OpenAPI Compatibility Checklist
Catch breaking changes before they ship. Diff the old and new OpenAPI spec, then confirm each category below.
When to use this
- Before bumping your OpenAPI version.
- Before merging a spec PR that touches existing endpoints.
- When a consumer reports an unexpected breakage.
How this checklist works
Some items run a quick local check (e.g. scanning sample responses for secrets or PII). Others are manual confirmations or open another tool. When you finish, copy the report as Markdown to paste into your PR description, ticket, or Slack.

This page is a static HTML file. The checklist component runs locally in your browser. Inputs you paste into the Run boxes stay in memory and are discarded when you close the tab. If you turn on "Save in this browser", only check state and short evidence strings are saved to localStorage — never the raw inputs.
