+# 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.
