When should I use the Use Case 2.0 skill?

Use it when modeling system behavior from a user perspective, planning releases using slices, or when you need to understand the full scope of actor goals and system responses.

How does this skill help in creating user stories?

The skill provides a mapping pattern where each use case slice is converted into one or more user stories, automatically including acceptance criteria and test scenarios.

Does this skill support error handling requirements?

Yes, it specifically includes templates for Exception Flows and Alternative Flows to ensure that edge cases and error conditions are documented before implementation starts.

What is the difference between a traditional use case and Use Case 2.0?

Use Case 2.0 is designed for agile teams; it replaces heavy documentation with 'slices'—small, implementable parts of a use case that provide incremental value and fit within a single sprint.

コラボレーションツール

Implements Ivar Jacobson's Use Case 2.0 methodology to model system behavior and derive agile user stories.

概要

The Use Case 2.0 skill brings a modern, lightweight approach to requirements elicitation within Claude Code. By integrating Ivar Jacobson's proven methodology, it helps teams bridge the gap between structured system modeling and agile execution. The skill guides you through identifying actors, defining goals, and breaking down complex behaviors into implementable 'slices' that deliver incremental value. Whether you are documenting complex alternative paths or converting functional requirements into developer-ready user stories, this skill ensures your specifications are traceable, testable, and aligned with stakeholder needs.
