Explain Cairo closures, syntax, capture rules, type inference, and Fn traits; use when a request involves anonymous functions or passing behavior as a parameter in Cairo.

Explain how components are expanded under the hood, including HasComponent and ComponentState; use when a request involves debugging or understanding generated component code in Cairo.

Explain how to build custom data structures in Cairo using structs, traits, and dictionaries; use when a request involves implementing mutable collections (like a vector) or handling Destruct/Drop with Felt252Dict.

Explain Cairo generic data types and syntax for generic functions, structs, enums, methods, and impls; use when a request involves type parameters or generic signatures in Cairo.

Explain Cairo declarative macros, macro hygiene, and macro vs function tradeoffs; use when a request involves writing or understanding `macro` definitions in Cairo.

Explain Cairo method syntax, traits/impl blocks, `self` parameter forms, and associated functions; use when a request involves defining or calling methods on structs in Cairo.

Explain Cairo modules, `mod` declarations, privacy, and scope control; use when a request involves organizing code into modules or resolving visibility errors in Cairo.

Explain Cairo unrecoverable errors, `panic`, `panic!`, `panic_with_felt252`, `nopanic`, and `panic_with`; use when a request involves panics or panic annotations in Cairo.

Explain Cairo operator overloading using core::ops traits like Add; use when a request involves redefining operators for custom types in Cairo.

Explain Cairo ownership, moves, Copy/Drop/Destruct traits, and scope-based destruction; use when a request involves use-after-move errors, copying values, or ownership semantics in Cairo.

Explain Cairo printing and formatting with print!/println!/format!, Display/Debug traits, and Formatter helpers; use when a request involves output formatting or printing custom types in Cairo.

Explain Cairo variable bindings, immutability, `mut`, constants, and shadowing; use when a request involves variable declaration, reassignment errors, changing types via shadowing, or defining constants in Cairo.
