Catch Up on Slack Since Yesterday

For an operator who was heads-down or off and wants a consolidated read of every channel they're in over a 24–48h window.

THE GRIND

Lost in the thread

Here's what doing this by hand looks like today — and why it doesn't scale.

Coming back from a day off means scrolling a dozen channels

Important decisions get buried in long threads

You end up asking 'what did I miss?' in five different DMs

Composio collapses all of this into one prompt — here's what that looks like.

THE FLOW
7 steps · 1 toolkit

Your agent runs it end-to-end.

  1. 01
    List channels the user is a member of

  3. 03
    Drop channels with fewer than the minimum message count
  4. 04
    For each remaining channelCluster messages into distinct threads/topics. Summarize each thread in one line with the lead participant and message count.
  5. 05
    Flag any message that @-mentions the current user or contains urgent keywordsBroken, blocker, down, p0, p1, incident. These go to a "⚠️ For you" section at the top.
  6. 06
    Build a permalink for each notable thread

  7. 07
    Return the recap, focus channels first, then by volume
THE PAYOFF

Back in the loop in seconds

One prompt replaces an hour of scrolling with a channel-by-channel recap you can scan over coffee.

Paste this into Claude, Cursor, or Codex. It'll install the CLI, connect your apps, and run the task — end to end.
