About
The domain-fintech skill equips Claude with specialized knowledge for architecting financial systems using Rust, focusing on mission-critical requirements like exact decimal precision and regulatory auditability. It enforces strict development rules—such as prohibiting floating-point numbers for currency—and promotes best practices like the event sourcing pattern, double-entry accounting, and immutable record-keeping. By integrating specific crates like rust_decimal and implementing type-driven design patterns, it ensures that financial applications are robust, deterministic, and compliant with industry standards.
