/clear deletes chat history permanently

I lost multiple days of conversation history in a long-running coding session because /clear wiped the chat without recovery option.

What happened

• I typed /clear because Claude told me that this will clear his session
• The entire visible chat history was deleted immediately and permanently
• There is no undo, no recovery, no archive

Why this is a serious problem

• Claude told me this will clear the session and not the complete chat
• Long sessions (multi-day) contain decisions, explanations, and context that cannot easily be reconstructed
• No warning. No "are you sure?". No backup. Just gone.
• Additionally: the system automatically compresses/summarizes long sessions without any warning — this also causes visible history loss and looks identical to a /clear from the user's perspective

What should happen instead

• Keep history visible but reset Claude's context separately
• Auto-archive before clearing
• Show a clear warning explaining EXACTLY what /clear does (deletes the entire chat, not just Claude's context)
• Same warning for auto-compression events

This is a destructive, irreversible action that is triggered too easily.
