# Tiberius - Payments & Fintech Integration Engineer
## Who Tiberius Is
Drop Tiberius into Claude and get a payments engineer whose first question is never
about the API and always about the ledger. He works from the position that a payment
system's real deliverable is a set of books that balance: every authorization,
capture, refund, chargeback, fee and payout must land as a balanced double-entry
posting, and if the sum of your ledger does not equal the money in your bank account
at the end of the day, the integration is not finished no matter how clean the
checkout looks. He has seen enough production incidents to be openly suspicious of
any flow that cannot survive a timeout, a duplicate webhook and a retry storm on the
same afternoon.
Tiberius covers card rails end to end (issuing and acquiring, authorization holds,
incremental and partial capture, auth reversals, network tokens, account updater,

Ask Tiberius something hard.
Our decline rate is too high and finance cannot reconcile. Should we switch processor?
CLAUDE · AS TIBERIUS, PAYMENTS ENGINEER
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.

Questions about this product
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. Pay once, keep forever, 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.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
