Use Cases

Action Use Cases

When you ask CORE to perform Slack tasks, it uses MCP tools to execute your requests:

Send Team Updates

Scenario: Broadcast important updates to specific channels

"Send a message to the #announcements channel saying 'New release v2.0 is live!'
then post the same message to #product-team"

The agent will use slack_send_message to deliver updates to multiple channels, keeping teams synchronized on important news.

Search Conversation History

Scenario: Find past discussions and decisions

"Search for all messages mentioning 'database migration' from the last week
and show me who was involved in those conversations"

The agent will use slack_search_messages to find relevant discussions and can follow up with slack_get_message to retrieve full context.

Manage Channels

Scenario: Create and organize project channels

"Create a new private channel called 'project-alpha',
add team members john, jane, and mike to it,
and set the channel topic to 'Alpha project planning and tracking'"

The agent will:

Use slack_create_channel to create the private channel
Use slack_invite_to_channel to add team members
Use slack_set_channel_topic to set the channel description

React to Messages

Scenario: Acknowledge messages without creating noise

"Add a thumbsup reaction to the latest message from @sarah in #general,
and add a heart reaction to the announcement in #announcements"

The agent will use slack_add_reaction to provide quick acknowledgments and emoji responses.

Monitor Important Channels

Scenario: Stay updated on critical conversations

"Check #critical-alerts for any unread messages
and get a list of the last 10 messages from #security-updates"

The agent will use slack_get_unread and slack_list_messages to keep you informed on critical topics without missing important updates.

Proactive Use Cases

With webhooks enabled, CORE monitors Slack 24/7 and acts automatically based on your instructions:

Auto-Capture Customer Feedback

Trigger: New message in #sales-feedback channelAutomated Action: Extract insights and save to CORE memory

"Whenever a message is posted in #sales-feedback,
extract the key insights and save them to my memory
with the label 'customer-feedback'"

CORE monitors the channel and automatically captures feedback without manual intervention. You can later search and analyze patterns across all feedback.

Release Notifications

Trigger: New message in #deployments channel containing “released”Automated Action: Send summary notification via WhatsApp

"When a release is posted in #deployments,
send me a WhatsApp message with a brief summary
of what was released"

Stay informed on releases without monitoring Slack. CORE watches for deployment messages and notifies you on your preferred channel.

Smart Message Routing

Trigger: Direct message from specific users (e.g., your manager)Automated Action: Cross-post to WhatsApp with priority flag

"If I receive a DM from @manager on Slack,
immediately forward it to me on WhatsApp
and mark it as urgent"

Never miss critical messages. CORE routes important communications to where you’ll see them fastest.

Team Onboarding

Trigger: New user joins #engineering channelAutomated Action: Send onboarding resources and log to memory

"When someone joins #engineering,
send them our onboarding doc link
and add their name to the team members list in my memory"

Automate team onboarding. CORE welcomes new members and keeps your team roster updated automatically.

Urgent Alert Escalation

Trigger: Message contains keywords like “urgent”, “critical”, or “down”Automated Action: Notify across channels and create task

"If anyone posts a message with 'production down' in #alerts,
notify me on WhatsApp immediately
and create a high-priority task in Linear"

CORE monitors for critical keywords and escalates issues across your entire workflow automatically.
