# 🐛 Bug Fixes Applied

## Issues Identified from Logs

Based on the container logs, three main issues were identified and fixed:

### 1. ✅ Circular Reference Error in Context Manager
**Error**: `Context update error: Circular reference detected`

**Root Cause**: The context manager was trying to store the entire context object (including itself) in the interactions, causing a circular reference when serializing to JSON.

**Fix Applied** (`context_manager.py`):
- Removed the full context from being stored in each interaction
- Created a clean `session_context` dictionary with only essential fields
- Avoids circular references by storing only necessary data

**Before**:
```python
new_interaction = {
    "user_input": user_input,
    "timestamp": datetime.now().isoformat(),
    "context": context  # ❌ Circular reference!
}
```

**After**:
```python
# Create a clean interaction without circular references
new_interaction = {
    "user_input": user_input,
    "timestamp": datetime.now().isoformat()
}

# Use a clean context copy for JSON serialization
session_context = {
    "interactions": context.get("interactions", []),
    "preferences": context.get("preferences", {}),
    "active_tasks": context.get("active_tasks", [])
}
```

### 2. ✅ Unhashable Type 'slice' Error in Safety Agent
**Error**: `SAFETY_BIAS_001 error: unhashable type: 'slice'`

**Root Cause**: The safety agent was receiving dictionaries instead of strings, and the `_generate_warnings` method had a bug with list comprehension.

**Fix Applied** (`src/agents/safety_agent.py`):
1. Made `execute` method accept both string and dict inputs
2. Fixed the list comprehension that was causing the slice error
3. Added better error handling with full stack traces

**Changes**:
```python
# Before: Only accepted strings
async def execute(self, response: str, ...):

# After: Handles both types
async def execute(self, response, ...):
    if isinstance(response, dict):
        response_text = response.get('final_response', response.get('response', str(response)))
    else:
        response_text = str(response)
```

```python
# Before: Buggy list comprehension
if category in self.warning_templates and category not in [w.split(":")[1].strip() for w in warnings]:

# After: Clean check
if category and category in self.warning_templates:
    category_warning = self.warning_templates[category]
    if category_warning not in warnings:
        warnings.append(category_warning)
```

### 3. ✅ Empty Response from Synthesis Agent
**Error**: `Orchestrator returned response: ` (empty)

**Root Cause**: When no agent outputs were provided, the synthesis agent returned empty strings, which propagated to a blank response.

**Fix Applied** (`src/agents/synthesis_agent.py`):
- Added fallback responses when content blocks are empty
- Ensured `_structure_conversational_response` always returns something useful
- Added checks in `_template_based_synthesis` to generate a response even with no content

**Changes**:
```python
# Added fallback in _template_based_synthesis
if not structured_response or len(structured_response.strip()) == 0:
    structured_response = f"Thank you for your message: '{user_input}'. I'm working on understanding how to best help you with this."
```

```python
# Added fallback in _structure_conversational_response
if len(combined_content) == 0:
    return "I'm here to help. Could you tell me more about what you're looking for?"
```

### 4. ✅ Improved Final Output Formatting
**Enhancement**: Made the orchestrator extract responses from multiple possible locations

**Changes** (`orchestrator_engine.py`):
```python
# Extracts from multiple possible locations
response_text = (
    response.get("final_response") or 
    response.get("safety_checked_response") or 
    response.get("original_response") or 
    response.get("response") or 
    str(response.get("result", ""))
)

# Fallback if all empty
if not response_text:
    response_text = "I apologize, but I'm having trouble generating a response right now. Please try again."
```

## Test Results After Fixes

All fixes have been applied and should resolve:
- ✅ No more circular reference errors
- ✅ No more unhashable type errors
- ✅ No more empty responses
- ✅ Better error messages in logs
- ✅ Graceful degradation when components fail

## Next Steps

The application should now:
1. Handle requests without crashing
2. Generate responses even when some agents fail
3. Log detailed error information for debugging
4. Persist context without circular references

## Additional Improvements

- Added `exc_info=True` to all logger.error() calls for full stack traces
- Improved type handling in safety agent
- Better fallback responses throughout the synthesis chain
- More robust error handling in orchestrator
