+ }); +}); +``` + +## Function Calling Best Practices for Providers + +### 1. Tool Schema Validation +```typescript +// Always validate tool schemas before sending to provider +private validateToolSchema(tool: FrameworkTool): boolean { + try { + const jsonSchema = this.zodToJsonSchema(tool.paramsSchema); + // Check for provider-specific limitations + if (this.providerName === 'openai' && !jsonSchema.additionalProperties) { + console.warn(`Tool ${tool.name}: OpenAI requires additionalProperties: false for strict mode`); + } + return true; + } catch (error) { + console.error(`Invalid tool schema for ${tool.name}:`, error); + return false; + } +} +``` + +### 2. Handling Provider Limitations +```typescript +// Different providers have different capabilities +class ProviderCapabilities { + supportsParallelToolCalls: boolean = true; + maxToolsPerRequest: number = 128; + supportsStreamingToolCalls: boolean = true; + requiresStrictMode: boolean = false; + + // OpenAI specific + static openai(): ProviderCapabilities { + return { + supportsParallelToolCalls: true, + maxToolsPerRequest: 128, + supportsStreamingToolCalls: true, + requiresStrictMode: false, + }; + } + + // Anthropic specific + static anthropic(): ProviderCapabilities { + return { + supportsParallelToolCalls: true, + maxToolsPerRequest: 64, + supportsStreamingToolCalls: true, + requiresStrictMode: true, + }; + } +} +``` + +### 3. Error Recovery in Tool Calling +```typescript +// Graceful degradation when tool calling fails +async chatWithToolFallback(options: ChatOptions): Promise { + try { + // Try with tools first + return await this.chatWithTools(options); + } catch (error) { + if (this.isToolCallingError(error)) { + // Fallback to regular chat without tools + console.warn('Tool calling failed, falling back to regular chat:', error); + return await this.chat({ + ...options, + tools: undefined, + messages: this.addToolUnavailableMessage(options.messages), + }); + } + throw error; + } +} +``` + +### 4. Token Optimization for Tools +```typescript +// Optimize token usage with tools +private optimizeToolsForTokens( + tools: FrameworkTool[], + availableTokens: number +): FrameworkTool[] { + // Estimate tokens for each tool definition + const toolsWithTokens = tools.map(tool => ({ + tool, + tokens: this.estimateToolTokens(tool), + })); + + // Sort by priority and select within token budget + toolsWithTokens.sort((a, b) => b.tool.priority - a.tool.priority); + + const selected: FrameworkTool[] = []; + let totalTokens = 0; + + for (const { tool, tokens } of toolsWithTokens) { + if (totalTokens + tokens <= availableTokens) { + selected.push(tool); + totalTokens += tokens; + } + } + + return selected; +} +``` + +### 5. Testing Tool Calling +```typescript +// Comprehensive testing for tool calling +describe('Provider Tool Calling', () => { + it('should handle single tool call', async () => { + const provider = new TestProvider(); + const response = await provider.chat({ + messages: [{ role: 'user', content: 'What is 2+2?' }], + tools: [calculatorTool], + }); + + expect(response.toolCalls).toHaveLength(1); + expect(response.toolCalls[0].name).toBe('calculator'); + }); + + it('should handle parallel tool calls', async () => { + // Test multiple tools called in one response + }); + + it('should stream tool calls correctly', async () => { + // Test streaming with tool call deltas + }); + + it('should handle tool call errors gracefully', async () => { + // Test error scenarios + }); +}); +``` + +**Best Practices**: + +1. **Always study existing implementations first** - Understand the patterns +2. **Maintain strict type safety** - No `any` types in provider code +3. **Handle all error cases** - Network, auth, rate limits, etc. +4. **Test with real APIs** - Mock for unit tests, real for integration +5. **Document provider-specific features** - Help users understand differences +6. **Keep providers isolated** - No cross-provider dependencies +7. **Validate tool schemas** - Ensure compatibility with provider requirements +8. **Optimize for tokens** - Tools consume context, manage wisely +9. **Support graceful degradation** - Fall back when tool calling fails +10. **Test streaming thoroughly** - Tool call streaming is complex + +**Common Pitfalls to Avoid**: +- Leaking provider-specific types to core framework +- Incomplete streaming implementation +- Inaccurate token counting +- Missing error handling for edge cases +- Hardcoded configuration values +- Blocking operations in async code + +Remember: Your implementations enable MiniAgent to work with any LLM provider while maintaining a consistent, type-safe interface.

Module Boundary Identification +- Clear module boundaries enable parallel execution +- Each agent should work on an isolated module +- Minimize inter-module dependencies +- Document dependencies in management-plan.md + +### 3. Minimal First +- Always question if a feature is necessary +- Prefer composition over inheritance +- Keep the API surface small + +### 2. Type Safety +- Every public API must be strongly typed +- Use TypeScript's advanced features appropriately +- No `any` types in public interfaces + +### 3. Provider Agnostic +- Core should never depend on specific providers +- Providers should adapt to core, not vice versa +- Keep provider-specific logic isolated + +### 4. Example Driven +- Every feature needs a practical example +- Examples should be simple and focused +- Keep examples up-to-date with API changes + +### 5. Progressive Enhancement +- Start with the simplest implementation +- Add complexity only when proven necessary +- Document why complexity was added + +## Success Metrics + +A well-coordinated MiniAgent task has: +- ✅ Created dedicated Git branch for the task +- ✅ **Designed parallel execution plan** in management-plan.md +- ✅ **Maximized parallel agent utilization** where possible +- ✅ Maintains framework minimalism +- ✅ Full TypeScript type coverage +- ✅ Comprehensive test suite +- ✅ Updated examples +- ✅ Clear documentation +- ✅ No breaking changes (or migration guide if necessary) +- ✅ All changes committed to Git with proper tags +- ✅ Agent-context documentation committed +- ✅ Branch ready for merge (via PR or direct merge) +- ✅ **Time saved through parallelization documented** + +## Error Handling + +If a sub-agent proposes non-minimal solutions: +1.

Interface-Driven Design +The framework uses TypeScript interfaces (`src/interfaces.ts`) to define contracts between components. Every major component (Agent, Chat, Tool, ToolScheduler) has an interface that implementations must satisfy. This allows for: +- Multiple provider implementations (Gemini, OpenAI) +- Easy testing through mocks +- Clear separation of concerns + +### 2. Event-Driven Architecture +The agent operates through an event system (`src/agentEvent.ts`) that emits events during processing: +- User messages, assistant responses, tool calls +- Token usage updates +- Turn completion events +- Error events + +The main processing loop in `BaseAgent.process()` is an async generator that yields events, allowing consumers to handle them in real-time. + +### 3. Tool Execution Pipeline +Tools are executed through a sophisticated pipeline managed by `CoreToolScheduler`: +- **Validation**: Tools validate parameters before execution +- **Confirmation**: Optional user confirmation for destructive operations +- **Execution**: Async execution with abort signal support +- **Output Streaming**: Real-time output updates during execution +- **Result Handling**: Structured results returned to the LLM + +### Key Components + +**BaseAgent** (`src/baseAgent.ts`): +- Core orchestrator implementing the agent loop +- Manages conversation history and token limits +- Coordinates between Chat provider and Tool scheduler +- Implements streaming response handling + +**StandardAgent** (`src/standardAgent.ts`): +- Session management layer built on BaseAgent +- Handles multiple concurrent conversations +- Provides simplified API for common use cases + +**Chat Providers** (`src/chat/`): +- GeminiChat: Google Gemini integration with native tool support +- OpenAIChat: OpenAI integration with response caching +- Both implement streaming and tool calling + +**Tool System** (`src/baseTool.ts`): +- BaseTool: Abstract class for tool implementations +- SimpleTool: Functional tool creation helper +- Tools define schemas, validation, and async execution + +**CoreToolScheduler** (`src/coreToolScheduler.ts`): +- Manages parallel tool execution +- Handles confirmation workflows +- Provides real-time status updates via callbacks + +### Important Patterns + +1. **Streaming-First**: All chat providers use streaming responses.

Test Structure + +```typescript +// Consistent test organization +describe('ComponentName', () => { + describe('Feature Category', () => { + let component: ComponentType; + + beforeEach(() => { + component = new ComponentType(mockConfig); + }); + + it('should handle normal case', async () => { + // Arrange, Act, Assert pattern + }); + + it('should handle error case', async () => { + // Error scenarios + }); + + it('should handle edge case', async () => { + // Edge cases and boundaries + }); + }); +}); +``` + +### 2. Mock Management + +```typescript +// Centralized mock factory +export class MockFactory { + static createAgent(overrides?: Partial): BaseAgent { + const config = { ...defaultConfig, ...overrides }; + return new TestAgent(config, MockFactory.createChat(), MockFactory.createToolScheduler()); + } + + static createChat(): IChat { + return new MockChatProvider(); + } + + static createToolScheduler(): IToolScheduler { + return new MockToolScheduler(); + } +} +``` + +### 3. Async Testing Patterns + +```typescript +// Async generator testing +async function collectEvents(generator: AsyncGenerator): Promise { + const events: T[] = []; + for await (const event of generator) { + events.push(event); + } + return events; +} + +// Stream testing with timeout +async function collectEventsWithTimeout( + generator: AsyncGenerator, + timeoutMs: number = 1000 +): Promise { + const events: T[] = []; + const timeout = setTimeout(() => controller.abort(), timeoutMs); + + try { + for await (const event of generator) { + events.push(event); + } + } finally { + clearTimeout(timeout); + } + + return events; +} +``` + +## Coverage Targets by Component + +| Component | Lines | Branches | Functions | Statements | Priority | +|-----------|-------|----------|-----------|------------|----------| +| BaseAgent | 95% | 90% | 95% | 95% | Critical | +| StandardAgent | 90% | 85% | 90% | 90% | High | +| GeminiChat | 85% | 80% | 85% | 85% | High | +| OpenAIChat | 85% | 80% | 85% | 85% | High | +| BaseTool | 90% | 85% | 90% | 90% | High | +| CoreToolScheduler | 90% | 85% | 90% | 90% | Critical | +| TokenTracker | 95% | 90% | 95% | 95% | Medium | +| Logger | 85% | 80% | 85% | 85% | Low | +| Interfaces | 100% | N/A | 100% | 100% | Critical | + +**Overall Target**: 85% lines, 80% branches, 85% functions, 85% statements + +## Implementation Phases + +### Phase 1: Fix Current Issues (Priority: Critical) +1. **Fix BaseTool Tests**: Add missing helper methods or update test expectations +2. **Fix GeminiChat Import**: Resolve missing file import issue +3. **Validate Test Setup**: Ensure vitest configuration is correct + +### Phase 2: Core Component Tests (Priority: High) +1. **BaseAgent Test Suite**: Complete event system, streaming, tool integration +2. **StandardAgent Test Suite**: Session management, multi-session scenarios +3. **Chat Provider Tests**: Provider-specific functionality, error handling + +### Phase 3: Integration & E2E (Priority: Medium) +1. **Integration Tests**: Cross-component interaction, real API calls (with mocks) +2. **E2E Scenarios**: Common user workflows, performance benchmarks +3. **Documentation**: Update testing guidelines, examples + +## Quality Metrics + +### Test Quality Indicators +- **Test Coverage**: 85%+ overall, 90%+ for critical components +- **Test Performance**: < 10 seconds for full test suite +- **Test Reliability**: < 1% flaky test rate +- **Test Maintainability**: Clear structure, minimal duplication + +### Monitoring and Reporting +- **CI Integration**: Automated coverage reporting +- **Coverage Trending**: Track coverage changes over time +- **Performance Monitoring**: Detect performance regressions +- **Quality Gates**: Block deployments below coverage thresholds + +## Risk Assessment + +### High Risk Areas +1. **Async/Stream Testing**: Complex generator testing, timing issues +2. **Provider Integration**: External API dependencies, rate limits +3. **Tool Execution**: Parallel execution, resource contention +4. **Event System**: Race conditions, event ordering + +### Mitigation Strategies +1. **Deterministic Testing**: Fixed seeds, controlled timing +2. **Mock Isolation**: Comprehensive mocking strategy +3. **Retry Logic**: Flaky test detection and retry +4. **Resource Management**: Proper cleanup, timeout handling + +## Recommendations + +### Immediate Actions +1. **Fix Existing Tests**: Address 13 failing baseTool tests +2. **Implement Missing Tests**: BaseAgent and StandardAgent test suites +3. **Standardize Mocking**: Create consistent mock patterns +4. **Setup CI Coverage**: Automated coverage reporting + +### Long-term Improvements +1. **Property-Based Testing**: Use property-based testing for edge cases +2. **Mutation Testing**: Validate test effectiveness +3. **Performance Regression**: Continuous performance monitoring +4. **Visual Testing**: UI component testing (if applicable) + +## Conclusion + +This test architecture provides a comprehensive foundation for achieving 85%+ coverage while maintaining the MiniAgent framework's minimal philosophy.
