Can I apply these planning principles to legacy systems?

Yes, the skill provides strategies to implement new features as small, independent E2E slices that integrate progressively with your existing codebase.

Why does this skill prefer vertical slicing over horizontal slicing?

Vertical slicing ensures that every completed task results in a functional feature, allowing for early integration testing and immediate stakeholder feedback, whereas horizontal slicing often hides risks until the very end.

How does E2E-First planning help with risk management?

It prioritizes integration and deployment tasks at the start of the project, surfacing architectural bottlenecks and environment issues before they become costly delays.

What is a 'Walking Skeleton' in this context?

A Walking Skeleton is a tiny implementation of the system that performs a small end-to-end function, proving that the architecture, tools, and CI/CD pipeline are working correctly.

Guides developers in creating End-to-End (E2E) first development plans using vertical slicing and Walking Skeleton patterns.

About

The E2E-First Planning skill empowers developers and project leads to shift from risky horizontal development toward a robust vertical slice approach. By focusing on the 'Walking Skeleton' and MVP definitions, it helps identify integration risks early, ensures continuous delivery of user value, and creates a clear roadmap from initial architecture to a production-ready product. This skill provides structured frameworks for task decomposition and milestone design, making it indispensable for agile teams aiming for rapid, reliable delivery and shortened feedback loops.

Walking Skeleton architectural planning and setup
1 GitHub stars
MVP scope definition and priority mapping
Risk management via early integration testing

Use Cases

Breaking down complex user stories into actionable, testable vertical tasks
Drafting the initial technical roadmap for a new full-stack application
Communicating development phases and 'Walking Skeleton' goals to stakeholders
