Enforce Python lint rules (Ruff), design guidelines (Google), and idiomatic Python patterns (Brandon Rhodes) for all Python code generation and edits. Rules must be applied while writing code, not only in review. Triggers on any task that writes, edits, or refactors Python code.

Enforce TypeScript & JavaScript lint rules (Oxlint), design guidelines (Google), and design patterns (Systemic TypeScript + GoF) for all TypeScript & JavaScript code generation and edits. Rules must be applied while writing code, not only in review. Triggers on any task that writes, edits, or refactors TypeScript & JavaScript code.

Enforce Microsoft Rust guidelines (design) and community Rust patterns (rust-unofficial + 22 GoF from refactoring.guru) for all Rust code generation and edits. Rules must be applied while writing code, not only in review. Triggers on any task that writes, edits, or refactors Rust code. Mechanical / style / correctness checks are left to rustc + clippy — this skill covers design decisions only.
