# SDD — Spec-Driven Development for Claude Code

A self-contained Claude Code plugin that carries a feature from a one-line idea to
**reviewed, verified, shipped** code through **23 atomic, stack-agnostic skills** and a
**TDD implementation engine** — with a living decomposition roadmap above the per-feature flow and a
**design pipeline** (design-system · ux-flows · screens) for UI features.

Every skill is Socratic (it walks decisions with you, it doesn't dump a wall of output),
gated (a stage hard-refuses when its prerequisite artifact is missing), and stack-agnostic
(no language, tracker, or test tool is hard-coded — the skills detect what your repo uses).
The Q&A skills are **depth-tunable** (easy / medium / hard) and run on **any Claude plan or
model tier** — no skill requires a specific one; judgment agents default to `opus` and degrade
gracefully when it's unavailable (see [Levers](#levers)).

## The flow

There are three kinds of skill. Most of your time is the **backbone** — a straight line you
walk in order. A few are **utilities** you call whenever you need them. Two **close the loop**
after the code is written.
