Develop OPA Rego policies by applying best practices for clarity and performance, using helper rules over complex comprehensions and properly handling undefined values to ensure secure and efficient policy enforcement.

You can validate Rego policies by integrating with `opa check` to catch errors and `regal lint` to identify style violations early, ensuring your code adheres to established best practices.

Yes, you can create OPA Rego policies to enforce Kubernetes deployment configurations, such as requiring resource limits to be defined for all deployments within your cluster.

A common pitfall in Rego is mishandling undefined values; you should prefer using helper rules over complex comprehensions to manage variable evaluation safely and maintain policy clarity.

The best way to structure maintainable Open Policy Agent rules is to follow conventions for naming, rule design, and variable usage, ensuring your policy code remains clear and efficient.
