The prompt

I missed messages in a Slack channel and need to catch up.

Channel: [PASTE CHANNEL NAME e.g. #team-updates]
Time window: last 24 hours (change if I specify otherwise)

Summarize:
- Key decisions made
- Action items and who owns them
- Questions directed at me (if any)
- Links or docs I should open

Skip banter and reactions. Under 300 words. Bullet points.
Do not post anything to Slack — summarize only.

Paste into Claude Desktop. Claude will use your connected apps: Slack.

Expected outcome

Troubleshooting

I can't find Connectors in Claude Desktop

Cause

You may be using the website instead of the desktop app.

Solution

Download Claude Desktop from claude.ai/download. Open Settings → Connectors or Integrations.

An app won't connect

Cause

Wrong account or company requires IT approval.

Solution

Reconnect with your work account. If blocked, paste the relevant text into Claude and say "Use only what I pasted."

The output is too long or vague

Cause

The prompt needs a tighter focus.

Solution

Reply: "Shorter — bullet points only" or "Top 3 items only."

Claude can't read the channel

Cause

Private channel or you're not a member.

Solution

Join the channel in Slack first, or ask a teammate to export key messages and paste them.
