## About

# preset-embedded-rls

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

## Always

- Auth and conventions come from `preset-api` (JWT exchange, base URLs, Rison); resolve the workspace hostname through the Management API when it is not already known. Consult 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.

## Decision Rules

- Classify embedded RLS review as plan-only safety work.
- Identify tenant and user filter safety issues.
- Require approval before clauses are used in token claims.
- Avoid mutating embedded RLS configuration.

## Workflow Order

1. Inspect embedded RLS clauses.
2. Flag unsafe tenant and user filters.
3. Summarize approval requirements.
4. Stop before using clauses in tokens.
