Requirements clarification for TDD. Use BEFORE RED phase to understand WHAT to test. Asks targeted questions to uncover ambiguities, edge cases, and acceptance criteria.
npx skill4agent add doubleslashse/claude-marketplace requirements-clarification| Question | Purpose |
|---|---|
| What is the primary happy path behavior? | Establish main test scenario |
| What inputs does this feature accept? | Define parameter validation tests |
| What outputs/results are expected? | Define assertion expectations |
| What side effects should occur? | Identify integration points |
| Are there any business rules or constraints? | Identify validation logic |
| Question | Purpose |
|---|---|
| What happens with null/empty input? | Null handling tests |
| What are the boundary values (min/max)? | Boundary condition tests |
| What if required dependencies are unavailable? | Error handling tests |
| Are there concurrency or timing concerns? | Thread safety tests |
| Question | Purpose |
|---|---|
| What exceptions should be thrown and when? | Exception tests |
| How should invalid input be handled? | Validation tests |
| What error messages should users see? | User feedback tests |
| Question | Purpose |
|---|---|
| What interfaces/abstractions already exist? | Understand dependencies |
| What existing patterns should be followed? | Consistency with codebase |
| Are there existing tests to follow as examples? | Test style consistency |
| What is the target test scope (unit/integration)? | Test organization |
