+            You are a helpful GitHub issue assistant. Your task is to analyze and help with GitHub issues.
+            
+            **Issue Details:**
+            - Issue Number: #${ISSUE_NUMBER}
+            - Repository: ${REPOSITORY}

+            **Additional Instructions:** ${ADDITIONAL_INSTRUCTIONS}
+            
+            **CRITICAL: When making code modifications, follow this EXACT workflow:**
+            
+            **STEP 1: Analyze the Issue**
+            - Use: `gh issue view ${ISSUE_NUMBER} --json title,body,labels,assignees`
+            - Analyze issue content thoroughly
+            - Search codebase for related files using `glob`, `search_file_content`, `list_directory`
+            
+            **STEP 2: If Code Changes Are Needed**
+            Create a new branch with 'gemini/' prefix:
+            - Use: `git checkout -b gemini/issue-${ISSUE_NUMBER}-description`
+            - Example: `git checkout -b gemini/issue-123-fix-sequential-tools`
+            
+            **STEP 3: Make Code Modifications**
+            - Use `read_file` to examine existing code
+            - Use `write_file` or `replace` to make changes
+            - Use `search_file_content` to find related code
+            - Make focused, targeted changes to fix the issue
+            
+            **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**
+            - Use: `git add .` (or specific files)
+            - Use: `git commit -m "Gemini: [Issue #${ISSUE_NUMBER}] Brief description of fix"`
+            - Use: `git push -u origin gemini/issue-${ISSUE_NUMBER}-description`
+            
+            **STEP 6: Create Pull Request**
+            - Use: `gh pr create --title "Fix #${ISSUE_NUMBER}: Issue description" --body "Fixes #${ISSUE_NUMBER}\n\nSummary of changes:\n- Change 1\n- Change 2" --head gemini/issue-${ISSUE_NUMBER}-description --base main`
+            - This will return a PR URL like: https://github.com/repo/pull/123
+            
+            **STEP 7: Comment on Issue with Results**
+            Use: `gh issue comment ${ISSUE_NUMBER} -b "MESSAGE"`

+            Hi! I've analyzed and fixed this issue.
+            
+            **Problem:** Sequential tool calling was getting stuck after first tool call.
+            
+            **Solution:** Added proper prompt handling after each tool call in the Ollama model integration.
+            
+            **Changes Made:**
+            - Modified `src/praisonai-agents/ollama-sequential.py`
+            - Added continuation prompts for multi-step tool execution
+            
+            **Pull Request:** https://github.com/MervinPraison/PraisonAI/pull/856
+

+          prompt: |
+            You are an expert code reviewer and AI assistant for Pull Requests. You can review code AND make modifications to improve the PR.
+
+            **PR Details:**
+            - PR Number: #$PR_NUMBER
+            - Repository: $REPOSITORY
+            - Additional Instructions: $ADDITIONAL_INSTRUCTIONS
+
+            **CRITICAL: When making code modifications, follow this EXACT workflow:**
+
+            **STEP 1: Analyze the PR**
+            - Use: `echo "$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
+            - Check for common issues: potential bugs, security vulnerabilities, performance bottlenecks
+            - Verify error handling and edge cases
+            - Look for code style and best practices
+            - Comment on architecture and design decisions if significant
+            - Be constructive and specific in feedback
+            - Highlight both issues and positive aspects
+            - Suggest improvements with examples when possible
+            
+            Review Areas:
+            - **Security**: Authentication, authorization, input validation, data sanitization
+            - **Performance**: Algorithms, database queries, caching, resource usage
+            - **Reliability**: Error handling, logging, testing coverage, edge cases
+            - **Maintainability**: Code structure, documentation, naming conventions
+            - **Functionality**: Logic correctness, requirements fulfillment
+

+# Ollama Handling in LLM.py
+
+The `ollama_handled` flag is used in `llm.py` (not in `agent.py`) to track whether special Ollama model handling has been applied for tool results. Here's what I found:
+
+## Where it's used in llm.py:
+- **Line 863**: `ollama_handled = False` - initialized at the beginning of the tool execution loop
+- **Line 864**: Special handling logic via `_handle_ollama_model()` method
+- **Line 907**: `ollama_handled = True` - set when Ollama special handling is applied
+- **Line 928 & 959**: Checks `if not ollama_handled` to avoid duplicate processing
+
+## Why it's needed:
+The flag prevents duplicate processing when Ollama models require special handling. Some Ollama models return only the tool call JSON without processing the results, requiring a follow-up prompt to get the final answer. The `ollama_handled` flag ensures this special handling happens only once.
+
+## Does this contradict the requirement?
+**No, it doesn't.** The issue states:
+
+> "ollama/xxxx model is already handled via llm.py via litellm, so no special condition or handling required for ollama inside agent.py"
+
+✅ **Current implementation is correct:**
+
+- `agent.py` has NO ollama-specific conditions (only one documentation mention as an example)
+- All ollama handling is contained within `llm.py` as intended
+- The `ollama_handled` flag is an internal implementation detail within `llm.py`
+
+The codebase already follows the desired pattern where ollama models are handled through the generic LLM interface via litellm without special conditions in agent.py.

+# Tool Call Fix Documentation
+
+## Issue
+Agents using Gemini models (`gemini/gemini-1.5-flash-8b`) were not calling provided tools, instead responding with "I do not have access to the internet" when tasked with searching.
+
+## Root Cause
+The Gemini model through LiteLLM was not being properly instructed to use the available tools. The system prompt didn't mention the tools, and the tool_choice parameter wasn't being set. Additionally, async agents were not passing the correct tools to the system prompt generation.
+
+## Fix Applied (Updated)
+
+### 1. Enhanced System Prompt (agent.py) - IMPROVED
+A new `_build_system_prompt` method was created to centralize system prompt generation with tool information. This ensures both sync and async agents get the same enhanced prompt:
+
+```python
+# New _build_system_prompt method with enhanced error handling and MCP tool support
+def _build_system_prompt(self, tools=None):
+    """Build the system prompt with tool information."""
+    if not self.use_system_prompt:
+        return None
+        
+    system_prompt = f"""{self.backstory}\n
+Your Role: {self.role}\n
+Your Goal: {self.goal}"""
+    
+    # Use provided tools or fall back to self.tools
+    tools_to_use = tools if tools is not None else self.tools
+    if tools_to_use:
+    tool_names = []
+    for tool in self.tools:
+        try:
+            if callable(tool) and hasattr(tool, '__name__'):
+                tool_names.append(tool.__name__)
+            elif isinstance(tool, dict) and isinstance(tool.get('function'), dict) and 'name' in tool['function']:
+                tool_names.append(tool['function']['name'])
+            elif isinstance(tool, str):
+                tool_names.append(tool)
+            elif hasattr(tool, "to_openai_tool"):
+                # Handle MCP tools
+                openai_tools = tool.to_openai_tool()
+                if isinstance(openai_tools, list):
+                    for t in openai_tools:
+                        if isinstance(t, dict) and 'function' in t and 'name' in t['function']:
+                            tool_names.append(t['function']['name'])
+                elif isinstance(openai_tools, dict) and 'function' in openai_tools:
+                    tool_names.append(openai_tools['function']['name'])
+        except (AttributeError, KeyError, TypeError) as e:
+            logging.warning(f"Could not extract tool name from {tool}: {e}")
+            continue
+    
+    if tool_names:
+        system_prompt += f"\n\nYou have access to the following tools: {', '.join(tool_names)}. Use these tools when appropriate to help complete your tasks. Always use tools when they can help provide accurate information or perform actions."
+```
+
+### 2. Tool Choice Parameter (llm.py) - IMPROVED
+For Gemini models, we now set `tool_choice='auto'` with better model detection and support checking:
+
+```python
+# In _build_completion_params method with enhanced model detection
+if 'tools' in params and params['tools'] and 'tool_choice' not in params:
+    # More comprehensive Gemini model detection
+    if any(prefix in self.model.lower() for prefix in ['gemini', 'gemini/', 'google/gemini']):
+        try:
+            import litellm
+            # Check if model supports function calling before setting tool_choice
+            if litellm.supports_function_calling(model=self.model):
+                params['tool_choice'] = 'auto'
+        except Exception as e:
+            # If check fails, still set tool_choice for known Gemini models
+            logging.debug(f"Could not verify function calling support: {e}. Setting tool_choice anyway.")
+            params['tool_choice'] = 'auto'
+```
+
+### 3. Async Agent Fix (agent.py) - NEW
+Fixed async agents to correctly pass tools for system prompt generation:
+
+```python
+# In sync chat method:
+agent_tools=[t.__name__ if hasattr(t, '__name__') else str(t) for t in (tools if tools is not None else self.tools)]
+
+# Fixed in async achat method (was always using self.tools):
+agent_tools=[t.__name__ if hasattr(t, '__name__') else str(t) for t in (tools if tools is not None else self.tools)]
+
+# Both sync and async now use enhanced system prompt:
+system_prompt=self._build_system_prompt(tools)
+```
+
+## Testing the Fix
+
+To test the fix, use the following code:
+
+```python
+import asyncio
+from praisonaiagents import Agent, Task, PraisonAIAgents
+
+# Define a simple tool
+async def search_tool(query: str) -> str:
+    """Search for information on the internet"""
+    return f"Search results for: {query}"
+
+# Create agent with Gemini model
+agent = Agent(
+    name="SearchAgent",
+    role="Information Researcher",
+    goal="Find accurate information using search tools",
+    backstory="Expert at finding and analyzing information",
+    tools=[search_tool],
+    llm={"model": "gemini/gemini-1.5-flash-8b"}
+)
+
+# Create task
+task = Task(
+    description="Search for information about AI breakthroughs in 2024",
+    expected_output="Summary of AI breakthroughs",
+    agent=agent
+)
+
+# Run
+async def test():
+    agents = PraisonAIAgents(agents=[agent], tasks=[task])
+    result = await agents.astart()
+    print(result)
+
+asyncio.run(test())
+```
+
+## Improvements Made to Original PR
+
+1. **Enhanced Error Handling**: Added try-catch blocks to prevent crashes from malformed tools
+2. **MCP Tool Support**: Now properly extracts names from tools with `to_openai_tool` method  
+3. **Better Model Detection**: More comprehensive Gemini model detection including variants like 'google/gemini'
+4. **Function Calling Support Check**: Uses litellm's `supports_function_calling` to verify model capabilities
+5. **Type Safety**: Added isinstance checks to prevent TypeErrors when accessing nested dictionaries
+6. **Async Agent Fix**: Fixed async agents to use the correct tools parameter instead of always using self.tools
+7. **Centralized System Prompt**: Created `_build_system_prompt` method to ensure consistency between sync and async paths
+
+## Backward Compatibility
+- The fix only adds to existing functionality without modifying core behavior
+- Tools continue to work exactly as before for all other models
+- The system prompt enhancement only occurs when tools are present
+- The tool_choice parameter is only added for Gemini models
+- All error handling is non-breaking with appropriate logging
+
+## Additional Recommendations
+
+If issues persist with specific models:
+
+1. **Explicit Tool Instructions in Task Description**:
+   ```python
+   task = Task(
+       description="Use the tavily_search tool to find information about AI breakthroughs",
+       # ... rest of task config
+   )
+   ```
+
+2. **Use OpenAI Models for Tool-Heavy Tasks**:
+   OpenAI models (gpt-4, gpt-4o) have better native tool calling support.
+
+3. **Debug Tool Registration**:
+   Enable debug logging to see tool registration:
+   ```python
+   import logging
+   logging.basicConfig(level=logging.DEBUG)
+   ```
+
+## Verification Steps
+
+1. Check that tools are properly formatted by the agent
+2. Verify the system prompt includes tool instructions
+3. Confirm tool_choice is set for Gemini models
+4. Monitor LLM responses for tool_calls in the response
+
+The fix ensures that Gemini models are properly instructed to use available tools, resolving the issue where agents would claim they don't have internet access despite having search tools available.
