 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

-### 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/

+# Profiling CLI
+
+PraisonAI provides unified profiling capabilities for performance analysis and debugging, with **full visibility from ENTER to first response**.
+
+## Quick Start
+
+```bash
+# Basic profiling
+praisonai "What is 2+2?" --profile
+
+# Deep profiling with call graph, decision trace, and module breakdown
+praisonai "What is 2+2?" --profile --profile-deep
+
+# JSON output format
+praisonai "What is 2+2?" --profile --profile-format json
+```
+
+## Time to First Response (TTFR)
+
+**TTFR** is the key user-perceived latency metric. It measures the time from when you press ENTER until the first visible output appears.
+
+### What contributes to TTFR?
+
+1. **CLI Entry** - Time to reach the CLI entry point
+2. **CLI Parse** - Argparse/Typer routing time
+3. **Routing** - Command routing to handler
+4. **Imports** - Loading required modules
+5. **Agent Init** - Initializing the agent
+6. **Network Request** - Sending request to LLM API
+7. **First Token** - Receiving first token (streaming)
+8. **First Output** - Rendering first visible output
+
+### How to reduce TTFR
+
+1. **Warm runs** - Imports are cached after first run
+2. **Streaming mode** - See output as tokens arrive
+3. **Lighter models** - Faster response times
+4. **Local models** - Eliminate network latency
+
+## CLI Flags
+
+| Flag | Description | Default |
+|------|-------------|---------|
+| `--profile` | Enable profiling with timing breakdown | Disabled |
+| `--profile-deep` | Enable deep profiling with call graph (higher overhead) | Disabled |
+| `--profile-format` | Output format: `text` or `json` | `text` |
+
+## Profile Command
+
+For more detailed profiling options, use the `profile` subcommand:
+
+```bash
+# Profile a query
+praisonai profile query "What is 2+2?"
+
+# With deep call tracing
+praisonai profile query "Hello" --deep
+
+# Limit functions shown
+praisonai profile query "Test" --limit 20
+
+# Save artifacts to directory
+praisonai profile query "Test" --save ./profile_results
+
+# JSON output
+praisonai profile query "Test" --format json
+```
+
+### Profile Query Options
+
+| Option | Description | Default |
+|--------|-------------|---------|
+| `--model, -m` | Model to use | Default model |
+| `--stream/--no-stream` | Use streaming mode | No stream |
+| `--deep` | Enable deep call tracing | Disabled |
+| `--limit, -n` | Top N functions to show | 30 |
+| `--sort, -s` | Sort by: `cumulative` or `tottime` | `cumulative` |
+| `--show-callers` | Show caller functions | Disabled |
+| `--show-callees` | Show callee functions | Disabled |
+| `--save` | Save artifacts to path | None |
+| `--format, -f` | Output format: `text` or `json` | `text` |
+
+## Other Profile Commands
+
+```bash
+# Profile module import times
+praisonai profile imports
+
+# Profile CLI startup time
+praisonai profile startup
+
+# Run comprehensive profiling suite
+praisonai profile suite
+
+# Create performance snapshots for comparison
+praisonai profile snapshot --baseline
+praisonai profile snapshot current --compare

+## Profiling Layers
+
+| Layer | Overhead | Features |
+|-------|----------|----------|
+| 0 | < 1ms | Wall-clock phases only |
+| 1 | ~5% | + cProfile function stats |
+| 2 | ~15% | + Call graph (callers/callees) |
+
+- `--profile` uses Layer 1
+- `--profile --profile-deep` uses Layer 2
+
+## Performance Tips
+
+1. **Use Layer 0 for production monitoring** - minimal overhead
+2. **Use Layer 1 for development profiling** - good balance
+3. **Use Layer 2 only for deep debugging** - higher overhead
+
+## Observational Equivalence
+
+The following commands produce equivalent profile reports:
+
+```bash
+# CLI direct
+praisonai "prompt" --profile
+
+# Profile command
+praisonai profile query "prompt"
+```
+
+Both use the same unified profiling architecture and produce identical schema output.

+
+config = ProfilerConfig(layer=1)
+profiler = Profiler(config)
+
+request = ExecutionRequest(prompt="Hello")
+result, report = profiler.profile_sync(request, invocation_method="api")
+```
+
+### Methods
+
+#### `profile_sync(request, invocation_method="profile_command")`
+
+Profile synchronous execution.
+
+**Parameters:**
+- `request`: ExecutionRequest - The execution request
+- `invocation_method`: str - How this was invoked (for report)
+
+**Returns:** Tuple of (ExecutionResult, ProfileReport)
+
+## ProfileReport
+
+The canonical profile report with timing and statistics.
+
+```python
+# Access timing breakdown
+print(f"Total: {report.timing.total_ms}ms")
+print(f"Imports: {report.timing.imports_ms}ms")
+print(f"Agent Init: {report.timing.agent_init_ms}ms")
+print(f"Execution: {report.timing.execution_ms}ms")
+
+# Access function stats (layer 1+)
+if report.functions:
+    for func in report.functions[:5]:
+        print(f"{func.name}: {func.cumulative_time_ms}ms")
+
+# Access call graph (layer 2)
+if report.call_graph:
+    print(f"Edges: {len(report.call_graph.edges)}")
+
+# Export formats
+json_str = report.to_json()
+text_str = report.to_text()
+dict_data = report.to_dict()
+```
+
+### Schema Version
+
+The report uses schema version `1.0`. Schema is frozen after release - new fields are always optional with defaults.
+
+### Mandatory Fields
+
+- `schema_version`: str
+- `run_id`: str
+- `timestamp`: str (ISO 8601)
+- `invocation`: InvocationInfo
+- `timing`: TimingBreakdown
+- `response_preview`: str
+
+### Optional Fields
+
+- `functions`: List[FunctionStat] (layer 1+)
+- `call_graph`: CallGraph (layer 2)
+- `network`: List[RequestTiming] (if track_network)
+
+## ExecutionResult
+
+Result of execution with output and metadata.
+
+```python
+# Access output
+print(result.output)
+print(result.success)
+print(result.run_id)
+
+# Check for errors
+if result.error:
+    print(f"Error: {result.error}")
+
+# Duration
+print(f"Duration: {result.duration_ms}ms")
+```
+
+## Data Bounds
+
+Profile data is strictly bounded to prevent memory issues:
+
+| Data Type | Maximum |
+|-----------|---------|
+| Function stats | 1000 |
+| Call graph edges | 5000 |
+| Network requests | 100 |
+
+## Example: Full Profiling Workflow
+
+```python
+from praisonai.cli.execution import (
+    ExecutionRequest,
+    Profiler,
+    ProfilerConfig,
+)
+
+# Configure deep profiling
+config = ProfilerConfig(
+    layer=2,
+    limit=50,
+    show_callers=True,
+    show_callees=True,
+)
+
+# Create request
+request = ExecutionRequest(
+    prompt="Explain quantum computing in simple terms",
+    model="gpt-4",
+)
+
+# Profile execution
+profiler = Profiler(config)
+result, report = profiler.profile_sync(request)
+
+# Print text report
+print(report.to_text())
+
+# Save JSON report
+with open("profile.json", "w") as f:
+    f.write(report.to_json())
+
+# Analyze timing
+print(f"\nTiming Analysis:")
+print(f"  Import overhead: {report.timing.imports_ms / report.timing.total_ms * 100:.1f}%")
+print(f"  Execution time: {report.timing.execution_ms / report.timing.total_ms * 100:.1f}%")
+
+# Top 5 hotspots
+if report.functions:
+    print(f"\nTop 5 Hotspots:")
+    for func in report.functions[:5]:
+        print(f"  {func.name}: {func.cumulative_time_ms:.2f}ms ({func.calls} calls)")
+```
+
+## Invariants
+
+The profiling module guarantees:
+
+1. **Output Equivalence**: Profiled execution produces identical output to non-profiled execution
+2. **Schema Stability**: Schema version 1.0 is frozen; new fields are always optional
+3. **Bounded Data**: All profile data respects maximum bounds
+4. **Zero Overhead When Disabled**: No profiling code runs unless explicitly enabled

+# ACP (Agent Client Protocol) Examples
+
+This directory contains examples for using PraisonAI with the Agent Client Protocol (ACP).
+
+## What is ACP?
+
+The Agent Client Protocol (ACP) is a standardized JSON-RPC 2.0 protocol that allows code editors and IDEs to communicate with AI coding agents. It enables seamless integration between PraisonAI and editors like:
+
+- **Zed**
+- **JetBrains IDEs** (IntelliJ, PyCharm, WebStorm, etc.)
+- **VSCode** (via extensions)
+- **Toad**
+
+## Quick Start
+
+### CLI Usage
+
+```bash
+# Start ACP server with defaults
+praisonai acp
+
+# Enable debug logging
+praisonai acp --debug
+
+# Allow file writes
+praisonai acp --allow-write
+
+# Use a specific model
+praisonai acp -m gpt-4o
+
+# Resume last session
+praisonai acp --resume --last
+```
+
+### Python API
+
+```python
+from praisonai.acp import serve
+
+serve(
+    workspace=".",
+    debug=True,
+    allow_write=True,
+)
+```
+
+## Editor Configuration
+
+### Zed
+
+Add to `~/.config/zed/settings.json`:
+
+```json
+{
+  "agent_servers": {
+    "PraisonAI": {
+      "command": "praisonai",
+      "args": ["acp"],
+      "env": {}
+    }
+  }
+}
+```
+
+### JetBrains
+
+Add to `~/.jetbrains/acp.json`:
+
+```json
+{
+  "agent_servers": {
+    "PraisonAI": {
+      "command": "praisonai",
+      "args": ["acp"],
+      "env": {}
+    }
+  }
+}
+```
+
+### Toad
+
+```bash
+toad acp "praisonai acp"
+```
+
+## Examples
+
+- `basic_acp_server.py` - Simple ACP server with default settings
+- `custom_agent_acp.py` - ACP server with a custom agent
+
+## CLI Options
+
+| Option | Description |
+|--------|-------------|
+| `-w, --workspace` | Workspace root directory |
+| `-a, --agent` | Agent name or config file |
+| `-m, --model` | LLM model to use |
+| `-r, --resume` | Resume session by ID |
+| `--last` | Resume the last session |
+| `--approve` | Approval mode: manual, auto, scoped |
+| `--read-only` | Read-only mode (default) |
+| `--allow-write` | Allow file writes |
+| `--allow-shell` | Allow shell commands |
+| `--debug` | Enable debug logging |
+
+## Installation
+
+```bash
+pip install praisonai[acp]
+```
+
+## Protocol Details
+
+ACP uses JSON-RPC 2.0 over stdio:
+- **stdin**: Receives JSON-RPC requests from the client
+- **stdout**: Sends JSON-RPC responses to the client
+- **stderr**: Debug/log output (never pollutes stdout)
+
+### Supported Methods
+
+**Agent Methods (client → agent):**
+- `initialize` - Negotiate protocol version and capabilities
+- `authenticate` - Optional authentication
+- `session/new` - Create a new session
+- `session/load` - Load an existing session
+- `session/prompt` - Send user message
+- `session/cancel` - Cancel ongoing operations
+- `session/set_mode` - Change operating mode
+
+**Client Methods (agent → client):**
+- `session/update` - Send progress updates
+- `session/request_permission` - Request user approval
+- `fs/read_text_file` - Read file contents
+- `fs/write_text_file` - Write file contents
+- `terminal/create` - Create terminal
+- `terminal/output` - Get terminal output

+# PraisonAI Profiling Examples
+
+This directory contains examples for profiling PraisonAI agent performance.
+
+## Prerequisites
+
+```bash
+pip install praisonai
+export OPENAI_API_KEY=your_key_here
+```
+
+## Examples
+
+### 1. Basic Profiling (`basic_profiling.py`)
+
+Demonstrates programmatic profiling of a single query:
+
+```bash
+python basic_profiling.py
+```
+
+### 2. Suite Profiling (`suite_profiling.py`)
+
+Runs a comprehensive profiling suite with multiple scenarios:
+
+```bash
+python suite_profiling.py
+```
+
+### 3. Optimization Demo (`optimization_example.py`)
+
+Demonstrates Tier 0/1/2 performance optimizations:
+
+```bash
+python optimization_example.py
+```
+
+## CLI Commands
+
+You can also profile directly from the command line:
+
+```bash
+# Profile a query
+praisonai profile query "What is 2+2?"
+
+# Profile with file grouping
+praisonai profile query "Hello" --show-files --limit 20
+
+# Profile imports
+praisonai profile imports
+
+# Profile startup time
+praisonai profile startup
+
+# Run comprehensive suite
+praisonai profile suite --quick
+
+# Create performance baseline
+praisonai profile snapshot --baseline
+
+# Compare against baseline
+praisonai profile snapshot current --compare
+
+# Show optimization status
+praisonai profile optimize --show
+```
+
+## Output
+
+- **Text output**: Human-readable timing breakdown
+- **JSON output**: Machine-readable for CI/CD (`--format json`)
+- **Artifacts**: Binary cProfile data and reports (`--save ./results`)
+- **Snapshots**: Performance baselines for regression detection
+
+## Performance Optimizations
+
+Enable opt-in optimizations via environment variables:
+
+```bash
+export PRAISONAI_LITE_MODE=1
+export PRAISONAI_SKIP_TYPE_VALIDATION=1
+export PRAISONAI_MINIMAL_IMPORTS=1
+```

+# RAG Examples
+
+This directory contains comprehensive examples demonstrating RAG (Retrieval Augmented Generation) with PraisonAI Agents.
+
+## Core RAG Concepts
+
+| Example | Description | Key Concepts |
+|---------|-------------|--------------|
+| `basic_retrieval.py` | Fundamental retrieve-then-generate pattern | Knowledge base, context injection |
+| `auto_retrieval.py` | Intelligent retrieval decisions with AutoRagAgent | Conditional RAG, retrieval policies |
+| `chunking_strategies.py` | Document splitting approaches | Paragraph, section, fixed-size chunking |
+| `hybrid_search.py` | Dense + sparse retrieval combination | Semantic search, keyword matching |
+| `reranking.py` | Two-stage retrieval with reranking | Precision optimization, cross-encoders |
+
+## Advanced RAG Patterns
+
+| Example | Description | Key Concepts |
+|---------|-------------|--------------|
+| `multi_document.py` | Synthesizing across multiple sources | Cross-referencing, source diversity |
+| `knowledge_graph.py` | Relationship-aware retrieval | Entity connections, multi-hop reasoning |
+| `external_sources.py` | Web, API, and database augmentation | Real-time data, hybrid sources |
+| `structured_output.py` | Guided and constrained generation | JSON output, Pydantic schemas |
+| `retrieval_policies.py` | Agent-decided retrieval strategies | Adaptive top-k, priority filtering |
+| `citations.py` | Source attribution and verification | Inline citations, verification |
+
+## Application Examples
+
+### PDF Q&A (`rag_pdf_qa.py`)
+
+Basic RAG example showing how to:
+- Use Agent with knowledge parameter
+- Create explicit RAG pipeline with citations
+- Stream responses
+
+```bash
+python rag_pdf_qa.py
+```
+
+### Multi-Agent RAG (`rag_multi_agent.py`)
+
+Advanced example showing:
+- Shared knowledge base across multiple agents
+- Collaborative RAG workflow
+- Sequential task processing
+
+```bash
+python rag_multi_agent.py
+```
+
+### RAG Evaluation (`rag_evaluation.py`)
+
+Evaluation example showing:
+- Golden query testing
+- Retrieval accuracy metrics
+- Answer relevance checking
+
+```bash
+python rag_evaluation.py
+```
+
+## Quick Start
+
+Run any example:
+
+```bash
+# Basic RAG
+python basic_retrieval.py
+
+# Auto RAG with intelligent decisions
+python auto_retrieval.py
+
+# Hybrid search (dense + sparse)
+python hybrid_search.py
+
+# RAG with citations
+python citations.py
+```
+
+## Installation
+
+```bash
+pip install "praisonaiagents[knowledge]"
+```
+
+## CLI Usage
+
+```bash
+# Index documents
+praisonai rag index ./documents --collection my_docs
+
+# Query
+praisonai rag query "What is the main finding?" --collection my_docs
+
+# Interactive chat
+praisonai rag chat --collection my_docs
+
+# Evaluate
+praisonai rag eval golden_queries.json --collection my_docs
+```
+
+## Configuration
+
+Create `rag_config.yaml`:
+
+```yaml
+knowledge:
+  collection: my_docs
+  chunking:
+    strategy: recursive
+    chunk_size: 512
+
+rag:
+  top_k: 5
+  min_score: 0.3
+  include_citations: true
+```
+
+Use with:
+```bash

+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

+    📚 Best Practices for RAG Citations:

+    1. **Include Metadata in Knowledge Base**

+       documents = [
+           {
+               "id": "doc_001",
+               "source": "Policy Manual",
+               "section": "Chapter 3",

+               "author": "HR Department",
+               "content": "..."
+           }
+       ]
+       ```
+    
+    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

+    📊 Graph-Assisted RAG Patterns:
+    
+    1. **Entity-Centric Retrieval**
+       - Store entities with their relationships
+       - Query retrieves entity + connected entities
+       - Good for: "Tell me about X and its connections"
+    
+    2. **Path-Based Retrieval**
+       - Find paths between two entities
+       - Retrieve all nodes along the path
+       - Good for: "How is X related to Y?"
+    
+    3. **Neighborhood Expansion**
+       - Start with query-matched entities
+       - Expand to include 1-hop or 2-hop neighbors
+       - Good for: Comprehensive context
+    
+    4. **Subgraph Extraction**
+       - Extract relevant subgraph for query
+       - Include nodes and edges as context
+       - Good for: Complex multi-entity questions

+# Research Study: Impact of Remote Work on Productivity
+
+## Abstract
+This study examines the effects of remote work arrangements on employee 
+productivity across 50 technology companies during 2023-2024.
+
+## Methodology
+- Survey of 5,000 employees across 50 companies
+- Productivity metrics tracked over 12 months
+- Control group: in-office workers
+- Test group: remote and hybrid workers
+
+## Key Findings
+
+### Productivity Impact
+- Remote workers showed 13% higher productivity on average
+- Hybrid workers (3 days remote) showed 18% higher productivity
+- Fully remote workers reported 25% better work-life balance
+
+### Challenges Identified
+- Communication delays increased by 15%
+- Collaboration on complex projects took 10% longer
+- New employee onboarding was 20% slower remotely
+
+### Cost Analysis
+- Companies saved average of $11,000 per remote employee annually
+- Employees saved average of $4,500 in commuting costs
+- Office space reduction saved 30% on real estate costs
+
+## Recommendations
+1. Implement hybrid work model (2-3 days remote)
+2. Invest in collaboration tools
+3. Create structured onboarding for remote hires
+4. Establish clear communication protocols
+
+## Conclusion
+Remote work, when properly implemented, leads to improved productivity
+and significant cost savings for both employers and employees.

+    🎯 Constrained Generation Techniques:

+    1. **Schema Enforcement**

+       - 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 = '''

+
+PraisonAI is an AI agents framework that enables building sophisticated AI applications.
+
+## Key Features
+
+1. **Agent-First Design**: Everything centers around the Agent class
+2. **Knowledge Integration**: Agents can use knowledge bases for retrieval
+3. **Unified Configuration**: Single retrieval_config for all retrieval settings
+4. **Multi-Agent Support**: Multiple agents can share knowledge
+
+## Retrieval Policies
+
+- **auto**: Automatically decide when to retrieve based on query
+- **always**: Always retrieve for every query
+- **never**: Never retrieve (use for pure generation)
+
+## Citation Modes
+
+- **append**: Add citations at the end of the response
+- **inline**: Include citations inline in the text
+- **hidden**: Citations available in result but not in text

+Event Bus Module for PraisonAI Agents.
+
+Provides a typed publish/subscribe event system for real-time communication
+between components. Extends the existing hooks system with a more general
+event-driven architecture.
+
+Features:
+- Typed event definitions with dataclass payloads
+- Sync and async subscribers
+- Event filtering by type
+- Global and scoped event buses
+- SSE-compatible event streaming
+
+Zero Performance Impact:
+- All imports are lazy loaded
+- No overhead when not subscribed
+- Optional dependency for server features
+
+Usage:
+    from praisonaiagents.bus import EventBus, Event
+    
+    # Create event bus
+    bus = EventBus()
+    
+    # Subscribe to events
