Skill based on Cairo (starkware-libs/cairo), generated from
sources/cairo. Doc path:sources/cairo/docs/reference/src/components/cairo/modules/.
Cairo is a Turing-complete language for provable programs (Starknet, general computation). It uses a Rust-like syntax, Sierra as an intermediate representation, and compiles to CASM. Use this skill for writing and compiling Cairo programs and Starknet contracts, and for understanding types, traits, and linear semantics.
