Start with a one-line symptom and the exact route to reproduce it: starting state, action, and visible result. Then provide expected behavior, actual behavior, environment, and frequency. Attach a small safe sample or a short log excerpt if it distinguishes the issue; avoid dumping an entire console session.
For example: “With two images selected, removing the first thumbnail removes both. Expected: only the selected image disappears. Reproduced in Firefox on desktop, three out of three attempts.” Mention any workaround separately from the bug. End by asking for a specific check or confirmation. An investigator should be able to reproduce the failure before debating its cause.
