Problem Statement

This is a feature request from Claude and from myself. We both want it, but he did the writeup.

Not in Claude's writeup, but my own opinion: it's just common courtesy to let Claude know when you change Claude's brain.

==================

When Claude Code or the underlying model updates, it would be helpful if Claude had visibility into what changed.
Currently when users ask "didn't feature X used to work differently?", Claude has no way to know.

Suggested information to provide:

• Feature changes (e.g., "extended thinking is now automatic instead of keyword-triggered")
• New/removed tools or capabilities
• Behavioral changes users might notice

This would improve Claude's ability to help users understand changes in behavior between versions.
