AI Agent Integration Guide

Complete guide for integrating AI agents with TaskMaster’s autonomous TDD workflow system.

Overview

TaskMaster provides a complete TDD workflow orchestration system that enables AI agents to autonomously implement features following strict Test-Driven Development practices. The system manages workflow state, git operations, test validation, and progress tracking.

Key Features

TDD State Machine: Enforces RED → GREEN → COMMIT cycle
Git Integration: Automated branch creation, commits with metadata
Test Validation: Ensures RED phase has failures, GREEN phase passes
Progress Tracking: Subtask completion, attempt counting, error logging
State Persistence: Automatic workflow state management
Dual Interface: CLI commands and MCP tools for flexibility

Examples

Complete TDD Cycle Example

1. Start Workflow

$ tm autopilot start 7 --json

{
  "success": true,
  "taskId": "7",
  "branchName": "task-7",
  "tddPhase": "RED",
  "currentSubtask": {
    "id": "1",
    "title": "Implement start command",
    "status": "in-progress"
  },
  "nextAction": "generate_test"
}

2. Get Next Action

$ tm autopilot next --json

{
  "action": "generate_test",
  "actionDescription": "Write a failing test for the current subtask",
  "tddPhase": "RED",
  "currentSubtask": {
    "id": "1",
    "title": "Implement start command"
  }
}

3. Write Failing Test

AI Agent creates tests/start.test.ts:

import { describe, it, expect } from 'vitest';
import { StartCommand } from '../src/commands/start.js';

describe('StartCommand', () => {
  it('should initialize workflow and create branch', async () => {
    const command = new StartCommand();
    const result = await command.execute({ taskId: '7' });
    expect(result.success).toBe(true);
    expect(result.branchName).toBe('task-7');
  });
});

4. Run Tests (Should Fail)

$ npm test
# Output: 1 test failed (expected)

Parse output to JSON:

{
  "total": 1,
  "passed": 0,
  "failed": 1,
  "skipped": 0
}

5. Complete RED Phase

$ tm autopilot complete --results '{"total":1,"passed":0,"failed":1,"skipped":0}' --json

{
  "success": true,
  "message": "Completed RED phase",
  "previousPhase": "RED",
  "currentPhase": "GREEN",
  "nextAction": "implement_code"
}

6. Implement Code

AI Agent creates src/commands/start.ts:

export class StartCommand {
  async execute(options: { taskId: string }) {
    // Implementation that makes test pass
    return {
      success: true,
      branchName: `task-${options.taskId}`
    };
  }
}

7. Run Tests (Should Pass)

$ npm test
# Output: 1 test passed

Parse output:

{
  "total": 1,
  "passed": 1,
  "failed": 0,
  "skipped": 0
}

8. Complete GREEN Phase

$ tm autopilot complete --results '{"total":1,"passed":1,"failed":0,"skipped":0}' --json

{
  "success": true,
  "previousPhase": "GREEN",
  "currentPhase": "COMMIT",
  "nextAction": "commit_changes"
}

9. Commit Changes

$ tm autopilot commit --json

{
  "success": true,
  "commit": {
    "hash": "abc123",
    "message": "feat(autopilot): implement start command (Task 7.1)\n\n..."
  },
  "subtaskCompleted": "1",
  "currentSubtask": {
    "id": "2",
    "title": "Implement resume command"
  },
  "nextAction": "generate_test"
}

MCP Integration Example

// AI Agent using MCP tools

async function implementTask(taskId: string) {
  // Start workflow
  const start = await mcp.call('autopilot_start', {
    taskId,
    projectRoot: '/path/to/project'
  });

  console.log(`Started task ${start.taskId} on branch ${start.branchName}`);

  while (true) {
    // Get next action
    const next = await mcp.call('autopilot_next', {
      projectRoot: '/path/to/project'
    });

    console.log(`Next action: ${next.action}`);

    if (next.action === 'generate_test') {
      // AI generates test
      const testCode = await generateTest(next.currentSubtask);
      await writeFile(testCode);

      // Run tests
      const results = await runTests();

      // Complete RED phase
      await mcp.call('autopilot_complete_phase', {
        projectRoot: '/path/to/project',
        testResults: results
      });

    } else if (next.action === 'implement_code') {
      // AI generates implementation
      const implCode = await generateImplementation(next.currentSubtask);
      await writeFile(implCode);

      // Run tests
      const results = await runTests();

      // Complete GREEN phase
      await mcp.call('autopilot_complete_phase', {
        projectRoot: '/path/to/project',
        testResults: results
      });

    } else if (next.action === 'commit_changes') {
      // Commit
      const commit = await mcp.call('autopilot_commit', {
        projectRoot: '/path/to/project'
      });

      console.log(`Committed: ${commit.commit.hash}`);

      if (commit.isComplete) {
        console.log('Task complete!');
        break;
      }
    }
  }
}

Error Handling

Common Errors and Solutions

Workflow Already Exists

Error:

{
  "error": "Workflow already in progress",
  "suggestion": "Use autopilot_resume to continue the existing workflow"
}

Solution:

# Resume existing workflow
tm autopilot resume

# OR force start new workflow
tm autopilot start 7 --force

RED Phase Validation Failed

Error:

{
  "error": "RED phase validation failed",
  "reason": "At least one test must be failing in RED phase",
  "actual": { "passed": 10, "failed": 0 },
  "suggestion": "Ensure you have written a failing test before proceeding"
}

Solution: The test isn’t actually testing the new feature. Write a test that validates the new behavior that doesn’t exist yet.

GREEN Phase Validation Failed

Error:

{
  "error": "GREEN phase validation failed",
  "reason": "All tests must pass in GREEN phase",
  "actual": { "passed": 9, "failed": 1 },
  "suggestion": "Fix the implementation to make all tests pass"
}

Solution: Implementation isn’t complete. Debug failing test and fix implementation.

No Staged Changes

Error:

{
  "error": "No staged changes to commit",
  "suggestion": "Make code changes before committing"
}

Solution: Ensure you’ve actually created/modified files before committing.

Git Working Tree Not Clean

Error:

{
  "error": "Git validation failed: working tree not clean",
  "suggestion": "Commit or stash changes before starting workflow"
}

Solution:

git status
git add . && git commit -m "chore: save work"
# Then start workflow

Error Recovery Patterns

Retry Pattern

async function withRetry<T>(
  fn: () => Promise<T>,
  maxAttempts: number = 3
): Promise<T> {
  for (let attempt = 1; attempt <= maxAttempts; attempt++) {
    try {
      return await fn();
    } catch (error) {
      if (attempt === maxAttempts) throw error;
      console.log(`Attempt ${attempt} failed, retrying...`);
      await sleep(1000 * attempt); // Exponential backoff
    }
  }
  throw new Error('Should not reach here');
}

// Usage
const results = await withRetry(async () => {
  const output = await runTests();
  return parseTestResults(output);
});

Graceful Degradation

async function completePhase(projectRoot: string, results: TestResults) {
  try {
    return await mcp.call('autopilot_complete_phase', {
      projectRoot,
      testResults: results
    });
  } catch (error) {
    console.error('Phase completion failed:', error);

    // Log error for debugging
    await logError(error);

    // Attempt manual recovery
    console.log('Attempting manual state recovery...');
    const status = await mcp.call('autopilot_status', { projectRoot });
    console.log('Current state:', status);

    // Provide user guidance
    console.log('Manual intervention required:');
    console.log('1. Check test results are correct');
    console.log('2. Verify current phase allows transition');
    console.log('3. Run: tm autopilot status');

    throw error;
  }
}

Troubleshooting

Workflow State Issues

Problem: State file corrupted or inconsistent Solution:

# Check state file
cat .taskmaster/workflow-state.json

# If corrupted, abort and restart
tm autopilot abort --force
tm autopilot start 7

Test Results Parsing

Problem: Test output format not recognized Solution: Ensure test results JSON has required fields:

{
  "total": 10,    // Required
  "passed": 8,    // Required
  "failed": 2,    // Required
  "skipped": 0    // Optional
}

Branch Conflicts

Problem: Workflow branch already exists Solution:

# Check branches
git branch

# Delete old workflow branch if safe
git branch -D task-7

# Start workflow again
tm autopilot start 7

Permission Issues

Problem: Cannot write to .taskmaster directory Solution:

# Check directory permissions
ls -la .taskmaster/

# Fix permissions
chmod -R u+w .taskmaster/

State Persistence Failures

Problem: State not saving between commands Solution:

# Check file system permissions
ls -la .taskmaster/workflow-state.json

# Verify state is being written
tm autopilot status --json | jq .

# If all else fails, reinstall
rm -rf .taskmaster/
tm init

Working with AI Agents

Example prompts for AI agents (Claude Code, Cursor, etc.) to use the TDD workflow.

Starting a Task

I want to implement Task 7 using TDD workflow. Please:
Start the autopilot workflow
Show me the first subtask to implement
Begin the RED-GREEN-COMMIT cycle

RED Phase - Writing Failing Tests

We're in RED phase for subtask "{SUBTASK_TITLE}". Please:
Read the subtask requirements
Write a test that validates the behavior
The test MUST fail because the feature doesn't exist yet
Run the tests and report results to complete the RED phase

GREEN Phase - Implementing

We're in GREEN phase. The test is failing with: {ERROR_MESSAGE}

Please:
1. Implement the minimal code to make this test pass
2. Don't over-engineer or add untested features
3. Run tests and report results to complete the GREEN phase

Handling Errors

The RED phase validation failed - no test failures detected.

Please:
1. Review the test I just wrote
2. Identify why it's not actually testing new behavior
3. Rewrite the test to properly fail until the feature is implemented

GREEN phase validation failed - {N} tests still failing.

Please:
1. Review the failing test output
2. Fix the implementation to pass all tests
3. Try completing the GREEN phase again

Checking Progress

What's the current state of the workflow? Please show:
- Which subtask we're on
- Current TDD phase (RED/GREEN/COMMIT)
- Progress percentage
- Next action required

Resuming Work

I have an in-progress workflow. Please:
Resume the autopilot workflow
Show current status
Continue from where we left off
