Implement Task

Implement Task Skill

When to Use

Use this skill when you have a task with:

• Clear acceptance criteria
• Defined file scope
• Testable requirements

Instructions

Step 1: Analyze the Task

Read the task definition and extract:

• Acceptance criteria (what must be true when done)
• Files to create/modify
• Dependencies on other code

Step 2: Write Failing Tests

For each acceptance criterion:

# tests/test_<feature>.py
def test_<criterion>():
    # Arrange: Set up test data
    ...
    # Act: Call the function/method
    result = function_under_test(...)
    # Assert: Verify expected behavior
    assert result == expected

Run tests to confirm they fail:

pytest tests/test_<feature>.py -v

Step 3: Implement Minimal Code

Write the simplest code that makes tests pass:

• No premature optimization
• No extra features
• Follow existing patterns

Step 4: Verify

Run all tests:

pytest tests/ -v

Step 5: Report

Output format:

{
  "status": "completed",
  "tests_written": 3,
  "tests_passed": 3,
  "files_created": ["src/feature.py"],
  "files_modified": ["src/utils.py"]
}

Completion Signal

When finished, output:

<promise>DONE</promise>
