Healthcare: Claims Denial Appeal Preparation with Codex: Sandbox Policy
A production playbook for claims denial appeal preparation in healthcare operations using Codex: sandbox policy, run-scoped inputs, logs, typed results, and artifacts.
Audience: Revenue cycle teams appealing payer denials
The problem
Revenue cycle teams appealing payer denials need claims denial appeal preparation to run repeatedly against EOBs, denial letters, medical records, payer policies, and appeal templates. In healthcare operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.
Implementation path
Run claims denial appeal preparation 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 claims denial appeal preparation, 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
