Programming languages: Python, TypeScript, JavaScript, Rust, Go, Java, C#, C++, PHP, Ruby and more. Skills here set language idioms, linters and formatters, type checking, builds and package managers. The most useful ones lock in decisions specific to your project: language version, type strictness, banned constructs. The model already knows generic style advice. If a skill contradicts your linter, the agent gets two rule sets and will flip between them.
