How to test

Motivation and context

The Jira ticket is intended to be copied into the "Text of the Ticket" section for improved context of automated AI reviewers. This content, especially when verbose, can be very distracting for humans.

When editing Markdown in the Github Markdown editor, you can try using the /details command to interactively create a collapsible <details> section. It uses HTML markup because there is no direct Markdown equivalent for such a section.
