Problem Statement

Current behavior:
When a tool call is denied, the conversation shows "Tool Use Rejected" with no context about the original prompt.

Expected behavior:
The user's actual prompt text should remain visible when a tool is rejected, keeping the conversation readable.

Proposed Solution

Suggested:
A setting like showRejectedPrompts: true in ~/.claude/settings.json to control this behavior.
