✨ Transform Claude Code/ Cursor IDE / Gemini CLI from prototype to production-ready development

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

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

# With language: --lang en|ja|zh-TW|zh|es|pt|de|fr|ru|it|ko|ar
# With OS: --os mac | --os windows | --os linux (if auto-detection fails)
npx cc-sdd@latest --lang ja --os mac

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

# 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:

• 10 powerful slash commands (/kiro:steering, /kiro:spec-requirements, /kiro:validate-gap, 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.

• English (en)
• Japanese (ja)
• Traditional Chinese (zh-TW)
• Chinese (zh)
• Spanish (es)
• Portuguese (pt)
• German (de)
• French (fr)
• Russian (ru)
• Italian (it)
• Korean (ko)
• Arabic (ar)

Brings to Claude Code, Cursor IDE and Gemini CLI 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/Cursor IDE/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 10個のSlash Commands 一式と設定ファイル（Claude Code用の CLAUDE.md / Cursor IDE用の AGENTS.md / Gemini CLI用の GEMINI.md）を配置、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） を含む。

📖 Project Overview (Spec-Driven Development workflow)

• 日本語: README_ja.md
• English: README.md
• 繁體中文: README_zh-TW.md

Transform your agentic development workflow with Spec-Driven Development

• ✅ Claude Code - Fully supported with all 10 custom slash commands and CLAUDE.md
• ✅ Gemini CLI - Fully supported with all 10 custom commands and GEMINI.md
• ✅ Cursor IDE - Fully supported with all 10 custom commands and AGENTS.md
• 📅 More agents - Additional AI coding assistants planned

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

# Start spec-driven development immediately
/kiro:spec-init User authentication with OAuth and 2FA
/kiro:spec-requirements user-auth
/kiro:spec-design user-auth -y
/kiro:spec-tasks user-auth -y
/kiro:spec-impl user-auth 1.1,1.2,1.3

📁 Example Spec: See photo-albums-en for a complete spec-driven development example with requirements, design, and tasks.

# First establish project context
/kiro:steering                                    # AI learns existing project context

# Then proceed with development
/kiro:spec-init Add OAuth to existing auth system
/kiro:spec-requirements oauth-enhancement
/kiro:validate-gap oauth-enhancement              # Optional: analyze existing vs requirements
/kiro:spec-design oauth-enhancement -y
/kiro:validate-design oauth-enhancement           # Optional: validate design integration
/kiro:spec-tasks oauth-enhancement -y
/kiro:spec-impl oauth-enhancement 1.1,1.2,1.3

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

Specs as Foundation: Based on Kiro's proven methodology - specs transform ad-hoc development into systematic workflows. Created specs are portable to Kiro IDE for enhanced implementation guardrails and team collaboration.

# 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 documents that maintain comprehensive context (architecture, patterns, rules, domain knowledge) across all sessions
✅ Spec-Driven Development - Structured requirements → design → tasks → implementation
✅ Cross-Platform - macOS, Linux, and Windows support with auto-detection (Linux reuses mac templates)
✅ Multi-Language - Japanese, English, Traditional Chinese
✅ Safe Updates - Interactive prompts with backup options
