🎯 What is Gigaspec?

Gigaspec is an AI-native collaboration framework that transforms how software projects are planned and built. Instead of static templates or keyword-based recommendations, Gigaspec enables deep AI analysis of your requirements with intelligent Q&A workflows.

The Problem with Traditional Tools

User: "I want to build a real-time collaborative app"
Traditional Tool: "Use Elixir!" ← No questions, no reasoning

The Gigaspec Way

User: "I want to build a real-time collaborative app"
AI: "Tell me more! What's your expected user count? Do you need 
     offline support? What's your team's expertise?"
     
     → Analyzes deeply
     → Explains reasoning  
     → Recommends tailored stack

🚀 Quick Start

Installation

# Global installation
npm install -g gigaspec

# Or use without installing
npx gigaspec init --name "MyApp"

Create Your First Project

# Interactive AI-guided wizard
gigaspec init

# Or specify your stack directly
gigaspec init --name "MyApp" --stack "Node.js/Next.js"

# Non-interactive with defaults
gigaspec init --name "MyApp" --yes

# Generate v5.0 Ultimate Spec Kit (RECOMMENDED)
gigaspec generate --name "MyApp" --stack "Node.js/Express" --v5

🚀 Gigaspec v5.0 (Ultimate Spec Kit)

The specification framework that forces AI compliance.

# Generate v5.0 spec kit with immutable rules
gigaspec generate --name "MyApp" --stack "Node.js/Express" --v5

What makes v5.0 different:

CLAUDE.md - Immutable system rules that AI cannot override
Automated Verification - Every code change validated
Multi-Tool Adapters - Claude Code, Cursor, Kimi support
Model-Agnostic - Works with any LLM
