Slack Message Check

Check Slack channels for important messages and summarize activity.

Instructions

Step 1: List Relevant Channels

Call slack_list_channels to see available channels.

Step 2: Check Priority Channels

For each important channel (determined by user preferences or channel activity):

Call slack_get_channel_history with limit of 20 messages
Filter for messages since last check

Step 3: Summarize Activity

Present findings to user:

Slack activity since yesterday:

**#general** (3 new messages)
- @alice mentioned the deployment schedule

**#engineering** (12 new messages)  
- Discussion about API changes
- @bob asked for review on PR #234

**DMs** (2 unread)
- @carol: Question about meeting time

Step 4: Offer Actions

Option	Description
Create task	Turn a message into a task
Reply	Draft a response
Mark read	Continue without action

Step 5: Continue Daily Flow

After Slack check, continue with normal planning workflow.

Example Flow

User: "What should I work on today?"

Agent:

Checks Slack for new activity
"You have 5 new messages across 2 channels..."
Summarizes key items
Offers to create tasks from actionable messages
Continues with task planning

Notes

Focus on actionable messages, not all activity
Prioritize DMs and mentions over general channel noise
Respect user's channel preferences if configured
