Transform your coding workflow with AI-powered Spec-Driven Development. One command installs 11 powerful slash commands, Project Memory, and structured development workflows for 7 AI coding agents based on the AI-Assisted SDD methodology.

Package Exports

  • ai-sdd/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ai-sdd) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

ai-sdd: AI-Assisted Spec-Driven Development

AI multiplies whatever you feed it. Feed it structure — specs, designs, tasks — and it multiplies your velocity. Feed it chaos, and it multiplies your mistakes.

The Problem

Every AI coding agent shares the same fundamental weakness: it cannot infer what you actually meant. It will confidently build the wrong thing, in the wrong way, at the wrong layer — unless you give it a contract first.

That contract is a specification.

The Methodology

AI-Assisted Spec-Driven Development (AI-SDD) is a structured collaboration model built on three roles:

  • Director — You define intent, constraints, and approve each phase
  • Executor — The AI implements within the boundaries you set
  • Contract — Specs (requirements, design, tasks) are the shared language that keeps both aligned

The methodology covers the complete development lifecycle: Requirements → Design → Tasks → Implementation → Validation — with human approval gates between each phase.

The complete methodology is documented at ai-sdd.com.

The Tool

ai-sdd is the NPM package that operationalizes the AI-SDD methodology across 7 AI coding agents: Claude Code, Cursor, Gemini CLI, Codex CLI, GitHub Copilot, Qwen Code, and Windsurf.

# Install in your project (30 seconds)
cd your-project
npx ai-sdd

Once installed, /sdd: slash commands guide you and your AI agent through each phase of the spec-driven workflow.

Supports 7 agents × 12 languages.
