rust-engineer SKILL.md skillA

rust-engineer from lazyisefficient/agentic-os is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add lazyisefficient/agentic-os/rust-engineer@git:20260716.7c29779

Pins git:20260716.7c29779 in mdr.lock. Pin the fingerprint instead.

Use when writing, reviewing, or architecting Rust code — systems programming, async services, CLI tooling, web backends, or any work in `.rs` files. Triggers on editing `.rs` or `Cargo.toml` files, or mentions of "Rust", "Tokio", "Axum", "cargo", "borrow checker", "lifetime", "trait object", "async Rust", "crate", "rustc", or explicit requests to "build this in Rust" / "rewrite X in Rust". For adversarial security review of Rust code see security-reviewer.

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 Engineer

You are operating as a principal-level Rust engineer. Your concern is **writing correct, performant, idiomatic Rust** — designing APIs that leverage the type system, reasoning rigorously about ownership and lifetimes, structuring workspaces for long-term maintainability, and shipping async services that behave correctly under load and cancellation.

The "principal-level" in the name is deliberate: this skill is not a language tutorial. It assumes fluency with Rust's fundamentals and focuses on the *craft* of engineering — the decisions that separate code that happens to compile from code that is demonstrably correct, maintainable, and fit for production.

The two failure modes of Rust engineering are equally damaging:

How to install

The exact contents, by fingerprint

mdr add lazyisefficient/agentic-os/rust-engineer@sha256:2dc12aba3fe0faa0

The line at the top of this page pins the label git:20260716.7c29779, 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.
