Choosing the Right Command

Assembly Patterns

Notification with follow-up options

# Send the notification
cord embed 123456789 "Build failed on main branch" \
  --title "CI Alert" \
  --color red \
  --field "Error:Test suite timeout" \
  --field "Commit:abc1234:inline"

# Offer actions
cord buttons 123456789 "What would you like to do?" \
  --button label="View Logs" id="view-logs" style="primary" reply="Fetching logs..." \
  --button label="Retry Build" id="retry" style="success" webhook="http://ci/retry" \
  --button label="Ignore" id="ignore" style="secondary" reply="Acknowledged"

Progress updates

# Start with typing indicator
cord typing 123456789

# Send initial status message
MSGID=$(cord send 123456789 "🤖 Processing..." | grep -o '[0-9]*$')

# Update state as work progresses
cord state 123456789 $MSGID searching
cord state 123456789 $MSGID writing
cord state 123456789 $MSGID done

Or with custom progress:

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

Report delivery

# Send summary embed
cord embed 123456789 "Weekly metrics compiled" \
  --title "Weekly Report Ready" \
  --color blue \
  --field "Period:Jan 15-21:inline" \
  --field "Pages:12:inline"

# Attach the full report
cord file 123456789 ./weekly-report.pdf "Full report attached"

Confirmation flow

# Ask for confirmation
cord buttons 123456789 "Delete all archived items older than 30 days?" \
  --button label="Yes, Delete" id="confirm-delete" style="danger" reply="Deleting..." \
  --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.

HTTP API

For advanced use cases (webhooks, external scripts), see [HTTP-API.md](./HTTP-API.md).
