# Helper Agents Integration Checklist

This checklist ensures the helper agents system is ready for integration into
the main Lace codebase.

## ✅ Core Implementation

### Type System Consistency

- [x] **ToolCall Interface**: All providers use consistent `ToolCall` interface
      with `arguments` property
- [x] **Provider Response**: `ProviderResponse.toolCalls` uses standard
      `ToolCall[]` type
- [x] **Agent Interface**: `AgentMessageResult.toolCalls` uses standard
      `ToolCall[]` type
- [x] **Format Converters**: All provider-specific format conversions properly
      map to/from standard format
- [x] **TypeScript Compilation**: Clean compilation with strict mode enabled
- [x] **No Type Duplication**: No remnants of old `ProviderToolCall` or other
      duplicate interfaces

### Helper System Components

- [x] **BaseHelper**: Abstract base class with multi-turn execution logic
- [x] **InfrastructureHelper**: System-level tasks with explicit tool
      whitelisting
- [x] **SessionHelper**: Agent sub-tasks with context inheritance
- [x] **HelperFactory**: Type-safe creation methods with proper validation
- [x] **HelperRegistry**: Centralized lifecycle management with tracking
- [x] **Helper Types**: Comprehensive `HelperResult` interface with token
      tracking

### Security Models

- [x] **Infrastructure Security**: Explicit tool whitelisting prevents
      unauthorized tool usage
- [x] **Session Security**: Inherits parent agent approval policies and session
      context
- [x] **Context Isolation**: No agent property in infrastructure helper context
- [x] **Working Directory**: Proper working directory inheritance and overrides
- [x] **Abort Signals**: Cancellation support throughout execution chain

## ✅ Quality Assurance

### Testing Coverage

- [x] **Unit Tests**: 50+ tests covering all helper components
- [x] **Integration Tests**: Real-world usage patterns and cross-component
      interactions
- [x] **Factory Tests**: Type-safe creation with validation edge cases
- [x] **Registry Tests**: Lifecycle management and concurrent helper tracking
- [x] **Multi-turn Tests**: Complex LLM conversations with tool usage
- [x] **Error Handling**: Graceful degradation and proper error propagation

### Code Quality

- [x] **Linting**: Clean ESLint results with no disabled rules
- [x] **TypeScript**: Strict mode compliance with no any types
- [x] **Architecture**: Clear separation of concerns and single responsibility
- [x] **Naming**: Consistent naming conventions following project standards
- [x] **Documentation**: ABOUTME comments on all files explaining purpose

### Performance

- [x] **Model Tiers**: Proper fast/smart model selection based on task
      complexity
- [x] **Token Tracking**: Comprehensive usage monitoring and reporting
- [x] **Resource Management**: Registry provides lifecycle management
- [x] **Concurrent Limits**: Framework for managing multiple helper instances
- [x] **Memory Efficiency**: Stateless design with proper cleanup

## ✅ Integration Compatibility

### Provider System

- [x] **Approval Workflow**: Integrates with existing approval system
- [x] **Context Passing**: Proper working directory and signal propagation
- [x] **Result Format**: Standard ToolResult interface compatibility

### Agent System

- [x] **Agent Context**: Session helpers inherit from parent agent properly
- [x] **Tool Inheritance**: Available tools correctly inherited from parent
- [x] **Working Directory**: Session working directory properly inherited
- [x] **Approval Policies**: Respects parent session approval configuration
- [x] **Thread Safety**: No shared state between helper instances

## ✅ Production Readiness

### Configuration

- [x] **Model Mapping**: Proper fast/smart model tier configuration
- [x] **Provider Instances**: Works with configured provider instances
- [x] **Environment Variables**: No hardcoded configuration values
- [x] **Graceful Degradation**: Handles missing configuration appropriately

### Error Handling

- [x] **Tool Failures**: Individual tool failures don't break execution
- [x] **Provider Errors**: Proper error propagation and recovery
- [x] **Timeout Handling**: Abort signal support throughout stack
- [x] **Resource Limits**: Framework for concurrent helper limits
- [x] **Debugging**: Comprehensive logging with structured metadata

### Monitoring
