rust-review is an agent skill for reviewing workerd Rust code with CXX FFI, unsafe, JSG, and error handling checklists.
About
The rust-review skill provides Rust code review guidance for Cloudflare workerd source under src/rust/. It covers CXX FFI safety, unsafe code patterns, JSG resource conventions, error handling, and a review checklist adapted from existing C++ review skills. Reviewers must always use the docs/reference/rust-review-checklist.md file when evaluating Rust changes rather than improvising criteria. The skill loads when reviewing Rust pull requests or diffs in the workerd repository where memory safety across the CXX boundary, JSG lifecycle rules, and workerd-specific error propagation matter. It complements C++ review skills by translating the same rigor to Rust modules that interface with the JavaScript runtime and V8 bindings. Use when a contributor submits Rust changes to workerd, when unsafe blocks need audit, or when FFI bindings between Rust and C++ require checklist-driven review before merge to production runtime code.
- Mandates docs/reference/rust-review-checklist.md for every Rust review.
- Covers CXX FFI safety and unsafe code pattern review.
- Applies JSG resource conventions specific to workerd Rust modules.
- Includes error handling review adapted from C++ review skills.
- Scoped to Rust code under workerd src/rust/ directory.
