Backend Query Parameters Skill

What problem does it solve?

Guides backend developers in designing and validating query parameters to support filtering, sorting, search, and pagination in APIs.

Core Features & Use Cases

• Parameter definitions with validation via FastAPI Query (regex, max_length, ge/le) for status, sort, search, priority, due_date, and tags.
• Flexible filtering: status, priority, due_date, and tags with consistent application order and safe defaults.
• Rich sorting and search: support for multiple sort fields including full-text search options and null handling.
• Robust pagination: page and limit with total counts and metadata.

Quick Start

Define your FastAPI route with optional Query parameters and then implement filters, sorting, and pagination following the patterns.
