Broken commands are left out of the slash-command list
Claude Code now skips commands with a missing or invalid name, and MCP commands with overlong names, when listing slash commands

What
When Claude Code builds the list of slash commands, the commands you type after /, it now leaves some out and logs "Command not listed":
- Commands whose name or display name is not text
- MCP commands whose name or alias is over a length limit
MCP commands come from MCP servers, outside programs that add tools and commands to Claude Code.
Why
One badly made plugin or MCP command no longer breaks the whole slash-command list.
