Write Use Cases

Use this skill to design, author, and validate structured Use Case specifications adhering to Alistair Cockburn's scoping rules and Karl Wiegers' 13-field template.

When to Use

• converting business goals into sequential, actor-driven interaction specifications
• scoping complex multi-step workflows with branch conditions and failure states
• distinguishing Elementary Business Processes (EBPs) from business workflows and subfunctions
• establishing clear boundaries between system responsibilities and human actor tasks
• reviewing and refactoring poorly scoped, UI-dependent, or happy-path-only use cases
• generating verifiable test scenario baselines for QA and automated E2E testing
