No ambiguous language ("should", "might", "could")
Edge cases are covered
Error states are defined
Performance expectations stated (if relevant)
Key Rules
ALWAYS use Given/When/Then structure
MUST make each criterion independently testable
ALWAYS include edge cases and error scenarios
NEVER use vague language - be specific
Common Mistakes
❌ Vague criteria ("works correctly") → ✅ Specific conditions
❌ Missing edge cases → ✅ Include boundary conditions
❌ Implementation details → ✅ Focus on observable behavior
