Why does this skill prohibit f64 for currency?

Floating-point numbers (f64) can lead to precision loss and rounding errors; this skill mandates the use of rust_decimal to ensure every cent is accounted for accurately.

How does this skill help with regulatory compliance?

It enforces immutable record-keeping and structured tracing patterns, ensuring every transaction has a clear, unchangeable audit trail required by financial regulators.

What crates are recommended for FinTech development?

The skill prioritizes rust_decimal for math, chrono for time management, uuid for unique transaction identifiers, and validator for strict data integrity.

Can I use this for ledger or DeFi development?

Yes, the architectural patterns provided, such as event sourcing and double-entry accounting principles, are ideal for ledgers and decentralized finance systems.

Provides domain-specific constraints and architectural patterns for building high-precision, compliant financial applications in Rust.

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.
