Practical guides to building AI agents with Claude Code, Codex, and Runtime. From payment investigations to production operations.
An agent harness is the software around an AI model that gives it a computer, tools, memory, permissions, and an audit trail. How it works in payments.
A system of intelligence sits above your systems of record and turns every case into memory the next one can use. Origin, examples, and how it works.
A system of record stores what happened. A system of intelligence learns why, and what to do next. A side-by-side comparison with payment examples.
Systems of action do the work. Systems of intelligence decide which work to do and remember how it went. How they fit together, with payment ops examples.
A plain-English guide for ops managers and analysts: how AI coding agents take over the weekly report, the ERP exports, the trackers, and the reconciliations, with you still holding the sign-off.
Give a coding agent safe, read-only access to your logs, data, and repos, and the technical tickets that used to wait days on engineering close the same day.
Use Jev, TypeSafe's System One model, as a pre-trigger that triages, ranks, and routes support tickets and alerts before a Claude Code or Codex agent investigates in a Runtime sandbox. Covers payment ops, support, and incident response.
Use Jev, TypeSafe's System One model, to triage onboarding applications, KYB and KYC reviews, sanctions and adverse media hits, and AML alerts, then hand the right cases to a Claude Code or Codex agent in a Runtime sandbox.
Build a payment support agent with Claude Code or Codex. Trace declined transactions, check account data, and draft evidence-backed replies with Runtime.
Build AI agents for partner-bank RFIs, hold-harmless requests, and returns of funds. Parse requests, gather evidence, and draft reviewed replies with Runtime.
Use Claude Code or Codex to build KYB and KYC agents that check documents, investigate screening matches, and prepare evidence for human onboarding reviews.
Build a compliance investigation agent with Claude Code or Codex. Gather transaction evidence, draft case narratives, and preserve human review in Runtime.
Build a fraud investigation agent with Codex or Claude Code. Trace transaction patterns, gather account context, and prepare evidence for risk review in Runtime.
Build a payment reconciliation agent with Claude Code or Codex. Explain bank, processor, and ledger differences, then prepare reviewed adjustments in Runtime.
What's actually possible when you point a coding agent at your underwriting playbook: KYB checks, sanctions screening, portfolio reviews, and alert triage, running on a schedule with a human still holding the approval.
A prompt-based guide for GTM engineering and RevOps teams: write the campaign brief yourself, then let a scheduled AI agent source, send, and report on outbound, with a human approving every message.
Build admin dashboards, approval workflows, and data tools in hours instead of weeks. A complete guide using Runtime with Claude Code, Codex, or Gemini CLI.
