Memory write transparency: show file path and diff content

Problem

When Claude writes to memory, the UI currently shows a collapsed summary like:

Recalled 1 memory, wrote 1 memory (ctrl+o to expand)

This lacks critical information for user oversight:

1. Which file was written to — global memory (~/.claude/CLAUDE.md) vs project memory (./CLAUDE.md) vs other paths are meaningfully different, and Claude sometimes picks the wrong level
2. What was actually written — the exact diff/content, not just "wrote 1 memory"

Why this matters

Claude isn't perfect at:

• Choosing the right memory file (global vs project-local)
• Formulating memory entries exactly as the user intends
• Understanding what scope a piece of information belongs at

Without seeing the actual write, users can't catch and correct these mistakes in real-time.

Request

Add a configuration option (or make it the default) to show:

1. The full file path of each memory file being written
2. The diff or content of what's being written

This could be behind a verbose/transparency flag for users who want it, but the information should be accessible without having to manually check files after the fact.

Environment

• Claude Code version: 2.1.31
