Core Rust engineering. Use for implementation, debugging, review, compiler errors, ownership and lifetimes, traits and generics, async and concurrency, typed errors, Cargo and MSRV, crate choice, tests, performance, unsafe and security. Excludes focused product surfaces owned by narrower Rust skills.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Rust Expert Use this as the default Rust engineering router. Inspect the repo first, load only the references needed for the task, then use compiler/test feedback as design evidence. ## Operating Model 1. Read the local guidance and manifests first: `AGENTS.md`, `Cargo.toml`, `Cargo.lock`, `rust-toolchain.toml`, `.cargo/config.toml`, CI, `justfile`, `mise.toml`, and nearby tests. 2. Classify the task before editing: compile failure, implementation, review, refactor, dependency, public API, release, performance, or security. 3. Fix the root cause. Avoid silencing Rust with reflexive `.clone()`, `Arc<Mutex<_>>`, broad trait bounds, `unwrap`, or `unsafe`. 4. Use repo-native gates first. When command surface is unclear, run `scripts/discover-rust-gates.mjs <repo-root>`. 5. Research current docs/source when facts can drift: dependency additions or upgrades, version-sensitive APIs, Tauri/plugin support, public API/release decisions, security, unsafe/FFI, or novel crates. ## Domain Routing | Signal | Prefer | | --- | --- | | Command-line app, subcommands, flags, config precedence, JSON/stdout contracts | `rust-cli-clap` | …

How to install
mdr add bjornmelin/dev-skills/rust-expert@sha256:47fb8aabb50bd750The line at the top of this page pins the label git:20260729.efe35f4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
