What problem does it solve?

Core Features & Use Cases

  • Secure HTML Sanitization: Uses the Ammonia crate to clean HTML content based on configurable whitelists for tags and attributes.
  • URL Validation: Ensures that links within the HTML use only safe schemes (http, https, mailto, ftp).
  • Use Case: When displaying user-generated comments or forum posts that may contain HTML, use this Skill to clean the input before rendering it to prevent malicious code execution.
