SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill audits multi-tenant data isolation, checking for tenant model fit, missing or unenforced tenant scoping, and cross-tenant leak risks.

Core Features & Use Cases

  • Tenant Model Fit: Assess whether the tenant model (shared rows vs schema vs database) aligns with the isolation requirements.
  • Tenant Scoping: Verify that tenant-owned tables have appropriate scoping columns and constraints.
  • Indexing and Keys: Check that indexes and primary keys lead with tenant_id for proper pruning.
  • Cross-Tenant Constraints: Ensure uniqueness or foreign key constraints do not allow cross-tenant data leakage.
  • Use Case: For a company with a multi-tenant database, this Skill can identify potential data leaks and performance issues, helping maintain data integrity and system performance.

Quick Start

Run the db-multitenancy skill to audit your multi-tenant database schema.

FAQPage Schema
How do I audit my multi-tenant database schema for data isolation issues?▼

To audit your multi-tenant database schema for data isolation, you must verify tenant model fit, check for missing tenant scoping, and review cross-tenant constraints to identify potential data leaks and ensure proper isolation.

What is a cross-tenant data leak risk in a shared database?▼

A cross-tenant data leak risk in a shared database occurs when uniqueness or foreign key constraints fail to enforce tenant boundaries, allowing unintended data access. It also arises from missing or unenforced tenant scoping columns on shared rows.

How do I check if my indexes support tenant-based query performance?▼

To check if your indexes support tenant-based query performance, verify that primary keys and indexes lead with the tenant_id column. Proper tenant_id leading indexes ensure effective query pruning and maintain system performance.

Does the multi-tenancy audit require a specific database platform?▼

The multi-tenancy audit requires PostgreSQL specifically. You must also have direct access to the database schema so the audit can accurately assess tenant model fit, scoping, and cross-tenant constraints.

When do I need to assess my tenant model fit for data isolation?▼

You need to assess your tenant model fit for data isolation when evaluating whether your current architecture—shared rows, shared schema, or separate databases—aligns with your strict isolation requirements and prevents cross-tenant leak risks.
