Finance: Board Metrics Pack Validation with Claude Code: Sandbox Policy
A production playbook for board metrics pack validation in finance operations using Claude Code: sandbox policy, run-scoped inputs, logs, typed results, and artifacts.
Audience: Finance and founder teams preparing board materials
The problem
Finance and founder teams preparing board materials need board metrics pack validation to run repeatedly against metric exports, spreadsheets, CRM reports, finance models, and deck claims. In finance operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.
Implementation path
Run board metrics pack validation 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 board metrics pack validation, 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
