Implement Feature FAQs

Question 1

What does the Implement Feature skill do?

Accepted Answer

The Implement Feature skill automates the software development lifecycle by transforming task specifications into working code using a strict Test-Driven Development (TDD) workflow. It analyzes requirements, writes failing tests (Red), implements the minimum code to pass (Green), and refactors for quality while ensuring all acceptance criteria are met.

Question 2

What are the prerequisites for using Implement Feature?

Accepted Answer

You must have a task specification file located in your workspace, the 'bmad-commands' skill installed for file operations, and a configured development environment with a supported test framework like Jest or Pytest.

Question 3

Can I use this skill for specific parts of a larger task?

Accepted Answer

Yes. By using the 'subtask_id' input, you can narrow the skill's focus to a specific sub-requirement. This allows for incremental development, smaller commits, and a more manageable implementation process for larger features.

Question 4

When should I use this skill?

Accepted Answer

Use this skill when you have an approved task specification and are ready to begin implementation. It is ideal for simple to medium complexity features (≤60 complexity score) where clear, testable acceptance criteria exist and the changes affect five or fewer files.

Question 5

How does this skill ensure code quality?

Accepted Answer

It enforces a high standard of quality by requiring an automated test coverage threshold of at least 80%. Additionally, it performs deterministic file operations, runs automated validation suites to check for syntax errors, and verifies that every requirement in the task specification has a corresponding passing test.
