Make a minimal example safe enough to publish

Keep the smallest input that still reproduces the problem, along with the expected and actual result. Replace real names, email addresses, IDs, tokens, and private URLs with clearly synthetic values.

Run the sanitized example again. If the issue disappears, preserve the property that mattered—perhaps a comma, newline, long number, or empty field—without keeping the sensitive value. Inspect screenshots, logs, and file metadata too; secrets can hide outside the visible example.

A useful forum example lets another person reproduce the behavior without access to your account.
