Repro steps engineers actually act on

"Cannot reproduce" is a verdict. It's also a mirror: most of the time, the steps simply weren't precise enough.

The three properties of a good repro

1. Deterministic: the same steps produce the same outcome every time.
2. Minimal: removing any step makes it stop reproducing.
3. Portable: a stranger with a fresh account can run them.

Common failure modes

• Hidden state from a previous tab.
• Cached responses that won't reproduce on a clean session.
• Race conditions that need a specific timing.
• Account-shape assumptions (admin vs member, paid vs free).

Checklist before you file

• Open a fresh incognito window.
• Log in as the smallest viable account.
• Run the steps from the very first click.
• Note the URL and viewport at each step.
