Consider expanding set of tips for Copilot CLI and Claude Agent

[bamurtaugh]

I only see this Mermaid tip available for Copilot CLI or Claude Agent sessions (and there are no others that I can navigate through):

We should consider other tips we'd want to surface to users for these sessions.

Is there an API for chat session providers to provide tips @meganrogge ?
