3
4# Send initial status message
5MSGID=$(cord send 123456789 "🤖 Processing..." | grep -o '[0-9]*$')
6
7# Update state as work progresses
8cord state 123456789 $MSGID searching
9cord state 123456789 $MSGID writing
10cord state 123456789 $MSGID done

Or with custom progress:

bash
1cord state 123456789 $MSGID "🔄 Step 1/3: Fetching data..."
2cord state 123456789 $MSGID "🔄 Step 2/3: Processing..."
3cord state 123456789 $MSGID "🔄 Step 3/3: Generating report..."
4cord state 123456789 $MSGID done

Report delivery

bash
1# Send summary embed
2cord embed 123456789 "Weekly metrics compiled" \

6  --field "Pages:12:inline"
7
8# Attach the full report
9cord file 123456789 ./weekly-report.pdf "Full report attached"

Confirmation flow

bash
1# Ask for confirmation
2cord buttons 123456789 "Delete all archived items older than 30 days?" \
3  --button label="Yes, Delete" id="confirm-delete" style="danger" reply="Deleting..." \
4  --button label="Cancel" id="cancel-delete" style="secondary" reply="Cancelled"

Auto-Complete Behavior

When a user adds a ✅ reaction to the last message in a thread, Cord automatically:

1. Detects the reaction
2. Updates the thread starter message to "✅ Done"

This provides a quick way for users to signal "conversation complete" without explicit commands.
