Rust FFI skill for C interoperability. Use when calling C libraries from Rust, generating Rust bindings with bindgen, exporting Rust functions to C with cbindgen, writing safe wrappers around unsafe FFI, or linking system and vendor libraries. Activates on queries about bindgen, cbindgen, extern "C", unsafe FFI, Rust C bindings, linking C from Rust, or sys crates.
Master Rust 1.75+ with modern async patterns, advanced type system features, and production-ready systems programming. Expert in the latest Rust ecosystem including Tokio, axum, and cutting-edge crates. Use PROACTIVELY for Rust development, performance optimization, or systems programming.
IC-specific security patterns for canister development in Motoko and Rust. Covers access control, anonymous principal rejection, reentrancy prevention (CallerGuard pattern), async safety (saga pattern), callback trap handling, cycle drain protection, and safe upgrade patterns. Use when writing or modifying any canister that modifies state, handles tokens, makes inter-canister calls, or implements access control.

Rust build time optimization skill for reducing slow compilation. Use when using cargo-timings to profile builds, configuring sccache for Rust, using the Cranelift backend, splitting workspaces for parallelism, choosing between thin LTO and fat LTO, or using the mold linker with Rust. Activates on queries about slow Rust compilation, cargo-timings, sccache Rust, cranelift backend, Rust workspace splitting, LTO tradeoffs, or mold linker with Rust.
Reviews axum web framework code for routing patterns, extractor usage, middleware, state management, and error handling. Use when reviewing Rust code that uses axum, tower, or hyper for HTTP services. Covers axum 0.7+ patterns including State, Path, Query, Json extractors.
Fix the findings recorded in a crate issue file one at a time, with failing test first, minimal fix second, full crate verification third, and issue-file status updates after each successful fix. Use for Rust crate issue lists that already exist and need disciplined sequential repair.
