Code Migration Planning with Claude Code: Result JSON Schema
A production playbook for code migration planning in cross-industry operations using Claude Code: result json schema, run-scoped inputs, logs, typed results, and artifacts.
Audience: Engineering teams preparing framework or API migrations
The problem
Engineering teams preparing framework or API migrations need code migration planning to run repeatedly against repository snapshots, target docs, and compatibility notes. 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 code migration planning 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 code migration planning, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
