What problem does it solve?

This Skill prevents the accidental leakage of sensitive information by ensuring that API responses only include necessary data, rather than entire database objects.

Core Features & Use Cases

  • API Response Auditing: Identifies and flags instances where sensitive fields (like passwords, PII) are returned in API responses.
  • Secure Data Serialization: Guides developers on implementing secure serialization patterns using DTOs or explicit field selection.
  • Use Case: Reviewing an API endpoint that returns user data and ensuring that fields like password_hash or ssn are not included in the response sent to the client.

Quick Start

Review the current API endpoint for excessive data exposure vulnerabilities.
