System Documentation

What problem does it solve?

This Skill helps developers diagnose and resolve Content Security Policy (CSP) and Subresource Integrity (SRI) violations within the jmrp.io project, ensuring enhanced web security.

Core Features & Use Cases

  • CSP Violation Analysis: Identifies common CSP issues like inline scripts/styles and data URIs.
  • SRI Hash Verification: Checks for missing or incorrect SRI integrity hashes on external resources.
  • Configuration Debugging: Assists in understanding and verifying the project's nonce-based CSP strategy and Nginx header configurations.
  • Use Case: If your website is suddenly breaking due to security headers, this Skill can pinpoint whether the issue lies with inline styles, missing script nonces, or incorrect SRI hashes on your CSS/JS files.

Quick Start

Run the security tests to verify CSP and SRI compliance on all pages.
