# AI Blog Writer: Stage 3 Content Generation - Implementation Plan

## 📋 **Overview**

This document outlines the complete implementation plan for Stage 3: Content Generation of the AI Blog Writer. The plan addresses content continuity, narrative flow, factual accuracy, and comprehensive audit systems while leveraging Gemini API's URL context capabilities.

## 🎯 **Core Challenges & Solutions**

### **Challenge 1: Content Continuity & Narrative Flow**
- **Problem**: Each section generated independently loses narrative thread
- **Solution**: Build narrative flow engine with context awareness
- **Impact**: Seamless reading experience, improved user engagement

### **Challenge 2: Section-by-Section Audit Requirements**
- **Problem**: Need comprehensive tracking for user working on individual sections
- **Solution**: Multi-layered audit system with real-time validation
- **Impact**: Quality control, consistency maintenance, user confidence

### **Challenge 3: Factual Accuracy & Source Integration**
- **Problem**: Current system lacks deep source integration for factual content
- **Solution**: Leverage Gemini URL context tool for enhanced factual generation
- **Impact**: Higher credibility, accurate citations, competitive content quality

## 🏗️ **Implementation Architecture**

### **1. Enhanced Content Generation Pipeline**

```
Section Request → Context Analysis → Source URL Extraction → URL Context Integration → 
Progressive Content Building → Quality Gates → Continuity Validation → Final Output
```

### **2. Core Components**

#### **A. Narrative Flow Engine**
- **Context Memory System**: Tracks narrative threads, key concepts, tone profile
- **Transition Generator**: Creates smooth transitions between sections
- **Flow Analyzer**: Assesses narrative coherence and continuity
- **Tone Consistency Manager**: Maintains consistent voice across sections

#### **B. Enhanced Content Generator**
- **URL Context Integration**: Uses Gemini URL context tool for factual content
- **Source URL Manager**: Extracts and manages relevant source URLs
- **Progressive Builder**: Builds content with quality gates
- **Citation System**: Integrates proper source citations
 - **Context Cache & Memoization (New)**: Reuse fetched URL content and prior section summaries to cut latency/cost without changing outputs

#### **C. Comprehensive Audit System**
- **Multi-Dimensional Assessment**: Continuity, factual, flow, SEO, tone audits
- **Quality Gates**: Structure, accuracy, continuity, SEO validation
- **Real-Time Monitoring**: Live quality assessment during generation
- **Improvement Recommendations**: Specific suggestions for content enhancement
 
#### **D. Lightweight UX Enhancements (No timeline impact)**
- **Streaming Output**: Stream tokens to the editor for perceived speed (supported by CopilotKit)
- **Micro‑Approval for Transitions**: 1–2 sentence transition preview with Accept/Regenerate
- **Speed Modes**: Draft (fast, flash-lite) vs Polished (flash/pro) toggle per section

## 🤖 **AI Prompt Engineering Strategy**

### **1. Context-Aware Content Generation**

**Base Prompt Template:**
```
You are an expert content writer creating section "{section_heading}" for a comprehensive blog post.

CONTEXT:
- Previous sections: {previous_sections_summary}
- Narrative thread: {narrative_threads}
- Key concepts: {key_concepts}
- Tone profile: {tone_profile}

RESEARCH SOURCES:
{source_urls_with_context}

REQUIREMENTS:
- Maintain narrative flow from previous sections
- Use factual information from provided sources
- Target word count: {target_words}
- Keywords to optimize: {keywords}
- Include proper citations and references
- Ensure smooth transition from previous content
```

### **2. Continuity-Focused Prompts**

**Transition Generation:**
```
Create a smooth transition from "{previous_section_heading}" to "{current_section_heading}".

Previous section ending: {last_200_chars}
Current section focus: {key_points}

Generate 1-2 sentences that:
- Maintain narrative flow
- Introduce new topic naturally
- Keep reader engaged
- Reference previous concepts when relevant
```

### **3. Quality Audit Prompts**

**Continuity Assessment:**
```
Analyze the narrative continuity between these sections:

Previous sections: {previous_sections}
Current section: {current_section}

Rate on scale 1-10:
- Flow quality (smooth transitions)
- Concept consistency (key themes maintained)
- Tone consistency (voice alignment)
- Logical progression (argument development)

Provide specific recommendations for improvement.
```

### **4. Guardrails & Structure (New)**

**Style & Governance Pack:**
```
Adopt the following immutable constraints for this project:
- Voice & Tone: {persona_style_guide}
- Formatting: markdown; H2/H3 only; bullets for lists
- Banned patterns: hype adjectives, vague claims, vendor puffery
- Citations: every numeric claim must reference a source URL
```

**Structured Output Schema (per section):**
```
{
  "heading": string,
  "transition": string,          // 1–2 sentences
  "markdown": string,            // body content
  "citations": [ { "text": string, "url": string } ],
  "keywords_used": string[],
  "summary_100t": string        // <= 100 tokens continuity summary
}
```

These guardrails reduce revision cycles while keeping implementation light.
