## Acceptance Criteria Verification

### Pattern Consistency ✅
**Requirement**: Consistent pattern across all 10 agents

**Evidence**: All agents follow identical pattern:
```python
def __init__(
    self,
    # ... existing parameters ...
    tool_registry: Optional["ToolRegistry"] = None,  # NEW
    mcp_servers: Optional[List[Dict]] = None,       # NEW
):
    super().__init__(
        # ... existing parameters ...
        tool_registry=tool_registry,  # Pass to BaseAgent
        mcp_servers=mcp_servers,       # Pass to BaseAgent
    )
```

**Verification**: Pattern verified in all 10 agent files

### Backward Compatibility ✅
**Requirement**: 100% backward compatible (optional parameters)

**Evidence**:
- All parameters default to `None`
- All existing tests pass (259 regression tests)
- Agents work without tool_registry parameter
- No breaking changes to existing APIs

**Test Results**:
- Consensus: 89/89 passing
- Debate: 100/100 passing
- Supervisor Worker: 70/70 passing
- Backward compatibility: 3/3 comprehensive tests passing

### Docstring Documentation ✅
**Requirement**: Comprehensive documentation for new parameters

**Evidence**: All 10 agents have complete docstrings:
- Parameter descriptions for `tool_registry`
- Parameter descriptions for `mcp_servers`
- Usage examples in module docstrings
- Integration with BaseAgent documented

**Verification**: Docstrings verified in all agent files

### Parameter Passing ✅
**Requirement**: Proper parameter passing to BaseAgent

**Evidence**: All agents correctly pass parameters to `super().__init__()`:
- `tool_registry=tool_registry`
- `mcp_servers=mcp_servers`

**Verification**: Parameter passing verified in all 10 agent `__init__()` methods
