What does the Tiberius skill do?

Build payments that reconcile: design the ledger, handle declines and retries properly, and tie out to the settlement file. Load it once into Claude Projects and you get a configured Payments & Fintech Integration Engineer without re-explaining context at the start of every session. Measure the system before changing it, prove the change on a real workload in a staging environment, and ship it behind a rollback you have actually tested rather than one you assume works.

How do I install this skill file?

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Tiberius skill?

Without a skill file your AI starts every session as a general assistant. With Tiberius loaded it applies Payments & Fintech Integration Engineer methodology from the first message, with consistent quality every time. Measure the system before changing it, prove the change on a real workload in a staging environment, and ship it behind a rollback you have actually tested rather than one you assume works.

// what's inside

Drop Tiberius into Claude and get a payments engineer whose real deliverable is a ledger that balances, not an integration that returns 200.

Tiberius builds payment systems that reconcile: card flows through authorization, capture, settlement, refund and chargeback, 3-D Secure and SCA exemptions, network tokens and vaulting, PSP integration and orchestration across multiple providers, alternative payment methods and local rails, ACH, SEPA, SWIFT and instant payment schemes, idempotency and exactly-once semantics under retries, the double-entry ledger as the source of truth, reconciliation against processor settlement files, currency handling in minor units and never in floats, a real failure taxonomy with smart retry and dunning logic, PCI DSS scope reduction, fraud-check integration points, and payout and marketplace split flows.

What you get

→Auth, capture, settlement, refund and chargeback lifecycle
→Double-entry ledger design and settlement-file reconciliation

# Tiberius - Payments & Fintech Integration Engineer

You are Tiberius, a payments and fintech integration engineer. The deliverable is a ledger that balances; the integration is just plumbing.

## How you work
1. Classify declines properly before blaming the processor
2. Design the double-entry ledger as the source of truth
3. Make every write idempotent; assume webhooks arrive twice
4. Reconcile against the settlement file until it ties to the cent

Never represent money in a float, never retry a decline that must not be retried, and never call an integration done before it reconciles.

Excerpt from the actual file you'll download.

// try it

prompt

$Our decline rate is too high and finance cannot reconcile. Should we switch processor?

Tiberius returns a decline taxonomy showing which failures are recoverable and how many are self-inflicted, an honest verdict on whether changing processor addresses any of it, a double-entry ledger design with worked journal entries, an idempotency and retry model that survives duplicate webhooks, a reconciliation procedure against the settlement file, and a PCI scope reduction plan.
