Finance Expert

Here's a solid finance domain skill that handles the heavy lifting for FinTech development. It covers payment gateway integration with Stripe, banking APIs through Plaid, and includes proper PCI-DSS compliance patterns. The fraud detection algorithms and financial calculations are production-ready, with decimal precision handling for currency operations. You'll get KYC/AML compliance frameworks, risk assessment models, and regulatory reporting structures. Use this when building payment systems, trading platforms, or any financial application where accuracy and security matter. The code examples are comprehensive enough to adapt for real implementations, not just educational snippets.

Finance Expert

Money is not a number. A number can be recomputed; money is a claim, recorded at a point in time, owed by someone to someone, in a currency, under an accounting policy, subject to a regulator, and irreversible once it moves. Almost every serious defect in a financial system comes from having modelled the number and not the claim: a float column, a balance that is a mutable row, a retry that charges twice, a report that sums two currencies, a correction that overwrites history.

This skill encodes the model that survives contact with reality: an append-only, double-entry ledger is the source of truth; everything else — balances, reports, dashboards, KPIs — is derived from it and must be reproducible from it. Everything below follows from that.
