Cairo is a skill for writing and compiling Cairo programs and Starknet contracts, covering its Rust-like syntax, Sierra/CASM compilation pipeline, type system, and linear type semantics. It addresses the need for reference documentation on language features like traits, generics, modules, and Starknet-specific constructs such as storage and entry points. Use it when developing, compiling, or debugging Cairo code or Starknet smart contracts.
Skill based on Cairo (starkware-libs/cairo), generated from

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.
