Implementation Task Creator

Create task files that break down components into implementable TDD steps.

Activation

Activate when you detect:

• "Break down X for implementation"
• "Create task for X"
• Moving from Phase 2 to Phase 3
• Need implementation tasks for a component

Workflow

1. Load Component Architecture

Use Read on {project_path}/architecture/{component}.md

If file doesn't exist, ask: "No architecture found for {component}. Create architecture first?"

Extract:

• Component purpose
• Interface (methods, parameters)
• Dependencies
• Pattern reference
• Acceptance criteria

2. Determine Task Scope

Ask user:

How should this component be broken down?
1. Single task (small component)
2. Multiple tasks by method/feature
3. Multiple tasks by layer (test, implementation, integration)

Your choice:

3. Define Task Order

Based on dependencies, determine implementation order. Ask:

Proposed task order:
1. {task 1} - {why first}
2. {task 2} - {depends on 1}
3. {task 3} - {depends on 2}

Adjust order? (yes/no)

4. Create Task File(s)

For each task, use Write to create {project_path}/implementation_process/in_progress/{nn}_{task_name}.md:

# Task: {Task Name}

**Component:** {component name}
**Created:** {YYYY-MM-DD}
**Status:** Not Started
**Priority:** {nn}

## Objective
{What this task accomplishes - one paragraph}

## Prerequisites
- [ ] {Task that must be complete first, or "None"}

## Acceptance Criteria
- [ ] {Criterion 1 - specific and testable}
- [ ] {Criterion 2}
- [ ] {Criterion 3}
- [ ] All tests pass
- [ ] Code follows Drupal standards

## TDD Steps

### Step 1: Write Failing Test
Create test file:

tests/src/{Unit|Kernel}/{TestClass}Test.php

Test case:
```php
public function test{MethodName}(): void {
  // Arrange: {setup}
  // Act: {action}
  // Assert: {expected result}
}

Step 2: Verify Test Fails

Run: ddev phpunit {test_path} Expected: Test fails (class/method not found)

Step 3: Write Minimum Implementation

Create: src/{Type}/{ClassName}.php Implement only enough to pass the test.

Step 4: Verify Test Passes

Run: ddev phpunit {test_path} Expected: Test passes

Step 5: Refactor

Clean up code while keeping tests green.

Files to Create/Modify

File	Action	Purpose
src/{path}	Create	Main implementation
tests/src/{path}	Create	Test coverage
*.services.yml	Modify	Service registration

Pattern Reference

Follow: {core path from architecture}

Key aspects:

• {what to copy from pattern}
• {what to adapt}

Notes

{Any specific considerations from architecture}

### 5. Update project_state.md

Use `Edit` to update the project state:
```markdown
## Current Focus
Implementation Phase - {component name}

## Next Steps
1. Complete task: {first task name}

6. Confirm

Show user:

Created {count} task(s) for {component}:
1. {task 1} - in_progress/{filename}
2. {task 2} - in_progress/{filename}

Start with task 1? Use: /drupal-dev-framework:implement {task_name}

Stop Points

STOP and wait for user:

• If architecture file not found
• After asking about task breakdown
• After showing proposed order
• After creating files (confirm before proceeding)
