Usage Pattern
# 1. Check if a user exists
RESULT=$(npx tsx .claude/tools/slack-cc/src/index.ts list-members --filter zeeshan)
# 2. Send notification
npx tsx .claude/tools/slack-cc/src/index.ts send-dm zeeshan "DIS-307 design polish is complete!"
# 3. Or post to channel
npx tsx .claude/tools/slack-cc/src/index.ts send-message prototype-v2-updates "New feature deployed! See DIS-308"
Error Handling
Slack updates are informational, not blocking. If sending fails:
- Warn and continue
- Log error for debugging
- Don't block the primary workflow
RESULT=$(npx tsx .claude/tools/slack-cc/src/index.ts send-message design-studio "Update" 2>&1)
if echo "$RESULT" | grep -q '"success":true'; then
echo "Message sent"
else
echo "Warning: Slack notification failed. Continuing..."
