## Phase 1: Path Normalization & Error Handling

**Priority:** P0  
**Dependencies:** None  
**Estimated Effort:** 2-3 days

### Goals

Ensure consistent path handling across Windows, macOS, and Linux, with clear error messages.

### Tasks

#### 1.1 Path Normalization Utility

**File:** `path-utils.ts` (new)

- [x] Create utility module for path operations
- [x] Implement `normalizePath(path: string): string`
  - Strip leading/trailing slashes
  - Convert backslashes to forward slashes
  - Handle Windows drive letters
  - Normalize case on Windows (case-insensitive)
  - Preserve case on macOS/Linux (case-sensitive)
- [x] Implement `isValidVaultPath(path: string): boolean`
- [x] Implement `resolveVaultPath(app: App, path: string): TFile | TFolder | null`
- [x] Add unit tests for path normalization

#### 1.2 Update All Tool Implementations

- [x] Replace direct `getAbstractFileByPath` calls with `PathUtils.resolveFile/Folder`
- [x] Update `readNote`, `createNote`, `updateNote`, `deleteNote`, `listNotes`
- [x] Add path normalization to all endpoints

#### 1.3 Enhanced Error Messages

**File:** `error-messages.ts` (new)

- [x] Create error message templates with helpful guidance
- [x] Include suggested next actions
- [x] Add links to documentation examples
- [x] Implement `fileNotFound()`, `folderNotFound()`, `invalidPath()` helpers

**Example Error Format:**
```
File not found: "path/to/file.md"

Troubleshooting tips:
• Omit leading/trailing slashes
• Check vault-relative path casing
• Try stat("path") to verify
• Use list_notes() to see available files
```

#### 1.4 Testing

- [x] Test with Windows paths (backslashes, drive letters)
- [x] Test with macOS paths (case-sensitive)
- [x] Test with Linux paths
- [x] Test trailing slash handling
- [x] Test error message clarity

**Note:** Test files have been created in `tests/` directory. To run tests, Jest needs to be set up (see `tests/README.md`).

#### 1.5 Enhanced Parent Folder Detection

**Priority:** P0  
**Status:** ✅ Complete  
**Estimated Effort:** 0.5 days

**Goal:** Improve parent folder validation in `createNote()` with explicit detection before write operations.

**Implementation Summary:**
- ✅ Explicit parent folder detection before write operations
- ✅ Enhanced error message with `createParents` suggestion
- ✅ `createParents` parameter with recursive folder creation
- ✅ Comprehensive test coverage
- ✅ Updated tool schema and documentation

**Tasks:**

- [x] Add explicit parent folder detection in `createNote()`
  - Compute parent path using `PathUtils.getParentPath(path)` before write
  - Check if parent exists using `PathUtils.pathExists(app, parentPath)`
  - Check if parent is actually a folder (not a file)
  - Return clear error before attempting file creation

- [x] Enhance `ErrorMessages.parentFolderNotFound()`
  - Ensure consistent error message template
  - Include parent path in error message
  - Provide actionable troubleshooting steps
  - Suggest using `createParents: true` parameter

- [x] Add `createParents` parameter
  - Add optional `createParents?: boolean` parameter to `create_note` tool
  - Default to `false` (no auto-creation)
  - If `true`, recursively create parent folders before file creation
  - Document behavior clearly in tool description
  - Add tests for both modes

- [x] Update tool schema
  - Add `createParents` parameter to `create_note` inputSchema
  - Document default behavior (no auto-creation)
  - Update tool description to mention parent folder requirement
  - Pass parameter through callTool method

- [x] Testing
  - Test parent folder detection with missing parent
  - Test parent folder detection when parent is a file
  - Test with nested missing parents (a/b/c where b doesn't exist)
  - Test `createParents: true` creates all missing parents
  - Test `createParents: false` returns error for missing parents
  - Test error message clarity and consistency

**Implementation Notes:**

```typescript
// Pseudo-code for enhanced createNote()
async createNote(path: string, content: string, createParents = false) {
  // Validate path
  if (!PathUtils.isValidVaultPath(path)) {
    return ErrorMessages.invalidPath(path);
  }

  // Normalize path
  const normalizedPath = PathUtils.normalizePath(path);

  // Check if file already exists
  if (PathUtils.fileExists(this.app, normalizedPath)) {
    return ErrorMessages.pathAlreadyExists(normalizedPath, 'file');
  }

  // Explicit parent folder detection
  const parentPath = PathUtils.getParentPath(normalizedPath);
  if (parentPath) {
    // Check if parent exists
    if (!PathUtils.pathExists(this.app, parentPath)) {
      if (createParents) {
        // Auto-create parent folders
        await this.createParentFolders(parentPath);
      } else {
        return ErrorMessages.parentFolderNotFound(normalizedPath, parentPath);
      }
    }
    
    // Check if parent is actually a folder (not a file)
    if (PathUtils.fileExists(this.app, parentPath)) {
      return ErrorMessages.notAFolder(parentPath);
    }
  }

  // Proceed with file creation
  try {
    const file = await this.app.vault.create(normalizedPath, content);
    return { success: true, path: file.path };
  } catch (error) {
    return ErrorMessages.operationFailed('create note', normalizedPath, error.message);
  }
}
```

**Error Message Template:**

```
Parent folder does not exist: "mcp-plugin-test/missing-parent"

Cannot create "mcp-plugin-test/missing-parent/file.md" because its parent folder is missing.

Troubleshooting tips:
• Create the parent folder first using Obsidian
• Verify the folder path with list_notes("mcp-plugin-test")
• Check that the parent folder path is correct (vault-relative, case-sensitive on macOS/Linux)
• Note: Automatic parent folder creation is not currently enabled
• Consider using createParents: true parameter to auto-create folders
```

**Benefits:**

- ✅ Explicit detection before write operation (fail fast)
- ✅ Clear error message with exact missing parent path
- ✅ Consistent error messaging across all tools
- ✅ Optional auto-creation for convenience
- ✅ Better user experience with actionable guidance

      },
      createParents: { type: "boolean", default: true }
    },
    required: ["path", "content"]
  }
}
```

  success: boolean,
  oldPath: string,
  newPath: string,
  linksUpdated: number,  // Count of files with updated links
  affectedFiles: string[]  // Paths of files that had links updated
}
```

**Implementation Notes:**

```json
{
  "enabled": false,
  "verbosity": "off",
  "showParameters": false,
  "duration": 3000,
  "logToConsole": false
}
```

### Implementation Notes

**Obsidian Notice API:**
```typescript
// Use Obsidian's built-in Notice class
import { Notice } from 'obsidian';

new Notice('Message', 3000);  // 3 second duration
```

**Performance Considerations:**
- Notifications should not block tool execution
