# preset-embedded-rls

Use before guest-token creation when embedded viewers need row-level security.

## Always

- Use `preset-api`, `preset-workspaces`, and metadata skills only when column validation is required.
- Do not invent tenant identifiers, filters, dataset columns, or access rules.
- Treat RLS clauses as permission controls that can leak or hide customer data.
- Confirm every clause and intended viewer population before token creation.
- Do not validate with broad data-returning queries unless the user approves target and limit.
