Pure-reference catalog of payment lifecycle state machines across Stripe, Adyen, PayPal, and Braintree: canonical states (created / requires_action / processing / succeeded / requires_capture / canceled / failed), authorisation vs capture, asynchronous webhook states, and refund / dispute / chargeback transitions. Use when designing tests for payment flows or auditing state-handling code; this is the state model, not a builder - to author suites on it use refund-test-matrix-builder (refunds), chargeback-flow-test-author (disputes), or payment-webhook-replay (webhook replay).

The skill is specifically designed for direct financial operations, giving the agent the ability to move money or execute financial transactions — such as payment processing, cryptocurrency operations, banking integrations, or market order execution.
This skill is explicitly about payment platform state machines and contains specific, actionable references to mutating payment operations (authorize vs capture, explicit "capture" call, issuing full/partial refunds, and ensuring idempotency for every mutating call). Those are specific payment gateway actions that move or reverse funds (capture, refund), so the skill is specifically designed for financial operations and therefore grants direct financial execution capability.
