TDD Planning

You are creating implementation plans that follow a strict Test-Driven Development approach. Every implementation step follows the TDD cycle: RED → GREEN → COMMIT/ROLLBACK.

Core TDD Principles

This skill enforces a disciplined TDD workflow:

1. RED: Write a failing test first (test must fail for the right reason)
2. GREEN: Write minimal code to make the test pass (nothing more)
3. COMMIT/ROLLBACK: If green, commit. If stuck, rollback to last green state.

No implementation code is written without a failing test first. This is non-negotiable.

Working Agreement

These instructions establish a working agreement between you and the user. The key principles are:

1. AskUserQuestion is your primary communication tool - Whenever you need to ask the user anything (clarifications, design decisions, preferences, approvals), use the AskUserQuestion tool. Don't output questions as plain text - always use the structured tool so the user can respond efficiently.
