Identifies and remediates null pointer dereference risks and unhandled nullable types in PHP applications.
This skill empowers Claude to perform deep static analysis on PHP codebases to identify potential 'Billion Dollar Mistake' scenarios. It specifically targets common PHP pitfalls such as accessing properties on null objects, missing null coalescing operators, and risky chained method calls. By analyzing patterns in Doctrine, Eloquent, and standard PHP collections, it provides actionable fixes to prevent runtime crashes and improve code stability, ensuring that every nullable return type is safely handled before access.
