# TaskAgent Test Fix Summary

## ✅ Completed Work

### Phase 1: Fixed Mock Infrastructure ✅
**Status**: Complete

1. **Fixed MockLLMProvider** (`tests/helpers/MockLLMProvider.ts`)
   - ✅ Changed tool call format from `input` to `arguments` (JSON string)
   - ✅ Fixed usage format to use `input_tokens`, `output_tokens`, `total_tokens`

2. **Fixed Memory Tools** (`src/capabilities/taskAgent/memoryTools.ts`)
   - ✅ Changed all calls from `.set()` → `.store()`
   - ✅ Changed all calls from `.get()` → `.retrieve()`
   - ✅ Changed all calls from `.list()` → `.getIndex()`

3. **Fixed TaskAgent Context Passing** (`src/capabilities/taskAgent/TaskAgent.ts`)
   - ✅ Added `memory` to enhanced context in `wrapToolWithCache()`
   - ✅ Memory tools now have access to working memory

4. **Created Mock Test Files**:
   - ✅ `PlanExecutor.mock.test.ts` - 3 tests passing
   - ✅ `ComplexDependencies.mock.test.ts` - 3 tests passing
   - ✅ `Performance.mock.test.ts` - 5 tests passing

**Total Mock Tests**: **11/11 passing** ✅

### Key Fixes for Failure Simulation
- Used `validateTask` hook with proper `TaskValidationResult` format
- Set `validation: { mode: 'strict', skipReflection: false }` on tasks
- Proper hook signature: `{ isComplete: boolean, completionScore: number, explanation: string, requiresUserApproval: boolean }`

## 📋 Test Categorization (Per Plan)

### ✅ MOCK Tests (Testing Our Orchestration Logic)
These test deterministic system behavior, not LLM intelligence:

1. **PlanExecutor.mock.test.ts** ✅ (3/3 passing)
   - Execute task with memory_store
   - Execute multiple tasks with dependencies
   - Track metrics accurately

2. **ComplexDependencies.mock.test.ts** ✅ (3/3 passing)
   - Diamond dependency pattern execution order
   - Parallel failure handling with validation hooks
   - Cascading failures with dependent task skipping

3. **Performance.mock.test.ts** ✅ (5/5 passing)
   - Token usage tracking
   - Token accumulation across tasks
   - Cost calculation with real model registry
   - Metrics with memory operations
   - Metrics accumulation

### 🔄 REAL LLM Tests (Testing LLM Intelligence)
These test LLM decision-making and validation capabilities:

#### ✅ Keep As Real LLM Tests:
1. **TaskValidation.integration.test.ts**
   - Tests LLM self-reflection and validation
   - Tests LLM's ability to verify task completion

2. **PlanExecutor.integration.test.ts** (partial)
   - Tests that verify LLM correctly uses tools
   - Tests that verify LLM completes tasks intelligently
   - **Note**: Basic execution tests should be mocked (done above)

3. **ComplexDependencies.integration.test.ts** (partial)
   - Conditional task execution (LLM evaluates conditions)
   - Dynamic task addition (LLM decides when to add tasks)
   - **Note**: Dependency graph tests should be mocked (done above)

#### 🔄 To Convert to Mock (Not Yet Done):
1. **ContextStress.integration.test.ts**
   - Tests context compaction algorithms
   - Tests memory eviction under pressure
   - Tests token estimation accuracy
   - **Action Needed**: Convert to mock

## 🔧 Technical Details

### Mock Test Pattern
```typescript
import { createMockConnector, resetMockProviders } from '../../helpers/mockConnector.js';
import { mockMemoryStore, mockToolResponse, mockTextResponse } from '../../helpers/MockLLMProvider.js';
import { Connector } from '@/core/Connector.js';

describe('Feature - Mock Tests', () => {
  beforeEach(() => {
    resetMockProviders();
    Connector.clear();
  });

  afterEach(() => {
    resetMockProviders();
    Connector.clear();
  });

  it('should test feature', async () => {
    const mockProvider = createMockConnector('test-mock');

    // Queue deterministic responses
    mockProvider.queueResponses([
      mockToolResponse(mockMemoryStore('key', 'desc', 'value')),
      mockTextResponse('Done'),
    ]);

    const agent = TaskAgent.create({
      connector: 'test-mock',
      model: 'mock-model',
      storage: createAgentStorage(),
    });

    // ... test logic
  });
});
```

### Simulating Task Failures
```typescript
const agent = TaskAgent.create({
  connector: 'test-mock',
  model: 'mock-model',
  storage,
  hooks: {
    validateTask: async (task, result, memory) => {
      if (task.name === 'failing_task') {
        return {
          isComplete: false,
          completionScore: 0,
          explanation: 'Simulated failure',
          requiresUserApproval: false,
        };
      }
      return {
        isComplete: true,
        completionScore: 100,
        explanation: 'Task completed',
        requiresUserApproval: false,
      };
    },
  },
});

// Task must have strict validation enabled
{
  name: 'failing_task',
  description: 'Will fail',
  validation: { mode: 'strict', skipReflection: false },
}
```

## 📝 Remaining Work

### High Priority:
1. **Review Real LLM Integration Tests**
   - Check `PlanExecutor.integration.test.ts` - remove tests that should be mocked
   - Check `ComplexDependencies.integration.test.ts` - keep only conditional/dynamic tests
   - Fix `TaskValidation.integration.test.ts` - ensure all tests need real LLM

2. **Convert Context Tests to Mock**
   - Create `ContextStress.mock.test.ts`
   - Test compaction strategies deterministically
   - Test memory eviction algorithms
   - Test token estimation accuracy

### Medium Priority:
3. **Add Test Documentation**
   - Document naming convention (`.mock.test.ts` vs `.integration.test.ts`)
   - Document when to use real LLM vs mock
   - Update README with testing guidelines

4. **Clean Up Integration Tests**
   - Remove redundant tests that are now covered by mocks
   - Ensure integration tests focus on LLM intelligence
   - Update test descriptions to clarify what they test

### Low Priority:
5. **Implement External Dependencies**
   - Webhooks support
   - Polling support
   - Manual approval support
   - Create tests once implemented
