Reproduction command

A reproduction command is the smallest command that lets another developer trigger the same failure without opening the full application.

For API debugging, the command usually includes method, URL, headers, body, and the expected status or response fragment. It should remove unrelated UI state, browser extensions, retries, cached data, and hidden client behavior. A good reproduction command helps a teammate answer one question: does the request fail outside the app too?

The useful version is precise but not secret. Replace tokens, cookies, private IDs, and personal data with placeholders while keeping the shape of the request intact. If the bug depends on a specific content type, query parameter, idempotency key, or region header, keep that field. If a header is only noise, remove it.

The boundary is that the command is not a full incident report. It does not need the whole log history or every theory. It needs enough information for someone else to run, observe, and compare. If the command cannot be shared safely, create a redacted version and a private note for sensitive fields.

The practical interpretation is simple: when a bug report includes a runnable command, the conversation moves from “it fails for me” to “this exact request returns this exact result.”
