rust-idiomatic from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lu1sdv/skillsmd/rust-idiomatic@git:20261103.3acb4abPins git:20261103.3acb4ab in mdr.lock. Pin the fingerprint instead.

Use when writing or reviewing ordinary Rust, fixing move/borrow/lifetime errors, handling Option or Result, choosing standard-library string/iterator/I/O APIs, or configuring Cargo workspaces, rustfmt, Clippy, and rust-analyzer. Covers UTF-8, partial moves, allocation semantics, and production error propagation; use specialized skills for API architecture, concurrency, or test-driven work.
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 Idiomatic Make ownership, failure, and boundary behavior explicit. Prefer a standard-library operation and a clear loop over a new abstraction or a clone that hides the problem. ## Quick Reference: routing | Task / symptom | Read | |---|---| | Syntax, trait bounds, moved value, overlapping borrows, lifetime error | [Language and ownership](references/language-ownership.md) | | `Option`, `Result`, conversions, parsing, error context | [Errors and idioms](references/errors-idioms.md) | | UTF-8, iterator consumption, capacity, lines, files, paths, time | [Standard-library boundaries](references/stdlib-boundaries.md) | | Cargo, workspace selection, MSRV, editor, lint, debugger | [Project workflow](references/project-workflow.md) | Load only the relevant reference; all four are independent of sibling skill installs. ## Quick Reference: decisions | Need | Default | Watch for | |---|---|---| | Read text / sequence | `&str` / `&[T]` | Borrowed output cannot outlive its owner | | Mutate elements | `&mut [T]` | Use `&mut Vec<T>` only for vector-specific changes | | Retain or consume input | `T` | Move an existing owner rather than cloning | …

How to install
mdr add lu1sdv/skillsmd/rust-idiomatic@sha256:cc6a557d7ee18980The line at the top of this page pins the label git:20261103.3acb4ab, 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.
