SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill helps manage technical uncertainty and architecture validation by guiding the creation of thin vertical slices, ensuring real integration before full implementation.

Core Features & Use Cases

  • Uncertainty Reduction: Provides a structured approach to validate architecture and integration before committing to full implementation.
  • Vertical Slicing: Guides through identifying slices, defining tracers, building, and evaluating.
  • Use Case: When working on a large feature with multiple system layers, use this Skill to build a single end-to-end path before expanding into full implementation.

Quick Start

On any feature branch, invoke /tracer-bullets to guide through the process of building a tracer bullet.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate system integration before committing to full implementation?

Validate system integration by building thin vertical slices that test a single end-to-end path through all system layers before expanding into full implementation.

What is the tracer bullet approach for reducing architectural uncertainty?

The tracer bullet approach reduces architectural uncertainty by guiding the creation of thin vertical slices to ensure real integration works before full feature implementation.

When should I use vertical slicing for architecture validation?

Use vertical slicing for architecture validation when working on large features with multiple system layers and you need to confirm real integration before full implementation.

How do I build a tracer bullet on my feature branch?

Build a tracer bullet by invoking the tracer-bullets Skill on your feature branch, then manually executing the guided steps to identify slices, define tracers, build, and evaluate.

What are the limitations of using vertical slices for system validation?

Vertical slices for system validation require manual execution of steps and real code integration, meaning you must actively build and evaluate the path rather than relying on automated generation.
