rust-core-language SKILL.md skillA
rust-core-language from fusengine/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add fusengine/agents/rust-core-language@git:20260927.43a351cPins git:20260927.43a351c in mdr.lock. Pin the fingerprint instead.

Use when writing or reviewing idiomatic Rust — edition 2024 ownership/borrowing design, or fixing LLM pitfalls (clone tax, unwrap infestation, indexed loops). Not for error-type design (rust-error-handling) or SOLID layout (solid-rust).
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
<objective> This skill covers idiomatic Rust for stable 1.98.1, edition 2024: designing function signatures and data flow around ownership and borrowing, and using edition-2024 features (let chains, async closures) correctly. It also covers correcting the recurring failure modes of machine-generated Rust: the clone tax (cloning to silence the borrow checker instead of redesigning ownership), unwrap/expect infestation, String vs &str misuse, indexed loops instead of iterators, and over-annotated lifetimes the compiler could elide. Out of scope: error-type design (thiserror vs anyhow) belongs to rust-error-handling; async runtime questions belong to rust-async-concurrency; SOLID/file-layout rules belong to fuse-solid:solid-rust. </objective> # Rust Core Language Idiomatic Rust for stable **1.98.1**, **edition 2024**. This skill covers what the compiler will not catch for you: ownership design that avoids gratuitous cloning, and the recurring failure modes of machine-generated Rust. ## Agent Workflow (MANDATORY) 1. **fuse-ai-pilot:research-expert** — confirm the current stable version and any feature's stabilization release before relying on it (versions move fast). …

How to install
mdr add fusengine/agents/rust-core-language@sha256:100bffed4e3da209The line at the top of this page pins the label git:20260927.43a351c, 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.
