Fintech: Merchant Underwriting Review with Codex: Sandbox Policy
A production playbook for merchant underwriting review in fintech operations using Codex: sandbox policy, run-scoped inputs, logs, typed results, and artifacts.
Audience: Fintech risk teams underwriting merchants
The problem
Fintech risk teams underwriting merchants need merchant underwriting review to run repeatedly against applications, bank statements, websites, KYC docs, and risk policies. In fintech operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.
Implementation path
Run merchant underwriting review in an ephemeral sandbox, keep provider credentials in the broker, expose narrow tools, and store logs outside the workspace for review.
Tradeoffs and failure modes
A narrower runtime blocks ambient machine behavior, but it gives security reviewers a concrete boundary. For merchant underwriting review, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
Runtime boundary
filesystem: /skill and /skill/.argo/inputs only
network: deny by default
artifacts: /skill/output/artifacts
logs: retained outside sandbox
provider: Codex
