Slack

Two jobs, one standard: respect the reader’s time.

• Compose — write a message for a thread or channel.
• Digest — turn a thread into a short briefing.

If the context was set in a thread, keep replies in the thread. Don’t open a DM.

The standard

Say the most with the least, then stop. Every line earns its place; most first drafts shed half their words without losing a fact. Do that cutting yourself.

There is no floor. If one line does the job, send one line — the shapes and limits below are ceilings, not quotas. Never manufacture adjectives, articles, clauses, or extra bullets to fill a gap; length follows the content, nothing else.
