Features and purpose

Create YAML tax configurations for new countries in the universal salary calculator. Use when: (1) Adding a new country to the calculator, (2) Adding a new tax year for existing country, (3) Creating variant configs (expat regimes, special tax rules), (4) Writing test vectors for configs. Triggers: "add country", "create config for", "new tax year", "add variant", "30% ruling config", etc. IMPORTANT: This skill includes automated test validation. All configs MUST pass `npm run test:configs` before completion. The skill guides you through research, implementation, test creation, validation, and debugging until all tests pass.
