🚀 Quick Start

For Vibecoding (Rapid Prototyping)

• Start with cheatsheets/vibecoding-vs-spec-driven.md
• Use when exploring ideas, testing hypotheses, or creating demos
• Perfect for: MVPs, prototypes, user research sprints

For Spec-Driven Development (Production-Ready)

• Follow the frameworks in cheatsheets/
• Use when building production features, scaling systems, or working in teams
• Perfect for: Production code, maintainable systems, team collaboration

For API Development

• Check out cheatsheets/curl-cheatsheet.md

💡 Philosophy

"Move fast, but with purpose." — Product With Attitude

This repository embodies two core principles:

1. Ship faster, break fewer things: Product-grade AI builds need guardrails and systems
2. Reduce entropy: Spec-driven scaffolds + vibecoding loops keep development on track

---

🎓 When to Use Each Approach

Use Vibecoding When:

• Exploring new ideas or UX concepts
• Testing hypotheses quickly
• Creating demos for stakeholder feedback
• Prototyping before committing to architecture

Use Spec-Driven When:

• Building production features
• Working with distributed teams
• Maintaining complex systems
• Ensuring long-term maintainability

The Sweet Spot:

Cycle between both: vibe → spec → vibe → spec as your project evolves.
