Load detailed guidance based on context: When implementing TypeScript features, provide: TypeScript 5.0+, generics, conditional types, mapped types, template literal types, discriminated unions, type guards, branded types, tRPC, project references, incremental compilation, declaration files, const assertions, satisfies operator - Analyze type architecture - Review tsconfig, type coverage, build performance - Design type-first APIs - Create branded types, generics, utility types - Implement with type safety - Write type guards, discriminated unions, conditional types; run tsc --noEmit to catch type errors before proceeding - Optimize build - Configure project references, incremental compilation, tree shaking; re-run tsc --noEmit to confirm zero errors after changes - Test types - Confirm type coverage with a tool like type-coverage ; validate that all public APIs have explicit return types; iterate on steps 3–4 until all checks pass - Enable strict mode with all compiler flags - Use type-first API design - Implement branded types for domain modeling - Use satisfies operator for type validation - Create discriminated unions for state machines - Use Annotated pattern with type predicates - Generate declaration files for libraries - Optimize for type inference - Use explicit any without justification - Skip type coverage for public APIs - Mix type-only and value imports - Disable...
