The Rust Developer skill provides comprehensive guidance for writing, reviewing, and debugging Rust code, distilled from six months of code reviews on the Catalyst project. It addresses common pitfalls, enforces idiomatic Rust practices, and promotes safe, performant code. By following these guidelines, developers can avoid frequent errors, handle file I/O safely, maintain type safety, and optimize their Rust applications effectively. The skill is particularly valuable for teams seeking consistency across projects and for individuals aiming to deepen their understanding of Rust development patterns.

This skill includes a structured set of resources, from quick-reference checklists summarizing over 20 key rules to deep-dive guides on fundamentals, error handling, file I/O safety, and intermediate Rust patterns. Each resource provides actionable examples, recommended patterns, and best practices, covering topics such as ownership management, concurrent state handling, parameterized queries, CLI user feedback, and tracing/logging setup. The materials also highlight common footguns and provide explicit guidance for testing error paths and optimizing performance.

Rust Developer is suitable for both new and experienced developers working on CLI tools, hooks, or production code. It is useful when writing or modifying `.rs` files, debugging compiler errors, reviewing pull requests, or exploring idiomatic Rust patterns. Target users include developers implementing error handling, type safety, and performance optimizations, as well as those seeking structured learning paths and reference materials for consistent, high-quality Rust code.
