DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.227

Tip pointing Slack MCP users at Claude Tag

You'll notice
Useful2 Signal2
MCP not in their notes

If you use a Slack MCP server, a startup tip points you at the Slack app instead.

/install-slack-app
What

A new startup tip appears when the session has an MCP server whose name contains "slack" and the Slack app has never been installed: "Using a Slack MCP? With Claude Tag you can @Claude directly in Slack, run /install-slack-app or share claude.com/product/tag with your org owner". It has a cooldown of 10 sessions.

Details
  • tip id is install-slack-app-mcp
  • suppressed once the Slack app has been installed
Evidence

install-slack-app-mcp

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
