What problem does it solve?

This Skill enhances API security and robustness by validating string path parameters directly at the routing layer, preventing invalid inputs from reaching controller logic.

Core Features & Use Cases

• Input Validation: Ensures path parameters conform to a specified pattern and length.
• Reduced Boilerplate: Eliminates the need for manual validation within controller actions.
• Automatic 404 Responses: Non-matching routes are automatically rejected with a 404 status code.
• Use Case: Protect your API endpoints by ensuring that an id parameter in a route like /items/{id:myConstraint} only accepts alphanumeric characters, periods, underscores, and hyphens, up to 100 characters.

Quick Start

Add a route constraint named 'myConstraint' that validates string path parameters against a pattern of alphanumeric characters, periods, underscores, and hyphens, with a maximum length of 100 characters.
