# **AI-Powered Task Context Generation - Implementation Summary**
2+
3+
## **🎉 Implementation Complete**
4+
5+
Successfully implemented comprehensive AI-powered task context generation functionality based on the PRD requirements, with **traceability-based context as default** and **AI enhancement as optional**.
6+
7+
---
8+
9+
## **📋 What Was Implemented**
10+
11+
### **1. Core Architecture**
12+
13+
#### **TaskContextGenerationService** (`src/services/TaskContextGenerationService.ts`)
14+
- **Hybrid approach**: Traceability-based context (default) + AI enhancement (optional)
15+
- **Graceful degradation**: Works without AI keys, falls back to traceability context
16+
- **Configurable context levels**: minimal, standard, full
17+
- **Performance optimized**: Fast default with optional AI enhancement
18+
19+
#### **Enhanced Task Interfaces** (`src/domain/ai-types.ts`)
20+
- **TaskExecutionContext**: Comprehensive business, technical, and feature context
21+
- **EnhancedAcceptanceCriteria**: Detailed verification methods and priorities
22+
- **ImplementationGuidance**: Step-by-step implementation recommendations
23+
- **ContextualReferences**: Links to PRD sections, features, and technical specs
24+
- **EnhancedAITask**: Extended task interface with rich contextual information
25+
26+
#### **AI Prompts** (`src/services/ai/prompts/ContextGenerationPrompts.ts`)
27+
- **Business Context Prompts**: Extract business objectives, user impact, success metrics
28+
- **Technical Context Prompts**: Analyze constraints, architecture decisions, integrations
29+
- **Implementation Guidance Prompts**: Generate step-by-step recommendations
30+
- **Contextual References Prompts**: Create relevant documentation links
31+
- **Enhanced Acceptance Criteria Prompts**: Generate detailed, testable criteria
32+
33+
### **2. Configuration System**
34+
35+
#### **Environment Defaults (Traceability-Based)**
36+
```bash
37+
ENHANCED_TASK_GENERATION=true # Enhanced generation enabled
38+
ENHANCED_CONTEXT_LEVEL=standard # Standard context level
39+
INCLUDE_BUSINESS_CONTEXT=false # AI business context OFF by default
40+
INCLUDE_TECHNICAL_CONTEXT=false # AI technical context OFF by default
41+
INCLUDE_IMPLEMENTATION_GUIDANCE=false # AI implementation guidance OFF by default
42+
```
43+
44+
#### **Tool-Level Configuration**
45+
- **parse_prd tool** supports all context configuration options
46+
- **Default behavior**: Enhanced generation with traceability-based context
47+
- **Optional AI enhancement**: Can be enabled per-tool call
48+
49+
### **3. Context Generation Capabilities**
50+
51+
#### **Default: Traceability-Based Context** ✅
52+
- **Business Context**: Extracted from PRD objectives and traceability links
53+
- **Feature Context**: Parent feature information from traceability matrix
54+
- **Technical Context**: Basic constraints and architectural decisions
55+
- **Success Metrics**: Derived from acceptance criteria and requirements
56+
- **Always Available**: Works without AI keys
57+
58+
#### **Enhanced: AI-Powered Context** ✅ (when AI available)
59+
- **Business Context**: AI-extracted business objectives, user impact, success metrics
60+
- **Technical Context**: AI-analyzed technical constraints, architecture decisions, integration points
61+
- **Implementation Guidance**: AI-generated step-by-step implementation recommendations
62+
- **Contextual References**: AI-extracted PRD sections, code examples, technical specs
