/rename generates unusable /resume command

Bug Description

After using /rename to give a session a display name, Claude Code prints:

Resume this session with:
claude --resume "Agents and Skills audit"

But running that exact command returns:

No conversations found to resume.

The same failure occurs with both claude --resume "name" from the shell and /resume "name" from within Claude Code.

Steps to Reproduce

1. Start a Claude Code session
2. Run /rename Agents and Skills audit
3. Session header updates to show the new name
4. Terminal prints Resume this session with: claude --resume "Agents and Skills audit"
5. Exit the session
6. Run claude --resume "Agents and Skills audit"
7. Result: No conversations found to resume.

Expected Behavior

Either:

• /resume should work with display names set by /rename, OR
• The "Resume this session with:" line should show the actual session ID, not the display name

Actual Behavior

The generated resume command does not work. The tool instructs the user to run a command that fails.

Environment

• Claude Code v2.1.100
• Model: claude-sonnet-4-6
• Platform: macOS (darwin)
