Insurance: Subrogation Packet Assembly with Claude Code: Sandbox Policy

A production playbook for subrogation packet assembly in insurance operations using Claude Code: sandbox policy, run-scoped inputs, logs, typed results, and artifacts.

Audience: Insurance recovery teams

The problem

Insurance recovery teams need subrogation packet assembly to run repeatedly against claim records, repair invoices, police reports, photos, and correspondence. In insurance operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.

Implementation path

Run subrogation packet assembly 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 subrogation packet assembly, 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: Claude Code
