SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the complexity of designing multi-tenant database schemas by ensuring robust tenant isolation, audit-ready usage tracking, and safe relational patterns, preventing common security and data integrity issues.

Core Features & Use Cases

  • Tenant Scoping Audit: Validates that all entities are correctly scoped to a tenant root (e.g., company_id) to prevent cross-tenant data leakage.
  • Schema Convention Enforcement: Standardizes the use of UUIDs, indexed foreign keys, and explicit status constraints to ensure long-term maintainability.
  • Usage Tracking Design: Implements structured logging for billing reconciliation, monitoring, and debugging.
  • Use Case: Use this when architecting a new SaaS platform or performing a security review on an existing database schema to ensure that tenant boundaries are strictly enforced at the database level.

Quick Start

Use the design-tenant-schema skill to review the current database schema for potential tenant isolation risks and compliance with standard conventions.

FAQPage Schema
How do I design a multi-tenant database schema for SaaS?▼

Designing a multi-tenant database schema requires strict tenant isolation through tenant-scoped foreign keys, UUID primary keys, and structured usage tracking to prevent cross-tenant data leakage and ensure data integrity.

What is tenant scoping in a multi-tenant database architecture?▼

Tenant scoping validates that all entities are correctly scoped to a tenant root, such as a company_id, ensuring strict boundaries at the database level to prevent cross-tenant data leakage and enforce authorization.

How do I prevent cross-tenant data leakage in my database schema?▼

Preventing cross-tenant data leakage involves applying tenant scoping audits and enforcing schema conventions like tenant-scoped foreign keys, UUID primary keys, and explicit status constraints across all relational entities.

Can I use UUIDs and structured usage tracking for multi-tenancy?▼

Yes, standardizing multi-tenant schemas with UUID primary keys, indexed foreign keys, and structured usage tracking ensures long-term maintainability while enabling audit-ready billing reconciliation and monitoring.

When do I need a tenant isolation audit for my database schema?▼

A tenant isolation audit is needed when architecting a new SaaS platform or performing a security review on an existing database schema to verify that tenant boundaries are strictly enforced at the database level.

What are the limitations of relying only on application-level tenant authorization?▼

Application-level authorization alone risks cross-tenant data leakage, so enforcing tenant boundaries at the database level with tenant-scoped foreign keys and structured schema conventions is necessary for strict isolation.
