-            You are an expert code reviewer. You have access to shell commands to gather PR information and perform the review.
+            You are an expert code reviewer and AI assistant for Pull Requests. You can review code AND make modifications to improve the PR.
 
-            IMPORTANT: Use the available shell commands to gather information. Do not ask for information to be provided.
+            **PR Details:**
+            - PR Number: #$PR_NUMBER
+            - Repository: $REPOSITORY
+            - Additional Instructions: $ADDITIONAL_INSTRUCTIONS
 
-            Start by running these commands to gather the required data:
-            1. Run: echo "$PR_DATA" to get PR details (JSON format)
-            2. Run: echo "$CHANGED_FILES" to get the list of changed files
-            3. Run: echo "$PR_NUMBER" to get the PR number
-            4. Run: echo "$ADDITIONAL_INSTRUCTIONS" to see any specific review instructions from the user
-            5. Run: gh pr diff $PR_NUMBER to see the full diff
-            6. For any specific files, use: cat filename, head -50 filename, or tail -50 filename
-            
-            Additional Review Instructions:
-            If ADDITIONAL_INSTRUCTIONS contains text, prioritize those specific areas or focus points in your review.
-            Common instruction examples: "focus on security", "check performance", "review error handling", "check for breaking changes"
-            
-            Once you have the information, provide a comprehensive code review by:
-            1. Writing your review to a file: write_file("review.md", "<your detailed review feedback here>")
-            2. Posting the review: gh pr comment $PR_NUMBER --body-file review.md --repo $REPOSITORY
+            **CRITICAL: When making code modifications, follow this EXACT workflow:**
+
+            **STEP 1: Analyze the PR**
+            - Use: `echo "$PR_DATA"` to get PR details (JSON format)
+            - Use: `echo "$CHANGED_FILES"` to get changed files list
+            - Use: `gh pr diff ${PR_NUMBER}` to see the full diff
+            - Use: `gh pr view ${PR_NUMBER} --json title,body,headRefName` to get PR info
+            - Analyze the code changes thoroughly
+
+            **STEP 2: If Code Improvements Are Needed**
+            **IMPORTANT:** DO NOT create a new branch! Work on the EXISTING PR branch.
+            - Use: `git fetch origin` to get latest changes
+            - Get PR branch name: `gh pr view ${PR_NUMBER} --json headRefName`
+            - Switch to PR branch: `git checkout BRANCH_NAME` (use actual branch name from PR)
+            - Use: `git pull origin BRANCH_NAME` to get latest PR changes
+
+            **STEP 3: Make Code Modifications**
+            - Use `read_file` to examine existing code
+            - Use `write_file` or `replace` to make improvements
+            - Use `search_file_content` to find related code
+            - Make focused, targeted improvements to the PR
+
+            **STEP 4: Test Changes (if applicable)**
+            - Run relevant tests if test files exist
+            - Use `run_shell_command` to execute test commands
+
+            **STEP 5: Commit and Push Changes to EXISTING PR Branch**
+            - Use: `git add .` (or specific files)
+            - Use: `git commit -m "Gemini: [PR #${PR_NUMBER}] Brief description of improvements"`
+            - Use: `git push origin BRANCH_NAME` (push to EXISTING PR branch)
+
+            **STEP 6: Review and Comment on PR**
+            Write comprehensive review and post comment with your analysis and any improvements made.
+            Use: `gh pr comment ${PR_NUMBER} -b "MESSAGE"`
 
             Review Guidelines:
             - Focus on code quality, security, performance, and maintainability

-Validation Feedback Feature Demonstration
-==========================================
-
-This example shows how the workflow retry logic now includes validation feedback.
-
-Before: When validation failed, the retry task would start fresh without knowing why it failed.
-After: The retry task receives detailed feedback about what went wrong.
-
-Example Scenario:
-1. A data collection task produces output
-2. A validation task checks if the output meets criteria
-3. If validation fails, the data collection task is retried WITH feedback about why it failed
-
-The retry task will see:
-- Previous attempt failed validation with reason: invalid
-- Validation feedback: [specific reason for failure]
-- Rejected output: [the output that failed validation]
-- Please try again with a different approach based on this feedback.
-
-This enables context-dependent tasks to improve on retry instead of repeating the same mistakes.
-==========================================
-
-Implementation Details:
-1. Added 'validation_feedback' field to Task class
-2. When routing from decision task to retry task, capture validation details
-3. Include feedback in task context when building retry task description
-4. Clear feedback after use to prevent persistence
-
-The solution is minimal and backward compatible - existing workflows continue to work unchanged.

+# Multi-Provider/Multi-Model Support
+
+PraisonAI now supports intelligent multi-provider and multi-model capabilities, allowing agents to automatically select the most appropriate AI model based on task requirements, cost considerations, and performance needs.
+
+## 🚀 Key Features
+
+### 1. **Automatic Model Selection**
+- Analyzes task complexity and selects the best model
+- Considers cost vs. performance trade-offs
+- Supports fallback mechanisms for reliability
+
+### 2. **Cost Optimization**
+- Routes simple tasks to cheaper models (e.g., GPT-4o-mini, Gemini Flash)
+- Reserves expensive models for complex tasks
+- Tracks usage and provides cost estimates
+
+### 3. **Multi-Provider Support**
+- Works with OpenAI, Anthropic, Google, Groq, and more
+- Seamless switching between providers
+- Provider preference settings
+
+### 4. **Flexible Routing Strategies**
+- `auto`: Automatic selection based on task analysis
+- `cost-optimized`: Prioritize cheaper models
+- `performance-optimized`: Prioritize capability
+- `manual`: Use specified model
+
+## 📦 Installation
+
+The multi-provider support is included in the standard installation:
+
+```bash
+pip install praisonaiagents
+```
+
+## 🔧 Basic Usage
+
+### Simple Multi-Model Agent
+
+```python
+from praisonaiagents import Task, PraisonAIAgents
+from praisonaiagents.agent import RouterAgent
+
+# Create a multi-model agent
+agent = RouterAgent(
+    name="Smart Assistant",
+    role="Adaptive AI Assistant",
+    goal="Complete tasks using the most appropriate model",
+    models=["gpt-4o-mini", "gpt-4o", "claude-3-5-sonnet-20241022"],
+    routing_strategy="auto"  # Automatic model selection
+)
+
+# Create tasks
+simple_task = Task(
+    name="calculate",
+    description="What is 15% of 250?",
+    agent=agent
+)
+
+complex_task = Task(
+    name="analyze",
+    description="Write a Python implementation of the A* pathfinding algorithm",
+    agent=agent
+)
+
+# Run tasks - agent will automatically select appropriate models
+agents = PraisonAIAgents(
+    agents=[agent],
+    tasks=[simple_task, complex_task]
+)
+
+results = agents.start()
+```
+
+### Cost-Optimized Workflow
+
+```python
+from praisonaiagents.llm import ModelRouter
+
+# Create custom router with cost constraints
+router = ModelRouter(
+    cost_threshold=0.005,  # Max $0.005 per 1k tokens
+    preferred_providers=["google", "openai"]
+)
+
+# Create cost-conscious agent
+analyzer = RouterAgent(
+    name="Budget Analyzer",
+    role="Data Analyst",
+    goal="Analyze data efficiently",
+    models={
+        "gemini/gemini-1.5-flash": {},
+        "gpt-4o-mini": {},
+        "claude-3-haiku-20240307": {}
+    },
+    model_router=router,
+    routing_strategy="cost-optimized"
+)
+```
+
+## 🎯 Routing Strategies
+
+### Auto Routing (Default)
+Automatically selects models based on:
+- Task complexity analysis
+- Required capabilities (tools, vision, etc.)
+- Context size requirements
+- Cost/performance balance
+
+### Cost-Optimized
+Prioritizes cheaper models while meeting task requirements:
+- Uses lightweight models for simple tasks
+- Only escalates to expensive models when necessary
+- Ideal for high-volume operations
+
+### Performance-Optimized
+Prioritizes model capability:
+- Uses the best available model for the task
+- Ideal for quality-critical applications
+- Less concern for cost
+
+### Manual
+Uses the specified model without routing:
+- Direct control over model selection
+- Useful for testing or specific requirements
+
+## 📊 Model Profiles
+
+The system includes pre-configured profiles for popular models:
+
+| Model | Provider | Best For | Cost/1k tokens |
+|-------|----------|----------|----------------|
+| gpt-4o-mini | OpenAI | Simple tasks, speed | $0.00075 |
+| gemini-1.5-flash | Google | Cost-effective, multimodal | $0.000125 |
+| claude-3-haiku | Anthropic | Fast responses | $0.0008 |
+| gpt-4o | OpenAI | General purpose | $0.0075 |
+| claude-3-5-sonnet-20241022 | Anthropic | Complex reasoning | $0.009 |
+| deepseek-chat | DeepSeek | Code & math | $0.0014 |
+
+## 🔍 Task Complexity Analysis
+
+The system analyzes tasks to determine complexity:
+
+- **Simple**: Basic calculations, definitions, yes/no questions
+- **Moderate**: Summarization, basic analysis, classification
+- **Complex**: Code generation, algorithm implementation
+- **Very Complex**: Multi-step reasoning, system design
+
+## 📈 Usage Tracking
+
+Track model usage and costs:
+
+```python
+# Get usage report
+report = agent.get_usage_report()
+print(report)
+
+# Output:
+{
+    'agent_name': 'Smart Assistant',
+    'routing_strategy': 'auto',
+    'model_usage': {
+        'gpt-4o-mini': {'calls': 5, 'tokens': 1500, 'cost': 0.0011},
+        'gpt-4o': {'calls': 2, 'tokens': 3000, 'cost': 0.0225}
+    },
+    'total_cost_estimate': 0.0236,
+    'total_calls': 7
+}
+```
+
+## 🛠️ Custom Model Configuration
+
+Add custom model profiles:
+
+```python
+from praisonaiagents.llm import ModelProfile, TaskComplexity
+
+custom_model = ModelProfile(
+    name="custom-model",
+    provider="custom",
+    complexity_range=(TaskComplexity.SIMPLE, TaskComplexity.MODERATE),
+    cost_per_1k_tokens=0.002,
+    strengths=["domain-specific"],
+    capabilities=["text"],
+    context_window=32000
+)
+
+router = ModelRouter(models=[custom_model])
+```
+
+## 🔗 Integration with AutoAgents
+
+Works seamlessly with AutoAgents:
+
+```python
+from praisonaiagents.agents import AutoAgents
+
+# Create auto agents
+auto = AutoAgents(
+    instructions="Analyze market trends and create a report",
+    max_agents=3
+)
+
+# Convert to multi-model agents
+for i, agent in enumerate(auto.agents):
+    auto.agents[i] = RouterAgent(
+        name=agent.name,
+        role=agent.role,
+        goal=agent.goal,
+        models=["gpt-4o-mini", "gpt-4o", "claude-3-5-sonnet"],
+        routing_strategy="auto"
+    )
+
+results = auto.start()
+```
+
+## 🌟 Best Practices
+
+1. **Start with Auto Routing**: Let the system learn your needs
+2. **Monitor Costs**: Use usage reports to optimize
+3. **Set Cost Thresholds**: Prevent unexpected expenses
+4. **Use Appropriate Models**: Don't use GPT-4 for simple math
+5. **Leverage Fallbacks**: Configure fallback models for reliability
+
+## 🔐 Environment Variables
+
+Set API keys for each provider:
+
+```bash
+export OPENAI_API_KEY="sk-..."
+export ANTHROPIC_API_KEY="sk-ant-..."
+export GEMINI_API_KEY="..."
+export GROQ_API_KEY="..."
+```
+
+## 🤝 Contributing
+
+The multi-provider system is extensible. To add new models:
+
+1. Add model profile to `ModelRouter.DEFAULT_MODELS`
+2. Ensure the provider is supported by LiteLLM
+3. Test with various task complexities

+# Gemini Embedding Support in PraisonAI
+
+This document describes how to use Google's Gemini embedding models with PraisonAI's memory system.
+
+## Overview
+
+PraisonAI now supports configurable embedding models through LiteLLM, including Google's Gemini embedding models. This allows you to use models like `text-embedding-004` or `gemini-embedding-exp-03-07` for semantic search and memory storage.
+
+## Configuration
+
+### Default Configuration (OpenAI)
+
+By default, PraisonAI uses OpenAI's `text-embedding-3-small` model:
+
+```python
+from praisonaiagents import PraisonAIAgents
+
+agents = PraisonAIAgents(
+    agents=[...],
+    tasks=[...],
+    memory=True  # Uses default OpenAI embeddings
+)
+```
+
+### Using Gemini Embeddings
+
+To use Gemini embeddings, configure the `embedder` parameter:
+
+```python
+from praisonaiagents import PraisonAIAgents
+
+agents = PraisonAIAgents(
+    agents=[...],
+    tasks=[...],
+    memory=True,
+    embedder={
+        "provider": "gemini",
+        "config": {
+            "model": "text-embedding-004"  # or "gemini-embedding-exp-03-07"
+        }
+    }
+)
+```
+
+## Prerequisites
+
+1. **API Key**: Set your Google API key:
+   ```bash
+   export GOOGLE_API_KEY='your-api-key'
+   ```
+
+2. **Dependencies**: Ensure you have the memory dependencies installed:
+   ```bash
+   pip install "praisonaiagents[memory]"
+   ```
+
+## Supported Models
+
+### Gemini Embedding Models
+
+- `text-embedding-004` - Stable embedding model
+- `gemini-embedding-exp-03-07` - Experimental model with advanced features
+
+### Task Types (Optional)
+
+Gemini models support task-specific optimizations:
+- `SEMANTIC_SIMILARITY`
+- `CLASSIFICATION`
+- `CLUSTERING`
+- `RETRIEVAL_DOCUMENT`
+- `RETRIEVAL_QUERY`
+- `QUESTION_ANSWERING`
+- `FACT_VERIFICATION`
+
+Example with task type:
+```python
+embedder={
+    "provider": "gemini",
+    "config": {
+        "model": "text-embedding-004",
+        "task_type": "RETRIEVAL_DOCUMENT"
+    }
+}
+```
+
+## Complete Example
+
+```python
+import os
+from praisonaiagents import Agent, Task, PraisonAIAgents
+
+# Ensure Google API key is set
+os.environ["GOOGLE_API_KEY"] = "your-api-key"
+
+# Create agents
+researcher = Agent(
+    name="Researcher",
+    role="Information Researcher",
+    goal="Store information with semantic understanding",
+    llm="gpt-4o-mini"
+)
+
+# Create task
+task = Task(
+    description="Research and store information about AI advancements",
+    expected_output="Confirmation of stored information",
+    agent=researcher
+)
+
+# Initialize with Gemini embeddings
+agents = PraisonAIAgents(
+    agents=[researcher],
+    tasks=[task],
+    memory=True,
+    embedder={
+        "provider": "gemini",
+        "config": {
+            "model": "text-embedding-004"
+        }
+    }
+)
+
+# Run the agents
+agents.start()
+```
+
+## Backward Compatibility
+
+The implementation maintains full backward compatibility:
+
+1. **No embedder config**: Uses default OpenAI `text-embedding-3-small`
+2. **Existing configs**: Continue to work without modification
+3. **Other providers**: Supports any embedding model available through LiteLLM
+
+## Memory Configuration with Mem0
+
+When using Mem0 as the memory provider, the embedder configuration is passed through:
+
+```python
+memory_config = {
+    "provider": "mem0",
+    "config": {
+        "api_key": "your-mem0-key",
+        "embedder": {
+            "provider": "gemini",
+            "config": {
+                "model": "text-embedding-004"
+            }
+        }
+    }
+}
+```
+
+## Troubleshooting
+
+1. **API Key Error**: Ensure `GOOGLE_API_KEY` is set in your environment
+2. **Model Not Found**: Verify the model name is correct
+3. **LiteLLM Error**: Ensure litellm is installed and up to date
+4. **Embedding Size Mismatch**: When switching models, you may need to clear the vector database as different models produce different embedding dimensions

-✅ Existing workflows continue to work unchanged
-✅ Context building falls back to original behavior when no feedback
-✅ No breaking changes to public APIs
-
-Agent 3: Feature Implementation Validator
-----------------------------------------
-✅ Captures validation failure reason correctly
-✅ Includes rejected output from failed attempt
-✅ Provides clear feedback message to retry task
-✅ Automatically clears feedback after use
-
-Agent 4: Security and Performance Auditor
-----------------------------------------
-✅ No security vulnerabilities introduced
-✅ No sensitive data exposure risks
-✅ Minimal performance impact (simple dict operations)
-✅ Memory efficient - feedback cleared after use
-
-Agent 5: Test Coverage Analyst
-------------------------------
-✅ Unit tests cover all new functionality
-✅ Tests verify backward compatibility
-✅ Integration examples provided
-✅ Edge cases handled (no feedback, empty feedback)
-
-CONSENSUS: Implementation is APPROVED
-====================================
-
-The implementation successfully addresses the issue:
