Before and after text for Slack
Rough request on the left, the PromptDC rewrite on the right.
Before
billing sandbox down release moved thurs qa starts again wed morning
After
The billing sandbox is unavailable. The release is moving to Thursday as a result. QA will resume on Wednesday morning.
Why this is better: The text separates the blocker, release impact, and next QA step for a scannable Slack update.
Before
spinner should show while saving then go away when success toast shows
After
The loading spinner should appear while the save is in progress. It should disappear after the save succeeds. The confirmation toast should appear at that point.
Why this is better: The text defines the UI sequence precisely, giving the Slack design thread an actionable answer.
Before

After
The customer import is complete. It processed 12,000 rows, with 14 failures. The failure CSV is available in #ops.
Why this is better: The text foregrounds the result, failure count, and file location for a concise Slack update.
