test-case

Creates end-to-end test case documents (TC-*.md) that chain several use cases into one user journey with a step-by-step Flow table, concrete test data, and final validations. Use when the user asks to "create a test case", "write a test case", "define an end-to-end scenario", "document a user journey for testing", "chain use cases into a test", or mentions a test case document, TC-001, journey test, or end-to-end test scenario. Also trigger whenever the user lists several use case IDs (UC-*) and wants one test definition spanning them — the resulting TC-* document is what e2e test skills (e.g. /playwright-test TC-001) automate.
