📦 Beta Release - Ready to use, actively improving. Report issues →

One command installs AI-DLC (AI-Driven Development Life Cycle) with SDD (Spec-Driven Development) workflows for Claude Code and Gemini CLI.

# Basic installation (default: Claude Code)
npx cc-sdd@latest

# With language: --lang en (English) or --lang ja (Japanese) or --lang zh-TW (Traditional Chinese)
# With OS: --os mac or --os windows (if auto-detection fails)
npx cc-sdd@latest --lang ja --os mac

# With different agents: gemini-cli
npx cc-sdd@latest --gemini-cli

# Ready to go! Now Claude Code and Gemini CLI can leverage `/kiro:spec-init <what to build>` and the full SDD workflow

After running cc-sdd, you'll have:

• 8 powerful slash commands (/kiro:steering, /kiro:spec-requirements, etc.)
• Project Memory (steering) - AI learns your codebase, patterns, and preferences
• Structured AI-DLC workflow with quality gates and approvals
• Spec-Driven Development methodology built-in
• Kiro IDE compatibility for seamless spec management

Perfect for: Feature development, code reviews, technical planning, and maintaining development standards across your team.

Includes Claude Code your project context, Project Memory (steering) and development patterns: requirements → design → tasks → implementation. Kiro IDE compatible — Reuse Kiro-style SDD specs and workflows seamlessly.

【Claude Code/Gemini CLI】ワンライナーで AI-DLC（AI-Driven Development Life Cycle） と Spec-Driven Development（仕様駆動開発） のワークフローを導入。プロジェクト直下に Slash Commands 一式と設定ファイル（Claude Code用の CLAUDE.md / Gemini CLI用の GEMINI.md）を配置し、プロジェクトの文脈と開発パターン（要件 → 設計 → タスク → 実装）、プロジェクトメモリ（ステアリング） を含みます。

📖 Project Overview (Spec-Driven Development workflow) • 日本語: README_ja.md • English: README_en.md • 繁體中文: README_zh-TW.md

Transform your agentic development workflow with Spec-Driven Development

• ✅ Claude Code - Fully supported with all 8 custom slash commands and CLAUDE.md
• ✅ Gemini CLI - Fully supported with all 8 custom commands and GEMINI.md
• 📅 More agents - Additional AI coding assistants planned

Currently optimized for Claude Code. Use --agent claude-code (default) for full functionality.

Step 0: Setup Project Memory (Recommended)

# Teach Claude Code about your project
/kiro:steering

SDD Development Flow:

# 1. Start a new feature spec
/kiro:spec-init User authentication with OAuth and 2FA

# 2. Generate detailed requirements  
/kiro:spec-requirements user-auth

# 3. Create technical design (after requirements review)
/kiro:spec-design user-auth -y

# 4. Break down into tasks (after design review)  
/kiro:spec-tasks user-auth -y

# 5. Implement with TDD (after task review)
/kiro:spec-impl user-auth 1.1,1.2,1.3

Quality Gates: Each phase requires human approval before proceeding (use -y to auto-approve).

# Choose language and OS
npx cc-sdd@latest --lang ja --os mac

# Preview changes before applying
npx cc-sdd@latest --dry-run

# Safe update with backup
npx cc-sdd@latest --backup --overwrite force

# Custom specs directory
npx cc-sdd@latest --kiro-dir docs/specs

✅ AI-DLC Integration - Complete AI-Driven Development Life Cycle
✅ Project Memory - Steering that learns your codebase and patterns
✅ Spec-Driven Development - Structured requirements → design → tasks → implementation
✅ Cross-Platform - macOS and Windows support with auto-detection
✅ Multi-Language - Japanese, English, Traditional Chinese
✅ Safe Updates - Interactive prompts with backup options
