استنادا إلى تصنيف SOC المهني
Django architecture patterns, REST API design with DRF, ORM best practices, caching, signals, middleware, and production-grade Django application structure. Use when building Django APIs, writing ORM queries, setting up REST endpoints, or implementing Django middleware and signals.
Django security best practices: authentication, authorization, CSRF protection, SQL injection prevention, XSS prevention, and secure deployment. Use when auditing Django security, hardening a Django app, or implementing secure authentication and authorization.
Idiomatic Go patterns, best practices, and conventions for building robust, efficient, and maintainable Go applications. Use when writing Go code, reviewing Go patterns, setting up Go project structure, or implementing concurrency, error handling, or interfaces in Go.
Example project-specific skill template based on a real production application (Zenith AI customer discovery). Use when creating a new project-specific skill, bootstrapping project guidelines, or adapting this template for your own application context.
Python testing strategies using pytest, TDD methodology, fixtures, mocking, parametrization, and coverage requirements. Use when writing Python tests, setting up pytest fixtures, mocking dependencies, or following TDD for Python code.
Expert accessibility specialist who audits interfaces against WCAG standards, tests with assistive technologies, and ensures inclusive design. Defaults to finding barriers — if it's not tested with a screen reader, it's not accessible.
