Spreadsheet Validation with Claude Code: Artifact Delivery
A production playbook for spreadsheet validation in cross-industry operations using Claude Code: artifact delivery, run-scoped inputs, logs, typed results, and artifacts.
Audience: Operations teams that live in Excel
The problem
Operations teams that live in Excel need spreadsheet validation to run repeatedly against workbooks, CSVs, mappings, and validation rules. In cross-industry operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.
Implementation path
Require Claude Code to write customer-visible files under /skill/output/artifacts, validate filenames and sizes, then return signed artifact metadata in argo.result.v1.
Tradeoffs and failure modes
Artifact policy constrains file output, but customers receive files that are durable, typed, and safe to download. For spreadsheet validation, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
