OSINT templates are available for conducting user enumeration across many websites. By utilizing the flag to input a user, Nuclei can verify the user's existence across all websites listed in the templates and report any instances of success.
The templates within the `osint` directory are **self-contained** and do NOT require URLs as input because the OSINT templates have pre-defined static URLs. Each template in this directory expects the user(name), email, or phone number or list of it to be supplied as input using the `V`/`var` flag through the Nuclei engine.
