# DOC-01: Complete API Reference

**Priority**: P2 - Medium  
**Estimated Effort**: 16-24 hours  
**Impact**: HIGH - Improves developer experience  
**Category**: Documentation

## Problem

API Reference 85% incomplete:
- Only 2 of 23 modules documented  
- Hard for users to understand programmatic usage  
- No API docs for new features

## Solution

Add comprehensive docstrings to all public APIs.

## Implementation

### Module: AgentOrchestrator

```python
class AgentOrchestrator:
    """
    Central orchestrator for multi-agent task execution.

    The AgentOrchestrator manages the lifecycle of agent executions,
    including initialization, execution, error handling, and result
    aggregation.

    Attributes:
        config_path (str): Path to configuration file
        enable_cache (bool): Whether response caching is enabled
        enable_tracking (bool): Whether performance tracking is enabled

    Example:
        >>> orchestrator = AgentOrchestrator()
        >>> result = orchestrator.run_agent("code-reviewer", task="Review auth.py")
        >>> if result.success:
        ...     print(result.output)

    See Also:
        - :class:`HybridOrchestrator`: For cost-optimized model selection
        - :class:`AsyncOrchestrator`: For concurrent execution

    .. versionadded:: 2.0.0
    """

    def run_agent(
        self,
        agent_name: str,
        task: str,
        model: Optional[str] = None,
        **kwargs
    ) -> AgentResult:
        """
        Execute a single agent on a task.

        Args:
            agent_name: Name of the agent to execute
            task: Task description
            model: Optional model override (haiku/sonnet/opus)
            **kwargs: Additional parameters

        Returns:
            AgentResult: Execution result with output and metadata

        Raises:
            ValueError: If agent_name is invalid
            RuntimeError: If execution fails

        Example:
            >>> result = orchestrator.run_agent(
            ...     "code-reviewer",
            ...     task="Review authentication code"
            ... )
            >>> assert result.success

        Note:
            Results are cached by default. Identical tasks return
            cached responses for 90 days.

        .. versionchanged:: 2.2.0
           Added auto model selection support
        """
        pass
