What is the Iron Law of Design in this skill?

The Iron Law dictates that implementation cannot begin until the user has explicitly approved an architectural approach, ensuring alignment and preventing wasted effort.

How does this skill handle large, complex features?

It performs a decomposition check to determine if a feature should be split into multiple independent tasks, prioritizing the first feature and moving others to a BACKLOG.md.

What is the purpose of the PLAN.md file?

The PLAN.md serves as a technical roadmap that includes the chosen approach, rationale, testing strategy, and a task list for the implementation phase.

How many architecture options does it provide?

It typically proposes 2-3 approaches, such as Minimal Changes, Clean Architecture, and a Pragmatic Balance, each with specific trade-offs and estimated code impact.

Does it support Test-Driven Development (TDD)?

Yes, it mandates a TDD strategy where failing tests must be defined and verified for every task before implementation code is written.

Proposes structured architecture approaches and implementation plans with mandatory user approval gates.

The Dev Design skill serves as the blueprint phase of the software development lifecycle, ensuring architectural clarity before a single line of code is written. It generates multiple distinct implementation approaches—ranging from minimal changes to clean architecture—complete with detailed trade-offs and impact estimates. By enforcing a strict 'User Gate,' it prevents premature implementation and ensures that features are properly decomposed into manageable tasks within a standardized PLAN.md format, incorporating rigorous Test-Driven Development (TDD) principles from the start.
