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):

  1. Call slack_get_channel_history with limit of 20 messages
  2. 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

OptionDescription
Create taskTurn a message into a task
ReplyDraft a response
Mark readContinue 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:

  1. Checks Slack for new activity
  2. "You have 5 new messages across 2 channels..."
  3. Summarizes key items
  4. Offers to create tasks from actionable messages
  5. 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

When to Use

Use this skill when the task directly matches the workflow described above.

When Not to Use

Do not use this skill when the request is unrelated, low-stakes, or better handled by a simpler direct response.
