3. superpowers - World-Class Engineer Standard Workflow

⭐ GitHub Stars: Growing | 📦 Project Type: Development Workflow Skills

Developer @obra felt that current AI code generation is too casual, so he created a set of Skills that forces Claude to work according to world-class senior engineer standards.

Core Philosophy:

superpowers is like an advanced skill package specifically designed for programmers. After installation, Claude's workflow becomes:

Receive Requirements → Brainstorm → Create Detailed Plan → Write Test Cases (TDD) → Write Code to Pass Tests → Quality Check

Key Skills:

🧠 brainstorm (Brainstorming): Thorough thinking before writing code
📋 write-plan (Planning): Generate detailed Markdown planning documents
✅ TDD Workflow: Write tests first, then code
🔍 Quality Check: Code review and optimization suggestions

Difference from Traditional AI:

Unlike conventional AI that directly writes business code with bugs left to chance, superpowers ensures every feature goes through a complete development process—from design to testing to quality checks—with guarantees at every step.

Use Cases:

Complex feature development: Requires detailed planning and testing
Team collaboration: Ensures code quality and consistency
Learning best practices: Understanding how world-class engineers work

Real-World Example:

When a team using superpowers develops new features, Claude first generates a detailed development plan including:

Feature requirement analysis
Technical solution design
Test case planning
Potential risk identification

Only after you confirm the plan does it start writing code, strictly following TDD workflow to ensure code quality.
