format_rust SKILL.md skillA

format_rust from theafh/ai-modules is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add theafh/ai-modules/format_rust@v1.3.2

Pins v1.3.2 in mdr.lock. Pin the fingerprint instead.

Apply clippy-aligned Rust practices when writing or editing Rust code (.rs). Covers procedural flow, clippy-driven clarity improvements, minimal imports, Result/Option idioms, the error-versus-invariant model with panic discipline and clippy unwrap_used enforcement, fallible builders following the error idiom by consumer, string prefix/suffix handling, borrowing clarity, iteration style, string building, and function signature grouping.

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

# format_rust

## Preferred style

Use clear, procedural flow with small, single‑purpose functions and explicit data flow; keep names concrete so intent is obvious at a glance.

## Clippy‑driven improvements

Write code that naturally satisfies clippy by choosing the simplest correct form, and treat clippy warnings as signals to improve clarity, safety, and maintainability.

## Imports

Use only necessary imports and prefer direct module paths; remove unused imports promptly to keep warnings clean.

## Errors versus broken invariants

Treat a failure the world causes, such as a missing file, malformed input, a value that does not parse, or a timeout, as a `Result` the caller handles with `?`. Treat a failure that means one of the program's own guarantees is false as a panic, because continuing would compute on state already known to be void. Reach for `unwrap` only in that second category: it is an assertion, not a fallback. At each fallible call, decide whether failure there means the world is wrong or the code is wrong, and route accordingly. Using `unwrap` because writing the error type is tedious claims a broken invariant while actually sitting in an unhandled error.

How to install

The exact contents, by fingerprint
mdr add theafh/ai-modules/format_rust@sha256:ecd5d410d591a0cf

The line at the top of this page pins the label v1.3.2, 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.
