Use this when
A job is small enough to fix, but vague enough to rot.
One failing case. Do not describe “the workflow is broken.” Capture the exact input, file, row, URL, prompt, or trigger that fails.
One expected result. Write the output you wanted before anyone touches the system.
One verification step. Name the command, screen, API call, or replay that proves the fix worked.
One boundary. State what must not be changed: production data, auth, schema, brand copy, budget, or legal terms.
