 PraisonAI provides a complete knowledge stack for building RAG applications with multiple vector stores, retrieval strategies, rerankers, and query modes.
 
+### RAG Quickstart (Agent-first)
+
+```python
+from praisonaiagents import Agent
+from praisonaiagents.rag.models import RetrievalStrategy
+
+# Agent with RAG - simplest approach
+agent = Agent(
+    name="Research Assistant",
+    knowledge=["docs/manual.pdf", "data/faq.txt"],
+    knowledge_config={"vector_store": {"provider": "chroma"}},
+    rag_config={
+        "include_citations": True,
+        "retrieval_strategy": RetrievalStrategy.HYBRID,  # Dense + BM25
+        "rerank": True,
+    }
+)
+
+# Query with citations
+result = agent.rag_query("How do I authenticate?")
+print(result.answer)
+for citation in result.citations:
+    print(f"  [{citation.id}] {citation.source}")
+```
+
+### RAG CLI Commands
+
+| Command | Description |

-### Knowledge SDK Usage
+### Knowledge vs RAG vs AutoRagAgent
+
+- **Knowledge** is the indexing and retrieval substrate - use for indexing and raw search
+- **RAG** orchestrates on top - use for question answering with LLM-generated responses and citations
+- **AutoRagAgent** wraps an Agent with automatic retrieval decision - use when you want the agent to decide when to retrieve
+- All share the same underlying index
+
+### AutoRagAgent (Automatic RAG)
+
+AutoRagAgent automatically decides when to retrieve context from knowledge bases vs direct chat, based on query heuristics.
 
 ```python
-from praisonaiagents import Agent, Knowledge
+from praisonaiagents import Agent, AutoRagAgent
 
-# Simple usage with Agent
+# Create agent with knowledge
 agent = Agent(
     name="Research Assistant",
-    knowledge=["docs/manual.pdf", "data/faq.txt"],
-    knowledge_config={
-        "vector_store": {"provider": "chroma"}
-    }
+    knowledge=["docs/manual.pdf"],
+    user_id="user123",  # Required for RAG retrieval
 )
-response = agent.chat("How do I authenticate?")
 
-# Direct Knowledge usage
-knowledge = Knowledge()
-knowledge.add("document.pdf")
-results = knowledge.search("authentication", limit=5)
+# Wrap with AutoRagAgent
+auto_rag = AutoRagAgent(
+    agent=agent,
+    retrieval_policy="auto",  # auto, always, never
+    top_k=5,
+    hybrid=True,
+    rerank=True,
+)
+
+# Auto-decides: retrieves for questions, skips for greetings
+result = auto_rag.chat("What are the key findings?")  # Retrieves
+result = auto_rag.chat("Hello!")  # Skips retrieval
+
+# Force retrieval or skip per-call
+result = auto_rag.chat("Hi", force_retrieval=True)
+result = auto_rag.chat("Summary?", skip_retrieval=True)
+```
+
+**CLI Usage:**
+```bash
+# Enable auto-rag with default policy (auto)
+praisonai --auto-rag "What are the key findings?"
+
+# Always retrieve
+praisonai --auto-rag --rag-policy always "Tell me about X"
+
+# With hybrid retrieval and reranking
+praisonai --auto-rag --rag-hybrid --rag-rerank "Summarize the document"
+```
+
+### Configuration Precedence
+
+Settings are applied in this order (highest priority first):
+1. **CLI flags** - `--hybrid`, `--rerank`, `--top-k`
+2. **Environment variables** - `PRAISONAI_HYBRID=true`
+3. **Config file** - YAML configuration (`--config`)
+4. **Defaults**
+
+```bash
+# Environment variables
+export PRAISONAI_HYBRID=true
+export PRAISONAI_RERANK=true
+export PRAISONAI_TOP_K=10
+```
+
+### Lightweight Installs
+
+```bash
+# Base install (minimal, fast imports)
+pip install praisonaiagents
+
+# With RAG API server support
+pip install "praisonai[rag-api]"
+```
+
+### Live Tests (Real API Keys)
+
+Run integration tests with real API keys:
+
+```bash
+# Enable live tests
+export PRAISONAI_LIVE_TESTS=1
+export OPENAI_API_KEY="your-key"
+
+# Run live tests
+pytest -m live tests/integration/
 ```

+
+## Chapter 1: Getting Started
+
+CloudManager Pro is an enterprise cloud management platform that helps organizations
+monitor, optimize, and secure their multi-cloud infrastructure. This guide covers
+installation, configuration, and daily operations.
+
+### 1.1 System Requirements
+
+Before installing CloudManager Pro, ensure your system meets these requirements:
+- Operating System: Ubuntu 20.04+, RHEL 8+, or Windows Server 2019+
+- Memory: Minimum 16GB RAM, recommended 32GB for production
+- Storage: 100GB SSD for application, additional storage for logs
+- Network: Outbound HTTPS access to cloud provider APIs
+
+### 1.2 Installation Steps
+
+1. Download the installer from the customer portal
+2. Run the installation script with root privileges
+3. Configure the database connection
+4. Set up the initial admin account
+5. Verify the installation with the health check command
+
+## Chapter 2: Dashboard Overview
+
+The main dashboard provides a unified view of your cloud resources across all
+connected providers. Key metrics displayed include:
+
+### 2.1 Resource Metrics
+
+- Total compute instances across all clouds
+- Storage utilization and growth trends
+- Network bandwidth consumption
+- Cost breakdown by provider and project
+
+### 2.2 Alert Summary
+
+The alert panel shows active incidents categorized by severity:
+- Critical: Immediate action required (service outages)
+- Warning: Attention needed within 24 hours
+- Info: Informational notifications
+
+## Chapter 3: Cost Optimization
+
+CloudManager Pro includes powerful cost optimization features that can reduce
+your cloud spending by 20-40%.
+
+### 3.1 Right-sizing Recommendations
+
+The platform analyzes resource utilization patterns and suggests optimal
+instance sizes. Recommendations are based on:
+- CPU utilization over 14-day periods
+- Memory usage patterns
+- Network I/O requirements
+
+### 3.2 Reserved Instance Planning
+
+Use the RI Planner to identify opportunities for reserved instance purchases.
+The tool calculates potential savings based on your usage patterns and
+commitment preferences (1-year vs 3-year terms).
+
+## Chapter 4: Security Features
+
+### 4.1 Compliance Monitoring
+
+CloudManager Pro continuously monitors your infrastructure against common
+compliance frameworks including SOC 2, HIPAA, and PCI-DSS. Non-compliant
+resources are flagged with remediation guidance.

+    
+    2. **Instruct Agent to Cite**
+       - Be explicit in instructions about citation format
+       - Provide examples of expected citation style
+       - Require citations for factual claims
+    
+    3. **Use Consistent Citation Format**
+       - Inline: [1], [2] with reference list
+       - Parenthetical: (Source, Section)
+       - Footnote style: ¹, ² with notes
+    
+    4. **Enable Verification**
+       - Include document IDs for programmatic lookup
+       - Store enough metadata to locate original
+       - Consider including page numbers or paragraphs
+    
+    5. **Handle Missing Sources**
+       - Instruct agent to acknowledge when info isn't in sources
+       - Distinguish between sourced and general knowledge
+       - Use phrases like "Based on the provided documents..."
+    
+    6. **Citation Granularity**
+       - Document level: Good for general attribution
+       - Section level: Better for verification
+       - Quote level: Best for accuracy-critical applications
+    
+    Example Agent Instructions:
+    ```python
+    instructions = '''
+    Answer questions using the provided documents.
+    
+    Rules:
+    - Cite sources for all factual claims
+    - Use format: [Source: Document Name, Section]
+    - If information isn't in the documents, say so
+    - Never make claims without citation

+    
+    1. **Query-Time Augmentation**
+       - Fetch external data when query arrives
+       - Inject into prompt as additional context
+       - Best for: Real-time data needs
+    
+    2. **Scheduled Refresh**
+       - Periodically update knowledge base from external sources
+       - Index external data for faster retrieval
+       - Best for: Semi-static external data
+    
+    3. **Tool-Based Retrieval**
+       - Give agent tools to fetch external data

+    📚 Best Practices for Multi-Document RAG:
+    
+    1. **Document Metadata**
+       - Include source, date, author in each document
+       - Enables filtering and citation
+    
+    2. **Consistent Chunking**
+       - Use similar chunk sizes across documents
+       - Maintains balanced retrieval
+    
+    3. **Source Diversity**
+       - Retrieve from multiple sources when possible
+       - Reduces single-source bias
+    
+    4. **Conflict Resolution**
+       - Instruct agent how to handle contradictions
+       - Prefer newer sources or authoritative ones
+    
+    5. **Citation Requirements**
+       - Ask agent to cite sources in responses
+       - Enables verification and trust
+    
+    Example configuration:
+    ```python
+    documents = [

+    🎯 Constrained Generation Techniques:
+    
+    1. **Schema Enforcement**
+       - Provide JSON schema in instructions
+       - Agent outputs valid JSON matching schema
+       ```python
+       instructions = f"Respond with JSON matching: {schema}"
+       ```
+    
+    2. **Format Templates**
+       - Give explicit output templates
+       - Agent fills in the blanks
+       ```python
+       instructions = '''
+       Respond in this format:
+       PRODUCT: [name]
+       PRICE: $[amount]
+       VERDICT: [recommendation]
+       '''
+       ```
+    
+    3. **Pydantic Validation**
+       - Parse agent output with Pydantic
+       - Retry if validation fails
+       ```python
+       response = agent.chat(query)
+       try:
+           result = ProductInfo.model_validate_json(response)
+       except ValidationError:
+           # Retry with clarification
+       ```
+    
+    4. **Output Parsers**
+       - Post-process agent output
+       - Extract structured data from text
+       ```python
+       def parse_product(text: str) -> dict:
+           # Extract price, rating, etc.
+           return structured_data
+       ```
+    
+    5. **Few-Shot Examples**
+       - Show examples of desired output format
+       - Agent learns pattern from examples
+       ```python
+       instructions = '''
+       Example:
+       Q: Tell me about Product X
+       A: {"name": "Product X", "price": 99.99}

 PraisonAI provides a complete knowledge stack for building RAG applications with multiple vector stores, retrieval strategies, rerankers, and query modes.
 
+### RAG Quickstart (Agent-first)
+
+```python
+from praisonaiagents import Agent
+from praisonaiagents.rag.models import RetrievalStrategy
+
+# Agent with RAG - simplest approach
+agent = Agent(
+    name="Research Assistant",
+    knowledge=["docs/manual.pdf", "data/faq.txt"],
+    knowledge_config={"vector_store": {"provider": "chroma"}},
+    rag_config={
+        "include_citations": True,
+        "retrieval_strategy": RetrievalStrategy.HYBRID,  # Dense + BM25
+        "rerank": True,
+    }
+)
+
+# Query with citations
+result = agent.rag_query("How do I authenticate?")
+print(result.answer)
+for citation in result.citations:
+    print(f"  [{citation.id}] {citation.source}")
+```
+
+### RAG CLI Commands
+
+| Command | Description |
+|---------|-------------|
+| `praisonai rag query "<question>"` | One-shot question answering with citations |
+| `praisonai rag chat` | Interactive RAG chat session |
+| `praisonai rag serve` | Start RAG as a microservice API |
+| `praisonai rag eval <test_file>` | Evaluate RAG retrieval quality |
+
+### RAG CLI Examples
+
+```bash
+# Query with hybrid retrieval (dense + BM25 keyword search)
+praisonai rag query "What are the key findings?" --hybrid
+
+# Query with hybrid + reranking for best quality
+praisonai rag query "Summarize conclusions" --hybrid --rerank
+
+# Interactive chat with hybrid retrieval
+praisonai rag chat --collection research --hybrid --rerank
+
+# Start API server with OpenAI-compatible endpoint
+praisonai rag serve --hybrid --rerank --openai-compat --port 8080
+
+# Query with profiling
+praisonai rag query "Summary?" --profile --profile-out ./profile.json
+```
+

-### Knowledge SDK Usage
+### Knowledge vs RAG vs AutoRagAgent
+
+- **Knowledge** is the indexing and retrieval substrate - use for indexing and raw search
+- **RAG** orchestrates on top - use for question answering with LLM-generated responses and citations
+- **AutoRagAgent** wraps an Agent with automatic retrieval decision - use when you want the agent to decide when to retrieve
+- All share the same underlying index
+
+### AutoRagAgent (Automatic RAG)
+
+AutoRagAgent automatically decides when to retrieve context from knowledge bases vs direct chat, based on query heuristics.
 
 ```python
-from praisonaiagents import Agent, Knowledge
+from praisonaiagents import Agent, AutoRagAgent
 
-# Simple usage with Agent
+# Create agent with knowledge
 agent = Agent(
     name="Research Assistant",
-    knowledge=["docs/manual.pdf", "data/faq.txt"],
-    knowledge_config={
-        "vector_store": {"provider": "chroma"}
-    }
+    knowledge=["docs/manual.pdf"],
+    user_id="user123",  # Required for RAG retrieval
 )
-response = agent.chat("How do I authenticate?")
 
-# Direct Knowledge usage
-knowledge = Knowledge()
-knowledge.add("document.pdf")
-results = knowledge.search("authentication", limit=5)
+# Wrap with AutoRagAgent
+auto_rag = AutoRagAgent(
+    agent=agent,
+    retrieval_policy="auto",  # auto, always, never
+    top_k=5,
+    hybrid=True,
+    rerank=True,
+)
+
+# Auto-decides: retrieves for questions, skips for greetings
+result = auto_rag.chat("What are the key findings?")  # Retrieves
+result = auto_rag.chat("Hello!")  # Skips retrieval
+
+# Force retrieval or skip per-call
+result = auto_rag.chat("Hi", force_retrieval=True)
+result = auto_rag.chat("Summary?", skip_retrieval=True)
+```
+
+**CLI Usage:**
+```bash
+# Enable auto-rag with default policy (auto)
+praisonai --auto-rag "What are the key findings?"
+
+# Always retrieve
+praisonai --auto-rag --rag-policy always "Tell me about X"
+
+# With hybrid retrieval and reranking
+praisonai --auto-rag --rag-hybrid --rag-rerank "Summarize the document"
+```
+
+### Configuration Precedence
+
+Settings are applied in this order (highest priority first):
+1. **CLI flags** - `--hybrid`, `--rerank`, `--top-k`
+2. **Environment variables** - `PRAISONAI_HYBRID=true`
+3. **Config file** - YAML configuration (`--config`)
+4. **Defaults**
+
+```bash
+# Environment variables
+export PRAISONAI_HYBRID=true
+export PRAISONAI_RERANK=true
+export PRAISONAI_TOP_K=10
+```
+
+### Lightweight Installs
+
+```bash
+# Base install (minimal, fast imports)
+pip install praisonaiagents
+
+# With RAG API server support
+pip install "praisonai[rag-api]"
+```
+
+### Live Tests (Real API Keys)
+
+Run integration tests with real API keys:
+
+```bash
+# Enable live tests
+export PRAISONAI_LIVE_TESTS=1
+export OPENAI_API_KEY="your-key"
+
+# Run live tests
+pytest -m live tests/integration/
 ```
