Claude Code cannot detect new commands or deleted commands

Steps to produce the issue

• Open Claude Code in a terminal
• Add a new command to ~/.claude/commands/mycommand.md
• Enter /. Claude Code doesn't suggest the new command

• Now, /exit then open Claude Code again. New command is detected.

• Now, delete the file mycommand.md. Claude Code still suggests the deleted command.

Expectation

Option 1: Claude Code should detect new/deleted commands automatically.

Option 2: Provide a way to tell Claude Code to refresh/reindex to detect new/deleted commands.

Additional

I am not sure if this is also the issue for other files. For example, if we copy and delete files directly in agents directory without using /agents. In this case, please also fix it.
