Treat them as runbooks and include them in your troubleshooting guide (or oncall guide). Small snippets can be in a wiki or in the docs, bigger scripts preferably in a repo that everyone can run. If they provide useful info that's not just for emergencies or troubleshooting, maybe let them run via cronjob and expose the results in a dashboard or a dedicated internal "status web page".
