# 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 **22 atomic, stack-agnostic skills** and a
**TDD implementation engine** — with a living 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 (`specify` / `clarify` / `design`) are also **depth-tunable** — an easy / medium / hard
dial decides how much the skill decides for you vs. interrogates you with trade-offs.

## Requirements

SDD runs on **any Claude plan / model tier** — no skill requires a specific model:

- Skills declare `model: inherit` and run on your **session model** — run your SDD session on the
  strongest tier your account has.
- The **judgment agents** (reviewer / critic / devils-advocate / strategist / analyst) *default*
