Open an issue on the plugin repository: github.com/TeamManagementPlugin/claude-plugin/issues. Include your Claude Code version, the protocol you were running, and what you expected versus what happened — that is enough for us to act on it.

There is no contact email and no support inbox: the project domain does not send or receive mail, and issues are handled in public so the answer helps the next person too. For anything security-sensitive, use the repository’s private vulnerability reporting on GitHub rather than a public issue.
