Contract Review with Claude Code: Result JSON Schema

A production playbook for contract review in cross-industry operations using Claude Code: result json schema, run-scoped inputs, logs, typed results, and artifacts.

Audience: Legal operations teams

The problem

Legal operations teams need contract review to run repeatedly against contracts, redlines, exhibits, and policy memos. In cross-industry operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.

Implementation path

Define the outer result contract once, let the contract review skill own body.data, and reject terminal output that does not match the expected schema.

Tradeoffs and failure modes

Schema enforcement adds upfront design work, but removes prompt parsing from the product surface. For contract review, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
