## [0.7.7] - 2025-01-08

### 🚀 **CRITICAL FIX: NPM Package Path Resolution & Template Files**

This release fixes critical issues with the npm package initialization and ensures all template files are properly included in the published package.

### 🚨 **Critical Issues Resolved**

#### **NPM Package Template Files Missing**
- **Fixed:** Template files not included in npm package due to missing `assets/**` in files array
- **Root Cause:** `package.json` files array didn't include `assets/` directory containing templates
- **Solution:** Added `assets/**`, `config/**`, and `.cursor/**` to package files

#### **Path Resolution Issues in CLI**
- **Fixed:** CLI commands failing with wrong project root detection

#### **Simplified NPX Configuration**
- **Adopted:** Simple and efficient npx approach inspired by taskmaster-ai
- **Command:** `npx -y --package=task-engine-ai-core task-master-mcp`
- **Benefits:** Automatic package management, no path resolution issues, cross-platform compatibility

### 🔧 **Working Configuration (No Hardcoded Paths)**

#### **Cursor IDE (`.cursor/mcp.json`)**
```json
{
  "mcpServers": {
    "task-engine-ai-core": {
      "command": "npx",
      "args": ["-y", "--package=task-engine-ai-core", "task-master-mcp"],
      "env": {
        "TASK_ENGINE_VERSION": "0.3.6",
        "TASK_ENGINE_ENVIRONMENT": "development",

        "DEFAULT_SUBTASKS": "5",
        "DEFAULT_PRIORITY": "medium"
      }
    }
  }
}
```

#### **VS Code (`.vscode/mcp.json`)**
```json
{
  "servers": {
    "task-engine-ai-core": {
      "command": "npx",
      "args": ["-y", "--package=task-engine-ai-core", "task-master-mcp"],

- **After:** Project root detected dynamically at runtime
- **Benefit:** Works in any project directory without configuration changes

### ⚡ **Simplified Setup Process**

#### **Universal Configuration**
```bash
# Same configuration works for ANY project
{
  "command": "npx",
  "args": ["-y", "--package=task-engine-ai-core", "task-master-mcp"]
}
```

#### **Project-Agnostic Setup**
- **One configuration** works for all projects
- **No path customization** required per project
