investigate different aspects of the codebase.

Perfect! I now have a comprehensive understanding of the project creation flow. Let me compile my findings into a clear report.

## Autocoder+ Project Creation Flow Analysis

I've analyzed all the key components of the project creation wizard. Here's a detailed breakdown:

### 1. NewProjectModal.tsx - Multi-Step Wizard State Management

**File:** `C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\autocoder-master\ui\src\components\NewProjectModal.tsx`

**Step Flow:**
1. **"name"** - User enters project name
2. **"folder"** - User selects project location (triggers FolderBrowser modal)
3. **"method"** - User chooses setup method (Claude or Manual)
4. **"chat"** (if Claude selected) - Full-screen SpecCreationChat for interactive setup
5. **"complete"** - Success confirmation with auto-navigation

**Key State Variables:**
- `step: Step` - Current workflow step
- `projectName` - Validated with regex `^[a-zA-Z0-9_-]+$`
- `projectPath` - Full path calculated as `${selectedFolderPath}/${projectName}` (lines 69-73)
- `specMethod` - 'claude' or 'manual'
- `initializerStatus` - Tracks agent startup: 'idle' | 'starting' | 'error'

**Name Step (lines 51-67):**
- Validates non-empty and alphanumeric + hyphens/underscores
- Advances to folder selection on submit

**Folder Step (lines 69-74):**
- `handleFolderSelect()` appends project name to selected path
- Path concatenation: `${path}/${projectName.trim()}` (important: appends project name here)
- Moves to method selection

**Method Selection (lines 80-118):**
- **Manual mode**: Creates project immediately with `createProject.mutateAsync()`, shows completion screen
- **Claude mode**: Creates project, then displays chat interface for spec definition
- Both pass `specMethod` parameter to API

**Completion & Agent Startup (lines 120-143):**
- After spec completion, calls `startAgent(projectName, yoloMode)`
- 1500ms delay before navigation to new project

---

### 2. FolderBrowser.tsx - Filesystem Navigation Component

**File:** `C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\autocoder-master\ui\src\components\FolderBrowser.tsx`

**API Integration:**
- Uses React Query (`useQuery`) with `api.listDirectory(currentPath)` (lines 42-45)
- Query key: `['filesystem', 'list', currentPath]` - refetches when path changes

**Data Returned (DirectoryListResponse):**
```typescript
{
  current_path: string
  parent_path: string | null
  entries: DirectoryEntry[]  // Objects with: { name, path, is_directory, has_children }
  drives: DriveInfo[] | null  // Windows drive list: { letter, label, available? }
}
```

**Navigation Features:**
- **Drive selection** (Windows only) - Lines 68-70: `handleDriveSelect()` navigates to `${drive.letter}:/`
- **Breadcrumb navigation** - Lines 110-135: `getBreadcrumbs()` parses path into clickable segments
- **Directory traversal** - Single click selects, double-click navigates into folder
- **New folder creation** - Lines 78-101: `handleCreateFolder()` calls `api.createDirectory()`

**Key Callbacks:**
- `onSelect(path: string)` - Called when user clicks "Select This Folder" button (line 105)
- `onCancel()` - Called when user cancels selection
- Path is the **directory path itself**, NOT appended with project name (NewProjectModal does that)

**UI Features:**
- Displays only directories (filters `entry.is_directory` on line 221)
- Shows selected path in footer with monospace font (line 306)
- "New Folder" button to create folders on-the-fly
- Breadcrumb navigation with drive indicators

---

### 3. useProjects.ts Hook - Project Creation API Hook

**File:** `C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\autocoder-master\ui\src\hooks\useProjects.ts`

**useCreateProject Hook (lines 28-38):**
```typescript
export function useCreateProject() {
  return useMutation({
    mutationFn: ({ name, path, specMethod }) =>
      api.createProject(name, path, specMethod),
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ['projects'] })
    },
  })
}
```

**Behavior:**
- Returns mutation object with `.mutateAsync()` for async calls
- Parameters: `name`, `path`, `specMethod: 'claude' | 'manual'`
- On success, invalidates the `['projects']` query cache (triggering refresh)
- Called from NewProjectModal (lines 92-96, 108-112)

---

### 4. api.ts - REST API Client

**File:** `C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\autocoder-master\ui\src\lib\api.ts`

**Projects Endpoints:**

1. **`createProject(name, path, specMethod)`** (lines 48-57):
   ```
   POST /api/projects
   Body: { name, path, spec_method: specMethod }
   Returns: ProjectSummary { name, path, has_spec, stats }
   ```

2. **`listProjects()`** (lines 44-46):
   ```
   GET /api/projects
   Returns: ProjectSummary[]
   ```

3. **`getProject(name)`** (lines 59-61):
   ```
   GET /api/projects/{name}
   Returns: ProjectDetail extends ProjectSummary
   ```

4. **`deleteProject(name)`** (lines 63-67):
   ```
   DELETE /api/projects/{name}
   ```

**Filesystem Endpoints:**

1. **`listDirectory(path?)`** (lines 182-185):
   ```
   GET /api/filesystem/list?path={path}
   Returns: DirectoryListResponse
   ```

2. **`createDirectory(fullPath)`** (lines 187-225):
   ```
   POST /api/filesystem/create-directory
   Body: { parent_path, name }  // NOT { path }
   Returns: { success: boolean, path: string }
   Note: Function parses fullPath into parent_path + name
   ```

3. **`validatePath(path)`** (lines 227-232):
   ```
   POST /api/filesystem/validate
   Body: { path }
   Returns: PathValidationResponse { valid, exists, is_directory, can_write, message }
   ```

**Agent Control Endpoints:**

1. **`startAgent(projectName, yoloMode?)`** (lines 122-130):
   ```
   POST /api/projects/{projectName}/agent/start
   Body: { yolo_mode: yoloMode }
   Returns: AgentActionResponse
   ```

2. **`stopAgent(projectName)`**, **`pauseAgent(projectName)`**, **`resumeAgent(projectName)`** - Similar pattern

---

## Current Project Creation Data Flow

```
User enters name
    ↓
Name validation (regex)
    ↓
User selects folder via FolderBrowser
    ↓ [selectedPath from FolderBrowser.onSelect]
Path concatenation: fullPath = `${selectedPath}/${projectName}`
    ↓
User selects method (Claude or Manual)
    ↓ [POST /api/projects with: { name, path, spec_method }]
Project created in backend
    ↓
If Manual: Show completion → Navigate to project
If Claude: Show SpecCreationChat → Collect spec → startAgent() → Navigate
```

---

## Design for "Import" Mode

To add an import mode that selects an existing folder, here's what would need to change:

### 1. NewProjectModal.tsx Modifications

**Add new step:**
- `type Step = 'name' | 'folder' | 'method' | 'chat' | 'complete' | 'import'`

**Add import selection button in method step:**
- New button: "Import Existing Project"
- Routes to new 'import' step before 'folder'

**Import step logic:**
- Show two options: "Create New Folder" vs "Use Existing Folder"
- If existing: FolderBrowser with validation to check folder isn't empty (optional)
- If new: Existing flow (name → folder selection)

### 2. FolderBrowser.tsx Enhancement

**Add import mode prop:**
```typescript
interface FolderBrowserProps {
  onSelect: (path: string) => void
  onCancel: () => void
  initialPath?: string
  importMode?: boolean  // NEW: If true, validates non-empty directory
}
```

**Validation in import mode:**
- Show warning if folder contains files (not empty)
- Require explicit confirmation: "Import this project with existing files?"

### 3. API Changes

**New endpoint option:**
- Could extend existing `/api/projects` to support `import_existing: boolean` parameter
- Backend would validate:
  - Folder exists
  - Contains valid project structure (if enforced)
  - Not already registered in project registry

**Or separate endpoint:**
```
POST /api/projects/import
Body: { name, path, is_existing: true }
```

### 4. State Management in NewProjectModal

**Add import flag:**
```typescript
const [isImportMode, setIsImportMode] = useState(false)
```

**Modified flow:**
```
Create/Import selection
  ├─ Create New → name → folder (NEW) → method → chat/complete
  └─ Import Existing → folder (VALIDATE) → method → chat/complete
```

---

## Key Design Insights

1. **Path Handling:** The modal appends project name to selected folder path (crucial detail for import mode - wouldn't do this for existing folders)

2. **API Contract:** Backend expects full path in `path` parameter, not separate parent/name like filesystem operations

3. **FolderBrowser Reusability:** Component is generic - could work for import by adding validation logic

4. **State Isolation:** Import flag would be separate from specMethod - they're orthogonal concerns (how you get the folder vs what you do with it)

5. **Backward Compatibility:** Creating new project in empty folder should remain the default/recommended path

This structure keeps the existing "new project" flow intact while adding parallel "import" logic that branches early.

Prompt:
Explore the autocoder+ frontend to understand the project creation flow. Focus on:

1. NewProjectModal.tsx - how it manages steps, state, and creates projects
2. FolderBrowser.tsx - how folder selection works, what API it uses
3. useProjects.ts hook - how projects are created via API
4. The API client (api.ts) - what endpoints exist for projects

I need to understand:
- How the current "new project" wizard works step-by-step
- How FolderBrowser handles path selection and what callbacks it uses
- What data is sent when creating a project
- How we could add an "import" mode that selects an existing folder instead of creating a new one

Base path: C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\autocoder-master\ui\src


Perfect! Now I have a comprehensive understanding. Let me create a detailed report of my findings.

## Autocoder+ Backend Architecture Exploration

I've thoroughly analyzed the backend codebase. Here's a comprehensive breakdown of the project creation and WebSocket implementation:

### 1. PROJECT CREATION FLOW

**Database Model** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\models\project.py):
- Project table has: `id`, `name` (unique), `path`, `created_at`, `updated_at`, `spec_version`
- Cascading relationships to Features, Permissions, Infrastructure, and SpecHistory

**Create Project Endpoint** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\routers\projects.py):
```
POST /api/projects
Body: {
  "name": str,
  "path": str
}
```
- Validates path using `validate_project_path()` to prevent path traversal attacks
- Checks for duplicate project names (409 CONFLICT if exists)
- Creates new Project record with initial `spec_version=1`
- Returns ProjectResponse with id, name, path, timestamps, and spec_version

**Path Security** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\path_security.py):
- Blocks dangerous paths (Windows: C:\Windows, C:\Program Files; Unix: /etc, /bin, /root, etc.)
- Prevents path traversal patterns: `../`, `..\`, URL-encoded variants
- Normalizes and validates paths before acceptance

---

### 2. SPEC CREATION & WEBSOCKET

**Spec Management** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\routers\spec.py):
- Tracks spec versions in `SpecHistory` table (project_id, version, content, change_summary, created_at)
- **Update spec endpoint**: `PUT /api/projects/{name}/spec` - increments version, stores new content
- **Get current spec**: `GET /api/projects/{name}/spec` - returns latest version
- **Spec history**: `GET /api/projects/{name}/spec/history` - returns all versions
- **Rollback**: `POST /api/projects/{name}/spec/rollback/{version}` - creates new version copying old content
- **Change analysis**: `POST /api/projects/{name}/spec/analyze-changes` - analyzes which features might be affected by spec changes

**WebSocket Connection** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\routers\websocket.py):

```
Connection: WS /ws/projects/{project_name}
```

**ConnectionManager** handles:
- Per-project connection sets (multiple clients per project)
- Heartbeat loop (sends ping every 30 seconds)
- Auto-cleanup of disconnected clients
- Broadcasting to all connected clients for a project

**Message Types**:
- `heartbeat` - periodic keepalive
- `agent_log` - log output with type (info/error/tool/permission)
- `agent_status` - agent status changes
- `feature_update` - feature modifications
- `permission_request` - new permission requests from agents

**Initial Connection Flow**:
1. Client connects to `/ws/projects/{project_name}`
2. Project existence verified in database
3. Connection accepted and added to manager
4. Client receives `{"type": "connected", "project": name, ...}`
5. Heartbeat starts
6. Client can send `ping` messages (gets `pong` response)

---

### 3. ROUTE REGISTRATION

**Main App** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\main.py):

```python
from .routers import (
    projects_router, websocket_router, agents_router,
    features_router, permissions_router, spec_router,
    infrastructure_router, git_router
)

app.include_router(projects_router)
app.include_router(websocket_router)
# ... etc
```

**Router Organization** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\routers\__init__.py):
- Each router is defined in its own module
- Centrally exported for clean imports
- Prefixes organize endpoints: `/api/projects`, `/ws/projects`

---

### 4. DATA PASSED DURING SPEC CREATION

The system doesn't have a dedicated "spec creation WebSocket" - instead it uses:

**REST Endpoints for spec updates**:
- PUT /api/projects/{name}/spec - client sends new content
- Triggers creation of new SpecHistory record
- WebSocket broadcasting happens for any observers

**Context Available During Spec Updates**:
1. **Project Context**: project_id, name, path
2. **Spec Content**: Full spec text (unlimited size via Text field)
3. **Change Metadata**: change_summary, version number
4. **Feature Relationships**: Can access all features for change analysis

**What Agents See**:
- Current spec version via `GET /api/projects/{name}/spec`
- Full spec history via `GET /api/projects/{name}/spec/history`
- Features affected by changes via `POST /api/projects/{name}/spec/analyze-changes`

---

### 5. IMPORT PROJECT ENDPOINT DESIGN

To add an "import project" feature that registers an existing folder, here's what would be needed:

**Key Considerations**:

1. **Path Validation** - Use existing `validate_project_path()` function
2. **Project Uniqueness** - Check name doesn't exist (duplicate prevention)
3. **Folder Verification** - Check if path exists on filesystem
4. **Associated Data**:
   - Scan for existing features and register them
   - Detect existing permissions/infrastructure if tracked elsewhere
   - Initialize spec_version (could scan for README/spec file)
   - Optionally create initial SpecHistory entry

**Endpoint Structure**:
```
POST /api/projects/import
Body: {
  "name": str,
  "path": str,
  "scan_features": bool = True  # Auto-scan for existing features
}
Response: ProjectResponse (same as create)
```

**Database Flow**:
1. Validate path (use existing validate_project_path)
2. Check Project.name doesn't exist
3. Optionally validate path exists with os.path.exists()
4. Create new Project record
5. Optional: Create initial SpecHistory entry
6. Optional: Scan directory for feature definitions and create Feature records

---

### 6. AGENT CONTEXT & STATE

**Agent Status Tracking** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\routers\agents.py):
- In-memory state: `_agent_states[project_name][agent_id]` = status (stopped/running/paused/stalled/error)
- Tracks: started_at, paused_at, error message, crashed_at
- Dual agent system: Agent A and Agent B per project

**Features Associated with Projects** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\models\feature.py):
- Each project has multiple features
- Features track: name, description, category, priority, steps
- Status fields: passes, in_progress, stalled, assigned_agent
- Dependencies: depends_on (list of feature IDs), files_modified (list of paths)

---

2. backend/app/routers/websocket.py - spec creation WebSocket handler
3. backend/app/main.py - how routes are registered
4. Any filesystem/folder browsing endpoints

I need to understand:
- How projects are created in the database
- How the spec creation WebSocket session works
- What context/data is passed to Claude during spec creation
- How we could add an "import project" endpoint that registers an existing folder

Base path: C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend


I now have a comprehensive understanding of both the frontend and backend. Let me also check the spec creation WebSocket in the main autocoder-master project (not backend) since the frontend connects to `/api/spec/ws/{project_name}` according to useSpecChat.ts, and I saw a websocket.py in the backend but it might be different. Let me check if there's a spec WebSocket router.

Actually, looking at the frontend hook, it connects to:
```javascript
const wsUrl = `${protocol}//${host}/api/spec/ws/${encodeURIComponent(projectName)}`
```

But the backend routers I explored had `websocket.py` with `/ws/projects/{project_name}`. There might be two different WebSocket systems - one in the main autocoder-master server and one in the backend. Let me check the main autocoder-master server directory.

Also, I need to understand how the spec creation chat actually works with Claude. The frontend useSpecChat.ts shows it connects and sends messages, but I need to see the backend handler that actually talks to Claude.

Looking at the directory structure:
- `autocoder-master/server/` - has routers including spec_creation.py
- `backend/app/routers/` - has websocket.py, spec.py, etc.

It seems like there are two different servers. Let me explore this more to understand which one handles the spec creation WebSocket.

Actually, let me ask the user a clarifying question since there seem to be two server implementations.


Excellent findings from both agents. I see there are two server implementations:
1. `autocoder-master/server/` - Original server with spec creation WebSocket
2. `backend/app/` - Newer backend with enhanced features

Let me check which server handles the spec creation chat and understand how context is passed to Claude:
