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