Document Cairo language quirks, gotchas, and idiomatic workarounds; use when encountering unexpected compilation errors or behaviors in Cairo that differ from Rust.
Guide implementing custom numeric types in Cairo with invariant enforcement, overflow safety, and standard trait implementations; use when implementing fixed-point, signed integers, or other numeric primitives.
Explain how to write and run Cairo tests, including `#[test]`, assert macros, `#[should_panic]`, `#[ignore]`, and `#[available_gas]`; use when a request involves writing or running unit tests in Cairo.
Explain Cairo Array usage, ArrayTrait methods, array! macro, Span, and array read/write constraints; use when a request involves creating, updating, reading, or passing arrays in Cairo.
Explain Cairo associated items (functions, types, constants, implementations) in traits and impls; use when a request involves associated types, constants, or clarifying trait item placement in Cairo.
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 panics work in Cairo, how to trigger them, and how to constrain panic behavior.
references/panic.md before answering.nopanic requirements when a caller demands panic-free code.panic for array-based errors, panic_with_felt252 for a single felt, and panic! for strings.#[panic_with(...)] for wrapper functions that panic on None or Err.nopanic mean?"None?"
