SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill drives approved technical plans by guiding the user through each phase of a plan, using a test-first approach to ensure high-quality and bug-free implementations.

Core Features & Use Cases

Test-First Development: Ensures every phase is designed and implemented around passing tests first.
Plan Execution: Guides through reading and understanding the plan, creating tasks for each phase, and driving towards implementation.
TDD Eligibility Checks: Verifies whether each phase is suitable for test-driven development before proceeding.
Red-Green-Refactor Loop: Encourages a structured and systematic approach to implementing each phase.

Quick Start

Run the 10x-tdd command followed by the change ID and the phase number you want to implement, e.g., 10x-tdd context/changes/my-change-id/plan.md phase 1.

FAQPage Schema

How do I implement a technical plan using test-driven development?▼

To implement a technical plan using test-driven development, the Skill reads your plan documentation and guides you through each phase using a test-first methodology to ensure a high-quality, bug-free implementation.

What is the red-green-refactor loop for plan execution?▼

The red-green-refactor loop is a structured test-driven development practice where you write a failing test, create the implementation to pass the test, and then refactor the code for each phase of your plan.

Do I need a test runner to start test-driven development on a new plan?▼

Yes, you need a test runner configured in your environment before starting test-driven development, as the Skill assumes implementation has not begun and requires you to confirm the presence of required test infrastructure.

How do I execute a specific phase of a plan document with test-first development?▼

You execute a specific phase by providing the change ID and phase number, allowing the Skill to check TDD eligibility for that phase and systematically guide the implementation using test-first practices.

Can I use this for plan implementation if the coding has already started?▼

No, this test-driven development approach assumes implementation has not yet begun, meaning it is designed to drive approved technical plans from the very first test rather than applying tests to existing code.
