Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Key features implemented:
- Updated tests/test_cases.md to use consistent classification terms across all test cases
- Replaced old classification labels like elementary_arithmetic, algebra, calculus with unified terms such as calculation, algebra_simplification, equation_solving, limit, integration, etc.
- Standardized multi-label classifications to match the unified taxonomy used in SKILL.md and classification.md
- Maintained comprehensive test coverage while ensuring classification consistency

The changes ensure all test cases now use the same classification体系 as defined in the main skill documentation, improving consistency and maintainability of the testing framework.
